[0050] In one embodiment, the clamping assembly includes a first mounting frame 61 arranged on the cutting blade holder 21, a main clamping plate 62 rotatably arranged on the first mounting frame 61, a second mounting frame 63 arranged on the cutting blade holder 21, a secondary clamping plate 64 rotatably arranged on the second mounting frame 63, and a hook lock assembly for locking the main clamping plate 62. The main clamping plate 62 and the secondary clamping plate 64 are simultaneously rotated and matched with each other, so that the cling film can be clamped. At the same time, a side of the main clamping plate 62 close to the secondary clamping plate 64 can be provided with a texture for increasing friction, or a rubber point can be provided to enhance the friction between it and the cling film, so that when it is pressed on the cling film, the cling film can be stably pulled out and unfolded;

[0051] Torsion springs 65 are provided between the first mounting frame 61 and the main plate 62 as well as between the second mounting frame 63 and the auxiliary plate 64, so that the two can be stable under normal conditions and can automatically reset when they are rotated by external force and lose the external force.

[0052] When the locking cam 73 is in the state of being moved, the locking cam 73 is in the state of being moved forward, and the locking cam 73 is in the state of being moved forward, so that the locking cam 73 can be locked to the locking cam 73 by the locking cam 73.

[0053] In one embodiment, the transfer box 8 is provided with a second push rod 75 that pushes the lock plate 73 after the cutting action of the cutting blade 21 is completed. When the cutting blade 21 cuts off the branch, the main clamping plate 62 moves to the side of the end of the plastic wrap film, and then moves forward to make the second push rod 75 push against the rear end of the lock plate 73, thereby driving the lock plate 73 to deflect and disengage the bayonet 74 from the clamping rod 71, thereby releasing the main clamping plate 62, causing it to rotate toward the auxiliary clamping plate 64 and cooperate with the auxiliary clamping plate 64 to clamp the plastic wrap film;

[0054] A wedge plate 76 is provided on the main splint 62, and a fixing frame 77 is provided on the track seat 2. A third push rod 78 is provided on the fixing frame 77 for pushing the wedge plate 76 when the cutting tool holder 21 moves back to the end. After the cutting tool holder 21 completes the moving back action, the third push rod 78 can be engaged with the wedge plate 76, thereby pushing the main splint 62 to deflect it. When it turns to a certain angle, it will be hooked and locked by the locking plate 73, thereby releasing one end of the plastic wrap.

[0055] In one embodiment, the end of the auxiliary clamping plate 64 is cylindrical, and the film support frame 6 is provided with an inclined surface that abuts against the auxiliary clamping plate 64 when it approaches, so that the film support frame 6 can push and deflect the auxiliary clamping plate 64 when the auxiliary clamping plate 64 is attached to the film support frame 6.

[0056] In one embodiment, the pump liquid assembly includes a pump medicine box 83 disposed on the track seat 2; a piston plate 84 sealingly sliding in the pump medicine box 83; a piston rod 85 disposed on the piston plate 84 and movably connected with the pump medicine box 83, and the piston rod 85 and the movable part of the pump medicine box 83 are sealed and connected with the piston rod 85 and a return spring 86 disposed between the piston plate 84 and the inner wall of the pump medicine box 83; a medicine suction pipe 87 whose two ends are connected to the medicine storage bin 33 and the pump medicine box 83; a pump medicine pipe 88 whose two ends are connected to the pump medicine box 83 and the transfer box 8;

[0057] A one-way valve 89 is provided between the medicine suction pipe 87 and the medicine pump pipe 88 and the medicine pump box 83, so that the medicine suction pipe 87 can only deliver medicine to the medicine pump box 83 in one direction, and the medicine pump box 83 can only deliver medicine to the medicine pump pipe 88 in one direction;

[0058] A connecting arm 9 is provided at one end of the piston rod 85 away from the piston plate 84, and a pushed rod 91 that slides within a limited position in the track seat 2 is provided at one end of the connecting arm 9 away from the piston rod 85. A connecting rod 92 is provided at the side end of the cutting tool holder 21, and a fourth supporting rod 93 for supporting the pushed rod 91 is provided at one end of the connecting rod 92 away from the cutting tool holder 21. The fourth supporting rod 93 engages with the pushed rod 91 when the cutting action is about to be completed, and simultaneously pushes the pushed rod 91 during cutting, and the return speed of the cutting tool holder 21 is greater than the return speed of the pushed rod 91 under the restoring action of the reset spring 86.

[0059] Working principle: Before the device is used, the cutting blade holder 21 is located at the maximum distance away from the positioning frame rod 3, that is, the end position of the back movement, and then the cutting blade holder 21 and the positioning frame rod 3 are respectively placed on both sides of the branch to be cut, and at the same time, the positioning frame rod 3 is pressed against the outer surface of the branch to locate the cutting point, and then the second switch 14 is manually pressed to drive the second drive motor 5 to start the chain saw 22, and then the first switch 13 is pressed to drive the first drive motor 42 to rotate, thereby driving the cutting blade holder 21 to move toward the branch side, so as to cut the branch. When the cutting blade holder 21 moves to cut the branch to a certain depth, the fourth push rod 93 will be pressed against the pushed rod 91, and then the piston rod 85 is pushed backward through the connecting arm 9, so that the piston plate 84 moves backward, thereby passing through the drug suction tube 87. The ointment in the medicine storage bin 33 is pumped into the pump medicine box 83. After the cutting tool holder 21 completely cuts off the branch, the main splint 62 at its side end will be on the side of the medicine spraying port 81, and the auxiliary splint 64 will abut against the inclined surface of the film support frame 6 and deflect away from the side of the main splint 62. At the same time, the second supporting rod 75 abuts against the rear end of the locking plate 73 to cause it to rotate, and then the bayonet 74 and the bayonet rod 71 are disengaged, so that the main splint 62 is released, and the main splint 62 rotates and abuts against the side of the medicine spraying port 81 under the action of the torsion spring 65. At the same time as the second supporting rod 75 abuts against the locking plate 73, the first supporting rod 52 also synchronously abuts against the third switch 51, thereby stopping the chain saw 22 from working, and at the same time the cutting tool holder 21 starts to move back, and the main splint 62 will abut against the medicine spraying port 81 when it moves back. The auxiliary clamping plate 64 will gradually rotate through the torsion spring 65 during the return movement until it is separated from the film support frame 6, and then cooperate with the main clamping plate 62 to clamp the cling film, and when continuing to move back, the cling film will be pulled and stretched. During the return movement, the piston plate 84 will move back under the action of the return spring 86, and then the ointment in the pump box 83 will be pumped into the transfer box 8 through the pump tube 88, and sprayed to the inner surface of the coating roller 82 through the spray port 81, and then in the process of the cling film being gradually pulled and stretched outward, it drives the coating roller 82 to rotate so that the ointment on the surface of the coating roller 82 The locking plate 73 is pressed against the locking plate 74 to move the locking plate 73 out of the way, and the locking plate 73 is moved back to the locking plate 74. The locking plate 73 is moved back under the action of the torsion spring 65, so that the locking plate 73 is buckled on the locking rod 71, thereby locking the main plate 62. At this time, due to the relative opening between the main plate 62 and the auxiliary plate 64, one end of the cling film is released. Then, a single piece of cling film coated with ointment is manually torn off and applied to the end of the cut surface of the branch to complete the end surface protection work after cutting.
