At the same time, the blade body can also be convenient for mountain climbing after being unfolded, meeting the needs of business operations.
[0015] 1. A protrusion is arranged on the second spring piece and at the upper end of the arc-shaped edge. This structure can apply a boosting rotational force to the first notch and the second notch in the main body of the chopping wood knife through the action of the protrusion and the elastic force of the second spring piece when the main body of the chopping wood knife rotates a certain angle during the unfolding process, so that the first notch and the second notch can automatically slide into the boss and the positioning block of the holder respectively, and have a semi-automatic unfolding function.
[0016] 2. A positioning block matching the first notch is arranged at the lower right end of the second spring piece. This structure can lock the first notch after the main body of the axe is unfolded to prevent the main body of the axe from loosening. At the same time, during the storage process of the main body of the axe, the positioning block can give the handle a rotational boost to realize the semi-automatic storage function.
[0017] 3. The design of the hook allows you to hang the folded axe around your waist, making it easier to carry.
[0018] 4. The design of the blade tip and the storage port makes it convenient to store the main body of the axe. The blade tip is stored in the storage port, which can prevent damage to the blade caused by accidental falls during climbing, and will not cause cuts to the body, thereby improving safety performance.
[0019] 5. The design of the blade locking piece allows the main body of the axe to be stored and unfolded, and can effectively lock the main body of the axe after folding and unfolding to prevent it from loosening, thus achieving normal field operations.
[0020] 6. Anti-slip patterns are arranged on the first handle and the second handle, and the first handle and the second handle are designed to be larger at the bottom and smaller at the top, so as to prevent the hand from slipping and loose grip when the axe is used in the field, which is conducive to the smooth progress of the operation.
[0021] 7. When the present invention is unfolded, the second notch will fall into the holder, and the positioning block will lock the first notch to prevent the main body of the axe from loosening; when the present invention is stored, the holder is pressed to elastically deform the first spring sheet to make the second notch come out, and the main body of the axe is rotated to make the blade fall into the storage opening, thereby realizing the folding of the axe.
