[0039] A positioning rod 3 is provided on the opposite side of the cutting blade frame 21 to cooperate with the cutting blade frame 21 to clamp the branches, wherein the positioning rod 3 includes a first rod 31 and a second rod 32 arranged in parallel and opposite to each other on both sides of the moving track of the cutting blade frame 21;

[0040] The first frame rod 31 and the second frame rod 32 are used to support the branches when the branches are cut by the chain saw 22 on the cutting tool holder 21, and the supporting surface is set to be arc-shaped and can be adapted to fit the surface of the branch, thereby ensuring stability during cutting.

[0041] A medicine storage bin 33 for storing ointment is provided in the first rod 31, and a film storage bin 34 is provided in the second rod 32. A roller 35 for covering the roll of cling film is provided in the film storage bin 34, and a movably detachable cap is provided at the upper end to facilitate the addition of ointment and the placement of the roll of cling film.

[0042] The side end of the second rack 32 is provided with a film outlet 36 for unrolling the cling film, so that one end of the cling film can be extended from the film discharge bin 34 to be unrolled. After the cling film is loaded into the film discharge bin 34, its end is pulled apart and pulled out of the film outlet 36 to a certain length, which is convenient for the film pulling mechanism to pull. At the same time, the roll cling film is a breakpoint cling film, which is convenient for tearing off and covering after applying the medicine.

[0043] The cutting blade holder 21 performs the cutting action of moving toward the side of the positioning frame rod 3 and the rotating action away from the positioning frame rod 3; the track seat 2 is also provided with a film pulling mechanism for pulling the cling film when the cutting blade holder 21 performs the rotating action, and a coating mechanism for coating the cling film on one side when the cling film is pulled out. When the cutting blade holder 21 moves toward the side of the positioning frame rod 3, the chain saw 22 at its upper end cuts the branch. When it is completely cut off, the cutting blade holder 21 is located between the first frame rod 31 and the second frame rod 32. At this time, the cutting blade holder 21 moves back. When it moves back, the film pulling mechanism pulls the end of the cling film extending from the film outlet 36. While pulling, the coating mechanism coats the side of the cling film close to the cut end face of the branch, thereby automatically completing the coating and unfolding of the cling film, and then manually tearing off the film and covering the cut end face of the branch for protection, effectively improving work efficiency.

[0044] In one embodiment, a threaded screw 4 is rotatably provided in the track base 2, a sleeve plate 41 is provided at the bottom of the cutting blade holder 21, which is limitedly slidable in the track base 2 and threadedly sleeved with the threaded screw 4, and a first drive motor 42 is provided on the side support frame 11 to drive the threaded screw 4 to rotate, and the first drive motor 42 can rotate forward and reverse, thereby driving the cutting blade holder 21 to perform reciprocating movement, and a second drive motor 5 is provided on the side of the cutting blade holder 21 to drive the chain saw 22, and the second drive motor 5 slides synchronously with the cutting blade holder 21;

[0045] The handle 12 is provided with a first switch 13 for driving the first drive motor 42 in forward rotation and a second switch 14 for driving the second drive motor 5. When the device is in use, the user holds the handle 12 with his hand and places his forearm on the side support frame 11, which provides a more convenient operating posture;

[0046] The cutting blade holder 21 is also provided with a third switch 51 which drives the first drive motor 42 to reverse and turn off the second drive motor 5 after being triggered. The track seat 2 is provided with a first push rod 52 which is pressed to trigger the third switch 51. The third switch 51 is a spring switch of the prior art, which can be triggered when pressed and pops up in the non-pressed state. The first push rod 52 is arranged at a position a certain distance behind the arc surface of the positioning frame rod 3 relative to the side of the cutting blade holder 21, so that the first push rod 52 will not be engaged with the third switch 51 until the cutting blade holder 21 completes the complete cutting of the branches, thereby shutting down the chain saw 22 and signaling to control the first drive motor 42 to reverse, so that the cutting blade holder 21 automatically moves back.

[0047] In one embodiment, the film pulling mechanism includes a film supporting frame 6 arranged on the second frame rod 32 for supporting the plastic wrap film, and a clamping assembly arranged on the cutting blade frame 21 and clamping the end of the plastic wrap film after the cutting blade frame 21 completes the cutting action. The film supporting frame 6 can support the plastic wrap film forward for a certain distance after it extends from the film outlet 36, so that the clamping assembly can move to the film supporting frame 6 to clamp the end of the plastic wrap film. At the same time, the surface of the film supporting frame 6 that supports the plastic wrap film is smoothly chamfered to ensure that it can slide in accordance with the film supporting frame 6 without destroying the integrity of the film.

[0048] In one embodiment, the medicine applicator mechanism includes a medicine applicator assembly that cooperates with the film support frame 6 to clamp the plastic wrap and a liquid pump assembly that pumps the ointment in the medicine storage chamber 33 into the medicine applicator assembly;

[0049] The coating assembly includes a transfer box 8 arranged on the second frame rod 32, a spray port 81 arranged on the transfer box 8, and a coating roller 82 rotatably arranged in the spray port 81; the coating roller 82 cooperates with the film support frame 6 to clamp the protruding end of the plastic wrap, and drives the coating roller 82 to rotate when the plastic wrap is continuously pulled out, so that when the ointment enters the interior of the transfer box 8, it is sprayed onto the surface of the coating roller 82 through the spray port 81, and then the plastic wrap is pulled and unfolded by the clamping assembly, and then drives the coating roller 82 to rotate. The rotating coating roller 82 can smear the ointment on its surface onto the plastic wrap while the plastic wrap continues to unfold.

[0050] In one embodiment, the clamping assembly includes a first mounting frame 61 provided on the cutting blade holder 21, a main splint 62 rotatably provided on the first mounting frame 61, a second mounting frame 63 provided on the cutting blade holder 21, a secondary splint 64 rotatably provided on the second mounting frame 63, and a hook lock assembly for locking the main splint 62. The main splint 62 and the secondary splint 64 rotate with each other at the same time, so as to clamp the cling film. At the same time, a side of the main splint 62 close to the secondary splint 64 can be provided with a texture to increase friction, or a rubber point can be provided to enhance the friction between it and the cling film, so that the main splint 62 can be pressed on the cling film to stably pull out the cling film and unfold it.

[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 rotate under external force and then lose the external force.

[0052] When locking sill 75 , locking sill 77 is positioned at the top end of locking sill 71 , and locking sill 77 is positioned at the top end of locking sill 71, and locking sill 77 is positioned at the top end of locking sill 71. When locking sill 77 is located at the bottom end of locking sill 71, the locking sill 77 can be locked to the state where locking sill 77 is located.

[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 the branch, the main splint 62 moves to the side of the end of the plastic wrap film, and then moves forward to cause the second push rod 75 to push against the rear end of the lock plate 73, thereby driving the lock plate 73 to deflect and disengage the latch 74 from the latch rod 71, thereby releasing the main splint 62, causing it to rotate toward the auxiliary splint 64 and cooperate with the auxiliary splint 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 blade holder 21 moves back to the end. After the cutting blade 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 is rotated 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 assembly includes a medicine pump box 83 disposed on the track seat 2; a piston plate 84 that slides in a sealed manner within the medicine pump box 83; a piston rod 85 disposed on the piston plate 84 and movably connected to the medicine pump box 83, wherein the piston rod 85 is sealed against the movable portion of the medicine pump box 83 and a return spring 86 that is sleeved with the piston rod 85 and disposed between the piston plate 84 and the inner wall of the medicine pump box 83; a medicine suction pipe 87 having two ends connected to the medicine storage bin 33 and the medicine pump box 83; and a medicine pump pipe 88 having two ends connected to the medicine pump box 83 and the transfer box 8.

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

[0058] A connecting arm 9 is provided at the end of the piston rod 85 away from the piston plate 84, and a pushed rod 91 that slides within the track seat 2 is provided at the 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 pushing the pushed rod 91 is provided at the 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 pushes the pushed rod 91 synchronously 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 rod 3, that is, the end position of the back movement, and then the cutting blade holder 21 and the positioning rod 3 are respectively placed on both sides of the branch to be cut, and at the same time, the positioning rod 3 is made to abut 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, thereby cutting the branch. When the cutting blade holder 21 moves to cut the branch to a certain depth, the fourth abutting rod 93 will abut against the pushed rod 91, and then push the piston rod 85 backward through the connecting arm 9, so that the piston plate 84 moves backward, thereby passing through the suction tube 87 The ointment in the medicine storage bin 33 is drawn into the pump medicine box 83. After the cutting blade holder 21 completely cuts off the branch, the main splint 62 at its side end will be on the side of the spray 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 card rod 71 are disengaged, so that the main splint 62 is released. The main splint 62 rotates and abuts against the side of the spray port 81 under the action of the torsion spring 65. At the same time as the second supporting rod 75 abuts 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. At the same time, the cutting blade holder 21 starts to move back. When it moves back, the main splint 62 will abut against the spray port 81 The auxiliary clamping plate 64 will gradually rotate through the torsion spring 65 when moving back until it is separated from the film support frame 6, and then it will cooperate with the main clamping plate 62 to clamp the cling film, and when continuing to move back, it will pull and stretch the cling film. During the return action, 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 applicator roller 82 through the spray port 81, and then in the process of the cling film gradually being pulled and stretched outward, it drives the applicator roller 82 to rotate so that the ointment on the surface of the applicator roller 82 When the blade 21 is moved back to the end, the third lever 78 will engage with the wedge plate 76, thereby pushing the main splint 62 to deflect to the side away from the auxiliary splint 64. The latch bar 71 at the upper end of the main splint 62 engages with the lock plate 73 and pushes the lock plate 73 to deflect until it disengages. Then the latch bar 71 moves to the position of the latch mouth 74, and the lock plate 73 moves back under the action of the torsion spring 65, so that the latch mouth 74 is buckled on the latch bar 71, thereby locking the main splint 62. At this time, due to the relative opening between the main splint 62 and the auxiliary splint 64, one end of the cling film is released, and 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.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
