[0037] Embodiment 1:

[0038] Please refer to Figure 1-Figure 4 A branch pulling device, comprising a first fixing seat 1, a second fixing seat 2 is arranged on one side of the first fixing seat 1, the first fixing seat 1 is rotatably connected to one end of the second fixing seat 2, the other ends of the first fixing seat 1 and the second fixing seat 2 are both fixed with a connecting block 6, and the two connecting blocks 6 are connected by a fastening bolt 24; wherein, a plurality of fixing bases 3 are fixed to the top of the first fixing seat 1 and the second fixing seat 2, a fixing ring 4 is fixed to the top of the fixing base 3, and a branch pulling rod 5 is hung on the top of the fixing ring 4, so that the branch pulling operation is performed on the branch through the branch pulling rod 5;

[0039] A fixing assembly 7, which is arranged at the inner side of the first fixing seat 1 and the second fixing seat 2, and is used to install and fix the first fixing seat 1 and the second fixing seat 2;

[0040] The fixing assembly 7 includes two moving plates 10, which are respectively arranged on the inner side of the first fixing seat 1 and the second fixing seat 2 close to each other. The moving plate 10 is slidably connected to the first fixing seat 1. A connecting telescopic rod 16 is fixed to the side of the two moving plates 10 close to each other. A contact plate 9 is fixed to the telescopic end of the connecting telescopic rod 16, so that the contact plate 9 and the moving plate 10 are connected and fixed by connecting the telescopic rod 16. The outer side of the connecting telescopic rod 16 is provided with a first spring 15, so that the damage to the tree trunk can be effectively reduced during installation. One end of the first spring 15 is fixedly connected to the moving plate 10, and the other end of the first spring 15 is fixedly connected to the contact plate 9. The first fixed seat 1 and the second fixed seat 2 are fixedly connected to the positions corresponding to the two ends of the moving plate 10, so that the moving plate 10 can be rotationally limited by the limiting telescopic rod 11 to prevent the moving plate 10 from rotating. The telescopic end of the limiting telescopic rod 11 is fixedly connected to the moving plate 10, and the first fixed seat 1 and the second fixed seat 2 are both provided with a driving assembly at the inner position close to the moving plate 10;

[0041] Further, the driving assembly includes a fixed cylinder 13, which is respectively arranged on the outer side of the first fixed seat 1 and the second fixed seat 2 and at a position corresponding to the movable plate 10. The two fixed cylinders 13 are respectively fixedly connected to the first fixed seat 1 and the second fixed seat 2. A movable sleeve 12 is longitudinally arranged on the inner side of the first fixed seat 1 and the second fixed seat 2 and at a position corresponding to the movable plate 10. One end of the movable sleeve 12 is fixedly connected to the movable plate 10, so that when the movable sleeve 12 moves, it can drive the movable plate 10 to move. The other end of the movable sleeve 12 extends to the fixed cylinder On the inner side of the movable sleeve 13, the movable sleeve 12 is slidably connected with the fixed base 3, and the movable sleeve 12 is slidably connected with the first fixed seat 1 and the second fixed seat 2 respectively. The inner side of the movable sleeve 12 is threadedly connected with a screw 17, so that when the screw 17 rotates, the movable sleeve 12 is driven to move along the axial direction of the screw 17. The end of the screw 17 away from the movable plate 10 extends to the outside of the fixed cylinder 13. The end of the screw 17 located on the outside of the fixed cylinder 13 is fixed with a rotating handle 14, so that the screw 17 is driven to rotate by rotating the rotating handle 14, and the rotating handle 14 is rotatably connected with the fixed cylinder 13;

[0042] Specifically, an anti-slip block 18 is fixed to one end of the screw 17 away from the rotating handle 14, so that the anti-slip block 18 can effectively prevent the movable sleeve 12 from being detached from the screw 17, and the anti-slip block 18 is slidably connected to the movable sleeve 12, and the diameter of the anti-slip block 18 is greater than the diameter of the screw 17;

[0043] It can be seen that during installation, the device is first placed on the main rod so that the main rod is located between the first fixing seat 1 and the second fixing seat 2, and then the first fixing seat 1 and the second fixing seat 2 are connected and fixed by the fastening bolts 24. Then, the rotating handle 14 is rotated to drive the screw 17 to rotate. Since the movable plate 10 cannot rotate under the limiting effect of the two movable sleeves 12, when the screw 17 rotates, the movable sleeve 12 threadedly connected thereto is driven to move along the axial direction of the screw 17, so that the movable sleeve 12 drives the movable plate 10 to move. When the movable plate 10 When moving, the contact plate 9 is driven by the telescopic rod 16 to move toward the direction close to the tree trunk. When the contact plate 9 contacts the tree trunk, the rotating handle 14 is rotated appropriately to make the contact plate 9 fit more closely to the tree trunk, thereby making the device more stably fixed. At the same time, under the elastic action of the first spring 15, damage to the tree trunk caused by the fixing process can be effectively avoided. Then, the branch pulling operation can be carried out by the branch pulling rod 5, which can effectively reduce the damage caused to the tree trunk by the device. The installation method is simple and efficient, which increases work efficiency, reduces the labor intensity of workers, and improves the practicability of the device.

[0044] Embodiment 2:

[0045] The branch pulling device provided in Example 1 is further optimized. Specifically, Figure 5 As shown, the limiting component 8 is arranged at a side position where the first fixing seat 1 and the second fixing seat 2 are away from each other, and is used to limit the device;

[0046] Among them, the fixing assembly 7 includes a moving rod 19, which is vertically arranged at the inner position of the fixed cylinder 13, and the moving rod 19 is slidably connected to the fixed cylinder 13. A limit block 22 is fixed at the lower end of the moving rod 19, so that when the moving rod 19 moves, the limit block 22 can be driven to move, and the limit block 22 is slidably connected to the fixed cylinder 13. A gear 23 is fixed at the position corresponding to the screw rod 17 and the limit block 22, and the limit block 22 is meshed with the gear 23, so that the gear 23 can be limited by the limit block 22 to prevent the gear 23 from rotating. A second spring 21 is sleeved on the outer side of one end of the moving rod 19 close to the limit block 22, so that the limit block 22 can be prevented from sliding by the second spring 21, one end of the second spring 21 is fixedly connected to the fixed cylinder 13, and the other end of the second spring 21 is fixedly connected to the limit block 22;

[0047] Furthermore, the top of the moving rod 19 extends to the outside of the top of the fixed tube 13, and a lifting handle 20 is fixed to one end of the moving rod 19 located outside the top of the fixed tube 13, so that the moving rod 19 can be moved by pulling the lifting handle 20;

[0048] With the above structural design, before installation, the lifting handle 20 is first pulled in the direction away from the limit block 22, so that the lifting handle 20 drives the limit block 22 to move through the moving rod 19. When the limit block 22 moves to disengage from the gear 23, the limit block 22 cancels the limit on the gear 23, and the device can be installed and fixed to the tree trunk by rotating the rotating handle 14. When the installation is completed, the lifting handle 20 is released. At this time, the limit block 22 is pushed in the direction close to the gear 23 under the elastic action of the second spring 21. When the limit block 22 moves to mesh with the gear 23, the limit of the gear 23 by the limit block 22 is completed, and the operation can be completed. At the same time, under the elastic action of the second spring 21, the sliding of the limit block 22 is effectively reduced, thereby causing the limit block 22 to disengage from the gear 23, thereby effectively reducing the rotation of the screw rod 17 without human interference, causing the device to disengage from the tree trunk, effectively increasing the stability of the device and improving the practicability of the device.

[0049] The use process of the branch pulling device provided by the utility model is as follows: before installation, first pull the lifting handle 20 in the direction away from the limit block 22, so that the lifting handle 20 drives the limit block 22 to move through the moving rod 19, and when the limit block 22 moves to disengage from the gear 23, the limit block 22 cancels the limit on the gear 23, and the device can be installed and fixed to the tree trunk by rotating the rotating handle 14. When the installation is completed, the lifting handle 20 is released, and at this time, the limit block 22 is pushed in the direction close to the gear 23 under the elastic action of the second spring 21. When the limit block 22 moves to mesh with the gear 23, the limit block 22 limits the gear 23. During installation, first place the device on the main pole so that the main pole is located between the first fixing seat 1 and the second fixing seat 2, and then fasten the first fixing seat 1 and the second fixing seat 2 by tightening the bolts 24. The fixing seat 2 is connected and fixed, and then the rotating handle 14 is rotated to drive the screw 17 to rotate. Because the movable plate 10 cannot rotate under the limiting action of the two movable sleeves 12, when the screw 17 rotates, it drives the movable sleeve 12 threadedly connected to it to move along the axial direction of the screw 17, so that the movable sleeve 12 drives the movable plate 10 to move. When the movable plate 10 moves, it drives the contact plate 9 to move in the direction close to the tree trunk through the connected telescopic rod 16. After the contact plate 9 contacts the tree trunk, the rotating handle 14 is continued to be appropriately rotated to make the contact plate 9 fit more closely with the tree trunk, so that the device is fixed more stably. At the same time, under the elastic action of the first spring 15, the damage to the tree trunk caused by the fixing process can be effectively avoided. Then, the branch pulling operation can be carried out by the branch pulling rod 5 to complete the operation.
