Further, first knife sleeve includes first supporter, the second supporter, goes up to compress tightly the subassembly and compress tightly the subassembly down, and first supporter, the second supporter, go up to compress tightly the subassembly and compress tightly the subassembly down and form the protection groove that is used for holding the blade, go up to compress tightly the subassembly and constitute by a plurality of first compressing tightly strips, compress tightly the subassembly down and constitute by a plurality of seconds compressing tightly strips, and a plurality of first compressing tightly strips and a plurality of second compress tightly the strip and all inwards cave in to the protection groove.

Further, the second knife pouch is including connecting gradually and coaxial cover body and card pipe, the cover body including with the sword groove of putting of blade, put sword groove and card pipe intercommunication, the lateral wall of card pipe is opened in the axial of card pipe has two U-shaped breachs, card pipe and retaining member joint.

Furthermore, a plurality of first compressing strips and a plurality of second compressing strips are arranged in a staggered mode.

Further, the two U-shaped notches are symmetrical about the axial direction of the clamping pipe.

Further, the standing groove comprises chucking chamber, middle chamber and the thing breach of getting that connects gradually, and the cross-section in chucking chamber is isosceles trapezoid, and first broach shell is rectangular.

By adopting the technical scheme, the beneficial effects of the utility model are that: even if one knife sleeve is lost in the using process, the other knife sleeve is used for protecting the blade; the first knife sleeve can be inserted into the placing groove and is not easy to lose; due to the arrangement of the placing groove, the knife sleeve is more firmly fixed in the placing groove and is not easy to fall off; due to the arrangement of the first knife pouch, the first knife pouch can be firmly fixed on the art knife after being used for a long time and is not easy to fall off.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 6.

An art knife which replaces a knife sleeve, is not easy to lose the knife sleeve and is not easy to loosen after the knife sleeve is used for a long time.

The utility model discloses a concrete implementation scheme: the knife comprises a knife bar 1, a locking part 2 and a blade 3 which are connected in sequence, wherein a first knife sleeve 4 and a second knife sleeve 5 which are matched with the blade 3 are arranged on the utility knife, a placing groove 6 is formed on the knife bar 1, the first knife sleeve 4 extends into the placing groove 6 and is clamped with the knife bar 1, and the second knife sleeve 5 is clamped with the locking part 2; when the utility knife is not used, the first knife pouch 4 is inserted into the placing groove 6, and the second knife pouch 5 is clamped with the locking part 2 and protects the blade 3, so that the blade 3 can be protected by the replaced knife pouch after the second knife pouch 5 is dropped and lost; when the first knife sleeve 4 is used by an art knife, the first knife sleeve 4 is also inserted into the placing groove 6, so that the first knife sleeve 4 is not easy to lose.

The first knife sleeve 4 comprises a first support body 7, a second support body 8, an upper pressing assembly 9 and a lower pressing assembly 10, the first support body 7, the second support body 8, the upper pressing assembly 9 and the lower pressing assembly 10 form a protection groove 11 for accommodating the blade 3, the upper pressing assembly 9 is composed of a plurality of first pressing strips 12, the lower pressing assembly 10 is composed of a plurality of second pressing strips 13, and the first pressing strips 12 and the second pressing strips 13 are recessed into the protection groove 11; when the first knife sleeve 4 is matched with the blade 3, the blade 3 is inserted into the protection groove 11, and the first pressing strips 12 and the second pressing strips 13 which are sunken into the protection groove 11 extrude the blade 3, so that the friction force between the first knife sleeve 4 and the blade 3 is increased, and the knife sleeve is not easy to fall off.

The second knife sleeve 5 comprises a sleeve body 14 and a clamping tube 15 which are sequentially connected and coaxial, the sleeve body 14 comprises a knife placing groove 16 connected with the blade 3, the knife placing groove 16 is communicated with the clamping tube 15, the side wall of the clamping tube is provided with two U-shaped notches 17 in the axial direction of the clamping tube, the two U-shaped notches 17 are symmetrical about the axial direction of the clamping tube, and the clamping tube is clamped with the locking piece 2; when second broach shell 5 protected blade 3, stretch into blade 3 and put into sword groove 16 for in the retaining member 2's of locking blade 3 one end inserted card pipe 15, retaining member 2 is interference fit with card pipe 15, retaining member 2 struts two U-shaped breach 17, thereby the card pipe has certain resilience ability, so with retaining member 2 tightly together with the card pipe is fixed, and after long-time the use, the second card pipe is still difficult not hard up with retaining member 2's cooperation.

A plurality of first compressing strips 12 and a plurality of second compressing strips 13 are arranged in a staggered mode, so that different positions on the blade 3 are extruded, the extrusion area of the blade 3 is increased, the acting force of the first compressing strips 12 and the acting force of the second compressing strips 13 are opposite, and the acting force acts on different positions of the blade 3, so that the extrusion on the blade 3 is firmer, the first blade sleeve 4 is not prone to falling off the blade 3, and the blade 3 is better protected.

The placing groove 6 is composed of a clamping cavity 18, a middle cavity 19 and a fetching gap 20 which are connected in sequence, the section of the clamping cavity is isosceles trapezoid, and the first knife sleeve 4 is rectangular; when the first clamping pipe extends into the placing groove 6, one end of the first knife sleeve 4 is inserted into the isosceles trapezoid-shaped clamping cavity 18, so that the friction force between the first knife sleeve 4 and the placing groove 6 is increased, and the first knife sleeve 4 is not easy to fall off or lose; when the first knife sleeve 4 is inserted into the placing groove 6, the other end of the first knife sleeve 4 extends into the middle cavity 19 and is placed in the fetching notch 20, so that when the second knife sleeve 5 is taken out, the fetching notch 20 pushes the first knife sleeve 4, the first knife sleeve 4 can be taken out, the first knife sleeve 4 is very convenient to use, and the first knife sleeve 4 is not easy to pull out due to external force touch, and the knife sleeve is not easy to lose.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
