[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, this embodiment provides a non-standard multi-purpose vernier caliper, including a device body 1. The device body 1 contains a scale body 2 and a fine-adjustment roller 11. A vernier 5 is fitted on the scale body 2, and one end of the scale body 2 is connected to a fixed foot 14. A screw hole 9 is opened in the vernier 5, and a secondary scale 6 is connected to the front end of the vernier 5. A pre-tightening bolt 12 is screwed into the screw hole 9. An inner diameter measuring jaw 8 is connected above the vernier 5, and an outer diameter measuring jaw 7 is connected below the vernier 5. One end of the fixed foot 14 is connected to a mounting base 15. A chain 17 is movably fitted in the mounting base 15, and a mounting post 16 is screwed into the mounting base 15. A pull ring 18 is fitted at one end of the chain 17. A insertion groove 19 is opened in the pull ring 18, and an insertion post 20 is screwed into the insertion groove 19. A sliding groove 22 is opened in the scale body 2, and a depth gauge 23 is installed in the sliding groove 22. A limit plate 24 is installed at one end of the sliding groove 22.

[0027] Preferably, the ruler body 2 is equipped with imperial scale 3 and metric scale 4 respectively, which facilitates the user to read the data of the measured object and increases the practicality and convenience of the device. The outer wall of the pre-tightening bolt 12 is equipped with anti-slip strips 13, and multiple anti-slip strips 13 are provided to prevent the user from slipping their hand when rotating the pre-tightening bolt 12. The fixed jaw 14 and the inner diameter measuring jaw 8 can measure the inner diameter of the object, and the fixed jaw 14 and the outer diameter measuring jaw 7 can measure the outer diameter of the object, which is convenient for the user to measure the object and provides the user with multiple object measurement methods. One end of the plug-in post 20 is connected to a handle 21, and the handle 21 is fixedly connected to the plug-in post 20. By setting the handle 21, the user can easily adjust the plug-in post 20, which increases the practicality and convenience of the device.

[0028] Preferably, the limiting plate 24 has a mounting hole 25, and a fixing bolt 26 is screwed into the mounting hole 25 to install and fix the limiting plate 24, ensuring the safety of the limiting plate 24 during use. One end of the depth gauge 23 is fitted with a protective sleeve 27, and the depth gauge 23 is movably engaged with the protective sleeve 27 to protect the depth gauge 23 and facilitate the user's installation and removal of the protective sleeve 27. A fixing post 10 is installed in the auxiliary scale 6, and the fixing post 10 is threadedly connected to the auxiliary scale 6. By setting the fixing post 10, the auxiliary scale 6 and the vernier 5 can be connected and fixed, increasing the closeness and connection between the devices and ensuring the safety of the devices during use.

[0029] The working principle and operation process of this utility model are as follows: When using the device, the user wipes the measuring jaws clean with a soft cloth, closes them, and checks whether the zero mark of the vernier 5 and the scale 2 is aligned. If they are not aligned, the zero error should be recorded. Then, the user holds the scale 2 with their right hand, moves the vernier 5 with their thumb, and holds the object to be measured (outer or inner diameter) with their left hand, positioning the object between the outer diameter measuring jaws 7 (or inner diameter measuring jaws 8). When measuring the outer dimension of a part, the line connecting the two measuring surfaces of the caliper should be perpendicular to the surface being measured. Gently move the scale frame, apply slight pressure to make the movable measuring jaw contact the part, and then read the dimension. This allows the user to conveniently use the device to measure objects from multiple angles, improving the device's practicality and convenience. When the device needs to be hung up when not in use, the user installs the mounting base 15 onto the fixed jaw 14 via the mounting post 16, then inserts the insertion post 20 into the chain 17, and finally screws the insertion post 20 onto the pull ring. The device can be easily attached to the waist or tool bag by inserting the pull ring 18 into the slot 19 of the depth gauge 23. This makes it convenient to carry, especially suitable for measurement work that requires frequent movement or switching between different work areas. It can effectively reduce the risk of loss due to negligence and protect the safety of the measuring tool. When the device needs to measure the depth of an object, the user removes the protective cover 27 from the depth gauge 23. After removing it, the user pulls the depth gauge 23 and places it on the outer wall of the object to be measured. After the measurement is completed, the protective cover 27 is put back on the depth gauge 23. This protects the depth gauge 23, ensures its safety, extends its service life, and reduces the possibility of damage from impacts.
