[0002]

2. Description of the Related Art In a conventional driver, when performing screw tightening work in a dark place such as outdoors, it is necessary to separately prepare lighting means such as a flashlight, which may be inconvenient in use. In addition, screw tightening work with a screwdriver is basically done by lightly grasping the shaft part with one hand and positioning it while rotating the handle part with the other hand, so holding the flashlight with one hand There was a problem that it was difficult to tighten the screws by hand.

As a means for solving the above problems,
For example, it is conceivable that a driver's handle has a built-in illuminating means such as a bean ball and the light of the bean ball is applied to the blade tip portion or its vicinity.

However, the driver provided with this means has the following problems. ． The built-in lighting means such as a mini ball complicates the structure of the handle portion of the driver, resulting in high cost. ． Lighting means such as miniature balls must be built into each driver. ． When using a screwdriver, the driver's head may be hit with a hammer while the blade tip is in contact with the head groove of the screw to increase the engagement between the blade tip and the head groove. Impact force may be applied almost directly to the miniature ball or electric wire, which may cause damage.

Therefore, in the industry that manufactures and sells tools, it can be applied to drivers of different types and shaft diameters at low cost, and means for developing a means for preventing the illumination means from being damaged even if the driver head is hit with a mallet. I'm looking forward to that.

BEST MODE FOR CARRYING OUT THE INVENTION A pen-shaped light attachment holder for a driver according to an embodiment of the present invention will be described below with reference to the drawings. [Embodiment 1] FIG. 1 is a perspective view showing a state in which a pen-shaped light mounting holder 1 for a driver according to an embodiment of the present invention holds a pen-shaped light 8 and a shaft portion 90 having a round cross section, and the driver. Pen type light attachment holder 1
FIG. (Regarding Configuration of Driver Pen-shaped Light Mounting Holder 1) The driver pen-shaped light mounting holder 1 is composed of a pen-shaped light holding portion 2 and a driver holding portion 3 as shown in FIGS. 1 and 2. Cage,
It is integrally formed of a known elastic synthetic resin.

As shown in FIGS. 1 to 3, the pen-shaped light holding portion 2 has a length slightly shorter than the length of the pen-shaped light 8 and a width slightly larger than the diameter of the pen-shaped light 8. A groove 2 for detachably holding the pen-shaped light 8 is provided on the side opposite to the driver holding portion 3.
0 (corresponding to the holding portion described in the column of means for solving the problem) is formed.

As shown in FIG. 3, the groove portion 20 is formed so as to match the outer peripheral surface of the pen-shaped light 8 and is set so that the central axis 8J of the pen-shaped light 8 reaches the groove portion. The width W2 of the open portion of the groove 20 is made slightly smaller than the diameter D2 of the pen-shaped light 8.

Therefore, in order to hold the pen-shaped light 8 in the pen-shaped light holding portion 2, the pen-shaped light 8 is forcibly pushed in according to the lengthwise direction of the groove 20. Since the holder 1 is entirely made of elastic synthetic resin, the width W2 of the open portion of the groove 20 is widened by the pen light 8 at the time of pushing, and then the diameter D2 of the pen light 8 passes gradually. In addition, the width W2 of the open portion becomes smaller than the diameter D2. For this reason, the pen-shaped light 8 is held in the pen-shaped light holding portion 2 in a retaining state, and will not accidentally fall off during screw tightening work. On the contrary, when removing the pen-shaped light 8 from the pen-shaped light holding portion 2, the pen-shaped light 8 may be forcibly pulled out.

As shown in FIGS. 1 to 3, the driver holding portion 3 has its length set (35 to 40 mm) in accordance with a driver having a short shaft portion, and the width thereof corresponds to the diameter of the shaft portion 90. The groove portion 30 for holding the shaft portion 90 of the driver 9 rotatably and detachably is provided on the side opposite to the pen-shaped light holding portion 2 (described in the column of means for solving the problem). (Corresponding to the shaft holding part).

As shown in FIG. 3, the groove portion 30 is for holding the shaft portion 90 having a diameter of 6.4 mm, and is set to a depth such that the central axis 9J of the shaft portion 90 reaches the groove portion. In addition, the width W3 of the open portion of the groove 30 is made slightly smaller than the diameter D3 of the pen-shaped light 8.

Therefore, the shaft portion 90 can be attached to and detached from the driver holding portion 3 in the same manner as in the case where the pen type light 8 is attached to and detached from the pen type light holding portion 2.

Further, when the shaft portion 90 is held by the driver holding portion 3, the shaft portion 90 partially contacts the groove portion 30, but since the groove portion 30 is made of resin, it is relatively frictional. The force is small and the driver 9 rotates smoothly.

Here, in this embodiment, the groove portions 20 and 3 are formed.
The extending direction of 0 is set to the same direction as shown in FIGS. 1 and 2, and the pen-shaped light 8 and the shaft portion 90 of the driver 9 shown in FIG. And the shaft 90 are substantially parallel to each other. (About the excellent function of the pen-shaped light attachment holder 1 for driver). When the pen-shaped light attachment holder 1 for a driver is used, as shown in FIG. 1, the pen-shaped light 8 is fitted into the groove portion 20, and the shaft portion 90 of the driver 9 is fitted into the groove portion 30 and held as described above. Let During the screw tightening work, the pen-shaped light 8 is turned on, the holder 1 is gripped by one hand, and the handle 92 of the driver 9 is rotated by the other hand.
