DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figs. 1-6 In the embodiments of the utility model, a tree damage pruning rope threading device comprises a support 1, the support 1 is in a " " character-shaped structure, a flat full hook 2 is arranged at one end of the top of the support 1, an inverted bay open hook 3 is connected to the other end of the top of the support 1, a crossbar 4 is overlapped between the flat full hook 2 and the inverted bay open hook 3, one end of the crossbar 4 is connected to a traction rope 6, and the other end of the crossbar 4 is symmetrically provided with two flat support rods 5 on two opposite sides;

[0024] A telescopic rod is connected to the lower end of the support 1, the telescopic rod comprises a connecting rod 7 connected to the bottom of the support 1, a plurality of telescopic rods 8 are telescopically connected to the lower end of the connecting rod 7, and a locking assembly 9 is arranged between the plurality of telescopic rods 8;

[0025] The support 1, the flat full hook 2 and the inverted bay open hook 3 are all formed by bending steel bars, and the support 1, the flat full hook 2 and the inverted bay open hook 3 are fixedly connected through welding; the distance between the outer ends of the two flat support rods 5 is greater than the inner side width of the inverted bay open hook 3.

[0026] In the embodiments, the tree damage pruning rope threading device can avoid personal injury caused by workers climbing trees to bind ropes when the tree is too high during the process of treating tree damage and pruning, and can also avoid sudden high-altitude falling accidents and tree branch pressure on the wire, thereby causing power line breakage or line tripping and other faults, greatly reducing the occurrence of safety accidents and ensuring personal safety.

[0027] Specifically, when it is needed to hang the rope to the higher branch of the tree, the crossbar 4 is first lifted between the flat hook 2 and the open hook 3 arranged at the two ends of the top of the support 1, and then the position of the support 1 is adjusted by the telescopic rod at the tail end of the support 1 until the support 1 is located at the side above the branch to be cut, and finally the crossbar 4 is thrown out by pushing, and the crossbar 4 falls from the side above the branch to be cut to the other side, so that one end of the traction rope 6 is over the branch, and then the flat support rod 5 at one end of the crossbar 4 is hooked by the open hook 3, and the crossbar 4 is pulled down to complete the hanging of the traction rope 6. At this time, one end of the rope to be hung is connected with one end of the traction rope 6, and the other end of the crossbar 4 is pulled, so that the hanging of the rope is completed. The tree damage branch cutting and rope threading device is simple to operate, and can better complete the task of binding the rope on the higher tree, so as to effectively avoid the personal safety accident hidden danger of the staff binding the rope on the tree, reduce the damage of the line equipment, and cause the power failure and other problems.

[0028] It should be noted that when the crossbar 4 is lifted between the flat hook 2 and the open hook 3, the flat support rod 5 at one end of the crossbar 4 is outside the flat hook 2 or the open hook 3, so as to avoid the interference when the crossbar 4 is pushed. In addition, the crossbar 4 in the present scheme is made of light insulating plastic or insulating metal, and the traction rope 6 is also made of insulating material, so as to be convenient for the staff to lift and save labor. After the crossbar 4 is over the branch, it falls down due to its own gravity, but because there is a large friction force between the traction rope 6 and the branch, the crossbar 4 will be hung in the air, and at this time the crossbar 4 can be hooked by the open hook 3 and pulled down.

[0029] Please refer to Figs. 1-6 The locking assembly 9 comprises a plurality of deformation blocks 901, the plurality of deformation blocks 901 are arranged in a cylindrical structure, one end of the deformation block 901 is integrally formed with the open end of the telescopic rod 8, a first screw thread 903 is arranged on the outer wall of one end of the telescopic rod 8 close to the rough surface 902, a sleeve 904 is sleeved on the outer wall of the open end of the telescopic rod 8, an extrusion groove 905 is arranged in the inner end of the sleeve 904, and a second screw thread 906 matched with the first screw thread 903 is arranged on the inner wall of the other end of the sleeve 904.

[0030] The plurality of telescopic rods 8 are tubular structures with one end open and the other end closed, and the plurality of telescopic rods 8 are hard insulating plastic pipe or insulating metal pipe; the outer wall of the deformation block 901 is arranged in an inclined manner, and the wall thickness of the open end of the deformation block 901 is greater than that of the non-open end.

[0031] The locking assembly 9 further comprises a rough surface 902 arranged on the inner wall of the plurality of deformation blocks 901; the inner diameter of one end of the extrusion groove 905 gradually increases from inside to outside, and the inclination of the extrusion groove 905 is matched with the inclined end of the deformation block 901.

[0032] In the embodiment: by setting the locking assembly 9 between the two adjacent telescopic rods 8, the telescopic amount of the two adjacent telescopic rods 8 can be effectively controlled, and the cross rod 4 can be lifted to any position height within the effective range.

[0033] Specifically, when the position height of the support 1 needs to be adjusted, the two adjacent telescopic rods 8 are pulled by manpower to make the two adjacent telescopic rods 8 relatively move and extend outward. When the support 1 reaches the specified position height, the sleeve 904 is screwed, the broken sleeve 904 moves to the direction of the deformation block 901, the extrusion groove 905 also gradually approaches and exerts the inward pressure on the deformation block 901, and the multiple deformation blocks 901 are simultaneously close to the middle, thereby clamping and locking the outer wall of the adjacent telescopic rod 8 and limiting the relative telescopic movement between the two adjacent telescopic rods 8. The locking assembly 9 can ensure that the locking between the adjacent telescopic rods 8 in the telescopic rod is more firm, and the telescopic operation is also more convenient, thereby indirectly improving the work efficiency.

[0034] It should be noted that the inner wall hole diameters of the two adjacent telescopic rods 8 are not consistent in the scheme, and their structures are similar to the existing telescopic table fishing rod. When the two adjacent telescopic rods 8 are relatively at the maximum extension amount, the inner diameter of the end of the telescopic rod 8 sleeved on the outside close to the deformation block 901 is smaller than the outer diameter of the adjacent telescopic rod 8, thereby avoiding the separation of the two adjacent telescopic rods 8 after being pulled and extended.

[0035] The above describes only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
