A screw-threaded actuator shaft has a distal portion, and a proximal end extending through the aperture of the rear plate. A lateral screw axel has a threaded aperture receiving the distal end of the actuator shaft, and has its ends extending into the respective left and right track of the shoes. Two parallel lift arms have forward ends, and have rearward ends pivotally attached to the lateral axel. Two connecting arms have forward ends pivotally attached to the forward ends of the shoes, and have rearward ends pivotally attached on the middle of the lift arms.
