The movable block 6 is connected through the threaded connection of the outer wall of the screw rod 5, so that the screw rod 5 rotates the outer wall of the conveying shell 1 and the movable block 6 moves, thereby driving the telescopic block 7 to telescope, thereby fixing the clamping shell 8 and preventing the clamping shell 8 from falling while moving.

[0025] In a preferred embodiment, a moving groove 9 is formed on the outer wall of the clamping shell 8 , and a limiting groove 11 is formed on the inner wall of the clamping shell 8 .

[0026] It should be noted that, by providing the movable groove 9, the clamping block 1010 will not get stuck during the process of clamping the instrument, and by providing the limiting groove 11, the steel bar 1005 can be limited so that the steel bar 1005 can only be movably connected on the inner wall of the limiting groove 11.

[0027] In a preferred embodiment, the clamping assembly 10 includes a spring 1001, a movable plate 1002 is fixedly assembled on the top of the spring 1001, a limit block 1003 and a connecting column 1006 are respectively fixedly assembled on the top of the movable plate 1002, the inner wall of the limit block 1003 is rotatably connected to a rotating shaft 1004, the outer wall of the rotating shaft 1004 is fixedly assembled with one end of a steel bar 1005, the other end of the steel bar 1005 is fixedly assembled with a clamping block 1010, the top of the connecting column 1006 is fixedly assembled with a limit plate 1007, the outer wall of the steel bar 1005 is provided with a spring 2 1008, and the top of the spring 2 1008 is fixedly assembled with a limit rod 1009.

[0028] It should be noted that by placing the instrument into the clamping shell 8, the gravity of the device itself applies pressure to the limit plate 1007, so that the connecting column 1006 and the movable plate 1002 apply pressure to the spring 1001. When the movable plate 1002 moves, the steel bar 1005 is driven to move downward, and at the same time, the clamping block 1010 is driven inward to clamp. At the same time, through the limit rod 1009, spring 2 1008 and movable groove 9, the clamping block 1010 will enter the inner wall of the movable groove 9 when clamping inward, so that when the limit rod 1009 is pressurized, the limit rod 1009 drives the spring 2 1008 to move, thereby limiting the clamping block 1010.

[0029] In a preferred embodiment, the bottom of spring one 1001 is fixedly assembled with the bottom of the clamping shell 8 , the clamping block 1010 is matched with the notch of the movable groove 9 , and the spring two 1008 is fixedly assembled with the bottom of the inner wall of the movable groove 9 .

The clamping block 1010 is adapted to the movable groove 9 so that the clamping block 1010 applies pressure to the limit rod 1009 during the clamping process, thereby sliding on the inner wall of the movable groove 9.

[0031] In a preferred embodiment, the clamping block 1010 is slidably connected to the inner wall of the movable groove 9 via the steel bar 1005 , and the telescopic end of the telescopic block 7 is fixedly assembled with the clamping shell 8 .

[0032] It should be noted that, by fixing the telescopic block 7 to the clamping shell 8, the clamping shell 8 is limited and fixed at the same time.

[0033] In a preferred embodiment, the number of the fixed column 4, the fixed ring 3, the screw rod 5, the moving block 6 and the clamping shell 8 are two, and the two fixed columns 4, the fixed ring 3, the screw rod 5, the moving block 6 and the clamping shell 8 are respectively located on the inner wall of the transport shell 1.

[0034] It should be noted that the two fixing columns 4 , the fixing ring 3 , the screw 5 , the moving block 6 , the clamping shell 8 and the clamping assembly 10 can be used to clamp and fix the instrument from both ends, while also making the device more stable inside the transport shell 1 .

[0035] Working principle: the staff rotates the fixed column 4 by hand, so that the fixed column 4 drives the fixed ring 3 to rotate and drives the screw rod 5 to rotate at the same time, and the outer wall of the screw rod 5 is connected to the moving block 6 through the threaded connection, so that the screw rod 5 rotates the outer wall of the conveying shell 1 and the moving block 6 moves, thereby driving the telescopic block 7 to telescope. After adjusting the required spacing of the equipment, the gravity of the equipment itself is used to press the limit plate 1007, so that the connecting column 1006 and the moving plate 1002 press the spring 1001. When the moving plate 1002 moves, it drives the steel bar 1005 to move downward, and at the same time The clamping block 1010 is driven to clamp inwardly, and at the same time, through the provided limit rod 1009, spring 2 1008 and movable groove 9, the clamping block 1010 will enter the inner wall of the movable groove 9 when clamping inwardly, so that when the limit rod 1009 is pressed, the limit rod 1009 drives the spring 2 1008 to move. When the instrument is taken out of the inner wall of the transport shell 1, the elastic potential energy of spring 1 1001 and spring 2 1008 is released, so that the clamping assembly 10 is restored to its initial state when not clamped, thereby achieving fixed limit of the instrument and easy carrying, and the required spacing of the instrument can also be manually adjusted.
