By adopting the scheme, the insert can be fixedly arranged on the measuring jaw through the arranged splicing structure, when a workpiece needs to be marked, the vernier caliper with the insert can be taken to the workpiece, then, the vernier can be moved firstly, the distance between the two measuring jaws is the distance required by marking, at the moment, one end can be abutted against the reference surface, the other end can be used for marking on the workpiece, and the insert is arranged on the measuring jaw through the splicing structure, so that after the insert is worn for a long time, the insert can be taken down from the measuring jaw for replacement, the service life of the vernier caliper is prolonged, the splicing structure can also prevent the release of the insert in the cross direction, and the probability of the insert from the measuring jaw during marking is reduced.
Preferably, the splicing structure comprises a groove with two measuring claws, wherein the groove is recessed at one side, close to each other, and used for the insert to be inserted, at least one splicing groove with an inclined or reduced opening end is arranged on the side wall of the groove, and the splicing block which is consistent with the splicing groove and can be embedded into the splicing groove is arranged on the insert.
By adopting the scheme, the insert is spliced to the measuring jaw through the at least one splicing groove with the inclined or reduced opening end arranged on the side wall of the groove, and then a worker can use the vernier caliper for marking.
Preferably, the cross section of the splicing groove is trapezoid and/or circular arc with reduced opening.
By adopting the scheme, the section shape of the splicing groove is set into the trapezoid and/or circular arc shape with the reduced opening, so that the probability that the insert is separated from the measuring jaw during scribing can be reduced, and a worker can scribe a workpiece by using the vernier caliper.
Preferably, the splicing groove is in interference splicing fit with the splicing block.
By adopting the scheme, the splicing groove and the splicing block are spliced in an interference fit manner, the splicing block can be arranged in the splicing groove, so that the fixation between the insert and the measuring jaw is realized, and the probability of the insert falling out of the measuring jaw can be reduced.
Preferably, the splicing grooves are fixedly connected with the splicing blocks through glue after being spliced in a gap.
By adopting the scheme, the splicing groove and the splicing block are spliced in a mode of adding glue through clearance fit, and the splicing block can be installed in the splicing groove, so that the fixation between the insert and the measuring jaw is realized, and the probability of the insert falling out of the measuring jaw can be reduced.
Preferably, the hardness of the material used for the insert is greater than the hardness of the material used for the measuring jaw.
By adopting the scheme, the hardness of the material used by the insert is higher than the hardness of the probability used by the measuring jaw, so that the insert can leave more obvious scratches on the workpiece when the workpiece is marked, and subsequent processing of the workpiece by workers is facilitated.
The utility model has the remarkable technical effects due to the adoption of the technical scheme: the square clamp has the advantages that the insert can be fixedly mounted on the measuring jaw through the splicing structure, when a workpiece needs to be marked, the square clamp with the insert can be taken to the workpiece, then, the vernier can be moved firstly, the distance between the two measuring jaws is the distance needed by marking, at the moment, one end of the square clamp can be abutted against the reference surface, the other end of the square clamp can be used for marking on the workpiece, and the insert is mounted on the measuring jaw through the splicing structure, so that after the insert is worn for a long time, the insert can be taken down from the measuring jaw to be replaced, the service life of the square clamp is prolonged, the splicing structure can also prevent the square clamp from loosening, and the probability of the insert from the measuring jaw during marking is reduced.
