In a O shape garden trowel in which the grip is mounted on the main body(1) inclined in about 8 deg., a push stick(4) is inserted into the hole(13-1) of the grip plug(13), which is assembled into the screwed part of the grip(3), and then into a spring(5). The push stick(4) moves only up and down using rotation preventing bolt and bolt hole(14)(14-1). Both foldable dynamic blades(5) attached to the main body(1) are moved by a series of actions through mechanism made up of the push stick(4), a hook pin(7), a hook groove(10), the spring(5), a wire(9) and a connection pin(15).
