[0018] The inner wall of the threaded groove 51 is threaded with a threaded post 53, and the bottom end of the threaded post 53 is fixedly connected to a base plate 52. The mounting mechanism 5 includes a fuse tube 511, and the outer wall of the fuse tube 511 is fixedly connected to a protrusion 512.

[0019] The fuse tube 511 can be quickly installed by using the threaded post 53 and the threaded groove 51.

[0020] The threaded column 53 has a movable cavity 54 at its top end. A support plate 56 is slidably connected to the inner wall of the movable cavity 54. A spring 55 is fixedly connected to the bottom end of the support plate 56. The end of the spring 55 away from the support plate 56 is fixedly connected to the bottom end of the movable cavity 54.

[0021] Spring 55 can drive the support plate 56 to reset without being affected by external force.

[0022] The movable cavity 54 has a slot 57 at its top end, a movable slide rail 58 at its bottom end, and a positioning groove 59 at the top of the inner wall of the movable slide rail 58. The transverse cross-sectional dimensions of the positioning groove 59 are the same as those of the slot 57.

[0023] The position of the fuse tube 511 can be defined by the protrusion 512, which is inserted into the positioning groove 59.

[0024] An auxiliary mechanism 6 is provided on the outer wall of the top of the fuse cylinder 4. An air storage bag 61 is fixedly connected to the top of the top of the fuse cylinder 4. A conveying pipe 62 is connected through and fixedly connected to the outer wall of the air storage bag 61.

[0025] The auxiliary mechanism 6 can further stabilize the entire assembly during installation.

[0026] Among them, an annular support airbag 63 is fixedly connected to the outer wall of the top 4 of the fuse cylinder, and the end of the delivery pipe 62 away from the air storage bag 61 passes through and is fixedly connected to the inside of the annular support airbag 63. A fixing block 66 is fixedly connected to the top of the air storage bag 61.

[0027] Through the air reservoir 61, the gas inside the air reservoir 61 can be transported to the interior of the annular support air 63 via the delivery pipe 62.

[0028] The top of the fixed block 66 is provided with a storage groove 67, and a moving rod 65 is slidably connected through the bottom of the storage groove 67. A piston 64 is fixedly connected to the bottom of the moving rod 65, and a force plate 68 is fixedly connected to the top of the moving rod 65.

[0029] The moving rod 65 moves and drives the piston 64 to move, thereby compressing the gas.

[0030] This utility model provides a compact fuse tube, the specific working principle of which is as follows: In use, when installing the fuse tube 511, insert the fuse tube 511 into the movable cavity 54, align the protrusion 512 with the slot 57, and insert the protrusion 512 into the slot 57 and into the movable slide rail 58. The movement of the fuse tube 511 presses against the support plate 56, and the support plate 56, under pressure, simultaneously presses against the spring 55, keeping the spring 55 in a compressed state. Rotating the fuse tube 511 causes the protrusion 512 to be below the positioning groove 59. Releasing the downward pressure on the fuse tube 511 causes the spring 55 to lose external downward pressure and, relying on its own elasticity, can drive the support plate 56 to return to its original position. The support plate 56 then moves the fuse tube 511 upward. This causes the protrusion 512 to be inserted into the positioning groove 59, fixing the fuse tube 511 inside the threaded post 53. The threaded post 53 is then threadedly connected to the threaded groove 51, thus installing the fuse tube 511. When installing the fuse cylinder body 1, the force plate 68 is compressed. The force plate 68 moves, causing the moving rod 65 to move. The moving rod 65 moves, causing the piston 64 to move inside the air storage bladder 61. This allows the gas inside the air storage bladder 61 to be transported to the annular support air bladder 63 through the delivery pipe 62. The expanded annular support air bladder 63 further fixes the fuse cylinder body 1 to the installation location, maintaining the stability of the fuse cylinder body 1 installation.
