[0028] Next, specifically describe the specific settings and functions of its mobile device 5 and connecting device 6.

[0029] Referring to Figure 2 And Figure 3As shown, in this embodiment: The mobile device 5 includes a plurality of card slots 51 and a first spring 57. The plurality of card slots 51 are evenly opened on the surface of the support frame 1. A clamping block 52 is slidably connected to the inner wall of the card slot 51. On one side of the two clamping blocks 52 close to each other, a sliding tube 53 is fixedly connected. A same fixing column 54 is slidably connected to the inner walls of the two sliding tubes 53. The sliding tube 53 and the fixing column 54 are made of stainless steel. A connecting column 3 is fixedly connected to the arc surface of the fixing column 54. On the arc surface of one end of the two sliding tubes 53 close to each other, a pressing plate 55 is fixedly connected. The two ends of the first spring 57 are respectively fixedly connected to one side of the two pressing plates 55 close to each other. By providing the mobile device 5 and operating the cooperation between the plurality of clamping blocks 52 and the card slots 51, the clamping block can be adjusted to multiple different positions and fixed. A telescopic rod 58 is slidably connected to the inner wall of the first spring 57. The two ends of the telescopic rod 58 are respectively fixedly connected to one side of the two pressing plates 55 close to each other, preventing the first spring 57 from bending and affecting normal use. An auxiliary plate 56 is fixedly connected to the surface of the pressing plate 55. The auxiliary plate 56 is an elastic rubber plate. The effects achieved by the above components are: increasing the friction between the hand and the pressing plate 55, facilitating the movement of the pressing plate 55. A limiting rod 59 is fixedly connected to the upper surface of one end of the card slot 51 close to the fixing column 54. The cross section of the limiting rod 59 is rectangular, playing a limiting role on the clamping block 52 to prevent the clamping block 52 from sliding out of the card slot 51 and making it inconvenient to slide the clamping block 52.

[0030] Referring to Figure 4 As shown, in this embodiment: The connecting device 6 includes a connecting pipe 67 and a second spring 68. One end of the inner wall of the connecting pipe 67 is fixedly connected to the arc surface of the fixing column 54. A fixing frame 61 is fixedly connected to the arc surface of the connecting pipe 67. The cross section of the fixing frame 61 is in a "U" shape. A sliding column 62 is slidably penetrated through the inner wall of the fixing frame 61. The two ends of the second spring 68 are respectively fixedly connected to the sliding column 62 and the fixing frame 61. The arc surface of the connecting pipe 67 is slidably penetrated by the sliding column 62. A clamping rod 4 is slidably connected to the inner wall of the connecting pipe 67. A sliding groove 64 is opened at the position of the arc surface of the clamping rod 4 corresponding to the sliding column 62. The size of the sliding groove 64 is adapted to the size of the sliding column 62. By providing the connecting device 6, the user can quickly use the connecting device 6 by pulling the pull ring 63, with simple operation and convenient use. One end of the sliding column 62 is fixedly connected to a pull ring 63. The cross section of the pull ring 63 is circular ring-shaped, facilitating the pulling of the sliding column 62. A positioning rod 65 is fixedly connected to the arc surface of the clamping rod 4. A limiting groove 66 is opened at the position of the inner wall of the connecting pipe 67 corresponding to the positioning rod 65. The size of the limiting groove 66 is adapted to the size of the positioning rod 65. The cooperation between the positioning rod 65 and the limiting groove 66 plays a rotational limiting role on the clamping rod 4, facilitating the alignment of the sliding groove 64 with the position of the sliding column 62.

[0031] The working principle of a bearing disassembly device for maintenance provided by the present utility model is as follows. When it is necessary to disassemble a bearing, first adjust the position of the clamping rod 4 according to the size of the bearing housing. First, adjust the distance between the two clamping rods 4. First, squeeze the two pressure plates 55. The pressure plates 55 drive the two sliding tubes 53 to slide along the fixed column 54 in the direction of approaching each other. In this process, the first spring 57 is in a compressed state. When the clamping block 52 slides out of the clamping groove 51, move the pressure plate 55 to drive the clamping rod 4 to contact the bearing. Then release the pressure plate 55. At this time, under the action of the first spring 57, the two clamping blocks 52 are ejected into the clamping groove 51, realizing the fixing effect on the clamping rod 4. Then, after adjusting another moving device 5 to the same position, rotate the screw rod 2 to take out the bearing.

[0032] When the clamping rod 4 is used for a long time, the clamping rod 4 is likely to slip after getting stained with oil when contacting the bearing. It is necessary to take it out in time for replacement or cleaning. First, pull the pull ring 63. The pull ring 63 drives the sliding column 62 to slide out of the sliding groove 64. In this process, the second spring 68 is in a stretched state, releasing the fixing effect on the clamping rod 4. Then replace the clamping rod 4 with a new one. Align the positioning rod 65 with the limiting groove 66 and slide it to the bottom. Release the pull ring 63. At this time, under the action of the contraction of the second spring 68, the sliding column 62 is pulled into the sliding groove 64, realizing the fixing effect on the clamping rod 4.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
