Abstract
The invention relates to the technical field of fixing devices and discloses a fixing device for inlaying and fixing bars. The fixing device comprises a base and a plurality of studs. A plurality of inlaying grooves used for inlaying and positioning the bars are formed in the end face of the base. The top of each inlaying groove is provided with an opening. When the bars are inlaid in the inlaying grooves, the bars partially protrude out of the openings. In addition, a plurality of threaded holes which are parallel to the axial direction of the base are further formed in the base. The threaded holes penetrate through the base and are communicated with the inlaying grooves correspondingly. The studs are arranged in the threaded holes and can move in the axial direction of the studs and stretch into the inlaying grooves to abut against and fasten the bars. According to the fixing device for inlaying and fixing the bars, the inlaying grooves and the threaded holes communicated with the inlaying grooves are formed in the base, the studs are inserted in the threaded holes, and thus when the bars are inlaid in the inlaying grooves to be pre-positioned, the bars can be fastened by rotating the studs to stretch into the inlaying grooves and abut against the bars; the fixing device is simple in structure and convenient to operate, the production efficiency is improved, and the production cost is reduced.
