Problems solved by technology

However, when the slider needs to be pulled, the fixing box and the movable sliding cover can only be separated from each other and the slider can be pulled by breaking the fold of the safety locking piece to destroy its structure. Therefore, the device can only be used once. high cost and low efficiency
