[0023] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the following will describe the present application through specific embodiments shown in the drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. The structures, proportions, sizes, etc. shown in the drawings of the present specification are only used to cooperate with the content disclosed in the specification, to enable those skilled in the art to understand and read, and are not intended to limit the implementation conditions of the present application, so they do not have substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that the present application can produce, should still fall within the scope of the technical content disclosed by the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0024] It should be noted that, in order to avoid unnecessary details from obscuring the present application, only structures and / or processing steps closely related to the present application are shown in the drawings, and other details not closely related to the present application are omitted.

[0025] As shown in Figures 1 to 8 The present embodiment adopts the following technical solutions: a handle cover 1 is installed on the outer side of a handle 2 and is fixed by a fixed screw 1, the fixed screw 1 is an M4 screw, the inner side of the handle 2 is sleeved in the hole of a handle base 5, the inner side of the handle 2 is respectively provided with an O-ring 6 and a limiting piece 7, the limiting piece 7 is installed at the inner end of the handle 2 by a fixed screw 2, an O-ring groove is formed in the handle base 5, the O-ring 6 is arranged in the O-ring groove, the fixed screw 2 is an M4 screw, an M5 tightening screw 3 is installed in the threaded hole of the handle 2, the M5 tightening screw 3 is an M5 tightening screw, a spring 10 and a ball 9 are installed in the hole of the handle base 5 and are fixed by an M6 tightening screw 11.

[0026] The working principle of the present embodiment is as follows: in use, the handle 2 is rotated by loosening the M5 tightening screw 3 to expose the lock cover, and then the lock is opened by a key through the lock core hole exposed by the lock cover; after the lock is opened, the handle 2 is rotated again, the ball 9 on the handle 2 is clamped into the recess hole of the handle base 5 and rotated back to the middle (under the positioning action of the ball 9, the handle 2 and the handle base 5 can be accurately reset to the middle position, and the M5 tightening screw is easily positioned); then the M5 tightening screw is tightened, and the handle 2 will not be loose; the limiting piece 7 presses the elastic O-ring 6 to achieve the rotation of the handle 2, and at the same time, the handle 2 and the handle base 5 cannot have a loose virtual position; the present embodiment greatly improves the firmness of the handle of the lock, overcomes the loose structure of the handle of the lock on the market, and greatly improves the assembly efficiency of the intelligent lock through modular production and assembly.

[0027] It should be noted that, in order to avoid unnecessary details from obscuring the present application, only structures and / or processing steps closely related to the present application are shown in the drawings, and other details not closely related to the present application are omitted.
