On be provided with semicircle fixing hole, the quantity of this semicircle fixing hole be two and more than, on the bottom disc of semicircle fixing hole arrange
Having circular shrinkage hole, be provided with female thread inside circular shrinkage hole, the sidewall of disk body is provided with screw, this screw is from the sidewall of disk body
It is through in semicircle fixing hole, screw and semicircle fixing hole degree in a vertical angle, the disk body 1 below screw is provided with screw A, dish
The internal gear ring that is provided with, the cylindrical of gear ring is provided with imploded arcs, and the height of imploded arcs is less than the height of gear ring, the bottom of imploded arcs
By bolt, hollow pin is installed higher than in the bottom of gear ring, semicircle fixing hole, jackscrew is installed, the outer spiral shell of bolt in screw
The female thread of stricture of vagina and circular shrinkage hole screws identical, and the inner cone of jackscrew compresses the nuts in screw downwards, by bolt and
Hollow pin is fixed in semicircle fixing hole by jackscrew, and the imploded arcs of gear ring cylindrical reaches the purpose of fixed gear ring.
The beneficial effects of the utility model are, the external screw thread of bolt and the female thread of circular shrinkage hole screw identical, jackscrew
Inner cone compresses the nuts of fixed gear ring downwards, prevents bolt looseness, is fixed on by hollow pin by bolt and jackscrew
In semicircle fixing hole, after hollow pin is fixing, can prevent in running up, the problem that gear ring moves up and down.

Detailed description of the invention
It is described with reference to this utility model is made detailed description in detail below.As shown in drawings, of the present utility model
Structure includes disk body 1, semicircle fixing hole 2, circular shrinkage hole 3, hollow pin 4, screw 5, gear ring 6, gland 7, imploded arcs 8, screw
A9, it is characterised in that be provided with semicircle fixing hole 2 on the inwall of disk body 1, the quantity of this semicircle fixing hole 2 be two and more than,
It is provided with circular shrinkage hole 3 on the bottom disc 1 of semicircle fixing hole 2, inside circular shrinkage hole 3, is provided with female thread, the sidewall of disk body 1
On be provided with screw 5, the disk body 1 below screw 5 is provided with screw A9, it is solid that this screw 5 is through to semicircle from the sidewall of disk body 1
Determine in hole 2, screw 5 and semicircle fixing hole 2 degree in a vertical angle, gear ring 6 is installed in disk body 1, the cylindrical of gear ring 6 is provided with indent
Arc 8, the longitudinally height of imploded arcs 8 is less than the longitudinally height of gear ring 6, and the bottom of imploded arcs 8 is higher than the bottom of gear ring 6, and semicircle is solid
By bolt, hollow pin 4 is installed in determining hole 2, jackscrew is installed in screw 5, the external screw thread of bolt and circular shrinkage hole 3 interior
Screw thread screws identical, and the inner cone of jackscrew compresses the nuts in screw 5 downwards, by bolt and jackscrew by hollow pin 4
It is fixed in semicircle fixing hole 2, and the imploded arcs 8 of gear ring 6 cylindrical reaches the purpose of fixed gear ring 6.
Operation principle: insert in semicircle fixing hole 2 by hollow pin 4, inserts bolt in hollow pin 4, passes through bolt
External screw thread and the female thread of circular shrinkage hole 3 screw identical, hollow pin 4, through after the imploded arcs 8 of gear ring 6 side, is suppressed
