When it is necessary to insert the rocker arm support block 20 into the square mounting groove 11 on the rocker arm 10, the mounting penetration cone 400 can be connected to the rocker arm support block 20 through the protrusion 410 on it first, and then the mounting penetration cone 400 can be connected to the rocker arm support block 20. The upper insertion side is preferentially inserted into the square installation groove 11, so that the rocker arm support block 20 can be driven to gradually approach the square installation groove 11. When the rocker arm support block 20 begins to be inserted into the square installation groove 11, due to the With the guiding action, the rocker arm support block 20 can be accurately aligned with the square installation groove 11. At this time, the rocker arm support block 20 can be gradually pressed into the square installation groove 11 by external force; During the process, the installation penetration cone 400 can still be used for guidance and support, so as to avoid the deflection of the rocker arm support block 20 and damage to the square installation groove 11 . After the rocker arm support block 20 is inserted into the predetermined position in the square mounting groove 11, the mounting penetration cone 400 can be separated from the rocker arm support block 20, and specifically, the mounting penetration cone 400 can be separated from the rocker arm support block by an appropriate external force 20 is separated, so as to realize the recovery of the installation penetrating cone 400, so as to facilitate the application in the installation operation of other rocker arm support blocks 20300.

The installation penetrating cone 400 in this embodiment can be connected to the rocker arm support block 20 in a detachable manner, so that in the process of installing the rocker arm support block 20, the installation penetrating cone 400 can be used to align the rocker arm The support block 20 is guided to avoid the deflection of the rocker arm support block 20 and damage to the square installation groove 11 and the rubber rod 30, and to ensure that the rocker arm support block 20 can be installed accurately and quickly, and the installation of the rocker arm support block 20 is completed. Afterwards, the installation penetrating cone 400 can be separated from the rocker arm support block 20 for recycling.

Wherein, as shown in FIG. 8 , the rocker arm support block 20 may include a main body 22 and a limit plate 21 , one end of the main body 22 is connected to the limit plate 21 , and the length dimension of the limit plate 21 is greater than the radial dimension of the main body 22 . After the rocker arm support block 20 is installed, the limit plate 21 can be blocked with the rocker arm 10 ;

Specifically, the connection hole 23 and the protrusion 410 may be an interference fit. During the installation process, the protrusion 410 can be squeezed into the connection hole 23 by an appropriate external force, so that the rocker arm support block 20 and the installation cone 400 are relatively fixed, so that the rocker arm support block can be driven by the installation cone 400 20 penetrates into the square mounting groove 11, and after the rocker arm support block 20 is inserted, the mounting penetration cone 400 can be separated from the rocker arm support block 20300 by appropriate external force.

Further, as shown in FIG. 4 , the side wall surface of the installation cone 400 includes a first guide surface 420 and a second guide surface 430 , the first guide surface 420 is arranged on the connection side of the installation cone 400 , and the first guide surface 420 is connected to the The center lines of the installation cones 400 are parallel; the second guide surface 430 is an inclined surface, and the second guide surfaces 430 converge toward the insertion side of the installation cone 400 .

The radial dimension at the location of the second guide surface 430 on the installation cone 400 is smaller than or equal to the size of the directional installation groove, that is, the connection side of the installation cone 400 can be transition fit or clearance fit with the square installation groove 11 .

Specifically, during the installation process of the rocker arm support block 20 , the retracted side of the second guide surface 430 can be inserted into the square installation groove 11 first. Smaller, so that it can be quickly inserted into the square installation groove 11, and when the second guide surface 430 begins to enter the square installation groove 11, the second guide surface 430 can cooperate with the inner wall of the square installation groove 11. The posture of the cone 400 is corrected so that the insertion end of the rocker arm support block 20 can be accurately aligned with the square mounting slot 11 , so that the rocker arm support block 20 can be inserted into the square mount slot 11 quickly and accurately.
