[0027] Through the pulling block 6, the protective cloth 4 is driven to move along the inner side of the protective frame until the pulling block 6 is located at the bottom of the protective frame. As the protective cloth 4 is extended, the rotating rod 701 is driven to rotate, so that the synchronous wheel 704 rotates synchronously, driving the synchronous belt 703 to transmit. At this time, the moving block 707 moves upward with the transmission of the synchronous belt 703, so that the reset spring 709 is stretched and lengthened along the guide rod 708.

[0029] Under the action of the synchronous belt 703, the synchronous wheel 2 705 is driven to rotate, so that the connecting rod 808 and the gear 809 rotate synchronously. Since the gear 809 and the rack 810 are meshed, the rack 810 is driven to move inside the body 1, so that the front end of the push rod 807 moves inside the movable frame 806 until the front end of the push rod 807 conflicts with the inner side of the movable frame 806.

During the recovery process of the protective cloth 4, the movable plate 801 is driven to move back to the inside of the main body 1, which can facilitate the limiting block to move out of the inside of the main body 1 and just limit the movement of the pulling block 6. At the same time, when the protective cloth 4 is not in use, the limiting block is stored in the inside of the main body 1 to reduce space occupancy and is more convenient.

[0030] Working principle: When in use, if the wireless radio frequency tester is in the placed state, the protective cloth 4 is driven to move along the inner side of the protective frame through the pulling block 6 until the pulling block 6 is located at the bottom of the protective frame. As the protective cloth 4 extends, the rotating rod 701 is driven to rotate, so that the synchronous wheel 704 rotates synchronously, driving the synchronous belt 703 to transmit. At this time, the moving block 707 moves upward with the transmission of the synchronous belt 703, so that the reset spring 709 stretches and lengthens along the guide rod 708. Conversely, the pulling block 6 is released, and under the action of the reset spring 709, the moving block 707 moves downward along the guide rod 708, and the conveyor belt drives the synchronous wheel 1 704 and the rotating rod 1 701 to rotate in the opposite direction, so that the protective cloth 4 is re-stored to the inner side of the protective frame; in addition, under the action of the synchronous belt 703, the synchronous wheel 2 705 is driven to rotate, so that the connecting rod 808 and the gear 809 are synchronously rotated.

The pull block 6 moves downward and conflicts with the top inclined surface of the limit plate 804, so that the movable plate 803 moves at the top of the movable plate 801 until the pull block 6 is stuck to the inner side of the limit plate 804 under the action of the compression spring 805. At this time, the pull block 6 is just located at the bottom of the guide frame 3. On the contrary, the limit plate 804 is pulled outward so that the limit plate 804 is away from the pull block 6.
