Description

Art designing knife with locking function

Technical Field

The utility model belongs to the technical field of art designer's cutter and specifically relates to an art designer's sword with locking function is related to.

Background

The art knife is commonly called as a graver or a wallpaper knife, is a knife for art or handicraft, and is mainly used for cutting objects with soft texture, such as leather, hardboard, paper and the like.

The utility knife has the advantages that the styles and functions of the utility knife are very many, some utility knives are very small and are mainly used for fine handcrafting, some utility knives are wide and large, the knife edges are very sharp, and wood, plastic rods and the like used in the handcrafting can be easily cut off.

The utility knife usually only uses the knife point part when the utility knife is normally used, the cutting and carving decoration are the main functions of the utility knife, but the knife blade is very fragile, the knife blade which is too long can not be extended when in use, otherwise the knife blade can be broken when in use, and the hardness and durability of the knife blade are different due to the difference of the materials of the knife blade. When the cutter point of the cutter blade is found to be dull in the use process of the utility knife, people can break the cutter blade with the dull front end by using the vice, so that a new cutter point can be exposed and can be continuously used by people.

At present, a plurality of types of art designing knives appear on the market, wherein in the using process of a part of art designing knives, the knife blades are retracted due to excessive force applied by people, and the cutting of leather, hard paper boards and paper is not in place, so that the cutting quality is directly influenced; in view of the above problems, technicians in this company need to design a new art knife to solve the problems.

Disclosure of Invention

The utility model aims to solve the technical problem that an art designing sword with locking function is provided, can lock the blade through the safety bolt after closing up top rest, lower knife rest, prevent that the blade from producing under the too big condition hard and returning.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides an art knife with locking function, includes the knife rest and is located the blade of knife rest, the knife rest include top rest, lower tool rest, the top rest be provided with first locking device, the lower tool rest be provided with second locking device, first locking device and second locking device looks butt, top rest and lower tool rest sliding connection, top rest and lower tool rest pass through the safety bolt locking.

As a further improvement of the present invention, the first locking device is provided with a convex edge, the second locking device is provided with a groove, and the convex edge is connected with the groove. Through the clamping connection of the convex edge and the groove, the reliable connection between the upper tool rest and the lower tool rest can be ensured.

As a further improvement of the utility model, the convex edge is provided with a slope with inclination.

As a further improvement of the utility model, the groove is provided with a contact pin which is in butt joint with the slope. The slope is abutted against the contact pins, so that pressure towards the slope direction can be generated when the slope and the contact pins are contacted, and the upper tool rest and the lower tool rest can be tightly held to lock the blade.

As a further improvement of the utility model, the blade be provided with the elasticity screens piece that can promote its removal, the lower tool post be provided with the fender bit block that can restrict the elasticity screens piece and roll back. When people want to use the utility knife to cut leather or paper, the accessible elasticity screens piece pushes out the blade behind the knife rest and carries out cutting work, however when people exert oneself too big, keeps off the condition that the position piece just can restrict the elasticity screens piece and produce and roll back, guarantees to cut smoothly.

As a further improvement of the utility model, the elastic clamping piece be provided with spacing portion, spacing portion be connected with the fender position piece. The limiting parts are connected with the stop blocks in a matched mode, and when the stop blocks are multiple in number, the length of the blade extending out of the cutter frame can be adjusted.

As a further improvement, the lower knife rest is provided with a knife track for placing the blade, and the upper knife rest is provided with a pressing block capable of pressing the blade. The blade is placed in the tool path, the blade can be guaranteed to move according to the specified route of the tool path, the deviation or the blocking phenomenon cannot be generated, the pressing block is used for locking the blade, and the blade cannot move after being locked in the using process.

As a further improvement of the utility model, the lower tool rest be provided with screw thread portion, the safety bolt and screw thread portion threaded connection. The safety bolt can push the lower tool rest to move by rotating, so that the upper tool rest and the lower tool rest generate relative displacement, and finally, the upper tool rest and the lower tool rest are loosened and locked.

As a further improvement, the elastic clamping piece is provided with a driving lever, and the upper tool rest is provided with a guide groove matched with the driving lever. When people push the elastic clamping piece, the deflector rod can facilitate people to push the blade out of the knife rest, and the guide groove can guide the elastic clamping piece to move according to a specified route.

As a further improvement, the elastic clamping part is provided with a hanging part, the blade is provided with a perforation, and the hanging part is sleeved with the perforation. The hanging part facilitates the connection of the elastic clamping piece and the blade, and when the blade needs to be replaced, the operation is convenient.

The utility model has the advantages of can lock the blade after upper knife rest, lower knife rest are drawn together through the safety bolt, prevent that the blade from producing under the too big condition hard and returning. When the safety bolt does rotary motion, can make the lower tool rest produce the displacement for the upper tool rest, when lower tool rest and upper tool rest are in the relaxed state, the motion that the blade can advance or retreat is carried out, when lower tool rest and upper tool rest pass through the safety bolt locking, the blade is locked between upper tool rest and lower tool rest, guarantees that the blade can not produce the phenomenon of rolling back because of people exert oneself excessively in the use to make cutting work go on smoothly.
