Description

Cutter saddle of practice knife

Technical field

The utility model relates to a kind of Cutter saddle of practice knife, belongs to the hardware ﹠ tools technical field.

Background technology

Two kinds of structures of the general branch of normally used replaceable blade utility knife, a kind of structure is made up of blade, handle of a knife two parts, and blade directly is screwed in the middle of two handles, owing to do not have movable carriage, outside the cutting edge of blade always is exposed to, very dangerous; Another kind of structure is made up of blade, handle and movable carriage three parts, movable carriage and blade also are to be screwed in the middle of two handle of a knifes, different is in the middle of two handle of a knifes a slit to be arranged, movable carriage can drive blade and slide in slit, but makes the blade retraction and stretch out, and can reduce dangerous generation during blade retraction handle of a knife, but because the existence of glade plane space in the slit, blade can not be completely fixed, can become flexible, inconvenience works together.More than two kinds of structures also all have two kinds of same problems, the one, handle of a knife is oversize, is inconvenient to carry; The 2nd, just can carry out blade exchange after often needing to decompose two handle of a knifes, very inconvenient.

Summary of the invention

It is fixing reliable that the purpose of this utility model provides a kind of simple in structure, blade, can change the Cutter saddle of practice knife of blade very convenient, fastly.It can be connected with hinge with handle of a knife, can reduce the length of replaceable blade utility knife after folding up, and be easy to carry, and the cutting edge of blade also can be hidden in the handle of a knife after folding up, and reaches purpose of safety.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: it comprises knife rest main body and the cover plate with branch body structure, be provided with the blade detent that is complementary with blade between cover plate and the knife rest main body, and be connected through the hinge between cover plate and the knife rest main body.

The utility model also is provided with the U-shape lock button, is connected through the hinge between it and the knife rest main body.

Blade detent described in the utility model can be located on the knife rest main body, also can be located on the cover plate.

The inboard of U-shape lock button described in the utility model is provided with a boss, is provided with an elongated slot in the outside of cover plate, and boss and elongated slot make and constitute a mutual interlocking gear between U-shape lock button and the cover plate.

The utility model can be changed blade very convenient, fastly under the situation of not using any other instrument.

The specific embodiment

Embodiment 1:

Referring to Fig. 1, Fig. 3, Fig. 4, Cutter saddle of practice knife comprises that mainly knife rest main body 2, cover plate 3 and U-shape lock buckle 4 three parts.Knife rest main body 2 is the branch body structure with cover plate 3, and knife rest main body 2 is provided with blade detent 7 and positioning boss A, the B that is complementary with blade 1; Cover plate 3 and U-shape lock are buckled the 4 upper and lower both sides that are connected blade detent 7 edges respectively with

bearing pin

5,6, make hinge with knife rest main body 2 respectively and are connected; Cover plate 3 is provided with circular hole 8, is rotated so that pull cover plate 3 with hand; Equally, U-shape lock button 4 is provided with and pulls out sheet 9, can be convenient to pull U-shape lock button 4 with hand and be rotated.

In addition, in the outside of cover plate 3, be provided with an elongated slot 10, in the inboard of U-shape lock button 4, be provided with a boss 11, elongated slot 10 and boss 11 constitute a mutual interlocking gear when overlapping the position, make cover plate 3 and U-shape lock buckle 4 interlockings.

Small sircle hole 12 on the knife rest main body 2 and breach 13 are in order Cutter saddle of practice knife to be connected with handle of a knife and to fix, the convenient use.

The utility model is very convenient, fast when changing blade 1.When needing to change blade 1, only with hand is stirred U-shape lock button 4 and is upwards rotated around bearing pin 6, boss 11 on U-shape lock button 4 inboards is separated with elongated slot 10 on cover plate 3 outsides, then, pulling cover plate 3 with hand rotates around bearing pin 5, blade 1 is exposed fully, so just blade 1 can be taken out in blade detent 7.Otherwise, when blade 1 is installed, only need positioning boss A, B in breach a, b on the blade 1 aligning blade groove 7, put it in the blade detent 7, rotating plate 3 upwards then, it is downward to rotate U-shape lock button 4, and elongated slot 10 is overlapped with boss 11 positions, and formation cover plate 3 and U-shape lock are buckled 4 interlocking.So just finished the installation of blade 1.

Embodiment 2:

Referring to Fig. 2, in this embodiment, Cutter saddle of practice knife comprises that main body 2 and cover plate 3 and U-shape lock buckle 4, on knife rest main body 2 or cover plate 3, be provided with the blade detent 15 and/or the positioning boss 16 that are complementary with blade 17, the insert groove 18 on the blade 17 is complementary with positioning boss 16.All the other structures are identical with embodiment 1.

Embodiment 3:

Referring to Fig. 5: in this embodiment, Cutter saddle of practice knife comprises that knife rest main body 2 and cover plate 3 and U-shape lock buckle 4, and the connected mode that cover plate 3 and U-shape lock are buckled 4 interlocking structure and they and knife rest main body 2 is identical with embodiment 1.Different is that in the present embodiment, blade detent 7 and positioning boss A, B are not arranged on the knife rest main body 2, and are arranged on the cover plate 3.When needing to change blade 1, blade 1 will change over to together or produce with cover plate 3.

Embodiment 4:

Referring to Fig. 6: in this embodiment, Cutter saddle of practice knife comprises knife rest main body 2 and cover plate 3, and knife rest main body 2 is identical with embodiment 1 with the structure and the connected mode of cover plate 3.Different is, in the present embodiment, has replaced U-shape lock among the embodiment 1 by screw 14 and has buckled 4 snap action.This bothers slightly than embodiment 1 in use, needs to take off screw 14 with instrument earlier, just can carry out the replacing of blade 1 then.
