DETAILED DESCRIPTION

[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combined with reference Figure 1-Figure 5 The utility model provides a portable automobile parts inspection tool, including a caliper 1, a vernier scale 2 slidably connected to the caliper 1, and a fastening screw 3 threadedly connected to the vernier scale 2. The fastening screw 3 can be threaded through the vernier scale 2 and fixed on the caliper 1, so that the position of the vernier scale 2 can be conveniently limited. A measuring claw 1 4 is arranged at the lower side of the caliper 1, and a measuring claw 2 5 is arranged at the lower side of the vernier scale 2. The back of the caliper 1 is detachably connected with a mounting plate 1 6, and a rotating block 1 8 is connected to the mounting plate 1 6 for damping rotation. The measuring claw 1 4 is fixedly connected to the rotating block 1 8. The rotating block 1 8 can be rotatably arranged, which can conveniently drive the measuring claw 1 4 to rotate in the back of the caliper 1. Until the measuring claw 4 and the caliper 1 reach a relatively parallel effect, this can prevent the measuring claw 4 from protruding and scratching. The outer surface of the rotating block 8 is fixedly connected with a tooth block group 9. Since the tooth block group 9 has multiple tooth blocks arranged in a ring shape, a limit frame 7 that is in active contact with the rotating block 8 is provided on the mounting plate 6. The setting of the limit frame 7, when the measuring claw 4 is in a vertical measuring state, in order to meet the stability of the measuring claw 4 clamped on the automobile parts, the limit frame 7 can limit the rotation path of the measuring claw 4, so as to prevent the measuring claw 4 from everting outward. The limit frame 7 is provided with a locking structure 10 for locking two adjacent tooth blocks in the tooth block group 9.

[0025] A slide groove 1 for sliding of a mounting plate 6 is arranged on the back of the caliper 1. The mounting plate 6 is connected to the slide groove 1 by a bolt 1. In the present application, the mounting plate 6 is arranged in a convex structure, so that it can be effectively confined in the slide groove 1, and the position setting can be hidden, thereby improving space utilization and facilitating disassembly and assembly.

[0026] The locking structure 10 includes a rectangular rod 101 that movably passes through the limit frame 7, a pull rod 102 fixedly connected to the top of the rectangular rod 101, a spring 103 sleeved on the rectangular rod 101 and a socket 104 fixedly connected to the bottom of the rectangular rod 101. The spring 103 arranged on the rectangular rod 101 is located on the inner side of the limit frame 7, and the socket 104 is movably clamped on two adjacent tooth blocks in the tooth block group 9.

[0027] Specifically, when the measuring claw 4 is set vertically, it is in the measuring state. By pulling the rectangular rod 101, it drives the holder 104 to separate from the tooth block group 9, so that the rotating block 8 can rotate freely, and the rotating block 8 can drive the measuring claw 4 to rotate and be in a parallel state with the caliper 1. At this time, the pull rod 102 is released, and under the elastic action of the spring 103, the holder 104 can be abutted against the tooth block group 9, so that the rotation of the measuring claw 4 can be limited.

[0028] The back-disassembly connection of the vernier scale 2 is provided with a mounting plate 11, on which a rotating block 12 is connected for damping rotation. The measuring claw 5 is fixedly connected to the rotating block 12, and a limit frame 13 which is in active contact with the rotating block 12 is provided on the mounting plate 11. The limit frame 13 is provided so that when the measuring claw 5 is in a vertical measuring state, in order to ensure the stability of the measuring claw 5 clamped on the automobile parts, the limit frame 13 can limit the rotation path of the measuring claw 5, thereby preventing the measuring claw 5 from everting outward. The measuring claw 14 and the measuring claw 25 are provided with interlocking positioning components.

[0029] A slide groove 2 for sliding the mounting plate 11 is arranged on the back of the vernier scale 2. The mounting plate 11 is connected to the slide groove 2 by bolt 2. In the present application, the mounting plate 11 has the same use effect as the mounting plate 1 6, so it will not be described in detail.

[0030] The positioning assembly comprises an insert rod 14 connected to the end of the measuring claw 1 4 and a slot 15 opened at the end of the measuring claw 2 5 , and the insert rod 14 is movably plugged into the slot 15 .

[0031] Specifically, when the measuring claw 1 4 is in a vertical state, the rotation of the measuring claw 2 5 can be controlled to correspond to the measuring claw 1 4 . When the limit frame 2 13 limits the path of the rotating block 2 12 , that is, the measuring claw 2 5 , the measuring claw 1 4 and the measuring claw 2 5 can be clamped on the automobile parts with reliability, and the rotation and eversion phenomenon is effectively prevented. When the measuring claw 2 5 also needs to be stored, the vernier 2 can be controlled to move a certain distance on the caliper 1 , and the rotating block 2 12 can be controlled to damp the rotation until the measuring claw 2 5 and the measuring claw 1 4 are in a horizontal state. The vernier 2 can be pushed to allow the insertion rod 14 and the slot 15 to be plugged in and correspond to each other, and the vernier 2 can be locked by tightening the screw 3. When the measuring claw 1 4 is in a locked state, the locking property of the measuring claw 2 5 can be given, thereby stabilizing the storage stability of the measuring claw 1 4 and the measuring claw 2 5 .

[0032] The bottom of the rotating block 8 is fixedly connected to an extension block 81, the measuring claw 4 is fixedly connected to the bottom of the extension block 81, the bottom of the rotating block 12 is fixedly connected to an extension block 121, and the measuring claw 25 is fixedly connected to the bottom of the extension block 121. In this application, because the back positions of the caliper 1 and the vernier ruler 2 are not on the same horizontal plane, the dimensions of the extension block 81 and the extension block 121 are reasonably set to ensure that the measuring claw 4 and the measuring claw 25 reach a horizontal state.

[0033] It is worth noting that in the present application, the rotating block 1 8 and the rotating block 2 12 are both rotationally connected via a damping shaft, so that the movements of the measuring claw 1 4 and the measuring claw 2 5 can have damping properties, satisfying the effect of rotational hovering.
