Abstract

The utility model provides a snap-off knife with improved structure, mainly comprising an outer case, a knife box, a slideway, a blade pushing sliding block, a fixed turn button and a rear end cover. Through the knife slideway of the utility model, a plurality of equidistant and sunk circular arcs and fixed turn buttons are arranged in the central of the rear side. The entering of the blade is smoother, and steadily fixing the blade is easier.

Description

Structure improved cutter

Technical field

The utility model relates to a kind of structure improved cutter, mainly comprises: shell, cutter casket slide rail, blade, blade advance slide block, fixed knob and rear end cap.

Background technology

General common existing cutter, in use, if blade is released long, and blade is made by elongated steel disc, often causes blade to be flexible bending, easily incised wound produce dangerous, and frangibility blade more; Moreover the blade of existing cutter is being released or during retracting blade, and is being had some setbacks, simultaneously positioning blade effectively firmly when fixed blade.

The utility model content

Be to provide a kind of structure improved cutter at the existing not enough the utility model purpose of above-mentioned existing technology.

At first, shown in Fig. 1,2, " structure improved cutter " 10 of the present utility model mainly comprises: shell 1, cutter casket slide rail 12, blade 2, blade advance slide block 3, fixed knob 4 and rear end cap 5, and wherein: shell 1 is the housing of elongate hollow, has a storage tank 11 in it; Cutter casket slide rail 12 is a sheet metal integrated punching bending forming, at the sunken circular arc 13 of the even a plurality of equidistant configurations that distribute of side central authorities; Blade 2 back are provided with a circular hole 21: this blade advances slide block 3 to protrude out in front end one side a positioning convex column 31 is set, and this blade advances slide block 3 central authorities horizontal running through to establish a screw 32, outside screw 32, the flexible shell fragment 33 of tilt planting, these flexible shell fragment 33 central authorities have hollow out 34; These fixed knob 4 one sides protrude out establishes a double-screw bolt 41, double-screw bolt 41 with fixed knob 4 one sides, place the hollow out 34 of flexible shell fragment 33, be screwed onto the screw 32 that blade advances slide block 3: this cutter casket slide rail 12 is worn the visitor who fastens at shell 1 and is put in the groove 11, the circular hole 21 of this blade 2 by the back is set on blade and advances slide block 3 positioning convex column 31 in front: after advancing slide block 3 combined on blade 2 and blade, place and be attached in the cutter casket slide rail 12, again rear end cap 5 engagings are socketed in shell 1 rear end, make it be combined into whole cutter 10 structures.

This shows, the utility model its in use, this blade stretches out random length, all can keep the structure improved cutter of suitable securement strength.

Fig. 1 represents structural representation of the present utility model.

Fig. 2 represents three-dimensional decomposition texture schematic diagram of the present utility model.

Symbol description: 10 art designings; 1 shell; 11 storage tanks; 12 cutter casket slide rails; 13 depression circular arcs; 2 blades; 21 circular holes; 3 blades advance slide block; 31 positioning convex column; 32 screws; 33 flexible shell fragments; 34 hollow outs; 4 fixed knobs; 41 double-screw bolts; 5 rear end caps.

The specific embodiment

The utility model such as above-mentioned each member are combined into whole cutter 10 structures, by changeing loose fixed knob 4, make the depression circular arc 13 of the double-screw bolt 41 disengaging cutter casket slide rails 12 of fixed knob 4 one sides, can be required according to the user, promote fixed knob 4 along cutter casket slide rail 12, blade 2 is released suitable length, again with the double-screw bolt 41 of fixed knob 4 one sides, it is corresponding on the depression circular arc 13 of cutter casket slide rail 12 to be spirally connected, and makes the advance and retreat of blade 2 smooth more just, reaches the fixing firm security of blade simultaneously.

The depression circular arc 13 of these cutter casket slide rail 12 1 sides also can be made as the circular hole that runs through, and can reach the structure of equivalence.

Claims

1. structure improved cutter of kind, it mainly comprises: shell, cutter casket slide rail, blade, blade advance slide block, fixed knob and rear end cap, and it is characterized in that: shell is the housing of elongate hollow, has a storage tank in it; Cutter casket slide rail is by sheet metal integrated punching bending forming, at the depression circular arc of the uniform a plurality of equidistant configurations of side central authorities; A circular hole is established in the blade back; This blade advances slide block, and one side protrudes out a positioning convex column is set in the front, and this blade advances slide block central authorities horizontal running through to establish a screw, outside screw, and the flexible shell fragment that tilts to plant, these flexible shell fragment central authorities have hollow out; This fixed knob one side protrudes out establishes a double-screw bolt, with the double-screw bolt of fixed knob one side, places the hollow out of flexible shell fragment, and is screwed onto the screw that blade advances slide block; This cutter casket slide rail is worn and is fastened in the storage tank of shell, and this blade is set on blade propelling slide block positioning convex column in front by the circular hole of back.
