[0016] like Figure 1 - Figure 2As shown, the utility model provides a display device for mechanical teaching, including a placement platform 1, a clamping assembly 2 is arranged on the placement platform 1, a telescopic rod 3 is arranged at the bottom of the placement platform 1, three support rods 4 are hinged at the bottom of the telescopic rod 3, a movable sleeve 5 is sleeved on the telescopic rod 3, three support legs 6 are hinged on the side of the movable sleeve 5, and the end of the support rod 4 is hinged on the support leg 6. The placement platform 1 is used to place a mechanical model. When in use, the movable sleeve 5 is pushed downward, and the three support legs 6 are opened under the action of the support rod 4, and the three support legs 6 form a stable supporting structure. When the mechanical model is placed on the placement platform 1, it can be fixed by a clamping device, so that the mechanical model is not easy to fall. The overall weight is light, and it can be easily moved to a suitable position, which is more conducive to students to see the structural principle of the mechanical model. The clamping device of the placement platform 1 can be closed, the telescopic rod 3 can be retracted, and the support legs 6 can be closed together. In summary, the overall volume after retraction is small and light, which can be easily stored or carried, and is more conducive to teachers to place and carry for use.
