[0013] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Reference Figure 1 and Figure 2 This embodiment includes a driving assembly 1, a base plate 2, and a synchronization assembly 3. The driving assembly 1 and the synchronization assembly 3 are both installed above the base plate 2. The driving assembly 1 includes two groups of symmetrical bases 11 and a driving motor 12. The base 11 is installed on the bottom, and the driving motor 12 is installed above the base 11.

[0015] The synchronous assembly 3 includes two sets of synchronous wheels 31, a synchronous fixing block 32, a clamping rod mounting block 33 and a clamping rod 34. The synchronous wheel 31 is installed in the mounting base 11, and the synchronous wheel 31 rotates coaxially with the input shaft of the drive motor 12. A synchronous belt rotates synchronously on the two sets of synchronous wheels 31.

[0016] A plurality of guide rail sliders 21 are fixed on the bottom plate 2, the clamping rod mounting block 33 is fixedly connected to the slider on the guide rail slider 21, the synchronous fixing block 32 is mounted on the upper surface of the clamping rod mounting block 33, and the clamping rod 34 is mounted on the lower surface of the clamping rod mounting block 33. Correspondingly, the bottom plate 2 has an avoidance groove 22 for the movement of the clamping rod 34, and the synchronous fixing block 32 is fixed to the synchronous belt, so that when the synchronous belt moves, the clamping rod mounting block 33 is driven to slide on the guide rail slider 21 to drive the clamping rod 34 to move. In addition, each group of clamping rods 34 is provided with two symmetrical clamping rods 34.

[0017] The base 11 and the drive motor 12 of the same group are located on the edge farthest from each other on the bottom plate 2, and the synchronous wheel 31, the synchronous fixing block 32, the clamping rod mounting block 33 and the clamping rod 34 of the same group are located below the synchronous belt. The two groups of drive components 1 and synchronous components 3 are arranged perpendicular to each other.

[0018] In this embodiment, the drive motor 12 is a servo motor. The clamping rod 34 is wrapped with Teflon to avoid hard contact with the glass, thereby avoiding damage to the glass during the clamping process.

[0019] The two sides of the same set of synchronous belts are connected to the clamping rods 34 through the synchronous fixing blocks 32. Driven by the driving motor 12, the same set of clamping rods 34 will move toward each other, thereby clamping and positioning the glass cover of the mobile phone.
