[0004] When the existing walking heart machine guide sleeve limits the rotating bar material, the bar material will rub with the inner wall of the walking heart machine guide sleeve, but because there is an oil film between the bar material and the walking heart machine guide sleeve, the surface of the bar material will not be abraded, but after the walking heart machine processes the bar material for a period of time, the lubricating oil between the bar material and the walking heart machine guide sleeve will be consumed, so that the bar material and the walking heart machine guide sleeve come into direct contact, which will cause a large friction force between the guide sleeve and the surface of the workpiece, and cause scratches, abrasions and other defects on the surface of the workpiece, resulting in increased surface roughness.

[0005] Therefore, a walking heart machine guide sleeve with automatic injection lubricating oil subassembly is proposed to solve the above problems. UTILITY MODEL CONTENTS
