Abstract
The utility model discloses a withdraw-free wrench, which comprises a handle bar 1 and a wrench head 2. The wrench is characterized in that two grooves are arranged in an outer ring hole of the wrench head 2, wherein a projection is arranged on one groove, the projection portion is connected with one end of a spring 5, the other end of the spring 5 is connected with a card 4, one face of the card 4 is provided with teeth which are meshed with teeth on the external surface of a gear 3, and the gear 3 is moveably connected with the wrench head 2 through a snap spring 6. The wrench has the beneficial effects that the wrench does not need to repeatedly draw out or insert, the wrench can be directly blocked on workpieces to rotate to the required position in order to screw up and loosen workpieces, the time is saved, and convenience and fastness are felt especially when workpieces are not easy to observe or obstacles occur.
Description
Technical field
The utility model relates to a kind of machine tool, particularly a kind ofly exempts to withdraw from spanner.
Background technology
We often use spanner to tighten or pine is unloaded screw and nut.Existing monkey wrench, fork spanner box spanner need transposition repeatedly in slack adjuster or nut process, just need spanner is extracted out, waste time and energy so repeatedly in that its bayonet socket alignment screw or nut are inserted in the rotation back.Particularly when screw or nut when being difficult for the position of observing, the spanner bayonet socket just more is difficult to alignment screw or nut.Though the pipe spanner need not contraposition repeatedly when slack adjuster or nut, must there be bigger space just can use around screw or the nut.
Summary of the invention
At the shortcoming of existing spanner, the utility model provide a kind of novel can directly be stuck in pull back and forth on screw or the nut exempt to withdraw from spanner.
To achieve these goals, the measure taked of the utility model:
A kind ofly exempt to withdraw from spanner, comprise handle 1 and driving end 2, handle 1 and driving end 2 are the Contiuum type structure, be provided with two grooves in the cycle hole of described driving end 2, one of them groove is provided with a projection, and bossing is connected with an end of spring 5, and the other end of spring 5 is connected with fastener 4, the one side of fastener 4 abuts against on the cycle hole inwall of driving end 2, and another side is provided with tooth and meshes with the tooth that reeded gear 3 outer surfaces are set; The inwall of jump ring 6 is close on the groove of gear 3, and outer surface is close on the groove in the cycle hole of driving end 2, and gear 3 flexibly connects by jump ring 6 with driving end 2.
The beneficial effects of the utility model: need not spanner extraction is repeatedly inserted, spanner can directly be stuck in and return back to desired location on the workpiece and tighten with pine and unload, and saves time, and particularly outstanding sense is convenient and quick when workpiece is difficult for observing or obstacle is arranged.

The specific embodiment
A kind ofly exempt to withdraw from spanner, comprise handle 1 and driving end 2, handle 1 and driving end 2 are the Contiuum type structure, be provided with two grooves in the cycle hole of described driving end 2, one of them groove is provided with a projection, and bossing is connected with an end of spring 5, and the other end of spring 5 is connected with fastener 4, the one side of fastener 4 abuts against on the cycle hole inwall of driving end 2, and another side is provided with tooth and meshes with the tooth that reeded gear 3 outer surfaces are set; The inwall of jump ring 6 is close on the groove of gear 3, and outer surface is close on the groove in the cycle hole of driving end 2, and gear 3 flexibly connects by jump ring 6 with driving end 2.In use, directly be stuck in driving end 2 on the workpiece, hold handle 1 and rotate, under the effect of fastener 4, gear 3 is fixed, when needs are adjusted the spanner position, need not spanner is extracted out, only need hold handle 1 revolution, because the tooth of tooth on the fastener 4 and gear 3 outer surfaces meshes, this moment, gear 3 was also turned round, thereby blocked workpiece again.The beneficial effects of the utility model: need not spanner extraction is repeatedly inserted, spanner can directly be stuck in and return back to desired location on the workpiece and tighten with pine and unload, and saves time, and particularly outstanding sense is convenient and quick when workpiece is difficult for observing or obstacle is arranged.
Those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in this area.
