DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the utility model will become clearer. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0024] like Figures 1 to 3As shown, an embodiment of the utility model provides a pulling positioner, including: a pulling rod 1; an impact hammer 2, which is slidably sleeved on the pulling rod 1; a pulling handle 3, which is arranged at one end of the pulling rod 1; and a positioner 4, which is detachably locked to the other end of the pulling rod 1. When the above-mentioned positioner 4 is used, the positioner 4 can be aligned and placed on the pre-buried nylon sleeve, and then the impact hammer 2 can be manually slid up and down. When inserting the positioner 4, the impact hammer 2 can be controlled to move downward repeatedly on the pulling rod 1, and continuously collide and impact the positioner 4, and use the downward impact force to quickly insert the positioner 4 into the nylon sleeve. When removing the positioner 4, the impact hammer 2 can be controlled to move upward repeatedly on the pulling rod 1, and continuously collide and impact the pulling handle 3, and use the upward impact force to quickly remove the positioner 4 from the nylon sleeve; thereby achieving the advantages of easy insertion or removal of the positioner 4 and convenient operation.

[0025] The pulling rod 1 and the pulling handle 3 are detachably connected by threads.

[0026] The pulling handle 3 includes a cylinder seat 31 and an insertion shaft 32. The insertion shaft 32 is laterally inserted into the upper end of the cylinder seat 31. Through the setting of the above-mentioned cylinder seat 31, it is convenient to collide with the limit when the impact hammer 2 moves upward; through the setting of the insertion shaft 32, it is convenient to hold the pulling handle 3 by hand when the pulling rod 1 is threadedly connected with the positioner 4.

[0027] The impact hammer 2 is a cylindrical structure, and the outer circumference of the cylindrical structure is a curved surface, which is convenient for the hand to hold and slide up and down under the guidance of the pulling rod 1.

[0028] The pull rod 1 and the positioner 4 are detachably connected by threads.

[0029] The positioner 4 includes a conical connection part 41 and a positioning part 42; the conical connection part 41 is provided with a connecting threaded hole 43 in the axial direction, and the lower end of the conical connection part 41 is integrally formed with the positioning part 42. The positioning part 42 includes a cylindrical sleeve 421 and a positioning convex ring 422. The outer part of the cylindrical sleeve 421 is evenly sleeved with two circular positioning convex rings 422, and the positioning convex rings 422 can be inserted and positioned in cooperation with the inner wall of the nylon sleeve.

[0030] It also includes a locking ring 5, which is arranged below the positioning protruding ring 422. The locking ring 5 also includes two symmetrically opened clamping planes 51. When the positioner 4 and the pulling rod 1 are disassembled, the two clamping planes 51 can be clamped by a wrench to achieve rapid disassembly of the positioner 4 and the pulling rod 1.

[0031] The diameter of the locking ring 5 is smaller than the diameter of the positioning protruding ring 422 , so that no interference will occur when the positioning protruding ring 422 and the nylon sleeve are abutted and positioned.

[0032] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
