Description

Technical Field

[0002] Circuit boards are widely used in people's daily lives. They can be used to produce electronic watches, mobile phones, electrical appliances, etc. They can make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. In order to better apply circuit boards to the production of products of different sizes, circuit boards often need to be cut into different sizes.

[0003] The patent with publication number CN210633761U discloses that the second gear is driven to rotate through a toothed connection. The utility model can fix the two ends of the circuit board by setting a movable plate, a groove and a screw rod. The movable block on the screw rod moves back and forth to make the two ends of the circuit board relatively still, thereby reducing the error. By setting a spring, circuit boards of different widths can be selected.

[0004] However, when cutting the circuit board, since the position between the cutting machine and the circuit board is fixed, the cutting machine can only cut one fixed position on the circuit board, which cannot meet the user's purpose of cutting different positions of the circuit board, causing inconvenience to the user, and the fixing effect of the circuit board is poor. When cutting the circuit board, the circuit board is prone to shifting, affecting the cutting quality. Utility Model Content
