An interlocking telescopic rod-type defence spray apparatus 1 includes a first tube body 10, a cap 20 and a second tube body 40. The first tube body 10 has a receiving chamber 111 for placing an irritant gas can A. An inwardly-shrinking hole 123 is formed on an end surface of a tail-end portion 12 of the first tube body 10. The cap 20 covers the receiving chamber 111 and has a step through hole. A compression elastic piece 30 is disposed between a press-ring portion of the irritant gas can A and the step through hole. A rod body portion of the second tube body 40 includes an upper tube 411, a lower tube 412, and a telescopic-rod packing device 413 connecting the upper tube 411 and the lower tube 412. The second tube body 40, is inserted from a head-end portion 11 from the first tube body 10, so that the lower tube 412 is exposed from the tail-end portion 12 of the first tube body 10, and the upper tube 411 and the telescopic-rod packing device (413) are limited inside the first tube body 10 by using the inwardly-shrinking hole 123. The apparatus may take the shape of an umbrella. |
