An opening (1) is arranged on one side of the blade sleeve, a blade is inserted into the opening (1), and an elastic clamping boss (2) is disposed at a position close to the opening (1) of the blade sleeve. Compared with the prior art, the blade sleeve has the advantages that the blade sleeve is convenient in use, is not easy to be loosened, is safe and firm and the like.
Description
Technical field
The utility model relates to daily life tools, relates in particular to the preposition blade cover of a kind of clamping device.
Background technology
Cutter is than one of indispensable apparatus in people's daily life, cutter has varied, as carpet knife, cutting knife or the like, jackknife is arranged, straight knife is also arranged, the straight knife Stability Analysis of Structures, save labour, make things convenient for than the jackknife use, but broach shell must be arranged, just can prevent because of placing or the improper personal injury that causes of taking, PVC cover packing cutter is adopted in the design of current many cutters, the ductility and the elasticity of this plastics are hard, indeformable, can only be a kind of the corresponding a kind of cutter of broach shell, and different big or small thickness blades will be provided with special broach shell, the cost of manufacture height.
Utility model patent ZL 200920142272.X discloses a kind of broach shell, comprises the broach shell body, and the madial wall of described broach shell body is provided with at least one guiding convex tendon, and this guiding convex tendon extends along the length direction of described broach shell body.A kind of cutter with broach shell, it comprises cutter and the broach shell that is set on the described cutter; The madial wall of described broach shell is provided with at least one guiding convex tendon, and this guiding convex tendon extends along the length direction of described broach shell body.When the user inserted cutter forward by the opening of broach shell, the guiding convex tendon can clamp the blade in the containing cavity, landing in blade is difficult for by broach shell when hanging.And, the guiding convex tendon has guide effect to the blade of plug in broach shell, make the easy plug of blade, especially on the broach shell that offers bigger sight vane during the plug blade, prevented that blade from inserting the personal injury incident that passes broach shell after askew and cause by sight vane, guaranteed consumer's personal safety.
Though this broach shell comparison safety, cutter that can only be corresponding fixing, and complex structure, cost height, narrow application range.
Utility model patent ZL200820176557.0 discloses the general broach shell of a kind of clamped-in style, comprise a broach shell body, the broach shell body is provided with leads cutter loading port and broach shell cavity thereof, broach shell cavity cross section is the U type, and the top of a side chamber wall of U type broach shell cavity is to the horizontal roof that protrudes from wall inboard, opposite side chamber that is provided with in the top at wall top, opposite side chamber.Roof aligns with the outside at wall top, described opposite side chamber; Be provided with between roof and the opposite side chamber wall and run through the broach shell cavity seam of taking a breath longitudinally.
Though this broach shell versatility is better, bulky, it is big to take up room, and carries inconvenience, and poor durability.
The utility model content
The purpose of this utility model, exactly for provide a kind of easy to use, be difficult for the preposition blade cover of clamping device that gets loose, be fastened securely.
In order to achieve the above object, the utility model has adopted following technical scheme: the blade cover that clamping device is preposition, one side of this blade cover offers the opening 1 that is used to insert blade, it is characterized in that, described blade cover is provided with elasticity near opening 1 place and clamps boss 2.
One side of described blade cover is provided with a side U type groove 6, and the opening of this U type groove is towards the front end of blade cover.
Form a compressing tablet that stretches out 3 between the U type groove of described blade cover side, this compressing tablet 3 is provided with elasticity clamping boss 2 near an end of opening 1.
Described clamping boss 2 is the inclined-plane in face of the one side of blade direction of insertion.
One side of described opening 1 is step-like, and opposite side is that plate is planar.
The front end of described blade cover is provided with can observe the sight vane 4 whether blade is inserted into the position.
The side up and down of described blade cover is provided with anti-slip tank 5.
The material of described blade cover is an elastomeric material.
Described elastomeric material comprises plastics or rubber.
Compared with prior art, the utility model blade cover is made up of two sizable trapezoidal faces, and the one side is provided with opening, and a side of opening is step-like, and opposite side is that plate is planar, and blade can paste the plate face and insert, and is stable convenient.
Side at the blade cover is provided with U type groove, form compressing tablet between the U type groove, front end at compressing tablet promptly is provided with an elasticity boss near opening part, and this elasticity boss is the inclined-plane in face of the one side of blade direction of insertion, and blade inserts along the inclined-plane that elasticity clamps boss, extruding elasticity clamps boss, it is made a concession in U type groove, in clamping blade, also have certain elasticity, even hang cutter, blade overlaps also difficult drop-off, has guaranteed consumer's personal safety.
