Scissor-type lifting mechanism is left and right to be arranged symmetrically；The interior equidistantly distributed of fork arm 21, interior fork arm 21-1 equidistantly distributeds,
The outer equidistantly distributed of fork arm 22, outer fork arm 22-1 equidistantly distributeds.
The bottom of operation platform 3 is left and right to be arranged with fixed chute plate 31-1, upper fixed chute plate 31, the top of base 1
Portion is left and right to be arranged with lower fixed chute plate 11-1, lower fixed chute plate 11, scissor-type lifting mechanism 2 both with upper fixed chute
In being slidably matched, scissor-type lifting mechanism 2 is again sliding with lower fixed chute plate 11-1, lower fixation for plate 31-1, upper fixed chute plate 31
Frid 11 is in be slidably matched.
It is visible in figure, upper fixed chute plate 31-1, upper fixed chute plate 31, lower fixed chute plate 11-1, lower fixed chute
Plate 11 is equipped with long slot bore (not indicating), scissor-type lifting mechanism 2 be located at the outer fork arm 22-1 of bottom, outer fork arm 22 (such as
By arranging roller) it can be slided respectively in lower fixed chute plate 11-1 long slot bore, the long slot bore of lower fixed chute plate 11
It is dynamic, meanwhile, scissor-type lifting mechanism 2 is located at the interior fork arm 21-1 at top, interior fork arm 21 (such as by arranging roller) respectively can
Long slot bore in upper fixed chute plate 31-1, on fixed chute plate 31 long slot bore in enter line slip.
Transmission mechanism include a rotary shaft 4, be fixedly arranged on respectively on its shaft end (being shown in right-hand member) of rotary shaft 4 one it is hand
Handle 40 and a ratchet 41, wherein, rotary shaft 4 is supported by a pair of interior fork arms 21 being arranged symmetrically, interior fork arm 21-1, in interior fork arm
A detent pin 5 is provided with 21, adjacent to the position of ratchet 41 and can be nibbled loaded on the ratchet 51 in the detent pin 5, ratchet 51 with ratchet 41
