[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 5 This utility model provides a test device probe angle fine-tuning device, which includes:

[0033] Mounting bracket 1 includes a fixed rod 12 and a telescopic rod 13. One end of the fixed rod 12 has an axial sliding cavity, and one end of the telescopic rod 13 is movably installed inside the axial sliding cavity.

[0034] Vertical rotation component 2 is rotatably connected to the other end of telescopic rod 13;

[0035] Locking component 3 is installed between telescopic rod 13 and vertical rotation component 2, which can limit vertical rotation component 2 and fix it on telescopic rod 13;

[0036] The probe mounting bracket 4 is fixed on the vertical rotation assembly 2.

[0037] It should be noted that in this device, the mounting frame 1 is a basic support and positioning structure, which includes a fixed rod 12 and a telescopic rod 13, used to support the vertical rotation component 2, while the probe mounting frame 4 is installed on the vertical rotation component 2, thereby enabling the probe to be installed.

[0038] The vertical rotation component 2 is installed at one end of the telescopic rod 13, and the two are rotatably connected. Therefore, the entire vertical rotation component 2 can rotate in the horizontal direction to drive the probe to rotate together. A locking component 3 is also installed between the telescopic rod 13 and the vertical rotation component 2. The locking component 3 can lock the vertical rotation component 2 and the telescopic rod 13, so that the vertical rotation component 2 is stable on the telescopic rod 13, thereby achieving the positioning of the vertical rotation component 2.

[0039] The vertical rotation component 2 consists of two parts that can rotate relative to each other to drive the probe to rotate vertically. The two parts can also mesh with each other, so after positioning, it can meet the requirements of long-term use without slippage.

[0040] In the embodiments of this utility model, please refer to Figure 1 An installation plate 11 is welded and fixed to one end of the fixed rod 12, and a locking ring 14 is provided at the other end to lock the telescopic rod 13.

[0041] It should be noted that the telescopic rod 13 can extend and retract relative to the fixed rod 12 to adjust its overall height, while the locking ring 14 can lock the telescopic rod 13, so that the fixed rod 12 and the telescopic rod 13 are in a stable state.

[0042] In the embodiments of this utility model, please refer to Figure 3The vertical rotating assembly 2 includes a right-angled first leg 21 and a second leg 22. The first leg 21 is rotatably connected to the telescopic rod 13. A mating plate 23 is welded and fixed to one end of both the first leg 21 and the second leg 22. The two mating plates 23 are concentrically arranged, and each has a ring-shaped tooth 24 on its opposite side near the edge, so that the two mating plates 23 can be interlocked and fixed. Bolts 25 and nuts 26 are respectively provided on the two mating plates 23.

[0043] Among them, there is a groove on one side of the two mating discs 23 and near the center, and a spring 27 is provided inside the groove to press against the two mating discs 23.

[0044] It should be noted that in the vertical rotation assembly 2, the first leg 21 is rotatably connected to one end of the telescopic rod 13, enabling the entire vertical rotation assembly 2 to rotate in the horizontal direction. Both the first leg 21 and the second leg 22 have mating plates 23, which are fixed by bolts 25. At the same time, the two mating plates 23 have teeth 24 on opposite sides, so that in the locked state, the two mating plates 23 interlock with each other, resulting in a better limiting effect.

[0045] When the second tripod 22 needs to be rotated and adjusted, the bolt 25 is removed from the two mating plates 23. Under the action of the spring 27, one of the mating plates 23 can be pushed to move away from the other mating plate 23 until the teeth 24 in the two plates disengage. At this time, the second tripod 22 can be rotated and adjusted.

[0047] A rotatable connecting arm 33 is mounted on the lower end of the first stand 21 via a shaft 32. A clamping plate 34 is welded to one end of the connecting arm 33, which can engage with any slot in the gear 31. A lever plate 35 is welded to the other end of the connecting arm 33.

[0048] It should be noted that in the locking assembly 3, the gear 31 is fixed on the telescopic rod 13, and the lower end of the first leg 21 has a rotatable connecting arm 33. One end of the connecting arm 33 has a locking plate 34, which can engage with the gear 31, thereby limiting the distance between the telescopic rod 13 and the first leg 21.

[0049] The connecting arm 33 is connected to the shaft 32. A torsion spring needs to be added between the two. The elastic force applied by the torsion spring to the connecting arm 33 can make the clamping plate 34 engage with the gear 31.

[0050] In the embodiments of this utility model, please refer to Figure 5The probe mounting bracket 4 includes a base frame 41, which is fixed to the top of the second bracket 22.
