Abstract

An anti-skid mechanism comprises a guide track assembly, a dragging assembly and an anti-skid assembly. The guide track assembly comprises two L-shaped guide tracks. The dragging assembly comprises two lateral boards arranged oppositely, and the lateral boards slide in the L-shaped guide tracks. The anti-skid assembly comprises two clamping devices and two clamping ports. The two clamping devices are fixedly arranged on inner lateral walls of the two lateral boards respectively, and the two inner lateral walls are opposite to each other. The clamping ports are arranged on the L-shaped guide tracks respectively. Each clamping device comprises a clamping piece. When the dragging assembly is pulled out from the guide track assembly for a certain distance, the two clamping pieces of the clamping devices are clamped on the clamping ports respectively so as to prevent the dragging assembly from sliding in the guide track assembly when the dragging assembly is pulled.
