Description

Valve puller

The present invention is related to gas nozzles, in particular to a gas nozzle puller.

The air valve, also known as the air nozzle and the air nozzle, is used as the valve body of the inner tube tire, which can allow the outside air to enter and prevent the internal air from escaping the tire. In the case of normal installation, the air nozzle system normally protrudes out of the wheel frame to facilitate connection with the pumping joint, but the uninflated inner tube is not enough to support the air nozzle, so a clamping tool will be used to pull it during the installation process Pull out the air nozzle, so that the air nozzle can move upwards to firmly protrude the card against the wheel frame and then inflate. When the tire wants to replace the air nozzle, it is necessary to use the clamping tool to pull the old valve out of the wheel frame, so that the new valve can be installed later, so the clamping tool is very important for the installation and removal of the valve.

However, most replacement personnel only take pliers and other hand tools that can be clamped to carry out the drawing operation of the air nozzle, so the external thread of the air nozzle is often worn during the installation process, or it is difficult to pull out the valve. During the process, improper application of force causes the pliers to press against and hit the surface structure of the wheel frame, resulting in undue wear and tear.

Therefore, it is necessary to provide a novel and progressive valve puller to solve the above-mentioned problems.

The main purpose of the present invention is to provide a gas nozzle puller, which is a professional tool specially designed for pulling the gas nozzle, which can quickly connect the gas nozzle without damaging the thread structure of the gas nozzle, and can effectively perform the pulling operation.

To achieve the above object, the present invention provides a valve puller, comprising: a main body, at least one valve set and a supporting point mechanism. The at least one air nozzle kit is arranged on the main body to be connected with at least one air nozzle head; the fulcrum mechanism includes a connecting portion and at least one pressing block, the connecting portion is arranged on the main body, and the at least one pressing block can be replaced Connected to the connecting portion, the at least one pressing block is pressed against the wheel frame as a fulcrum so that the main body can swing relative to the wheel frame.
