Technical field

The utility model relates to a kind of Cutter saddle of practice knife, especially a kind of pivoting Cutter saddle of practice knife, and it 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 is the replaceable blade utility knife that does not have knife rest, form by blade, handle of a knife two parts, owing to do not have movable carriage, outside the cutting edge of blade always is exposed to, very dangerous; Another kind of structure is the replaceable blade utility knife that has movable carriage, this kind movable carriage utilizes screw that blade is fixed 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 make the blade retraction and stretch out, but because the existence of glade plane space in the slit can not be completely fixed blade, can be loosening, inconvenience works together.

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 pivoting Cutter saddle of practice knife of blade very convenient, fastly.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: this kind pivoting Cutter saddle of practice knife, comprise knife rest main body and cover plate with branch body structure, the knife rest main body is provided with the blade that is complementary with blade and lays the place, its design feature is: be respectively arranged with axis hole on knife rest main body and the cover plate, cover plate can be laid in the place around the blade that axis hole axis nail turns in the knife rest main body.

Cover plate of the present utility model and/or knife rest main body can be sealed by a locking device, and described locking device can be thread lock mechanism or U type deduction structure.

Cover plate described in the utility model is provided with step, and the knife rest main body is provided with flanging, cooperates by flanging and step, makes cover plate and knife rest main body form a location mechanism between the two.

The utility model compared with prior art has following beneficial effect: 1, adopted a pivoting structure, cover plate all links to each other the project organization advantages of simple by same axle with the knife rest main body with handle in the replaceable blade utility knife.2, adopt the replaceable blade utility knife of the Cutter saddle of practice knife of this structure under the situation of not using any other aid, to change blade very convenient, fastly.3, can reduce the length of replaceable blade utility knife after adopting the replaceable blade utility knife of the Cutter saddle of practice knife of this structure to fold up, outward appearance is small and exquisite, light, be easy to carry, and the cutting edge of folding up the back blade also can hide in the handle of a knife, reaches purpose of safety.

The specific embodiment

Embodiment 1:

Referring to Fig. 1～Fig. 3, present embodiment mainly comprises knife rest main body 2, cover plate 3 two parts.Knife rest main body 2 is the branch body structure with cover plate 3, and knife rest main body 2 is provided with the blade that is complementary with blade 1 and lays place 4.On knife rest main body 2, also be provided with the axis hole 6 that can be connected, but also be provided with the axis hole 7 that is connected with handle 15 in the replaceable blade utility knife on the cover plate 3 with handle in the replaceable blade utility knife 15.Knife rest main body 2 and cover plate 3 utilize axis hole 6,7 to link to each other with handle 15 in the replaceable blade utility knife by axle nail 11, and knife rest main body 2 and cover plate 3 can rotate around circular hole 6,7 axis nail 11.Cover plate 3 can around the axle nail 11 that is connected with handle 15 turn to knife rest main body 2 in blade lay equitant position in the place 4.

The blade place of laying 4 can be detent or positioning boss structure, and the blade place of laying 4 is blade detent structure and positioning boss A, the B that is complementary with blade 1 in the present embodiment.

Also be provided with a location mechanism in the utility model, comprise flanging 12 and step 13.Interact by the step on flanging on the knife rest main body 2 12 and the cover plate 3 13,, make cover plate 3 and knife rest main body 2 locate mutually between the two, thereby the blade that makes 1 is more solid and reliable between knife rest main body 2 and cover plate 3 by the free degree of restriction cover plate 3.

On the knife rest main body, also be provided with locking device, described in the present embodiment locking device is a thread lock mechanism, mainly constitute by screwed hole 10 on the screwed hole on the knife rest main body 29, the cover plate 3 and screw 16, when screw 16 screws in screwed hole 10 and screwed hole 9 simultaneously, knife rest main body 2 and cover plate 3 are connected and fixed, thereby further clip blade 1.

The utility model is very convenient, fast when changing blade 1.When needing to change blade 1, only with hand unscrews screw 16, and screw 16 and screwed hole 9 are broken away from, rotating plate 3, make cover plate 3 and knife rest main body 2 not overlapping fully, the blade place of laying 4 that is complementary with blade 1 on the knife rest main body 2 is come out, just can take out blade 1 easily at this moment.Otherwise, when blade 1 is installed, only need that breach a, b on the blade 1 are aimed at blade and lay positioning boss A, the B that locates in 4, putting it into blade lays in the place 4, rotation cover 3 makes it overlapping fully with knife rest main body 2 then, screw in screw 16 in the screwed holes 9 again and screw, just can fix blade 1, also just finished the installation of blade 1.

Embodiment 2:

Referring to Fig. 4, Fig. 5 and Fig. 6, in this embodiment, embodiment comprises knife rest main body 2 and cover plate 3, and cover plate 3 is identical with embodiment 1 with the connected mode of knife rest main body 2.The locking device that different is in this example is a U type deduction structure, and it comprises that mainly a U type buckles 20.It is rubber-like parts that the U type buckles 20, is installed on the knife rest main body 2 by the axle in the hole on it 23.Buckle 20 inboard in the U type and be provided with boss 22, the arranged outside of cover plate 3 has shrinkage pool 21.Buckle 20 by swing U type, both are being positioned at when overlapping the position when shrinkage pool 21 and boss 22, buckle in the U type under self elastic reaction of 20, and boss 22 snaps in shrinkage pool 21 makes cover plate 3 and knife rest main body 2 form location and locking.

Column 17 is provided with on the cover board, can be used for promoting cover plate 3 rotations, and all the other structures are identical with embodiment 1.

Present embodiment is very convenient, fast equally when changing blade 1.When needing to change blade 1, only with hand is stirred U-shape lock button 20, and the boss 22 on U-shape lock button 20 inboards that make is separated with the shrinkage pool 21 on cover plate 3 outsides, then, with 3 rotations of hand propelled lid, blade 1 is exposed fully, so just blade 1 can be laid in 4 from blade and be taken out.Otherwise, when blade 1 is installed, only need that breach a, b on the blade 1 are aimed at blade and lay positioning boss A, the B that locates in 4, putting it into the blade blade lays in the place 4, then cover plate 3 is rotated to and knife rest main body 2 complete position overlapped, blade 1 is pushed down, it is downward to rotate U-shape lock button 20 again, shrinkage pool 20 is overlapped with boss 22 positions, and formation cover plate 3 and U-shape lock are buckled 4 interlocking.So just finished the installation of blade 1.

In addition; the utility model also has the exchange of other structure; be not limited to mode in the above-mentioned specific embodiment; such as; locking device has more than and is limited to above-mentioned screw locking mechanism or two kinds of mechanisms of U type deduction structure; can also other locking mechanism, this is that conspicuous conversion all should be to belong to protection domain of the present utility model for those of ordinary skill in the art.
