Tool clamp of adapter sleeve

Abstract

The utility model discloses a work fixture of an adapter sleeve, which relates to the technical field of fixtures, and comprises an L-shaped base, the inner wall of the L-shaped base is rotatably provided with a rotating cylinder penetrating through the side surface of the L-shaped base, and the end part of the rotating cylinder is fixedly provided with a positioning disc; the positioning assembly is used for clamping and fixing the adapter sleeve; the protection assembly comprises a rectangular groove formed in the outer surface of the sliding plate and a rectangular plate arranged on the inner wall of the rectangular groove in a sliding mode. According to the tool clamp of the adapter sleeve, through the arrangement of the protection assembly, in the process that the clamp rotates the rotating disc to drive the four arc-shaped positioning plates to conduct inner supporting and fixing on the inner wall of the adapter sleeve, when extrusion force reaches a certain value, a rectangular plate can make contact with a contact switch at the moment, and therefore the inner wall of the adapter sleeve is protected. And the contact switch automatically controls the alarm lamp to emit light to give an alarm to remind a person to stop rotating the rotating disc, so that the purpose of accurately controlling the clamping force is achieved, and damage to the adapter sleeve is avoided.
