[0027] In this embodiment, the brake shaft 101 is mainly used to drive the friction plate 102 to rotate.

[0028] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The left surface of the sealing end plate 103 is respectively fixedly mounted with a rotating column 104 and a brake hydraulic cylinder 105, and the outer side of the rotating column 104 is respectively movably sleeved with a first brake arm 1041 and a second brake arm 1042, and a tension spring 1043 and a brake shoe 1044 are respectively arranged between the first brake arm 1041 and the second brake arm 1042;

[0029] Specifically, the No. 1 brake arm 1041 and the No. 2 brake arm 1042 are symmetrically distributed front and back about the rotating column 104, the right end of the brake hydraulic cylinder 105 penetrates the left side surface of the sealing end plate 103 and extends to the right side thereof, and its telescopic end is respectively in contact with the ends of the No. 1 brake arm 1041 and the No. 2 brake arm 1042, the tension spring 1043 is connected with the No. 1 brake arm 1041 and the No. 2 brake arm 1042 through the pulling hole, the brake shoe 1044 is respectively installed on the right side surface of the No. 1 brake arm 1041 and the No. 2 brake arm 1042, the brake shoe 1044 is located inside the housing 1, and its facing side surface is in contact with the outer side surface of the friction plate 102;

[0030] In the present embodiment, the setting of the rotating column 104 is mainly to facilitate the rotational coordination between the No. 1 brake arm 1041 and the No. 2 brake arm 1042, and the setting of the tension spring 1043 is mainly used to drive the No. 1 brake arm 1041 and the No. 2 brake arm 1042 to rotate toward each other, so that the brake pad 1044 is in contact with the friction plate 102, thereby realizing the combination of the brake pad 1044 and the friction plate 102; the setting of the brake hydraulic cylinder 105 is mainly used to drive the No. 1 brake arm 1041 and the No. 2 brake arm 1042 to rotate away from each other, so that the brake pad 1044 is separated from the friction plate 102, thereby realizing the complete separation of the brake pad 1044 and the friction plate 102, thereby meeting the braking needs of the user.
