[0008] The cam is fixed on the upper end of the hydraulic cylinder to prevent the hydraulic cylinder from sliding off and the hydraulic cylinder is fixed on the lower end of the hydraulic cylinder to move upwards to drive the hydraulic cylinder to move upwards to drive the hydraulic cylinder to move upwards.

[0009] Furthermore, the connecting rod is clamped in the circular hole of the telescopic sleeve, and the outer side of the connecting rod is clamped and fixed by a nut. The top output end of the inner gas rod is a ring-type structure, and the ring is sleeved on the outer side of the connecting rod.

[0010] Furthermore, the outer ring is a semicircular frame structure, and circular hole structures are opened on both sides of the outer ring, and the outer side of the sleeve is sleeved in the circular hole.

[0011] Furthermore, a group of outer rods are provided on both sides of the oil cylinder, and both sides of the outer rods are located on both sides of the top plate and are locked and fixed by nuts.

[0012] Furthermore, the bottom ring is a semi-ring structure consisting of two groups connected by hinges, the two groups of semi-rings are connected by bolts, and the combined fixation is achieved by nuts.

[0013] Furthermore, the size of the bottom collar is adapted to the size of the bottom end of the oil cylinder.

In its structure, the I-piece is the main pressure-bearing component, so the slider at the bottom can be used to make fine adjustments on the slide rail to meet the actual use needs on site.

[0017] 2. In this device, the sleeve-inner gas rod structure can be slightly deflected through the hinged seat structure at the bottom, and can be fixed by the bottom end of the telescopic sleeve. The extended sleeve structure can be lifted by the inner gas rod, and the locking tooling can be lifted to a certain height to achieve height control of the cylinder.

[0018] 3. In this device, by setting up a locking fixture structure, the distance between the top plate and the bottom ring can be controlled by the outer rod structure on both sides, thereby meeting the clamping requirements of cylinders of different lengths. During debugging, the nut on the outer rod can be unscrewed outward to clamp the bottom end of the cylinder on the bottom ring, and the top plate can be clamped between the outer rods on both sides and fastened by two sets of locking nuts to complete the fixation. Therefore, when the locking fixture clamps the outer sleeve of the cylinder core, the Qianjinding can push the core of the cylinder out and the cylinder can be removed.
