As further improvement of the utility model, perforation in described first, the tooth form in second on perforation and outer toothed portion
It is involute profile.
As further improvement of the utility model, the end of the adjusting screw rod is provided with movable chuck, the regulation spiral shell
Bar is flexibly connected by the movable chuck with pressing plate.
As further improvement of the utility model, the surface of the pressing plate is mesh contact face, more firmly to press from both sides
Tight object.
The beneficial effects of the utility model are：
1st, the opening angle of grip orifice is easily adjusted, it is convenient to be applied to various occasions；
2nd, friction can be increased by mesh contact face, more firmly grip objects；
3rd, the utility model can be respectively provided with adjusting screw rod and pressing plate on two sides, be easy to some occasion both sides to operate simultaneously.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model

Fig. 2 is exploded perspective view of the present utility model；
Fig. 3 is longitudinal sectional drawing when the utility model opening is angled.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment obtained, belongs to the scope of the utility model protection.
Refering to Fig. 1 to Fig. 3, device, including upper plate 1, lower plate 2 and tune are stretched in a kind of spiral compression top that the utility model is provided
Nodal axisn 3, the top of the upper plate 1 is provided with screwed hole, and for installing adjusting screw rod 4, the bottom of upper plate 1 is provided with first connecting portion
11, first connecting portion 11 is interior to be provided with perforation 12 in first；Perforation 12 is used to install adjustment axis 3 in first.
The bottom of the lower plate 2 is provided with screwed hole, for installing adjusting screw rod 4.The top of lower plate 2 is provided with second connecting portion
21, be provided with second connecting portion 21 with first in perforation 22 in the identical second of perforation 12.Perforation 22 is used to install and adjusted in second
Nodal axisn 3.
Adjusting screw rod 4 is provided with upper plate 1 and the screwed hole of lower plate 2, threaded portion 41 and the screwed hole of adjusting screw rod 4 are matched somebody with somebody
Close, by twisting the hexagonal (hexagon)nut at the top of adjusting screw rod 4, adjusting screw rod 4 can be allowed to move up and down.The end connection of adjusting screw rod 4
There is pressing plate 5.The end of the adjusting screw rod 4 is provided with movable chuck 42, and adjusting screw rod 4 passes through movable chuck 42 and the activity of pressing plate 5
Connection.Specifically, set fluted on pressing plate 5, movable chuck 42 is installed in the groove of pressing plate 5.
For increasing friction force, the surface of pressing plate 5 is mesh contact face 51.
One end of adjustment axis 3 is provided with perforation in the outer toothed portion 31 corresponding with perforation in first 12, outer toothed portion 31 and first
12nd, the fit of perforation 22 connection in second.Tooth form in first in perforation 12, second on perforation 22 and outer toothed portion can be involute
Tooth form, or trapezoidal, triangle tooth form.
When use, spiral compression top of the present utility model is selected to stretch the angular aperture of device according to clamped object
Degree, when needing to change angle, adjustment axis 3 is extracted out, then rotates upper plate 1 and lower plate 2 is arrived after required angle, insert again
