Sewing machine presser foot capable of cutting threads

Abstract

The invention relates to a sewing machine presser foot capable of cutting threads. The presser foot comprises a bottom plate and a connecting rod, wherein the bottom plate extends horizontally; the connecting rod is arranged on the bottom plate and longitudinally extends upwards; the connecting rod comprises two sides parallel to the extension direction of the bottom plate; the bottom plate comprises a front end with a needle hole or a needle penetration nick; and the other end of the bottom plate is a rear end. The presser foot is characterized in that a blade vertical to one side of the connecting rod is arranged on the side; and an elongated cutting edge is arranged on the upper part of the border on the side, close to the rear end of the bottom plate, of the blade and extends in the same direction with the border. The sewing machine presser foot has the following beneficial effects: the thread cutting blade is combined on the sewing machine presser foot, and the blade is convenient to use and is hidden, thus ensuring that the fingers of operators are hurt less possibly; in addition, a movable elastic protection cover is arranged on the blade and has a barrier effect on the unused blade, thus further improving the safety; and the sewing machine presser foot can be assembled and disassembled freely, and is flexible and practical.

Description

technical field [0001] The invention relates to a sewing machine presser foot, in particular to a sewing machine presser foot with an additional safety thread cutting function. Background technique [0002] When the sewing machine completes a sewing operation, the upper thread and the lower thread need to be cut off. At present, manufacturers generally install cutters or scissors on the head of popular home sewing machines, so that users can manually cut the thread by themselves. Although it is convenient to set the cutting knife on the machine head for thread cutting, the distance of suture pulling is long, which will cause the waste of suture after many times and increase the number of times to replace the bottom thread. The cutter is set on the presser foot of the sewing machine at a suitable height and position, which is convenient for the operator to cut the thread and also helps to save the upper thread. However, for the convenience of use, the common cutter edge is ...
