External diameter more than bearing；Described ringfeder has axial groove, although this kind of operational approach solves dismounting bearing
Problem, but its structure is complicated, and its scope that can use is little, and the parts using location are nut, structure
Stability is the highest.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of simple in construction, is suitable for
Scope is wide, constitutionally stable tears bearing instrument open.
The purpose of this utility model is achieved in that
One tears bearing instrument open, and including screw rod, nut plate and claw, described claw is fixed on nut plate bottom,
Forming through hole in the middle part of claw, the internal diameter of through hole bottom is gradually reduced formation end difference from top to bottom, under claw
Plural opening is radially offered in end, offers annular groove in the middle part of claw outer wall；Described screw rod wears
In screwed hole in the middle part of nut plate, screw rod is threadeded with nut plate, and top is extended in screw rod lower end；Top
When head comes downwards to described end difference, top gradually struts described claw.
Described claw is provided with elastic component.
Described elastic component is annular resilient collar.
Described claw body outer diameter > dog rings connected in star bottom external diameter > annular groove external diameter.
The top sidewall of described screw rod is angled with axis.
Described nut plate outer side surface is provided with form friction pattern.
The top other end of described screw rod is provided with crank handle.
Described nut plate profile is polygon or circle.
This utility model highlights and useful having the technical effect that compared to existing technology
1, this utility model includes that screw rod, nut plate and claw, described claw are fixed on nut plate bottom, card
Forming through hole in the middle part of pawl, the internal diameter of through hole bottom is gradually reduced formation end difference, claw lower end from top to bottom
Portion radially offers plural opening, offers annular groove in the middle part of claw outer wall；Described screw rod is located in
In screwed hole in the middle part of nut plate, screw rod is threadeded with nut plate, and top is extended in screw rod lower end；Top
When coming downwards to described end difference, top gradually struts described claw, when rotating screw rod, holds nut plate,
Then top decline struts claw, thus annular groove clamping bearing, its simple in construction, can clamping smoothly
Bearing and taking-up bearing of taking advantage of a situation.
2, described claw of the present utility model is provided with elastic component, and described elastic component is preferably annular resilient collar,
Described elastic ring is used for the reset after claw struts and compression, it is ensured that the claw moment keeps the state compressed, bullet
Property circle the power that inwardly extrudes of claw is provided, it is ensured that the stability of structure.
3, described claw body outer diameter of the present utility model > dog rings connected in star bottom external diameter > annular groove
External diameter, it is simple to claw is convenient to be extend in bearing so that during clamping, location is more accurate, gripping is more
Add conveniently.
4, described nut plate outer of the present utility model is provided with form friction pattern, and described form friction pattern facilitates user to grasp
Make so that these innovation and creation more hommization.
5, described nut plate profile of the present utility model is polygon or circle, can according to the demand used more
Changing profile, applicable is wider.
