It should be noted that, the above embodiment only exemplifies the case of simultaneous side drawing in two different directions, and when simultaneous side drawing in more directions is needed, a plurality of corresponding first sliders 1 may be arranged on the second slider 7 according to the direction in which side drawing is not needed, which is not repeated herein again.
