Connecting mechanism of supporting seat and bearing seat, side pressing tool and detection equipment

The utility model belongs to the technical field of 3C product processing, and particularly relates to a connecting mechanism of a supporting seat and a bearing seat, a side pressing tool and detection equipment. The defects of unreasonable design and the like in the prior art are overcome. The connecting mechanism for the supporting seat and the bearing seat comprises the supporting seat and a vertical bearing plate, a positioning step is arranged at the top of the supporting seat, end backward-protruding platforms are arranged at the two ends of the rear vertical face of the vertical bearing plate respectively, at least one middle backward-protruding platform is arranged in the middle of the rear vertical face of the vertical bearing plate, and the end backward-protruding platforms are arranged on the middle backward-protruding platform. The height of the end backward-protruding platform is equal to that of the middle backward-protruding platform, the end backward-protruding platform abuts against the verti
