Description

[Detailed Description of the Invention] The present invention relates to a winding device, and its purpose is to provide a device suitable for portable use.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall appearance, and FIG. 7 shows the inside. Reference numeral 1 indicates a central grip, 2 and 3 are caps, and 4 is a clip attached to the cap 3.

5 is a type 1 blade portion, and 6 is a 10 type blade portion.

The caps 2 and 3 are attached to the grip part 1 and can be removed freely, and FIG. 2 shows a state in which the cap 2 is removed and the type 1 blade part 5 is exposed.

In FIG. 5, 7 is a shaft having a rectangular cross section with blades 5.6 attached to both ends, and 8a, 8a are upright portions.

Step portions 5a and 6a are formed between the shaft 7 and the blade portions 5 and 6.

Although FIG. 6 shows only the gripping portion 1, a rectangular through hole 9 is formed in this, and the shaft 7 is slidably inserted therethrough.

Furthermore, a pair of kerf grooves 10a are connected to the through hole 9. 10b are formed facing each other, and the upright portions 8a, 8b are accommodated therein.

The assembled state of these parts is shown in FIG. 7, and the upright parts 8a and 8b are rotatably and erectably attached to the grooves 10a and 10b by support shafts 11a and llb, respectively.

Large protrusions 12a, 1 are provided at the ends of the standing parts 8a, 8b.
2b small protrusions 13a and 13b are attached.

On the other hand, first recesses 14a and 14b are formed on the side surface of the shaft 7 to the left of the center, and a second recess 15 is formed to the right.
a and 15b are formed.

Leaf springs 16a, 16b are attached to the bottoms of the second recesses 15a, 15b toward the center.

Further, each of the recesses is formed at a position slightly shifted from the side when viewed from the side so as not to deteriorate the strength of the shaft 7.

In the state shown in FIG. 7, the center portion of the shaft 7 is located within the grip portion 1, and the large protrusions 12a, 12b are engaged with the recesses 14a, 14b.

The small protrusions 13a and 13b are plate springs 16a and 16b.
is in contact with.

Therefore, the upright plate 8a is biased counterclockwise, and the upright plate 8b is biased clockwise.

Therefore, the shaft 7 and the gripping portion 1 maintain the above-mentioned positional relationship.

Next, the operation of the present invention in the above-described configuration will be explained.

First, as shown in FIG.
If the caps 2 and 3 are attached to the clips 4, the clips 4 can be held in a pocket of a shuffler or the like.

When using this as a - type screwdriver, the cap 2 is removed to expose the type 1 blade portion 5 as shown in FIG.

In this state, the small protrusions 13a, 13b of the upright parts 8a, 8b are in contact with the leaf springs 16a, 16b, and the large protrusions 12a, 12b are engaged with the first recesses 14a, 14b, as shown in FIG. Therefore, it is located within the kerf grooves 10a and 10b.

Next, as shown in FIG. 3, the shaft 7 is slid in the through hole 9 so as to pull out the type 1 blade part 5 from the grip part 1.

In this state, as shown in FIG.
are disengaged from the first recesses 14a, 14b, and the small protrusions 13a, 13b are moved to the second recess 15a.

15b.

Then, the back portions of the upright portions 8a and 8b are projected from the grip portion 1.

The above-mentioned sliding end position is determined by the step portion 6a coming into contact with the end surface of the gripping portion 1.

Thereafter, as shown in FIG. 4, the upright portion 8a is manually
, 8b upright at 90 degrees, with this - mold blade part 5
can be rotated with sufficient rotational force.

Since the shaft 7 and the through hole 9 are rectangular, the shaft 7 and the through hole 9 rotate together without rotating.

In this state, the ends 17a, 17b of the upright portions 8a, 8b are connected to the second recesses 15a, 15, as shown in FIG.
b, and this state is maintained by leaf springs 16a and 16b.

When using this mold blade part 5, a slight force is applied in the axial direction and the ends 17a and 17b try to disengage from the second recesses 15a and 15b, but the upright parts 8a and 8b are grasped. There is no possibility of this happening because it is held together with part 1 by hand.

After use, the upright portions 8a and 8b are manually brought down, the ends 17a and 17b are released from the second recesses 15a and 15b, and the center portion of the shaft 7 is located within the gripping portion 1. It draws me in.

As a result, the state returns to the state shown in FIGS. 2 and 7 again.

On the other hand, when using the green blade part 6, the cap 3 of that side
You can remove it and follow the same procedure as described above.

According to the present invention described above, the blade part can be fully pulled out from the grip part during use, so even if the screw is located deep, it is possible to fully turn the screw, and the blade part can be fully pulled out from the grip part. When the part is pulled out, the upright part for twisting operation automatically protrudes from the grip part in conjunction with this, making it easy to raise the upright part.

Further, when not in use, the blade part can be retracted toward the grip part to shorten the overall length of the screwdriver, and the upright part can be stored in the grip part, making it suitable for portable use.

In the embodiment of the present invention described above, a pair of upright parts are provided, but they may be provided in a single pair, and although the blade parts are provided at both ends of the shaft, only one may be provided. These configurations and shapes may be modified in various ways within the scope of achieving the objectives and effects of the present invention.
