For example, each rotatable portion 223 may be held at a 90 degree angle by a detent structure with respect to the corresponding non-rotatable portion 2231, and the 90 degree angle is maintained.
Based on the above-mentioned at least two snap-in type fixtures 223, the rotatable part 2232 of each snap-in type fixture 223 may have magnetism, and when the each snap-in type fixture 223 is inserted into the tank opening and is connected with the inner side of the manhole plate of the tank opening by rotating the rotatable part 2232 of each snap-in type fixture 223, the rotatable part 2232 having magnetism may be adsorbed together with the inner side of the manhole plate of the tank opening made of a metal material, so that each snap-in type fixture 223 may be better fixed together with the manhole plate of the tank opening.
With respect to the non-rotatable portion 2231 of each of the snap-in retainers 223 described above, each non-rotatable portion 2231 may be telescopic, with the telescopic non-rotatable portion 2231 being adapted to accommodate different spout thicknesses. For example, when the thickness of the opening is large, each non-rotatable part 2231 may be extended, and the extended non-rotatable part 2231 may be fixed by a fixing member at the telescopic joint, so as to prevent the non-rotatable part 2231 from slipping off due to external impact during operation.
Based on above-mentioned two interior knot formula fixings 223, when being fixed in the jar mouth manhole plate with whole device on, can stretch into the jar mouth with these two interior knot formula fixings 223 at least, rotate the rotatable part 2232 of every interior knot formula fixings 223 to the direction at jar mouth manhole plate edge, and fix every rotatable part 2232 based on the screens structure, these two interior knot formula fixings 223 make above-mentioned first frame construction 221 and second frame construction 222 can fix on jar mouth manhole plate better, avoided in the operation process, make above-mentioned helicitic texture 2212 take place to become flexible because of external force strikes.
All the above-mentioned optional technical solutions can be combined arbitrarily to form the optional embodiments of the present invention, and are not described herein again.
The above description is for the purpose of promoting an understanding of the principles of the invention and is not intended to limit the invention to the particular embodiments disclosed, but rather the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
