These include mold hardware, mechanical hardware, household hardware, display hardware, ship hardware, construction hardware, aerospace hardware, and security products. Hardware accessories also include a wide variety of bolts, nuts, washers, circlips, springs, pins, retaining rings, steel balls, runners, rivets, rivet nuts, eyelets, and other small hardware items. To ensure the quality of hardware parts and accessories, they must be inspected after processing.

[0003] For example, the Chinese patent publication number CN214980389U discloses a limit device for detecting hardware parts and accessories, comprising a base, the top of which is fixedly connected to two symmetrically arranged vertical plates; a sliding rod and a threaded rod are installed between the two vertical plates, and there are two sliding rods, the threaded rod is located between the two sliding rods, a first servo motor is fixedly installed on the side wall of one of the vertical plates, and the output end of the first servo motor is axially connected to one end of the threaded rod; a slider is threadedly sleeved on the threaded rod, the top of the slider is fixedly connected to an assembly block, a second servo motor is fixedly installed inside the assembly block, and the output end of the second servo motor is axially connected to a rotating rod. The limit device for detecting hardware parts and accessories described in this utility model can limit the position when detecting parts and accessories, and can detect multiple parts and accessories at the same time, thereby improving the efficiency of detection and bringing better prospects for use;

[0004] The technical solution recorded in this proposal first clamps the hardware parts to be inspected into the limiting cylinder, and then limits and fixes them by rotating the fasteners. However, in actual use, when performing appearance inspection on hardware parts such as bolts, part of the hardware parts are stuck in the inside of the limiting cylinder, which makes it impossible to perform appearance inspection on the part of the hardware parts stuck in the limiting cylinder. As a result, the inspection personnel need to take the hardware parts out of the limiting cylinder and reposition them, and perform appearance inspection on the part of the hardware parts originally stuck in the limiting cylinder, thereby reducing the inspection efficiency. Utility Model Content

[0005] The purpose of the present utility model is to provide a limit device for detecting hardware parts to solve the problems raised in the above background technology.
