The specific embodiment
Below in conjunction with accompanying drawing, specify the present invention.
See also Fig. 1-4; But the jack of fast lifting of the present invention comprises upper frame 1, footstock, height adjustment assembly and positioning component, and upper frame is arranged on the footstock; Height adjustment assembly and positioning component are fixed on the footstock, and height adjustment assembly and positioning component are arranged on a side of upper frame.
Upper frame 1 comprises a cylinder 12 and is arranged on the arc shape support portion 11 of cylinder one end that one side of cylinder is provided with ratchet row 121.Ratchet row 121 is provided with several downward-sloping teeth 1211.
Height adjustment assembly comprises jacking block 35, jacking block pull back spring 34, contiguous block 33, shifting bar 32 and mobile lever pin 31; Contiguous block 33 is fixed on the shifting bar 32 through moving lever pin 31; Contiguous block 33 comprise one can ccontaining jacking block 35 first groove of first end; First end of jacking block 35 comprise one can ccontaining jacking block pull back spring second groove 351, jacking block 35 is fixed in first groove of contiguous block 33 through jacking block pull back spring 34.Second end 352 of jacking block 35 is the cutter head shape, and the cylinder 12 of its blade and upper frame is relative, and its point of a knife can upwards prop up ratchet row 121 slit.
Positioning component comprises upper frame fixture block 42, release lever pin 41 and trip lever 43, and upper frame fixture block 42 is fixed on the trip lever 43 through release lever pin 41.Upper frame fixture block 42 is the cutter head shape, and the cylinder 12 of its blade and upper frame is relative, and its point of a knife upwards props up ratchet row 121 slit, and its bottom is fixed on the trip lever 43 through release lever pin 41.Positioning component also comprises a safe lock dog 44 and upper frame lock 45, can be provided with in the end of safety lock dog 44 and upper frame lock 45 and can hold the through hole that snap ring 46 passes.
Footstock comprises cover piece 21 and leg 22, and cover piece 21 is arranged on the leg 22.Cover piece 21 hollows are provided with trepanning 211, and an end of upper frame 1 is arranged in the trepanning 211.On cover piece 21, each is provided with and can holds first through hole 212 that shifting bar 32 passes and can hold second through hole 213 that trip lever 43 passes to arrange 121 adjacent two sides with ratchet.On cover piece 21, arrange 121 adjacent two sides with ratchet and also be provided with and can hold the third through-hole 214 that safe lock dog 44 passes, arrange 121 adjacent sides with ratchet and also be provided with and can hold the fourth hole 215 that upper frame lock 45 passes.On cover piece 21, with ratchet arrange 121 relative to a side be provided with to hold and move the fifth hole 216 that lever pin 31 passes and can hold the 6th through hole 217 that release lever pin 41 passes.On cylinder 12, with fourth hole 215 relative sides the 3rd groove 122 that one axis direction along cylinder 12, one end that extend, that can hold upper frame lock 45 inserts is set, the upper frame lock is inserted fourth hole can prevent that upper frame breaks away from footstock.
