Description

[Detailed description of the invention] In this invention, one end of the handle 1 is rotatably supported by a support shaft 4 to a metal fitting 3 provided at the base of the shovel plate 2, and the outer periphery of the metal fitting 3 is attached in the direction of the tip of the shovel plate 2. A groove 5 in the opposite direction and a groove 6 in a direction substantially orthogonal to the groove 5 are formed, and a check tooth 7 is formed between the groove 6 in the orthogonal direction and the groove 5 in the opposite direction. A stop plate 9 is slidably fitted into the handle direction groove 8 formed in the grooves 5, 6 and the check teeth 7 so as to be able to engage and disengage, and a sliding device 10 for the stop plate 9 is provided. It is about a shovel.

The handle 1 is formed of a hollow tube, and a slidable rod 1 is installed inside the handle.
2 is built in, one end of the company 12 is connected to the stop plate 9, the other end is exposed inside the grip ring 13 provided at the other end of the handle 1, a grip part 14 is provided at the exposed end, and the handle 1 is connected to the stop plate 9. A spring 11 is interposed between the other end closing plate 15 and a flange 16 provided on the slidable rod 12, and a sliding device 10 is provided at the other end of the handle 1 (see FIG. 1).

The metal fitting 3 is a metal fitting 2 formed at one end of the handle 1 as shown in FIG.
A pair of metal fittings 3, 3 may be interposed between the crotches 1a, 1a, or may be provided on both sides of one end of the handle 1, as shown in FIG.

This metal fitting 3 is provided on the inner surface of the base of the shovel plate 2, and the inner surface of the shovel plate 2 is bent and reinforced in a V-shape on both sides of the center line a.

A groove 17 is provided on the outer periphery of the metal fitting 3 in the direction toward the tip of the shovel plate 2, and the number of non-return teeth 7 is two or two as shown in FIG.
Form three pieces as shown in the figure.

Note that the reference numeral 18 in the figure is a fixing screw for the metal fitting 3.

Therefore, the handle 1 is hung down, the grip ring 13 and the grip part 14 are gripped, and the stop plate 9 is slid along the groove 8 through the slidable rod 12 against the spring 11, and the above-mentioned setting grooves 5.6 and When removed from the check teeth 7, the shovel plate 2 hangs down around the support shaft 4.

In this state, when the grip part 14 is loosened, the stop plate 9 will release the spring 1.
The stop plate 9 slides down along the groove 8 with a force of 7, and the stop plate 9 engages with the groove 5 in the opposite direction, so that it can be used as an ordinary shovel to dig a hole 19 in the ground, as shown by the solid line in Figure 4. .

Then, insert the shovel plate 2 into the hole 19 as shown in FIG.
is inserted into the excavation ±20, the grip part 14 is gripped upward by hand or loosened, the stop plate 9 is raised and lowered, and the handle 1 is rotated back and forth about the support shaft 4 in the direction of the arrow. The stop plate 9 sequentially engages and disengages from the groove 5 and the check teeth 7, so that the included angle between the handle 1 and the shovel plate 2 is as shown in FIG.

As shown in Figures C, 2, and E, it is reduced and engaged with the groove 6, and the included angle becomes approximately 90 degrees. It can be taken outside.

Further, the handle 1 and the shovel plate 2 can be used as a hoe by keeping the included angle at about 90 degrees.

Conventionally, the shovel handle 1 and the shovel plate 2 are either fixed type or foldable type, but they have the drawback that it is difficult to reduce the above-mentioned included angle during excavation, it is difficult to easily excavate a small diameter deep hole 19, and it is difficult to use it in a conical shape. was there.

This proposal was developed in view of the above-mentioned defects, and since the present proposal is constructed as described above, the included angle can be easily reduced during excavation as shown in FIG. 5, and a small-diameter deep hole 19 can be excavated very easily. Moreover, not only can the excavated material ±20mm be easily discharged from the hole 19, but also it can be used as a hoe, and the structure can sufficiently withstand strong impacts, so it has the advantage of increasing durability and significantly improving work efficiency. There is.
