At least one handle 220 is provided on the nut 210, the handle 220 is connected with the rotating member 200 to form a rotating working system, an operator holds the handle 220 and applies force to the handle 220 by hand, and the handle 220 is transmitted to the rotating member 200 to generate rotating motion. Thus, the operator holds the handle 220 to facilitate the rotation and force application. In some embodiments, the number of handles 220 may be two, facilitating even application of force by the operator's hands.

In the dismounting tool special for yaw brake caliper in this embodiment, the rotating member 200 includes a nut 210 for connecting with the screw rod 100, the rotating member 200 can move up and down through the screw rod 100 of the nut 210, the position of the rotating member 200 on the screw rod 100 is adjusted, and at least one handle 220 is arranged on the nut 210 to facilitate the rotation and force application of an operator.

In other embodiments, as shown in fig. 5, the handle 220 is provided with anti-slip patterns for the yaw brake caliper special-purpose dismounting tool.

In particular, when setting up the anti-skidding line on the handle 220, the anti-skidding line includes bellying and depressed part, and the anti-skidding line can turn into the contact of hand and anti-skidding line's surface contact with the hand with the contact of handle 220 on the one hand, and on the other hand, the unsmooth design of anti-skidding line can help operating personnel to arrange the sweat of palm of the hand, because sweat is by the drainage, makes the line formation cavity pressure of anti-skidding line diminish, and outside atmospheric pressure can compress tightly the contact surface and increase frictional force, prevents that the operating personnel from skidding when the application of force is rotatory.

In some embodiments, in order to prevent the yaw brake caliper from being detached, hydraulic oil may pollute the handle, so that an operator applies force to fail, and the concave portions of the anti-skid patterns can help to drain hydraulic oil and increase friction force.

The anti-skid threads can be formed by one or more continuous spiral lines, are curves, are spiral in shape, keep the same distance from the central axis at each point on the spiral lines, rotate at the same angle, form an included angle with the central axis, adjust the included angle, and can provide different friction coefficients to achieve different anti-skid effects.

The shape of the anti-skid patterns can be designed according to different use scenes, and the anti-skid patterns are not limited in the application.

Special assembly and disassembly tools of driftage brake caliper in this embodiment sets up the anti-skidding line on the handle 220, through the arch and the sunken of anti-skidding line, increases handle 220 frictional force, increases operating personnel's grip, and the operating personnel application of force of being convenient for makes rotating member 200 rotatory.

Thus far, the technical solutions of the present application have been described with reference to the embodiments shown in the drawings, however, it will be readily understood by those skilled in the art that the scope of protection of the present application is not limited to these specific embodiments, and the above examples are only for illustrating the technical solutions of the present application, not limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the essence of the corresponding technical solutions in the scope of the technical solutions in the embodiments of the present application.
