For example, air conditioning, multimedia, and window lifting can be controlled by buttons. However, the service life of buttons is limited. After being pressed many times, the buttons may fail, the buttons may be slow, or the buttons may not be pressed. Therefore, during the production process of buttons, the service life of the buttons needs to be tested.

[0003] However, there are also some problems in the use of existing key life detection devices. For example, the most commonly used one on the market is a four-bit detection, which can detect 4 keys at the same time. Therefore, the keys are clamped and fixed by turning the screws one by one for detection. In this process, the keys need to be fixed and released one by one, which is very time-consuming and labor-intensive, and affects the detection speed of the keys. Summary of the invention

[0025] When it is necessary to test the switch buttons, the four switch buttons to be tested are placed on the testing workbench 1 (placed below the pressing plate 3) in sequence, and then the rotating screw 501 is rotated. Because the rotating screw 501 is connected to the fixing plate 4 through the threaded hole opened on the fixing plate 4, and the rotating screw 501 and the pushing plate 502 form a rotating mechanism through the bearing installed on the pushing plate 502, therefore, as the rotating screw 501 rotates, the position of the pushing plate 502 can be changed, that is, the pushing plate 502 starts to move towards the direction close to the switch button under the limiting action of the limiting slider 503, and the limiting slider 503 is symmetrically arranged with two sides about the center of the pushing plate 502, which can realize Now, the left and right sides of the push plate 502 are stably supported, that is, the movement of the push plate 502 is not affected while the push plate 502 is supported, until the adjustment component 6 installed on the push plate 502 is tightly fitted with the switch button (the fitting plate 603 constituting the adjustment component 6 is tightly fitted with the switch button), and then the lifting device can start to work (the lifting device can be set as a component such as a hydraulic telescopic rod or an electric telescopic rod that can drive the lifting plate 2 to move up and down), and then the lifting plate 2 can be driven to move downward until the pressing plate 3 installed at the lower end of the lifting plate 2 contacts the switch button and presses the switch button, so that the pressing plate 3 moves up and down multiple times to press, and the service life of the switch button can be detected;

[0026] The adjusting assembly 6 is arranged on the clamping assembly 5; the adjusting assembly 6 is composed of an adjusting screw 601, a limiting plate 602, a bonding plate 603 and a guide rod 604; the adjusting screw 601 is connected to the pushing plate 502 through a threaded hole provided on the pushing plate 502, and the limiting plate 602 forms a rotating mechanism with the adjusting screw 601 through a bearing installed on its upper end, and the guide rod 604 forms a sliding connection with the pushing plate 502 through a through groove provided on the pushing plate 502; the guide rod 604 is symmetrically arranged on the left and right sides of the limiting plate 602, and the bonding plate 603 is installed on the limiting plate 602, and the outer surface of the bonding plate 603 is set to a rough surface;

[0027] When it is necessary to test switch buttons of different sizes (the switch button includes a button base at the lower end and a button panel at the upper end), the adjusting screw 601 is rotated at this time. Because the adjusting screw 601 and the limiting plate 602 form a rotating mechanism through the bearing installed on the limiting plate 602, and the adjusting screw 601 is connected to the pushing plate 502 through the threaded hole opened on the pushing plate 502, as the adjusting screw 601 rotates, the limiting plate 602 begins to move away from the pushing plate 502 under the action of the guide rod 604, because the guide rod 604 There are two symmetrically arranged around the center of the limiting plate 602, and the left and right sides of the limiting plate 602 can be stably supported and limited by the guide rod 604 until the bonding plate 603 set on the limiting plate 602 is in contact with the base of the switch button. At this time, the bases of switch buttons of different sizes can be clamped and fixed to avoid the movement of the switch button during subsequent detection. The surface of the bonding plate 603 is set to a rough surface, which can effectively increase the friction between the bonding plate 603 and the switch button base, thereby preventing the switch button from moving.
