The clamping plate 915 is stressed and the spring 913 is compressed, which can relieve a certain extrusion force and avoid directly squeezing and crushing the electrical appliance shell; an extension bar 916 is fixedly installed on one end of the extension rod 914 away from the clamping plate 915, and both ends of the extension bar 916 pass through the strip-shaped opening 912 and extend to the outside of the clamping rack 907, so as to ensure that the extension rod 914 will not separate from the end of the clamping rack 907.

[0050] The working principle of the present invention is:

[0051] When in use, the motor B410 drives the screw rod 408 to rotate. Two opposite thread grooves are provided on the outer side of the screw rod 408. The screw rod 408 can control the two screw rod sleeves 407 to move closer to each other, and then the angle of the cross rod 406 will become smaller. The other end of the cross rod 406 slides on the slide rod 404 through the slide sleeve 405, and then the cross rod 406 will push the slider 402 to slide forward in the slide rail 401, so that the entire installation platform 600 will be pushed out, and then the electrical appliance to be detected in the auxiliary mechanism 1000 can be installed;

[0052] When installing an electrical appliance, the motor 905 is controlled to rotate with the bevel gear 904, and the bevel gear 904 drives the disc 902 to rotate. The spiral tooth grooves 906 on the surface of the turntable 902 mesh with the clamping rack 907, and the turntable 902 drives the four clamping racks 907 to move closer to each other, and the clamping plate 915 at the head of the clamping rack 907 will abut against the outer wall of the electrical appliance to lock the bottom of the electrical appliance; then the bow rod 1003 with the silicone pad 1004 abuts against the upper part of the outer wall of the electrical appliance, and the contraction performance of the pneumatic telescopic rod 1006 is used to make the spring telescopic rod 1002 push the bow rod 1003 downward all the time to ensure that the upper part of the electrical appliance is firmly fixed, thereby achieving the purpose of fixing the electrical appliance to be tested;

[0053] Then, on the contrary, the motor B410 drives the screw rod 408 to reverse, so as to control the entire installation platform 600 to move back into the interior of the upper cabinet 100;

[0054] Then, the electric push rod 507 is used to push the driving rack 505 to slide back and forth in the guide rail 506, and then the driving rack 505 drives the driving gear 504 to rotate back and forth. The driving gear 504 that rotates back and forth can drive the curved pipe 501 to rotate back and forth by 0-180 degrees. The liquid is sprayed on the outer wall of the electrical appliance to be tested through the water nozzle 502 at the bottom of the curved pipe 501, thereby simulating the rain scene, which is more suitable for the detection of electrical appliances.

[0055] The fallen water is processed by the filter plate 302 and then collected in the water pool 301. The water is pumped away again by the water pump 303 and then sprayed on the electrical appliance by the curved pipe 501 and the water nozzle 502, so that the waterproof performance of the electrical appliance can be tested.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
