When it is necessary to move, the first scale body 11 and the second scale body 12 can be quickly separated through the connecting block 321, and the magnetic block 322 of the second scale body 12 can be slidably connected with the guide groove 323, so that the folding connection can be quickly performed, and the connection stability of the first scale body 11 and the second scale body 12 can be improved by the magnetic force after the connection. When the second scale body 12 and the first scale body 11 are folded, the fixing block 324 is synchronously moved close to the magnetic block 322 of the first scale body 11, so that the two positioning blocks 325 can be driven to move away from each other and synchronously drive the corresponding limit blocks 328 to move away, so that the fixing block 324 can be moved away from each other. The fixed block 324 moves to one side of the magnetic block 322. At this time, the two limit blocks 328 are opposite to the two limit grooves 329. When the two positioning blocks 325 move, the spring 327 is synchronously squeezed. When the positioning block 325 is released, the spring 327 synchronously resets the positioning block 325 and the limit block 328, and the limit block 328 can be pushed to the inside of the adjacent limit groove 329 for clamping. The fixed block 324 can be stably connected to one side of the first ruler 11 to prevent the second ruler 12 from being in contact with the first ruler 11 during movement. In the event that the body 11 slides and separates, the connecting plate 331 and the connecting hole 332 on one side of the second ruler body 12 can be used to conveniently connect the caliper 1 to other fixing parts such as buckles through the connecting hole 332 when the caliper 1 needs to be carried, so that the caliper 1 can be conveniently carried. The arc shape of the edge of the connecting plate 331 can reduce friction and potential damage risks during carrying, making the carrying process safer. The arc edge reduces sharp angles and reduces the possibility of accidentally scratching the user or damaging other items.
