Detailed ways

In order to fully understand the purpose, features and effects of the present utility model, the present utility model will be described in detail through the following specific embodiments in conjunction with the attached drawings, as follows:

As shown in Figure 2, Figure 3 and Figure 4, the preferred embodiment of the locking assembly of the present invention includes: a locking unit 1, the locking unit 1 is provided with a force-bearing part 11, and is connected to the The locking part 12 at one end of the force part 11, the end surface of the other end of the force receiving part 11 is provided with a screwdriver groove 111 for tool coupling such as a screwdriver, so that the locking unit 1 can be rotated by a screwdriver, and the locking part 12 has at least The external thread section 121 is used to lock the screw hole of the object; and the sleeve 2, which can be a hollow cylinder, is provided with a through hole 21 in the center, and is provided with the external thread section in the through hole 21. 121 and internal thread segments 22 screwed together to form the locking assembly of the present utility model.

A preferred embodiment of the locking assembly of the present utility model further includes: as shown in FIG. The near end is used to lock the screw hole in the object. The force-receiving part 11 of the locking unit 1 can be axially provided with a surrounding sleeve cover 13, so that the end of the sleeve cover 13 is fastened to one end of the sleeve 2; In an embodiment, a first fastening portion 14 may be provided on the end face of the cover 13 adjacent to the sleeve 2, and a joint with the first fastening portion 14 may be provided on the end of the sleeve 2 adjacent to the cover 13. The interfering second fastening portion 23 can prevent the sleeve 2 from being disengaged from the locking unit 1 .
