Description

Technical Field

[0001] The utility model relates to the technical field of oven hook claw sensor mechanisms, in particular to an oven hook claw sensor mechanism. Background Art

[0002] The original hook had no contact sensor. When the hook was unhooked from the needle frame, the servo motor would continue to push the hook to the designated position, causing abnormal line stop alarms and scrapped products.
