Multiple-use dynamic water surfboard device

Abstract

A dynamic water surfboard has a power system for providing power to the dynamic water surfboard. The dynamic water surfboard further has a plurality of connecting holes or screw holes. Thereby the dynamic water surfboard can be connected to a great or air inflation surfboard so as to drive the great or air inflation surfboard or the dynamic water surfboard can be used singly. The dynamic water surfboard has a motor and a propeller as a power movement mechanics. A safety mask is locked to a rear side of the propeller by using screws and a handle is installed at a front end of the dynamic water surfboard. Thus the design of the dynamic water surfboard is economic and has wide applications.

1 . A multiple-use dynamic water surfboard device having a power system for providing power to the dynamic water surfboard and a plurality of connecting holes or screw holes; 
 whereby the dynamic water surfboard can be connected to a great or air inflation surfboard by using the connecting holes of screw holes so as to drive the great or air inflation surfboard, or the dynamic water surfboard can be used singly.    
   
   
       2 . A multiple-use dynamic water surfboard device as claimed in  claim 1 , further comprising: 
 a dynamic water surfboard; a bottom side of the dynamic water surfboard having a motor and a propeller as a power movement mechanics; the dynamic water surfboard further having a touch type power switch at a lower side thereof for controlling the actuation of the motor;    a safety mask locked to a rear side of the propeller by using screws;    a handle installed at a front end of the dynamic water surfboard; the handle installed to a through hole at a front end of the dynamic water surfboard;    a folded portion installed at a lower section of the handle; the folded portion having a set of base plates which are pivotally installed at lateral sides of the folded portion; one side of one base plate being pivotally installed with a screw rod; a buckling rod and a locking nut being assembled to an upper side of the screw rod; another base plate having a notch; when the two base plates clamp the handle, the screw rod will enter into the notch; by the locking nut, the buckling rod will enter into a positioning groove at a top surface of the base plate; and thus the handle is positioned;    a direction change rod being installed at a lower side of the folded portion; the direction change rod passing through the through hole of the dynamic water surfboard and then protruding to a lower side of the dynamic water surfboard; a directional rudder plate passing through an assembled hole of the direction change rod;    an elastic buckle installed at a lower hole of the direction change rod; two sides of the elastic buckle having respective projections; the projections protruding out from the lateral holes of the direction change rod; after the directional rudder plate being assembled to the direction change rod, the projections of the elastic buckle will eject out from a lower side of the directional rudder plate so that the directional rudder plate is positioned; in detaching, the two projections of the elastic buckle are pressed, and then the directional rudder plate can be taken out; the whole handle can be drawn out to separate from the dynamic water surfboard; and    wherein the dynamic water surfboard can be used singly as a surfboard, or it be assembled to a great or air inflation surfboard as a power source of the great or an air inflation surfboard so as to be as a dynamic boat.    
   
   
       3 . The multiple-use dynamic water surfboard device as claimed in  claim 1 , wherein a detachable chair is installed on the dynamic water surfboard; a periscope is installed on the dynamic water surfboard; and collision-proof protection body is installed at a periphery of the dynamic water surfboard.  
   
   
       4 . The multiple-use dynamic water surfboard device as claimed in  claim 3 , wherein the collision-proof protection body is made of a plurality of rubber blocks or a thicker air cushion.
