The outside portion of card slot, the second connecting rod is equipped with slideway, locating piece is slidably connected in slideway, the front end of locating piece is equipped with more
A fixture block with card slot cooperation, the second connecting rod are equipped with the locking device coordinated with locating piece.
The locking device includes being arranged to be equipped in second connecting rod upper surface and the strip hole that penetrates through with slideway, strip hole
Puller bolt.
Angle between the dip section and first connecting rod, second connecting rod upper surface is acute angle.
It is set with rubber sleeve on two dip sections.
The side of the locating piece is equipped with the sliding block being slidably connected in slideway, and the front side portion in locating piece is arranged in fixture block,
The rear lateral portion of locating piece is equipped with curved arc shape handle.
The longitudinal cross-section of the card slot is triangle, and the longitudinal cross-section of the fixture block is triangle.
After adopting the above scheme the advantages of, effect was：The front end of two arc-shaped connecting rods is equipped with and arc-shaped connecting rod upper table
The vertical dip section in face, dip section can stretch into oral cavity portion, and two dip sections symmetrically stretch into the both sides in oral cavity, then adjust
The distance between two handles adjust oral cavity expanding degree so as to adjust the distance between two dip sections.It adjusts between two handles
Distance after, push locating piece forward, the fixture block on locating piece made to snap fitted in card slot, it is fixed that arc can be realized in stationary positioned block
The fixation of position plate, to realize the fixation of two handles, can thus make dip section holding oral cavity struts amplitude.This structure
Opener patient can be assisted to adjust opening amplitude, and keep the amplitude to coordinate the treatment of medical staff.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the vertical view of first connecting rod in Fig. 1.
Specific implementation mode
As Figure 1-Figure 2, which includes two hinged first connecting rods 1 and second connecting rod 2, the
The rear end of one connecting rod 1 and second connecting rod 2 is equipped with handle 10, and handle 10 is equipped with the finger ring stretched into for finger, is convenient for hand
Hold handle 10.The front end of first connecting rod 1 and second connecting rod 2 is equipped with arc-shaped connecting rod 11, the front end of two arc-shaped connecting rods 11
Portion is equipped with the dip section 12 vertical with 11 upper surface of arc-shaped connecting rod, and dip section 12 can stretch into oral cavity portion, and two stretch into
Section 12 symmetrically stretches into the both sides in oral cavity, the distance between two handles 10 is then adjusted, so as to adjust between two dip sections 12
Distance adjusts oral cavity expanding degree.Angle between dip section 12 and first connecting rod 1,2 upper surface of second connecting rod is acute angle, this
Kind of angle can make to form a space between dip section 12 and first connecting rod 1,2 upper surface of second connecting rod, dip section 12 with
Oral cavity wall is bonded, and first connecting rod 1,2 upper surface of second connecting rod are closely facial, i.e., places facial muscles and be clamped on relatively
