[0004] This utility model provides a multifunctional electrician's knife, including a handle and a blade; the handle includes a first grip portion and a second grip portion that are slidably connected; the blade is located between the first grip portion and the second grip portion and is fixedly connected to the first grip portion; along the cutting direction of the blade, the first grip portion and the second grip portion have a first position close to each other and a second position far apart from each other; when the first grip portion and the second grip portion are in the first position, the cutting edge of the blade abuts against the second grip portion and is in a working state; when the first grip portion and the second grip portion are in the second position, the cutting edge of the blade is separated from the second grip portion and is in a non-working state.

[0005] Beneficial effects: By setting up a first grip and a second grip, with the blade positioned between the first and second grips, effective protection of the blade is achieved, ensuring that the blade edge is not exposed. This greatly reduces the safety risk caused by accidental contact. Even in environments with limited visibility or narrow operating spaces, accidental injury to the operator from the blade can be avoided. Furthermore, since the blade is fixedly connected to the first grip, the relative movement between the first and second grips allows the blade to move closer to and further away from the second grip, thereby enabling the blade to switch from a non-working state to a working state and back to a non-working state. This not only improves safety but also enhances ease of operation.

[0006] In one optional embodiment, a sliding locking component is further included, the sliding locking component comprising a first locking portion and a second locking portion; the first locking portion is fixedly connected to the first grip portion; the second locking portion is fixedly connected to the second grip portion and slidably connected to the first locking portion, having a locking position locked to the first locking portion and a disengaged position unlocked from the first locking portion; wherein, when the first grip portion and the second grip portion are in the first position, the second locking portion is in the locking position; when the first grip portion and the second grip portion are in the second position, the second locking portion is in the disengaged position.

[0007] Beneficial effects: When the first and second gripping parts are in a specific first position, they are in a locking position, thus fixing the blade position. This ensures that the blade remains stable during the stripping operation and will not slip or deviate from its predetermined position due to accidental movement. When the first and second gripping parts are moved to a second position, the second locking part is in a disengaged position, allowing the blade to separate from the second gripping part, facilitating the removal of the stripped cable. Through the positional changes of the first and second gripping parts, and the locking and disengaging function of the linked second locking part, flexible control of the blade position is achieved, greatly improving the convenience and safety of the stripping operation.

[0008] In one optional embodiment, the first locking part is provided with a sliding hole, and the second locking part includes a first connecting post and a locking member; one end of the first connecting post is fixed to the second gripping part, and the other end is slidably disposed in the sliding hole; the locking member protrudes from the outer periphery of the first connecting post; when the second locking part is in the locking position, the locking member is located in the sliding hole and engages with the first locking part; when the second locking part is in the separating position, the locking member separates from the first locking part.

[0009] Beneficial effects: When the second locking part is in the locking position, the locking member is located in the sliding hole and forms a stable locking relationship with the first locking part, ensuring a tight connection between the first locking part and the second locking part; when the second locking part is in the separated position, the locking member will separate from the first locking part, thereby releasing the locking relationship between the two and realizing the separation between the first locking part and the second locking part.
