At this time, the display screen of the force sensor 7 displays the force size, and the obtained data is the locking force of the guide rail lock 4; after the data increases and reaches the locking peak value of the guide rail lock 4, the display data begins to decrease, and the locking of the guide rail lock 4 fails; the peak value of the display is the locking force finally measured by the guide rail lock 4, thereby realizing convenient batch detection of the locking effect of the guide rail lock 4, with stable structure, simple use and quick detection, which solves the problem that the existing detection device cannot detect the locking force size to verify the locking effect.

[0027] The contact position of the force sensor 7 and the sensor contact plate 6 is located at the center position of the sensor contact plate 6; when working, by setting the contact position of the force sensor 7 and the sensor contact plate 6, the force pushing the force sensor 7 to contact the sensor contact plate 6 is in a horizontal state, thereby reducing the friction between the guide rail lock 4 and the first guide rail 3, making the detection of the locking force of the guide rail lock 4 more accurate, solving the problem that the locking force of the existing guide rail lock 4 cannot meet the needs and is not accurate enough.
