Fig. 1 is the structure diagram of the expansion fixing device of the present invention；
Fig. 2 is the schematic diagram of the expansion fixing device of the present invention in embodiment.
The mark of each component is as follows in attached drawing：1st, expander, 2, expansion piece, 3, bottom plate, 4, top plate, 5, connecting seat, 6, spiral shell
Line blind hole, 7, connecting rod, 8, cylinder.
Specific embodiment
The technical solution in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only the part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
All other embodiment that technical staff is obtained without making creative work belongs to the model that the present invention protects
It encloses.
Referring to Fig. 1, the embodiment of the present invention includes：A kind of expansion fixing device, including expander 1, the expander 1
Including top plate 4 and bottom plate 3, multiple expansion pieces 2 are provided between the top plate 4 and bottom plate 3, the expansion piece 2 is can be with arc
The laminated structure of bending, the both ends of the expansion piece 2 can outwards heave at the middle part of the expansion piece 2 after being under pressure.
Connecting seat 5 is provided on the top plate 4 of the expander 1, tapped blind hole 6, the spiral shell are provided on the connecting seat 5
Line blind hole 6 and the expander 1 are coaxial.
As shown in Fig. 2, expander 1 is placed in cylinder 8, the lower end of connecting rod 7 is stretched into the tapped blind hole 6 of connecting seat 5, even
It is provided with external screw thread on the lower end of extension bar 7, the external screw thread on the lower end of connecting rod 7 matches with the internal thread in tapped blind hole 6, even
Extension bar 7 is connected with expander 1.When expander 1 is not under pressure, connecting rod 7 can drive expander 1 in cylinder 8
In slide up and down, adjust connecting rod 7 height.When being pressed by connecting rod 7 to expander 1, the middle part of expansion piece 2 can be outside
It heaves, props up the inner wall of cylinder 8, expander 1 cannot slide up and down in cylinder 8, and position is fixed.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright description is made directly or indirectly is used in other relevant technology necks
Domain is included within the scope of the present invention.
