PURPOSE: To provide a tool fitting grip handle body capable of preventing fallout of a grip of a tool from its grip inserting hole. CONSTITUTION: In a tool fitting handle body 2 provided with a grip inserting hole 7 for receiving a grip 1a of a tool 1, a flexible projection part 4 which is adapted to abut on the surface of the grip 1a when the grip 1a of the tool 1 is inserted into the grip inserting hole 7, and thus to prevent sliding of the grip 1a, is provided in place on the inside surface of the grip inserting hole 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grip handle for mounting a tool.

[0002]

2. Description of the Related Art Conventionally, various grip handle bodies for inserting a grip handle of a tool have been proposed for the purpose of obtaining a strong tightening force for a tool such as a compact screwdriver. However, if the size of the handle is slightly different, or if the handle is frequently removed, the handle may fall out from the tool-fitting handle body.

In order to solve the above-mentioned drawbacks, the applicant of the present invention has devised Japanese Utility Model Laid-Open No. 3-103167 in which the grip of the tool does not fall off from the grip for mounting the tool (hereinafter referred to as a conventional example). ). However, upon various trials, the applicant of the present application confirmed that this conventional example is still insufficient, and completed the present application, which is a further improved invention of this conventional example.

[0004]

The gist of the present invention will be described with reference to the accompanying drawings.

A grip handle insertion hole 6 for inserting the grip handle 1a of the tool 1
It is a tool-fitting handle stalk body 2 provided with, and when the handle 1a of the tool 1 is inserted into the handle handle insertion hole 6, it can come into contact with the surface of the handle 1a and prevent the handle 1a from sliding. The present invention relates to a grip handle body for tool mounting, characterized in that the flexible convex portion 4 is provided at a proper position on the inner surface of the grip handle insertion hole 6.

In the grip handle for tool mounting according to claim 1, a grip member 3 made of synthetic resin is provided in a wound state on the outer periphery of the grip handle body 2 for tool mounting, and the grip member 3 and the flexibility are flexible. The present invention relates to a tool mounting grip body which is characterized in that the convex portion 4 is integrally formed.

The tool-mounting handle body according to claim 2, wherein the gripping member 3 is formed of a member having an appropriate flexibility.

[0008]

When the grip handle 1a of the tool 1 is inserted into the grip handle insertion hole 6 of the grip handle body 2 for mounting the tool, the flexible convex portion 4 comes into contact with the surface of the grip handle 1a. Sliding with respect to the handle handle insertion hole 6 is prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show one embodiment of the present invention.
This will be described below.

In this embodiment, the tool-mounting handle 2 is integrally formed of an appropriate synthetic resin member, and the tool-mounting handle 2 has a cross section for preventing slipping of the hand when gripped. Are formed to have a substantially triangular shape.

The tool-mounting handle 2 is composed of a synthetic resin cylindrical main body 2'and a synthetic resin gripping member 3 wound around the main body 2'and has a tip end axial direction. Is provided with a handle handle insertion hole 6 (having a substantially triangular shape in cross section) of a predetermined depth into which the handle 1a (having a substantially triangular shape) of the tool 1 (driver) is inserted.
Further, a grip handle insertion hole 7 (having a substantially triangular shape in cross section) having a predetermined depth into which the grip handle 1a of the tool 1 is fitted is also provided near the rear portion of the side surface.

The tool mounting grip body 2 is formed by a so-called double injection molding method, that is, a method of laminating the gripping member 3 after molding the main body 2 '. At this time, a part of the gripping member 3 is formed in a state of being fitted into the through hole 5 provided in the grip handle insertion holes 6 and 7 of the main body 2 ', and the gripping member 3 is locked to the main body 2'. When the resin is fixed and the resin flows into the through hole 5, the flexible convex portion 4
Is formed.

When the handle 1a of the tool 1 is inserted into the handle handle insertion hole 6, the tool 1 and the tool mounting handle body 2 become straight, and the handle handle 1a of the tool 1 is inserted into the handle handle insertion hole 7. When the tool is inserted, the tool 1 and the tool mounting handle 2 are T-shaped.

Since the present embodiment is constructed as described above, since the surface of the grip 1a of the tool 1 is pressed and locked by the flexible convex portion 4 which presses the grip 1a of the tool 1, the grip 1a is locked. The mating of the grip handle 1a with the grip handle insertion holes 6 and 7 is assured, and the grip handle 1a
And the handle patterns insertion holes 6 and 7 are slightly different in size, and even if the handle pattern 1a is frequently attached to and detached from the handle pattern insertion holes 6 and 7, the handle pattern 1a is inserted into the handle pattern insertion holes 6 and 7. 7 is surely prevented from falling off, and since the grip handle member 3 is present,
It is possible to prevent the hand gripping the tool mounting handle 2 from slipping, and since the flexible convex portion 4 is formed at the same time when the grip member 3 is formed, the manufacturing efficiency is improved.

[0015]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, it is possible to reliably prevent the grip handle of the tool inserted into the grip handle insertion hole of the tool handle grip handle from falling off. Become.
