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. 1-4, a mouth gag of simple and convenient expansion, including two arc walls 1 that set up relatively, the bottom of two arc walls 1 all is connected with connecting plate 2 of arc structure, the bottom sliding connection of two connecting plate 2 has locating plate 3, overflow launder 4 that sets up along its width direction is seted up at the top of locating plate 3, the both ends of locating plate 3 all are connected with limiting plate 5, threaded connection has the gim peg 6 of fixing on connecting plate 2 on the limiting plate 5, the equal sliding connection in one side that two arc walls 1 kept away from each other has slide 7 of arc structure, the equal threaded connection in one side that two slides 7 kept away from each other has the gim peg 8 that the symmetry set up, be connected with handle 9 between two slides 7, and the both ends of handle 9 are fixed on the.

The constant head tank that is located 3 tops of locating plate is all seted up to the both sides of overflow launder 4, and the inner wall sliding connection of connecting plate 2 and constant head tank, the locating hole 10 of even setting is seted up along its length direction in the bottom of connecting plate 2, and the inner wall threaded connection of gim peg 6 and locating hole 10, spout 11 that the symmetry set up is all seted up to one side that two arc wall 1 kept away from each other, and spout 11 sets up along the length direction of arc wall 1, and slide 7 and spout 11's inner wall sliding connection, threaded connection has the gim peg 8 that the symmetry set up on slide 7, and the bottom of gim peg 8 is contradicted on arc wall 1, handle 9 is made by elastic material, handle 9 is arc column structure.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
