Embodiment Construction

[0010] In Fig. 1, on the straight rod (4), the pistons (6) are successively mounted and docked with the fixed layer (5), forming multi-layer direct pressure cylinders (3) and then installed in the outer case (2). The straight rod (4) is connected with the force point (14), the lever (1) is connected with the fulcrum (13), hydraulic oil is installed in the outer box (2), and the lever (1) is pushed by hand so that each cylinder cavity is filled with liquid. Oil pipe (9) is connected with telescoping rod (10), and the pressure of spring (11) will guarantee the pressure that resets. Outer box (2) should be filled with oil.

Abstract

A multi-layer straight compressing cylinder with longer action distance of lever is composed of lever, straight rod connected with lever, fixed layer and piston. A telescopic rod unit with restoring spring is connected via an oil tube to said cylinder for operating the telescopic rod effectively.

Description

Technical field [0001] The invention relates to a hand hydraulic device, especially a hydraulic cylinder capable of extending a short distance to a long distance without reducing force response. Background technique [0002] At present, the known hand-pressed hydraulic device structure is formed by a hand-pressed hydraulic cylinder, an oil pipe, and a telescopic rod. Hand hydraulic cylinders are usually several times smaller than telescopic rods. When the liquid is pressed once to the telescopic rod, the stroke that the telescopic rod stretches out is very short, so it can not be used for expansion, but can only be used for amplifying force (jack). To obtain the elongation, it is necessary to press the hydraulic cylinder several times by hand to obtain it. On the contrary, if the handle pressure cylinder is set larger than the telescopic rod to obtain a long distance, it will reduce the force and the reaction force will become smaller, so if there is length, there will be n...
