[0037] The implementation principle of this embodiment is:

[0038] The rubber spring of the mining screen is provided with a telescopic rod 2. When using the device, the staff takes out the first spring from the telescopic rod 2, and then the staff puts the first spring on the outer surface of the telescopic rod 2. Then the staff takes out the bottom plate 4 and installs the bottom plate 4 to the bottom of the telescopic rod 2. An end cover 7 is provided. At this time, the staff takes out the end cover 7 and uses a tool to screw it on the outer surface of the connecting rod 5 through the hexagonal hole 19 inside the end cover 7. Since the height of the end cover 7 is the same as the height of the mounting groove 6, the top of the bottom plate 4 can be kept flat. Then, the staff takes out the protective shell 11 and pulls the movable plate 12. At this time, the movable plate 12 will move. The movement of the movable plate 12 can drive the baffle 13 to move, and can drive the slider 14 to move. The sliding movement can drive the sliding block 15 to move. The movement of the sliding block 15 can compress the second spring 16. At this time, the staff inserts the connecting plate 23 at one end of the protective shell 11 into the connecting plate 23. Into the interior of the groove 9, when the connecting plate 23 is fully inserted, the positioning groove 24 inside the connecting plate 23 is located on one side of the baffle 13, and then the staff releases the movable plate 12. At this time, the second spring 16 will restore its deformation and can push the sliding block 15 to move. The movement of the sliding block 15 can drive the slider 14 to move. The movement of the slider 14 can drive a movable plate 12 to move. The movement of the movable plate 12 can drive the baffle 13 to move. Since the positioning groove 24 is located on one side of the baffle 13, the baffle 13 can be inserted into the positioning groove 24, so that the connecting plate 23 can be fixed, and then the protective shell 11 can be fixed. Then the staff completes the installation of the top plate 1 according to the above process, and the installation of the protective shell 11 can be completed, so that the protective shell 11 can protect the rubber spring, thereby extending the service life of the equipment. Then the staff puts it into the interior of the mine screen and uses it.
