[0009] Preferably, a splicing block is fixedly mounted on the rear surface of the movable plate, and a limiting sliding groove is provided on the upper surface of the movable plate.

[0010] Preferably, the length of the splicing block is equal to the diameter of the bottle mouth, the movable plate is movably embedded in the through opening, and the limiting slider is embedded in the limiting sliding groove.

[0011] Preferably, the protective ring is movably embedded in the annular embedding groove, the sleeve is sleeved on the surface of the guide rod, the upper end of the spring is fixed to the sleeve, and the lower end of the spring is fixed to the inner lower surface of the lifting groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When the bottle mouth needs to be used, the movable plate is pulled and the protective ring is lowered under the pulling force of the spring, so that the protective ring can be stored and placed when not in use, so that it can be directly taken out next time.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5 The aluminum-plastic composite gas cylinder shown includes a bottle body 1, a protective ring 2, a bottle mouth 4 and a movable plate 3. The bottle mouth 4 is fixedly mounted on the upper surface of the bottle body 1, and the protective ring 2 is movably embedded on the upper surface of the bottle body 1 and located outside the bottle mouth 4. The movable plates 3 are movably embedded inside the two sides of the protective ring 2.

[0022] An annular embedding groove 101 is provided on the upper surface of the bottle body 1 and located on the periphery of the bottle mouth 4. Lifting grooves 102 are longitudinally provided on the inner two side surfaces of the annular embedding groove 101. A guide rod 103 is fixedly installed inside the lifting groove 102. A spring 104 is sleeved on the surface of the guide rod 103. The spring 104 exerts a downward pulling force on the sleeve block 201.
