Description

Quick-change blade knives

The present invention mainly discloses a tool, especially a tool with quick blade change.

Please refer to the "Scraping tool with blade lock assembly" patent case of US Patent No. 8356415 B2, which is a scraping tool that can quickly assemble and replace the scraper. The scraping tool generally includes a tool that can be held by human hands. The handle of the force and the scraping part at the front end are mainly composed of a jaw that is centered and extends backward with a force arm of appropriate length, which can be set in the concave jaw groove on the back of the scraping part with a fixing piece. The lever fulcrum swings back and forth, and a control button is provided at the force arm position at the rear end of the jaw at the scraping part. The control button can provide vertical thrust force at the rear end of the jaw.
