Auxiliary tool for retainer detection

The utility model discloses an auxiliary tool for detecting a retainer, which comprises a counterweight base, a screw rod arranged on the counterweight base and a pressing plate in threaded connection with the screw rod, and a space for placing the retainer is formed between the pressing plate and the counterweight base; clamping jaws are hinged to the two ends of the pressing plate and rotate towards or away from the balance weight base. Limiting blocks used for limiting rotation of the clamping jaws are further arranged at the two ends of the pressing plate. According to the technical scheme, the retainer can be reliably fixed, the structure is simple, the operation is convenient, the retainer detection efficiency is improved, and the detection cost is reduced. 本实用新型公开了一种保持架检测辅助工装，包括配重底座、设置在配重底座上的螺杆、螺纹连接在螺杆上的压板，所述压板与配重底座之间形成放置保持架的空间；所述压板的两端均铰接有卡爪，该卡爪朝向或远离配重底座转动；所述压板的两端还均设置有用于限制卡爪转动的限位块。该技术方案能够对保持架提供可靠的固定，且结构简单，操作便捷，提高了保持架检测的效率，降低了检测的成本。
