Abstract
The utility model provides a lathe elastic wrench, which can effectively prevent a wrench from a chuck in use so as to avoid lathe false tripping and to avoid personal injury and lathe damage caused by the chuck wrench. The wrench comprises a wrench body, a wrench rod and a sleeve; the wrench rod is arranged at one end of the wrench body, and the other end of the wrench body is a square head; one end of the square head of the wrench body penetrates into the sleeve; the portion of the wrench body extending in the sleeve is sleeved with a support spring. In use, the spring does not need to be compressed by force; after use, the spring is slightly loosened and the square head of the wrench body is ejected from a chuck square hole under the effect of elastic force, so that the wrench body is separated from the surface of the chuck, thereby avoiding lathe false tripping caused by carelessness and personal injury and lathe damage caused by the chuck wrench. The lathe elastic wrench is safe and convenient to use and has a simple structure.
Description
Technical field
The utility model belongs to technical field of tools, relates in particular to a kind of lathe elastic wrench.
Background technology
At present, known chuck for lathe spanner is all a wrenching bar and wrench body composition, clamps or unclamps after workpiece, does not sometimes take out spanner and the accident that chuck handle is hurted sb.'s feelings or damaged machine tool easily occurs careless and inadvertent error starting lathe.So existing spanner is transformed, add sleeved and spring, play safeguard protection effect.
Summary of the invention
Utility model object: the utility model provides a kind of lathe elastic wrench, its objective is in order to prevent unsafe factor, overcome that existing spanner is easily hurted sb.'s feelings and damage equipment deficiency.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of lathe elastic wrench, is characterized in that: this spanner comprises wrench body, wrenching bar and sleeve; Wrenching bar is arranged on one end of wrench body, and the other end of wrench body is square toes, and sleeve is pierced in one end of the square toes of wrench body, and wrench body puts in cover in the part in sleeve support spring.
One end and the sleeve lining of support spring are fixed, and the other end withstands wrench body.
The square toes of wrench body stretch out sleeve while using, during end under the effect of support spring indentation sleeve.
Support spring is cylindrical screw compression bullet.
On wrench body, be provided with portion with external threads, sleeve lining is provided with part internal thread, and when wrench body and sleeve are installed, the internal thread that the external screw thread on wrench body was twisted sleeve lining makes the external screw thread of wrench body withstand on the internal thread upper limit of sleeve lining.
Advantage and effect: the utility model provides and in a kind of use, can effectively prevent spanner on chuck and error starting lathe generation chuck handle is hurted sb.'s feelings or damage the accident of machine tool.This spanner comprises wrench body, wrenching bar and sleeve; Wrenching bar is arranged on one end of wrench body, and the other end of wrench body is square toes, and sleeve is pierced in one end of the square toes of wrench body, and wrench body puts in cover in the part in sleeve support spring.
The beneficial effects of the utility model are, Compress Spring with strength during use, when finishing using, need only trip spring a little, wrench body square toes will eject under the effect of elastic force in chuck square hole, wrench body and chuck surface are departed from, prevent negligence and error starting lathe, the accident that chuck handle is hurted sb.'s feelings or damaged machine tool occurs.Use safety, convenient, simple in structure.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model provides a kind of lathe elastic wrench, and this spanner comprises wrench body 2, wrenching bar 1 and sleeve 4; Wrenching bar 1 is arranged on one end of wrench body 2, and the other end of wrench body is square toes, and sleeve 4 is pierced in one end of the square toes of wrench body, and wrench body puts in cover in the part in sleeve support spring 3.
One end and the sleeve lining of support spring 3 are fixed, and the other end withstands wrench body.
The square toes of wrench body 2 stretch out sleeve 4 while using, during end under the effect of support spring indentation sleeve.As shown in Figure 1, while not using, square toes be contracting in sleeve 4 or protrude from a little sleeve 4 can.
Support spring is cylindrical screw compression bullet.
On wrench body, be provided with portion with external threads, sleeve lining is provided with part internal thread, and when wrench body and sleeve are installed, the internal thread that the external screw thread on wrench body was twisted sleeve lining makes the external screw thread of wrench body withstand on the internal thread upper limit of sleeve lining.Specifically, exactly wrench body being put in to sleeve installs, when contacting with internal thread of sleeve, the external screw thread of wrench body screws wrench body or sleeve, because wrench body and sleeve are all part screw threads, the external screw thread of wrench body can enter internal thread of sleeve then gradually through internal thread of sleeve along with screwing, and in the end the external screw thread of wrench body departs from internal thread of sleeve, thereby make internal thread of sleeve block the internal thread of wrench body, wrench body cannot directly be pulled out in sleeve.
The utility model in use, by there being one end of square toes on wrench body, aim at the cubic hole of chuck, exert pressure a little, wrench body will compress support spring, make the square toes of wrench body fill in hole, lathe chuck four directions, and now, sleeve withstands on around cubic hole, rotary spanner bar 1 afterwards, thereby locking or unclamp workpiece, when after EO, unclamp a little the pressure of wrench body, wrench body square toes will be drawn out indentation sleeve under the elastic force effect of support spring in chuck square hole, wrench body and chuck surface are departed from, prevent negligence and error starting lathe, there is the accident that chuck handle is hurted sb.'s feelings or damaged machine tool.
The utility model is rational in infrastructure, uses and finishes rear automatic spring, makes the square toes of wrench body automatic separation with workpiece, prevents from forgetting the accident that wrench body causes of taking out.
