In order to reduce the contact wear on support piston and ground, the bottom of described support piston is hemisphere.
The ingress of described liquid supplying passage is by forming from the internal thread locking groove and the conical butt groove that set gradually outside to inside, and described damping channel opening device is comprised of the socket head screw of being located at the steel ball in the conical butt groove and be connected in the internal thread locking groove.
Being connected of described support piston and support piston active chamber is provided with seal arrangement between the wall.
The quantity of described support piston active chamber is that three and each support piston active chamber are evenly laid around the center line of lower threaded connection hole.
For the ease of rotation pressure ring nut, the peripheral part of described pressure ring nut is the spline dentation.
Compared to prior art, the utility model has the advantage of: the utility model not only can be realized differential adjusting and unsteady leveling function to each leg of LED detection and location equipment, thereby each leg that makes LED detection and location equipment can be regulated length and contact with ground fully, guarantee that LED detection and location equipment is placed steadily, isostasy, and has an absorbing vibration function, can reduce external shock to the impact that LED detection and location equipment produces, guarantee that LED detection and location equipment is working properly stable.
