The invention relates to the technical field of rope carrying emitters, in particular to a multifunctional pneumatic thrower. The multifunctional pneumatic thrower comprises an inflator, a hand support assembly and a gas cylinder, the air cylinder comprises a cylinder body and a piston assembly located in the cylinder body, one end of the cylinder body is an open end, an abutting sealing ring is formed in the cylinder body close to the opening end, a central box is fixedly arranged in the compressed air storage area, a central cavity is formed in the central box, an air outlet pipe penetratesthrough the central box, the air outlet pipe orifice is provided with a rubber plug for controlling opening and closing of the air outlet pipe orifice, and a through hole is formed in the side, facingthe abutting sealing ring, of the center box. The piston assembly comprises a piston rod, a first piston and a second piston, the first piston and the second piston are connected to the two ends of the piston rod, and the second piston is located in the center cavity; and when the first piston abuts against the abutting sealing ring, a distance is reserved between the second piston and the innerside wall of the center box, and the cross-sectional area of the second piston is greater than the central area of the abutment seal ring. According to the scheme, long-distance throwing of objects can be achieved under the condition that the air pressure in the cylinder body is small.

    本发明涉及绳索携带发射器的技术领域,尤其是涉及一种多功能气动抛投器。一种多功能气动抛投器,包括气筒、手托组件和气瓶,气筒包括筒体和位于筒体内的活塞组件,筒体的一端为开口端,筒体内靠近开口端成型有抵接密封环,压缩空气储存区内固设有中心盒,中心盒内部成型有中心空腔,中心盒上穿设有出气管,出气管口设有控制出气管口启闭的橡胶塞,中心盒面向抵接密封环一侧设有通孔:活塞组件包括活塞杆和连接在活塞杆两端的第一活塞、第二活塞,第二活塞位于中心空腔内,第一活塞与抵接密封环抵接时,第二活塞与中心盒内侧壁之间留有距离,第二活塞截面积大于抵接密封环中心面积。上述方案能够在筒体内气压较小的情况下将物件实现远距离抛投。
