Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To make it convenient to carry a mechanism such as a folding edge and a mechanism which can be assembled safely and easily with one blade without damaging the functions of a protruding chisel and a hoe. According to the present invention, a threaded connecting metal fitting 2 including a hexagon nut 3, a locking nut 3a (not shown), a spacer 4 and a connecting pin 5 is formed between a handle 1 of a tool and a blade 6. And fix it to the tip of handle 1 by welding or screwing,
On the other hand, the connecting pin 5 is rotatably assembled by inserting the connecting pin 5 into the hole of the base portion of the cutter 6 manufactured separately, and the blade tip is fixed according to the angle change, and the double function of the hoe and the chisel is performed by one.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to agricultural and forestry tools, and many tools of this kind are generally simple, and there are many kinds of tools to bring depending on the contents of work.

[0002]

[Prior art]

 A hoe is used to cultivate the land (ground) and dig a ditch, and a chisel is used to cut roots such as tree roots and bamboo roots and to dig holes. Therefore, to carry out these tasks, I used two tools, a hoe and a chisel, to use them properly.

[0003]

[Problems to be solved by the device]

 Forestry Especially when planting trees in the mountains, it is essential to plow the planting part and to cut roots such as roots of trees and bamboo roots and to excavate holes as described above with hoe and chisel. The chisel has a long handle, which is inconvenient to carry, and the blade of the hoe has a special feature that the blade tip is more prominent than the handle. In addition, the planting work in Yamano has a bad footing, and the places change one after another, so there is a great deal of labor involved in carrying tools, and there has been a demand for simple, lightweight, and small numbers.

[0004]

[Means for Solving the Problems]

 According to the present invention, the handle part and the blade part are manufactured separately, and a coupling fitting for unifying the separate body is fixed to the tip of the handle, and the tip of the coupling can be rotated by the cutting edge. In this way, the pin joint is used, and the cutting edge part is opened or fixed with a screw and a nut.

[0005]

[Embodiment of the invention]

 The blade tip is folded in the direction of the handle and stored during normal and transportation, so the blade tip does not come into direct contact with the human body, improving safety. Also, by bending the cutting edge 180 degrees, the overall length is shortened, making it easier to carry and carry.

[0006]

【Example】

 An embodiment will be described below with reference to FIG. The handle 1 of the protruding chisel is made of steel pipe or aluminum pipe to prevent slipping, and the threaded coupling fitting 2 is preferably threaded with stainless steel to be fixed to the handle 1. The hexagon nut 3 and the locking nut 3a (not shown) fix the blade portion 6. The spacer 4 is for adjustment with the root portion of the blade, and the connecting pin 5 is composed of a fulcrum that changes the angle of the blade edge 6. The angle of the cutting edge can be arbitrarily changed by moving the hexagon nut 3 and the locking nut 3a.

[0007]

[Effect of the invention]

 As mentioned above, the present invention has only one flee with a hoe, which can perform the dual work of a hoe and a chisel, so that it is possible to reduce the number of tools to bring, and at the same time to prevent danger of the cutting edge by occasional tatum, and to increase the total length. Because it can be shortened, it is convenient to carry.

FIG. 1 shows an embodiment of the present invention. In side view, A,
B and C are shape diagrams set for each function.

FIG. 2 is a side view and a front view E to E of a known chisel chisel D to D and a hoe that have been conventionally used.

Claims (1)

[Utility model registration claims] 1. A blade of a hoe or a protruding chisel and a handle portion are separately manufactured, and a tip portion of a screw-fitting coupling fitting for connecting the separated body to one body is a pin joint, and a blade tip portion is formed. It is configured so that it can be rotated, and the direction of the cutting edge can be folded and bent, and the angle of the cutting edge can be changed depending on the application, and it can be fixed with screws so that the cutting edge does not loosen, and different work can be done with one A chisel with a hoe.
