The locking bolt 31 is movably inserted into the mounting seat 1, and the inner ends of adjacent locking bolts 31 are connected by threads with a limiting clamping block 32, and the upper end of the limiting clamping block 32 is provided with an inclined surface inclined inwardly and downwardly, and the minimum annular diameter formed by adjacent limiting clamping blocks 32 is smaller than the diameter of the lower end of the protective cover 2. A clamping guide sleeve 33 is fixedly installed on the inner side surface of the mounting seat 1 relative to the inner and outer positions of the locking bolts 31, and a clamping groove is opened in the inner side of the clamping guide sleeve 33 in an annular shape, and the clamping groove can facilitate the clamping connection between the clamping guide sleeve 33 and the locking bolt 31, and the limiting clamping block 32 is clamped on the clamping guide sleeve 33, and a reset spring 34 is provided between the limiting clamping block 32 and the mounting seat 1, and the reset spring 34 is movably sleeved on the locking bolt 31. Through the threaded connection between the limit block 32 and the locking bolt 31, after providing a pushing force from the inside to the outside to the limit block 32, the reset spring 34 can be compressed and the locking bolt 31 can move from the inside to the outside; and through the elastic reset action of the reset spring 34, the distance between adjacent limit blocks 32 is reduced.
