DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

An art designing knife with protection function as shown in fig. 1-7, which is composed of a knife rest 1, a holding grain 2, a connecting frame 3, a protective sleeve 4, a blade 5, a moving piece 6, a limit groove 7, a groove 8 and a protection device 9, and is characterized in that: the holding pattern 2 is arranged at the position below the tool rest 1; the connecting frame 3 is fixed above the tool rest 1; the protective sleeve 4 is fixed at the upper end of the connecting frame 3; the blade 5 is placed inside the engagement frame 3; the moving piece 6 is fixed above the end face of the connecting frame 3 and is of an integrated structure with the blade 5; the limiting groove 7 is arranged at the left end of the connecting frame 3; a groove 8 is formed at the joint of the right end of the connecting frame 3 and the tool rest 1; the protection device 9 is fixed at the lower left position of the engagement frame 3.

The protection device 9 comprises a protection tool 91, a support sleeve 92, a slide rail 93, a slide groove 94, a limit block 95, a knife groove 96, a spring 97, a first connecting block 98 and a second connecting block 99; the sliding grooves 94 are fixed at the upper end and the lower end of the protector 91 in parallel; the sliding rails 93 are fixed at the upper and lower ends of the support sleeve 92 in parallel; the limiting block 95 is fixed at the upper left position of the slide rail 93; the knife groove 96 is established between the protectors 91; the first joint block 98 is fixed at the right end of the protector 91; the second joint block 99 is fixed at the left end of the support sleeve 92; the spring 97 is fixed between the first engaging block 98 and the second engaging block 99.

Further, a rack 31 is arranged at the joint of the connecting frame 3 and the moving member 6; and the blade 5 and the moving member 6 are integrated to form a sliding connection with the rack 31 on the connecting frame 3.

Further, the slide rail 93 is slidably connected to the slide groove 94.

Further, in a normal state, the spring 97 is in a contracted state; and the protector 91 is at the maximum distance from the support sleeve 92.
