[0002] In the consumer electronics and automotive electronics manufacturing industries, some product structures involve the assembly and fastening of an upper and lower shell. During assembly, the upper shell needs to be tilted and inserted into the clips on one side of the lower shell, and then the clip area on the other side is pressed to assemble the upper shell into the lower shell. This assembly process usually involves the use of specialized equipment.
