[0024] Furthermore, the cross-section of the supporting foot 12 is arranged in a T-shaped structure, and the supporting foot 12 is adapted to the upper groove 10 and the lower groove 11. When a plurality of supporting feet 12 are respectively inserted into the corresponding lower groove 11, it is convenient to implement welding operations on the top surface of the circuit board body 1. When a plurality of supporting feet 12 are respectively inserted into the corresponding upper groove 10, it is convenient to implement welding operations on the bottom surface of the circuit board body 1.

[0025] Furthermore, the anti-skid layer 13 is located on one side of the T-shaped support foot 12 . The anti-skid layer 13 is made of rubber material to increase the friction between the support foot 12 and the desktop, thereby achieving stable support for the circuit board body 1 .
