Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3: simple art knife with protective housing, including knife rest 4, blade 3 and knife shell 1, knife rest 4 is equipped with shell fragment 60, boss 45, square groove 41, sword groove 42 and chute 43, and blade 3 activity sets up in sword groove 42 and blade 3 stretches out chute 43, and blade 3 is fixed to be equipped with handle of a knife 2, and handle of a knife 2 is located square groove 41 department, and knife shell 1 cover is established outside knife rest 4 and knife shell 1 internal face is hugged closely with shell fragment 60.

The knife shell 1 is provided with a sleeve hole 12, the inner wall surface of the sleeve hole 12 is tightly attached to the elastic sheet 60, and the end surface of the boss 45 is positioned between two planes of the outer surface of the knife shell 1 and the inner wall surface of the sleeve hole 12. The end surface of the boss is higher than the inner wall surface of the sleeve hole, so that the sleeve hole gradually wraps the tool rest until the tool shell touches the boss, and the boss can limit the sleeving position of the tool shell; the end surface of the boss is lower than the outer surface of the cutter shell, so that the user cannot be obtrusive when touching the boss after gripping the cutter shell by hand; after the trepanning of the knife shell is sleeved in the knife rest, the knife shell can protect a user from being accidentally injured by the blade, and the elastic sheet can prop against the inner wall surface of the trepanning, so that the knife shell can be tightly matched with the knife rest, and the knife shell is not easy to separate from the knife rest when the blade is used.

The knife shell 1 is integrally formed by bending plates, the cross section of the knife shell is in a playground runway shape, and the knife shell 1 is provided with a crease 11. Firstly, cutting a whole roll of steel belt into a rectangular steel plate by using a plate shearing machine, and then bending the steel plate into a knife shell finished product by using stamping equipment, so that the knife shell has a crease, and the width of the crease is preferably 0.1-0.5 mm generally; if the crease is too small, the requirement on the processing precision is too high, and the production cost and the efficiency are influenced; if the crease is too large, the plate at the crease part is easy to deform, and the appearance of the knife shell is influenced.

The outer surface of the knife shell 1 is provided with an enamel layer. Enamel, also known as enamel, is a composite material in which an inorganic vitreous material is fused and solidified on a base metal and is firmly bonded with the metal; the enamel layer can endow the knife shell with beautiful appearance, and in addition, the enamel layer also has excellent performances of high hardness, high temperature resistance, wear resistance, insulating effect and the like.

The tool rest 4 comprises a left frame 5, a right frame 6 and a bending part 7 for connecting the left frame 5 and the right frame 6. The tool rest is made of a whole roll of steel belt, the steel belt is cut into rectangular steel blocks by a plate shearing machine, then the steel blocks are bent into tool rest finished products from the center line position by stamping equipment, the bending parts are just positioned at the center line position of the steel blocks, and the left frame and the right frame form a symmetrical structure by the center line.

The left frame 5 and the right frame 6 are both provided with a boss 45, a square groove 41 and a chute 43 structure, and the elastic sheet 60 is arranged in the middle of the right frame 6. Firstly, cutting a steel belt into rectangular steel blocks by using a plate shearing machine, then punching a boss, a square groove and a chute at the steel blocks by using punching equipment, and finally bending the steel blocks into a finished tool rest product; the shell fragment sets up in right side frame middle part, and the effect is better to the compressed action of tool holder shell, and the tool holder shell just is difficult for breaking away from the knife rest.

In the region away from the square groove 41 and the diagonal groove 43, the left frame 5 and the right frame 6 are attached to each other and provided with a welding table 44. And welding the left frame and the right frame together at the welding table by using a spot welding machine.

In the area close to the square groove 41 and the inclined groove 43, the left frame 5 and the right frame 6 are arranged at intervals so as to form a knife groove 42 for placing the blade 3, and the width of the knife groove 42 is smaller than the thickness of the knife handle 2. The tool shank is then not recessed into the tool pocket and the cutting insert is secured in the tool holder.

The right frame 6 is provided with an avoiding hole 63, the elastic sheet 60 comprises a connecting sheet 61 and a movable sheet 62, and the included angle between the connecting sheet 61 and the movable sheet 62 is 150-170 degrees. Therefore, the elastic sheet has certain deformation elasticity, after the knife shell is sleeved in the knife rest, the elastic sheet is extruded by the knife shell and sinks into the avoiding hole, at the moment, the junction of the connecting sheet and the movable sheet can prop against the inner wall of the knife shell to generate friction force, and the knife shell is not easy to separate from the knife rest.

The middle part of the blade 3 is provided with a hanging hole 32, and the two sides of the blade 3 are provided with limiting grooves 31. When the blade is used, the blade edge can become dull, and a new blade needs to be frequently replaced, so that more blades can be purchased, a plurality of new blades are stacked together, and after a rope or a round bar penetrates through the hanging hole, the plurality of new blades can be hung on a wall or other places, so that the blades are convenient to store; this kind of blade except using the utility model discloses in, also can use other cutter products, the spacing groove can make blade both sides by spacing locking, so the spacing groove makes the blade have better commonality.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
