DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A detachable sickle, such as Figure 1-9 As shown: it includes a tool holder 1 and a tool head 2 matched therewith, an interlayer 3 is arranged on the inner side of the tool holder 1, and the opening of the interlayer 3 is on one side of the tool holder 1, and a second hole position 5 and a first hole position 4 are distributed up and down on the tool holder 1, a rotating shaft 6 is fixedly connected inside the first hole position 4, and a waist-shaped shaft 7 matching therewith is rotatably connected inside the second hole position 5, a locking plate 8 is movably connected to the outer side of the tool holder 1 through the waist-shaped shaft 7, the tool head 2 is movably inserted into the interlayer 3, a rotating groove 9 engaged with the rotating shaft 6 is arranged on the tool head 2, a waist hole 10 matched with the waist-shaped shaft 7 is also arranged on the tool head 2, and a notch connected to the waist hole 10 is arranged on the outer side of the tool head 2.

[0030] When assembling the tool holder 1 and the tool head 2, firstly, the locking plate 8 is turned upwards, at which time the waist-shaped shaft 7 is in a horizontal state, and the bottom end of the tool head 2 is inserted into the interlayer 3 of the tool holder 1, so that the rotating groove 9 on the tool head 2 is hooked on the rotating shaft 6, and then the tool head 2 is turned upwards with the rotating shaft 6 as the axis, so that the waist hole 10 is stuck on the waist-shaped shaft 7 through the notch position. When the waist-shaped shaft 7 is horizontal, the notch position just allows the horizontal waist-shaped shaft 7 to pass through, and the waist-shaped shaft 7 will also smoothly pass through the notch position and enter the waist hole 10, an inclined surface 11 is provided below the notch to provide a movable space for the engagement of the waist-shaped shaft 7, and then the locking plate 8 is flipped downward, and the locking plate 8 drives the waist-shaped shaft 7 to rotate. At this time, the waist-shaped shaft 7 is in an upright state. When the waist-shaped shaft 7 is upright, the notch position cannot allow the upright waist-shaped shaft 7 to pass through, so that the waist-shaped shaft 7 and the waist hole 10 will not be separated, completing the assembly. When disassembling, the opposite is true, and the end of the locking plate 8 away from the waist-shaped shaft 7 is in a tilted structure, which is convenient for flipping the locking plate 8 upward.

[0031] On the basis of the above structure, the utility model further provides a locking hole 12 on the locking plate 8, and a clamping column 13 cooperating with the locking hole 12 is provided on the outer side of the tool holder 1.
