The hydraulic jack means 10 includes a pumping member 20 for pumping hydraulic pressure, and a handle 30 which penetrates the pumping member 20 to operate the pumping member 20.

As is well known, the hydraulic jack means 10 rotates the handle 30 in a clockwise direction to operate a valve (not shown) for adjusting the hydraulic pressure, and then, when the handle 30 is undulated, the pumping member 20 receives the hydraulic pressure. By pumping, the elevating member 40 is raised to lift a heavy object such as a car.

The hydraulic jack means 10 is to lower the elevating member 40 when the hydraulic pressure is recovered by rotating the handle 30 in the counterclockwise direction to lower the raised elevating member 40.

1 and 2, the first ring member 110 is fitted to the cylindrical neck 21 of the pumping member 20, the handle 30 is fitted to the neck 21 by the pumping member Combined with 20.

As shown in FIG. 3, the first ring member 110 forms a groove 111 in which the locking means 130 can be installed on the top surface.

The first ring member 110 is formed at one or more threaded holes 112 on the outer circumference, and is fixed to the neck 21 of the pumping member 20 by screwing bolts to the threaded holes 112, Alternatively, it can be fixed using various coupling methods using pins, keys, and the like.

The shape of the first ring member 110 may be formed in various forms such as a circle and a quadrangle, but may be made in a circle for processing, aesthetics, and safety.

The second ring member 120 is fitted to the handle 30 and is positioned above the first ring member 110 and rotates together when the handle 30 rotates.

For example, the second ring member 120 is formed with one or more threaded holes 122 on the outer periphery, and is fixed to the handle 30 by screwing the bolts to the threaded hole 122, otherwise pins, keys It can be fixed to the handle 30 using a variety of coupling methods, such as.

As shown in FIG. 4, the second ring member 120 protrudes from the outer periphery of the locking jaw 121 that is caught by the locking means 130.

The shape of the second ring member 120 may be formed in various forms such as a circle and a square, but it is preferable that the second ring member 120 is formed in a circle for processing, aesthetics, and safety.
