ABSTRACT:
The direction setting device includes a first connector having a tubular member with a casing extending at an incline from the same and in communication with the tubular member, a spring biased key member which is movably provided in the casing, and a second connector. The casing has a pair of aligned elongated slots, and the key member has a through-hole and an elongated through slot. The second connector includes a tubular top portion with a control notch rotatably and slidably inserted into the lower portion of the first connector where the key member extends into the control notch of the second connector. A plate with a control groove which has two differing troughs is pivoted to the housing in such a manner that a pin passes through the through-hole of the key member, and through the elongated slot of the housing to extend into one of the troughs. Movement of the pin in the troughs can lock the second connector or permit it to rotate with respect to the first connector.
