The present invention discloses a portable comprehensive mechanical demonstrator which comprises a base (1), a fixed frame (2), a sample rod (3), at least six strain gauges (20), a force applying device, a signal processing circuit for processing the strain gauges (20), a computer and a projection device. The at least six strain gauges (20) are installed on the sample rod (3) and are electrically connected to the input end of the signal processing circuit. The output end of the signal processing circuit is electrically connected to the computer which is electrically connected to the projection device. The fixed frame (2) and the force applying device are installed on the base (1). The force applying device is installed on the fixed frame (2). The lower end of the sample rod (3) is fixed on the base (1). The upper end of the sample rod (3) is fixed on the fixed frame (2). The portable comprehensive mechanical demonstrator can test three forces at the same time and has the advantages of small size and light weight.
