[0019] The present invention will be further described below with reference to the following embodiments, but the scope of the present invention is not limited thereto.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] The pull code of this solution is aimed at the loader brake clamp piston, the structure is as follows Figure 1 As shown, it includes a tubular body 1 and a groove located on the inner wall of the body 1, and the groove is a continuous groove that overlaps end to end.

[0022] like Figure 2-3 As shown, the loader brake caliper piston pull code includes:

[0023] A U-shaped bracket for placement on the piston seat, the U-shaped bracket comprising an upper plate 3 and two side plates 4 located at both ends of the upper plate and extending downward, the upper plate having a through hole;

[0024] A threaded rod, with a base 5 fixedly mounted at the lower end. The base includes two symmetrical first straight sides 6 and a third side 7 and a fourth side 8 connected to the two straight sides. The distance from the first straight side to the axis of the threaded rod is smaller than the distance from the third side and the fourth side to the axis of the threaded rod.

[0025] A circular base 9 (thickness less than the distance from the groove to the bottom of the piston) is fixedly mounted at the lower end of the base;

[0026] Two connecting blocks 10 (thickness less than the height of the groove in the vertical direction) are symmetrically placed on the circular base, and the inner side edge 11 of the connecting block is a second straight edge that abuts the first side edge, and the outer side edge of the connecting block is an arc edge 12, with both ends connected to the second straight edge. When the connecting block is placed on the base, the projection of the arc edge in the vertical direction coincides with the outer edge of the circular base;

[0027] A nut (not shown in the figures) is used to cooperate with the threaded rod and is located above the upper plate when in use.

[0028] Preferably, the base is a centrosymmetrical structure.

[0029] The base is formed by cutting two symmetrical chords from a circular plate.

[0030] The outer diameter of the circular base is the same as or slightly smaller than the inner diameter of the piston.

[0031] The surfaces of the connecting block and the U-shaped bracket are coated.

[0032] The coating is yellow coating.

[0033] During actual use, the circular base sinks to the bottom of the piston, and the U-shaped bracket is placed on the piston seat. Since the U-shaped bracket is stationary, the nut is attached to the upper end surface of the upper plate under the action of gravity of the threaded rod and the various components connected to the threaded rod. When the nut is turned, the threaded rod and the various components on it move upward. When the connecting block is placed on the base and cooperates with the base by fitting the first side and the second side, before moving to the groove, it can only maintain its initial state and move upward with the circular base (the piston is stationary). When it moves to the groove, the rotation of the threaded rod gives the connecting block a thrust, so that the connecting block is partially stuck in the groove, driving the piston to move upward, thereby removing the piston.

[0034] It should be noted that the embodiments described above are only used to explain the present invention and do not constitute any limitation to the present invention. The present invention has been described with reference to typical embodiments, but it should be understood that the words used therein are descriptive and explanatory words, rather than restrictive words. The present invention may be modified as provided within the scope of the claims of the present invention, and the present invention may be revised without departing from the scope and spirit of the present invention. Although the present invention described therein relates to specific methods, materials and embodiments, it does not mean that the present invention is limited to the specific examples disclosed therein. On the contrary, the present invention can be extended to all other methods and applications with the same functions.
