[0031] A driving ring 6 is fixedly connected to the upper side of the linkage rod 3, and a band groove 7 is formed on the driving ring 6. A sliding opening 8 is formed on one side of the inner wall of the cavity block 2, and a driving rod 9 that is slidably matched with the band groove 7 is slidably matched on the inner wall of the sliding opening 8;

[0032] An extrusion trigger mechanism 10 cooperating with the driving rod 9 is installed on the inner wall of the U-shaped frame 1, a clamping mechanism 11 cooperating with the gear 5 is installed on one side of the cavity block 2, and a limiting mechanism 12 is installed between the driving rod 9 and the sliding port 8.

[0033] One aspect of the application of this embodiment is as follows: when in use, the pin needs to be installed in the clamping mechanism 11 first, and then the clamping mechanism 11 and the cavity block 2 are connected to each other. After the connection, the plate is placed on the upper side of the inner wall of the U-shaped frame 1, and the pin is pressed down by squeezing the trigger mechanism 10, so as to achieve the installation of the pin;

[0034] After one is installed, the hydraulic cylinder 101 moves back, driving the trigger plate 102 to move upward, and the trigger plate 102 pushes the drive rod 9 to move upward in the sliding opening 8, and the drive rod 9 slides in the band slot 7. During the movement, the drive ring 6 will rotate. After moving to the uppermost side, the trigger plate 102 moves downward, and the drive rod 9 is squeezed and reset by the reset spring 123, thereby realizing the operation and rotation of the linkage rod 3. During the rotation of the linkage rod 3, the clamping mechanism 11 is driven by the gear 5 to realize the movement, and multiple pin positions are changed, so that automatic loading can be realized when installing wooden boards at different positions, avoiding frequent switching between loading and moving boards.

[0035] By setting the drive ring 6, it is possible to drive the drive rod 9 to slide in the band groove 7 during the process of the extrusion trigger mechanism 10 pressing the pin back and forth, thereby driving the drive ring 6 to flip, and then the linkage rod 3 drives the drive rod 9 to flip, so that the clamping mechanism 11 changes position, and different pins are fed to realize automatic feeding of pins, avoiding frequent feeding that causes physical and mental fatigue of personnel, and improving the efficiency of the device during use.

[0036] The extrusion trigger mechanism 10 of this embodiment includes a hydraulic cylinder 101 fixedly connected to the upper side of the inner wall of the U-shaped frame 1, a trigger plate 102 fixedly connected to the output end of the hydraulic cylinder 101 and matched with the sliding drive rod 9, and an impact rod 103 fixedly connected to the lower side of the trigger plate 102;
