The present application has the following effects: it is convenient to clamp and disassemble the valve core when processing the valve core.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, since the shapes of the single-hole valve cores are not exactly the same, during the positioning process, due to the different shapes, the clamping parts are also different. If it is not convenient to position it according to its shape, the valve core will shake during subsequent operation, making the positioning of the fixture unstable. Therefore, we propose a single-hole valve core positioning fixture to solve the above-mentioned problems. Utility Model Content

[0014] The utility model provides a single-hole valve core positioning fixture. Compared with the prior art, it has the following beneficial effects:

[0015] The single-hole valve core positioning fixture controls the operation of the air pump, and then the gas in the air pump enters the interior of the round tube through the air outlet pipe, the connecting pipe and the annular pipe, so that the gas moves the plug rod on the piston, thereby cooperating with the clamping block to perform positioning operations on valve cores of different shapes, making it convenient to position them during subsequent use, thereby facilitating the subsequent use process, facilitating the operation of the staff, and improving the application scope of the fixture.

[0016] At the same time, when the position of the clamp needs to be moved, the hydraulic rod is controlled to extend, and then the hydraulic rod squeezes the bottom of one end of the connecting plate, and then the rolling wheel at the bottom end of the connecting plate is sent to the outside of the shell and contacts the ground, thereby facilitating the movement of the clamp. Conversely, when the hydraulic rod contracts, the tension spring resets the rolling wheel on the connecting plate, so that the rolling wheel enters the interior of the shell, and the bottom of the shell contacts the ground, which is convenient for its placement and the clamp can be quickly switched between movement and placement, thereby improving the convenience of using the clamp.
