The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model provides a technical scheme:

embodiment 1, a small paper cutter structure

As shown in fig. 1-4, the device comprises a housing 8, the housing 8 comprises a front housing 1 and a front housing 2, the front housing 1 is fixedly connected with the front housing 2, a hollow groove 3 is formed at the rear part of the front housing 1, a hook shaft 4 is arranged at the lower part of the hollow groove 3, the hook shaft 4 is connected with one end of a spring 5, the other end of the spring 5 is connected with a fixed shaft 6, one end of the fixed shaft 6 is connected with the lower part of a blade 7, namely, a through hole is formed on the blade 7, the fixed shaft 6 is inserted into the through hole, the blade 7 is respectively connected with a sliding groove a9 and a sliding groove B10 in a sliding manner, a sliding groove a9 is formed at the rear part of the front housing 1, a sliding groove B10 is formed at the front part of the right housing 8, the other end of the fixed shaft 6 sequentially penetrates through a sliding groove a9, the hollow groove 3 and a limiting channel 11 to be fixedly connected with a handle 13, the sliding groove a9 is communicated with the hollow groove 3, the height of a9 is smaller than the height of the hollow groove 3, the hollow groove 3 is communicated with the hollow groove 3, and the limiting channel 11 is arranged on the front housing 1, spacing passageway 11 and fixed axle 6 sliding connection limit the distance that fixed axle 6 can move, and spacing passageway 11 communicates with each other and standing groove 12 is anterior indent structure of procapsid 1, and standing groove 12 contacts with handle 13.

The width and the length of the sliding groove A9 and the sliding groove B10 are the same, so that the sliding of the blade 7 in the sliding groove A9 and the sliding groove B10 can be facilitated; the width of the sliding chute A9 is larger than that of the empty groove 3, so that the blade 7 on the sliding chute A9 and the spring 5 in the empty groove 3 are not influenced mutually.

The handle 13 is provided with a plurality of protrusions 14, and the protrusions 14 are beneficial to increasing the friction force between the fingers so as to be convenient for pushing the handle 13.

The shell 8 is of a water drop type structure, accords with a human body mechanical structure, and is convenient to hold.

The working principle is as follows: when the paper cutter is needed, the paper cutter is manually applied to the protrusion 14 of the handle 13 and pushes the push handle upwards, the handle 13 slides in the placing groove 12, meanwhile, the fixing shaft 6 is also in sliding connection with the limiting channel 11, the spring 5 is subjected to stretching force and stretches and deforms in the empty groove 3, the blade 7 is pushed to move upwards in the sliding groove A9 and the sliding groove B10, the upper portion of the blade 7 is pushed out of the shell 8, and therefore paper can be cut by the blade 7, and the paper cutter is convenient to use. When not in use, the force applied to handle 13 is directly released, and spring 5 returns to its original state due to the absence of the tensile force applied to spring 5, facilitating downward movement of blade 7 within slide channel a9 and slide channel B10, without blade 7 being pushed out of front housing 1 and front housing 2, thereby eliminating the need to manually retract blade 7.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
