[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a nut holding tool used to hold a nut by inserting it into a gap where a tool such as a box wrench or box driver for holding the nut does not fit.

[0002]

[Prior art]

 With the miniaturization of the equipment, the space for attaching and detaching bolts and nuts is restricted, and it may be difficult to insert and hold the nuts in narrow places. In the past, a window had to be formed in the outer plate, case, board, or the like, for inserting and holding a finger in a narrow gap or for inserting a box driver in the nut holding position. However, when the nut is held with fingers, the reach of the nut is limited, and it is not possible to hold the nut in a deep gap. There was a problem that restrictions were imposed. To solve such a drawback, there is a "nut holding device for clearance" disclosed in Japanese Utility Model Publication No. 6-44603.

[0003] The nut can be efficiently tightened by holding the nut in a narrow gap. The nut is configured to hold the nut inserted from the base end at the tip so as to regulate the rotation of the nut. A nut and a nut escape opening which is opened at the front of the nut holding cylinder so as to include a screw hole of the nut locked at the tip, and holds the nut at the tip of the nut holding cylinder; The nut holding cylinder is moved up, down, left and right while the bolt is screwed in from the nut exit side, and the nut escapes from the nut exit port.

[0004]

[Problems to be solved by the invention]

 According to such a device, the nut can be efficiently tightened while holding the nut in a narrow gap.Therefore, it is necessary to form a window through which a box driver for holding the nut passes through the outer plate or case. This has the advantage that the arrangement of parts is not restricted. However, this clearance nut holding device can only handle bolts perpendicular to the longitudinal direction of the device, and the inner width of the nut holding cylinder must be adjusted to prevent rotation of the nut when screwing the bolt into the nut. There is a problem that the nut size that can be stored in the nut holding cylinder is limited because it is formed according to the short diameter.

The present invention provides a nut holding tool capable of holding a nut in a narrow gap and improving the efficiency of bolt tightening work without much restriction on the mounting direction of the nut, and capable of supporting a plurality of types of nut sizes. To provide.
