Abstract
The utility model discloses a self-locking type art-designing cutter, which comprises a cutter blade and a cutter shell, wherein, a chute is arranged in the cutter shell, and one side of the chute forms relative continuous ratchets. A cutter base is arranged in the chute, and the surface of the cutter base is provided with a button and the rear part is provided with a through groove. The upper part of the through groove is provided with a locking mechanism, and the upper sides of both ends of the locking mechanism are respectively provided with a convex point. The two convex points are clamped on the ratchets of the cutter shell, and the lower sides of the both ends of the locking mechanism are respectively provided with a brake block. The middle part of the through groove is provided with a guide groove, and both ends of the through groove are respectively provided with an elastic limit stop. The lower part of the button is provided with an I-shaped guide rail which is inlaid in the guide groove of the cutter base, and both ends of the I-shaped guide rail are corresponding to the brake blocks of the lower sides of the both ends of the locking mechanism. Compared with the traditional art-designing cutter, the utility model has the advantages of simple structure, automatic locking, fast and convenient operation and high safety.
Description
Affiliated technical field
The utility model relates to a kind of cutter.
Background technology
Existing cutter, roughly be to be provided with a tool rest in its handle of a knife, the tool rest front end is provided with blade, and the tool rest surface is provided with a push button, promoting push button can make tool rest outer room in handle of a knife pass back and forth, the push button rear end is provided with a lock-button again, and under normal conditions, tool rest is in the state of freely releasing, during use, optionally tool rest is pushed out to the appropriate location,, whereby tool rest is locked on this position then with the lock-button post-tensioning.But should locking design, have weak point on operating characteristics and security performance, as previously mentioned, this tool rest must just can enter lock-out state with the lock-button post-tensioning in the opposite direction after release, and this staged operation mode is quick inadequately convenient; This kind cutter its tool rest before not using is to be in the state that can freely release again, can easily tool rest be released the security performance deficiency.
The utility model content
The purpose of this utility model is to provide a kind of facility, self-locking type cutter that security performance is good operated.
The self-locking type cutter that the utility model provides, comprise blade and cutter shell, has a chute in the cutter shell, one lateral margin of chute is formed with relative continuous ratchet, one tool rest is housed in the chute, and the surface of tool rest has a push button, and the front portion of tool rest has a projection, the rear end of blade is provided with a trepanning, and trepanning is enclosed within on the projection and blade is fixed on the tool rest; The rear portion of described tool rest has a groove, and the top of groove is provided with a retaining mechanism, and the two ends upside of retaining mechanism has a projection respectively, and two protruding clips are on the ratchet of cutter shell, and the two ends downside of retaining mechanism is respectively equipped with a brake block again; The centre of described groove is provided with a guide groove, and the two ends of groove are respectively equipped with a flexible block; Described push button bottom is provided with an I-shaped guide rail, and I-shaped guide rail is embedded in the guide groove of tool rest, and the two ends of the I-shaped guide rail brake block with retaining mechanism two ends downside respectively are corresponding.
The afterbody of cutter shell described in the utility model has an opening, and opening part is equipped with a cutter tail, and this structure can conveniently be installed tool rest and blade.
The utility model is except that blade, and remaining part is all made by engineering plastics, and cost is lower.
The utility model under normal conditions, tool rest utilizes the set protruding clip of retaining mechanism on its groove on the ratchet of cutter shell chute, the brake block of retaining mechanism two ends downside is withstood at the two ends of the I-shaped guide rail of push button bottom simultaneously, thereby make projection can't break away from ratchet tool rest can't outwards be passed, and constitute a lock-out state; During use, pass the push button of tool rest top forward, the I-shaped guide rail of push button bottom also moves forward, make the two ends of I-shaped guide rail break away from the brake block of retaining mechanism two ends downside on the tool rest groove, the projection that is stuck in simultaneously on the tool rest chute ratchet is become flexible and the disengaging ratchet downwards, thereby tool rest can be moved forward, can tool rest be released by push button this moment makes blade stretch out suitable length, discharge push button then, the flexible block that push button utilizes tool rest groove two ends to be provided with shrinks back I-shaped guide rail and withstands the brake block at retaining mechanism two ends, the projection at retaining mechanism two ends is replied clip between ratchet and return to lock-out state, and promptly tool rest is locked on this extension elongation.
Compare with traditional cutter, the utlity model has simple in structure, auto lock, facility swift to operate, characteristics safe in utilization.
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
