When the annular end face of the annular contact head 110 abuts against the other side of the outer ring of the load-bearing bearing 4, until the threaded column 19 can no longer rotate, the clamping and fixing effect of the load-bearing bearing 4 can be achieved. Finally, the shaft body of the external rotating shaft is installed in the inner ring of the load-bearing bearing 4. When the cooling liquid flows inside the annular cooling cavity 15, it will cool the periphery of the load-bearing bearing 4 and the fixed ring body 11.

[0030] For the specific structure of the detachable load-bearing bearing installation mechanism 1, please refer to Figure 3 and Figure 4, including a fixed ring body 11, a fixed base 12 which is integrally structured with the bottom of the fixed ring body 11 and serves as a support is provided, a bearing installation groove 13 is provided in the central area of the fixed ring body 11, a radial limiting hole 14 is provided at one end of the fixed ring body 11 where the bearing installation groove 13 is located, an internal thread installation groove 18 is provided at the other end of the fixed ring body 11 where the bearing installation groove 13 is located, an annular cooling cavity 15 is provided around the bearing installation groove 13 of the fixed ring body 11, a liquid injection channel 16 communicating with the top of the annular cooling cavity 15 is provided in the top area of the fixed ring body 11, a liquid discharge channel 17 communicating with the bottom of the annular cooling cavity 15 is provided at one end of the fixed base 12, a threaded column 19 is installed in the internal thread installation groove 18 of the fixed ring body 11 through a threaded structure, a first shaft body fixing groove 111 with an internal concave structure is provided at one end of the threaded column 19 outside the internal thread installation groove 18, the other end of the threaded column 19 is provided with an annular abutting head 110 which is integrally structured with it and can be inserted into the inside of the bearing installation groove 13, the threaded structure includes an internal thread structure provided in the internal thread installation groove 18 and an external thread structure provided on the outer periphery of the column body of the threaded column 19, and the internal thread structure matches the external thread structure, the structural radius of the radial limiting hole 14 is the same as the structural radius of the inner ring hole of the annular abutting head 110, and the wall thickness of the annular abutting head 110 is not greater than the wall thickness of the outer ring of the load-bearing bearing 4.

[0031] In order to enable the coolant to efficiently cool the equipment in a way that fills the annular cooling cavity 15, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , it is necessary to set up a cache-type liquid flow control mechanism 2, which internally has a horizontal hollow outer shell 21 fixedly installed on one side of the fixed ring body 11 and in a hollow state inside, and an annular elastic air film 26 embedded inside the horizontal hollow outer shell 21 and capable of restricting the flow of the liquid flowing out of the fixed ring body 11. Using an inflation device to inflate the inside of the gas injection channel 25, under the action of air pressure, the annular elastic air film 26 will have a phenomenon of inner diameter closing. It is necessary to make the central aperture of the annular elastic air film 26 smaller than the central apertures of the liquid injection channel 16 and the liquid discharge channel 17. At this time, when the cooling liquid enters the inner diameter of the annular elastic air film 26 from the liquid discharge channel 17, it is best to make the inner diameter zero, which will hinder the flow of the liquid. At this time, the liquid can fill the annular cooling cavity 15. When the pressure of the cooling liquid is greater than the elastic strength of the annular elastic air film 26, it will flow outwards through the inner diameter of the annular elastic air film 26, so that the coolant can efficiently cool the equipment in a way that fills the annular cooling cavity 15.

[0032] For the specific structure of the buffer type liquid flow control mechanism 2, please refer to Figure 5 and Figure 6 , including a horizontal hollow shell 21, a gas storage chamber 22 is arranged inside the horizontal hollow shell 21, a docking channel 23 which is an integral structure with the horizontal hollow shell 21 and fixedly docked with the liquid discharge channel 17 is arranged at one end of the horizontal hollow shell 21, a docking channel 24 which is connected to the gas storage chamber 22 is arranged at the other end of the horizontal hollow shell 21, an annular embedding groove 27 with an inner concave structure is arranged at both ends of the gas storage chamber 22, an annular elastic gas membrane 26 is embedded in an edge-sealed manner between the two annular embedding grooves 27, and a gas injection channel 25 which is connected to the outer circumferential surface of the gas storage chamber 22 and has an air valve installed inside is arranged on the outer circumferential surface of the horizontal hollow shell 21.

[0033] To achieve torque-controlled thread tightening, see Figure 1 , Figure 2 , Figure 7 and Figure 8 , it is necessary to set up a force-controllable linkage mechanism 3, which is internally provided with a hollow disk body 31 that can rotate with the wrench, an inner rotating column 310 that can drive the threaded column 19 to rotate, and an arc-shaped contact plate 39 that relies on friction to enable the hollow disk body 31 and the inner rotating column 310 to link. Using a wrench, applying a rotation effect to the hexagonal wrench head 32 will cause the No. 1 rotating shaft 312 to drive the threaded column 19 to rotate. When the annular end face of the annular contact head 110 contacts the other side of the outer ring of the load-bearing bearing 4, until the threaded column 19 can no longer rotate, when the torque resistance is greater than the force formed by the maximum static friction between the inner rotating column 310 and the arc-shaped contact plate 39, relative rotation occurs between the hollow disk body 31 and the arc-shaped contact plate 39, and the torque resistance will not continue to increase, thereby achieving the maximum tightening force of the threaded column 19 and realizing a torque-controllable thread tightening effect.

[0034] For the specific structure of the force controllable linkage mechanism 3, please refer to Figure 7 and Figure 8, including a hollow disk body 31 and an inner rotating column 310, one end surface of the hollow disk body 31 is provided with a hexagonal wrench head 32 of an integral structure therewith, a columnar component mounting cavity 33 is provided in the center of the hollow disk body 31, a shaft mounting hole 34 is provided in the center of one end of the hollow disk body 31, the shaft body of the No. 1 rotating shaft 42 is installed in the shaft mounting hole 34 through a bearing, an inner rotating column 310 is placed in the center of the columnar component mounting cavity 33, a No. 2 shaft fixing groove 311 for installing the No. 1 rotating shaft 312 is provided in the center of one end of the inner rotating column 310, one end of the No. 1 rotating shaft 312 is fixedly installed in the No. 1 shaft fixing groove 111, and a plurality of annular array-type longitudinal component active cavities 35 are provided on the periphery of the columnar component mounting cavity 33 of the hollow disk body 31, and the longitudinal component active cavity 35 and the columnar component mounting cavity The circumferential side surfaces of 33 are connected through a No. 1 shaft body through hole 36, and an inner movable plate 37 capable of axially moving along the cylindrical component mounting cavity 33 is disposed inside the hollow disk body 31 located in the cylindrical component mounting cavity 33, and a No. 1 coil spring 38 is disposed at one end of the inner movable plate 37, and a connecting shaft body penetrating the No. 1 shaft body through hole 36 is fixedly mounted on the other end of the inner movable plate 37, and an arc-shaped contact plate 39 that abuts against the circumferential surface of the inner rotating column 310 is fixedly mounted on one end of the connecting shaft body located in the cylindrical component mounting cavity 33, one end of the No. 1 coil spring 38 abuts against one end surface of the inner movable plate 37, and the other end abuts against one end surface of the longitudinal component movable cavity 35, and the No. 1 coil spring 38 is in a compressed state, and the structural radius of the inner concave surface of the arc-shaped contact plate 39 matches the structural radius of the inner rotating column 310.

[0035] In use, a wrench is used to apply a rotational effect to the hexagonal wrench head 32, which will cause the first rotating shaft 312 to drive the threaded column 19 to rotate. The load-bearing bearing 4 is installed inside the bearing installation groove 13, and one end of the outer ring of the load-bearing bearing 4 abuts against the corresponding annular end face of the radial limiting hole 14. Then, the threaded column 19 is screwed into the internal thread installation groove 18. When the annular end face of the annular abutting head 110 abuts against the other side of the outer ring of the load-bearing bearing 4, until the threaded column 19 can no longer rotate, the liquid discharge circuit and the liquid inlet circuit of the water-cooling device are respectively connected to the liquid injection channel 16 and the second docking channel 24 through pipes. An inflation device is used to inflate the inside of the gas injection channel 25. Under the action of air pressure, the inner diameter of the annular elastic air film 26 will shrink. It is necessary to make the central aperture of the annular elastic air film 26 smaller than the central apertures of the liquid injection channel 16 and the liquid discharge channel 17. At this time, when the cooling liquid enters the inner diameter of the annular elastic air film 26 from the liquid discharge channel 17, it is best to make the inner diameter zero, which will hinder the flow of the liquid. At this time, the liquid can fill the annular cooling cavity 15. When the pressure of the cooling liquid is greater than the elastic strength of the annular elastic air film 26, it will flow outwards through the inner diameter of the annular elastic air film 26, so that the cooling liquid can efficiently cool the device in a way that fills the annular cooling cavity 15.
