The rotating bidirectional screw rod 503 makes the insert block 5 move laterally through the threaded cooperation with the nut seat 502. When one end of the insert block 5 is inserted into the slot on the mounting plate 303, the mounting plate 303 can be limited, thereby realizing the installation of the tester body 301.
