Description

  The present invention relates to a tap attachment that allows a head to tighten or loosen a square bolt. More specifically, the head can be tightened or loosened by attaching it to a socket wrench, ratchet wrench or spectacle wrench. It relates to tap attachment.

  When fastening machine parts, bolts with hexagonal heads (hexagonal bolts) or bolts with hexagonal holes formed in the head (hexagonal bolts) are often used. A bolt with a square head (square bolt) may be used to prevent a necessary part or easy removal.

  The square bolt has an advantage that the head is not easily crushed as compared with a hexagon bolt constituted by a hexagonal column because the head is constituted by a square column. Such screw tightening of square bolts is generally performed by a T-type square box wrench. By tightening the square bolt with a T-shaped square box wrench, it can be tightened with a higher torque than the hexagon bolt, so that it can be firmly fixed.

  The T-type square box wrench requires a sufficient work space in the axial direction of the screw when tightening the screw, and may not be able to work in a closed place. Therefore, as a method that does not require a work space, Patent Document 1 (Japanese Patent Application Laid-Open No. 2011-56653) discloses a technique for tightening the above-mentioned square bolt with a ratchet wrench.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2011-56653) discloses an adapter for performing screw tightening of the square bolts with a ratchet wrench. This ratchet wrench adapter attaches a wing nut and flat washer from the upper side of the ratchet wrench socket, and from the lower side of the ratchet wrench socket, the wing nut, flat washer, full screw bolt, regular hexagonal column, thin disc, square It is united by attaching a prism.

  By applying the adapter disclosed in Patent Document 1 to a ratchet wrench, bolts with holes of any shape can be screwed. In addition, there is an advantage that the manufacturing cost of the adapter is lower than that of the ratchet handle, the spectacle wrench and the spanner.

JP 2011-056553 A

  However, the adapter having the shape disclosed in Patent Document 1 has a problem that it is troublesome to attach the adapter to the ratchet wrench.

  The present invention has been made to solve the above-mentioned problems, and the object of the present invention is to easily attach to a socket wrench, ratchet wrench, spanner ratchet wrench, or spectacle wrench, and a square head. The present invention provides a tap attachment that can be easily tightened or loosened.

  In order to achieve the above object, the tap attachment of the present invention is a quadrangular prism that can be fitted into a socket wrench or ratchet wrench socket or spectacle wrench mounting hole and has an outer shape of a hexagonal column that penetrates the front and back sides A hole is formed.

  Since the tap attachment of the present invention has a hexagonal column shape, the tap attachment can be fitted into a socket wrench, a ratchet wrench, a socket of a spanner ratchet wrench, or a mounting hole of a spectacle wrench. By fitting the tap attachment of the present invention in this way, the cross-sectional shape of the socket wrench or ratchet wrench socket and the spectacle wrench mounting hole can be converted from a hexagon to a quadrangle. Accordingly, it is possible to easily tighten or loosen the bolt (each bolt) whose head is a square pillar with a socket wrench, a ratchet wrench or a spectacle wrench. Since the tap attachment of the present invention is smaller than a conventional T-shaped square box wrench, for example, it is possible to cope with tightening or loosening the bolts of the bolts of the square pillars only by placing them in the ratchet box.

It is the perspective view (A) and top view (B) of the tap attachment of this invention. It is the top view (A) and side view (B) which show the state which attached the tap attachment of this invention to the socket of the socket wrench. It is the top view (A) and side view (B) which show the state which attached the tap attachment of this invention to the attachment hole of the spectacles wrench. It is the top view (A) and side view (B) which show the state which attached the tap attachment of this invention to the socket of the ratchet wrench. It is the top view (A) and side view (B) which show the state which attached the tap attachment of this invention to the socket of the spanner ratchet wrench.

  In the following, features and structures of preferred embodiments of the present invention will be described with reference to the drawings.
