[0033] The detection component 11 includes a detection pin 111, a first support 112 and a first base 113. The first support 112 and the first base 113 are installed on the workbench 200. The detection pin 111 is movably set on the first support 112. The detection pin 111 is used to detect the hole position of the assembly hole 101.
