Referring to fig. 2 and 3, fig. 3 shows a schematic structural diagram of a driving rod 31 in a first position in an embodiment of the present application, one end of the driving rod 31 near a bolt may be formed with two limiting protrusions 310, and the two limiting protrusions 310 may be arranged along a length direction of the driving rod 31 or may form a whole. The frame body 1 is formed with a receiving hole 12 communicating with the caulking groove 11, and the receiving hole 12 may be disposed concentrically with the caulking groove 11. The end of the accommodating hole 12 far away from the caulking groove 11 can be connected with a limiting piece 121, and the limiting piece 121 can be a clamping spring or other parts which can be arranged on the inner wall of the accommodating hole 12 and can be abutted against the limiting protruding block 310.

The driving rod 31 is located on the side of the limit bump 310, the diameter of which is changed to form the driving convex part 312, and the driving convex part 312 may be formed on the outer side wall of the driving rod 31, or may be mounted on the outer side wall of the driving rod 31, or may be formed by the diameter difference of two sides, or may protrude from the outer side wall of the driving rod 31, so that the diameters of the two sides of the driving convex part 312 are consistent. In the embodiment of the present application, the driving protrusion 312 is preferably formed by two side diameter differences, and the rotation stopping portion 311 is disposed at the junction between two portions with different diameters. The driving lever 31 can push the pushing member by the driving protrusion 312, thereby driving the steering wheel 2 to rotate; on the other hand, the urging member can urge the drive lever 31 to return by the drive boss 312, thereby urging the steered wheel 2 to rotate. Thus, the linear motion of the drive lever 31 can be converted into the circular motion of the steered wheel 2 by the pushing member.

Referring to fig. 3 and 4, fig. 4 shows a cross-sectional view of the internal structure of the steering wheel 2 in an embodiment of the present application, the pushing member may include a pushing portion 32, a detent 21, and a pushing member 33, where the pushing portion 32 is sleeved on the driving rod 31 and can slide freely with respect to the driving rod 31, but the sliding freely of the pushing portion 32 is limited by the driving protrusion 312. The center of the pushing portion 32 may be formed with a stop portion 322 that is matched with the rotation stop portion 311, and the stop portion 322 may be a vertical surface that is matched with a flat square or a groove that is matched with a key, so long as the pushing portion 32 can slide freely relative to the driving rod 31 and cannot rotate. The pushing member 33 is housed in the steering wheel 2, and the pushing member 33 may be a spring or other elastic member as long as the restoring force can be provided after the pushing member is pressed. The steering wheel 2 may have a supporting groove formed therein, and the pushing member 33 may have one end placed in the supporting groove and one end abutted against the pushing portion 32. The outer sidewall of the pushing part 32 may be formed with guide surfaces 321, the guide surfaces 321 may be circular arc-shaped, and the number of the guide surfaces 321 may be identical to the number of the conversion sites 20.

The steering wheel 2 may have a hollow cylindrical structure, the detent groove 21 may be formed in the steering wheel 2, and the pushing portion 32 may be located in the detent groove 21.

The driving lever 31 has a first position in which the driving protrusion 312 is in contact with or abuts against the stopper 121, and a second position in which the pushing portion 32 is located on top of the first guide surface 221. In the second position, the pushing portion 32 is located at the bottom of the first guide surface 221, and at this time, the pushing member 33 is deformed and has a tendency to push the pushing portion 32 toward the second guide surface 222. In the process of switching the drive lever 31 from the first position to the second position by the external force, the pushing portion 32 pushes the drive lever 31 to move, and since the drive lever 31 is restricted to move only and cannot rotate, the steering wheel 2 rotates under the guide of the first guide surface 221. When the drive lever 31 is shifted from the second position to the first position, the pushing member 33 pushes the pushing portion 32 against the second guide surface 222, and similarly, the drive lever 31 is restricted from moving only and is not rotatable, so that the steering wheel 2 is rotated under the guide of the second guide surface 222.

The mounting portion 24 is detachably connected with respect to the body 23, thereby facilitating mounting of the pushing portion 32 and the pushing member 33 between the first guide surface 221 and the second guide surface 222.

The mounting portion 24 may be provided with a third guide surface 223 on the side of the second guide surface 222, and the third guide surface 223 may limit the pushing portion 32 when the driving lever 31 is in the second position, preventing the pushing portion 32 from crossing the third guide surface 223. Further, the body 23 may be provided with a vertical surface on the side of the first guide surface 221, so that the pushing portion 32 can be restrained from moving in the direction. Alternatively, at least any one of the first guide surface 221, the second guide surface 222, and the third guide surface 223 may be a slope and/or an arc surface, or may be all of a slope or an arc surface, as long as the pushing portion 32 is guided.

Of course, it will be understood by those skilled in the art that the driving device for driving the steering wheel 2 to rotate herein is not limited to the above driving device, and the steering wheel 2 may be driven to rotate by a motor driving transmission mechanism. The motor is connected with a controller, the controller is connected with a detection device for detecting the movement of the backing plate 13, and the detection device can be a Hall sensor, a trigger switch and the like, so long as the backing plate 13 can be sensed to move and send out a sensing signal. The controller controls the motor to operate in response to the sensing signal to rotate the steering wheel 2 to switch the nails in the switch position 20 to the nailing channel 0. On the other hand, the driving device can also realize the conversion from the linear motion to the circular motion through a transmission shaft of a rack-and-pinion mechanism matched with power transmission and a reversing bevel gear.

The steering wheel 2 is magnetized by the magnetization of the magnetic member 251, and the nail is typically made of iron, so that the steering wheel 2 can attract the nail in the conversion site 20. Optionally, the outer side wall of the magnetic member 251 is wrapped with a plastic shell.

The nail feeding plate 41 is provided with a guide convex part 411 inserted in the guide groove 1521, and the cover plate 152 and the guide groove 152 on the frame body 1 are spliced to form two side walls limiting the guide convex part 411 so as to limit the nail feeding plate 41 to be slidingly connected on the frame body 1 along the extending direction of the guide groove 1521. The nail feeding plate 41 is provided with a trigger part 412, and the trigger part 412 may be a projection protruding from the nail feeding plate 41 or may be attached to the nail feeding plate 41.
