The top of the limiting slider 409 is fixedly connected. The inside of the connecting rectangular block 405 is provided with a rectangular groove. The connecting rectangular block 405 is slidably connected to the top surface of the connecting frame 2. The rectangular groove allows the connecting rectangular block 405 to slide against the surface of the connecting frame 2, ensuring the normal use of the device. The distance from the back of the sliding block 403 to the back inside of the connecting block 401 is adapted to the width of the inner scale plate 402. The sliding block 403 is slidably connected to the front of the inner scale plate 402.

[0026] The counterweight balancing device 7 includes a placement block 701, a first counterweight block 702, a first magnetic connector 703, a magnetic column 704, a second counterweight block 705, and a second magnetic connector 706.

[0027] During use, the operator needs to maintain the balance of the plumb bob body 6 and ensure it is vertical. The balance can be adjusted according to the placement location. When placed on a plane with a lower left and higher right, the left limiting slider 409 should be at the higher position and the right limiting slider 409 at the lower position to ensure the plumb bob body 6 is vertical. During installation, the fixing bolt 411 can be unscrewed from the inside of the connecting rectangular plate 410. Then, the limiting slider 409 can be held and slid along the side of the connecting frame 2. Adjust the left and right limiting sliders 409, placing the left limiting slider 409 at the top, so that the threaded connection hole inside the left connecting rectangular plate 410 aligns with the top left side of the connecting frame 2. Align the threaded grooves, then unscrew the fixing bolt 411. The left side can be gradually adjusted until the main body 6 of the plumb bob is in a vertical state. The initial vertical state of the plumb bob can be adjusted so that the device can be set with adjustment components to make the entire plumb bob in a vertical and balanced state. The effect is good when in use. A counterweight balancing device 7 is set on the side of the balance adjustment device 4. When the left and right limit sliders 409 are at their maximum distance and still cannot be balanced, the counterweight needs to be added to increase the weight on one side. Align the magnetic column 704 with the side of the first magnetic connector 703 and insert it. The setting of the second magnetic connector 706 can extend to install multiple counterweights, which can better adapt to the balance and has a strong adaptability.
