The specific embodiment
Referring now to accompanying drawing preferred embodiment of the present utility model is described in detail.
With reference to shown in Figure 1, this figure is the overall structure schematic diagram according to the cutter 10 of detachable blade of the present utility model.This cutter 10 comprises blade 20, tool rest 30 and handle of a knife 40, and wherein the part of blade 20 is inserted in the tool rest 30, and tool rest 30 is connected with handle of a knife 40 by similar fasteners such as screw, rivets again.In addition, pin 32a is installed also on tool rest 30, this pin 32a can slippage up and down in pin-and-hole 32.Be a straight line place and also be provided with a rivet 36a with this pin 32a is approximate.
On according to tool rest 30 of the present utility model, also offer decoration hole 38, different shape such as the shape of this decoration hole 38 can ellipse, rectangle, heart.This decoration hole 38 not only can play decoration function, and can be observed the position of blade 20 in tool rest 30 by this decoration hole 38, installs judging whether.
In addition, with reference to shown in Figure 2, this figure is the vertical view according to the cutter 10 of detachable blade of the present utility model shown in Fig. 1.Can find out that from this figure the top of tool rest 30 offers a groove 50 ', clamping sheet 50 can be inserted in this groove 50 '.
The annexation of blade 20 and clamping sheet 50 has been shown among Fig. 3.Wherein this blade 20 is provided with two grooves 22,24, and the clamping sheet is provided with two groove 22,24 corresponding two projections 52,54 therewith.Obviously, the quantity of this corresponding groove and projection can be arbitrarily, and is not limited only to two.When blade 20 and clamping sheet 50 are an angle mutually, for example 90 degree or 135 degree etc., and after being inserted in the tool rest 30 respectively can be placed in blade 20 inside at tool rest 30 by cooperatively interacting of groove 22,24 and projection 52,54.Obviously, the corresponding arbitrary shapes such as semicircle, arch, triangle, rectangle that can be of shape of groove 22,24 on the above-mentioned blade 20 and the projection 52,54 on the clamping sheet 50.In addition, also be provided with rivet hole 36 ' and pin-and-hole 32 ' on this clamping sheet 50, rivet 36a shown in Fig. 1 and pin 32a can be connected respectively in this rivet hole 36 ' and the pin-and-hole 32 '.
With reference to shown in Figure 4, this figure is the structural representation according to the cutter 10 of detachable blade of the present utility model, wherein for the detailed syndeton of this cutter 10 is shown, the part towards the reader of tool rest 30 is cut open, with the detailed annexation of the blade 20 that exposes tool rest 30 inside and clamping sheet 50 etc.
As of the present utility model preferred, also can be provided with a rivet hole 36 on the tool rest 30, one rivet 36a passes this rivet hole 36 on the tool rest 30 and the rivet hole 36 ' on the clamping sheet 50, thereby clamping sheet 50 is fixed on the tool rest 30, locator card contact pin 50 so better, and can make clamping sheet 50 rotate within the specific limits with respect to tool rest 30 around this rivet 36a.
Disassembly process according to the blade 20 of cutter 10 of the present utility model is as follows: press pin 32a downwards, make it overcome the elastic force of spring 60 and move down into the bottom of pin-and-hole 32, at this moment, the other end of the clamping sheet 50 (opposite end of pin 32a, promptly, an end that does not connect pin 32a) will on rivet 36a, move, thereby make two projections 52,54 on the clamping sheet 50 also move on correspondingly and throw off two corresponding grooves 22,24 on the blade 20, therefore, blade 20 can be taken out from tool rest 30, to carry out sharpening or directly to change.
When blade 20 is installed, at first press pin 32a, insert blade 20, remove the downward application of force on the pin 32a then, at this moment since the elastic force of spring 60 and on move the end that is connected with pin 32a of clamping sheet 50, at this moment, the other end of clamping sheet 50 (not being connected with the end of pin 32a) is downward around rivet 36a, thereby makes two projections 52,54 on the clamping sheet 50 snap onto in the corresponding recesses 22,24 on the blade 20, thereby blade 20 is fixed to the inside of tool rest 30.
Understand easily, according to the structure of the cutter of detachable blade of the present utility model applicable on various types of cutters, as common family expenses cutter, carpet knife, mica under-cutter etc.
In sum, according to the cutter 10 of detachable blade of the present utility model detachable blade 20 not only, and the dismounting of blade 20 is very convenient, need not use aid, can carry out fast.In addition, simple in structure according to the cutter 10 of detachable blade of the present utility model, be convenient to processing, thereby greatly reduce the manufacturing cost of cutter 10.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
