[0006] The above-mentioned protective device of the present application has a movable side slide plate. When the length needs to be extended, the side slide plate can be unfolded outward and locked and fixed by a locking mechanism. In this way, when the protective devices are connected, there will be no problem of insufficient length and resulting gaps. It can also solve the problem of poor flexibility and adaptability of the protective devices in the related technology.

[0007] In some embodiments, the protective body is a triangular stable structure, which is mainly configured to be a triangle for its stability.

[0010] In some embodiments, a ball or roller component is provided in the lower slide groove to assist the sliding of the side slide plate. The purpose of providing the ball or roller component is to reduce friction and facilitate the movement of the side slide plate.

[0011] In some embodiments, the protective device also includes a driving structure for driving the side slide to move, the driving structure includes a gear arranged in a lower sliding groove that is rotated by a rotating shaft, and the upper end of the side slide is provided with a rack that matches the gear. The gear drives the rack during the rotation process to make the side slide move in the length direction of the protective body, and the end of the rotating shaft is connected to a hand crank or a driving motor for driving it to rotate.

[0012] The gear can drive the rack and the side slide plate to move during the rotation process, and the gear can be driven by a hand crank or an electric drive motor.

[0014] In some embodiments, the protective device further comprises a screw, and the base is further provided with a downwardly penetrating insertion hole, and the screw can be vertically inserted into the insertion hole and fixed to the ground component. The screw is mainly used to ensure that the protective device does not shift, and specifically, a threaded tube can be driven into a preset ground position, so that the screw can be threadedly fastened with the threaded tube.

[0015] In some embodiments, the base is further provided with a cylinder for placing the screw, and a magnetic attraction member for adsorbing the screw is further provided in the cylinder. The purpose of providing the circular tube is to place the screw in it when the screw is not in use, and the magnetic attraction member is used to prevent the screw from falling off, and the specific magnetic attraction member can be a strong magnet, or a magnetic layer doped in the circular tube.

[0016] In some embodiments, a roller is further provided at the bottom of the base, so as to facilitate the displacement of the protective device.
