By providing the orifice 48 and the orifice 49, when the connecting disc 38 rises, the hydraulic oil 47 can smoothly flow through the orifice 48, and when the connecting disc 38 falls, because the diameter of the orifice 49 is extremely small, the resetting of the connecting disc 38 is slow, so that the line can be automatically recovered after a long time, the user is given time to handle overload, and active disassembly and maintenance are not needed.
Through the setting of screw 45, can adjust the height of lifter plate 35, and then adjust the degree of compression of pressure spring 37 to adjust the precompression between pressure disk 42 and spacing ring 43.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
