CN-224216734-U - Circuit detects frock clamp convenient to adjust

Abstract

The utility model discloses a circuit detection fixture convenient to adjust, which comprises two fixing strips, wherein the two fixing strips are rotationally connected, one ends of the two fixing strips are provided with supporting springs, a limiting mechanism is arranged in each supporting spring, one end, far away from the limiting mechanism, of one fixing strip is provided with a detection device, one side of the detection device is provided with a fixing plate, the fixing plate is provided with a limiting device, and the limiting device is matched with the detection device. Can restrict the angle of two fixed strips through adjusting the rotary disk, adapt to not unidimensional circuit detection target, can carry out good protection to detection device simultaneously, avoid detection device impaired. When the included angle of the fixing strip needs to be adjusted, the rotating disc is adjusted, and the rotating disc is in threaded connection with the fixing base and can drive the fixing base to move in the vertical direction. When unable adjustment base received the rotary disk and drove, unable adjustment base's location strip received fixedly in the spacing groove, avoided unable adjustment base to follow the rotation.
