[0026] ​​​​If the glass sheet 4 needs to be removed, the annular cover is rotated off, and the glass sheet 4 can be directly taken out, and the glass sheet is conveniently removed. When the glass sheet 4 is installed, the rubber sleeve 3 is wrapped on the glass sheet 4, and then is placed in the glass mounting hole, and finally the annular cover is rotated to clamp the annular cover, so that the movable sleeve is rotated to the clamping position, and the installation of the glass sheet is completed. The fixed sleeve 2 is integrally formed with the movement core housing 1.

[0027] In some embodiments, a plurality of first clamping blocks 8 are arranged on the inner side wall of the movable sleeve 6, a plurality of second clamping blocks 9 are arranged on the outer side wall of the fixed sleeve 2, the upper end surface of the first clamping block 8 is provided with an inclined clamping portion 10, the inclined clamping portion 10 is arranged in the clockwise circumferential direction of the movable sleeve 6, the first clamping block 8 can be rotated to below the second clamping block 9 with the rotation of the movable sleeve 6, and when the inclined clamping portion 10 of the first clamping block 8 abuts against the lower end surface of the second clamping block 9, the movable sleeve 6 reaches the clamping position.

[0028] The embodiment discloses a specific structure of clamping of the movable sleeve 6 and the fixed sleeve 2. When the annular cover is installed, the first clamping block 8 and the second clamping block 9 are first staggered, and then the annular cover is rotated. With the rotation of the annular cover, the first clamping block 8 is rotated to the second clamping block 9, the inclined clamping portion 10 of the first clamping block 8 abuts against the lower end surface of the second clamping block 9, the movable sleeve 6 reaches the clamping position, the pressing portion 7 generates pressure on the rubber sleeve 3, and the glass sheet 4 is fixed. If it is desired to increase the pressure on the rubber sleeve 3, the annular cover can be continuously rotated, the inclined clamping portion 10 will continue to move the annular cover downward, and the pressing portion 7 will press the rubber sleeve 3 with greater pressure.
