Problems solved by technology

[0002] In industrial production, precision devices and machine parts are required to be faced with the problem of precision assembly of parts. The existing assembly device is to combine the positioning support and positioning support parts together and divide them into two halves. Two cylindrical pins are used to position the two halves, and The two halves are fixed by the upper and lower fixing sleeves. This structure is difficult to process and manufacture, and the assembly and disassembly of product parts is more troublesome.
