The docking screw hole is opened in the middle of the inner end of the first transmission shaft, and the first limit platform is integrally formed and connected to the outer end of the first transmission shaft.

[0006] Preferably, the second transmission shaft is nested in the first through groove and the second through groove on the right side, and a docking screw and a second limit platform are provided on the second transmission shaft. The docking screw is integrally formed and connected to the middle of the inner end of the second transmission shaft, and the second limit platform is integrally formed and connected to the outer end of the second transmission shaft.

[0007] Preferably, the docking screw is threadedly connected to the docking screw hole.

[0008] Preferably, a U-shaped frame is mounted on the first transmission shaft and the second transmission shaft, and a docking square groove is integrally formed on the top of the U-shaped frame.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the top of the U-shaped frame of the utility model is integrally formed with a docking square groove, so that the U-shaped frame can be docked with the wrench; the first transmission shaft and the second transmission shaft are equipped with a U-shaped frame, and the outer sleeve and the inner sleeve can be easily driven to rotate by the U-shaped frame; based on the above, the utility model can connect two different types of sleeves together, effectively improving the convenience of using the sleeve.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1-3 As shown, a coal mine equipment maintenance wrench socket comprises an outer sleeve 1, a first hexagonal groove 2 is provided in the middle of the outer sleeve 1, a first through groove 3 and an inner sleeve 4 are provided on the first hexagonal groove 2, the first through groove 3 is symmetrically provided on both sides of the first hexagonal groove 2, the inner sleeve 4 is nested in the first hexagonal groove 2, a second hexagonal groove 5 is provided in the middle of the inner sleeve 4, second through grooves 6 are symmetrically provided on both sides of the second hexagonal groove 5, the size and position of the second through groove 6 are symmetrical with the first through groove 3, a first transmission shaft 7 is nested in the first through groove 3 and the second through groove 6 on the left side, a docking screw hole 8 and a first limit platform 9 are provided on the first transmission shaft 7, A connecting screw hole 8 is opened in the middle of the inner end of the first transmission shaft 7, and a first limit platform 9 is integrally connected to the outer end of the first transmission shaft 7. The second transmission shaft 10 is nested on the first through groove 3 and the second through groove 6 on the right side. A docking screw 11 and a second limit platform 12 are provided on the second transmission shaft 10. The docking screw 11 is integrally connected to the middle of the inner end of the second transmission shaft 10, and the second limit platform 12 is integrally connected to the outer end of the second transmission shaft 10. The docking screw 11 is threadedly connected to the docking screw hole 8. A U-shaped frame 13 is mounted on the first transmission shaft 7 and the second transmission shaft 10, and a docking square groove 14 is integrally connected to the top of the U-shaped frame 13.

[0016] Specific usage: when the first hexagonal slot 2 needs to be used, the second hexagonal slot 5 is installed on the screw rod where the nut needs to be loaded and unloaded. As the second hexagonal slot 5 moves downward and contacts the nut, the second hexagonal slot 5 is clamped on the top of the nut, and the first hexagonal slot 2 continues to move downward and is installed on the nut. Finally, the wrench is nested in the docking square slot 14, and the wrench is turned to drive the U-shaped frame 13 to rotate. The rotation of the U-shaped frame 13 drives the outer sleeve 1 and the inner sleeve 4 to rotate at the same time through the first transmission shaft 7 and the second transmission shaft 10. The rotation of the outer sleeve 1 drives the first hexagonal slot 2 to rotate to load and unload the nut.

[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
