Abstract

The utility model provides an easily-separable sleeve head which consists of a body. One end of the body is a connecting and fixing end, the inner cavity of the other end is a screwing head, and an elastic ejecting device of which the elastic force is adjustable is arranged in the inner cavity of the body. As the sleeve head is provided with the elastic ejecting device, an unscrewed bolt or nut is guaranteed to be separated from the sleeve head under the action of the elastic force, thereby preventing the bolt or nut from being left inside the sleeve head.

Description

Easily separated collet head
Technical field
The utility model is to twist bolt or the equipment of nut or the collet head of device.
Background technology
Existing sleeve head structure is to be connected and fixed end 2 at an end of body 1 as shown in Figure 1, is to twist 3 at the other end inner chamber of body 1.The occasion of unscrewing that this collet head is used in bolt (nut) easily causes bolt (nut) to stay in the sleeve, can not separate.
Summary of the invention
In order to solve the problem of easily staying after bolt or nut are unscrewed in the collet head, the utility model proposes easily separated collet head, comprise body, end at body is to be connected and fixed end, other end inner chamber at body is to twist head, it is characterized in that: be provided with the adjustable elasticity liftout attachment of elastic force in the described chamber body.This collet head is provided with the elasticity liftout attachment, guarantees to separate with collet head under the effect of spring force after bolt or nut are unscrewed, and has avoided bolt or nut to stay situation in the collet head.
Description of drawings
Fig. 1 is the structural representation of existing collet head.
Fig. 2 is the structural representation of easily separated formula collet head.
The specific embodiment
The structure of structure of describing easily separated formula collet head in conjunction with Fig. 2 is as follows: easily separated collet head, comprise body 5, and be to be connected and fixed end 6 at an end of body 5, be to twist 7 at the other end inner chamber of body 1.In body 1 inner chamber, be provided with the adjustable elasticity liftout attachment of elastic force to eject bolt or the nut after unscrewing.
As shown in Figure 2, the elasticity liftout attachment that elastic force is adjustable is to constitute like this: be provided with in body 1 inner chamber to a stubborn push rod that 7 one ends stretch out 8, push rod 8 afterbodys are with compression spring 9, and compression spring 9 afterbodys are by nut 10 supportings that are spun in the chamber body.Push rod 8 is executive items of disengagement bolts or nut; Compression spring 9 output separating forces; Nut 10 is adjusted the precompression and the supporting compression spring 9 of compression spring.

Claims (2)
