[0026] The present utility model will be further described below in conjunction with the accompanying drawings.

[0027] As shown in Figures 1 to 6 A sleeve for adjusting a vacuum pressure regulating valve according to the present utility model includes an outer sleeve 1 and an inner sleeve rod 2. One end of the inner sleeve rod 2 extends into the inner through hole of the outer sleeve 1, and the inner sleeve rod 2 can perform telescopic movement and rotational movement in the inner through hole of the outer sleeve 1. A clamping hole for clamping and rotating an adjusting knob 5 is provided at one end of the inner sleeve rod 2. A clamping member for clamping a nut 4 is provided on the front end face 1-1 of the outer sleeve 1.

[0028] As a preferred embodiment of the present utility model, the clamping member is composed of two bosses 1-2, and the two bosses 1-2 are symmetrically arranged on the front end face 1-1 of the outer sleeve 1. Clamping surfaces 1-2a are provided on both the bosses 1-2, and the two clamping surfaces 1-2a are arranged face to face and parallel to each other. In order to enable the two clamping surfaces 1-2a to clamp the two side end faces of the nut 4, the distance between the two clamping surfaces 1-2a is not less than the side end face distance D. When the present utility model is in use, it is an optimal choice that the clamping surface 1-2a and the side end face are in clearance fit, so that the two clamping surfaces 1-2a can quickly clamp the nut 4.

[0029] As a preferred embodiment of the present utility model, a cylinder cover 3 is connected to the other end of the inner sleeve rod 2. The outer diameter of the cylinder cover 3 is larger than the diameter of the end of the inner sleeve rod 2, mainly for the convenience of the user to rotate the inner sleeve rod 2 and pull the inner sleeve rod 2 back and forth.

[0030] As a preferred embodiment of the present utility model, the inner through hole is a stepped hole, which is composed of a first outer sleeve inner hole 1-3 and a second outer sleeve inner hole 1-4, and the diameter of the first outer sleeve inner hole 1-3 is larger than the diameter of the second outer sleeve inner hole 1-4.

[0031] The inner sleeve rod 2 is provided with a second inner sleeve rod 2-2 matching the first outer sleeve inner hole 1-3 and a first inner sleeve rod 2-1 matching the second outer sleeve inner hole 1-4. The diameter of the first inner sleeve rod 2-1 is smaller than the diameter of the second inner sleeve rod 2-2. One end of the first inner sleeve rod 2-1 is connected to the cylinder cover 3, and the other end of the first inner sleeve rod 2-1 is connected to one end of the second inner sleeve rod 2-2. By setting the inner through hole as a stepped hole and using the corresponding first inner sleeve rod 2-1 and second inner sleeve rod 2-2, it is possible to prevent the inner sleeve rod 2 from being completely pulled out of the inner through hole, playing a limiting role.

[0032] As a preferred embodiment of the present utility model, the clamping hole is provided at the other end of the second inner sleeve rod 2-2. The clamping hole sequentially includes a first inner sleeve rod hole 2-2a and a second inner sleeve rod hole 2-2b from outside to inside. The second inner sleeve rod hole 2-2b is a process hole for processing, and its function has no essential difference from the prior art, so it will not be introduced here. In order to facilitate the first inner sleeve rod hole 2-2a to tightly clamp the adjusting knob 5, the first inner sleeve rod hole 2-2a is a conical hole. The outer diameter of the first inner sleeve rod hole 2-2a is larger than the inner diameter of the first inner sleeve rod hole 2-2a, and the diameter of the second inner sleeve rod hole 2-2b is smaller than the inner diameter of the first inner sleeve rod hole 2-2a.

[0033] The working principle of the present utility model is as follows: The nut 4 is clamped by the two clamping surfaces 1-2a. Then, the first inner sleeve rod hole 2-2a of the inner sleeve rod 2 is sleeved on the adjusting knob 5, that is, the first inner sleeve rod hole 2-2a clamps the adjusting knob 5. Finally, the cylinder cover 3 is rotated to realize the valve adjustment of the vacuum pressure regulating valve. When using the present utility model, it can also be inserted into a narrow space to be connected to the adjusting knob and realize the valve adjustment of the vacuum pressure regulating valve, which greatly facilitates the operation of the user.

[0034] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present utility model are included in the scope of the patent application of the present utility model.
