[0036] like Figure 2-5 As shown, the nail pusher 5 provided by the utility model includes a nail box 100 and a pin pusher assembly 200, wherein the nail box 100 includes a box body 110, and a slide groove 120 for placing strap nails is opened in the box body 110; the nail pusher assembly 200 is slidably set in the slide groove 120 for pushing the strap nails; wherein, the nail box 100 includes a box body 110, and a slide groove 120 is opened inside the box body 110, and a needle outlet is set at the front end of the slide groove 120, and a clamping plate 130 is set on both sides of the rear end of the box body 110, and a limiting protrusion 140 is set on the inner side of the bottom of the clamping plate 130, and the cover plate 211 is located below the limiting protrusion 140 and slides.
[0037] The push pin assembly 200 includes a cover plate 211, a push rod 220, a spring 230 and a push pin block 300, wherein the front end of the cover plate 211 is provided with a front baffle plate 214, and the rear end thereof is provided with an abutment plate 215; the front end of the push rod 220 is inserted into the push pin block 300, and the rear end thereof is clamped on the abutment plate 215, and the outer periphery of the push rod 220 is provided with a spring 230; the spring 230 is compressed and positioned between the abutment plate 215 and the push pin block 300; the push pin block 300 can slide on the outer periphery of the push rod 220, and the front baffle plate 214 can prevent the push pin block 300 from sliding out of the push rod 220.
[0038] like Figure 6-7 As shown, side plates 350 are provided on the left and right sides of the push nail block 300, and grooves 310 are provided on the top and bottom surfaces of the push nail block 300. A circular hole 330 is provided inside the push nail block 300, and a step hole 340 is provided at the front end of the circular hole 330. A cross groove 320 is provided on the front surface of the push nail block 300.

[0042] When the strap nail is used up, the front end of the side panel 350 moves to the needle outlet, and the side panel 350 contacts the front panel of the slide groove 120. Since the front end of the side panel 350 is an arc-shaped surface, a gap is formed between the side panel 350 and the bottom of the front panel of the slide groove 120, and the gap is opposite to the needle pressing head. When the needle pressing head performs the needle pushing operation, the needle pressing head squeezes the side panel 350 from the gap, thereby preventing the collision with the side panel 350 from causing deformation of the nail pushing block 300.
[0043] Working principle of the branch binding machine: The branch binding machine includes a standby state, a belt grabbing state, a branch binding state, and a binding and belt cutting state. A clamping device 1 is provided at the front end of the bow frame 2, wherein the binding belt can be pulled out from the front end of the frame 4. A nail outlet is provided at the front end of the nail pusher 5, and the clamping device 1 cooperates with the nail outlet. In the standby state, the position of the bow frame 2 relative to the frame 1 is an open position. In the belt grabbing state, force is applied by squeezing the handle 3, and the bow frame 2 rotates downward in a clockwise direction relative to the frame 4. As the bow frame 2 rotates until the clamping device 1 contacts the front end of the frame 4, the clamping device 1 clamps the binding belt. When in the branch tying state, release the pressing force on the handle 3 and the bow frame 2 rotates upward in the counterclockwise direction. As the bow frame 2 rotates, the binding strap is lengthened; after the branch tying machine is inserted into the position of the branches to be tied, the binding strap is made to surround the branches to complete the branch tying; in the binding and cutting state, after the binding strap is adjusted to a suitable position for the branches, the handle 3 is pressed at this time, and the bow frame 2 moves downward again until the clamping device 1 contacts the front end of the frame 4, and the handle 3 is further pressed, and the binding strap nails in the nail pusher 5 bind the binding strap from the nail outlet; then release the handle 3, and the bow frame 2 returns to the open position again, completing a branch tying operation. Repeating the above actions can realize the branch tying operation on various branches.
