Problems solved by technology

[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, even with certain security issues

Abstract

The invention discloses an automobile tire maintenance jack, which 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 of the lifting column is fixedly connected with a horizontal head; The vertical lifting column goes up and down; the structure of the invention is simple, and the structure of the hand-operated hydraulic jack with complex structure and high cost is eliminated. When the jack needs to be locked and the clutch is engaged, the rotation direction of the brake shaft and the stop gear When a conflict occurs, the transmission chain of the transmission system of the entire device is locked, so that the anti-rotation gear stops the active rotation of the active outer ring gear; at this time, a stable locking state is realized; the safety performance is high.
