The specific embodiment
Referring to Fig. 1, the schematic perspective view that has shown the hand fork lifter of the adjustable plate width that puts one's child in a boarding nursery of the present invention, this hand fork lifter comprises drive spindle 10, hydraulic ram 20, cross bar 30 and two supporting plates 40, wherein drive spindle 10 can be operated so that hydraulic ram 20 rises or reduces, hydraulic ram 20 is connected with cross bar 30, and two supporting plates 40 are separately positioned on the two ends of cross bar 30.
Referring to Fig. 2, the part schematic perspective view that has shown the width adjusting apparatus of supporting plate of the present invention, this width adjusting apparatus 1 comprises the strip shape through hole 31 on the both sides end face that is positioned at cross bar 30 and is positioned at connecting strap 41 on the top of each supporting plate 40, the both sides of every connecting strap 41 are respectively equipped with two screws 42, every connecting strap 41 is fixed by two bolt of rear end plates 43, bolt of rear end plate passes screw 42 and through hole 31, thereby supporting plate is fixed on the cross bar 30.
When the user uses this hand fork lifter, and find that the distance between the supporting plate is improper, the user can unclamp bolt of rear end plate, adjusts the position of supporting plate on each through hole more as required, the distance between the supporting plate being carried out hand adjustment, thereby finishes the adjustment of distance.
Referring to Fig. 3, the part schematic perspective view that has shown the height adjuster of auxiliary wheel of the present invention, auxiliary wheel 45 is arranged at the supporting plate bottom, this height adjuster 2 comprises actuating arm 21, and an end of this actuating arm 21 and hydraulic ram 20 articulate, and the other end then articulates with cross bar 30, the downside of actuating arm 21 shows and extends a projection 211, projection 211 free end is provided with roller 212, and wherein roller 212 is two, on the rotatable free end that is connected in projection 211 of roller shaft.
Referring to Fig. 4, this height adjuster 2 also includes the slide bar 22 that is positioned at supporting plate 4 bottoms, this slide bar 22 can slide in the supporting plate bottom surface, simultaneously, position in the bottom of supporting plate 4 corresponding to roller 212 is provided with slide 23, this slide 23 comprises a top board and two side levers, two side levers form guide rail 231 in the top board both sides and between side lever, in guide rail 231, be provided with the guide block 44 affixed with the supporting plate bottom surface, this slide 23 can slide along guide block 44 and align sliding function to provide, simultaneously, two side levers of slide 23 are fixed on an end of slide bar 22.
