Detailed Description

The invention is further explained below with reference to the drawings and the embodiments.

Example (b): as shown in figures 1 to 4, the utility model relates to a novel left and right hand universal art knife, which comprises a knife body 1, a rear plug 2 connected with the tail part of the knife body 1, a knife container 3 installed in the knife body 1, a blade 4 installed in the knife container 3, a push key 6 connected with the knife container 3 in a sliding way is also installed on the knife body 1, a bottom key 5 connected with the push key 6 and buckled with the blade 4 is installed in the knife container 3, a positioning column 8 connected with the blade 4 is also fixed on the bottom key 5, a spring plate 7 connected with the knife container 3 is also installed on the bottom surface of the bottom key 5, a lug is connected on the bottom surface of the push key 6, a V-shaped groove is opened on the lug, a bulge connected with the push key 6 in a sliding way is installed on the surface of the bottom key 5, a trapezoidal groove connected with the spring plate 7 in a sliding way is opened on the bottom surface of the bottom key 5, an outward extending pressing sheet 9 is also fixed on the upper surface of one end of the bulge of the bottom key 5 close to the positioning column 8, the both sides of end key 5 are connected with support shell fragment 10 respectively, support shell fragment 10 one end and be close to end key 5 fixed connection of reference column 8 end, the other end along end key 5 side appearance extend and with end between the key 5 form the clearance, support shell fragment 10 still be connected with vertical arch on the upper surface of end key 5 one end far away from, shell fragment 7 passes end key 5 and pushes away the V type groove connection of key 6.

The knife container 3 is provided with a plurality of grooves matched with the elastic sheets 7, the elastic sheets 7 can move up and down along with the push keys 6 when being pressed, the elastic sheets 7 are positioned below the grooves of the knife container 3 and can freely move transversely when being pressed, and the elastic sheets 7 are higher than the grooves of the knife container 3 and are limited with the grooves when being released.

The elastic sheet 7 comprises a cuboid at the upper part and elastic sheet double wings symmetrically connected below, the elastic sheet double wings are in sliding connection with the bottom surface of the knife container 3, and the supporting elastic sheet 10 and the elastic sheet double wings are made of elastic materials.

The knife body 1 is also provided with a positioning groove, and the knife liner 3 is also provided with a positioning catch which is buckled and connected with the positioning groove.

The height of the projection of the push key 6 is larger than the height of the projection of the bottom key 5.

The working principle and the using steps are as follows: when the push button is installed, the elastic sheet 7 is installed in the bottom key 5, the push key 6 is installed in the groove in the middle of the bottom key 5, so that the push key 6 can be pushed back and forth from the left side and the right side, and at the moment, the lower end of the push key 6 is provided with the V-shaped groove, so that the upper end of the elastic sheet 7 can slide up and down under the action of the two wings of the elastic sheet by the left-right movement of the push key; the blade 4 is arranged on the bottom key 5, the blade hole penetrates through the blade positioning column 8, the blade pressing sheet 9 presses the blade 4 to prevent the blade 4 from falling off, the supporting elastic sheet 10 on one side props against the back of the blade 4, and the blade 4 enables the blade edge to be in a suspension state under the action of the supporting elastic sheet 10 on the other side and does not contact with the blade container 3 to protect the blade edge from being worn too fast; penetrating the knife container 3 into the knife body 1 from the tail part of the knife body 1, aligning the positioning blocking piece of the knife container 3 with the positioning groove in the knife body 1, pressing the positioning blocking piece of the knife container 3 into the positioning groove of the knife body 1, and fixing the knife body 1 and the knife container 3; the arranged spring plate 7, the bottom key 5 and the push key 6 are inserted into the knife container 3 from the tail part of the knife container 3, so that the spring plate 7 is preferably bounced up to the groove at the tail end of the knife container 3; and (5) mounting the rear plug 2 on the tail part of the knife body 1 and tightly clamping the rear plug, and finishing the mounting.

When the knife is used, the push key 6 is pushed forwards, the blade 4 is pushed out of the knife container 3 under the matching of the V-shaped groove at the bottom of the push key 6 and the bottom key 5, when the blade 4 needs to be retracted, the push key 6 is pushed backwards, the blade 4 is retracted into the knife container 3 under the matching of the V-shaped groove at the bottom of the push key 6 and the bottom key 5, when the blade 4 needs to be reversed to meet the requirement of a person who is accustomed to using the hand, in order to ensure that the art knife still has a rebound function, namely, in the process of pushing out the blade 4, the blade edge is always separated from the knife container 3 to protect the blade edge from being worn too fast, at the moment, the back plug 2 only needs to be detached, the blade edge of the blade 4 is changed in one direction, and the process can be simply realized through the matching of the blade 4 and the bottom key 5 with the knife container 3.

When the push key 6 is pushed forwards, the V-shaped groove bump on the top surface of the push key 6 presses the elastic sheet 7 to enable the elastic sheet 7 to move downwards, when the upper square part of the elastic sheet 7 is separated from the limit of the groove of the tool container 3, the push key 6 continues to move forwards along with the elastic sheet 7 to drive the bottom key 5 and the blade 4 to move together, so that the blade 4 extends out of the tool body 1, after the push key 6 is loosened, the V-shaped groove bump of the push key 6 is not stressed, the elastic potential energy stored by the two wings of the elastic sheet under stress is released, the elastic sheet is jacked upwards to enable the upper square part of the elastic sheet to return to the groove of the tool container 3, the elastic sheet is restored to the middle position of the V-shaped groove of the push key 6, and at the moment, the elastic sheet, the bottom key 5 and the blade 4 cannot transversely extend or retract under the limit; similarly, when the blade 4 is retracted, the V-shaped groove of the protruding block of the push key 6 can press the elastic sheet downwards to separate from the groove and remove the limit, so that the blade can move freely.

The above description is only for the purpose of illustrating the technical solutions of the present invention and not for limiting the same, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
