Sliding sleeve is welded with fixed block close to the side of bellows, and one end of fixed block is rotatably connected to limiting device, limit
Position device includes fixing pipe, and the inside of fixing pipe slidably connects telescopic rod, and the outer sheath of bellows is equipped with protecting tube, protection
Four groups of metallic rods are welded on the outside of pipe, the outside of metallic rod is arranged with two groups of metal sleeves, and the side of metal sleeve point
It is not weldingly connected with one end of telescopic rod, the top of metallic rod is welded with anti-dropout plate, and the diameter of anti-dropout plate is greater than gold
Belong to the internal diameter of casing.
Preferably, the outer sheath of the telescopic rod is equipped with second spring, and the other end of second spring is welded with connecting plate, and
The diameter of connecting plate is greater than the opening diameter of fixing pipe, and the both ends of second spring are welded with connecting plate and the inner wall of fixing pipe respectively
It is connected.
Preferably, the outer sheath of the fixed link be equipped with two group of first spring, and the both ends of the first spring respectively with fixation
