Affected by the operating space and product structure, the position of the product test interface is unique. When connecting, it is necessary to align along the corresponding clamping position and specific angle of the clip. The clip connection has strict requirements on the product installation orientation and installation proficiency, and the installation process is laborious and time-consuming.
