The tool head latches can be pivoted relative to the handles between a locked position, wherein the locking fingers prevent the mounting dowels from being removed from the handles, and an unlocked position, wherein the mounting dowels can be removed from the handles. A spring biases the tool head latches toward the locked position. To unlock the tool head latches and remove the tool head, a user engages a tool head latch and pulls the handles apart.

Abstract: A garden shears includes a pressing member, a holding member, a cutting member and a ratchet. An aperture of the cutting member combines with an aperture of the pressing member for a pivot. The holding member and the ratchet are assembled together at an assembling portion of the pressing member, and teeth of the ratchet engage with a pawl of the cutting member such that the pressing member, the holding member and the ratchet have different pivot points. An opening between the blade and the anvil is smaller than an opening formed between the handle and the holding member. Since the opening formed between the handle and the holding member is larger than the cutting opening between the blade and the anvil, a stronger cutting torque is applied to increase the clipping strength derived from the anvil and the blade.
