When the front poking arm 42 rotates clockwise to be close to the brake separating handle 2, the front poking arm 42 is pulled forwards to enable the front poking arm 42 to rotate forwards along the limit knob seat 41, at the moment, the first torsion spring connecting shaft 411 starts to accumulate elastic potential energy, when the front poking arm 42 rotates to be supported by the limit cam 412, the front poking arm 42 continues to rotate clockwise, whether the front poking arm 42 can pass through the brake separating handle 2 or not is observed, if the front poking arm cannot pass through the brake separating handle 2, the rotation angle of the limit cam 412 is adjusted, the bulge supporting the front poking arm 42 is switched until the front poking arm 42 can pass through the brake separating handle 2 clockwise when in a front poking state, and after the front poking arm 42 passes through the brake separating handle 2, the front poking arm 42 is loosened to enable the first torsion spring connecting shaft 411 to release the elastic potential energy to drive the front poking arm 42 to rotate backwards to be parallel to the front end face of the insulating installation shell 1.

Because the brake release handle 2 is in an inclined state in the brake release state, when the bidirectional inclined pressing plate 43 is in a horizontal state, the bidirectional inclined pressing plate can be attached to the upper surface of the brake release handle 2 under the action of the second torsion spring connecting shaft 422, so that the contact area with the brake release handle 2 is increased.
If the force of the bi-directional inclined pressing plate 43 to press the brake release handle 2 is insufficient or large, the screw on the fixed rotary ring 34 is loosened, the fixed rotary ring 34 is rotated according to the direction of the required increase or decrease of the torsion force, and then the screw is switched to be screwed into the corresponding through hole, so that the bi-directional inclined pressing plate 43 can maintain proper pressure on the brake release handle 2.
