One end of the bidirectional threaded rod 23 is fixedly connected to a handle 29, and the size of the limiting rod 28 is adapted to the size of the moving hole 27. Rotate the handle 29 to drive the bidirectional threaded rod 23 to rotate inside the connecting plate 22, and the bidirectional threaded rod 23 drives the clamping plate 24 to move, so that the staff can quickly rotate the bidirectional threaded rod 23 to adjust the position of the clamping plate 24, improving the quickness of the device.

[0030] Refer to Figure 4 and Figure 5As shown in the figure, specifically, the protection device 3 includes two sliding frames 31, both of which are fixedly connected to the surface of the protector body 1. The inner surfaces of the two sliding frames 31 are both slidably connected with sliding plates 32. One side of the two sliding plates 32 is fixedly connected with a baffle 33. The side of the sliding plate 32 away from the baffle 33 is fixedly connected with an elliptical plate 34. The surface of the elliptical plate 34 is fixedly connected with a mounting block 38. A screw rod 35 is inserted into the mounting block 38 in a threaded manner. One end of the screw rod 35 is rotatably connected with a rectangular block 36.

[0032] When the staff needs to block the wire connection port of the protector body 1, by pulling the elliptical plate 34, the sliding plate 32 is driven to slide on the inner surface of the sliding frame 31. The sliding plate 32 drives the baffle 33 to move. The rotating screw 35 rotates in the mounting block 38, and the screw 35 drives the rectangular block 36 to move until the rectangular block 36 is inserted into the limiting groove of the sliding frame 31, avoiding the situation that the position of the baffle 33 changes during the movement of the protector body 1. When it is necessary to open the baffle 33, by rotating the screw 35 in the mounting block 38, the screw 35 drives the rectangular block 36 to move until the rectangular block 36 disengages from the limiting groove of the sliding frame 31. The elastic force of the spring 37 drives the sliding plate 32 to slide on the inner surface of the sliding frame 31 and automatically open and maintain a certain position, achieving the effect of protecting the wiring port of the protector body 1. It avoids the situation that when the protector body 1 is not in use, dust or sundries in the external air enter the inner cavity, resulting in poor contact during the connection with the connecting wire, and improves the practicability of the device.
