[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0030] like Figure 1-3 As shown, the utility model provides a ground wire tightening and stopping tool, including a bolt fastening part and a ground wire stopping part 421, the ground wire stopping part 421 is rotatably sleeved on the outside of the bolt fastening part, and an adaptively retractable stopper 4 is provided on the ground wire stopping part 421.

[0031] The function of the bolt fastening part is to tighten the bolt to fix the ground wire to the equipment. The function of the ground wire stopper 421 is that during the process of tightening the bolt, the stopper 4 always maintains an abutment state with the ground wire, so that the ground wire will not rotate with the bolt fastening part. Since the ground wire stopper 421 is rotatably sleeved on the bolt fastening part, the two can rotate relative to each other, and the ground wire stopper 421 will not rotate with the bolt fastening part. Then, as the bolt is screwed in, the bolt fastening part drives the ground wire stopper 421 to move axially, and through the adaptive telescopic stopper 4, the ground wire is always kept fixed by the stopper 4, and will not rotate with the bolt fastening part, thereby improving the installation efficiency and safety.

[0032] As an optional implementation, the bolt fastening portion includes a sleeve 1, the ground wire stop portion 421 includes a protective sleeve 2, a rotation groove 11 is provided on the outer wall of the sleeve 1, a rotation block 21 adapted to the rotation groove 11 is provided on the inner wall of the protective sleeve 2, and the stopper 4 is provided on the protective sleeve 2.

[0033] Furthermore, the outer wall of the sleeve 1 is recessed inward to form a circular rotating groove 11 , and the shape of the rotating block 21 is adapted to the rotating groove 11 .

[0034] Through the rotational cooperation between the rotating block 21 and the rotating groove 11 , the sleeve 1 and the protective sleeve 2 can rotate relative to each other during the rotation of the sleeve 1 , and the protective sleeve 2 will not rotate together with the sleeve 1 .

[0035] As an optional embodiment, a first mounting groove 12 for installing a bolt is provided at one end of the sleeve 1, and a second mounting groove 13 for installing a driving mechanism is provided at the other end. The first mounting groove 12 and the second mounting groove 13 are connected, and the rotating groove 11 is provided at one end of the sleeve 1 close to the second mounting groove 13.

[0036] Furthermore, the shape of the first mounting groove 12 is adapted to the nut of the bolt so that the bolt is stably fixed in the sleeve 1. Figure 2 As shown, the first mounting groove 12 adopts a hexagonal structure matched with a hexagonal nut.

[0037] The shape of the second mounting groove 13 is adapted to the output shaft of the driving mechanism, so that the output shaft of the driving mechanism is stably fixed in the sleeve 1. A connecting hole 131 may be provided on the second mounting groove 13, and a through hole 22 arranged concentrically with the connecting hole 131 is correspondingly provided on the protective sleeve 2. The connecting bolt passes through the through hole 22 and the connecting hole 131 at one time to connect with the output shaft of the driving mechanism, further improving the stability and reliability of the connection between the driving mechanism and the sleeve 1.

[0038] The specific process of the driving mechanism driving the sleeve 1 to drive the bolt to screw in or out is prior art and will not be described in detail here.

[0039] The first installation slot 12 and the second installation slot 13 are connected to each other, so as to reduce the overall weight and facilitate carrying and operation.

[0040] As an optional implementation, the stopper 4 is connected to the protective sleeve 2 through the connecting sleeve 3, and a sliding groove 31 is provided on the connecting sleeve 3. The central axis of the sliding groove 31 is arranged parallel to the central axis of the protective sleeve 2, and the stopper 4 is slidably connected to the sliding groove 31 so that the stopper 4 can slide back and forth along the radial direction of the ground wire.

[0041] As an optional embodiment, the stop member 4 includes a sliding rod 41, a stop block 42 and a spring 43. The sliding rod 41 is slidably connected to the sliding groove 31. The stop block 42 is arranged at one end of the sliding rod 41 close to the first mounting groove 12. One end of the spring 43 is connected to the stop block 42, and the other end is connected to the inner wall of the sliding groove 31.

[0042] As an optional implementation, it further includes a limiting member 5 , which is sleeved on the protective sleeve 2 and located above the connecting sleeve 3 , and is used to limit the movement of the sliding rod 41 .

[0043] The sleeve 1 drives the bolt through the connecting piece of the ground wire and is inserted into the mounting hole of the equipment. The stop block 42 can contact the ground wire on the equipment. Then, as the bolt is screwed in, the sleeve 1 drives the protective cover 2 to move axially toward the ground wire, and the sliding groove 31 slides downward along the sliding rod 41 until the sliding rod 41 contacts the limiter 5, further compressing the compression spring 43 to increase the pressure between the stop block 42 and the ground wire and increase the friction force, so that the stop block 42 and the ground wire are always in close contact, thereby fixing the ground wire.

[0044] As an optional implementation, the stopper portion 421 of the stopper block 42 is a hemispherical structure, which can increase the friction between the stopper block 42 and the ground wire when the stopper block 42 contacts the ground wire, thereby improving the stopping effect on the ground wire. At the same time, the hemispherical structure can also reduce the wear on the ground wire.

[0045] The specifications of the stop block 42 can be set according to usage requirements to achieve the stopping of ground wires of different specifications.

[0046] As an optional embodiment, the stopper 42 includes a polyurethane stopper 42 .

[0047] The polyurethane material has good wear resistance, impact resistance and elasticity, so that after the stop block 42 contacts the ground wire, it can fit tightly on the surface of the ground wire, increase the friction between the two, and ensure the stable fixation of the ground wire.
