- The main body has a through valve hole and an air supply hole disposed between two ends of the valve hole.
- The annular first connecting mouth has a first mouth hole for receiving a valve to be inflated.
- The valve plug is disposed in the main body. The first connecting mouth is located in the valve plug. The valve plug is axially movable between a first position and a second position of the valve hole. One end of the valve plug is provided with a plurality of clamping claws. The other end of the valve plug is formed with a closed press portion. The interior of the valve plug is formed with a flow passage to communicate with an outer annular wall of the valve plug. A plurality of restraint grooves are formed in between the clamping claws and arranged in a circle to define a restraint hole. The restraint hole and the valve hole are coaxial. The restraint hole is able to contract radially. The outer wall of each clamping claw is formed with a curved portion which is enlarged radially. The restraint hole is for the first connecting mouth to be inserted axially. When the first valve is inserted into the first connecting mouth, the valve plug is moved to the first position and the press portion extends out of the valve hole. The valve hole compresses the clamping claws. Through the guide of the curved portions of the clamping claws, the restraint hole is to clamp the first connecting mouth radially. The air supply hole is in communication with the interior of the valve plug, the flow passage, and the first mouth hole, so that the first valve can be pumped.
- Accordingly, the present invention has the following inventiveness.
- 1. When the present invention is used to pump air, the user can operate the main body with one hand easily. Compared to the prior art operated with both hands, the present invention can be operated more conveniently to save time and labor.
- 2. The clamping claws of the present invention directly compress the connecting mouth to deform radially so as to tighten the valve. During inflation, the circumstances of air leakage can be minimized.
- 3. The present invention is only composed of four parts, namely, the main body, the first connecting mouth, the second mouth, and the valve plug. The entire structure of the present invention is more simple that the prior art.
