Description
Technical field
The utility model relates to draw tool technical field.
Background technology
Cutter daily life, study or office time often use, and for drawing specialty Faculty and Students indispensable especially stationery, cutting a sheet of paper in painting process, scrape figure, change plan etc. all needs frequently to use cutter.Cutter is commonly called as icking tool or wallpaper cutter, is a kind of fine arts and the cutter doing artifacts, is mainly used to cut the softer material of quality, how being made up of plastic knife handle and blade two parts, be drawing and pulling type structure, blade mostly is angle, can fracture along the line of sheet body after being worn out, occur the new knife edge.And the cutter that existing market is sold uses and inconvenience, due to blade in use need constantly extrapolated, fracture, too much easily hand can be hindered once be released by blade, the holds of cutter holds the flat that position mostly is upper opening in addition, be inconvenient to exert oneself, and when painting, needing to hold for a long time handle of a knife force, hand therefore of long duration just easily produces sense of fatigue.
Utility model content
Technical problem to be solved in the utility model is to provide the drawing utility knife special of simple, the easy to use, safe practicality of a kind of structure, uses when being particularly suitable for drawing.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of drawing utility knife special, comprise blade, tool shank cartridges, split type broach shell and cutter cap, described blade one end is fixed in tool shank cartridges, and the other end is successively through broach shell, and described cutter cap is contained in blade end.
Preferably, described tool shank cartridges is the clamp connection structure of two-piece unit, comprise base and upper slip lid, the two sides that described base coordinates with upper slip lid are provided with chute, described upper slip lid both sides are provided with the boss coordinated with chute, described base upper surface is provided with the cylinder coordinated with blade fixing hole, and be provided with on rear side of described upper slip lid with after base clamping and make tool shank cartridges smooth outer surface excessive, described tool shank cartridges front end coordinates with broach shell.
Preferably, be provided with the via hole with blades fit in the middle part of described broach shell, described via hole side is provided with shell fragment, and it is consistent with blade direction of insertion that described shell fragment tilts end, and described shell fragment tilts end and is provided with straight pin, and described straight pin runs through broach shell sidewall.
Preferably, described straight pin is set with back-moving spring.
Preferably, described broach shell front end is arc convex surface, and rear end is circular arc concave surface, and before and after can making, adjacent broach shell cooperatively interacts.
Preferably, in the middle part of described broach shell, corresponding blade both sides are provided with and hold radian, and the outside corner angle of described tool shank cartridges, broach shell and cutter cap are arc transition.
The beneficial effect adopting technique scheme to produce is: utilize split type broach shell to be in use convenient for changing, only top broach shell need be removed after blade is with blunt fractureing and can expose the new knife edge, during use, blade is arranged on after in tool shank cartridges, again blade is inserted successively the via hole in broach shell, by blade fixation under shell fragment effect, back-moving spring on straight pin can make shell fragment keep elasticity, and the used time is not by cutter cap, safe and reliable in use procedure; Broach shell both sides hold the more convenient gripping of radian, the arc convex surface of broach shell front end exerts a force more convenient when operating, strengthen hand comfort.The utility model has the advantage of simple, the easy to use, safe practicality of structure, for drawing professional, have more practicality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
One drawing utility knife special as shown in figures 1 to 6, comprise blade 1, tool shank cartridges 2, split type broach shell 3 and cutter cap 4, described blade 1 one end is fixed in tool shank cartridges 2, and the other end is successively through broach shell 3, and described cutter cap 4 mounts cover at blade 1 end.Described tool shank cartridges 2 is the clamp connection structure of two-piece unit, comprise base 21 and upper slip lid 22, the two sides that described base 21 coordinates with upper slip lid 22 are provided with chute, described upper slip lid 22 both sides are provided with the boss coordinated with chute, described base 21 upper surface is provided with the cylinder 23 coordinated with blade 1 fixing hole, being provided with on rear side of described upper slip lid 22 with after base 21 clamping makes tool shank cartridges 2 smooth outer surface excessive, and described tool shank cartridges 2 front end coordinates with broach shell 3.
Be provided with the via hole 31 coordinated with blade 1 in the middle part of described broach shell 3, described via hole 31 side is provided with shell fragment 32, and it is consistent with blade 1 direction of insertion that described shell fragment 32 tilts end, and described shell fragment 32 tilts end and is provided with straight pin 33, and described straight pin 33 runs through broach shell 3 sidewall.In order to keep the elasticity of shell fragment 32, a back-moving spring 34 can be set with on straight pin 33.When in the via hole 31 that blade 1 inserts broach shell 3, shell fragment 32 will be pressed down, thus drive straight pin 33 to move down to expose broach shell 3 sidewall, under spring 34 acts on, can by blade 1 firm compression in via hole 31; When after extraction blade 1, shell fragment 32 resilience under the effect of back-moving spring 34, straight pin 33 bounces back.
Conveniently hold force, be connected successively by each joint broach shell 3 simultaneously, can be arc convex surface 5 by broach shell 3 Front-end Design, rear end be designed to circular arc concave surface 6, and before and after can making, adjacent broach shell 3 cooperatively interacts, and is designed blade 1 both sides corresponding in the middle part of broach shell 3 and holds radian 7; In order to prevent pressing against hand in use procedure, the outside corner angle of described tool shank cartridges 2, broach shell 3 and cutter cap 4 are arc transition.
In sum, it is simple that the utility model has structure, easy to use, safe and practical advantage, split type broach shell 3 is utilized in use to be convenient for changing, only top broach shell 3 need be removed after blade 1 is with blunt fractureing and can expose the new knife edge, first blade 1 is arranged on after in tool shank cartridges 2 during use, again blade 1 is inserted successively the via hole 31 in broach shell 3, by blade 1 fixation under shell fragment 32 acts on, straight pin 33 is given prominence to broach shell 3 outer wall and can be used safely, cutter cap 4 does not cover by the used time, back-moving spring 34 on straight pin 33 can make shell fragment 32 keep elasticity, safe and reliable in use procedure, broach shell 3 both sides hold the more convenient gripping of radian 7, the arc convex surface 5 of broach shell 3 front end exerts a force more convenient when operating, strengthen hand comfort.For the user of drawing specialty, while protection hand, also slow down hand fatigue sense, have more practicality.
