Abstract

The invention discloses a sewing machine head with a sewing machine cover. The sewing machine head comprises the sewing machine cover, wherein the sewing machine cover is of a hollow U-shaped structure and comprises a first machine cover side portion, a second machine cover side portion and machine cover ends, wherein the machine cover ends are smoothly connected with the first machine cover side portion and the second machine cover side portion, a first hanging lug is arranged at one end of the first machine cover side portion, a second hanging lug is arranged at one end of the second machine cover side portion, the first hanging lug and the second hanging lug are oppositely arranged and are parallel, and the distance between the first hanging lug and the second hanging lug is greater than or equal to the diameter of a presser rod. The sewing machine cover is fixedly connected with the presser rod, and the lower end face of the sewing machine cover is flush with the upper end face of a presser plate. A light-transmitting hole is formed in the first machine cover side portion, a thread hole is formed in the second machine cover side portion, a seam is arranged at the top end of the thread hole, the straight line where geometric centers of the light-transmitting hole and the thread hole are located is intersected with the axis of a needle bar. The bottom surfaces of the machine cover ends are higher than the bottom surface of the first machine cover side portion and the bottom surface of the second machine cover side portion. Silk, wool, cotton or artificial fiber are prevented from entering a threading hole to cause sewing thread breakage.

Description

technical field [0001] The present application relates to the technical field of sewing machines, in particular to a sewing machine head with a sewing machine cover.
