When the slide bar 501 is adjusted to a suitable height, the push block 506 is released, the spring 507 is reset and drives the connecting rod 504 to move toward the outside of the slide bar 501, and the connecting rod 504 drives the limit block 503 to slide toward the outside of the slide bar 501, so that the limit block 503 is engaged with the corresponding limit groove 502 on the slide sleeve 1, so that the slide bar 501 can no longer move, thereby making the measuring device more comfortable and convenient to use, and the sliding connection between the slide sleeve 1 and the slide bar 501 facilitates the storage and transportation of the measuring device.
