If the pencil deviate from the side notch of trough, can make the pencil receive the dragging, lead to the circuit disconnection easily, cause electrical equipment unable normal operating. This scheme is through setting up backstop portion 80 to set up backstop portion 80 and the side notch of trough in the same one side of trough, can effectively backstop the pencil in the trough like this and walk the side notch of trough and deviate from of trough, thereby reduced the risk of circuit disconnection, consequently promoted electrical equipment's operational reliability and stability.
