Description

PCB cutter with improved composite coating Technical Field The utility model relates to the technical field of PCB cutters with improved composite coatings, in particular to a PCB cutter with an improved composite coating. Background Plays a critical role in PCB processing, and PCB cutters mainly include drill pins, milling cutters, special cutters, and the like, which have different functions and uses. For example, the corrosion-resistant and rust-proof composite coating PCB cutter with an authorized bulletin number of CN217967358U is provided, through the guiding effect of a thread track groove, when the main rod is retracted or extended out of the cutter protection cylinder, the movable ball is matched, so that the arc scraping block which is matched with the inner wall of the chip removal sleeve cover is retracted or extended out, the inner wall of the chip is automatically scraped, the integral protection performance is high, the corrosion and rust of the chip are effectively avoided, the integral service life of the PCB cutter is prolonged, in the use of the PCB cutter, although the elastic structure is used for cleaning scraps in the notch of the outer wall of the PCB cutter, the elastic structure is unstable, a gap exists between the inserted rod and the circular opening, the inserted rod can swing between the circular openings due to the shaking of the spring, and the PCB cutter can influence the machining due to the slight shaking of the processing of the printed circuit board, so that the shaking occurs in the work of the PCB cutter, and the normal use of the PCB cutter is influenced. Disclosure of utility model The utility model aims to solve the problem that the normal use of a PCB cutter is affected due to shaking in the working process of the PCB cutter, and provides the PCB cutter with an improved composite coating. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides an improve compound coating's PCB cutter, includes shell and round bar, the top of shell and the bottom looks rigid coupling of round bar, the inner wall rigid coupling of shell has the PCB cutter, the outer wall top processing of PCB cutter has the screw thread, the outer wall connection of screw thread has protective structure. Preferably, the protection structure comprises a vertical cylinder and vertical plates, wherein the upper part of the inner wall of the vertical cylinder is in threaded connection with the outer wall of the threads, the left side and the right side of the vertical cylinder are respectively fixedly connected with the inner walls of the two vertical plates, and the bottom of the inner wall of the vertical cylinder is fixedly connected with a brush plate. Preferably, the inner wall bristles of the brush plate are attached to the outer wall of the PCB cutter. Preferably, the outer wall of the PCB cutter is fixedly connected with a circular ring. Preferably, the outer wall of the circular ring is spliced with the inner wall of the vertical cylinder. Preferably, the outer wall interlayer of the shell is fixedly connected with a round block.
