[0025] The outer part of the lubricating roller 51 is uniformly provided with bristles, and the lubricating roller 51 is in sliding contact with the stamping head group 4. The bristles can increase the amount of lubricating oil on the outer part of the lubricating roller 51, thereby improving the lubricating effect on the stamping head group 4. The horizontal shaft 53 can support the lubricating roller 51 and drive the lubricating roller 51 to rotate through the gear 54. The gear 54 can rotate by engaging with the rack 52. The connecting rod 55 can drive the lubricating roller 51 to move. The cooperation of the return arm 56 and the spring 57 can make the lubricating roller 51 return after moving.
