The invention discloses a locking type inertia switch which comprises a magnet (2), a screw (6) a spring mass block (1), a conductive column (3), a shell (4) and a cover plate (5), wherein one end ofthe spring mass block (1) is fixedly connected with the shell (4), the other end of the spring mass block (1) keeps a certain distance from the shell (4), one end of the conductive column (3) is a cylinder and is fixedly arranged in a conductive column hole in the cover plate (5) in an interference fit mode (5), and the other end of the conductive column (3) is a rectangular sheet, the cover plate(5) is fixedly installed with the shell (4) through the screw (6) to realize locking in place. According to the locking type inertia switch, when the spring mass block senses overload, the spring mass block overcomes the force resistance of the spring under the action of inertia force and the suction force of the spring mass block and the magnet until the spring mass block is in contact with theconductive column, so that the on and off of the circuit are realized, and the in-place locking function is achieved.

The invention discloses a coating scraper with an automatic abrasion alarming switch, and particularly relates to a contact type coating scraper or blade for scraping ornament of a solution on a roller in a gravure coating / printing, and relief block coating / printing technology. The coating scraper is provided with a micro hole which is a straight blind hole; the bottom of the straight blind hole reaches the critical line of the blade abrasion loss when the scraper is scraped; the opening part of the micro hole is provided with an alarming switch lead connected with the automatic alarming switch. When the scraper blade is abraded to the critical line, the bottom of the blind hole is worn to form a through hole; after the solution enters the through hole, the solution is in contact with the alarming switch lead, and the automatic alarming switch is triggered.
