[0032] Reference Figure 1 - Figure 3 The fixing assembly 4 also includes a fixing ring 42 for fixing the block 44. The bottom end of the fixing ring 42 is fixedly connected to the top of the fixing sleeve 3. The outer wall of the fixing ring 42 is provided with a fixing groove 43 for accommodating the block 44. The inner wall of the protective sleeve 41 is slidably connected with a block 44 for fixing the protective sleeve 41. The cross-section of the block 44 is trapezoidal. When the inclined surface at the bottom end of the block 44 is squeezed, the block 44 will be forced to move outward. The block 44 and the fixing groove 43 are adapted. When the block 44 is stuck in the inside of the fixing groove 43, the protective sleeve 41 will be fixed to the top of the fixing sleeve 3. The rear end of the block 44 is fixedly connected with a fixing spring 45 for pushing the block 44 inward. The rear end of the fixing spring 45 is fixedly connected to the inner wall of the protective sleeve 41, and the fixing spring 45 will always push the block 44 inward.

[0033] Reference Figure 2 - Figure 4The unlocking assembly 5 includes a sliding ring 52 for squeezing the card block 44. The sliding ring 52 is slidably connected to the outer wall of the fixed groove 43. The sliding ring 52 is a hollow ring and can slide up and down on the outer wall of the fixed groove 43. The sliding ring 52 and the card block 44 are adapted to each other. By using the sliding ring 52 to squeeze the inclined surface at the bottom end of the card block 44, the card block 44 can be forced to move outward and out of the interior of the fixed groove 43. The top of the sliding ring 52 is provided with a threaded groove 56 for fixing the unlocking rod 51. The inner wall of the threaded groove 56 is threadedly connected with an unlocking rod 51 for driving the sliding ring 52 to move. The top of the fixed ring 42 is provided with a through groove 57 for allowing the unlocking rod 51 to enter the interior of the device. The unlocking rod 51 slides on the inner wall of the through groove 57. The unlocking rod 51 passes through and is inserted into the protective sleeve The top of the protective sleeve 41 is provided with an opening for the unlocking rod 51 to pass through. The unlocking rod 51 can be moved to the top of the sliding ring 52 by passing through the through slot 57. The inner wall of the protective sleeve 41 is slidably connected near the top position to form a stopper 53 for blocking the top opening of the protective sleeve 41. The top of the stopper 53 is provided with a groove 54. The groove 54 is set to a semi-conical shape. The stopper 53 can be forced to move outward by using the unlocking rod 51 to squeeze the groove 54. The rear end of the groove 54 is fixedly connected to a protective spring 55 for pushing the stopper 53. The rear end of the protective spring 55 is fixedly connected to the inner wall of the protective sleeve 41. When the stopper 53 is not restricted, the protective spring 55 will push the stopper 53 inward to block the top opening of the protective sleeve 41.

[0034] Working principle: When the connecting pipe 1 needs to be fixed, the fixing sleeve 3 can be fixed to the top of the gas meter by rotating the fixing sleeve 3. At this time, the fixing sleeve 3 will squeeze the rubber pad 6 to make it fit tightly to the interface of the gas meter. Then the protective sleeve 41 can be moved downward to be sleeved on the outer wall of the fixing sleeve 3. At the same time, the block 44 will be stuck in the inside of the fixing groove 43 to fix the protective sleeve 41 to the top of the fixing sleeve 3. At this time, the fixing sleeve 3 will not be accessible from the outside and the entire device will be fixed.

[0035] When it is necessary to unlock the fixing sleeve 3, the unlocking rod 51 can be inserted into the interior of the protective sleeve 41. In the process of passing through the protective sleeve 41, the unlocking rod 51 will force the block 53 to move outward by squeezing the groove 54. When the unlocking rod 51 enters the interior of the protective sleeve 41, the unlocking rod 51 can be used to pass through the through groove 57 to contact the sliding ring 52. Then the unlocking rod 51 can be rotated so that the unlocking rod 51 is threadedly connected to the inside of the threaded groove 56. Then, the unlocking rod 51 can be pulled upward to drive the sliding ring 52 to move upward. The upward movement of the sliding ring 52 will squeeze the inclined surface at the bottom end of the block 44, forcing the block 44 to move outward. When the block 44 is out of the fixing groove 43, the protective sleeve 41 can be moved upward to expose the fixing sleeve 3 again.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
