It can be held in the previous technique. The utility knife consists of a grip and a blade. The blade protrudes forward and the knife is cut out for the user to cut the item. The second = grip = middle and the knife is retracted for storage. Please refer to the i = 2, the blade 3, the brake member 4 and the rotary member 5, ' = and the second cover member 12, and is provided at the inner near front end: 曰13 for inserting the blade 3 The knife seat 2, and the brake member 4 on the knife seat 2 protrudes from the outside of the handle 1 for manipulation, and a rotatable rotation fastener 5 is disposed at the near rear end of the first shell member 1 1 of the grip 1 And the second cover member 12 is corresponding to the position of the rotary member 5, and the through hole 121 having the abutting surface 12 is provided, and the rotary block 51 of the rotary member 5 is inserted outside, and the rotation is horizontal and the card is pressed against the ^ At 12 2, the first and second shell members 11 and 12 are assembled to each other and set to 1275458: shift 2 to !: kg, when used, 'hold the handle 1 and Λ 4 to π move the seat 2 And the blade 3 is linearly displaced forward, and the blade 3 is for cutting the article. When the blade 3 is passivated, the rotary fastener is rotated, and the block 51 is vertically separated from the card abutting surface 122 to release the jam. The knife: two shells Piece 1 1 and 1 2 separation In order to replace the front palpe on the knife seat 2, the blade of the utility knife is linearly displaced outside the grip, and the '1 〜成-sharp object' is susceptible when others accidentally touch the utility knife. The danger of the use of the blade i r is 'the user holds the utility knife to cut the second item, the tip of the blade and the article, the contact area is small, so that the blade is easy to sway during the process, and the operation cannot be facilitated to quasi-cancer In addition, when the 匕 can be ', the first and second shell parts of the handle must be disassembled and separated, and the yiyi '-i is not only inconvenient to replace the work. 'Because the knives are not positioned, and the shells are separated, they are detached. It must be re-split, all == blade material injury to the user, resulting in the safety of the tool change [invention] is to provide a rotary type utility knife, which is mainly for 2; (4) The knife mechanism has a --turning knife, a piece of film, and a 'swinging structure to control the rotation position of the turntable, and is used to rotate the belt to control the rotation of the turntable with the smashing mechanism of the knife-cutting mechanism. ; Γ 底面 底面 之 之 之 底面 底面 底面 底面 底面 底面 底面 底面 底面 底面Holder body, the cutting blade to the object, since the holding body immediately known and Μ = sharp objects' and avoid harm to others, the use of practical benefit to a liter of security. The purpose of the part is that the bottom surface of the holding body is provided with a guiding base material, and the base member is provided with a cutting hole for the cutting edge, and a guiding cut groove is provided for the user, so that the user can Auxiliary guided slip, and viewed by the guide slot _ I275458 for practical and effective cutting. Another object of the present invention is to have a tool change mechanism corresponding to the blade position on the grip body, which is to press the two blades under the blade with the control member, without disassembling the grip body, so as to facilitate the replacement of the blade and Improve the knife for the K. Another object of the present invention is to provide a sheet f on the turntable of the knife-removing mechanism, and to directly replace the full-position blade by the knife-out opening of the outside of the grip body, and to provide two-edge edge on the bottom surface of the grip body. The user can select the blade required for the structure selection, and directly control the other blade to be used for rapid use when a blade is passivated, thereby saving the tool change time and achieving the practical benefit of effective use convenience. [Embodiment] In order to make the present invention further understand the present invention, a preferred embodiment will be described in conjunction with the drawings, as follows: Referring to Figures 4 to 8, the grip body 6 of the present invention is substantially semi-circular and is composed of a knife holder 61 and a cover member 6 2, wherein the inner surface of the holder 61 is provided with a shaft hole. a slot 611 of the 612, and a retaining edge 613 having a second cutting edge 614 is disposed on the bottom surface of the slot 6 working, and the sealing 2 is also provided with a shaft hole 6 in the position of the shaft hole 612 of the corresponding blade holder 61. Oh, again. The inside of the holding body 6 is provided with a knife-out mechanism, which comprises a turntable 7 and a tilting structure. The turntable 7 is provided with two cutting slots 71, and has a rotating shaft 7 2 on the bottom surface 2, and the rotating shaft 7 2 is embedded. It is placed in the shaft hole β X 2 of the blade holder 6 ]_ and placed in the disk slot 611. The swaying structure is fastened to the top surface of the cover cover 6 2 and has a plurality of card slots 6 2 3 The slide rail 6 2 2 is provided with an elastically displaceable damper 8 which is composed of a push button 81, a magazine 8 2 and a bulge 8 3 , wherein the push button 8 1 The diameter of the rod body 8 1 ;! is slightly smaller than the width of the slide rail 62 2 , and penetrates into the slide rail 62 2 , and has a latching portion 812 at one end, the diameter of the latch portion 812 is slightly smaller than the card slot 1275458 6 2 3 Diameter '-set with 8 8 of the projectile 8 2 is set on the turntable 7 8 8 i fit assembly, and the spring 8 2 is embedded in the card ^ 6, the system is set in Holding the body concave - ancient one two? Near the respective cutting edges of the disk slot 6 1 1 , the position is 4: 4, and the blade slot 71 of the turntable 7 is provided with each of the slots 6 1 ' and corresponding to the cover 6 2 The displacement of the seat 6 1 can further be - and clamped, so that it can be elastically stretched and 1 ϊΐΐ Li ^ material 7 3 of the positioning block 7 4 is embedded in the blade and the sealing seedling Q 1 towel card positioning, and then the bolt Rotating the knife holder 6 1 to the other side ϋ β β The ejector member 8 of the ejector mechanism can drive the turntable 7 to guide the bottom surface to lock a guiding base member 20, the guide-boring hole? The position of each of the cutting edges 614 of the π 刀 刀 61 is provided with a double-blade guiding groove 2 〇 2 ′ and then -8 此 此 ; ; ; ; ; ; ; ; ; ; ; ; ; 于 于 于 于 于 于 于 于 于 于 6 6 6 6 6 The card ^ ^ 81 card 掣 812 off 8 1 1 is located in the 2 release card engine, so that the button 8 1 and the linkage ^ ^ 6 2 2 'in turn can push the push button 8 1 forward displacement, The seat=disk 7 rotates, so that the turntable 7 is on the face 3, and the limit position is: the upward push position is set, and the click portion 8 1 2 is embedded in the corresponding card slot 6 2 3, thereby turning the turntable 7 And blade phase: ^75458 for cutting items. As shown in the figure of Sjn13, when cutting the article, the user can further guide the base member 2 Q and then the end surface is placed on the object. 6, the blade is used to guide the grip body 6 to slide, so that the grip is held. Body stability, will not arbitrarily shake when the singer, t do not piece, and increase the level of operation, to achieve easy: 碹 f: use the guide cut slot 2 0 2 to view the cutting situation, the operation and the use of accurate cutting objects benefit. As shown in Fig. 1, when the side blade 1Q is purified, the user knife L n rf1 is displaced backward, and the turntable 7 is reversed _, so that the other side = two should be, 614 is out, and = _ Bp money knife time 'and then improve the convenience of the system.
