Abstract
The utility model relates to a double-handle wooden clamp, which is composed of a left clamping arm, a right clamping arm, and a sliding rod, wherein the left clamping arm and the right clamping arm are respectively provided with a unidirectional fixing mechanism, and the right clamping arm is provided with a propelling locking mechanism. The left clamping arm and the right clamping arm are arranged on the sliding rod. The unidirectional fixing mechanism is composed of a fixed plate, a release buckle plate, and a locking spring. The propelling locking mechanism is composed of a propelling trigger and a propelling locking plate. When the release buckle plate is pressed, the release buckle plate and the sliding rod release the fixation. The clamping arm can move on the sliding rod. When the propelling trigger is pressed, the acting force is transferred to the right clamping arm through support points of the propelling trigger and the right clamping arm. The right clamping arm moves the distance towards the left side, and the propelling trigger can be repeatedly pressed to cause the right clamping arm to move towards the left side step by step for clamping an object. The utility model can flexibly adjust the distance between the left clamping arm and the right clamping arm and is laborsaving and timesaving to clamp the object. The left clamping arm and the right clamping arm can be arranged on the sliding rod in the reversal direction to improve a use function of the double-handle wooden clamp.
