A leather notcher

Abstract

The invention discloses a leather groove digger, which belongs to the technical field of leather goods manufacturing. It mainly includes a cutter bar, an adjustment piece and a cutter head. The cutter bar includes a shaft, a mounting rod slidably arranged on the rod body, and a linkage rod fixedly installed on the mounting rod. The cutter head is installed on the mounting rod. The length direction of the linkage rod is The sliding directions of the mounting rods on the rod body intersect. The adjusting member includes a fixedly connected gear rod and a sliding rod. On the rod, the sliding rod is slidably arranged on the shaft, and the sliding direction of the sliding rod on the shaft intersects with the sliding direction of the installation rod on the shaft. The force keeps the slider always moving away from the lever. The leather groove digger of the present invention can conveniently adjust the distance according to the different requirements for the distance between the groove and the edge of the leather.

Description

technical field [0001] The invention relates to the technical field of leather goods manufacturing, in particular to a leather groove digger. Background technique [0002] The existing leather grooving device comprises a cutter bar and a gear rod installed on the cutter rod and side by side with the cutter head, wherein the gear rod is slidably arranged on the cutter rod, and the gear rod is fixed on the cutter rod by a locking screw. The gear bar is against the edge of the leather, and the leather notcher is moved so that the knife head cuts a groove on the leather along the edge of the leather. According to the different requirements for the distance between the groove and the edge of the leather, the distance between the gear bar and the knife head needs to be adjusted , while the existing leather grooving device needs to be difficult to control the movement amount of the gear lever when adjusting the gear lever, and the operation is time-consuming and laborious.
