The lower fixed block is configured to guide the shaft pin so as to ensure the perpendicularity of the shaft pin after press-assembling.
Preferably,a magnet is provided on the pressing rod or the fixed block, and the shaft pin is fixed on a lower end face of the pressing rod by the magnetic force of the magnet.
The present invention has the advantages that it is convenient to assemble the shaft pin by pressing and can ensure the press-assembling position of the shaft pin.

A positioning pin holding groove 31, which runs through the lower pad 3 from the top down, is formed on the lower pad 3, and a positioning pin 5 and a first compression spring 32 are provided in the positioning pin holding groove 31. The positioning pin 5 consists of a positioning pin positioning portion 51 and a positioning pin fixing portion 52 located on a lower side of the positioning pin positioning portion 51, and the outer diameter of the positioning pin fixing portion 52 is greater than that of the positioning pin positioning portion 51. A lower end of the first compression spring 32 is resisted against the soleplate 1 and an upper end of the first compression spring 32 is resisted against a lower end face of the positioning pin fixing portion 52. A lower evading groove 41 which is located in an upper portion of the lower fixed block body 4 and a positioning pin evading groove 42 which is communicated with the lower evading groove 41 are formed on the lower fixed block body 4, the inner diameter of the positioning pin evading groove 42 is less than the outer diameter of the positioning pin fixing portion 52, and the positioning pin positioning portion 51 is always located in the positioning pin evading groove 42 under the action of the first compression spring 32. The lower evading groove 41 is configured to evade and fix a shaft 12. 3 2017100855 26 Jun2017 A fitting groove, which runs through the bracket from the top down, is formed on the bracket 2. A pressing rod 9, having a shaft pin 8 fixed at a lower end thereof, is provided in the fitting groove, and the pressing rod 9 and the positioning pin 5 are arranged coaxially. A second compression spring 91 is sleeved on the pressing rod 9. When a force is applied to the pressing rod 9 to drive the shaft pin 8 to move downward, the pressing rod 9 moves upward to the original position under the action of the second compression spring 91. A pressing block 92 is fixed at an upper end of the pressing rod, and the second compression spring 91 is located on an upper side of the bracket 2 and confined between a lower end face of the pressing block 92 and an upper end face of the bracket 2. The pressing block 92 is fixed to the upper end of the pressing rod 9 by threads, and a threaded hole, which runs through from the top down to fit the upper end of the pressing rod 9, is formed on the pressing block 92.
An upper fixed block fixed to the bracket 2 is provided on an upper side of the lower fixed block, and the lower fixed block consists of an upper fixed block body 6 and an upper pad 7 located on an upper side of the upper fixed block body 6. A shaft pin fitting groove 61, through which only the shaft pin 8 passes, is formed on the upper fixed block body 6 and runs through the upper fixed block body 6 from the top down, the inner diameter of the shaft pin fitting groove 61 is less than the outer diameter of a lower end of the pressing rod 9, and the shaft pin fitting groove 61 and the positioning pin 5 are arranged coaxially. A pressing rod boss 93 which extends radially and outward is formed on the pressing rod 9 and located on a lower side of the bracket 2.
