As shown in fig. 8 and 9, the pusher assembly 13 includes a pusher 131, a pusher 132, a transfer screw 133, and an abutment 134. As shown in fig. 8, the pushing block 131 is provided with an arc-shaped groove, the groove depth is set as a set value, when the pushing block 131 contacts with the inner wall of the sealing ring 20, the movement of the pushing block 131 is blocked, at this time, the height of the anti-rotation pin 30 exposing the inner wall of the sealing ring 20 is just set as a set value, the process of adjusting the exposed height when the anti-rotation pin is manually installed is avoided, and the assembly efficiency of the installation pin is improved. The spherical abutment block 134 is accommodated in the spherical inclined groove of the cone block 12 so that the pusher block assembly 13 does not radially disengage from the cone block 12, and the cone block 12 and the pusher block assembly 13 remain in contact all the time. The push rod 132 is provided with a rectangular limit groove 132A, which is matched with the limit pin 17 to prevent the push block assembly 13 from rotating along the axis thereof.
As shown in fig. 6, the lower end of the driving screw 14 is fixed to the center hole of the base 11 by a stopper ring 16. When the driving screw 14 rotates, the driving cone block 12 moves up and down, and the pushing block assembly 13 is driven to move inwards or outwards in the radial direction.
As shown in fig. 6 and 7, the guide rod 15 is inserted through the mounting hole 111 of the base 11 and the guide rod mounting hole 121 of the cone block 12 to restrict the cone block 12 from rotating.

The driving screw 14 is rotated to drive the cone block 12 to move downwards, so that the three pushing block assemblies 13 are in a contracted state, wherein the contracted state means that the pushing blocks are not contacted with the inner wall of the sealing ring, and a certain distance is reserved between the pushing blocks and the inner wall of the sealing ring 20, so that an anti-rotation pin installation space can be reserved. The anti-rotation pin is pushed into the mounting hole on the sealing ring 20 from the clearance between the pushing block 131 and the inner wall of the sealing ring. The drive screw 14 is then rotated in reverse to drive the cone block 12 upward, and the inclined spherical grooves push the balls radially outward so that the arcuate grooves on the push block 13 contact the inner end surface of the anti-rotation pin 30. The driving screw 14 is continuously rotated to drive the pushing block 131 to squeeze the anti-rotation pin 30, when the pushing block 131 is attached to the inner wall of the sealing ring 20, the movement of the pushing block 131 is blocked, the height of the anti-rotation pin 30 exposed out of the inner wall of the sealing ring is just a set value, and the installation of the anti-rotation pin is completed. And the three pushing blocks of the embodiment synchronously move and simultaneously squeeze the three anti-rotation pins, so that a plurality of anti-rotation pins are installed simultaneously.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same; while the application has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present application or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the application, it is intended to cover the scope of the application as claimed.
