One step is preferred, as shown in figure 5, the relatively described side of threaded portion 412 of the adjusting screw rod 41 is provided with thrust bearing 43, it is described to push away
Power bearing is rounded, transmitting thrust when having the function that to keep out, when the thrust bearing 43 rotates with the adjusting screw rod 41 with
The bearing pin of homonymy is abutted, and the rotation section of the first connecting rod mechanism 11 and second connecting rod mechanism 12 is bestowed to grip force, that is, is pushed away
First connecting rod mechanism 11 and second connecting rod mechanism 12 are extruded when power bearing 43 is with the adjusting screw rod 41 drive, makes upload
Lever component and the increase of the rotational angle of underdrive bar assembly, so as to drive support base to raise, and thrust bearing 43 is with described
Adjusting screw rod 41 drives lower unclamp to push the bearing pin of homonymy, make first connecting rod mechanism 11 and second connecting rod mechanism 12 in gravity or
The lower automatic opening of external force effect, moves support base and declines.Easy to use, transmission coordinates reliable.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
