Between connected by the second elevating mechanism 8, the horizontal length of the workbench 6 is less than the length of the Auxiliary support platform 4；
The collateral support body 10 being vertically arranged, the collateral support body 10 are equipped at least two, and along the vertical of the workbench 6
Axisymmetrical is arranged；
At least two horizontally disposed limiting plates 12, the limiting plate 12 are connected on two collateral support bodies 10,
And it is done relative motion and counter motion by control device driving.
As a further improvement on the present invention, the control device includes：
The the first auxiliary adjustment plate 14 that is slidably connected on the collateral support body 10, and can move horizontally, described first
There are two the settings of auxiliary adjustment plate 14, and is respectively positioned on immediately below the limiting plate 12,14 upper surface of the first auxiliary adjustment plate
It is provided with the first tooth；
Positioned at the surface of the first auxiliary adjustment plate 14, and with the first adjustment gear 16 of first tooth engagement,
First adjustment gear 16 and the second tooth engagement in 12 lower surface of the limiting plate is set.
As a further improvement on the present invention, further include：
Intermeshing second adjustment gear 18 and third adjustment gear 20,12 upper surface of the limiting plate are provided with third
Tooth, second adjustment gear 18 and the third tooth engagement；
The the second auxiliary adjustment plate 22 that is slidably connected on the collateral support body 10, and can move horizontally, it is described
There are two the settings of second auxiliary adjustment plate 22, and is respectively positioned on right over the limiting plate 12, under the second auxiliary adjustment plate 22
Surface is equipped with third tooth, and the third tooth with the third adjustment gear 20 for engaging.
As a further improvement on the present invention,

Between be both provided with the first inclined-plane；
The Auxiliary support platform 4 and the both ends of the surface of the workbench 6 are equipped with and first inclined-plane with its top surface
The second equal inclined-plane of slope.
As a further improvement on the present invention, the limiting plate 12, the first auxiliary adjustment plate 14 and the second auxiliary adjustment
Plate 22 includes the horizontal fixed plate 24 being fixed on the collateral support body 10, and is slidably connected at described horizontal fixed
Horizontal sliding panel 26 on plate 24.
As a further improvement on the present invention, first elevating mechanism 2 and second elevating mechanism 8 be oil cylinder or
Cylinder.
The concrete principle of the present invention is as follows：
(1) first elevating mechanism 2 is oil cylinder, and oil cylinder rises, and workbench 6 is driven to be promoted；
Initial spacing between (2) first auxiliary adjustment plates 14 is more than the horizontal size of workbench 6, but less than auxiliary branch
Support platform 4 horizontal size, therefore, workbench 6 can pass through the spacing, but Auxiliary support platform 4 can not by the spacing,
When Auxiliary support platform 4 and the first auxiliary adjustment plate 14 contact, active force makes the first auxiliary adjustment plate 14 do counter motion,
Auxiliary support platform 4 is set to pass through the first auxiliary adjustment plate 14；
When (3) first auxiliary adjustment plates 14 do counter motion, the first adjustment gear 16 is pushed to do clockwise movement, first adjusts
The movement of section gear 16 drives limiting plate 12 to do relative motion；
(4) although limiting plate 12 does relative motion under the action of the first adjustment gear 16, its spacing is tapering into,
At this point, workbench 6 is still able to across the spacing to its top stroke；
(5) second elevating mechanisms 8 are cylinder, and after workbench 6 moves to its top stroke, cylinder drives workbench
6 declines make it be placed on the upper surface of limiting plate 12, and the position of workbench 6 is its normal place at this time；
(6) after processing is completed, cylinder moves upwards, and workbench 6 is contacted with the second auxiliary adjustment plate 22, and pushes two
Second auxiliary adjustment plate 22 does counter motion, is equipped with the second adjustment gear between the second auxiliary adjustment plate 22 and limiting plate 12 at this time
18 and third adjustment gear 20, when the second auxiliary adjustment plate 22 does counter motion, limiting plate 12 also does counter motion simultaneously, limit
Spacing between plate 12 meets workbench 6 and passes through；
(7) oil cylinder moves downward, and the spacing between the first auxiliary adjustment plate 14 is passed through, to drive workbench 6 to drop to
Home position.
The above example only one such embodiment of the present invention, the description thereof is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
