Abstract: A bolted telescopic rod-type defense spray apparatus includes a first tube body, a cap, a compression elastic piece, a second tube body, an anti-extraction element, a spring pin component, and a push joint component. In the bolted telescopic rod-type defense spray apparatus, two sectioned tube pieces and a spring pin component and a push joint component that are between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a press-lever spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces.

Abstract: An interlocking telescopic rod-type defense spray apparatus includes: a first tube body, a cap and a second tube body. The first tube body has a receiving chamber for placing an irritant gas can. The cap covers the receiving chamber. A rod body portion of the second tube body includes an upper tube, a lower tube, and a telescopic-rod packing device connecting the upper tube and the lower tube. Two sectioned tube pieces and a spring pin component and a push joint component between the two tube pieces are applied to lock and unlock a relative position relationship between the two tube pieces, so that the defense spray apparatus has composite functions of a rod-piece additional function of a locking configuration of relative positions of the two tube pieces and a press-lever spray irritant gas can of an unlocking configuration of the relative positions of the two tube pieces.
