The invention relates to a linear motion reinforcement module with a pulley block. The linear motion reinforcement module comprises a rack, a driving motor, a winch, a fixed pulley module, a movable pulley module, a traction rope, a linear guiding mechanism and a linear executing element. The fixed pulley module, the driving motor, the winch and the rack are fixed relatively. The movable pulley module gets close to or away from the fixed pulley module through the linear guiding mechanism. The linear executing element is fixed to the movable pulley module. The fixed pulley module comprises a plurality of fixed pulleys, and the movable pulley module comprises a plurality of movable pulleys. A lifting pulley block is composed of the fixed pulleys and the movable pulleys. One end of the traction rope is connected with the winch driven by the driving motor, the other end of the traction rope is fixed to the fixed pulley module or the movable pulley module, and the middle of the traction rope winds around the lifting pulley block. The linear motion reinforcement module is simple in structure, low in construction cost, high in universality, convenient to popularize and capable of improving productivity and serving as the substitute good of hydraulic and pneumatic cylinders and belongs to a driving mechanism for providing linear driving force.
