[0002] The center is an auxiliary tool commonly used in lathe processing shaft parts. It is set at the end away from the chuck and is used to push against the end of the shaft part away from the chuck. Therefore, a center structure for lathe processing metal parts is needed.

[0003] According to the description of a lathe center disclosed in the patent website (authorization announcement number: CN 219025953 U), "the utility model provides an adjustable center for a lathe, involving the field of center technology, including: a seat body and an adjustment part; a center is slidably connected to the seat body; a sliding protrusion is welded to the left end face and the right end face of the outer wall of the center, and the two sliding protrusions are slidably connected to the two sliding grooves respectively, and the sliding protrusion and the sliding groove together constitute the axial limiting structure of the center; because an elastic block is sleeved on the threaded rod, the upper end of the elastic block is elastically in contact with the bottom end face of the right connecting seat, and the lower end of the elastic block is elastically in contact with the handle of the threaded rod; during use, the probability of the threaded rod loosening can be reduced by tightening the elastic block, which solves the problem that although the existing device can achieve adjustment, it is easy to loosen during use after adjustment, and safety accidents are easy to occur when loose; the existing device is easy to roll around when disassembled and placed, affecting the stability during placement."

[0004] In response to the above description, the applicant believes that the following problems exist: when the device is in use, two support seats are welded on the outer wall of the top, and both support seats are annular structures. When placed, the support of the two support seats can prevent the outer wall of the top from being bumped. Each support seat has grooves in a circular array on the outer wall. The grooves in the circular array together constitute the anti-rolling structure of the top. When placed, the anti-rolling of the top can be achieved by limiting the grooves. When the device is in use, the length of the device can only be adjusted by the screw, but the angle of the device may need to be adjusted when processing some parts. Utility Model Content
