[0048] Further, the two first mounting slots 5 are arranged on the inner walls of the rotating groove 4.

[0049] The first mounting slot 5 is communicated with the second mounting slot 6.

[0050] The mounting barrel 3 is fixedly connected between the inner walls of the two first mounting slots 5.

[0051] The bidirectional screw 14 is arranged on the outer surface of the mounting barrel 3.

[0052] Further, the mounting barrel 3 is communicated with the second mounting slot 6, and the two rotating rings 7 are threadedly sleeved on the outer surface of the mounting barrel 3 through the bidirectional screw 14.

[0053] The two rotating rings 7 are located at the opposite threads of the bidirectional screw 14.

[0054] The plurality of connecting rods 9 are fixedly connected to the outer surfaces of the two rotating rings 7.

[0055] Further, the two pushing rings 11 are fixedly connected to the two ends of the connecting rods 9.

[0056] The pushing ring 11 is sleeved on the mounting barrel 3.

[0057] The two friction pads 8 are fixedly connected to the outer surfaces of the two rotating rings 7.

[0058] The plurality of connecting slots 12 are arranged on the outer surface of the mounting barrel 3, and the four connecting slots 12 are located in the corresponding first mounting slots 5.

[0059] Further, the corresponding connecting slots 12 are arranged in a central array with the mounting barrel 3 as the center.

[0060] The two fixed blocks 13 are fixedly connected to the outer surface of the mounting barrel 3.

[0061] The plurality of fixed rods 19 are rotatably connected between the corresponding two fixed blocks 13.

[0062] The plurality of connecting blocks 15 are fixedly connected to the outer surfaces of the corresponding fixed rods 19.

[0063] Further, the plurality of triangular blocks 16 are fixedly connected to the corresponding connecting blocks 15.

[0064] Among them, the vertical cross section of the triangular block 16 is triangular in shape, and the outer surface of the side of the triangular block 16 away from the mounting cylinder 3 is an inclined arc surface;

[0065] Multiple mounting holes 10 are formed on the upper surface of the base 1, and the mounting holes 10 extend out of the lower surface of the base 1.

[0066] Furthermore, multiple rubber blocks 17 are respectively fixedly connected to the outer surface of the corresponding triangular block 16 near the mounting cylinder 3.

[0067] Among them, multiple positioning tension springs 18 are respectively fixedly connected to the outer surface of the corresponding connecting block 15 on the side away from the mounting cylinder 3;

[0068] The end of the positioning tension spring 18 away from the connecting block 15 is fixedly connected to the inner wall of the corresponding first mounting groove 5.

[0069] Furthermore, in the initial state, the push ring 11 is located outside the first mounting groove 5, and in the initial state, the positioning tension spring 18 supports and positions the connecting block 15, the triangular block 16 and the rubber block 17, so that the rubber block 17 remains stable in the connecting groove 12, and prevents the rubber block 17 from moving into the mounting cylinder 3 when the triangular block 16 is not subjected to external force.

[0070] In use, the linear bearing is passed through the second mounting groove 6 and the mounting cylinder 3. Then, the two rotating rings 7 are rotated, causing them to move in opposite directions. This synchronously drives the connecting rods 9 and the pushing ring 11 on both sides to move in opposite directions. During this movement, the pushing ring 11 moves into the corresponding first mounting groove 5, and during this movement, it contacts the inclined arc surface of the triangular block 16. As the pushing ring 11 rotates, it applies a pushing force to the inclined arc surface of the triangular block 16, causing the triangular block 16 to rotate around the fixed rod 19. This process also provides a positioning pull... The spring 18 is stretched, causing the positioning spring 18 to deform. During this process, the rubber block 17 is also driven to extend into the mounting cylinder 3 through the connecting groove 12 and contact the outer surface of the linear bearing. As the pushing ring 11 pushes the triangular block 16, the rubber block 17 is driven to squeeze the outer surface of the linear bearing. In this way, multiple rubber blocks 17 clamp and fix the linear bearing, thereby achieving the fixed installation of the linear bearing. The installation is convenient and quick, which facilitates the installation and maintenance of the support bearing. Only two rotating rings 7 need to be rotated, thereby improving the practicality of the support bearing fixing seat.

[0071] As described above, during disassembly, only the two rotating rings 7 need to be rotated to move relative to each other. During this process, the two pushing rings 11 are moved out of the two first mounting slots 5. As the two pushing rings 11 move out of the first mounting slots 5, they do not contact the corresponding triangular blocks 16. Under the release force of the corresponding positioning tension springs 18, the connecting block 15, triangular blocks 16 and rubber blocks 17 are reset, and the rubber blocks 17 are moved out of the mounting cylinder 3. This prevents the rubber blocks 17 from contacting the outer surface of the linear bearing, thus realizing the disassembly of the linear bearing from the fixed seat. The disassembly is convenient, flexible and efficient, and simple, which facilitates the maintenance of the linear bearing and increases the practicality and flexibility of the fixed seat for the linear bearing.

[0075] Fixing block 13: used for supporting and positioning the fixing rod 19;

[0076] Fixed rod 19: It is the rotation center of connecting block 15, triangular block 16 and rubber block 17. During the process of pushing triangular block 16 by pushing ring 11, connecting block 15, triangular block 16 and rubber block 17 rotate around fixed rod 19.

[0077] Friction pad 8: Friction pad 8 is used to increase the friction on the outer surface of the rotating ring 7, thereby facilitating the rotation of the rotating ring 7 and preventing slippage when rotating the rotating ring 7;

[0078] Connecting groove 12: The rubber block 17 extends into the mounting cylinder 3 through the connecting groove 12, thereby clamping the outer surface of the support bearing;
