Two square grooves 7 are opened on the left side of the telescopic hollow rod 4. The pushing end of the hydraulic rod 6 is fixedly connected with a double-sided rack rod 8. The double-sided rack rod 8 is usually made of lightweight material, which helps to reduce the weight of the overall structure and facilitates installation and operation. The upper and lower inner walls of the fixed rod 3 are respectively fixedly connected with single-sided rack rods 9. The inner wall of the square groove 7 is fixedly connected with a fixed block 10. The fixed block 10 is usually designed to have sufficient strength and rigidity to withstand a large load and ensure the safety of mechanical parts during operation. The inner wall of the fixed block 10 is rotatably connected with a gear 11. The right side of the telescopic solid rod 5 is fixedly connected with a measuring assembly, which is a measuring device for fastening holes.

[0032] Reference Figure 4 The measuring assembly includes a hydraulic rod 12, a trapezoidal push block 13 is fixedly connected to the right side of the hydraulic rod 12, and the movement of the hydraulic rod 12 can be controlled by fine adjustment of the valve to achieve precise position and force control. The right side of the telescopic solid rod 5 is fixedly connected to a housing 14, which can protect the internal mechanical parts from dust, moisture, corrosion and other potential damages, and extend the service life of the equipment. The front and rear sides of the housing 14 are respectively provided with square openings 15, and the upper and lower sides of the right end of the housing 14 are respectively provided with slides 16.

The measuring telescopic device can directly reach the hard-to-reach areas without the need for additional auxiliary tools or extension devices, which can reduce the errors caused by auxiliary tools, improve the measurement accuracy, and increase the measurement range and flexibility.

[0036] Start the hydraulic rod 12, the hydraulic rod 12 will push the trapezoidal push block 13 to slide, the housing 14 will slide in the slot 19 and then push the sliding rod 17 and the sliding rod 18 to slide to both sides. The slide groove 16 can play a limiting role. The outer walls of the sliding rod 17 and the sliding rod 18 are respectively fixedly connected with the sensing device 20.
