Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-5, an oral cavity distracting device for department of stomatology comprises a shell 5, a support frame 1 is fixedly installed outside the shell 5, a hollow groove 10 is formed inside the shell 5, a threaded rod 14 is installed at the center position of the top end of the shell 5, one end of the threaded rod 14 is installed inside the hollow groove 10, a rotating shaft 4 is fixedly installed at the top end of the threaded rod 14, a first limiting block 2 is fixedly installed at the bottom end of the threaded rod 14, a circular ring 7 is rotatably installed at the bottom end of the first limiting block 2, a connecting piece 8 is connected inside the circular ring 7, a first distracter part 12 and a second distracter part 16 are arranged at the bottom end of the shell 5, a second limiting block 13 is fixedly installed at one side, close to each other, of the first distracter part 12 and the second distracter part 16, and a compression spring 9 is fixedly installed between, the utility model discloses a portable computer, including connecting piece 8, casing 5, first spreader part 12, second spreader part 16, movable groove 6, first spreader part 12 and second spreader part 16 juncture have been seted up to casing 5, just movable groove 6 and the active position phase-match of first spreader part 12 and
