[0019] In order to further understand the purpose, structure, features and functions of the utility model, the following detailed description is made in conjunction with the embodiments.

[0020] Please refer to Figs. 1 to 3The utility model provides an inside groove position auxiliary measuring device of air spring piston, the device includes accessory handle 1 and card 2, detachable setting between accessory handle 1 with card 2, accessory handle 1 is equipped with operating end 11 and fixed end 12, be equipped with groove 13 on fixed end 12, the shape of groove 13 is same with the shape of card 2.

[0021] The detachable design between the accessory handle 1 and the card 2 makes the device easy to install and disassemble, and the user can quickly adjust or replace the card 2 according to actual needs, improving the convenience of use. The groove 13 on the fixed end 12 is the same shape as the card 2, which can ensure that the card 2 perfectly fits the position of the internal groove of the piston. Through this precise fit, the measurer can accurately determine the groove position, avoid errors, and improve the accuracy of measurement.

[0022] Preferably, the operating end 11 is also provided with anti-slip lines.

[0023] The anti-slip lines can effectively increase the friction force when the user operates, preventing the hand from slipping and thus improving safety and stability. In some high-frequency operations or harsh environments (such as wet or oily environments), the anti-slip lines design can ensure more accurate operation, reduce mistakes, and improve the overall user experience.

[0024] Preferably, the fixed end 12 is in the form of an incomplete closed cylinder.

[0025] The use of an incomplete closed cylinder design can facilitate the insertion and fixation of the card 2, avoiding the limitations of a fully enclosed design and making assembly more convenient.

[0026] The incomplete closure can also provide a certain elasticity or movement space, which can adapt to more changes or adjustments during dynamic operation or use, avoiding damage or deformation of the card 2 due to excessive pressure.

[0027] Preferably, the card 2 is in the form of a half-moon arc, and the curvature of the card 2 is smaller than the curvature of the fixed end 12.

[0028] The arc design of the card 2 can provide better adaptability, making it easier to cooperate and securely fix with the fixed end 12. The difference in curvature can make the card 2 more easily enter or exit the fixed end 12, reducing the resistance during operation.

[0029] The design of the curvature being smaller than the fixed end 12 can effectively avoid excessive friction between the card 2 and the fixed end 12, reducing the risk of card damage or deformation and improving the service life of the card.

[0030] Preferably, the end of the card 2 is also provided with a guide structure for inserting the internal groove of the piston.

[0031] The guide structure can effectively guide the card 2 to align with the groove inside the piston during installation or operation, reducing the difficulty of installation caused by asymmetric insertion or errors.

[0032] Through the guide structure, the card can be inserted more smoothly during the insertion process, reducing wear and resistance, thereby improving operation efficiency and stability.

[0033] The guide structure can also reduce damage to components and improve the service life of the overall device.

[0034] Preferably, the card 2 is made of a material with a certain flexibility.

[0035] Using a flexible material can make the card 2 have a certain elasticity when subjected to external pressure, avoiding brittle fracture of the card, thereby improving the durability of the card.

[0036] Flexible materials can also better adapt to various changes during operation, especially when stressed or deformed, they can return to their original shape without permanent damage.

[0037] In complex assembly or disassembly processes, flexible materials can better adapt to different environments and conditions, increasing the versatility and adaptability of the product.

[0038] Preferably, the middle part of the auxiliary handle 1 is provided with a spiral structure, and the two ends of the spiral structure are also provided with limiting structures.

The rotating action of the piston is usually to change the working state of the tool, or in some cases, to help adjust the measurement area to the appropriate position; the auxiliary handle 1 is detached after the operation is completed, which means that the measuring tool is no longer manually controlled, and usually at this time the measuring system has been stabilized, and the auxiliary handle 1 is detached for automatic measurement or more accurate calculation; after the auxiliary handle 1 is detached, the depth data of the groove is read through the measuring instrument; at this time, the depth of the groove is determined by the cooperation of the piston position, the card and the rotating mechanism. Mechanical pointers or numerical displays may be used to read the data; according to the measured groove depth information, the groove position is determined through mathematical formula or calculation rule. This involves the correspondence between the preset depth and position, and the calculation of the groove position or other related parameters;
