It is inconvenient to remove a large area of snow cover, while the latter is inconvenient for use in discarding snow mountain conditions collected in one location elsewhere.

A rake is used to collect fallen leaves, rice husks, and the like, but it is difficult to use a rake to scoop and transport the collected material to other places.

Further, as in asphalt pavement construction, a shovel is used for carrying and spreading the asphalt material manually, and a soil leveling tool is used for leveling work after the spreading. In this way, a separate tool is used in a series of operations.

[0005] As described above, in a series of operations for the same purpose, there is an inconvenience that tools must be prepared separately, with only slight differences in the contents of the operations. Therefore, the present invention proposes a new hand tool that can be handled with a single tool in related work.

As shown in Japanese Utility Model Publication No. Sho 62-50250 and Japanese Utility Model Publication No. Hei 7-43191, there has been proposed a tool for erecting a scooping part in a scoop. Since the connection mechanism between the scooping section and the gripping section is provided on the surface side of the scooping section, the scooping section having a sharpened tip is only used as a hoe by standing up, and can cope with the above-described various operations. Does not have a general-purpose structure.

[0007]

A hand tool such as a shovel according to the present invention is a hand tool in which a bar-shaped grip portion is mounted on the back of a scooping portion having a dish shape and at least a lower edge formed linearly. The present invention is characterized in that a grip portion is provided so as to be fixed by changing a mounting angle of the grip portion.

The above-mentioned realizing means is characterized in that an appropriate bending angle is provided at a root portion of the grip portion, and the grip portion is mounted so as to be rotatable and fixed in the axial direction. It is characterized in that the scooping part and the gripping part are connected via a connecting mechanism that can change the mounting angle to the scooping part, and further, with respect to the vertical direction of the gripping part, a part of the scooping part is It is characterized in that it is formed so as to be able to be bent in multiple stages on the horizontal axis, and that a holding mechanism for holding the bent state is additionally provided. Further, the scooping section is replaced with a fork body.

Therefore, when the scooping portion surface is substantially the same as the axial direction of the grip portion, the scooping portion can be used for scooping and transporting operations in the same manner as a normal shovel. If the whole or a part of it is in the standing state,
Operations such as scraping, leveling, and pushing can be performed.

[0010] Even when a fork body is employed, the fork body can be used as a fork for ordinary farm work or dairy farming if it is level with the grip portion, and can be used like a rake when it is in the upright state. It is.
