Abstract

The invention discloses an automobile tire maintenance jack. The automobile tire maintenance jack comprises a base. A vertical fixing column is fixedly connected to the base, and a vertical lifting column is movably arranged in the vertical fixing column. The top end of the lifting column is fixedly connected with a horizontal ejector head. The ejector head is lifted up and down along with the vertical lifting column. The automobile tire maintenance jack is simple in structure, and gets rid of a hand-cranking hydraulic jack structure which is complex in structure and high in cost, when the jack needs to be locked to enable a clutch to be in an engaged state, the rotation direction of a brake shaft conflicts with the rotation direction of a rotation stopping gear, and a transmission chain of a transmission system of the whole device is locked. Therefore, the rotation stopping gear stops driving rotation of a driving outer gear ring. At the moment, the stable locking state is realized. The safety performance is high.

Description

technical field [0001] The invention belongs to the field of automobile jacks. Background technique [0002] Most of the existing hand jacks adopt hydraulic structure, which has the problems of oil leakage, complex structure, high cost and inconvenient maintenance; and the existing hand jack needs only a small The hand-cranked part can be rotated by the external force. Passing pedestrians or children may touch the hand-cranked part when they are playing. Especially when the maintenance personnel are repairing the bottom of the car, the hand-cranked part rotates under the action of external force, which will make the lifted car body unsteady. stable, and even have certain security issues. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides an automobile tire maintenance jack with high safety. [0004] Technical solution: In order to achieve the above object, the automobile tire...
