[0002] The integrally-formed patch inductor (hereinafter referred to as patch inductor) is a common electronic component. In order to facilitate mass production, the lead of the patch inductor is usually processed from a metal strip with a grid hole. The specific structure of the metal strip is that metal strips are arranged on both sides, and rib strips are arranged between the two metal strips to form a grid hole. A single patch inductor body is arranged on a single rib strip, and the two ends of the rib strip serve as the lead of the patch inductor. Therefore, the patch inductor will be arranged in a row during mass production.

[0003] During production, the lead needs to be bent, and the leads of the patch inductors are connected together by the metal strip, which is not convenient for bending operation. Therefore, the metal strip connected to the leads on both sides of the patch inductor needs to be cut off. In the prior art, a foot cutting device is used to cut off the metal strip. The foot cutting device mainly includes a plurality of parallel arranged troughs. Each trough is provided with a corresponding knife group above. The main structure of the knife group includes a pressing piece for pressing the patch inductor and a cutter fixed on both sides of the pressing piece by screws. A plurality of knife groups are connected with a driving cylinder through a connecting plate. The connecting plate is driven downward by the driving cylinder to drive the knife group to cut off the metal strip.

[0004] After a long time of cutting work, the cutter will be worn out, so it needs to be disassembled and replaced or maintained regularly. Since a plurality of knife groups are arranged in parallel, and the cutter is fixed on both sides of each knife group by screws, it is necessary to disassemble each knife group to disassemble the cutter on both sides of the knife group. During the installation of the cutter, the knife group needs to be repositioned to avoid affecting the cutting work. The whole disassembly and assembly process is complicated and time-consuming, which increases the downtime of the equipment and reduces the production efficiency. UTILITY MODEL CONTENTS
