Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The present embodiment provides a utility knife, as shown in fig. 1-3, which includes a handle 100, a first blade holder 200 is disposed in a first end of the handle 100, a first blade 210 is disposed on the first blade holder 200, a push button 220 capable of sliding back and forth is disposed outside the handle 100, when the push button 220 is pushed forward, the first blade holder 200 moves forward and drives the first blade 210 to extend out of the handle 100, a return spring 230 is disposed between the first blade holder 200 and the handle 100, one end of the return spring 230 is fixed on the first blade holder 200, the other end of the return spring 230 is fixed on the handle 100, the return spring 230 provides a force for the first blade holder 200 to move backward, and the second blade holder 300 moves backward under the action of the return spring 230 to drive the first blade 210 to retract into the handle 100. The front-to-back orientation can be referred to in fig. 3, with the left side of fig. 3 being front and the right side being back.

The second end of the handle 100 is provided with a second blade 310, the second end of the handle 100 is provided with a through groove 320 with a downward opening, and the cutting edge of the second blade 310 is exposed at the through groove 320. When the bar-shaped objects or the sheet-shaped objects are embedded into the through grooves 320, and then the handle 100 is pulled or pressed, the second blade 310 can cut the cut objects, the cut objects are embedded into the through grooves 320 and are not easy to be separated from the through grooves 320, the cut objects can be cut even if the cut objects are operated by one hand, and the cutting edges of the second blade 310 are hidden in the through grooves 320, so that all parts of a human body are not easy to be embedded into the through grooves 320, users are not easy to be injured, and the use safety is ensured. In other alternative embodiments, the opening of the through slot 320 may be disposed upward.

The second blade 310 is a ceramic blade. The metal blade rusts easily and leads to the cutting edge to blunter, if be equipped with the multi-purpose sword in the car in order to cut off the safety belt in emergency, reserve multi-purpose sword probably does not use for a long time, inevitably forgets the state of checking the multi-purpose sword, if the cutting edge blunter probably leads to unable in time cutting off the safety belt. The ceramic knife can not rust, the knife edge can not be naturally dull, and the reliability that the multi-purpose knife is not suitable for a long time is ensured.

The second end of the handle 100 is fixed with a second blade holder 300, a second blade 310 is fixed on the second blade holder 300, and a through groove 320 is positioned on the second blade holder 300. Therefore, the second blade 310 can be conveniently disassembled, when the second blade 310 is disassembled, only the second tool holder 300 needs to be disassembled from the handle 100 firstly, the whole handle 100 does not need to be disassembled, and the positions of the first tool holder 200 and the first blade 210 cannot be involved in the disassembling of the second blade 310, so that the disassembling and the assembling are more convenient. In alternative embodiments, the second blade carrier 300 may be constructed integrally with the handle 100.

As shown in fig. 3, the outer wall of the through groove 320 is protruded to form a hook 340 relative to the inner wall of the through groove 320, so that the hook 340 hooks the cut object, and the cut object can slide into the through groove 320 along the hook 340 without aligning the cut object with the notch of the through groove 320, thereby facilitating the operation.

As shown in fig. 1, the second tool holder 300 has guide grooves 330 extending from the through groove 320 to the upper end of the second tool holder 300. Thus, when the sheet-like object is cut, the cut portion of the sheet-like object can move along the guide groove 330, thereby improving the smoothness and the flatness of the cut.

The second tool holder 300 includes a first holder 360 and a second holder 370, and the second blade 310 is clamped between the first holder 360 and the second holder 370, thus facilitating the removal and installation of the second blade 310. The second cartridge 300 includes a fixing portion 380 extending into the handle 100, and the fixing portion 380 is fixed to the handle 100 by screws. The handle 100 includes a first housing 110 and a second housing 120, the fixing portion 380 is clamped between the first housing 110 and the second housing 120, the first housing 110 has a limiting post, the second tool holder 300 has a limiting hole 350, and the limiting post penetrates the limiting hole 350. During installation, the position of the second tool holder 300 is limited by aligning the limiting hole 350 with the limiting column, so that the corresponding screw hole can be better aligned, and the screw fixing operation is facilitated.

As shown in fig. 2, the first frame body 360 has a limiting block 361, the second frame body 370 has a limiting groove 371, and the limiting block 361 is embedded into the limiting groove 371. The fixing portion 380 of the second tool holder 300 is clamped by the handle 100 and fixed by screws, the first holder body 360 and the second holder body 370 are not easy to have a gap at the position of the fixing portion 380, if the second tool holder 300 exposed out of the handle 100 is carried out, the first holder body 360 and the second holder body 370 are easy to have a dislocation or a gap, the stability of the second blade 310 is not beneficial to use, the position of the first holder body 360 and the position of the second holder body 370 exposed out of the handle 100 are respectively provided with the limiting block 361 and the limiting groove 371 to limit the two, the stability of the connection of the first holder body 360 and the second holder body 370 can be improved, and the reliability of the use of the second blade 310 is beneficial.
