Description

[Detailed Description of the Invention] The present invention relates to a wrench adapter that is fitted onto the outer periphery of a change knob of an automobile and screwed into the change lever or the like.

Generally, a column shift type change knob is screwed into the change lever elsewhere and assembled into a car on the car assembly line as a single part.

Therefore, when screwing the change knob into the change lever,
A worker wraps a cloth to protect the knob around the knob, fits a cylindrical socket around it, and tightens it to the change lever with a tool such as a spanner or adjustable wrench. The screws sometimes rotate idle between the screws and the sockets, resulting in poor work efficiency, and each time a screw is screwed in, it is necessary to wrap it with cloth, making the work complicated.

The present invention solves this problem by fitting a cylindrical socket onto the change knob, and pressing the change knob with an abbreviated suppressing member that is rotatably supported in a plane that includes the axis of the socket. Tightening is done by screwing in with a tool.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

Reference numeral 1 denotes a wrench adapter, and 2 a cylindrical socket. Rubber 3 is pasted on the inner periphery to protect the change knob A from being damaged, and an opening hole 4 is formed on the side.

A notch 6 is provided in the head 5 of the socket 2 and is in series with the opening hole 4 in the axial force direction of the socket 2.

Reference numeral 7 denotes a suppressing member having an abbreviated shape and disposed across the side of the socket and the head 5.

The pressing member 7 is supported by a pin 8 on the socket 2 at a notch 90 so as to be rotatable within a plane including the axis of the socket 2, and one end is pressed against the side of the change knob A through the opening hole 4. An inwardly bent suppressing portion 9 is formed at the other end thereof, and an inwardly bent abutment portion 10 is formed at the other end of the socket 2 so as to come into contact with the head portion of the change knob A from the head 5 side.

Rubbers 11 and 12 for protecting the change knob are attached to the tips of the pressing portion 9 and the contact portion 10.

A wrench fitting member 13 having a wrench fitting portion 14 into which a spanner, adjustable wrench, etc. can be fitted is integrally attached to the head 5 of the socket 20 with a bolt 15.

A spring 16 is interposed between the rear part of the contact part 10 of the pressing member 7 and the inside of the wrench fitting member 13 to bias the contact part 10 against the internal force of the socket 2.

Consisting of the above configuration, first, change knob A is temporarily tightened to change lever B.

Next, when the socket 2 is inserted into the change knob A, the head of the change knob A comes into contact with the abutment part 10 of the pressing member 7, and the suppressing member 7 rotates against the spring 16 (clockwise in the figure). direction) and press the side of the change knob A with the pressing part 9 of the pressing member 7.

As a result, the change knob A is attached to the inner periphery of the socket 2, pressed against the tacom 3, and gripped by the socket 2 and the pressing member 7.

Next, for tightening, such as a spanner, a tool is fitted into the wrench fitting part 14 of the wrench fitting member 13, and the socket 2 is rotated and screwed into the change knob A' and fixed.

In the above embodiment, the screwing of a column shift type change knob was explained, but it can also be used for screwing and tightening a floor shift type change knob or various lever knobs having a spherical or curved cylindrical shape.

As explained above, the present invention is capable of reliably gripping various knobs having a circular cross section, and it is extremely easy to screw the knobs into the lever, resulting in a marked improvement in workability.

It also has the effect of not damaging the knob surface during tightening.
