[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A digital ultrasonic flaw detector includes a flaw detector body 1, a display screen 11, buttons 12, and knobs 13. A plug 2 is located at the upper end of the flaw detector body 1, and a connector 21 is inserted into the outer side of the plug 2. A fixing block 22 is fixedly connected to the upper end of the flaw detector body 1, and a limiting sleeve 23 is rotatably connected to the outer side of the fixing block 22. The limiting sleeve 23 contacts the flaw detector body 1, and the limiting sleeve 23 is threadedly connected to the connector 21. The design of the limiting sleeve 23 ensures a stable connection between the connector 21 and the plug 2.

[0022] Please see Figure 2-5The limiting sleeve 23 has a protrusion 24 fixedly connected inside. The fixing block 22 has an annular groove 25 inside. The protrusion 24 is slidably connected inside the annular groove 25. Through the design of the annular groove 25, it can cooperate with the protrusion 24 to limit the limiting sleeve 23. The outer side of the connector 21 is fixedly connected to the positioning frame 26. The positioning frame 26 contacts the limiting sleeve 23 and is slidably connected to the flaw detector body 1. Through the design of the positioning frame 26, it can position the connector 21. The flaw detector body 1 is provided with a protective mechanism 3.

[0023] Please see Figure 2-5 The protective mechanism 3 includes a mounting base 31. The mounting base 31 is fixedly connected to the outside of the flaw detector body 1. A hand guard 32 is in contact with the side of the mounting base 31 away from the flaw detector body 1. A sliding rod 33 is fixedly connected to the side of the hand guard 32 near the mounting base 31. A slider 34 is fixedly connected to the outside of the sliding rod 33. The sliding rod 33 is slidably connected to the mounting base 31, and the slider 34 is slidably connected to the mounting base 31. A limit frame 35 is fixedly connected inside the mounting base 31. The limit frame 35 is in contact with the hand guard 32, the sliding rod 33, and the slider 34. A spring 36 is provided on the outside of the limit frame 35. One end of the spring 36 is in contact with the slider 34, and the other end of the spring 36 is in contact with the limit frame 35. Through the design of the spring 36, the hand guard 32 can be driven to fit against the operator's hand. Through the design of the protective mechanism 3, the operator can keep the flaw detector body 1 stable when holding it.

[0024] The specific implementation process of this utility model is as follows: In use, by inserting the connector 21 into the plug 2, the connector 21 drives the positioning frame 26 to insert into the flaw detector body 1. Then, the limiting sleeve 23 is rotated to make the limiting sleeve 23 and the connector 21 undergo threaded movement, thereby making the connector 21 and the plug 2 connected stably.

[0025] By moving the hand guard 32 away from the mounting base 31, the hand guard 32 moves the slide bar 33, which in turn moves the slider 34 on the limit frame 35. The slider 34 then compresses the spring 36. The operator's hand is then placed between the flaw detector body 1 and the hand guard 32. After releasing the hand guard 32, the spring force of the spring 36 moves the slider 34, which in turn moves the hand guard 32 to fit against the operator's hand via the slide bar 33. This ensures that the operator can hold the flaw detector body 1 stably.
