Physics friction test demonstrates appearance

The utility model provides a physics friction test demonstrates appearance, including handle, spring, stopper, clutch blocks, connecting rod, disc, battery, button switch and heating plate, the stopper assembly is on the spout, the connecting rod lower extreme passes the stopper to install at clutch blocks up end intermediate position, connecting rod upper end assembly handle, be equipped with the spring on the connecting rod annular side, spring upper end connect the disc, the stopper is connected to the spring lower extreme, and friction test was only demonstrated to original friction test demonstration appearance principle and phenomenon have been solved in this design, can't let the student participate in in person, the unsatisfactory problem of teaching effects, the battery sets up inside the base, button switch assembly terminal surface before the base, the heating plate is installed at the base up end, and this design has increased the utility model discloses the function that the oneself is dry, the u
