As shown in fig. 1 to 4, the utility knife includes a handle 100, a sheath 200 and a blade 300 capable of extending and retracting in the sheath 200, the handle 100 is provided with a compartment a for accommodating the sheath 200 and the blade 300, the handle 100 is fixedly sleeved outside the sheath 200, and the handle 100 is assembled at the rear section of the sheath 200. Preferably, the sheath 200 body is made of metal or plastic. The tail end of the knife handle 100 is provided with a knife tail cover 400.

The sheath 200 comprises a sheath body 200, the sheath body 200 comprises a bottom plate 01, an upper bent edge 021 and a lower bent edge 022 which are arranged on two sides of the bottom plate 01, and the bottom plate 01 and the two bent edges form a blade cavity K for accommodating the blade 300.

As shown in fig. 5 and 6, a positioning protrusion 3 is disposed on the inner side of the back plate 101 of the tool holder 100, a positioning hole 4 matched with the positioning protrusion 3 is disposed on the bottom plate 01 of the sheath body 200, and the positioning protrusion 3 is inserted into the positioning hole 4, so that the tool holder 100 and the sheath body 200 are fixed. The connecting mode reduces the use of fasteners, has simple structure, is convenient for assembling the knife handle 100 and the knife sheath body 200, and reduces the corresponding production cost.

As shown in fig. 4 and 6, a plurality of shift grooves 5 are distributed in an array on the lower bent edge 022 of the sheath body 200. The notch 5 is used to cooperate with the control member 500 at the rear end of the blade 300 to control the blade 300 to be located at different positions of the sheath body 200.

As shown in fig. 7, the insert 300 includes a cutter body 03, one side of the cutter body 03 is a blade portion 031 having a blade edge on the outer side, the other side of the cutter body 03 is a blade back 032, and a connecting hole 6 for connecting the control member 500 is provided at the tail of the cutter body 03. The cutter body 031 includes two cutter faces. Wherein, a plurality of breaking lines 7 distributed at intervals are distributed on at least one knife face to form a plurality of easy-breaking type blade units.

As shown in fig. 2 and 8, the control member 500 is connected to the connecting hole 6 of the blade 300 through the connecting portion 8, and the control member 500 controls the blade 300 to move with it in the blade cavity K of the sheath body 200.

As shown in fig. 1, 2, 4 and 6, a notch 04 is integrally formed on the bottom plate 01 and a lower bent covering edge 022 of the sheath body 200 corresponding to the blade portion 031 of the blade 300, the notch 04 is located at the front section of the sheath body 200, and is formed on the sheath body 200 at the front side of the holder 100, and the notch 04 extends to the side surface of the sheath body 200 to be open to the side surface of the art knife. The depth of the notch 04 exceeds the cutting edge of the cutting edge portion in the insert pocket K such that the cutting edge is exposed from the inner bottom edge 041 of the notch 04. It will be appreciated that the notches 04 serve to locate the string to be cut.

When a user wants to cut the rope, the user can hold the utility knife by hand, clamp the rope into the notch 04 and tighten the rope, wherein a part of the rope acts on the knife edge part 031 of the notch 04; the rope is now cut off from the point where it snaps into the notch 04 by applying a downward force. In addition, the user may also manipulate the control unit 500 to move the blade 300 after the string is caught in the notch 04, thereby cutting the string.
