Description

Technical Field

[0001] This utility model relates to the field of clamping and positioning technology for holding scissor blades during scissor processing, and particularly to a scissor blade clamping and positioning device. Background Technology

[0002] Existing scissor blade clamping and positioning devices rely on manual holding of the scissor blades and pressing them against a grinding tool for processing. However, this method struggles to guarantee grinding quality and reduces work efficiency. For example, Chinese patent disclosure "Clamping and Positioning Device for Scissor Blades" (application number "CN201210057677.X") describes a device with a U-shaped groove mounting base. At least two connecting shafts are movably arranged between the two arms of the U-shaped groove. The connecting shafts are sequentially fitted with swing brackets of the same number as the connecting shafts. Each swing bracket is equipped with a fastening mechanism that can be fastened to one of the connecting shafts. At least two swing brackets are not fastened to the same connecting shaft. The mounting base also has a mounting groove into which a scissor blade mounting plate is embedded. The scissor blade mounting plate is equipped with a blade pressure plate that fastens the scissor blades. This device greatly improves work efficiency. However, during the use of this device, the operator holds the grinding tool to grind the scissor blades. Grinding different parts of the scissor blades requires manual movement of the grinding tool, which can easily cause injury to the operator. Utility Model Content

A cover plate 25 is fixedly connected to the outer surface of the rotating shaft 24.

[0025] A partition 26 is fixedly connected to the upper surface of the base 1. The partition 26 has a limit hole 27 and a connecting hole 28 inside. A rotating shaft 39 is located inside the connecting hole 28.
