The purpose of this utility model is achieved like this:

With a strip sheet metal, be rolled into the special-shaped groove of a platypelloid type by section shown in Figure 2, respectively there is the flanging of a perpendicular type at the notch place, one to the groove invagination, outside groove, roll over for one, two corner angle up and down of interior flanging one side of groove have radian slightly, with of the length and width size segmentation of this abnormal shape groove by doing desktop, do following processing at its segmentation intersection point place: with the hem width of interior flanging intersection point distance as the distance edge, bottom land sheath face is done the cross shearing at 90 ° of angles on the both sides that intersection point is sentenced 45 ° of inclinations, make it the sheath face portion and become a square vacancy with the outer flanging that bracketing is used, simultaneously, the sheath face outer edge side at antinode place and corresponding with it interior flanging part also cut into the vacancy of diagonal form, be used at the waypoint place it bending, can become circular arc, need in addition the shearing arm of angle of interior flanging and the shearing both sides of the diagonal angle part of corresponding sheath face vacancy with it in order to make the break after the bending, do arc expansion to both sides, this arc expansion can make and be angled from the circular arc attitude after the bending.After above-mentioned cutting process is all done at four knuckle places of special-shaped groove of honest material down, it can be surrounded weldering and live polishing, even if then table limit sheath face typing.For complete good-looking, the inside and outside flanging notch place joint strip below this sheath need be sealed.When sheath processes general assembly,, get final product with table frame combination forming again as long as supporting desktop is put on the outer flanging of sheath circle (as Fig. 2 dotted line).This sheath can be made of stainless sheet steel or aluminium alloy sheet, if need be done antirust spray treatment to the cover face when making of sheet iron.

Concrete technical characterictic of the present utility model is: described sheath is formed by the special-shaped groove of the platypelloid type length and width size bending system of enclosing according to desktop, one of them trough rim is the square invagination, be used to make the sheath typing, another trough rim is that square is rolled over outward, be used for the bracketing desktop, the right angle face that bending is enclosed in the sheath face after the system is the bottom land butt joint of 45, and the knuckle end that encloses after the system is the circular arc attitude.

The utility model is changed tradition, make four wedge angles into fillet after, bump the angle and breach falls the lacquer problem except that having solved, with seam to being one to have increased the decoration of aesthetic feeling after good.

Problem early has the people to find in fact in the background of the present utility model, does not how find a more adequate solution way, thus just always tradition still keep intact till now.
