Description of the invention (1) [Detailed description of the present invention] [Field of the invention] This month is about a kind of overlock sewing machine, which is suitable for preventing the workpiece from being polluted by the leakage of lubricating oil. [Know-how] Generally, in an overlock sewing machine for forming a double-chain edge and an over-edge chain edge at a high speed, a connecting mechanism, a needle mechanism, and a silver feeding mechanism And at least one component of the upper loop mechanism is movable so that the component is supported by a sliding portion to contact other components, and the connecting mechanism is used to transmit the driving force of a main shaft of a sewing machine to each drive A shaft, such as a needle drive shaft, a feed drive shaft, an upper collar drive shaft and a lower collar drive shaft, the needle mechanism is used to transmit the driving force output from each of these drive shafts A needle bar, the feeding mechanism is used to transmit the driving force to a feeding iron hook, and the upper loop mechanism is used to transmit the driving force to an upper loop. I know that the sliding part of the conventional sewing machine generates abrasion powder due to the abrasion of the sliding part, and because the sewing machine operates at high speed, a sliding resistance (a frictional resistance) is generated on the sliding part to generate heat, and it is caused by the heat Victory over sticky hazards. In order to prevent the generation of abrasion powder and adhesive hazard due to the abrasion of the sliding part, in the conventional overlock sewing machine, an oil pan is arranged at the lower part of a sewing frame to store, for example, a low kinematic viscosity of about 5 to 25 cSt. Lubricating oil, and by using an oil pump, which is driven by the driving force of the main shaft of a sewing machine, to supply the stored lubricating oil to the sliding portion, or by using a _ -4- This paper standard applies to Chinese national standard () A4 Specifications (21〇 > < 297 public love ^ '' a " 564272 A7 B7 V. Description of the invention (2 The oil core supplies the stored adjusting oil to the sliding part, so as to form a adjusting oil film to prevent wear and tear. Causes the generation of abrasive powder and the danger of sticking. [Problems Solved by the Invention] However, in conventional overlock sewing machines, the amount of lubricant used to form the lubricant / month / film is based on the The sliding parts are different, and each sliding part cannot be accurately controlled. In particular, the problem is that the lubricant will leak out of the feeding part, such as a needle rod part, an upper collar part, a main Hey Swing rod and a feeding swing rod, and a workpiece such as cloth is contaminated due to the oil leakage of the lubricant. More specifically, if the supply of the lubricant is large, the lubricant leaks out of the sliding portion. In addition, it will cause contamination of the workpiece. If the supply of the lubricating oil is small, it will cause a sticky hazard. Therefore, it is difficult to have both the prevention of oil leakage and the durability of the sewing machine. A sewing machine structure allows the lubricating oil to be fed to For all sliding parts, the structure of this initial seam is complicated. In addition, the number of components and the time required for assembly will increase, so that the economic burden will increase. The present invention is made in view of this point, and has one purpose: Provide an overlock sewing machine, which can prevent the leakage of lubricating oil to pollute the workpiece and have the durability of the sewing machine. [Solution to the problem] To achieve this object, the first feature of the present invention is an overlock sewing machine, one of the sewing machines. The frame is provided with a connection mechanism housing portion for accommodating a connection mechanism for transmitting the driving force of a main shaft of a sewing machine to a needle.
