In the installation process of the bolt 4, the sliding block 43 slides to compress the spring 32 and further push the stud 42 to be close to the installation hole of the elevator shaft, when installation is not needed, the spring 32 pushes the sliding block 43 to slide in the sliding groove 31, when the spring 32 is restored to a natural state, the sliding block 43 is located at one end, close to the bolt cap 41, of the sliding groove 31, one end, provided with external threads, of the stud 42 is completely accommodated in the sleeve 3, the possibility that the external threads of the stud 42 are damaged can be reduced, and the service life of the bolt 4 is prolonged.

Referring to fig. 2, the stud 42 is rotatably connected with a connection ring 6, and the connection ring 6 is annular and is disposed coaxially with the stud 42. The connecting ring 6 is positioned on one side of the stud 42 close to the bolt cap 41, and the diameter of the connecting ring 6 is larger than that of the through hole 12, and the stud 42 can rotate in the connecting ring 6. When the workman rotated stud 42 and screwed up the mounting hole of elevartor shaft in, stud 42 drives go-between 6 and is close to sleeve 3, and when go-between 6 contradicted with sleeve 3's upper end, go-between 6 and stud 42 rotate relatively, can reduce the wearing and tearing between go-between 6 and the sleeve 3, and then reduce the wearing and tearing between bolt 4 and the sleeve 3, increase of service life.

Referring to fig. 2, an internal thread is formed in the through hole 12, the through hole 12 is connected with the fixed cylinder 2 through the internal thread, the fixed cylinder 2 is coaxial with the through hole 12, and the sleeve 3 is coaxially and rotatably connected with the fixed cylinder 2. The inner wall of the fixed cylinder 2 is provided with an annular groove, the outer wall of the sleeve 3 is fixedly connected with an annular block, and the annular block is connected in the annular groove in a sliding manner. Bolt 4 rotates and drives sleeve 3 and rotate, and then drives the annular piece and slide in the ring channel, and after bolt 4 damaged, the workman can rotate solid fixed cylinder 2, and then makes solid fixed cylinder 2 and base 1 separation, conveniently changes bolt 4.

Referring to fig. 2, a fixing nut 21 is sleeved at one end of the fixing cylinder 2 close to the body 11, and the fixing nut 21 is coaxially and fixedly connected with the fixing cylinder 2. When needs are changed solid fixed cylinder 2 and bolt 4, the workman uses the spanner to drive and fixed nut 21 cooperation rotation solid fixed cylinder 2, and then drives solid fixed cylinder 2 and base 1 separation, convenient operation, and final go-between 6 is contradicted with the upper surface of fixed nut 21, can reduce the wearing and tearing between go-between 6 and the fixed nut 21, makes things convenient for simultaneously screwing up of bolt 4.

Referring to fig. 2, a plurality of accommodating grooves 13 are formed in the upper surface of the base 1, the accommodating grooves 13 are located on one side of the through hole 12 close to the main body, and the accommodating grooves 13 are communicated with the through hole 12. The depth of the receiving groove 13 is equal to the thickness of the fixing nut 21 plus the thickness of the connecting ring 6, and one side of the receiving groove 13 away from the main body penetrates through the side wall of the base 1. Fixing nut 21 and go-between 6 can be accomodate to holding tank 13, and then can reduce the upper surface that cap 41 protrudes base 1, and cause the possibility of influence to the operation of elevator, guarantee the smooth operation of elevator, can make things convenient for the workman to put into the spanner and press from both sides tight rotation, convenient operation to fixing nut 21 in accomodating the groove simultaneously.

The implementation principle of the embodiment 1 is as follows: a worker approaches the base 1 to the wall of the elevator shaft, aligns the through hole 12 to a mounting hole of the elevator shaft, presses the bolt 4 to compress the spring 32 under force, slides the bolt 4 in the sleeve 3 to enable the bolt 4 to approach the mounting hole of the elevator shaft, rotates the bolt 4, drives the sleeve 3 to rotate in the fixed cylinder 2 by the bolt 4, and then connects the bolt 4 to the mounting hole of the elevator shaft in a threaded mode, so that the guide rail is fixed; when the bolt 4 is damaged and needs to be replaced, a worker rotates the fixing nut 21 by using a wrench to drive the fixing cylinder 2 to rotate from the through hole 12, and then separates the fixing cylinder 2 from the through hole 12, so that the bolt 4 is replaced.

Example 2

Referring to fig. 3 and 4, the present embodiment is different from embodiment 1 in the way of detaching the bolt 4. The length of the sliding groove 31 is equal to the length of the sleeve 3, and one side of the sleeve 3 close to the body 11 is provided with an internal thread. The stud 42 is sleeved with a limiting cylinder 5, the limiting cylinder 5 is located between the sliding block 43 and the connecting ring 6, an external thread is arranged on one side, close to the sliding block 43, of the limiting cylinder 5, and the limiting cylinder 5 can be connected into the sleeve 3 in a threaded mode. Spacing section of thick bamboo 5 can shelter from spout 31, and then spacing to slider 43, reduce the possibility of bolt 4 and sleeve 3 separation, after only bolt 4 damages, after the workman takes off the fixed orifices, rotate spacing section of thick bamboo 5 and make spacing section of thick bamboo 5 at sleeve 3 internal rotation, and then make spacing section of thick bamboo 5 and sleeve 3 separation, then pulling bolt 4 makes slider 43 roll-off from spout 31, and then make bolt 4 and sleeve 3 separation, and then change bolt 4 alone, can resources are saved.

Referring to fig. 4, one end of the limiting cylinder 5 close to the body 11 is coaxially and fixedly connected with a rotating nut 51, and the inner diameter of the rotating nut 51 is equal to that of the limiting cylinder 5.
