Lever principle experiment teaching aid for physics teaching

The utility model relates to the technical field of experiment teaching aids, and discloses a lever principle experiment teaching aid for physics teaching, which comprises a base, the upper surface of the base is provided with a threaded hole, a vertical pipe is arranged above the base, the lower surface of the vertical pipe is fixedly connected with a threaded rod, and the threaded rod is in threaded connection with the threaded hole. A vertical telescopic pipe is slidably connected into the vertical pipe, and second sliding grooves are formed in the left side and the right side of the vertical telescopic pipe. Due to the addition of structural elements such as a threaded rod, a threaded hole, a clamping point, a clamping groove and a spring in the device, the improved device can be assembled together in an inserted connection and threaded mode and is convenient to disassemble, assemble, transport and carry, collision damage is reduced, and the service life of the device is prolonged. Meanwhile, through the
