Abstract: A packing machine with an adjustable band-compressing stroke includes a compressing base provided with an accommodating chamber for installing a pulley, and a compressing device. A shaft passes through the pulley and two penetrating holes bored in two sides of the accommodating chamber. A compressing block is set under the pulley. The compressing device is composed of a compressing handle, a compressing bar, an eccentric shaft fitted in the compressing bar and having a polygonal bar on its bottom, and an adjusting board having a polygonal hole and an arc-like hole. The polygonal bar is engaged with the polygonal hole to enable the adjusting board to turn the eccentric shaft for altering the band-compressing stroke.

Abstract: A saw machine includes a base body with rear and front portions. A worktable extends from the rear portion toward the front portion, and has a sawing slot formed therethrough. An upright support arm has an intermediate section pivoted to the rear portion of the base body. An upper hollow arm extends above the front portion of the base body from an upper section of the support arm. A lower hollow arm extends below the front portion of the base body from a lower section of the support arm. A pair of upper and lower levers have rear ends pivoted respectively in the upper and lower hollow arms, and front ends aligned with each other to define cooperatively a straight line that passes through the sawing slot. An elongated saw blade has two ends connected to the front ends of the upper and lower levers so as to pass through the sawing slot.
