Positioning set-distance three-stage assistance type ejector

Abstract

The invention discloses an ejection device, and particularly relates to a positioning set-distance three-stage assistance type ejector used on a wedding celebration. The positioning set-distance three-stage assistance type ejector is composed of an ejection chamber, an ejection tube, a front supporting leg, a rear fixed support and an aiming device. The ejection chamber and the ejection tube of the ejector are movably connected with each other. The front supporting leg and the rear fixed support are fixed on the ejection tube. The aiming device is fixed on the ejection chamber. The distance is set according to an ejection target point, and a pair of sliding calipers can be positioned to adjust the ejection angle of the ejection tube. Three-stage assistance type springs are mounted inside and outside the ejection chamber and inside the ejection tube respectively. A gear is swayed by a hand to rotate, the ejection tube retreats, the three-stage assistance type springs are compressed, a pawl locks a ratchet wheel automatically, and when a trigger is pulled, firework balls or other ejection objects in the ejection chamber are ejected out of the ejection chamber under the action of spring tension. The ejection target is accurate, and the ejection distance is long. According to the positioning set-distance three-stage assistance type ejector, assistance of the springs is used for replacing gunpowder for ejection, and therefore the positioning set-distance three-stage assistance type ejector is safe and reliable, causes no pollution to the atmospheric environment, and can be widely used as an ejection device for ejecting firework balls on wedding celebrations.

Description

Technical field [0001] The invention discloses a launching device, in particular to a positioning and distance three-stage power-assisted catapult used in wedding ceremonies. technical background [0002] The launching device that uses on the wedding ceremony at present all is to be contained in the launching cylinder of mortar formula with firework ceremony bomb, ignites fuze gunpowder explosion and produces thrust, and projectile is ejected out of the cabin. This launch method not only wastes a large amount of gunpowder, but also produces smog that pollutes the atmospheric environment, is prone to fire, and easily causes injury accidents to the launcher and the crowd of onlookers. This launching device does not have positioning and distance-fixing device, and the target and distance of launching are also inaccurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a safe and reliable three-stage power-assisted ...
