Embodiment Construction
[0019] Such as Figure 1 to Figure 3 As shown, a manual cargo lifting device with labor-saving and anti-falling functions of the present invention includes a torque amplification mechanism, a one-way self-locking mechanism, and a clutch mechanism for connecting the torque amplification mechanism and the one-way self-locking mechanism. Utilizing the torque amplifying mechanism of the present invention can achieve obvious labor-saving and speed-up effects, so that a single operator can easily lift heavy goods, thereby saving manpower and material resources, improving lifting efficiency, and reducing the labor intensity of the operator. The one-way self-locking mechanism can effectively prevent the operator from accidentally releasing the driving handle 3 during the process of stirring the driving handle 3, causing heavy objects to fall, causing loss of people and goods.
[0020] The torque amplifying mechanism of the present invention mainly performs torque amplifying through th...
