[0006] The controllable support assembly includes a base and four legs. The base is fixed to the cover plate. A cross-shaped through hole is formed in the middle of the base. One ends of the four legs are respectively slidably engaged in the four channels of the cross-shaped through hole. A cross-shaped sliding groove is formed on the base and on the top surface of the cross-shaped through hole. An extrusion block is arranged in the middle of the cross-shaped sliding groove. Extrusion springs are arranged in the four branch grooves of the cross-shaped sliding groove. One end of each extrusion spring is fixed to the extrusion block, and the other end is connected to a stop block. Extrusion holes are formed on the cover plate and the base and above the extrusion block. A traction rope is arranged in the extrusion hole. One end of the traction rope extends out of the extrusion hole and is above the cover plate, and the other end penetrates downward into the extrusion springs respectively and is connected to the stop block;

[0007] The extrusion springs are in a compressed state in the cross-shaped sliding groove. The control assembly presses the extrusion block downward, drives the extrusion springs and the stop blocks to move downward. After disengaging from the cross-shaped sliding groove, under the elastic force of the extrusion springs, the stop blocks abut against the ends of the legs located in the cross-shaped through hole and push the legs to protrude outward.

[0008] Furthermore, a round tube is sleeved on the outer periphery of the extrusion spring, and one end of the round tube is fixedly connected to the extrusion block.

[0009] Furthermore, grooves are provided on the bottom surfaces of the four channels of the cross-shaped through hole, and a return spring is arranged in the groove. The bottom end of the return spring is fixed to the bottom surface of the groove, and the top end is against the round tube.

The top end of the support rod is hinged to the middle section of the force handle. The downward pressure rod is located above the extrusion hole and the top end is hinged to one end of the force handle.

[0011] A method for using a telescopic support cover is performed according to the following steps:

[0012] Step 1: Buckle the telescopic support cover plate on the hole to be installed, and control the support assembly to be located in the hole;

[0013] Step 2: Operate the force application handle of the control component and lift the end of the force application handle away from the lower pressure rod. Due to the principle of lever, the lower pressure rod moves downward along the extrusion hole on the cover plate to squeeze the extrusion block, driving the extrusion spring and the stopper to move downward. After leaving the cross-shaped slide groove, under the elastic force of the extrusion spring, the stopper and the end of the leg located in the cross-shaped through hole are abutted and push the leg outward. After the leg is extended, it abuts against the inner wall of the hole;

[0014] Step 3: Remove the control components to prevent obstruction of plane operation;

[0015] Step 4: After use, pull the traction rope upwards to squeeze the spring to shrink. After shrinking to a certain extent, it returns to the cross-shaped slide groove under the action of the return spring, and the legs are loosened from the inner wall of the hole without external force.

[0016] Step 5: Remove the telescopic support cover.
