[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model utilizes a rotating block to rotate a waterproof lead screw, which in turn causes the waterproof moving blocks on both sides to retract inward within a rectangular groove. As the waterproof moving blocks retract inward, they also cause the waterproof connecting block to move inward. When the waterproof connecting block moves inward, it causes the waterproof telescopic rod to push the waterproof transmission block. When the waterproof transmission block is pushed, it drives the waterproof flexible arc block. When the waterproof flexible arc block is pushed, the waterproof air cushion on the outer surface of the waterproof flexible arc block flexibly clamps the electronic appliances.

When the water is transported to the connecting pipe, the nozzle will spray the water evenly into the electronic appliances. Compared with traditional devices, this device can more realistically simulate these complex rain scenarios with a wider coverage area, thereby comprehensively testing the waterproof performance of the product. It can also enter these potential weak areas from various possible directions. Attached Figure Description
