At the same time, the extension rod 43 is positioned and installed through the sliding connection between the locating pin 31 and the locating groove 38 to prevent the connecting rod 33 from being misplaced, thereby adjusting the height of the collecting bucket 1. At the same time, the present invention elastically pushes the block 34 through the setting of the second spring 35, so that the top end of the connecting rod 33 remains in an extended state for easy installation and fixation.

[0028] In one embodiment of the present invention, see Figures 1 to 8The hook assembly 44 includes a driving shaft 14 rotatably connected between the connecting seats 12, a rotating seat 15 is fixedly connected to the driving shaft 14, a fixed seat 16 is fixedly connected to the second rotating arm 10, a first spring 17 is connected between the fixed seat 16 and the rotating seat 15, the first spring 17 is a tension spring, a connecting block 18 is fixedly connected to the driving shaft 14, a closing block 19 is fixedly connected to the connecting block 18, the two combination blocks 19 are symmetrical to each other, a stop buckle 20 is fixedly connected to the push rod 13, the stop buckle 20 cooperates with the top of the closing block 19, and a closing buckle 21 is fixedly connected to the bottom of the closing block 19, and the two groups of closing buckles 21 are staggered with each other. When the push rod 13 is unfolded to both sides under the action of the branch, the push rod 13 drives the two sets of connecting seats 12 to unfold, and the connecting seats 12 drive the two combination blocks 19 to unfold. At this time, after the branch enters between the first rotating arm 9 and the second rotating arm 10 along the closing block 19, the second rotating arm 10 is elastically closed under the action of the torsion spring 11. At this time, the two combination blocks 19 are synchronously closed under the action of the second rotating arm 10. At this time, the two sets of closing buckles 21 are also staggered and closed under the drive of the closing block 19. After that, when the present invention is hung on the branch, the branch is under the gravity. Under the action of , it is clamped between the two sets of closing buckles 21. At this time, the gravity of the present invention acts on the branch along the closing buckle 21. At this time, the closing buckle 21 drives the two combination blocks 19 to retract and close, thereby preventing the two combination blocks 19 from opening. At this time, the present invention can be hung on the branch. At the same time, the present invention can elastically push the drive shaft 14 through the setting of the first spring 17. The drive shaft 14 drives the closing block 19 to elastically close through the connecting block 18.

At the same time, the present invention can also adjust the height of the present invention according to the height of the branches. During adjustment, the present invention screws the extension rod 43 between the gripping rod 39 and the connecting tube 28 through the first connectors 29 and the first threaded mounting grooves 36 at both ends of the extension rod 43. At the same time, the connecting rod 33 is connected and fixed between the driving rod 41 and the lifting screw 3 through the second connectors 30 and the second threaded mounting grooves 37 at both ends of the connecting rod 33. Then, the lifting rod 33 is shaken to move. The handle 42 drives the driving rod 41 to rotate, and the driving rod 41 drives the second threaded mounting groove 37 to rotate. At this time, the second threaded mounting groove 37 is threadedly connected with the second connecting head 30 and tightened. After the tightening is completed, when the present invention is used to prune the branches, first align the two sets of push rods 13 with the pruning position, and then push the push rod 13 toward the pruning position. At this time, the push rod 13 is expanded to both sides under the action of the branches, and the push rod 13 drives the closing block 19 to expand. At this time, the branches enter between the first rotating arm 9 and the second rotating arm 10 along the closing block 19. At this time, the present invention is suspended on the branch under the action of the closing buckle 21. After the motor 23 is started, the motor 23 drives the saw blade 24 to rotate. At the same time, the staff can shake the crank handle 42, and the crank handle 42 drives the driving rod 41 to rotate. The driving rod 41 is threadedly connected with the second connecting head 30 through the second threaded mounting groove 37 to drive the lifting screw 3 to rotate. The lifting screw 3 drives the lifting screw 3 to rise and fall through the threaded connection with the threaded block 2. The lifting screw 3 drives the traction block 4 to rise and fall. The traction block 4 drives the rotation connection of the two groups of first rotating arms 9 to descend through the connecting shaft 5, and the first rotating arm 9 is lowered during the descent of the first rotating arm 9 through the fixed shaft 8 drives the sliding block 7 to slide in the sliding groove 6. During the sliding process of the sliding block 7 in the sliding groove 6, the sliding block 7 drives the two groups of first rotating arms 9 to rotate and retract through the fixed shaft 8. The first rotating arm 9 drives the two groups of second rotating arms 10 to retract synchronously. At this time, the first rotating arm 9 and the second rotating arm 10 drive the saw blade 24 to retract, thereby driving the saw blade 24 to move toward the branch direction, and then sawing the branch, thereby cutting the branch. At the same time, the sawdust generated during sawing is collected by the collecting bucket 1, and the collected sawdust then enters the collecting bag along the discharge port 27, and then the sawdust is collected by the collecting bag.
