Abstract
The utility model discloses a screw tightener for tires of automotive vehicles, which comprises a rotating rod (1), a sleeve barrel (2), a handle (3) and a casing (4), wherein the other end of the rotating rod (1) is connected with a gear (5) arranged in the casing (4), and positive and negative teeth (6) are arranged on the gear (5); the positive and negative teeth (6) correspondingly and movably contact a positive and a negative shifting forks (7), and the other ends of the positive and the negative shifting forks (7) contact a shifting handle (8). When the screw tightener for tires is used, the positive and the negative shifting forks are arranged in the position that one of the positive and the negative shifting forks contacts the positive and negative teeth, and the other one is disengaged from the positive and the negative by adjusting the shifting handle, so that the counter-clockwise rotation of the gear can be ensured. Inversely, the positive and the negative shifting forks are arranged in a position opposite to the former position by readjusting the shifting handle. The utility model which can be operated to rotate continuously has the advantages of subdued and fluent force and low labor intensity.
Description
Affiliated technical field
The utility model belongs to a kind of motor vehicle repair outfit, is a kind of take-up of automobile tyre screw particularly.
Background technology
At present, when tyre of heavy truck keeps in repair, need instrument that tire screw is unloaded and loads onto.Existing dismantling device is the fixing sleeved bull stick of one one end, is inserted with vertical with it handle on the bull stick.During operation, sleeve is docked with screw, turning handle unloads screw.The deficiency of its existence is: when handle rotates operation discontinuous, firmly inharmonious, effort and inconvenient.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved automobile tyre screw tightener is provided, and it can continued operation, and the loading and unloading screw is convenient, laborsaving saving time.
For reaching above-mentioned purpose, the utility model is taked following technical scheme: the utility model includes: bull stick, sleeve, handle and shell, one end coupling sleeve of bull stick, handle is connected in an end of shell, it is characterized in that: the gear in the other end of bull stick and the shell connects, have positive and negative tooth on the gear, touched positive and negative shift fork mutually with the corresponding activity of positive and negative tooth, positive and negative shift fork end in addition touches mutually with group handle.
The utility model is taked technique scheme, has following beneficial effect: when the utility model uses, sleeve and tire screw are touched, during the dismounting screw, adjust to dial handle and make positive and negative shift fork be in one to touch mutually with positive and negative tooth and another and the position of positive and negative tooth disengaging, the guarantee gear can be rotated counterclockwise; Otherwise, when tightening the screw, adjust group handle and make positive and negative shift fork be in the position opposite with the former, ensure that gear can turn clockwise.The utility model is rotary manipulation continuously, and is firmly smooth and easy gently, reduces labour intensity.
