[0003] However, when using a digital caliper for depth measurement, the user directly pushes the cursor to move the depth rod toward the object to be measured. Due to the different thrusts of the fingers, excessive force can easily damage the depth rod and cause measurement errors. In addition, the movement range of the cursor is limited. Therefore, we need to consider how to solve this problem. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-Figure 5 A digital caliper with adjustable measuring depth comprises a ruler body 1, an outer wall of the ruler body 1 is slidably connected with a vernier 2, one side of the ruler body 1 and the vernier 2 are fixedly connected with two outer measuring claws 3, the two outer measuring claws 3 are used to measure the outer size, the other side of the ruler body 1 and the vernier 2 are fixedly connected with inner measuring claws 4, the two inner measuring claws 4 are used to measure the inner diameter size, a mounting groove 5 is provided in the ruler body 1, a slide groove 6 is provided in the vernier 2, a threaded rod 7 is rotatably connected between the inner walls on both sides of the slide groove 6, one end of the threaded rod 7 passes through the vernier 2 and extends to the outside, a knob 8 is fixedly connected to the end of the threaded rod 7 located at the outside, a protective layer is arranged on the outer side of the knob 8, the protective layer is made of rubber, a slider 9 is threadedly connected to the threaded rod 7, and the slider 9 is slidably connected to the inner wall of the slide groove 6;
[0023] Among them, one end of the slider 9 extends into the installation groove 5 and is fixedly connected with a depth gauge rod 10. The depth gauge rod 10 is slidably connected to the inner wall of the installation groove 5. The sliding cursor 2 can move the depth gauge rod 10, and slowly turning the knob 8 makes the threaded rod 7 rotate, so that the slider 9 moves with the depth gauge rod 10, which can achieve fine-tuning of the depth gauge rod 10, avoiding excessive sliding of the cursor 2, resulting in damage to the depth gauge rod 10 and measurement errors. Moreover, with the cooperation of the structures such as the threaded rod 7, the knob 8 and the slider 9, even if the cursor 2 moves to the limit, the depth gauge rod 10 can still be moved, increasing the measurement range of the depth gauge rod 10, so that objects at different depths can be measured. A limit block 11 is fixedly connected to one side of the ruler body 1, and the limit block 11 is used to prevent the cursor 2 from detaching from the ruler body 1;
[0024] Among them, one side of the ruler body 1 is rotatably connected to two first rotating shafts 12, and the two first rotating shafts 12 are fixedly connected to extension rods 13, and the two extension rods 13 are opened with through holes 14. The two side walls of the limit block 11 are rotatably connected to second rotating shafts 15, and the two second rotating shafts 15 cooperate with the corresponding through holes 14. The opposite ends of the two second rotating shafts 15 are fixedly connected to rotating blocks 16. When in use, the two rotating blocks 16 are rotated to be parallel to the corresponding through holes 14. After the limit of the two extension rods 13 is released, the two extension rods 13 can be rotated perpendicular to the ruler body 1, thereby increasing the width of the ruler body 1 so that it can contact the object to be measured and improve the stability during measurement. When not in use, the two extension rods 13 are rotated to fit with the ruler body 1, and then the two rotating blocks 16 are rotated to be perpendicular to the corresponding through holes 14 so that the two extension rods 13 are limited. This makes it convenient to store the digital caliper.
[0025] In the present invention, when in use, the two rotating blocks 16 are rotated so that the two rotating blocks 16 are parallel to the corresponding through openings 14, so that the two extension rods 13 are released from the limit, and then the two extension rods 13 are rotated perpendicular to the ruler body 1, so that the width of the ruler body 1 can be increased, which is convenient for contact with the object to be measured and improves the stability during measurement. Then, the two extension rods 13 and the end wall of the ruler body 1 are pressed against the object to be measured, and the sliding cursor 2 makes the depth ruler rod 10 move, and the depth ruler rod 10 is moved above the object to be measured;
[0026] At this time, the knob 8 can be slowly turned to rotate the threaded rod 7, so that the slider 9 can slowly move down with the depth gauge rod 10 until the depth gauge rod 10 moves to the bottom, and the depth measurement can be performed. Through the coordination of the threaded rod 7, the knob 8 and the slider 9, the depth gauge rod 10 can be fine-tuned, and even when the cursor 2 moves to the limit block 11, the depth gauge rod 10 can still be moved, which increases the moving range of the depth gauge rod 10 and enables the depth measurement of objects at different depths.
[0027] After the measurement is completed, the knob 8 is rotated in the opposite direction to rotate the threaded rod 7, thereby causing the slider 9 to move up with the depth gauge rod 10 and return to its original position, and then the cursor 2 is slid back to its original position, and then the two extension rods 13 can be rotated to make the two extension rods 13 fit with the ruler body 1. After fitting, the two rotating blocks 16 are rotated to make the two rotating blocks 16 perpendicular to the corresponding through holes 14. At this time, the two extension rods 13 are limited on the ruler body 1, which can reduce the area of the ruler body 1 and facilitate the storage of the ruler body 1.
[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
