Embodiment 1

[0037] Such as Figure 1-4 As shown, the present invention provides a technical solution: an arc-shaped utility knife capable of actively triggering and reducing damage, including a knife shell 1, a storage track groove 2 is opened in the middle of the knife shell 1, and the right side of the knife shell 1 There is a tapered outlet 3, and the inside of the storage track groove 2 is slidably connected with a mobile slide 4. The inside of the mobile slide 4 is uniformly provided with a safety limiting groove 5, and a safety carrier 6 is arranged above the mobile slide 4. The safety carrier 6 The bottom surface is evenly and fixedly connected with a safety limiting rod 7, which is correspondingly engaged with the interior of the safety limiting groove 5. The two ends of the safety limiting groove 5 adopt a structure of a large circular groove and a narrow slideway in the middle, and the safety limiting rod 7 is connected to the safety limiting groove 5. The restricting groove 5 i...

Embodiment 2

[0042] Such as Figure 5 As shown, on the basis of Embodiment 1, the present invention provides a technical solution: a curved utility knife that can be actively triggered to reduce injuries. The cutting blade mechanism 14 includes an extended mounting plate 141, and the right side of the extended mounting plate 141 Fixedly connected with cutting blade 142, the right side of cutting blade 142 is fixedly connected with engraving and slipping cutter head 143, and cutting blade 142 can increase the resistance of cutting tool when stabbing personnel.

[0043] The left side of the extension mounting plate 141 is fixed between the mounting groove 11 and the auxiliary mounting plate 10 by the mounting nut 13 .

[0044] The cutting blade 142 adopts an arc-shaped wave structure, and the groove on the back of the bottom of the cutting blade 142 is fixedly connected with a blocking arc block 144, so as to realize the damping effect during sliding and avoid excessive force from cutting pe...

Embodiment 3

[0046] Such as Figure 6 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: an arc-shaped utility knife capable of actively triggering and reducing injuries. The support inserting rod 211 is fixedly connected to the inner side of the auxiliary finger-pressing board 20 , the top of the outer support inserting rod 211 runs through and is slidably connected with a transmission link 212 , and the end of the drive link 212 located outside the outer support insert rod 211 is rotatably connected with a clamp. The outer surface of the clamping wheel 213 is rollingly connected with the outer surface of the cutting blade mechanism 14 .

[0047] The inner bottom end of the transmission connecting rod 212 is fixedly connected with an inner splint 214 , and the bottom of the inner splint 214 is fixedly connected with the inside of the outer support inserting rod 211 through a squeeze spring 215 . Realize the fixation near the proc...

Abstract

The invention discloses an arc-shaped utility knife capable of actively triggering and reducing damage, which includes a knife shell, a storage track groove is provided at the middle position inside the knife shell, and a moving slide plate is slidably connected to the inside of the storage track groove, and the inside of the moving slide plate is uniform. A safety limiting groove is provided, and a safety carrier plate is arranged above the moving slide plate. The bottom surface of the safety carrier plate is evenly and fixedly connected with a safety limit bar, and the top of the safety carrier plate is fixedly connected with a transmission insert rod, and the outer side of the top of the drive insert rod is sleeved. An adjustment pressing plate is slidably connected, and an auxiliary mounting plate is fixedly connected to the right side of the transmission insert near the bottom, and a cutting blade mechanism is provided between the mounting groove and the auxiliary mounting plate. The present invention relates to the field of hardware technology. The arc-shaped utility knife capable of actively triggering and reducing damage can reduce the depth of stab wounds when the utility knife is used as a murder weapon, and improve the safety of the utility knife.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to an arc-shaped utility knife capable of actively triggering and reducing damage. Background technique [0002] A utility knife is a kind of knife used for art and handicrafts. It is mainly used to cut soft things. It is mostly composed of a plastic handle and a blade. It is a pull-out structure. There are also a few with metal handles, and the blades are mostly oblique, which can be broken along the line on the blade with a blunt blade, and a new blade emerges, which is convenient to use. [0003] As the Chinese invention publication number is: a kind of utility knife of CN106272568A, it has the advantage of easy operation. It includes a knife body, a locking structure, a regulator movably arranged in the knife body, and a blade connected to the regulator. The knife body includes a relatively movable lower knife seat, an upper knife seat, and an upper, An inclined-plane limit s...
