At this time, the staff can slide the measuring block 4 to make the inner cavity of the measuring block 4 slide on the surface of the scale rod 3, and at the same time drive the L-shaped block 7 to move, so that the surface of the first slider 15 slides in the inner cavity of the first slide groove 14. When the staff slides to the measuring end point of the metal rod body 10, the staff releases the pulling force on the T-shaped rod 12, so that the pressure spring 13 releases the stored force to push the bottom end of the arc-shaped slide bar 8 to squeeze the surface of the metal rod body 10. Through the setting of the stabilizing mechanism, the staff can keep the measuring block 4 stable when measuring the metal rod body 10, prevent the measuring block 4 from being displaced by external force, and affect the measurement result, thereby further improving the stability and accuracy of the measuring device.

[0023] Reference Figure 3As shown, in this embodiment: square grooves 11 are provided on both sides of the measuring block 4, and the inner cavity of the square groove 11 is slidably connected with a T-shaped rod 12, and one end of the T-shaped rod 12 close to the arc-shaped slide rod 8 is fixedly connected to the arc-shaped slide rod 8. The staff pulls the T-shaped rod 12, driving the surface of the T-shaped rod 12 to slide in the inner diameter of the square groove 11, and at the same time drives the arc-shaped slide rod 8 to move.

[0024] Reference Figure 3 As shown, in the present embodiment: the inner cavity of the measuring block 4 is fixedly connected with a pressure spring 13, and the bottom end of the pressure spring 13 is fixedly connected with the arc slide bar 8. The staff pulls the T-shaped rod 12 to drive the arc slide bar 8 to move, so that the top end of the arc slide bar 8 squeezes and accumulates force on the pressure spring 13. Through the setting of the above structure, the rebound force of the pressure spring 13 continuously pushes the arc slide bar 8 to squeeze and limit the metal rod body 10, thereby improving the stability of the measuring block 4.

[0025] Reference Figure 3 As shown, in this embodiment: a first slide groove 14 is opened on the surface of the detection body 2, and the inner cavity of the first slide groove 14 is slidably connected with a first slider 15, and the top of the first slider 15 is fixedly connected to the L-shaped block 7.

[0026] Reference Figure 5 As shown, in this embodiment: the inner cavity of the open groove 5 is slidably connected with an arc-shaped stopper 16, and the top of the arc-shaped stopper 16 is fixedly connected with a pull ring 17, and the left end of the pull ring 17 is fitted with the right end of the metal rod body 10. When the staff needs to limit the metal rod body 10, the staff pulls the pull ring 17 to drive the arc-shaped stopper 16 to slide in the inner cavity of the detection body 2. As the arc-shaped stopper 16 moves, the arc-shaped stopper 16 drives the surface of the second sliding block 20 to slide in the inner cavity of the second sliding groove 19. While the arc-shaped stopper 16 moves, it squeezes the tension spring 18 to accumulate force, so that when the staff limits the metal rod body 10, the rebound force of the tension spring 18 continuously pushes the arc-shaped stopper 16 to squeeze and limit the metal rod body 10. Through the setting of the limiting mechanism, the measuring device can limit the metal rod bodies 10 of different lengths, further improving the applicability of the measuring device.

[0027] Reference Figure 5As shown, in the present embodiment: the inner cavity of the opening groove 5 is fixedly connected with a tension spring 18, and one end of the tension spring 18 close to the arc stop block 16 is fixedly connected to the arc stop block 16. The staff pulls the pull ring 17 to drive the arc stop block 16 to move, so that the arc stop block 16 squeezes the tension spring 18 to store force.

At this time, the staff can slide the measuring block 4 to make the inner cavity of the measuring block 4 slide on the surface of the scale rod 3, and at the same time drive the L-shaped block 7 to displace, so that the surface of the first slider 15 slides in the inner cavity of the first slide groove 14. When the staff slides to the measuring end point of the metal rod body 10, the staff releases the pulling force on the T-shaped rod 12, so that the pressure spring 13 releases the stored force to push the bottom end of the arc-shaped slide bar 8 to squeeze the surface of the metal rod body 10. Through the setting of the stabilizing mechanism, the staff can measure the metal rod body 10. The measuring block 4 is kept stable during measurement to prevent the measuring block 4 from being displaced by external forces and affecting the measurement results, thereby further improving the stability and accuracy of the measuring device. When the staff needs to limit the metal rod body 10, the staff pulls the pull ring 17 to drive the arc stopper 16 to slide in the inner cavity of the detection body 2. As the arc stopper 16 moves, the arc stopper 16 drives the surface of the second slider 20 to slide in the inner cavity of the second slide groove 19. While the arc stopper 16 moves, it squeezes the tension spring 18 to accumulate force, so that when the staff limits the metal rod body 10, the rebound force of the tension spring 18 continuously pushes the arc stopper 16 to squeeze and limit the metal rod body 10. Through the setting of the limiting mechanism, the measuring device can limit the metal rod bodies 10 of different lengths, thereby further improving the applicability of the measuring device.
