AI Technical Summary
Existing dental jaw distance measurement tools are prone to cross-infection risks in high-frequency use scenarios. Furthermore, the precision electronic components are not resistant to high temperature, high pressure, or strong corrosion sterilization, and traditional sterilization methods can easily damage the equipment, increasing the accumulation of viral load.
A novel dental jaw distance measuring ruler has been designed. Through a detachable contact ball and a retaining ball structure, the contact ball can be replaced independently for each patient. Combined with an adjustable lighting structure, it improves the ease of operation and safety.
It effectively reduces the risk of infection, improves diagnostic and treatment efficiency and safety, while ensuring the durability and accuracy of the measuring tools.

Abstract
Claims
1. A new type of dental arch length measuring scale comprising a column (1), characterized in that: The outer wall of the column (1) is slidably connected to a slide cylinder (2). Both the slide cylinder (2) and the outer wall of the column (1) are fixedly connected to a connecting column (3). The inner wall of the connecting column (3) is slidably connected to a slide column (4). One side of the slide column (4) is fixedly connected to a contact ball (5). The outer wall of the slide column (4) has two grooves (6). The inner wall of the connecting column (3) is slidably connected to two limiting columns (7). The sides of the two limiting columns (7) that are close to each other are fixedly connected to a locking ball (8). The outer walls of the two locking balls (8) are fitted with springs (9). The outer wall of the slide cylinder (2) is fixedly connected to a clamping assembly.
2. A novel dental arch length measuring scale as claimed in claim 1, wherein: The clamping assembly includes a support column (11), one side of which is fixedly connected to the outer wall of the slide cylinder (2), and the other side of which is rotatably connected to two rotating columns (12). The outer walls of the two rotating columns (12) are rotatably connected to clamping blocks (13), and the other side of the clamping blocks (13) is fixedly connected to a fixing block (14).
3. A novel dental arch length measuring scale as claimed in claim 1, wherein: One side of the spring (9) is fixedly connected to the inner wall of the connecting column (3), and the other side of the spring (9) is fixedly connected to the outer wall of the ball (8).
4. A new type of dental arch length measuring scale according to claim 1, characterized in that: The outer wall of the contact ball (5) is in contact with one side of the connecting column (3), and the outer wall of the locking ball (8) is slidably connected to the inner wall of the connecting column (3).
5. A novel dental arch length measuring scale as claimed in claim 1, wherein: The outer wall of the ball (8) is slidably connected to the outer wall of the sliding column (4), and the outer wall of the ball (8) is in contact with the inner wall of the groove (6).
6. A new type of dental arch length measuring scale according to claim 2, characterized in that: The clamping block (13) has a semi-circular cross-section, and the slide cylinder (2) is equipped with a display screen (16).
7. A novel dental arch length measuring scale as claimed in claim 6, wherein: The two clamping blocks (13) are in contact on one side, and the two fixing blocks (14) are fixedly connected by screws (15).
