Abstract

The utility model discloses a kind of chuck handle, comprise wrench body (3), first spring (6), sleeve (4), described wrench body (3) upper end is provided with first handle (2), its lower end is provided with square head (5), described wrench body (3) lower outside is provided with the upper limit step (7) of annular, it is outside that described sleeve (4) is set in wrench body (3), described sleeve (4) upper end is provided with second handle (1), described sleeve (4) inboard bottom is provided with the lower limit step (8) of annular, described first spring (6) is sheathed in the wrench body between upper limit step (7) and lower limit step (8), the internal diameter of described lower limit step (8) is greater than the external diameter of square head (5).The utility model structure is simple, can effectively avoid passing into silence the security incident caused on chuck because of chuck handle.

Description

Chuck handle

Technical field

The utility model relates to field of machining, is specifically related to a kind of chuck handle.

Background technology

In Tutrning Process, chuck handle can be forgotten on chuck by operating personnel often, very easily causes security incident like this in lathe running.

Utility model content

For above-mentioned prior art Problems existing, the utility model provides a kind of chuck handle, and its structure is simple, can effectively avoid passing into silence the security incident caused on chuck because of chuck handle.

To achieve these goals, the utility model provides a kind of chuck handle, comprise wrench body, first spring, sleeve, described wrench body upper end is provided with first handle, its lower end is provided with square head, described wrench body lower outside is provided with the upper limit step of annular, described jacket casing is located at wrench body outside, described sleeve upper end is provided with second handle, the inboard bottom of described sleeve is provided with the lower limit step of annular, described first spring housing is located in the wrench body between upper limit step and lower limit step, the internal diameter of described lower limit step is greater than the external diameter of square head.

In this technical scheme, by making to be provided with sleeve outside wrench body, and outside wrench body, be provided with upper limit step, sleeve bottom end is provided with lower limit step, like this, when needs chuck handle operates chuck, make first handle and second handle close to each other, such square head can stretch out sleeve, just can operate chuck easily; After operating personnel terminate chuck operation, if forget when pulling up chuck handle, because external force is cancelled, such first spring can impel wrench body away from sleeve bottom, like this, chuck handle just automatically disengages chuck, just can avoid because the security incident caused on chuck forgotten by chuck handle.

Also comprise the second spring, described second spring housing to be located between first handle and second handle in wrench body.

In this technical scheme, by the setting of the second spring, can guarantee that, when external force disappears, wrench body is moved to the direction away from sleeve bottom rapidly further, thus can ensure that chuck handle and chuck depart from fast.

The position that the upper end of described second handle corresponds to first handle is provided with the chute that size is greater than first handle.

In this technical scheme, by the setting of chute, when operating, first handle can be made to fall into chute, chuck handle can be operated more easily like this.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of chuck handle, comprise wrench body 3, first spring 6, sleeve 4, described wrench body 3 upper end is provided with first handle 2, its lower end is provided with square head 5, described wrench body 3 lower outside is provided with the upper limit step 7 of annular, it is outside that described sleeve 4 is set in wrench body 3, described sleeve 4 upper end is provided with second handle 1, the described inboard bottom of sleeve 4 is provided with the lower limit step 8 of annular, described first spring 6 is sheathed in the wrench body between upper limit step 7 and lower limit step 8, the internal diameter of described lower limit step 8 is greater than the external diameter of square head 5.By making to be provided with sleeve 4 outside wrench body 3, and outside wrench body 3, be provided with upper limit step 7, sleeve 4 bottom is provided with lower limit step 8, like this, when needs chuck handle operates chuck, make first handle 2 and second handle 1 close to each other, such square head 5 can stretch out sleeve 4, just can operate chuck easily; After operating personnel terminate chuck operation, if forget when pulling up chuck handle, because external force is cancelled, such first spring 6 can impel wrench body 3 away from bottom sleeve 4, like this, chuck handle just automatically disengages chuck, just can avoid because the security incident caused on chuck forgotten by chuck handle.

Also comprise the second spring 9, described second spring 9 to be sheathed between first handle 2 and second handle 1 in wrench body 3.By the setting of the second spring 9, can guarantee when external force disappears further, wrench body 3 is moved to away from the direction bottom sleeve 4 rapidly, thus can ensure that chuck handle and chuck depart from fast.

As shown in Figure 2, the upper end of described second handle 1 corresponds to the position of first handle 2 and is provided with the chute 10 that size is greater than first handle 2.By the setting of chute 10, when operating, first handle 2 can be made to fall into chute, chuck handle can be operated more easily like this.
