The difference between a single-handed grab and a double-action pistol is whether or not the hammer needs to be pulled off manually.
The structure of a single-handed grab is relatively simple, and pulling the trigger can only release the hammer, and there is no other action, so a single-hand grab like Colt's 1872 style requires the hammer of the pistol to be removed before firing, and then the trigger can be pulled to fire.
The structure of the double-action pistol is a bit complicated, you can move the hammer down before firing, at this time, it is equivalent to a single-handed grab, pull the trigger to complete the shooting; You can also pull the trigger directly, and the result of pulling the trigger is to pull the hammer down first and then release it, and both actions are completed by pulling the trigger, so it is called double-action shooting.
This schematic diagram drawn by Li Mu is a schematic diagram of a double-handed pistol.
Li Mu was not a firearms expert before, but as a male citizen of the republic, because he rarely had the opportunity to come into contact with it, so Li Mu has a strong interest in weapons, if you ask Li Mu to draw an AK47 structure diagram, Li Mu really can't draw it, but a simple double-handed pistol is still difficult Li Mu, as long as you have studied high school physics and understand a little leverage principle, you can basically get a simple transmission structure, and you don't need much deep science skills.
After drawing the structural drawing, Li Mu felt that something was missing, so Li Mu thought about it, and casually drew a profile drawing of a Colt 1917 revolver, and then put down the pen with satisfaction.
In fact, to be honest, the Colt 1872 single-handed robbery is really not very good-looking, this kind of gun is a single-action structure, so the structure of the bolt part is very simple, which makes the appearance of the Colt 1872 single-handed robbery not look very coordinated, the barrel is too long, the magazine is too large, the grip is thin and curved, just like an old man who can't do without a cane, or the kind of wind and candle, if it weren't for the feelings of Westerns, Li Muzhen can't fall in love with the Colt 1872 single-handed robbery.
Relatively speaking, the shape of the Colt 1917 revolver is much more coordinated, the barrel is not long, the thickness and arc of the grip are very suitable, the connection between the magazine and the grip does not make people worry about breaking at any time, the front of the magazine is located in the center of the pistol, and the position of the trigger is exactly at the golden section, from the perspective of industrial aesthetics, the 1917 is full of 1872 style.
Just after painting 1917, Li Mu was about to paint the second painting, and Mike brought Li Mu a cup of coffee.
This is one of the few benefits that Mike can provide to Li Mu, although the quality of the coffee is not very good, and there is no added sugar, but the bitter taste reminds Li Mu of his life in the 21st century, and it is Li Mu's commemoration of the 21st century.
When he put the coffee on the table, Mike casually glanced at the drawings drawn by Li Mu.
"God, is this a gun you painted" Mike was very curious, especially after Li Mu spent thousands of dollars, which made Li Mu more and more mysterious in Mike's mind.
You must know that just a few days ago, Li Mu was still a person who couldn't even take out a hundred dollars, and only a few days later, Li Mu didn't even get off the boat, he was able to take out eight thousand dollars, which shocked Mike, just now for most of the day, Mike wanted to break his veterinarian's head, and he didn't understand how Li Mu did it.
"Yes, it's just a gun, I call this kind of gun a double-handed pistol" Li Mu said as a matter of course, without the slightest embarrassment of "plagiarism".
Creativity can never be described as "plagiarism", it can only be a further extension on the basis of so-and-so, not to mention that in this world, the concept of "double-handed pistol" is estimated not yet, Li Mu This is the first time to put it forward, this is simply a complete innovation, or an invention.
Well, speaking of which, maybe it's not bad to be a big inventor, but I don't know if I can be more awesome than Edison, if Li Mu can also have one or two thousand patents in his hand, then Li Muke will be awesome, not to mention millionaires, minutes are the rhythm of the world's richest man.
Mike seemed to be very interested in the drawing drawn by Li Mu, and after obtaining Li Mu's consent, even though there was Li Mu's explanation, Mike took the drawing and looked at it over and over for a long time, but he didn't understand it.
Not everyone has the opportunity to receive a systematic education in the 21st century, so even if Li Mu puts the drawings in front of Mike, Mike can't read them.
However, for Li Mu's explanation of the concept of "double-handed pistol", Mike can still understand, after listening to Li Mu's explanation, Mike looked at Li Mu's eyes and added a cautious component: "Are you planning to apply for a patent?"
See, Mike unconsciously began to use honorifics, which fully illustrates the importance of knowledge, and erudite people deserve respect in any era.
By "patent", Mack refers to the patent law promulgated in the United States in 1790, which is also the most systematic and comprehensive patent law at present.
The United States is a country that attaches great importance to the protection of intellectual property rights, and since about 1641, there have been records of "patents" in the United States, and the U.S.
Federal Constitution of 1787 stipulates that "in order to promote scientific and technological progress, Congress will grant inventors limited exclusive rights for a certain period of time", which is the prototype of patent law.
"No, no, I'm going to sell it to someone for some income, you know, my money has always been spent quickly."
Li Muzhen does not plan to apply for a patent, because there is a publicity period of several months for applying for a patent, and Li Mu cannot afford to wait.
If the Chu Xue family is left in San Francisco, then at most a month, Li Mu will have to pick up the Chu Xue family from San Francisco, 24 US dollars sounds like a lot, but it is not enough for the Chu Xue family to spend too long in San Francisco, since the Chu Xue family is out of the hands of the little fat man, then Li Mu will be responsible for the Chu Xue family.
Mike couldn't help nodding after hearing Li Mu's explanation, Mike naturally knew that Li Mu spent money very quickly, and in just a few days, Mike watched Li Mu spend eight thousand dollars, which is no one else in this era.
"So how much do you want to sell," Mike looked a little moved.
"Not sure, it depends on how much it costs to take the train from San Francisco to New England, the cost of a ticket for at least five people, and the cost of living in New England for five people for a certain amount of time."
It's not that Li Mu doesn't have a complete plan, but he doesn't know the price level of this year, and Li Mu can probably calculate the cost of living, and the ticket is confused.
"Train tickets are not expensive, no more than 30 dollars per person, maybe just over 20 points, the price level in New England is indeed a bit high in the United States, but it is not as high as that, five people only need 50 dollars at most if calculated according to three months, that is, you want to sell this drawing for 200 dollars or 150 dollars."
Mike climbed the table and wrote and drew for a long time, and finally came up with a number Well, it's two numbers or a range.
It seems that Mike's math score is still very good, and he can even multiply Who said that the level of mathematics in the United States is scum:
