[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that in the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0014] See also Figure 1-2 The embodiment of the utility model provides a tool for manual release of vehicle parking brake, including an adjusting rod 1, a spring 4 and a sleeve 2. The adjusting rod 1 and the sleeve 2 are connected by a universal joint 3. The end of the sleeve 2 away from the universal joint 3 is provided with an inner hexagonal hole matched with the head of the manual release bolt. The spring 4 is sleeved on the outside of the universal joint 3, and one end of the spring 4 is sleeved on the adjusting rod 1 and fixedly connected to the outer wall of the adjusting rod 1, and the other end is sleeved on the sleeve 2 and fixedly connected to the sleeve 2.
[0015] The two ends of the spring 4 are respectively welded to the outer wall of the adjusting rod 1 and the outer wall of the sleeve 2, and the end of the adjusting rod 1 away from the universal joint 3 is provided with a hexagonal shaft section 11 for cooperating with a socket wrench, and the socket wrench is a socket wrench well known to those skilled in the art. It should be noted that the parts not described in detail in this application are all prior art.
