The invention discloses a comprehensive demonstration table for a classroom mechanical transmission mechanism. The comprehensive demonstration table comprises a shell, a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, a fourth transmission mechanism, a fifth transmission mechanism, a first human body model and a second human body model. The comprehensive demonstration table has the beneficial effects that a classroom environment which is most familiar for students is taken as a design background, and the transmission mechanisms of a chain transmission mechanism, a straight-tooth cylindrical gear transmission mechanism, a straight-tooth conical gear transmission mechanism, a planar connecting rod transmission mechanism, a worm and gear transmission mechanism, a lead screw nut transmission mechanism, a gear rack and the like are demonstrated intuitively and vividly for the students in a limited space, thereby allowing the students to firmly grasp knowledge about the transmission mechanisms, and fulfilling the aims of increasing the learning interest of the students about a mechanics course and improving the teaching and learning quality.
