By sliding the winding wheel 13 on the fixed plate 11, the winding wheel 13 can pull the second pruning knife 7 to rotate through the steel wire rope 9, thereby facilitating the pruning work of the device;

[0027] Please refer to Figures 1-5 , at the front and rear ends inside the handheld frame 1, fixing plates 11 are fixed, and first sliding grooves 12 are formed on the surfaces of the fixing plates 11. A winding wheel 13 is arranged between the two groups of fixing plates 11, and the central shaft of the winding wheel 13 penetrates through the first sliding groove 12 on the surface of the fixing plate 11. A shaft sleeve 14 is rotatably connected to the central shaft of the winding wheel 13. An electric push rod 15 is fixed above the shaft sleeve 14 inside the upper part of the handheld frame 1. A connecting frame 16 is snap-fitted and slidably connected to the side surface of the fixing plate 11, and an adjusting screw rod 17 is threadedly connected to the middle of the connecting frame 16.
