Furthermore, a guide hole is formed at the inlet of the internal thread hole.

Further, the guiding hole is a frustum-shaped hole.

Further, the central axis of the accommodating hole is perpendicular to the central axis of the internal thread hole.

Further, the shim is composed of a plurality of shims stacked.

Furthermore, the end face of the first end is provided with a mounting hole for the connecting end of the electric screwdriver to extend into, and the mounting hole is arranged at a distance from the accommodating hole and the internal thread hole; and a through connecting hole is formed in the side part of the mounting hole, and a pin is arranged in the connecting hole to be in locking connection with the connecting end of the electric screwdriver and the first end.

Further, the cross section of the mounting hole is polygonal.

Furthermore, a clamping groove for clamping the clamping end of the electric screwdriver is formed in the side face of the first end.

Furthermore, the connecting hole is arranged in the clamping groove.

Further, the clamping groove is an arc-shaped groove which is arranged around the axial direction of the sleeve body.

The invention has the beneficial effects that: according to the sleeve structure, the first end of the sleeve body is connected with the screwdriver, the second end of the sleeve body is matched with the stud to be locked through the thread between the internal thread hole and the stud to fix the stud, and then the stud is locked and fixed at the designated position through the sleeve body. In addition, the gasket arranged at one end of the internal thread hole reduces the abrasion of the stud to the sleeve body, and the service life of the sleeve body can be prolonged; meanwhile, the number of turns of the stud lock pair can be adjusted by adjusting the thickness of the gasket, so that the stud lock pair with different degrees can be realized.

[ detailed description ] embodiments

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 5, a sleeve structure for locking a stud 100 includes a sleeve body 10, the sleeve body 10 having a first end 11 and a second end 12 opposite to each other; the first end 11 is connected with the electric screwdriver; the second end 12 is provided with an internal threaded hole 121, and the internal threaded hole 121 can be in threaded fit with the stud 100; the side of the sleeve body 10 is provided with a containing hole 13, and the containing hole 13 is communicated with the internal thread hole 121; the receiving hole 13 is provided with a gasket 20.

To ensure that the stud 100 can smoothly enter the internally threaded hole 121, a hole-enlarging process may be performed at the entrance of the internally threaded hole 121 to form a guide hole 122 for guiding the stud 100 to enter. The pilot hole 122 is preferably a frustoconical hole.

In the sleeve structure, the gasket 20 is arranged at one end of the internal threaded hole 121, so that the end part of the fastened stud 100 is separated from the sleeve body 10, the degree of abrasion of the sleeve body 10 is greatly reduced, and the service life of the sleeve body 100 is prolonged. In the sleeve structure, the center axis of the receiving hole 13 is preferably perpendicular to the center axis of the female screw hole 121. In addition, the shim 20 in the accommodating hole 13 can be formed by overlapping a plurality of shims, so that the thickness of the shim 20 can be adjusted by adjusting the number of the shims, and further the number of locking turns of the stud 100 can be adjusted, so that the stud 100 can be locked in different degrees.

In the sleeve structure, the end face of the first end 11 is provided with a mounting hole 111 into which the connecting end of the power supply batch extends, and the mounting hole 111 is separated from the accommodating hole 13 and the internal thread hole 121; the side of the mounting hole 111 is provided with a through connection hole 112, and a pin is arranged in the connection hole 112 to lock and connect the connection end of the screwdriver and the first end 11 of the sleeve body 10. Preferably, the mounting hole 111 has a polygonal cross-section to facilitate positioning of the connection end of the electric screwdriver while preventing the connection end of the electric screwdriver from rotating with respect to the sleeve body 10.

In order to further ensure the stable connection between the screwdriver bit and the sleeve body 10, a clamping groove 113 for clamping the clamping end of the screwdriver bit can be formed on the side surface of the first end 11. The catching groove 113 is preferably an arc-shaped groove provided around the axial direction of the sleeve body 10. Further, each connection hole 112 of the first end 11 is opened in the card slot 113.

When the sleeve structure is used, the first end 11 of the sleeve body 10 is connected with an electric screwdriver, the second end 12 is in threaded fit with a stud 100 to be locked through the internal threaded hole 121 to fix the stud 100, and then the stud 100 is locked at a specified position through the sleeve body 10. The sleeve is simple in structure and convenient to use. In addition, the gasket 20 arranged at one end of the internal thread hole 121 reduces the abrasion of the stud 100 to the sleeve body 10, and the service life of the sleeve body 10 can be prolonged; meanwhile, the number of locking turns of the stud 100 can be adjusted by adjusting the thickness of the shim 20, so that locking of the stud 100 in different degrees is realized.

The technical principles of the present invention have been described above in connection with specific embodiments, which are intended to explain the principles of the present invention and should not be construed as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
