A ventilation valve of a hydraulic jack is dedicated to be mounted at an outer wall of an oil storage tank of a hydraulic jack. The hydraulic jack includes a valve seat, a valve ball, and a cap. When the jack is not operated, a valve hole is opened; the vent of the cap is communicated with the oil storage tank of the jack so as to maintain the equilibrium of the pressure of the oil storage tank; thereby the piston of the pump can suck oil successfully so that the oil is absorbed into the oil chamber of the pump to be saturated therein. At the moment that the valve ball ejects upwards rapidly, the oil buffer chamber can buffer high pressure draining oil until the oil return operation of the jack is accomplished.

A jack having a detachable rear-end handle comprises a wheeled jack and a hand-held ring. Two sidewalls of the jack are each provided with a pair of blocking pieces respectively mounted on an upper location and a lower location about a screw nut of a rear shaft. The hand-held ring can be coupled to screw nuts of a rear shaft. The blocking pieces further restrict the rotation of the hand-held ring. The connection of the hand-held ring at the rear end of the jack not only facilitates carrying the jack but also controlling the movements of the jack to a proper lift point.

A hydraulic lifting device capable of being rapidly raised in a mechanical movement by use of a linkage mechanism that comprises a lifting device, a rotating shaft and a linkage. The lifting device has a basic construction of two vertical side plates, a lifting arm, and a saddle support plate at the front end of the lifting arm. An outer end of the saddle support plate has an axial rod at a predetermined position. The rotating shaft extends through a clearance hole in the vertical side plate of the lifting device. The rotating shaft is integrally attached to the linkage, and the linkage has two extreme ends which are integrally attached to both the rotating shaft and the axial rod in the saddle support arm. By the above components and mechanical assembly, as the rotating shaft is rotated the linkage is driven through the axial rod in the saddle support plate and the lifting arm is rapidly raised in a mechanical movement, not a hydraulic movement, to the support point of the vehicle to be lifted by a secondary hydraulic action.

A car waxing machine with a driving handle comprises a car waxing machine and two pivotal handles. Each pivotal handle is a rod shape arm. The arm has a bent structure. Thereby, a rear section of the pivotal handle has a pivotal end and a front end thereof has an arm. By the arms of the two pivotal handles to be pivotally connected to two sides at the rear end of the car waxing machine, a structure with two arms at two sides which is rotatable for adjust the orientations of the arm is formed. Thereby, the arms are adjustable to horizontally extend to the two sides of the car waxing machine. Therefore, the user may adjust the arms to match the habits of using a car waxing machine and further forces can be uniformly applied to the machine.

Jack

An auxiliary tool clip of a jack. At a predetermined position of a shroud of the jack is installed with a positioning seat. The elastic clip is secured to the positioning seat and the shroud by a positioning shaft. A surface of the positioning seat is distributed with positioning holes. A bottom of the elastic clip is installed with at least one positioning nose. When the positioning nose rotates, the positioning nose moves along the positioning holes on the surface of the positioning seat. The positioning shaft penetrates through the elastic clip, positioning seat and shroud so as to be movably locked. Thereby, an elastic clip is pivotally installed thereon, so that the clip can be used to clip a flashlight, a tire pressure meter or other auxiliary tool and the orientation of the clip is changeable through rotation.
