Most of the ancient earthen building sites in the northwest are rammed with silt, silty clay or sand. Because they are purely earthen buildings, they are extremely vulnerable to wind and sand. Under the influence of long-term natural and human factors, the site itself has shown different types of diseases. Especially under the action of strong winds and sand-carrying winds, the site itself has shown different degrees of damage; generally there are two types, one is a special wind erosion simulation device for earthen sites, which is the loss of earthen site particles under repeated abrasion and impact power under the action of strong winds and sand-carrying winds, and the other is a special wind erosion simulation device for earthen sites, which is caused by the loss of particles. Flaky peeling, regional collapse, and the suspension of the site itself are caused by various diseases.

[0026] The limiting screw 14 penetrates through the outer wall of the sliding base 13 and abuts against the outer wall of the slide rail 4 , so that the limiting screw 14 can limit the sliding of the sliding base 13 and maintain the stability of the sliding base 13 .

[0027] Furthermore, the clamping structure includes a slide rod 16 , a screw rod 17 , and a clamping bar 18 .
