The invention provides an operating board lifting mechanism. The operating board lifting mechanism comprises an operating board provided with a control device. A link mechanism is arranged between the operating board and an operating board installation base and comprises a support supporting rod which is fixedly connected with the installation base and arranged in the vertical direction. A first connecting rod and a second connecting rod which are arranged in parallel are hinged and connected to the upper end and the lower end of the support supporting rod respectively. The free end of the first connecting rod and the free end of the second connecting rod are hinged and connected to the two ends of a third connecting rod which is vertically arranged. The operating board is connected to the third connecting rod. The link mechanism is of a parallelogram structure. The hinged end of the support supporting rod and the first connecting rod and the hinged end of the second connecting rod and the third connecting rod are connected with the two ends, in the extending-out direction, of a lifting oil cylinder respectively so that the operating board can be driven to rise and fall in the vertical direction. The operating board lifting mechanism can adapt to operators with different heights and different terrains, angular deflection can not happen to the tabletop of the operating board on the horizontal plane, and operation comfort of the operating board is improved. The invention further provides a drilling machine.
