Description

Farm tool device with replceable multi-purpose structure The present invention relates to a multi-purpose agricultural tool, and more specifically, to an agricultural tool with a multi-purpose replaceable structure that can be used for various agricultural tasks as well as other purposes in farmhouses, etc. Various manual agricultural tools, such as trowels, hoes, picks, and plows, are used not only by full-time farming households but also by ordinary households. These tools are designed to transmit the operator's force to the metal blade at the bottom through a handle that can be gripped. The more types of agricultural tools a household keeps, the more advantageous it is to use a structure where the handle and metal blade can be interchanged, in terms of economy and work efficiency. As relevant prior art documents, one may refer to Korean Registered Utility Model Publication No. 0463474 (Prior Art 1), Korean Published Patent Publication No. 2016-0100456 (Prior Art 2), and Korean Registered Patent Publication No. 1791198 (Prior Art 3). Prior art 1 expects that if the direction formed by the tool forming part and the handle is positioned in the direction of the handle length or perpendicular to it, it becomes a hoe, shovel, rake, and fork, thereby realizing four types with a single tool and expecting the effect of selecting the handle length and handle. Prior art document 2 comprises a fixing member having a blade fixing groove formed on the front and a handle fixing hole formed on the rear so that a fixing plate of the blade part is inserted and fixed; and a handle inserted and fixed into the handle fixing hole of the fixing member, and depending on the connection direction of the blade part, an agricultural fork or a rake can be selectively used, connection is easy, the handle is securely fastened, and the handle replacement is convenient. Prior art document 3 includes a handle portion having a male screw thread formed for a predetermined length; and a plurality of agricultural tool heads that are interchangeably coupled to the handle portion, each having a shape of one of various agricultural tools on one side and a female screw thread on the other side that corresponds to and screws with the male screw thread of the handle portion. Accordingly, it is expected that carrying and storing various agricultural tools will be convenient and that the cost of purchasing individual agricultural tools will be saved. However, according to the aforementioned prior art, it is limited to a maximum of four types of agricultural tools (blades), and it is not easy to adjust the posture other than the length variation, so improvement is required. FIG. 1 is a schematic diagram showing the overall structure of an agricultural tool according to the present invention. FIG. 2 is a schematic diagram showing the detachable member according to the present invention before and after operation. FIG. 3 is a schematic diagram showing a first embodiment of a controlling member according to the present invention. FIG. 4 is a schematic diagram showing a second embodiment of a controlling member according to the present invention. Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings. The present invention proposes an agricultural tool having a multi-purpose replaceable structure. It targets various agricultural tools such as trowels, hoes, picks, and plows needed by farm households or general households, but is not necessarily limited thereto. It also includes uses necessary for the daily life of farm households or general households, even if they are not directly related to various farming tasks. The metal blade (10) according to the present invention has a structure having a male part of the same shape for attachment and detachment at one end. Referring to FIG. 1, a plow is illustrated as a metal blade (10), but any agricultural implement is equipped with a male part of the same size. The male part formed at one end of the metal blade (10) can be closely engaged with the female part of the handle (20) described later. Since the handle (20) is used for various purposes, a concealed female part is preferred to protect it from impact. Of course, this does not exclude a configuration in which the metal blade (10) is the female part and the handle (20) is the male part. According to the detailed configuration of the present invention, the male portion of the metal blade (10) is characterized by concentrically combining an outer band (11) and an inner band (13) to form a step. Referring to FIG. 2, the outer band (11), inner band (13), and locking groove (15) constituting the male part of the metal blade (10) are shown. When the outer band (11) and the inner band (13) are joined concentrically, a step can be formed. The outer band (11) and the inner band (13) are preferred to be in the shape of a square tube, but a circular tube shape is not excluded. The step formed by the male part of t
