A spring 12 is sleeved outside the fixing pin 10, and the two ends of the spring 12 are fixedly connected to the moving block 11 and the box body 9 respectively;

[0031] The fixing pin 10 is slidably connected with the box body 9 and the housing 4, the moving block 11 is slidably connected with the box body 9, and a gasket 14 is sleeved outside the bolt 6, and the gasket 14 is in contact with the bolt 6 and the housing 4;

[0032] In this embodiment, the fixing block 7, the fixing pin 10, the spring 12 and other components are designed to prevent the bolt 6 from loosening, and the fixing block 7 with multiple slots 8 on the outside is fixedly sleeved on the outside of the bolt 6. When the bolt 6 is tightened, the fixing pin 10 is inserted into one of the slots 8 on the fixing block 7, so that the fixing block 7 can be restricted from rotating at will, thereby realizing the restriction of the bolt 6. When the motor is running at high speed, the bolt 6 will not rotate loose due to shaking;

[0033] In order to achieve the purpose of moving the fixing pin 10, the device adopts the following technical solution: the other end of the fixing pin 10 is fixedly connected to a pull block 13, and the fixing pin 10 can be moved by pulling the pull block 13;

[0034] Among them, in order to accurately know whether the card slot 8 is located on the left side of the fixing pin 10, the present device adopts the following technical solution: a plurality of convex rods 15 evenly distributed in a circumferential shape are fixedly connected to the top of the bolt 6, and the plurality of convex rods 15 are respectively located directly above the plurality of card slots 8, and a convex rod 2 16 is fixedly connected to the top of the box body 9. The design of the convex rods 15 and 16 can accurately know whether the card slot 8 is located on the left side of the fixing pin 10;

[0035] In order to achieve the purpose of increasing the heat dissipation efficiency of the motor, the device is implemented by adopting the following technical solution: a plurality of heat dissipation fins 17 are fixedly connected to the outside of the casing body 1, and the heat dissipation fins 17 can increase the heat dissipation efficiency of the motor;

[0036] Among them, in order to facilitate the installation of the end cover on the casing main body 1, the present device is implemented by adopting the following technical solution: a plurality of mounting blocks 18 evenly distributed in a circular shape are fixedly sleeved on the outside of both ends of the casing main body 1, and mounting grooves are provided inside the plurality of mounting blocks 18. The design of the mounting blocks 18 and the mounting grooves can facilitate the installation of the end cover on the casing main body 1.

[0037] The use process of the utility model is as follows: when installing the motor, first put a gasket 14 on the bolt 6, and then pass the bolt 6 through the two through holes 5, the housing 4 and the mounting hole 3, and then screw the bolt 6 to install the motor in the use position, and then pull the pull block 13 when the bolt 6 passes through the two through holes 5, the housing 4 and the mounting hole 3, so that the fixing pin 10 can move to the right, and the moving block 11 can also move to the right, so that the spring 12 can be compressed, and when the bolt 6 is tightened, the pull block 13 is released, and then the fixing pin 10 will move to the left through the rebound of the spring 12, so that the left end of the fixing pin 10 will be stuck in one of the slots 8, so that the fixing block 7 can be restricted so that it cannot rotate at will, thereby realizing the restriction of the bolt 6, so that when the motor is running at high speed, the bolt 6 will not rotate and loosen due to shaking, thereby realizing the anti-loosening of the bolt 6, so that there is no need to tighten the bolt 6 manually and regularly;

[0038] Six protruding rods 15 are designed on the bolt 6, and the six protruding rods 15 are respectively located directly above the six slots 8. In this way, after the bolt 6 is tightened, it can be seen whether the protruding rod 15 on the right side is aligned with the protruding rod 2 16 on the box body 9. When aligned, one of the slots 8 on the surface fixing block 7 is located directly to the left of the fixing pin 10, so that the fixing pin 10 can just be stuck in the slot 8 when the spring 12 rebounds. When the protruding rod 15 is not aligned with the protruding rod 2 16 after tightening the bolt 6, the number of gaskets 14 can be appropriately increased to achieve the alignment of the protruding rod 15 with the protruding rod 2 16.

[0039] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the above technical solution.
