A push button pin for coupling together two halves of pliers. The pin can include one or more balls elastically biased in a radially-outward direction to couple the pin to a retainer. The balls are normally pushed outward by an engagement portion, but a push button head can be pressed axially downward and cause the balls to align with a receiving portion, which allows the balls to descend into the interior of the pin. The push button is also integral with the receiving and engagement portions to better facilitate the movement of the balls and the removability of the pin. A user can therefore quickly adjust the jaw width of a pair of pliers and better utilize the pliers in the process.

The pipe pliers includes a first clamping body, a driving handle, and a clamping element. The first clamping body includes a body portion. The body portion includes two side plates and is formed with two guiding toothed grooves. A receiving groove is defined between the two side plates. Each side plate is formed with a sliding groove facing the other side plate. The driving handle is slidably arranged at the two guiding toothed grooves and is pivotable with respect to the first clamping body. The driving handle has a protrusion. The clamping element is slidably arranged at the two sliding grooves. The clamping element has a recess. The protrusion is rotatably inserted into the recess. When clamping a workpiece, the clamping element slides linearly.

The present invention relates to a hand tool. More specifically, a rapid adjust multigrip tool having a first arm, second arm, linking mechanism and locking mechanism. The first arm is connected to the second arm via a primary pivot. The linking mechanism biases the arms away from one another. The locking mechanism allows an operator to selectively secure the first and second arms together.

A hand tool provided with a first handle, a second handle, a first working portion, a second working portion and a working portion connecting mechanism. The first handle is fixedly connected to the first working portion, the second handle is pivotably connected to the second working portion, and the second working portion is connected to the first working portion through the working portion connecting mechanism, the second working portion has a first position and a second position, and the working portion connecting mechanism causes the second working portion to be moved from the first position to the second position when the second handle is moved from away from the first handle to closer to the first handle. The first position is the position where the second working portion is located away from the first working portion, and the second working portion is rotated and translated relative to the first working portion when the second working portion is in the second position. The hand tool can provide a greater clamping force, helping to further save labor.

The present invention provides an opening-closing device including a first component, a second component and a third component. The second component is rotatably connected with the first component, and the third component is rotatably connected with the second component. The present invention further includes a mode switching device for switching operating modes of the opening-closing device. The operating modes include a conventional mode and a labor-saving mode. When the opening-closing device is in the conventional mode, the third component is fixed relative to the second component. When the opening-closing device is in the labor-saving mode, the third component is rotated in the opening direction relative to the second component during opening of the opening-closing device, and the third component is rotated in the closing direction relative to the second component during closing of the opening-closing device.
