In this embodiment, the unidirectional rotation member may be a unidirectional bearing, or may be a ratchet structure as shown in fig. 8. The unidirectional bearing is a common structure, and will not be described in any more detail herein, and the ratchet structure in this embodiment is mainly described. As shown in fig. 8, the unidirectional rotation member 45 has a ratchet 451, a pawl 452 and a pawl shrapnel 453, the ratchet 451 is sleeved on the output end 443 and has a plurality of ratchets 4511, the pawl 452 is arranged on the speed reducer 442 positioned at the side edge of the ratchet 451, the pawl 452 is used for being inserted between the ratchets 4511 to cooperate with the ratchet 452 so as to enable the ratchet 451 to rotate unidirectionally, one end of the pawl shrapnel 453 is fixed on the speed reducer 443 through a bolt, and the other end of the pawl shrapnel 453 is abutted against the pawl 453 so as to enable the pawl shrapnel to always have a trend of moving towards the pawl 452 and being inserted into the ratchets 4511.
Fig. 9 is one of the process drawings of the pushing member of embodiment 1 of the present utility model which cooperates with the piston and pushes the piston to move.
Fig. 10 is a second diagram of the process of the pushing member of embodiment 1 of the present utility model cooperating with the piston and pushing the piston to move.
As shown in fig. 9 and 10, the pushing member 43 is driven by the motor body 441 to rotate clockwise, and as the pushing member 43 rotates, the second pushing end 432 moves to the second pushing end 412 and abuts against the second pushing end 412, at this time, the pushing member 43 continues to rotate, the second pushing end 432 moves in an arc shape in a direction substantially toward the energy storage direction, an arc pushing force in the direction substantially toward the energy storage direction is applied to the piston 41 by the second pushing end 412, and the piston 41 can move in the energy storage direction along the guide rod 48 under the pushing force, and compresses the force supply spring 42 to store energy.
The second pushing end 432 is rotated in the energy storage direction to the maximum stroke, thereby completing the first energy storage. At this time, the pushing member 43 continues to rotate, the second pushing end 432 rotates along with it and is separated from the second pushing end 412, meanwhile, the first pushing end 431 rotates to the first pushing end 411 and abuts against the first pushing end 411, and then, the first pushing end 431 pushes the piston 41 to move further towards the energy storage direction in the same manner until the first pushing end 431 rotates to the maximum stroke along the energy storage direction, so as to complete the second energy storage section, thereby completing the whole spring energy storage process.
After the second section of energy storage is completed, the nail can be shot. When the nail is ejected, the motor body 441 drives the pushing member 43 to continue to rotate, the first pushing end 431 rotates along with the first pushing end 411 and is separated from the first pushing end 411, at this time, the first pushing end 431 and the second pushing end 432 are both located outside the moving path of the piston 41, so that the piston 41 can move towards the direction of ejecting the nail under the action of the elastic force of the force supply spring 42 until the firing pin 49 impacts the nail to eject the nail, and the nail ejecting process is completed. In the first stage energy storage or the second stage energy storage, the crank 430 does not rotate reversely under the acting force of the piston 41 due to the arrangement of the one-way bearing, so that the false nail is caused.
The motor body 441 is used for driving the pushing member 43 to rotate, so that the pushing member 43 pushes the piston 41 to move, so that the force supply spring 42 is compressed and stored, and finally the piston 41 is pushed out under the elastic force of the force supply spring 42.

The first pushing end 431 and the second pushing end 432 of the present embodiment are both cylindrical, and the outer diameter of the second pushing end 432 is smaller than that of the first pushing end 431, and the outer diameters of the two ends are unequal. The inventors conducted reference experiments on this as follows:
As shown in fig. 11, in the present embodiment, the outer diameter of the first pushing end 431 is 18mm (radius is 9 mm), the outer diameter of the second pushing end 432 is 14mm (radius is 7 mm), the distance between the first pushing end 411 and the second pushing end 412 of the piston is 35mm, and the working stroke that can be achieved by the experiment is 81.5mm.
As shown in fig. 12, as a control group of the present embodiment, the outer diameters of the first pushing end 431 and the second pushing end 432 are 14mm (the radius is 7 mm), the distance between the first pushing end 411 and the second pushing end 412 of the piston is 35mm, and the working stroke achieved by the experiment is 79.5mm, which is significantly smaller than the stroke achieved by the present embodiment.
The operation mode formed by the work is as follows:
the working stroke is S, the distance between the first pushing end and the second pushing end of the piston is L, the included angle between the first pushing end 431 and the second pushing end 432 is n (i.e. the included angle between the first crank arm 4301 and the second pushing end 432), and the arc length calculation formula bypassed when the first pushing end 431 and the second pushing end 432 rotate is: l=nrr/180 °; when the first pushing end 431 and the second pushing end 432 are equal in diameter (the radius is R), the working stroke of the piston is s=l+l=l+ (n pi R/180 °); when the first pushing end 431 and the second pushing end 432 are not equal in diameter (radius R1 and R2 respectively), s=l+l+ (R1-R2). It is apparent that at unequal diameters, the working stroke of the piston is greater than at equal diameters by a distance (R1-R2). That is, the maximum working stroke is obtained by adjusting the outer diameter of the pushing end as much as possible without changing the length of the pushing end of the piston, and the larger the working stroke, the larger the amount by which the force spring 42 is compressed, so that the larger energy can be obtained, and the gun nail can be ejected more forcefully and promptly.

Example operation and Effect
According to the nail shooting energy storage assembly in the above embodiment, since the guide sleeve 481 is arranged between the guide rod 48 and the force supply spring 42, the guide sleeve 481 not only can guide the movement direction of the force supply spring 42 and prevent the force supply spring 42 from bending deformation in other directions when contracting, but also can reduce the abrasion and friction of the force supply spring 42 in the moving process, so that the service life of the force supply spring 42 is longer, the contraction is smoother, and the energy storage is performed more rapidly.
According to the nail shooting energy storage control mechanism and the nail shooting gun of the above embodiments, since the poking part 471 of the safety switch 47 is provided with the poking sheet 4711, the poking rod 4712 and the poking sheet seat 4713, the poking sheet 4711, the poking rod 4712, the poking sheet seat 4713 and the pushing member 43 are mutually linked to play a role of turning on and off the electric signal of the safety switch 47, and the nail shooting energy storage control mechanism belongs to a mechanical structure control mode without additionally arranging a controller, thereby saving the cost and ensuring more stable control.
According to the nail shooting energy storage control mechanism and the nail shooting gun of the embodiment, the pushing member 43 is arranged and is directly matched with the piston 41, so that the piston 41 is pushed to move towards the force supply spring 42, the force supply spring 42 is enabled to compress and store energy, the pushing member 43 is not in direct contact with the firing pin 49, the movement of the piston 41 is prevented from being influenced due to the contact with the firing pin 49, and the whole energy storage process is smoother and stable.
