Abstract

PURPOSE:To obtain a screwdriver by which lens are not scratched in using by forming a socket part wherein a square hole is formed on the tip, a shaft part extended from the socket part, wherein an irregular surface is formed on the outer periphery and a head part provided on the rear end of this shaft part by means of resin materials. CONSTITUTION:In a socket part 1 of a screwdriver, a hexagon socket 2 to be engaged with the outside of an extremely small nut is formed on the tip center, and a shaft part 3 taking its an irregular surface 4 wherein a plurality of flutes are provided on the outer peripheral surface as a non-skid part is extended on this socket part 1. And a head part 5 for pressing the screwdriver is formed on the rear end of this shaft part 3. And the socket part 1, the shaft part 3 and the head part 5 are integrally (independently) formed by resin materials (for example, resin including glass fiber). Thereby, the screwdriver is lightweight and easily handled, so as not to scratch lens in using.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screwdriver for spectacles used for tightening a very small nut with a low torque, for example, when fixing a lens of spectacles to a frame.

[0002]

2. Description of the Related Art For example, when assembling a lens of a spectacle and a frame, they are fixed using a tiny screw and a tiny nut, but a special metal wrench is used for assembling and disassembling them. ing.

[0003]

However, the screw tightening portion of the spectacles is often loosened during use,
The general user is often in trouble because there is no suitable tool to tighten it. In addition, although metal eyeglasses are used for repairs at eyeglass shops, the metal is expensive and has the drawback of damaging the lens by dropping or sliding the tool during use. However, there are issues such as being heavy to carry around. The present invention has been made with the object of solving these problems and providing an inexpensive resin screwdriver that does not damage the lens.

[0004]

In order to achieve this object, a socket portion having a square hole at the tip, a shaft portion extending from the socket portion and having an uneven surface on the outer periphery, and a rear end of the shaft portion are provided. A screwdriver for spectacles, which is formed of a resin material and a head provided on the.

[0005]

[Operation] Insert a tiny nut into the square hole 2 at the tip of the screwdriver,
By gripping the shaft portion 3 and the end surface of the head portion 5 with a finger and turning the non-slip uneven surface 4, the miniature nut can be tightened or removed. Further, since this screwdriver can be molded in a large amount and at a low cost using a resin material, it can be easily obtained and carried by a general eyeglass user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the drawings. Figure 1
And FIG. 2 is a screwdriver for eyeglasses of the present invention. 1 in the figure
Is a socket portion, and a hexagonal hole 2 that engages with the outer shape of a very small nut is formed at the center of the tip. be able to. A shaft portion 3 extends from the socket portion 1, and an outer peripheral surface of the shaft portion 3 has an uneven surface 4 provided with a large number of vertical grooves.
It has become. The uneven surface 4 is a slip stopper for turning with a finger, and in the embodiment, a large number of vertical grooves are formed. A head portion 5 for pressing a screwdriver is formed at the rear end of the shaft portion 3, and the head portion 5 can be a separate component and can be freely rotated.
The socket portion 1, the shaft portion 3, and the head portion 5 are integrally molded (or separately formed) with a resin material (for example, resin containing glass fiber). Further, a company name, a tool size, etc. can be simultaneously formed on the shaft portion 3. This screwdriver is
For example, when fixing a lens of eyeglasses to a frame, it is most suitable for low torque tightening of an extremely small nut. It is possible to tighten or remove the micro nut by inserting the micro nut into the hexagonal hole 2 at the tip of the screwdriver, grasping the ring portion 3 and the end face of the head 5 with fingers, and turning the uneven surface 4 that has been subjected to slip prevention with fingers. it can. Further, since this screwdriver can be molded in a large amount and at a low cost using a resin material, it can be easily obtained and carried by a general eyeglass lover.

As is apparent from the above description, the present invention is
A socket part having a square hole at the tip, a shaft part extending from the socket part and having an uneven surface on the outer periphery, and a head part provided at the rear end of the shaft part are integrally molded with a resin material (or separately formed). It is a screwdriver for eyeglasses. According to the present invention, since the screwdriver is made of a resin material, it is light and easy to handle and does not damage the lens or the like during use. Further, since the shape is resin-moldable, it can be molded in large quantities and at low cost, and can be easily obtained and carried by eyeglass users as an accessory tool for eyeglasses. Also, since the company name and tool size can be indicated, many advantages such as convenience in handling can be obtained.
