[0049] By rotationally connecting the connecting part 411 with the base 1, the operator rotates the locking piece 41 towards the cover plate 3, in the process of rotation, the abutting piece 421 abuts the cover plate 3, and the elastic piece is compressed under the extrusion of the cover plate 3, after reaching the locking position, under the restoring force of the first elastic piece 422, the abutting piece 421 abuts and fixes the cover plate 3 on the cavity 2; when unlocking is needed, the locking piece 41 is rotated away from the cover plate 3, so that the abutting piece 421 is separated from the cover plate 3, and the cover plate 3 can be removed by the operator, so as to take out the mobile phone screen module. Through the above arrangement, the connection structure between the cover plate 3 and the base 1 is simple, the operation steps of locking and unlocking are simple, so that the installation and disassembly of the cover plate 3 are convenient and fast, which is beneficial to improve the production efficiency.

[0050] Further, in order to improve the stability of the locking piece 41 in the process of rotation, the connecting part 411 always abuts the cavity 2 in the process of rotation, which can provide support and guiding effect for the locking piece 41, thereby improving the stability of the locking piece 41.

[0051] In order to better lock the cover plate 3, the height of the locking part 412 is greater than the height of the connecting part 411, so that after the locking piece 41 reaches the locking position, the abutting piece 421 can be close to the center of the cover plate 3, thereby making the connection between the cover plate 3 and the cavity 2 more stable.

[0052] It can be understood that, in order to avoid the cover plate 3, an avoiding groove 414 is formed between the connecting part 411 and the locking part 412, the avoiding groove 414 is used for avoiding the cover plate 3, and preventing the cover plate 3 from interfering with the rotation of the locking piece 41.

[0053] In the embodiment, the fixing jig comprises two locking mechanisms 4, one locking mechanism 4 is arranged on each side of the base 1 along the width direction of the base 1, the two locking mechanisms 4 arranged oppositely along the width direction of the base 1 can conveniently lock the cover plate 3 on the cavity 2, and the locking mechanism 4 extends along the length direction of the base 1, which can increase the contact area of the locking piece 41 with the base 1 and the cover plate 3, and further improve the locking strength. In other embodiments, the number of the locking mechanisms 4 can be adjusted adaptively according to the size of the cavity 2 and the cover plate 3, and the locking mechanism 4 can also be arranged on both sides of the base 1 along the length direction of the base 1, the locking piece 41 extends along the width direction of the base 1, which is not limited here.

[0054] During the rotation, the contact position between the abutting piece 421 and the cover plate 3 changes from abutting to the cover plate 3 to the locking piece 41 reaching the locking position, and the abutting piece 421 and the cover plate 3 are prone to wear due to extrusion and friction. In order to solve the above problems, the abutting piece 421 is a sphere, the locking portion 412 is provided with a mounting hole 413, the diameter of one end of the mounting hole 413 close to the cover plate 3 is smaller than the diameter of the abutting piece 421, the abutting piece 421 is slidingly arranged in the mounting hole 413 and can roll in the mounting hole 413, thereby reducing the wear between the abutting piece 421 and the cover plate 3.

[0055] In order to facilitate installation, the abutting assembly 42 further comprises a mounting rod 423, the mounting rod 423 is detachably connected to one end of the mounting hole 413 away from the cover plate 3, one end of the first elastic piece 422 abuts against the mounting rod 423, and the other end of the first elastic piece 422 abuts against the abutting piece 421. The abutting piece 421 and the first elastic piece 422 are sequentially put into the mounting hole 413 from one end of the mounting hole 413 away from the cover plate 3, and then the mounting rod 423 is connected to the mounting hole 413, which can conveniently realize the installation of the abutting assembly 42 and facilitate the replacement of the first elastic piece 422 and the abutting piece 421. The connection mode of the mounting rod 423 and the mounting hole 413 includes but is not limited to threaded connection or clamping, which is not limited here.

[0056] Further, a plurality of mounting holes 413 are arranged on the locking portion 412 and spaced uniformly along the length direction of the locking portion 412, each mounting hole 413 is provided with a corresponding abutting assembly 42, and the plurality of abutting assemblies 42 are uniformly and spacedly distributed along the length direction of the cover plate 3, thereby providing sufficient locking force for the cover plate 3 and balancing the stress of the cover plate 3 along the length direction of the cover plate 3.
