The trigger 326 is disposed on the end of the second rod assembly 320 facing the first rod assembly 310, and at the position where the second rod assembly 320 corresponds to the trigger switch 315, the trigger 326 may abut against the trigger switch 315 when the first rod 100 and the second rod 200 are unfolded. When the pole garden tool is in the working state, the first pole 100 and the second pole 200 are locked in the unfolded state by the foldable pole connecting structure 300, and the trigger 326 abuts against the trigger switch 315 to trigger the trigger switch 315 to be opened and connect the wire circuit in the pole garden tool; when the pole garden tool is in the folded state, the foldable pole connection structure 300 unlocks the rotation between the first pole 100 and the second pole 200, the first pole assembly 310 and the second pole assembly 320 rotate relatively to each other, so that the trigger 326 is separated from the trigger switch 315, and the trigger switch 315 is turned off, so that the electric wire circuit in the pole garden tool is disconnected.

In addition, the type of the pole type garden tool according to the present invention may not be limited, and the pole type garden tool may be any garden tool in which the working part is provided on the pole body, for example, in an embodiment of the present invention, the pole type garden tool is a pole chain saw, and the working part 110 provided on the end of the first pole body 100 is a saw head.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Those skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
