When hydraulic oil is pumped back into the oil storage tank 1, the level of the hydraulic oil in the oil storage tank 1 rises, the hydraulic oil generates buoyancy to push the floating frame 91 and the upper device thereof to move upwards, the pawl 94 is separated from the ratchet strip plate 72, the compressed fourth compression spring 74 resets to drive the rack plate 71 and the upper device thereof to move away from the liquid return pipe 35, the magnet plate 75 is separated from the separation frame 76, the compressed return spring 53 resets to drive the flow blocking frame 52 and the upper device thereof to move towards the direction close to the six-sided shaft 22, the flow blocking frame 52 blocks the return pipe 32, the lower pressing plate 61 is separated from the pulling plate 64, the compressed third compression spring 65 resets to drive the pulling plate 64 and the upper device thereof to move upwards and reset, the driving toothed ring 113 is separated from the driving gear 112, the driving gear 112 does not rotate any more, the pumping pump 111 does not pump the hydraulic oil back into the oil storage tank 1, the bevel disc 23 is contacted with the piston body 42, and the operations are repeated, the hydraulic oil is repeatedly used, and when the hydraulic oil is not needed, the worker manually closes the servo motor 21 to stop the operation of the equipment.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
