What is claimed is: 1. A handle system mounted on a wheeled luggage, the handle system including two tube assemblies of rectangular section at both sides and a handle grip interconnected the tube assemblies, either tube assembly comprising: a support tube having its bottom end fixedly coupled to a bottom of luggage, the support tube including, at either side wall of an upper portion thereof, a first recess and a plurality of first apertures longitudinally disposed below the first recess; a first stop sleeve including a first flange provided on its top mouth, the first flange being adapted to rest on a top of the support tube, the first stop sleeve further including, at its either side wall, a second recess proximate the first flange and a plurality of first latches disposed below the second recess, the first latches being disposed in the first apertures for securing the first stop sleeve to the support tube; and a sliding tube sub-assembly adapted to insert through the first stop sleeve into the support tube, the sliding tube sub-assembly including, at its either side wall, a recessed portion proximate its bottom mouth, wherein each of the recesses or the recessed portion is formed by punching for adding structural strength to the first stop sleeve, the support tube, or the sliding tube sub-assembly. 2. The handle system of claim 1, wherein the first recess is transverse. 3. The handle system of claim 1, wherein the second recess is longitudinal. 4. The handle system of claim 1, wherein the support tube further comprises an internal first locking device, and the sliding tube sub-assembly further comprises: an outer sliding tube adapted to insert through the first stop sleeve into the support tube to be coupled to and to be locked by the first locking device, the outer sliding tube including, at its either side wall, a third recess proximate its top mouth, a plurality of second apertures longitudinally disposed below the third recess, a fourth recess proximate its bottom mouth, and an internal second locking device; a second stop sleeve including a second flange provided on its top mouth, the second flange being adapted to rest on a top of the outer sliding tube, the second stop sleeve further including, at its either side wall, a fifth recess proximate the second flange and a plurality of second latches disposed below the fifth recess; and an inner sliding tube adapted to insert through the second stop sleeve into the outer sliding tube to be coupled to and to be locked by the second locking device, the inner sliding tube including, at its either side wall, a sixth recess, wherein each of the recesses is formed by punching for adding structural strength to the second stop sleeve, the inner sliding tube, or the outer sliding tube. 5. The handle system of claim 4, wherein the third recess is transverse. 6. The handle system of claim 4, wherein each of the fourth, fifth, and sixth recess is longitudinal. 7. The handle system of claim 4, further comprising a rectangular fourth flange provided on the top mouth of the outer sliding tube for permitting the second flange to rest thereon. 8. The handle system of claim 1, further comprising a rectangular third flange provided on a top mouth of the support tube for permitting the first flange to rest thereon. 9. The handle system of claim 1, wherein tube assemblies of the handle system have a rectangular section.
