Signal stick
First Claim
1. A signal stick comprising:
- a hollow cylindrical metal handle;
a battery set mounted within said handle;
a hollow cylindrical connector having a bottom end fastened to said handle by a screw joint;
a circuit board mounted within said connector and turned with said connector into electrical contact with said battery set;
a transparent sleeve having a bottom end connected to said connector and a top end covered with a cap;
a plurality of metal wire rods mounted within said transparent sleeve and respectively connected to positive and negative terminals of said circuit board;
a plurality of LEDs having respective positive contact pins and negative contact pins respectively welded to said metal wire rods;
switch means mounted on said connector and connected between said circuit board and said metal wire rods and controlled to turn on said LEDs;
wherein said connector comprises an annular top open chamber and an inner race surrounded by said annular top open chamber;
the cap of said transparent sleeve has an inside annular coupling groove;
an inner tube is mounted within said transparent sleeve to hold said metal wire rods in place, having a bottom end plugged into the annular top open chamber of said connector, a top end plugged into the inside annular coupling groove of the cap of said transparent sleeve, and four equiangularly spaced locating grooves at the top end;
said metal wire rods have a respective hooked top end respectively hooked on the locating grooves of said inner tube and include a first positive metal wire rod, a second positive metal wire rod, a third positive metal wire rod, and a negative metal wire rod, said negative metal wire rod having a bottom end connected to the negative terminal of said circuit board, said first, second and third positive metal wire rods having a respective bottom end alternatively connected to the positive terminal of said circuit board by said switch means;
said LEDs include a plurality of red LEDs having a respective positive metal contact pin connected to said first positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod, a plurality of yellow LEDs having a respective positive metal contact pin connected to said second positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod, and a plurality of green LEDs having a respective positive metal contact pin connected to said third positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod;
said switch means comprises a red/yellow/green selector switch controlled to connect to positive terminal of said circuit board to one positive metal wire rod, and a manual/auto control switch shifted between an automatic mode to automatically connect said positive metal wire rods to the positive terminal of said circuit board in a set order, and a manual mode to let said positive metal wire rods be alternatively and manually connected to the positive terminal of said circuit board by said red/yellow/green selector switch.
