Abstract: A long-stick mower which includes a base, a fixed shear, a mobile shear, a driver, a linkage, an extension spring and an extension control rod. The base is connected to the lower end of the extension rod. The top of the driver is pivoted to the base and drawn toward the base by the extension spring. The linkage is pivoted to the top of the mobile shear at one end and to the drive at the other end. The extension spring is hooked to the bottom of the base to draw the drive. The extension control rod is inserted to the base. When the top of the extension control rod is pressed down, the driver has its caster to hold against the ground and the driver spreads up backward to draw the linkage to move backward to pull the mobile shear. When the extension control rod is pulled up, the driver is drawn back to push the linkage to move forward while pushing the mobile shear to spread up to complete an easy cycle of cutting.

Abstract: An improved structure of a long-stick mower is comprised of a base, a fixed shear, a mobile shear, a driver, a linkage, a extension spring and an extension control rod characterized by that the base being connected to the lower end of the extension rod; the top of the driver being pivoted to the base and drawn toward the base by the extension spring; the linkage being pivoted to the top of the mobile shear at one end and to the drive at the other end; the extension spring being hooked to the bottom of the base to draw the drive; the extension rod being inserted to the base; the extension rod when pressed at its top for a pulley in the driver to hold against and spread backward while drawing the linkage for a displacement backward to pull the mobile shear to the fixed shear for cutting; and when the extension rod being pulled up for the extension spring to pull back the driver, thus to push the linkage to travel forward while drawing the mobile shear to open up.

Abstract: An improved structure of a pruning hook is essentially comprised of a pair of shears substantially similar to the prior art including a drive arm, a hook, and a mobile knife in sequence and a lopping saw provided at the top of an extension rod characterized by that the top of the drive arm being pivoted to an end sleeve at the top of the rod; a restriction chain with a pulley being drawn and inserted to the rod; and the saw being locked to where by the end sleeve to execute pruning with a single hand by hooking the twigs and pulling down the rod to draw the drive arm and the swinging mobile knife.
