[0005] Furthermore, a gasket is provided between the pin-bearing tooth plate and the auxiliary pin-bearing plate. The thickness of the gasket between the pin-bearing tooth plate and the auxiliary pin-bearing plate can be adjusted to meet the requirements of high-strength nail driving and nail insertion of different lengths.

[0006] Furthermore, the pin support tooth plate is disc-shaped, and asymmetric teeth are arranged on the edge of the pin support tooth plate.

[0007] Furthermore, the two sides of the asymmetric tooth have tooth surfaces with different curvatures, wherein the curvature of the tooth surface on one side is greater than the curvature of the tooth surface on the other side.

[0008] Furthermore, the auxiliary nail plate has auxiliary teeth, wherein two sides of the auxiliary teeth have tooth surfaces with the same curvature.

[0009] Furthermore, the plastic toothed disc has shifting teeth, wherein two sides of the shifting teeth have flat tooth surfaces with inclined angles.

[0014] The upper, middle and lower layers are responsible for nail positioning, nail auxiliary support and plastic strip positioning respectively. Each layer uses the relative position with the main shaft spline to realize the precise positioning of the nail and the plastic strip, so that the front end (nail tip) of the nail can naturally fall into the upper hole of the plastic strip after leaving the nail lifter at the cutting point, providing a basis for the subsequent pressing of nails. At the same time, when the pressure head is pressed down, the middle part of the nail is still in the tooth groove of the nail bearing tooth plate, which can ensure the precise positioning of the nail when it is pressed down.

[0015] 2. The tooth shape of the nail-bearing tooth plate adopts an asymmetric design (one side is straight and the other side is beveled), which is convenient for the nail to enter the nail-bearing tooth plate from the track, and also convenient for the nail to be detached from the nail-bearing tooth plate after being inserted into the plastic strip.
