     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to FIG. 1. The multi-functional leisure chair of the present invention is mainly composed of a chair frame body 10, a chair pad 20 disposed on the chair frame body 10, and a water-guiding pad 30 optionally detachably disposed on the chair frame body 10. When the water-guiding pad 30 is disposed on the chair frame body 10, the leisure chair can alternatively serve as a shampooing chair. The chair frame body 10 is composed of a plurality of frame members which are pivotly connected with one another, permitting the frame body 10 to be folded into a flat and small body for easy storage. The frame body 10 is further formed with stopper blocks which protect the hand of a user from being clamped and injured by the frame body 10 when folding the same so that the safety of the user can be ensured. 
     As shown in FIGS. 1 through 6, the chair frame body 10 is composed of: 
     a U-shaped front support leg 11 and a U-shaped rear support leg 11&#39;, the front and rear support legs 11, 11&#39; respectively having upper open sides 111, 111&#39; and lower close sides, in which the upper open sides 111, 111&#39; are connected with each other while the lower close sides are extended forward and rearward in a stretched state; 
     a horizontally disposed U-shaped seat frame 12 having an open side 121 which faces rearward, a plurality of first beam members 122 being disposed between two arms of the seat frame 12, and a second beam member 122&#39; being disposed across the open side 121 of the seat frame 12, two ends of the second beam member 122&#39; laterally projecting from the open side 121 of the seat frame 12; 
     an H-shaped back frame 13 having two lateral column members 131 and a plurality of beam members 132 connected between the column members 131, upper ends of the column members 131 being slightly bent rearward and lower ends thereof being connected with the open side 121 of the seat frame 12; 
     two rail members 14 disposed on the connected open sides of the front and rear support legs 11, 11&#39;; 
     two pivot seats 15 pivotally connected with front ends of the rail members 14 and the open sides of the front and rear support legs 11, 11&#39;, permitting the rail members 14 and the front and rear support legs 11, 11&#39; to be pivoted toward one another through a certain angle; 
     two fixing sets 16 each of which has a T-shaped fixing rod 161 and a fixing plate 162, wherein the fixing plate 162 is secured on an inner middle section of the rear support leg 11&#39;, and formed with an L-shaped slot 1621 having a downward facing hook portion 1622, lower end of the T-shaped fixing rod 161 extending downward to connect with the end of the second beam member 122&#39; which goes through the L-shaped slot 1621, upper end of the fixing rod 161 being pivotally connected under a rear end of the rail member 14, whereby when the end of the second beam member 122&#39; is slided within the L-shaped slot 1621, the chair frame body 10 can be folded into a small body; 
     two angle-adjusting means 17 having inner movable engaging teeth and front and rear projections 171 which are connected between a bottom side of the back frame 13 and the open side of the seat frame 12, whereby the angle contained by the front and rear projections 171 can be adjusted to change the bending angle contained by the back frame 13 and the seat frame 12; 
     two front stopper blocks 18 and two rear stopper blocks 18&#39;, wherein the front stopper blocks 18 are rectangular blocks and disposed on a middle section of the front support leg 11, the front stopper blocks 18 having rear projections 181 which keeps a space 182 between the front and rear support legs 11, 11&#39; when folding the same so as to protect the hand of the user that holds the front support legs 11 from being clamped and injured (as shown in FIG. 5), and wherein the rear stopper blocks 18&#39; are bent blocks and disposed between the fixing plates 162 of the rear support leg 11&#39; and the angle-adjusting means 17, the rear stopper blocks 18&#39; being such bent that when the front and rear support legs 11, 11&#39; are pivoted toward each other, the rear stopper blocks 18&#39; form an obstacle at a bending corner and prevent the hand of the user that holds the rear support leg 11&#39; from slipping into the bending corner and getting hurt (as shown in FIGS. 3 and 4); and 
     a plurality of skidproof sleeves 19 formed with facial projecting stripes 191 and fitted on the lower sides of the front and rear support legs 11, 11&#39; for creating a skidproof effect on the chair frame body 10. 
     The chair pad 20 is formed by a large cushion 21 and a small cushion 22 connected therewith. A plurality of loop-hook fasteners 23 are disposed along the periphery of the chair pad 20 whereby the chair pad 20 can be detachably fastened over the chair frame body 10 by means of securing the fasteners 23 with the seat frame 12 and the back frame 13. The small cushion 22 is laid on the upper bent portion of the column members 131 of the back frame 13 to serve as a pillow. 
     The water-guiding pad 30 is formed with a central recess, a peripheral water-stopping wall 31 and a rear water-guiding opening 32. Two U-shaped clamping members 33 are disposed on a bottom surface of the water-guiding pad 30, whereby after the small cushion 22 is detached from the back frame 13, the clamping members 33 can be secured on the column members 131 of the back frame 13 to fix the water-guiding pad 30 on the back frame 13, forming a shampooing chair (as shown in FIG. 6). 
     Therefore, when the user desires to use the present invention as a leisure chair, the water-guiding pad 30 can be removed from the back frame 13 by means of upward sliding the clamping members 33 along the column members 131 of the back frame 13 and then the small cushion 22 can be disposed on the back frame 13 by means of the fasteners 23. Reversely, when the user wants to use the present invention as a shampooing chair, as previously described, the small cushion 22 can be detached from the column members 131 of the back frame 13 and replaced by the water-guiding pad 30. The angle-adjusting means 17 permits the user to freely adjust the angle contained by the back frame 13 and the seat frame 12 so as to form a comfortable shampooing chair. 
     According to the above arrangement, the present invention is inventive in both structure and function and can be safely and conveniently used. Moreover, the present invention can alternatively serve as a leisure chair or a shampooing chair as required. The above description and accompanying drawings are only used to show an example of the present invention and should not be considered a limitation of the present invention. Any derivation or modification of the example should be included in the scope of the present invention.
