[0002] In the industrial production process, it is often necessary to use screens to screen materials in order to obtain fine-grained materials that meet production requirements. Since the screened materials absorb moisture or carry static electricity, it is easy to cause mesh blockage, which seriously affects the screening quality. As the use time increases, the screen gradually loosens. When the screen needs to be adjusted to keep it taut again, the screen needs to be removed and then reinstalled.

[0003] For example, the application with publication number CN114308652A discloses a screen structure, including a first screen frame and a first screen arranged in the first screen frame, the screen structure also includes a second screen frame for stacking on the first screen frame and a second screen arranged in the second screen frame, the second screen frame is provided with a clamping block and a plurality of clamping members for clamping the second screen, and the plurality of clamping members are distributed in the circumferential direction of the second screen frame, and the first screen frame is provided with a clamping groove that is engaged with the clamping block. The present invention facilitates graded adjustment of the number of meshes of the screen by stacking the second screen on the first screen, and the provision of the clamping member facilitates clamping the screen body.

[0004] However, the screen structure in the application has no protective device.
