When the movable handle 12 moves toward the fixed handle 11 under the external force, the pry bar type linkage reset mechanism 5 follows the movable handle 12 to start running. The pry bar type linkage reset mechanism 5 runs to drive the staple striking assembly 4 to move in an elastic sliding mechanism 3 to enable the staple striking assembly 4 to get away from the staple outlet 21. When the external force disappears, the pry bar type linkage reset mechanism 5 is reset, and the staple striking assembly 4 moves toward the staple outlet 21 through the elastic sliding mechanism 3 and is in contact with the staple storage mechanism 2 at the same time.

[0031] As shown in FIG. 3, the staple striking assembly 4 includes a staple striking plate 41 slidably arranged in the staple outlet 21, and one end, far away from the staple outlet 21, of the staple striking plate 41 is connected to a sliding plate 42. The staple striking plate 41 with a thickness equal to or less than that of a staple is used for pushing the staple out. One end of the staple striking plate 41 is connected to the sliding plate 42 so that the staple striking plate 41 can be pushed out or tightened by moving the sliding plate 42. Moreover, the thickness of the sliding plate 42 is more than that of the staple striking plate 41, thereby being capable of prolonging the service life of the staple striking plate 41.

[0032] The elastic sliding mechanism 3 includes a sliding groove 31 arranged on one side inside the staple gun shell 1, the sliding plate 42 is slidably arranged in the sliding groove 31, one end of the sliding groove 31 is provided with a staple output base 32, the staple outlet 21 is formed on one side of the staple output base 32 in an axial direction, a bending part 43 extending downward is arranged between the staple striking plate 41 and the sliding plate 42, a staple striking torsion spring 33 is arranged in the staple gun shell 1, one end of the staple striking torsion spring 33 acts on the bending part 43, and the other end of the staple striking torsion spring acts on the staple gun shell 1 or the movable handle 12.

The bending part 43 of the sliding plate 42 has the effect of pushing the staple striking plate 41 out. The staple striking torsion spring 33 is tightened through the backward movement of the sliding plate 42. When the sliding plate 42 is released, the staple striking torsion spring 33 returns to drive the bending part 43 of the sliding plate 42 to move forward, thereby generating a push force.

[0033] Specifically, the pry bar type linkage reset mechanism 5 includes a pry bar linkage assembly 6 and a pry bar reset assembly 7 which are arranged in the staple gun shell 1.

[0034] Further, the pry bar linkage assembly 6 includes a linkage base 61 movably arranged in the staple gun shell 1, one end of the linkage base 61 is inserted into a sliding hole 44 at one end, far away from the staple striking plate 41, of the sliding plate 42, and a linkage structure 8, arranged between the linkage base 61 and the movable handle 12, is capable of making the linkage base 61 move synchronously to enable the sliding plate 42 to move far away from the staple striking plate 41 when the movable handle 12 moves toward the fixed handle 11 under an external force. One end of the linkage base 61 is arranged in the sliding hole 44 of the sliding plate 42, and

[0035] the movable handle 12 drives the linkage base 61 to move through the linkage structure 8, thereby enabling the sliding plate 42 to move backward.
