[0032] Each guide rod 9 has a limit block fixedly installed at its end away from the movable claw 8. The slide 6 is located between the limit block and the movable claw 8.

[0033] Two guide rods 9 correspond one-to-one with two springs 10, and each spring 10 is sleeved on the corresponding guide rod 9.

[0034] The electric saw 20 is rotatably mounted on the slide 6. The electric saw 20 is driven by the moving jaw 8 through a linkage mechanism. The linkage mechanism is used to drive the electric saw 20 to rotate.

[0035] Specifically, the linkage mechanism includes a drive shaft 13 and a rotating shaft 19. Both the drive shaft 13 and the rotating shaft 19 are rotatably mounted on the slide 6. The slide 6 is a U-shaped seat, and the drive shaft 13 is transversely positioned between the two distal ends of the U-shaped seat and rotatably connected to the two distal ends of the U-shaped seat. The rotating shaft 19 passes through one of the distal ends of the U-shaped seat and is rotatably connected to that distal end.

[0036] The drive shaft 13 is connected to the movable jaw 8 via a first transmission component, which drives the drive shaft 13 to rotate.

[0037] Specifically, the first transmission component includes a rack 11 and a gear 12. The rack 11 is located between the movable jaw 8 and the slide 6, and is fixedly connected to the movable jaw 8. The rack 11 passes through the slide 6 along the moving direction of the movable jaw 8 and is in a limiting sliding engagement with the slide 6.

[0038] The chainsaw 20 is fixed on the rotating shaft 19, which is connected to the transmission shaft 13 via a second transmission component. The second transmission component is used to drive the rotating shaft 19 to rotate.

[0039] Specifically, the second transmission component includes a worm gear 18 and a worm 16. Two support plates 17 are fixedly mounted on the far end of the U-shaped seat where the rotating shaft 19 is located. The worm 16 is placed horizontally between the two support plates 17 and is rotatably connected to the two support plates 17. The worm gear 18 is fixedly sleeved on the rotating shaft 19, and the worm gear 18 and the worm 16 are meshed together.

[0040] A first bevel gear 14 is fixedly mounted on the drive shaft 13, and a second bevel gear 15 is coaxially and fixedly connected to the worm gear 16. The first bevel gear 14 and the second bevel gear 15 mesh with each other.

[0041] Both the fixed jaw 7 and the movable jaw 8 are V-shaped clamps. Together, the fixed jaw 7 and the movable jaw 8 form a diamond-shaped clamping mechanism.

[0042] Anti-slip pins 21 are fixedly installed on the opposite end faces of the fixed claw 7 and the movable claw 8.

[0043] The fixed claw 7 has a through hole for the movable claw 8 to make way.

[0044] Working principle: When using this clamp saw to prune garden trees, first, the clamp saw is fixedly installed onto the excavator's rocker arm via the connecting frame 2. Simultaneously, it is connected to the controller inside the excavator via a connecting cable to control the start and stop of the motor 3 and the chainsaw 20. This is existing technology and will not be elaborated upon here.

[0045] Next, the excavator is driven to the tree that needs to be pruned, and the clamp saw is moved to the tree trunk that needs to be pruned by using the rocker arm. At this time, the tree trunk that needs to be pruned is positioned between the moving jaw 8 and the fixed jaw 7, and the fixed jaw 7 is brought into contact with the tree trunk that needs to be pruned. The above technology is also existing technology and will not be described in detail here.

[0046] Next, the motor 3 and the electric saw 20 are started via the controller. At this time, the output shaft of the motor 3 drives the lead screw 4 to rotate, and the lead screw 4 pushes the moving block 5 to move along the limit slide groove. The moving block 5 drives the slide 6 to move closer to the fixed jaw clamp 7 via two connecting blocks, and the slide 6 pushes the moving jaw clamp 8 closer to the fixed jaw clamp 7 via two springs 10.

[0047] Afterwards, the movable jaw 8 contacts the tree trunk to be pruned, and then abuts against the trunk. At this time, the two springs 10 are compressed, and the slide 6 moves closer to the movable jaw 8. During this process, the rack 11 drives the gear 12 to rotate, and the gear 12 drives the drive shaft 13 to rotate. The drive shaft 13 drives the first bevel gear 14 to rotate, and the first bevel gear 14 drives the second bevel gear 15 to rotate. The second bevel gear 15 drives the worm gear 16 to rotate, and the worm gear 16 drives the worm wheel 18 to rotate. The worm wheel 18 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the chainsaw 20 to rotate.

[0048] After the tree trunk is completely cut by the chainsaw 20, the motor 3 and chainsaw 20 are turned off. The excavator's boom, via the connecting frame 2, fixed seat 1, fixed jaw 7, and movable jaw 8, moves the cut tree trunk from the height to the ground. Then, the motor 3 is restarted, and its output shaft reverses, causing the lead screw 4 to reverse as well. At this time, the slide 6 moves away from the fixed jaw 7, and the two springs 10 extend and return to their original position. When the slide 6 contacts and abuts against the limit blocks on the two guide rods 9, the slide 6 pushes the two limit blocks away from the fixed jaw 7, and the two limit blocks drive the corresponding guide rods 9 to move away from the fixed jaw 7. The two guide rods 9 then drive the movable jaw 8 to move away from the fixed jaw 7. Finally, the tree trunk is removed from the fixed jaw 7.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
