Seat side wall is equipped with charge and discharge gas nozzle, and inflation/deflation gonys end is communicated with first cavity, and piston is equipped with first cavity,
For the piston close to the pedestal, the piston is equipped with mandril and spring away from the pedestal one side, and the spring is around being located at
The mandril periphery, the spring other end are connected with the baffle, and the mandril other end passes through the baffle and tapered block
It is connected, the tapered block is located in second cavity, has an opening on the first connecting shaft side wall, is equipped with the opening
Job key, the job key bottom surface are bonded with the conical surface of the tapered block.
Preferably, the dowel hole is arranged in pairs with the threaded hole, and the dowel hole is shared with the threaded hole
Three pairs, it is evenly distributed on the boss.
Preferably, the dowel hole is used to install the second connecting shaft, the second connecting shaft bottom surface with the threaded hole
The positioning pin coordinated equipped with the dowel hole and the installation through-hole coordinated with the threaded hole, the second connecting shaft side is set
There is draw key.
Preferably, the piston outer periphery is cased with sealing ring.
Preferably, the charge and discharge gas nozzle is inflated by connecting air gun into first cavity.
Preferably, the ram surface scribbles lubricant.
The beneficial effects of the utility model are：Structure is reliable, it can be achieved that quick loading and unloading, pass through cylinder and the taper of activity
The design of block, the key that pushes the work forward move up and down, and so as to fulfill mechanical swelling, avoid in traditional air-expanding shaft mode folding and unfolding work
Because leaking air can not swelling outer tube phenomenon, two kinds of various sizes of connecting shafts can be also installed, realize different size sets
Loading and unloading under pipe.
