A clamping and fixing device

Abstract

This utility model discloses a fastening and fixing device, including a base plate, a left connecting support plate, a right connecting support plate, and left and right upper pressure support blocks. The top of the base plate is symmetrically fixed with the left and right support plates. One side of the left and right support plates is rotatably connected to one end of the connecting block via a rivet. The other side of the connecting block is rotatably connected to the left and right connecting support plates via rivets. Through a reasonable structural design, utilizing the rotatable connections between components and the cooperation of grooves and rivets, good self-locking performance is achieved, effectively preventing loosening during use. The setting of pressure plates makes unlocking simple and convenient, facilitating quick adjustment. The arc-shaped structure of the side blocks and the left and right upper pressure support blocks, along with the stable connection of each component, ensures that when the upper pressure block is under force, the pressure is transmitted to the arc of the connecting support plate, reducing the possibility of failure and facilitating the self-opening of the upper pressure block.
