[Technical field to which the device belongs]

 The present invention relates to a work implement for gardening in which a farming tool main body is provided at the tip of a handle such as a rake, a hoe, a sickle, and a plow.

[0002]

[Problems to be solved by the device]

 In this type of gardening work tool, the worker has a handle, and the leading end of the handle is used to perform gardening work such as weed collection, composting, cultivation, and harvesting by the leading end of the handle. The handle is provided with a handle longer than that of the farm tool, and the farm tool body is integrally attached to the tip of the handle. Since such a gardening work tool has a long handle, it has a problem that it is bulky during transportation and storage, and also has a problem that the handle becomes an obstacle when cleaning the farming tool itself. Further, there are some cases in which the handle is colored in a different color from the farm tool body, but if the farm tool body and the handle are integrated, there is a problem that the coloring process during manufacturing becomes complicated.

In Japanese Utility Model Laid-Open No. Sho 63-160129, a handle is made exchangeable, and a notch is provided in a handle attaching portion of a tip fitting to vertically separate the handle attaching portion, and the handle is separated. A steel rake has been proposed in which washer portions are provided above and below the mounting portion, and bolts are provided in the washer portions so that the handle can be exchanged. However, with this rake, the bolt that is inserted into the bolt insertion hole can be used to tighten the split mounting part, so if the bolt is loose, the handle may come off, and the bolt may be tightened or loosened. Therefore, the attachment / detachment work was complicated.

Therefore, the present invention is to provide a gardening work tool in which the handle and the farm tool body can be easily attached and detached, which is easy to manufacture, can be provided at a low price, and is not bulky during transportation and storage. To aim.

[0005]

[Means for Solving the Problems] The invention of claim 1 is a gardening work tool in which a base end of a farming tool main body is detachably provided on a tip end of a handle, wherein the tip end of the handle and the base end of the farming tool base are respectively attached. Cylindrical parts are provided, one of these cylindrical parts is formed to be insertable into the other, and first and second cylindrical parts are formed with first holes, respectively, and inserted into these first holes. The gardening work tool is characterized in that the first projection is provided so as to be retractable by a spring in the one tubular portion, and one tubular portion is inserted into the other tubular portion, and When the holes of No. 1 are aligned, the first projections are projected into the first holes by the spring to fix the handle and the agricultural implement main body, and they do not come off during the work. Further, when the first protrusion is pushed in, the other tubular portion can be pulled out from the inside of the one tubular portion.

According to a second aspect of the present invention, the spring is a leaf spring in which one side piece and the other side piece are connected by a bent portion, and the first protrusion is provided on an outer surface of the one side piece. The agricultural work implement according to claim 1, characterized in that a leaf spring provided with a first protrusion is inserted from an open end of the one tubular portion, and the first protrusion is attached to the one tubular portion. By inserting into the first hole, the leaf spring can be attached to one of the tubular portions. Then, when the first protrusion is pushed in, the gap between the one side piece and the other side piece is narrowed, and when the pushing is released, the elasticity of the spring opens the gap between the one side piece and the other side piece, and the first hole The first protrusion projects.

According to a third aspect of the present invention, a second protrusion is provided on an outer surface of the other side piece of the leaf spring, and a second hole is formed in the one and the other cylindrical portions so as to face the first hole.

[Embodiment of the device]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 3 show a first embodiment of the present invention, in which a rake 1, which is a gardening work tool, has a handle 2 having a farm tool body 3 detachably attached to the tip thereof. A plurality of tooth rods 4 are provided at the tip of 3 at intervals in the left-right direction. The handle 2 is made of a pipe, and a tubular portion 5 having a circular cross section is provided at the tip of the handle 2, and a tubular portion 6 into which the tubular portion 5 can be inserted is provided at the base end of the farm tool body 3. The cylindrical portions 5 and 6 are provided with the first holes 7 and 8, respectively. The cylindrical portions 5 and 6 have open ends 5A and 6A, respectively.

The leaf spring 9 provided in the tubular portion 5 of the handle 2 is formed by connecting the one side piece 10 and the other side piece 11 by the bent portion 12, and the one side piece 10 and the other side piece 11 are connected to each other. Mounting holes 10A and 11A are respectively formed at the tips of the first projections 13 in this example, and the lower end of the outwardly projecting first projection 13 is fixed to the mounting hole 10A of the one side piece 10 by caulking. Are formed so that they can be inserted into the first holes 7 and 8. Further, the length dimension L of the leaf spring 9 is formed longer than the tip end distance H between the one side piece 10 and the other side piece 11, so that the distance H of the leaf spring 9 is narrowed against its elasticity. Then, the leaf spring 9 is inserted from the open end 5A of the tubular portion 5, and the first protrusion 13 is inserted and arranged in the first hole 8. Therefore, the length dimension of the leaf spring 9 is formed longer than the inner diameter D which is the inner dimension of the tubular portion 5, and the bending portion 12 is located on the open end 5A side of the tubular portion 5. In this state, the outer surfaces of the one side piece 10 and the other side piece 11 are in pressure contact with the inner surface of the tubular portion 5. Further, the pattern 2 is colored white by a coloring layer 14 such as painting, and the farming tool body 3 is colored black.

Next, the method of assembling the rake 1 will be described. The first protrusion 13 is pushed in against the elasticity of the leaf spring 9, and the one tubular portion 5 is inserted into the other tubular portion 6. Then, the first protrusion 13 is inserted into the first hole 7 of the one tubular portion 5, and the handle 2 and the farm tool body 3 are fixed. Further, by pushing the first protrusion 13, the other tubular portion 5 can be pulled out from the inside of the other tubular portion 6.
