It is connected between structure 3 by several connecting shafts 6,3 bottom end of scissor link mechanism is hinged in the fixed plate 7 of 1 side of pedestal, cuts
The fork 3 bottom other end of link mechanism is slidably located in the fixed plate 7 of 1 side of pedestal, and 3 top one end of scissor link mechanism is hinged
On the plane cam 4 for being located at 1 side of pedestal, the 3 top other end of scissor link mechanism is slidably provided at 1 side of pedestal
On plane cam 4, plane cam 4 includes a upwardly recessed groove 1, and the inner wall of groove 1 is equipped with sliding surface, plane cam
4 further include a horizontal support surface 10 for being lower than sliding surface, and plane cam 4 is with the horizontal movement and idler wheel 2 of idler wheel 2 in sliding surface
It is supported and goes up and down by idler wheel 2 with the sliding in horizontal support surface 10.
In order to which the idler wheel 2 slided to horizontal direction limits, be equipped in the fixed plate 7 of 1 two sides of pedestal respectively with it is flat
The adaptable groove 29 of face cam 4.
In order to realize the supporting role of scissor link mechanism 3 in the vertical direction to plane cam 4,1 two sides of pedestal are consolidated
The sliding slot 1 for the 3 bottom other end of scissor link mechanism and the sliding of the top other end is equipped on fixed board 7, on plane cam 4
Equipped with the sliding slot 2 12 for the 3 bottom other end of scissor link mechanism and the sliding of the top other end.
In order to which the rolling for keeping idler wheel 2 smooth is divided into horizontal support surface 10, sliding surface includes a vertical plane and an inclined-plane, inclined-plane
Junction between horizontal support surface 10 forms smooth transition slope.
In order to, in lowest order, idler wheel 2 is fixed in plane cam 4, the connection of vertical plane and inclined-plane in plane cam 4
Place forms smooth transition arc surface.
In order to drive the roll-sliding in level of idler wheel 2, horizontal drive mechanism includes the ball screw driven by motor 17
13, feed screw nut 14, nut seat 15 and a pair of idler wheel 2 for being movably fixed to 15 two sides of nut seat respectively, are movably fixed to rolling

The utility model utilizes the advantage of plane cam structure Yu scissor structure simultaneously, in conjunction with conservation of energy superposition principle,
Physical burden, while compact-sized microminiaturization are effectively increased, can effectively overcome the problems, such as various narrow spaces but load weight, together
When have the high advantage of jacking positioning accuracy.According to " conservation of energy superposition principle " principle, be converted to vertically using horizontal movement
Movement, i.e., kinetic energy is converted to gravitional force, according to function=power × work distance principle, by increasing distance so that power is effectively reduced
Demand, so that bigger load can be jacked it is only necessary to 17 torsion of motor of very little.
Above are merely preferred embodiments of the utility model, it is not intended to limit the utility model, it is noted that for
For those skilled in the art, without deviating from the technical principle of the utility model, if can also make
Dry improvement and modification, such improvement and modification also should be regarded as the protection scope of the utility model.
