[0033] In combination Figure 8 As shown in the figure, in the utility model, in order to install bearing 102 in support hole 1011 of support 101, first, bearing 102 is placed on support hole 1011, which is not embedded in support hole 1011 initially, lifting unit 20 drives pressure head 40 to move downward and abut with bearing 102, and bearing 102 is pressed and installed in support hole 1011 by pressing, and the lower end of bearing 102 abuts on limiting ring 1012, completing the installation of bearing 102 on support 101.

[0034] In addition, if bearing 102 is directly placed on support hole 1011, it is not conducive to the accurate positioning of bearing 102, pressure head 40 can also be selected to have magnetic properties, or a component that can be magnetically attracted is arranged on pressure head 40, so that bearing 102 can be attracted to pressure head 40, and bearing 102 is driven to move downward and press into support hole 1011 during the downward movement of pressure head 40.
