In other embodiments, the elastic base 13 can also be provided with only one movable groove 132, the elastic structure 2 can also be provided with only one elastic piece 22, and the connecting piece 22 can also be positioned and connected with only one second end wall 1311, and the tightness of the connection between the main body 1 and the external brake pad can also be improved through the elastic structure 2.

When the brake is in an energized state, the clutch plate 4 is released from pressing the brake pad 5 under the magnetic field attraction of the magnetic yoke structure 3 and tightly abuts against the magnetic yoke structure 3, at this time, the brake pad 5 can rotate under the driving of the free-aligning coupling 100 and the external vehicle running transmission shaft connected with the free-aligning coupling 100, thereby allowing the vehicle to run; when the brake is in a de-energized state, the clutch plate 4 presses the brake pad 5, the brake pad 5 is clamped between the clutch plate 4 and the fixed plate 6 and cannot rotate, thereby preventing the vehicle from running.
