Disclosed is a switch control mechanism for a garden tool, the mechanism comprising handles (12), a switch and shift rods (8). Triggers (6) are arranged on the handles, and the handles can rotate around the axes thereof. The triggers are connected to the shift rods by pull ropes (5), and the contact faces between the pull ropes and the triggers are spherical faces. The handles of the switch control mechanism for the garden tool can rotate within 360 degrees, so as to satisfy different operators, and can ensure that a user can control the switch of a machine wherever the handles are placed.
