[0043] like Figure 1 As shown, a branch binding machine for preventing tape from slipping is provided in one embodiment of the utility model, comprising a clamping device 1, a bow frame 2, a handle 3, a frame 4, a needle box 5 and a tape box 6, the cross-section of the frame 4 is "U"-shaped; the rear end of the bow frame 2 is hinged to the frame 4, a handle 3 is provided between the bow frame 2 and the frame 4, and the handle 3 and the bow frame 2 are hingedly arranged on the frame 4 in an "x" shape; a tape reel 8 is placed in the tape box 6, the tape reel 8 comprises an inner ring and a tape TP rolled into a reel, the tape TP extends from the tape box 6 to the frame 4 and then passes through the front end of the frame 4.

[0044] A clamping device 1 is provided at the front end of the bow frame 2, and the clamping device 1 can clamp the tape TP from the front end of the frame 4. After the clamping device 1 clamps the tape TP, it is pulled out, and then the tape TP is wrapped around the branches to be tied for binding.

[0045] like Figure 2-4 As shown, the tape box 6 includes a lower box body 61 and an upper box body 68, the upper box body 68 is rotatably connected to the lower box body 61, and the tape reel 8 is placed in the lower box body 61; a boss 62 and a fixing column 671 are provided in the lower box body 61; wherein the boss 62 is cylindrical, and the tape reel 8 is sleeved on the outer periphery of the boss 62; one end of the torsion spring 67 is rotatably connected to the fixing column 671, and the other end of the torsion spring 67 abuts against the inner ring of the tape reel 8 and applies a pre-tightening force to the tape reel 8. When the clamping device 1 clamps and pulls the tape, the tape reel 8 rotates to unwind the tape TP, and the pre-tightening force makes the tape reel 8 have a rotation tendency opposite to the unwinding rotation direction; as shown in FIG.
