Abstract
A chuck wrench with three jaws is provided, which comprises a wrench body, a wrench handle and a spring connected with the wrench body. Compared with current ones, the chuck wrench with three jaw of the utility model automatically pops up from a square hole on the external circumference of the chuck with three jaws under the control of the spring to remind its users. As machine tools are started, it is unlikely to undergo the chuck fly-off from the square hole and avoid striking persons or objects around the wrench, thus preventing serious people's life and property loss.
Description
Technical field
The utility model relate generally to lathe jig specifically, relates to a kind of lathe scroll chuck spanner.
Background technology
At present, lathe comprises a wrench body and a spanner handle with the scroll chuck spanner, and the upper end of wrench body has a through hole, and the lower end of wrench body is the cylinder with square cross section.During use, earlier spanner handle is inserted in the through hole of wrench body upper end, again the lower end of wrench body is inserted in the square hole on the scroll chuck excircle, rotating spanner handle then, the gearing of the transmission mechanism by scroll chuck self, three claws of scroll chuck radially move back and forth, thereby realize the chucking of workpiece or loosen.Yet, the user is after using this scroll chuck spanner, often forget it is taken off from scroll chuck, when starting lathe, the scroll chuck spanner is under action of centrifugal force, fly out the square hole from the scroll chuck excircle, beat on the people or thing around, the people's life and property caused significant damage.
Summary of the invention
The utility model will solve the in use unsafe technical problem of scroll chuck spanner of prior art, and a kind of improved scroll chuck spanner is provided.
Scroll chuck spanner of the present utility model comprises a wrench body and a spanner handle, it is characterized in that, also comprise a spring, this spring housing is contained on the wrench body.
Scroll chuck spanner of the present utility model is compared with the scroll chuck spanner of prior art, because a spring housing is contained on the wrench body, the user is after using the scroll chuck spanner, under the effect of spring force, wrench body can automatically eject the square hole from the scroll chuck excircle, remind to the user, when starting lathe, take place never again to fly out the square hole of scroll chuck spanner from the scroll chuck excircle, beat on the people or thing around the phenomenon that the people's life and property caused significant damage.
Description of drawings
Fig. 1 is the perspective diagram of scroll chuck spanner of the present utility model.
The specific embodiment
For further specifying content of the present utility model, characteristics and effect, describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1, scroll chuck spanner of the present utility model comprises a wrench body 1, a spanner handle 2 and a spring 3.
Spanner handle 2 is cylindrical, uses the quality carbon steel manufacturing, and the mid portion that the through hole 15 of itself and wrench body 1 forms a fixed connection has the triangle dentation 21 of even branch on the periphery of spanner handle 2.
The mid portion of spanner handle 2 is pressed in the through hole 15 of wrench body 1 upper end, and the tip of the triangle dentation 21 on the periphery of spanner handle 2 produces distortion, forms a fixed connection with wrench body 1, becomes one.During use, under the situation of the diameter on the top 11 of wrench body 1 and the identical (not shown) of diameter at middle part 12, spring 3 is sleeved on the wrench body 1, the collar 31 of spring 3 contacts with spanner handle 2, or as shown in Figure 1, under the situation of diameter greater than the diameter at middle part 12 on the top 11 of wrench body 1, spring 3 is sleeved on the wrench body 1, the collar 31 of spring 3 contacts with annular shoulder 14, the bottom 13 of wrench body 1 is inserted in the square hole on the scroll chuck excircles, the rotating spanner handle 2 then again, the gearing of the transmission mechanism by scroll chuck self, three claws of scroll chuck radially move back and forth, thereby realize the chucking of workpiece or loosen.The user is after using the scroll chuck spanner, under the effect of spring force, wrench body can automatically eject the square hole from the scroll chuck excircle, remind to the user, when starting lathe, take place never again to fly out the square hole of scroll chuck spanner from the scroll chuck excircle, beat on the people or thing around, the phenomenon that the people's life and property caused significant damage.
The internal diameter of spring 3 collars 31 is slightly smaller than the internal diameter of other circle, and it is not broken away from wrench body 1.
For the not direct contacting metal of the hand that makes the user, can respectively put a plastic sheath 22 at the two ends of spanner handle 2.
