The hand pour is rotated by dragging the bracelet and the bracelet wheel, pressing the rotor of the friction film and the brake seat into a combined rotation. In this way, the lifting chain wheel installed on the gear gear of the flower pores drives the chain, thereby steadily enhance the heavy objects.

Hand -pull gourd is a straight -line traction that matches the load through the principle of leverage through the principle of leverage, which acts on the movement of a pliers in the movement to drive the load operation.

This structure makes the hand -pour gourd has a significant advantage in vertical lifting weights. The hand -tip gourd obtained a straight line traction that matches the load through the principle of leverage, and manpower drives the wire rope or chain through the manpower to drive the movement of the material device. This structure makes the gourd in the hand perform well in horizontal movement.
