った。[Industrial Field of Application] The present invention relates to a spanner used in tightening or loosening nuts. [Prior Art] Conventional devices of this type have been constructed so that a handle extends from the center of rotation in order to obtain torque for turning the nut. [Problems to be solved] According to the above conventional example, since the wrench is rotated by the handle, regardless of the required torque, if the wrench is rotated beyond a certain angle, there will be an 8-curve that will cause the wrench to be removed from the nut, reducing work efficiency. It was bad.

Fixed position as nut receiving part 5. [! It has a roughened periphery 6. Also, number 7 is Natsu. The operation when turning the nut 7 using the spanner 11 configured in this way is as follows. When the wrench 11 is moved and the nut 7 is relatively inserted into the fixed position 5 from the nut passageway 4, a pair of spring mechanisms 2Fi and a spring means (not shown) K are expanded against each other as shown in FIG. It will be opened. Thereafter, as shown in FIG. 3 (4), (Bl), the nut 7 is housed in the nut-to-fixed position 5, and the pair of spring mechanisms 2 return and are fixed by their claws 2a.
The wrench 11 will not be released unless a force is applied to pull it out, and the nut 7 can be tightened or loosened by turning the circumference 6 that has friction. With this structure, the nut 7 can be attached and detached with one touch, and the spanner 11 can be turned almost continuously with one hand without coming off the nut 7, resulting in high work efficiency. [Effects of the Invention] As explained above, the present invention stores a nut in a relatively large-shaped case without a handle to a fixed position through the nut passage, and prevents the nut from coming out using a pair of spring mechanisms. Because it is fixed in place, the nut can be turned continuously by holding the case, and there is no need to remove the wrench, which improves work efficiency and eliminates the risk of the nut coming off due to the spring mechanism mentioned above. This has the effect of further improving workability and being advantageous for relatively small-torque operations such as assembly work in machining and attachment/detachment work of high-frequency connectors used in communication equipment.
