Semi-automatic clamp device

Abstract

A semi-automatic clamp device includes a tightening mechanism and a connecting rod mechanism. The lowest side of the device is a first workbench having a baffle and supports which connect a passive connecting rod through auxiliary connecting rods. An end of the passive connecting rod connects the baffle through a first spring, and another end connects an active rocker connecting downward on the supports, with another end of the active rocker touching a slide block which connects a slide wheel through a second connecting rod. On a connection point between the second connecting rod and the slide block, the slide block connects tie plates through the first connecting rod transfixing a second workbench having a support bracket. The tie plates connect the support bracket through second springs. This clamp device realizes semi-automatic clamping, improves production efficiency significantly, clamps more securely, and decreases an error in drawing a detection conclusion effectively.
