Compared with the existing multi-layer circuit board pressing device, the utility model can improve the functionality and practicality of the multi-layer circuit board pressing device through design;

Although the device can improve the functionality and practicality of the multi-layer circuit board pressing device when in use, the device needs to manually rotate the screw rod to adjust the distance of the second fixing block when fixing the circuit board, which undoubtedly increases the workload of the staff and may affect the work efficiency. At the same time, some current circuit board pressing devices can only be fixed by locking the universal wheel itself after moving, which can easily cause the device to shake or move when subjected to external force, thereby affecting the accuracy and quality of the pressing. Therefore, we propose a multi-layer circuit board pressing device to solve the above problems.
