Block setting is in support base and stablizes between square, and the upper parallel of the support base is provided with lifting top plate, the lifting
The bottom of top plate is evenly arranged with connection convex block in cross, is equipped with company by pin between the positioning sliding block and connection convex block
Straight panel is connect, the top quadrangle of the support base and the bottom four corners of lifting top plate are mounted on fixed fixture block, solid described in two groups
Determine that stable telescopic rod is vertically installed between fixture block, is uniformly provided with connecting screw hole, the square at the top of the lifting top plate
On be provided with warning reminding device.
Preferably, the bottom of the fixed fixture block offers the L shape card slot matched with support base, the fixed fixture block
Top be provided with and the installation sleeve stablizing telescopic rod and match.
Preferably, between the L shape card slot and support base be transition fit, the installation sleeve and stablize telescopic rod it
Between for interference fit.
Preferably, the bottom of the support base 1 is provided with moving assembly, and the moving assembly includes idler wheel and limit dress
It sets.
Preferably, the quantity at least two of the moving assembly；
Compared with prior art, the utility model has the beneficial effects that the utility model passes through while rotating adjusting nut
Under the action of the rotation and threading force that drive adjusting screw rod, enable positioning sliding block on adjusting screw rod while sliding, thus real
Now to the adjustment of lifting top plate supporting height, the rotation of adjusting screw rod is driven by rotating adjusting nut respectively, makes positioning sliding block
It can be slided on adjusting screw rod respectively, to realize the adjustment to lifting top plate supporting angle, the utility model is being applied to
When the erection of the device of big stroke, does not need the support ground to bottom and be adjusted, can be achieved with to bearing height angle
Adjustment erections can be fixed to the equipment of different model while by uniform connecting screw hole at the top of lifting top plate, it is logical
The mutual cooperation for crossing L shape support plate and fixed jack facilitates and the utility model is fixed on support ground, and it is practical new to improve this
Stability when the support adjustment of type.
