Abstract

The invention discloses a stabilizing mechanism for a cloth feeding tooth of a sewing machine, which mainly includes a support and a power source, the support is installed under the cloth feeding tooth, and the support is actuated by the power source so that the support can resist Top feeding teeth, so that the feeding teeth can maintain a certain height of biting the cloth when feeding, so as to maintain the best feeding efficiency.

Description

technical field [0001] The invention relates to a stabilizing mechanism of a cloth feeding tooth of a sewing machine, which is related to a structure supporting a cloth feeding transmission mechanism of a sewing machine. Background technique [0002] The common structure of a sewing machine with cloth feeding teeth includes: single-tooth or double-tooth feeding sewing machines, the single-tooth and double-tooth feeding sewing machines have a presser foot above the cloth feeding teeth during the cloth feeding process. The presser foot presses down on the cloth surface and cooperates with the cloth feed teeth to bite the cloth surface below the cloth surface to move the cloth. Generally, the cloth feed teeth must have the need to move up and down and forward and backward. Therefore, the cloth feed teeth will be in a suspended form. Set under the presser foot, the only supporting force comes from the transmission mechanism that pushes the end of the cloth feed tooth to move, an...
