## Abstract

A position restriction structure of scissors includes a main body, a second body, a driving handle, a connecting piece, a restricting piece and a plurality of hinged units, wherein a main hinge hole and a second hinge hole provided for the second body and the driving handle are through and passing through a center portion of the main body, and the second body and the driving handle have a gearing teeth portion and a activating teeth portion engaged with each other. The restricting piece attaches to one side of the second body and driving handle and the hinge unit passes therethrough. The restricting piece clamps the second body and the driving handle through a screw and screw nut of the hinge unit to restrict axial position of the gearing teeth portion and activating teeth portion to prevent the second body from shear forces and to improve durability of the product.

## Claims

### Claim 1

A position restriction structure of scissors, comprising a main body, a second body, a driving handle, a connecting piece, a restricting piece and a plurality of hinged units,
wherein a main hinge hole is through and passing through a center portion of the main body, and a second hinge hole is through from one side of the main hinge hole, and a tool portion is extended downward from the other side of the main hinge hole;
the second body has a through rotating hole, and a second tool portion is extended from one side of the rotating hole, wherein an extended section is extended from one side of the rotating hole, and the extended section is bended to form a gearing teeth portion that has a through hole outside, and the rotating hole, extended section, and gearing teeth portion define a receiving space;
the driving handle has a conjugating portion that is located at the receiving space of the second body, and a conjugating hole and an activating teeth portion are formed corresponding to the rotating hole and the gearing teeth portion, respectively, and a second through hole is formed near the gearing teeth portion; and
the restricting piece has a third through hole on one side, and a sliding trough is formed on one side of the third through hole,
wherein the rotating hole of the second body and the conjugating hole of the driving handle are aligned with the main hinge hole and second hinge hole of the main body, the activating teeth portion of the driving handle engage with the gearing teeth portion of the second body, the restricting piece attaches to one side of the second body and driving handle, the third through hole and the sliding trough align with the second through hole of the second body and driving handle, and the hinge unit passes therethrough.

### Claim 2 (depends on 1)

The position restriction structure of scissors of claim 1, wherein the main body extends downward through the main hinge hole to form a handle, the conjugating portion of the driving handle is disposed in the receiving space of the second body, the fan-shaped activating teeth portion is formed corresponding to the gearing teeth portion, and extends downward to form a second handle.

### Claim 3 (depends on 2)

The position restriction structure of scissors of claim 2, wherein the tool portion of the main body and the second tool portion of the second body are of the shape of straight blade to form a cutting status.

### Claim 4 (depends on 1)

The position restriction structure of scissors of claim 1, wherein the tool portion of the main body and the second tool portion of the second body represent a blade and an anvil.
