The oblique tongue seat and the square tongue seat are fixedly installed on the lock body installation bracket. The oblique tongue driving motor is arranged on the back of the oblique tongue seat, and the square tongue driving motor is arranged on the back of the square tongue seat. The oblique tongue detection device is arranged at the front end of the oblique tongue seat, and the square tongue detection device is arranged at the front end of the square tongue seat. The oblique tongue seat includes an oblique tongue bearing seat and an oblique tongue fixing seat. The oblique tongue driving motor is connected to the oblique tongue bearing seat, and the oblique tongue bearing seat is fixedly installed on the lock body installation bracket through the oblique tongue fixing seat. The square tongue seat includes a square tongue bearing seat and a square tongue fixing seat. The square tongue driving motor is connected to the square tongue bearing seat, and the square tongue bearing seat is fixedly installed on the lock body installation bracket through the square tongue fixing seat. Two sliding grooves, an upper opening, and a lower opening are provided on the lock body installation bracket. The oblique tongue fixing seat and the square tongue fixing seat can slide up and down through the two sliding grooves. The oblique tongue bearing seat is placed in the upper opening, and the square tongue bearing seat is placed in the lower opening. The oblique tongue bearing seat includes a bearing and a square bar 3. The square bar passes through the middle of the bearing and rotates with the bearing. One end of the square bar is used to connect the lock body, and the other end is connected to the oblique tongue driving motor. The square tongue bearing seat includes a bearing and a gourd core 4. The gourd core passes through the middle of the bearing and rotates with the bearing. One end of the gourd core is used to connect the lock body, and the other end is connected to the square tongue driving motor. The oblique tongue detection device includes a cam 5 and a cam driving motor. A front opening is provided at the front end of the lock body installation bracket. The cam is arranged in the front opening, and the cam driving motor drives the cam to rotate in the front opening. The square tongue detection device 6 includes a rubber outer sleeve 2003, a cylinder 2001, and an elastic member 2002. The cylinder and the elastic member are wrapped in the rubber outer sleeve, and the elastic member is arranged in the cavity between the cylinder and the rubber outer sleeve. Both the oblique tongue fixing seat and the square tongue fixing seat include a front baffle 2 and a rear baffle. The front baffle and the rear baffle are connected by bolts, and a pointer portion 1001 is arranged at the front end of the front baffle. A scale 1002 for marking scales is provided on the lock body installation frame. The pointer portion points to the scale, which can facilitate the operator to quickly and accurately adjust the distance between the oblique tongue seat and the square tongue seat.

[0023] During the actual use process, the following detection processes are included:

[0024] The door handle torque test: The lock body is installed on the lock body installation bracket through the square bar and the gourd core. The oblique tongue driving motor drives the square bar to rotate. When rotating, it drives the oblique tongue to contract or pop out. During the rotation process, the oblique tongue driving motor will detect whether its maximum torque meets the standard, and after multiple rotations, as the torsion spring inside the lock body fatigues, the corresponding torque change.

[0025] Test of the number of times of the inclined tongue's elastic reset. The number of times of the inclined tongue's elastic reset mainly depends on the spring life of the inclined tongue push rod and the mechanical strength of the inclined tongue. By setting a cam at the front end of the inclined tongue seat, a cam-driven motor drives the cam to rotate. The two convex ends of the cam continuously press down the inclined tongue elastically in a repeated cycle. When the cam rotates one week, the inclined tongue is pressed down and reset twice. The cam-driven motor records the number of rotation turns to obtain the number of times of the inclined tongue's elastic reset.

[0026] Test of the compressive push-out force of the square tongue. The main content of this test is to check whether the square tongue will be pushed back by an external force when it is extruded and pushed out by an external force, resulting in the failure of the locking tongue, and to test whether the maximum extrusion force that can cause the failure of the locking tongue meets the standard. When the gourd core rotates in the gourd hole of the lock body, it will drive the square tongue to be pushed out or retracted. By controlling the push-out distance of the air cylinder, the elastic force of the elastic member is changed. When the gourd core drives the square tongue to be pushed out, the square tongue will abut against the rubber outer sleeve on the surface of the elastic member. By checking whether the square tongue can be smoothly pushed out, the compressive push-out force of the square tongue is obtained.

[0027] Test of the number of times of using the square tongue. Then, by continuously and repeatedly rotating the gourd core forward and backward, the square tongue is driven to be repeatedly pushed out and retracted to test its limit number of times.

[0028] Through the above tests, the quality of the lock body can be comprehensively detected. The test process is digital and visual, providing technical support for the inspection unit and indicating the direction for the manufacturer to improve the product quality.

[0029] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
