In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0018] Please see attached Figure 1-2 , a labor-saving tool for installing and debugging a handbrake, comprising a connecting pipe, a limit block, a groove, a fixing device and a handle, the connecting pipe is hollow, the connecting pipe is a PVC pipe, the length of the connecting pipe is between 10-15cm, the connecting pipe and the handle are connected by a fixing device, the limit block is arranged on the side of the connecting pipe close to the fixing device, the groove is arranged on the side of the limit block away from the handle, and the overall length of the connecting pipe, the fixing device and the handle is 25-30cm;

[0019] The fixing device comprises a connecting plate, a threaded hole and a bolt. The threaded hole is arranged on the connecting plate. The length of the connecting plate is 5-10cm. There are two threaded holes. The bolts pass through the threaded holes and are connected with the connecting pipe and the handle respectively.

[0020] By adopting the above technical solution, when in use, the connecting pipe and the handle are assembled. After the assembly is completed, it should be noted that the connecting pipe, the fixing device and the handle are in a stepped shape as a whole. Since the connecting pipe is hollow, when in use, the hollow end of the connecting pipe is put on the handbrake, and then the connecting pipe and the handbrake are driven by the handle to pull the handbrake to adjust the tightness of the handbrake. By setting the connecting pipe and the handle to pull the handbrake, the length of the handbrake is extended, which plays the role of a labor-saving lever and reduces the force of pulling the handbrake, so that the handbrake can be loosened without much effort, which greatly reduces the work pressure of employees;

[0021] Since the space between the end of the handbrake and the vehicle body is limited, although the overall length of the labor-saving tool is longer, it can save more effort, but it is easily restricted by the vehicle body. Therefore, by setting it on the connecting plate and making the length of the connecting plate 8cm, the handle and the handbrake are staggered, and the handle is not on the extension line of the handbrake, thereby increasing the space between the handbrake and the vehicle body, which is convenient for the staff to pull and also convenient for the staff to remove the connecting pipe from the handle without restriction;

[0022] By arranging a limit block in the connecting tube and providing a groove on the limit block, since the end of the handbrake is generally convex, the connecting tube is put on the handbrake so that the end of the handbrake is pressed into the groove of the limit block for limit, thereby preventing the handbrake from slipping inside the connecting tube when pulling.

[0023] In some embodiments, the handle is wrapped with anti-slip tape.

[0024] By adopting the above technical solution and providing the anti-slip tape, the handbrake is not easy to slip when being pulled by the handle, thereby improving the work efficiency of the staff.

[0025] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
