Embodiment
Below in conjunction with Figure of description, the present invention will be further described.
A preferred embodiment of quick change fixing cutter of the present invention as shown in Fig. 3,5, including handle of a knife 01, blade 02, on handle of a knife 01 assembling be limited in expanded position（Referring to Fig. 1）With curling position（Referring to Fig. 2）Between the knife rest 03 that swings（Referring to Fig. 4）, the front portion of knife rest 03 sets blade putting position 31, and the rear portion of knife rest 03 sets blade storehouse 32, when knife rest is located at expanded position（Referring to Fig. 1）Blade putting position 31 is from the belly of handle of a knife produces handle of a knife, handle of a knife is produced in blade storehouse 32 from the back of handle of a knife, when knife rest is located at curling position（Referring to Fig. 2）Blade putting position, blade storehouse are collapsed to handle of a knife.
When being intended to more allowing blade replacement, only need rotating turret that blade putting position can be produced to handle of a knife, conveniently change the outfit blade, changes the outfit and afterwards receives knife rest to handle of a knife to rounding state；Therebetween, blade storehouse can produce or collapse to knife rest from knife rest in company with blade putting position, conveniently take spare blade.So that it is simple and convenient, improve efficiency.
Obvious, quick change fixing cutter of the above-mentioned figure as shown in Fig. 3,5, blade storehouse 32 therein can also be omitted, some spare blades now lacked in whole quick change fixing cutter, but blade putting position 31 still can easily produce in tool changing.
Specifically, knife rest 03 is assembled by pivot 11 and handle of a knife 01.The half section of axle docking illustrated in the first shank body, the second shank body that the pivot hereafter addressed by being respectively formed at forms.
In order to limit slewing area when producing handle of knife rest, a spacer pin 12 is set in handle of a knife 01, knife rest 03 is provided with spacing hole 33, and spacer pin 12, which is located at knife rest is limited between expanded position and curling position in spacing hole 33, to be swung.Specifically, the first shank body for hereafter being addressed by being respectively formed at of the spacer pin, half section of axle docking in the second shank body form, can also by hereafter address the shank body of fastening first, the fastener of the second shank body（Such as rivet, screw）Serve as.Obvious, although the spacer pin 12 of diagram is located at the right side of the pivot 11, the position of spacer pin 12, spacing hole 33 can be changed according to product design in the specific implementation.Alternatively, knife rest also can be kept out to be limited between expanded position and curling position by handle of a knife and be swung.
In order to fix blade, the back of blade 02 has locating notch 21, positioning bar 13 is provided with handle of a knife 01（Diagram is arranged in the second shank body 16）, when knife rest 03 is located at curling position（Referring to Fig. 2）Positioning bar 13 is located in locating notch 21.The structure from the belly of handle of a knife by blade putting position when producing handle of a knife（Referring to Fig. 1）, the locating notch of blade leaves positioning bar, is easy to extract blade forward.If however, being not limited to the above-mentioned mode for removing blade, positioning bar can also be set directly on knife rest, when installing blade, make locating notch correspond to positioning bar and blade is directly seated in blade putting position.
In order to avoid knife edge cuts knife rest causes blade to get stuck, assembled on knife rest 03 positioned at the position of blade putting position bottom（It is illustrated as being embedded in）One blade supporting plate 34, the blade of blade is located on the blade supporting plate when loading onto blade.So blade supporting plate is advisable using steel plate.
For the ease of rotating turret, the rear portion of knife rest 03 is provided with knife rest and turns round 35 positioned at dialling for handle of a knife ridge surface at curling position, and knife rest or gathering knife rest are conveniently produced by stirring to turn round.Obvious, dial torsion 35 and may be alternatively located at other positions, be such as located at the front portion of knife rest, and knife rest is located at handle of a knife abdominal surface at curling position.
In order to avoid blade drops, knife rest is provided with and corresponds to blade putting position, the magnet steel in blade storehouse respectively.
In order to which knife rest is maintained at into curling position, the elastic damping tabletting 14 of corresponding blade putting position is provided with handle of a knife 01（Referring to Fig. 2, one end of elastic damping tabletting 14 is securely fitted in the inner side of the first shank body 15）, when knife rest is gone into curling position（Referring to Fig. 2）, the pressure holding of elastic damping tabletting 14 passes to knife rest on blade 02 and by elastic force, and cutter setting frame produces damping and to be unlikely to knife rest unfettered and voluntarily produce handle of a knife.Elastic damping tabletting is arranged on into the position can avoid contact with knife rest on blade to contact and wear knife rest.
Specifically, handle of a knife 01 includes the first shank body 15, the second shank body 16 to be tightened together by fastener, knife rest 03 is between the first shank body 15 and the second shank body 16, first shank body or/and the second shank body are provided with the space that handle of a knife is produced for knife rest, the first shank body and the second shank body are made as into tabular and between space of the gap of self-assembling formation as described in, or the position setting breach of knife rest is correspondingly produced as described space in the first shank body or/and the second shank body.In addition, in order to increase curable grip, encapsulated 17 are fixed with handle of a knife；Rubber cushion 18 is further fixed in the front end at handle of a knife back to press for user.
