[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, the present invention provides a novel safety bead structure, including a safety bead body 1 and a carbon brush 2. The top of the carbon brush 2 is provided with an installation groove 3, and the safety bead is located inside the installation groove 3. The safety bead body 1 is made of insulating plastic, and a spring 4 is fixedly connected to the top of the safety bead body 1.
