Abstract

The invention provides a foldable catapult, which comprises a catapult arm, a box-type handle, a screw stem, a stop block, a micro storage box and a hinge mount. In the foldable catapult, a rotatable catapult arm is configured to replace the fixed catapult arm of the traditional catapult like a Y-shaped branch, thus the catapult can be rotatable and foldable. The foldable catapult can be folded to an I-shaped strip so as to have a small size and good portability. The box-type handle has a storage function so that the folded catapult legs can be put into the handle, thereby facilitating portability. A micro storage is configured at the bottom of the handle to store the catapult rubber band and marbles so as to avoid using a cloth packet, thereby greatly reducing unnecessary inconvenience.
