When the rack 17 moves to the specified position, the rack 17 will continue to mesh with the gear 9 on the left, thereby pre-fixing the base 1, the controller body 2 and the adapter 3, and the inner top of the controller body 2 is fixedly connected with multiple L-shaped rods 12, and multiple threaded sleeves 11 are provided with guide grooves, and each L-shaped rod 12 is slidably connected to the inner wall of the corresponding guide groove.

The fastening assembly includes a circular cavity arranged in the rotating shaft 5, a piston 33 is sealingly and slidably connected in the circular cavity, a rotating rod 29 is rotatably connected to the inner bottom of the circular cavity, the lower end of the rotating rod 29 extends to the outside and is fixedly connected to the knob 23, a threaded layer is arranged on the rotating rod 29, a moving block 34 is threadedly connected to the threaded layer part of the rotating rod 29, and the moving block 34 and the adjacent side of the piston 33 are fixedly connected to a connecting rod 35, a rectangular cavity 14 is arranged in the controller body 2 and the adapter 3, the two rectangular cavities 14 are connected to a connecting pipe 15, two insertion holes 22 are arranged in the top space of the circular cavity, the top space of the circular cavity is filled with magnetorheological fluid, and there is no external It exhibits low-viscosity Newtonian fluid characteristics when in a magnetic field, and exhibits high-viscosity, low-fluidity Bingham fluid when an external magnetic field is applied. There is a corresponding relationship between the viscosity of the liquid and the magnetic flux. A guide rod is fixedly connected to the inner bottom of the circular cavity, and the guide rod passes through the moving block 34. The top space of the circular cavity is connected to the outside through an air hole, and a sealing plug 6 is provided on the air hole. During installation, the knob 23 can be controlled to rotate clockwise to inject the magnetorheological fluid into the two rectangular cavities 14, and then the magnetic block 7 is installed and the air hole is opened. At this time, the magnetorheological fluid becomes a high-viscosity fluid. When the moving block 34 moves downward, a gap is generated between the magnetorheological fluid and the inner wall of the circular cavity. At this time, the air flow will enter the circular cavity through the gap.

Among them, the inner top of the circular cavity is fixedly connected with a vertical plate 28, and the left and right sides of the vertical plate 28 are fixedly connected with telescopic rods 31. The telescopic ends of the two telescopic rods 31 are fixedly connected with sealing plugs 32. The two sealing plugs 32 are elastically connected to the adjacent sides of the corresponding vertical plates 28 through springs 30. The opposite sides of the two sealing plugs 32 are fixedly connected with push rods 36, so that when the controller body 2 is not installed, the magnetorheological fluid will not be retained to the outside, and the push rods 36 will contact the tube wall of the connecting tube 15 after installation, so that the sealing plug 32 moves in the direction close to the vertical plate 28, thereby connecting the circular cavity with the rectangular cavity 14.

Among them, the outer side of the base 1 is provided with a plurality of embedding grooves 27, and a plurality of embedding grooves 27 are provided with magnetic blocks 7, each magnetic block 7 is provided with a rectangular hole 18, and the inner bottom of each embedding groove 27 is provided with a movable groove, and a rectangular block 19 is slidably connected in each movable groove, and the lower end of each rectangular block 19 is provided with a threaded hole, and a threaded rod 26 is threadedly connected in each threaded hole, and each threaded rod 26 is rotatably connected to the inner bottom of the movable groove, and the lower end of each threaded rod 26 extends to the outside, and the plurality of threaded rods 26 are connected by the second transmission assembly 25, and the threaded rod 26 on the left side is connected by the first transmission assembly 24, and the plurality of threaded rods 26 are distributed in a ring array, and the first transmission assembly 24 includes a first sprocket arranged on the rotating rod 29 and the threaded rod 26, and the two first sprockets are connected by a first chain transmission, and the second transmission assembly 25 includes a second sprocket arranged on three threaded rods 26, and the three second sprockets are connected by a second chain transmission.

A circuit board and a heat sink are installed in the controller body 2 . A plurality of heat dissipation holes are arranged on the inner top of the controller body 2 to facilitate heat dissipation. Two wiring holes 4 are installed on the adapter 3 .

The functional principle of the present invention can be explained by the following operation mode: first, align the slide groove 8 on the controller body 2 with the two guide blocks 20, then push the controller body 2 to make the controller body 2 move right, so that the guide block 20 enters the slide groove 8, so that the multiple through holes 13 are aligned with the corresponding limit holes 21, and then align the two racks 17 on the adapter 3 with the two gears 9, and push the adapter 3 to move left, so that the adapter 3 and the controller body 2 are combined;

When the adapter 3 enters the controller body 2, the two racks 17 will first mesh with the two gears 9 on the right side, so that the two gears 9 on the front side drive the corresponding screw rods 10 to rotate, thereby causing the threaded sleeve 11 to move downward (because the L-shaped rod 12 is slidably connected to the guide groove, the threaded sleeve 11 will not rotate when the screw rod 10 rotates, so that the threaded sleeve 11 moves downward). After the threaded sleeve 11 moves downward, it will enter the limiting hole 21 through the through hole 13;

As the adapter 3 continues to move to the left, the rack 17 is no longer meshed with the gear 9 on the right, and then the rack 17 is meshed with the two gears 9 on the left, so that the screw rod 10 on the left rotates, so that the threaded sleeve 11 on the left moves down and enters the limiting hole 21. Since the adapter 3 is in contact with the controller body 2, the rack 17 is still in meshing with the two gears 9 on the left, so that the base 1, the controller body 2 and the adapter 3 are in a preliminary fixed state;

After the controller body 2 and the adapter 3 are initially fixed, the two connecting tubes 15 are inserted into the insertion hole 22. When the connecting tube 15 is inserted into the insertion hole 22, the stopper 36 and the sealing plug 32 are moved toward the vertical plate 28 through the stopper 36, so that the spring 30 is in a compressed state. At this time, the circular cavity is connected to the two rectangular cavities 14.

Since the space above the circular cavity is filled with magnetorheological fluid, the staff can rotate the knob 23 clockwise, so that the rotating rod 29 rotates clockwise, and then the moving block 34 drives the piston 33 to move upward, so that the bottom space of the circular cavity is reduced and the air pressure is increased, so that the magnetorheological fluid enters the rectangular cavity 14 through the two connecting pipes 15, and the air in the rectangular cavity 14 is squeezed to the outside;

When the moving block 34 moves to the extreme position, most of the magnetorheological fluid enters the two rectangular cavities 14, and a small amount of magnetorheological fluid remains in the circular cavity. At this time, the staff can embed the three magnetic blocks 7 into the embedding groove 27 (when the knob 23 is rotated clockwise, the three threaded rods 26 are driven to rotate by the first transmission component 24 and the second transmission component 25, so that the three rectangular blocks 19 move down to the moving groove). After the three magnetic blocks 7 are embedded in the embedding groove 27, a magnetic field will be generated around the base 1. At this time, the magnetorheological fluid will present a Bingham fluid with high viscosity and low fluidity, thereby fixing the controller body 1, the adapter 3 and the rotating shaft 5 together;

At this time, the staff can open the sealing plug 6 to connect the air hole with the outside, and then the staff can turn the knob 23 counterclockwise to make the rotating rod 29 rotate counterclockwise, so that the rotating rod 29 drives the three threaded rods 26 to rotate counterclockwise, so that the three rectangular blocks 19 are moved up to the rectangular holes 18, thereby fixing the three magnetic blocks 7;

It is worth mentioning that after the magnetic field is formed around the magnetorheological fluid, the magnetorheological fluid will not flow easily and will present a solid-like shape. At this time, when the knob 23 is rotated counterclockwise, the moving block 34 will move downward, and the magnetorheological fluid in the rectangular cavity 14 will not re-enter the circular cavity. At this time, the external gas will enter the circular cavity through the gap between the magnetorheological fluid and the circular cavity, and the moving block 34 and the piston 33 will move downward;

When the controller needs to be disassembled, the staff can turn the knob 23 clockwise to move the movable block 34 and the piston 33 upward, thereby pressing the gas in the circular cavity out to the outside through the pores. At this time, the three threaded rods 26 rotate clockwise to move the three rectangular blocks 19 downward, contacting the restriction on the magnetic block 7. The staff can remove the three magnetic blocks 7 to release the magnetic field around the magnetorheological fluid, turning the magnetorheological fluid into a low-viscosity fluid. Then the staff can use the sealing plug 6 to block the pores, and then control the knob 23 to rotate counterclockwise, so that the magnetorheological fluid in the two rectangular cavities 14 enters the circular cavity. At this time, the staff only needs to remove the adapter 3 and the controller body 2 in turn.

The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
