The kingpin fixing seat 2 is installed on the top front side of the base 1, and two positioning columns 21 are provided on the kingpin fixing seat 2. The U-shaped pressure block 6 is installed on the top of the kingpin fixing seat 2 and is located between the two positioning columns 21. The two positioning columns 21 pass through the positioning holes at both ends of the kingpin 9 respectively, and the U-shaped pressure block 6 presses both sides of the kingpin 9. An upper support block 5 is installed on the top rear side of the base 1, and a slide rail 4 is installed on the vertical surface of the upper support block 5. The rear side of the slider 3 is slidably connected to the slide rail 4, and the slider 3 is located above the kingpin fixing seat 2, and the fork mounting block 8 is fixed to the lower part of the slider 3. The upper end of the fork 10 is installed in the mounting groove of the fork mounting block 8, and the lower end of the fork 10 passes through the notch of the U-shaped pressure block 6 and is connected to the kingpin 9.

[0023] A pad 7 is installed on one side of the kingpin fixing seat 2 close to the upper support block 5. The pad 7 contacts or separates from the bottom of the slider 3. During the pressing process of the press, the pad 7 serves as a stop for the sliding stroke of the slider 3.
