Description
Technical field
The utility model relates to a kind of cutter, especially relates to a kind of evolute cutter that stores blade.
Background technology
At present, the cutter on the market is various in style, different, mostly is the attending classes articles for use that are used to cut paper.Because in actual use, fracture in blade head accident, the blade head length that perhaps exposes to the cutter shell need be regulated when adapting to different needs, blade just needs to pass before and after the phase tool setting shell, and when entering user mode, blade needs phase tool setting shell lock-bit could exert oneself to use, as the patent No. is that (notification number is the Chinese utility model patent of CN2576502 to ZL02249041.8: a kind of self-locking type cutter, this patent disclosure a kind of blade cutter of lock-bit automatically, this cutter includes 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, the surface of tool rest has a push button, the rear portion of tool rest has a groove, the top of groove is provided with a retaining mechanism, the two ends upside of retaining mechanism has a projection respectively, two protruding clips are on the ratchet of cutter shell, the two ends downside of retaining mechanism is respectively equipped with a brake block again, the centre of groove is provided with a guide groove, the two ends of groove are respectively equipped with a flexible block, the push button bottom is provided with an I-shaped guide rail, 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.This cutter props up brake block in the retaining mechanism by the I-shaped guide rail in the push button, projection in the retaining mechanism is stuck on the ratchet in the cutter shell and makes the locking of blade phase tool setting shell, when needing promotion blade phase tool setting shell to move, promote push button, push button overcomes the flexible block on the tool rest and removes the effect that is tight against to brake block in the retaining mechanism, thereby makes the projection in the retaining mechanism break away from the ratchet in the cutter shell and blade phase tool setting shell is moved freely.
But in this design, I-shaped guide rail in the push button is to rely on the flexible block on the tool rest and limit the position of its relative retaining mechanism and make it be against a side of brake block in the retaining mechanism, thereby, in this design, flexible block on the tool rest, brake block three's size in I-shaped guide rail in the push button and the retaining mechanism, position and mutual active force cooperate all need very accurately, there is deviation will make the ratchet of the projection disengaging cutter shell in the retaining mechanism slightly, also be, the lock-bit of blade phase tool setting shell was lost efficacy, this has increased the difficulty that the cutter actual production is made first, second in the frequent passing process of blade, flexible block follows the string easily and causes automatically locking blade position malfunctioning, makes the cutter can't operate as normal; Simultaneously, in this design, retaining mechanism is because of the frequent tool rest activity relatively of needs, it is provided with the comparison difficulty on tool rest, and flexible block also needs relative tool rest activity, its setting on tool rest is difficult to also realize that these all are unfavorable for actual production enforcement, specifically how to be arranged in this patent documentation all not mentioned; Moreover the projection in the retaining mechanism needs the ratchet activity of frequent phase tool setting shell, and common cutter generally all adopts engineering plastics to make except blade.
