[0040] Then, when the knuckle is placed, the bearing can be placed on the surface of the knuckle, and then the pressing strip 504 on the two connecting plates 404 is pressed, the pressing strip 504 slides downward to drive the connecting rod 505 and the connecting strip 507 to slide downward, the fourth spring 506 is compressed, the connecting strip 507 slides downward to drive the clamping block 508 to no longer engage the clamping groove 509 on the sliding strip 406, at this time the sliding strip 406 will drive the positioning block 407 to clamp the top end of the bearing under the reset action of the third spring 409, thereby positioning the bearing to prevent it from deviating during the pressing process, then the pressure arm 2 is started, which will press the bearing and the positioning block 407, the setting of the guide strip 408 avoids the deviation of the third spring 409 and makes the sliding of the sliding strip 406 more stable, the positioning block 407 and the bearing will slowly press into the interior of the knuckle during the descending process, the sliding strip 406 will descend with the positioning block 407, the sliding strip 406 will descend with the connecting plate 404, the connecting plate 404 will descend with the sliding block 401 in the interior of the supporting rod 304, the second spring 403 is compressed, the setting of the first guide column 402 and the second guide column 405 improves the stability of the connecting plate 404 during the descending process, and the first guide column 402 makes the compression of the second spring 403 more stable to prevent it from deviating, the connecting plate 404 will descend with the driving strip 501, the driving strip 501 will descend with the roller 502, the roller 502 will be in contact with the triangular driving block 503, and continuing to press the bearing and the positioning block 407 will make the roller 502 roll on the inclined surface of the driving block 503, thereby driving the driving strip 501 to slide horizontally, the two driving strips 501 will slide away from each other, which will make the two sliding strips 406 slide away from each other, the sliding strip 406 will be in contact with the trapezoidal clamping block 508 on the connecting plate 404, the clamping block 508 will drive the connecting strip 507 and the connecting rod 505 to descend, the fourth spring 506 is compressed, until the clamping groove 509 slides above the clamping block 508, at this time the pressing strip 504 and the clamping block 508 will reset under the reset action of the fourth spring 506, thereby making the clamping block 508 and the sliding strip 406 reengage, when the clamping block 508 and the sliding strip 406 are completely engaged, the positioning block 407 just disengages from the bottom end of the pad 603, at this time the pad 603 no longer exerts pressure on the positioning block 407 and no longer blocks the positioning block 407, but only continues to press the bearing, because the bearing has entered a large part of the interior of the knuckle at this time, so it is not necessary to continue to position the bearing, and the positioning block 407 will reset the connecting plate 404, the sliding strip 406 and the positioning block 407 under the reset action of the second spring 403 after losing the pressure of the pad 603, back to the initial height and initial state, waiting for the bearing to be installed, then the knuckle is taken out;

[0041] Finally, before the bearing is pressed down using the pressure arm 2, the spacer 603 is in contact with the bearing and the positioning block 407, the handle 703 on the rotating installation strip 701 is turned, which drives the screw rod 702 to rotate and in turn drives the contact of the resistance strip 704 with the resistance block 604 on the pressure rod 602. At this time, the mark 706 on the resistance strip 704 is observed on the scale 707 on the installation strip 701. Then, the rotating handle 703 is turned to drive the resistance strip 704 to descend by one bearing height minus the circular arc radius length of one resistance block 604. The arrangement of the guide shaft 705 improves the sliding stability of the resistance strip 704 and the stability after being stressed. Then, the rocker on the pressure arm 2 is pressed by hand, which makes the telescopic end of the pressure arm 2 continuously lengthen, in turn driving the connecting shaft 601 to descend and the pressure rod 602 on the connecting shaft 601 to descend. The pressure rod 602 makes the spacer 603 descend, driving the spacer 603 to press down the bearing and the positioning block 407. The pressure rod 602 continuously descends until the bearing is completely installed into the knuckle at the last resistance block 604 circular arc portion radius length. The resistance strip 704 will be in contact with the resistance block 604. Continue to lower the pressure rod 602, and the resistance block 604 will slowly shrink into the interior of the pressure rod 602, while the resistance block 604 will be in contact with the limiting block 606 and no longer engage the limiting slot 607 on the pressure rod 602. At this time, the continuous telescoping of the pressure arm 2 will cause the connecting shaft 601 and the pressure rod 602 to slide. The connecting shaft 601 will slide in the cavity of the pressure rod 602. Continue to pressurize, which will not generate pressure on the pressure rod 602 and the spacer 603, and in turn will not continue to press down the bearing. When the pressure relief assembly on the pressure arm 2 works, the telescopic end of the pressure arm 2 will rise, in turn driving the connecting shaft 601 to rise. At this time, since the limiting block 606 has a trapezoidal cross section, when it is at the trapezoidal structure at the top of the cavity in the pressure rod 602, the rising will make the limiting block 606 shrink into the interior of the connecting shaft 601 (the gravity of the spacer 603 and the pressure rod 602 is enough to make the connecting shaft 601 and the pressure rod 602 slide), the sixth spring 608 is compressed, until the limiting block 606 reaches the position of the limiting slot 607. At this time, since the bottom end of the connecting shaft 601 is a T-shaped structure, it is in contact with the upper wall of the cavity in the pressure rod 602. The limiting block 606 is still in contact due to the resistance of the resistance strip 704 outside the pressure rod 602, so it will always shrink in the connecting shaft 601. However, continue to shrink the telescopic end of the pressure arm 2, the connecting shaft 601 rises, since the bottom end has been in contact with the upper wall of the cavity in the pressure rod 602, it will drive the pressure rod 602 to rise. The rising of the pressure rod 602 will make the resistance strip 704 no longer in contact with the resistance block 604. Under the resetting action of the fifth spring 605 and the sixth spring 608, the resistance block 604 is reset, and the limiting block 606 is engaged into the limiting slot 607 in the pressure rod 602, so that the connecting shaft 601 can continue to generate pressure on the pressure rod 602 when it is pressed down next time.
