The projector body includes a waterproof layer and a tempered glass screen. The lower surface of the projector base is provided with a sponge block. The interior of the shock-absorbing frame is provided with a first squeeze block and a second squeeze block. The shock-absorbing hole is provided on the outside of the shock-absorbing frame and the connecting frame, and the top and bottom ends of the connecting frame are provided with a connecting rod and a shock-resistant base, respectively. The inner bottom end of the shock-resistant base is connected to the shock-absorbing frame through a fixed block. The shock-absorbing frame of the waterproof projector with a shock-resistant base is provided with a first squeeze block, a shock-absorbing spring, a second squeeze block and a shock-absorbing hole. At the same time, the shock-absorbing frame is provided with a hollow structure. When the device is vibrated, the first squeeze block and the second squeeze block move under the action of the shock-absorbing spring, and the vibration force is transmitted to each other through the movement of the first squeeze block and the second squeeze block.

[0004] In the above patent, the vibration force is transmitted to each other by the movement of the first extrusion block and the second extrusion block.

However, the projector base is still fixed, which makes it inconvenient to adjust the projection height of the projector. There are certain limitations. Therefore, a projector integrated with a multi-functional base is needed to adjust the projection height of the projector. Utility Model Content
