[0033] In the embodiments of the present invention, please refer to Figure 5 and Figure 6 The auxiliary structure 9 includes an auxiliary frame 91, which is slidably connected to the inner measuring claw 3. An auxiliary groove 92 is provided on the surface of the inner measuring claw 3. An auxiliary rod 93 is slidably connected to the inner wall of the auxiliary groove 92. The auxiliary rod 93 is fixedly connected to the inner wall of the auxiliary frame 91. A positioning rod 94 is threadedly inserted on the surface of the auxiliary frame 91. The auxiliary frame 91 is conveniently installed on the inner measuring claw 3. The auxiliary frame 91 is used to increase the length of the inner measuring claw 3, so that the inner measuring claw 3 can measure the inner diameter of a multi-layer circular hole with a certain depth. The disassembly and assembly operation is simple and convenient. , it is highly practical. One end of the positioning rod 94 away from the auxiliary frame 91 is fixedly connected with a plurality of anti-skid protrusions 95.

When the positioning rod 94 is rotated to limit the auxiliary frame 91, the protective pad 96 reduces the wear of the positioning rod 94 on the inner measuring claw 3.

[0034] The working principle of a multifunctional measuring tool for part quality inspection provided by the utility model is as follows: when it is necessary to use a vernier caliper to inspect the quality of a part, the inner measuring claw 3 is inserted into the circular hole on the part, the vernier ruler 2 is moved so that the two inner measuring claws 3 are against the inner wall of the circular hole, and the diameter of the circular hole is measured. The reading of the diameter of the circular hole will be displayed on the digital display 6. Similarly, the part to be measured is placed between the two outer measuring claws 4, the vernier ruler 2 is moved so that the two outer measuring claws 4 clamp the part, and the length of the part is measured. The set screw 5 can be tightened The position of the vernier ruler 2 is limited. Similarly, the depth gauge 7 is inserted into the hole to measure the depth of the hole. However, this operation will cause the following problems: the length of the outer measuring claw 4 is small, resulting in a small measuring range and application range of the outer measuring claw 4. When the length of the special-shaped part is greater than the outer measuring claw 4, the clamping position of the outer measuring claw 4 is easily restricted by the main ruler 1, and the practicality is low. By setting the adjustment structure 8, the limit rod 87 is rotated, and the limit rod 87 moves along the moving plate 81 toward the direction away from the outer measuring claw 4 with the help of the thread, and the limit rod 87 drives The limit plate 88 is away from the outer measuring claw 4. At this time, the movable plate 81 can be slid to pull the movable plate 81 in the direction away from the main scale 1. In this process, the movable plate 81 moves along the arc surface of the support frame with the help of the slide groove 83. After the movable plate 81 is extended to a certain length from the outer measuring claw 4, the limit rod 87 is rotated in the opposite direction. The limit rod 87 drives the limit plate 88 to move in the direction close to the outer measuring claw 4 with the help of the thread until the limit plate 88 is tightly against the outer measuring claw 4, so that the position of the movable plate 81 is fixed. The movable plate 81 is further limited by the round rod 89. The movable plate 81 is made more stable during movement, and the friction on the surface of the movable plate 81 is increased by the anti-slip pad 85, which makes it convenient for the user to adjust the extended length of the movable plate 81. The limiting plate 88 is further limited by the round rod 89, so that the limiting plate 88 is more stable when moving along the limiting groove 86, thereby extending the movable plate 81 in the direction away from the outer measuring claw 4, and increasing the length of the outer measuring claw 4 by using the movable plate 81, thereby expanding the measuring range and application range of the outer measuring claw 4. The movable plate 81 can be conveniently stored and limited, and the operation is simple and convenient, and the practicability is high.

[0035] When the inner measuring claw 3 is used to measure the hole on the part, if there are one or more circular holes in the circular hole, and the circular hole has a certain depth, the length of the inner measuring claw 3 is small, and the penetration distance of the inner measuring claw 3 is limited by the main ruler 1. By setting the auxiliary structure 9, the auxiliary frame 91 is aligned with the inner measuring claw 3, and the auxiliary frame 91 is operated to slide on the inner measuring claw 3. During this process, the auxiliary rod 93 in the auxiliary frame 91 moves along the auxiliary groove 92 to limit the auxiliary frame 91. According to the depth of the hole to be measured, the auxiliary frame 91 is slidably sleeved on the position of the inner measuring claw 3, and then the positioning rod 94 is rotated, and the positioning rod 94 is rotated. By moving toward the inner measuring claw 3 with the help of the thread, the straight positioning rod 94 squeezes the inner measuring claw 3, so that the position of the auxiliary frame 91 is fixed. The anti-slip protrusion 95 increases the friction of the operating end of the positioning rod 94, which is convenient for the user to rotate the positioning rod 94. When the positioning rod 94 is rotated to limit the auxiliary frame 91, the protective pad 96 reduces the wear of the positioning rod 94 on the inner measuring claw 3, so that the auxiliary frame 91 can be conveniently installed on the inner measuring claw 3, and the auxiliary frame 91 is used to increase the length of the inner measuring claw 3, so that the inner measuring claw 3 can conveniently measure the inner diameter of the multi-layer circular hole with a certain depth. The disassembly and assembly operation is simple and convenient, and the practicability is high.

[0036] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
