A measuring cone rod 503 is fixedly connected to the bottom end of the lifting rod 501, and the bottom end of the measuring cone rod 503 penetrates the support plate 1. Adjusting teeth 502 are equidistantly arranged on one side of the surface of the lifting rod 501. A reading plate 504 penetrates the top of the mounting box 3 on the side away from the lifting rod 501. The reading plate 504 is located away from the lifting rod 501. A measuring scale 505 is provided on one side of the rod 501. Moving tooth blocks 506 are equidistantly arranged on the side of the reading plate 504 near the lifting rod 501. A guide rod 507 is provided on the side of the inner cavity of the mounting box 3 near the reading plate 504. A guide block 508 is fixedly connected to the bottom of the side of the reading plate 504 away from the moving tooth blocks 506. A rotating shaft 509 passes through one side of the mounting box 3. The rotating shaft 509 is located between the lifting rod 501 and the reading plate 504. A drive gear 511 and a transmission gear 512 are fixedly connected to the surface of the rotating shaft 509. A driven gear 513 is meshed with the upper oblique part of the transmission gear 512.

[0026] like Figure 2 , Figure 3 As shown, the upper and lower ends of the guide rod 507 are fixedly connected to the upper and lower inner walls of the mounting box 3, respectively. The inner wall of the guide block 508 is slidably connected to the surface of the guide rod 507. The drive gear 511 is meshed with the lifting rod 501 through the adjusting gear block 502. The driven gear 513 is meshed with the reading plate 504 through the moving gear block 506.
