Tool
First Claim
1. A tool comprising two handles and a tool head, wherein:
- the tool head is composed of two clamping members middle portions of which are pivotally connected on a pivot shaft, one end of each clamping member having a pivot hole for pivotally connecting with the handles; and
each handle has a pivoted end, the pivoted ends being pivotally connected with each other on a shaft, a section of each handle near the pivoted end being formed with a caved section laterally passing through the handle, the handle being divided by the caved section into two side boards, a pin being disposed between the two side boards of each handle, the pins being fitted in the pivot holes of the clamping members, whereby when the handles are pivoted relative to each other, the pivotally connected clamping members are driven and pivoted, at least one side board of one of the handles having a projecting block, while one side board of the other of the handles being formed with at least one slot cooperating with the projecting block, the slot being positioned in the moving path of the projecting block when the handles are relatively pivoted, whereby by means of cooperation between the slot and the projecting block, the pivoting range of the handles is restricted.

Abstract
A tool including two pivotally connected handles and a tool head. The tool head is composed of two clamping members which are pivotally connected. The clamping members are further pivotally connected with the handles to form a double lever structure. When the handles are relatively pivoted, the clamping members are driven and pivoted relative to each other to clamp a work piece. One of the handles has a projecting block, while the other of the handles is formed with at least one slot cooperating with the projecting block. The slot is positioned in the moving path of the projecting block when the handles are relatively pivoted. By means of cooperation between the slot and the projecting block, the pivoting angle of the handles is restricted.
