The locking mechanism of the control valve comprises a fixed support, a movable support and a movable pin, a horizontal kidney-shaped hole is formed in the fixed support, the movable support is hinged to the fixed support, and an arc-shaped groove and a locking groove are formed in the movable support. When the control valve needs to be operated, the movable pin is connected to the horizontal kidney-shaped hole and the arc-shaped groove in a penetrating mode, the movable support can rotate around the fixed support, the control valve connected with the movable support can also rotate together, and therefore the function of operating the control valve is achieved. When the control valve does not need to be operated, the movable pin is connected to the horizontal kidney-shaped hole and the locking groove in a penetrating mode, the movable support is locked relative to the fixed support, namely, the movable support is clamped by the movable pin and cannot move, the control valve connected with the movable support
