Abstract

The utility model relates to the technical field of high-voltage power distribution cabinets, in particular to closing equipment, which comprises a ball spline shaft assembly, a front-back driving mechanism, a rotary driving mechanism and a tool head, the driving end of the front-back driving mechanism is connected with one end of the ball spline shaft assembly and used for controlling the ball spline shaft assembly to reciprocate in the axis direction of the ball spline shaft assembly. The driving end of the rotation driving mechanism is connected with the other end opposite to one end of the ball spline shaft assembly and is used for controlling the ball spline shaft assembly to circumferentially rotate along the axis direction of the ball spline shaft assembly, so that when switching-on operation needs to be carried out, only the position of the pressing button or the rotation button needs to be in butt joint with a tool head of the equipment; after butt joint is completed, the personnel evacuate from the high-voltage power distribution cabinet to reach a safe distance, and then the front-back driving mechanism and the rotary driving mechanism can be controlled by equipment such as an industrial tablet computer to drive the ball spline shaft assembly to rotate, advance and retreat, so that automatic closing is realized.
