Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
A kind of mouth cavity orthodontic opener referring to FIG. 1-2, including sleeve 1, the sleeve 1 are horizontally disposed, sleeve 1 it is interior
A screw rod 2 is equipped in portion's cavity, screw rod 2 is arranged along 1 length direction of sleeve, and the length of screw rod 2 is consistent with the length of sleeve 1, spiral shell
Two sections of bar 2 are mounted on inside sleeve 1 by bearing 3, and the screw rod 2 divides for 202 two parts of left screw rod 201 and right screw rod,
And left screw rod 201 is consistent with right 202 length of screw rod and is integrally formed setting, left screw rod 201 and the thread helix on right screw rod 202
It is contrary, it is arranged with swivel nut 4 on the left screw rod 201 and right screw rod 202, two swivel nuts 4 are symmetrically set along 1 inside center of sleeve
