The invention discloses a multifunctional catapult comprising a catapult handle and a catapult head. The catapult head comprises a left catapult head and a right catapult head. The left catapult headand the right catapult head are provided with rubber band pressing mechanisms which are identical in structure and mutually symmetrical. The multifunctional catapult further comprises a left-right distance adjusting mechanism, a front-back distance adjusting mechanism and a catapult sighting tool. The left catapult head and the right catapult head are both connected with the left-right distance adjusting mechanism. The left-right distance adjusting mechanism is fixed to the front-back distance adjusting mechanism. The front-back distance adjusting mechanism is fixed to the catapult handle. Bythe adoption of the multifunctional catapult, sighting point support does not block a target any more, the rubber band is quite firmly pressed, and the possibility of the situation that since the rubber band is not firmly clamped, the rubber band disengages and hurts people is greatly lowered; the catapult head achieves the function of quantitatively adjusting the distance and also achieves the function that toothed faces of the left catapult head and the right catapult head clamp each other to achieve fixation. The front-back distance between the catapult head and the catapult handle can be adjusted, and the catapult handle and the catapult head can be simultaneously well fixed. The multifunctional catapult has the features of flexible fine adjustment, firm fixation and the like.
