The test hole is located within the slider's movement range on the guide rail, and the slider is connected to a mounting plate for mounting the DPT. Its function is to adjust the height of the DPT on the mounting plate through the guide rail, allowing the DPT to be aligned with the test probe at the same height.

[0006] Furthermore, the bottom surface of the mounting plate is provided with support ribs, and the distance between the bottom end of the support ribs and the mounting plate gradually decreases as the mounting plate moves away from the mounting frame. The purpose of these support ribs is to enhance the supporting strength of the mounting plate.

[0007] Furthermore, the mounting bracket is provided with a connecting plate for connecting to the test probe, and the connecting plate is provided with connecting holes for connecting to the test piece by bolts.

[0008] Furthermore, the connecting plate has multiple connecting holes evenly distributed along the extension direction of the guide rail. The purpose of this is to adjust the mounting height of the test piece on the connecting plate by adjusting the distribution direction of the connecting holes.

[0009] Furthermore, the mounting plate is provided with mounting slots for mounting the test piece.

[0010] Furthermore, the length direction of the mounting strip hole is perpendicular to the guide rail. Its function is to allow adjustment of the position of the test piece on the mounting plate in the front-to-back direction.

[0011] Furthermore, the guide rail is in the form of two parallel circular tubes, and the sliding member is a circular tube sleeved outside the guide rail.

[0012] Furthermore, the guide rail is a straight plate with parallel sides on both sides, and the sliding member is a concave block embedded on both sides of the guide rail.

[0013] Furthermore, on the connecting plate connected to the mounting plate, the guide rail is arranged parallel to the connecting plate, and a test probe cavity is provided between the guide rail and the connecting plate, with the test probe located inside the test probe cavity.

[0014] Furthermore, the mounting plate is slidably connected to a support platform for supporting the test piece via bolts passing through the mounting strip holes.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting the guide rail, the height of the test piece on the mounting plate can be adjusted so that the test piece and the test probe can be aligned at the same height.

[0024] Example 1

[0025] An adjustable test piece holder, such as... Figure 1 As shown, the device includes a mounting bracket 1 for mounting a test probe 12. The mounting bracket 1 has a test hole 2 for the test probe 12 to pass through. A guide rail 3 is provided on the mounting bracket 1, and a slider 4 is slidably connected to the guide rail 3 for moving along the extension direction of the guide rail 3. The test hole 2 is located within the movement range of the slider 4 on the guide rail 3. The slider 4 is connected to a mounting plate 5 for mounting a test piece. Its function is to adjust the height of the test piece on the mounting plate 5 by setting the guide rail 3, so that the test piece and the test probe 12 can be aligned at the same height.

[0026] Specifically, such as Figure 1 As shown, the bottom surface of the mounting plate 5 is provided with supporting ribs 6, and the distance between the bottom end of the supporting ribs 6 and the mounting plate 5 gradually decreases as the mounting plate 5 moves away from the mounting bracket 1. Its function is to enhance the supporting strength of the mounting plate 5 through the provision of supporting ribs 6.

[0027] Specifically, such as Figure 1 As shown, the mounting bracket 1 is provided with a connecting plate 7 for connecting to the test probe 12. The connecting plate 7 is provided with a connecting hole 8 for connecting to the test piece via bolts. The connecting hole 8 is a threaded hole. Its function is to allow the test piece, after its height has been adjusted, to be fixed to the connecting plate 7 via bolts through the connecting hole 8.

[0028] Specifically, such as Figure 1 As shown, the connecting plate 7 has a plurality of connecting holes 8 evenly distributed along the extension direction of the guide rail 3. The function of these holes is to allow adjustment of the mounting height of the test piece on the connecting plate 7 by adjusting the distribution direction of the connecting holes 8.

[0029] Specifically, such as Figure 1 As shown, the mounting plate 5 is provided with mounting strip holes 9 for mounting the test piece.

[0030] Specifically, such as Figure 1 As shown, the length direction of the mounting slot 9 is perpendicular to the guide rail 3. Its function is to allow adjustment of the position of the test piece on the mounting plate 5 in the front-to-back direction by means of the mounting slot 9.

[0031] Specifically, such as Figure 1 As shown, the guide rail 3 is in the form of two parallel circular tubes, and the sliding member 4 is in the form of a circular tube sleeved outside the guide rail 3.

[0032] The working principle of this embodiment is explained as follows: First, the test piece is connected to the mounting strip hole 9 of the mounting plate 5 by bolts. Then, the mounting plate 5 is moved up and down to align the height of the test piece with that of the test probe 12. After that, the bolts are passed through the through hole and the connection hole 8 on the mounting plate 5 to connect and fix it, and the test of the test piece can be started.

[0034] Specifically, such as Figure 2 As shown, the guide rail 3 is a straight plate with parallel arrangement on the left and right sides, and the sliding member 4 is a concave block embedded on the left and right sides of the guide rail 3.

[0035] Specifically, such as Figure 2 As shown, the connecting plate 7 is connected to the mounting plate 5. The guide rail 3 is arranged parallel to the connecting plate 7. A test probe cavity 10 is provided between the guide rail 3 and the connecting plate 7, and the test probe 12 is located inside the test probe cavity 10. The connecting hole 8 on the connecting plate 7 is a through hole, and the test probe cavity 10 is provided with a threaded hole corresponding to the connecting hole 8.

[0036] Specifically, such as Figure 2 As shown, a support platform 11 for supporting the test piece is slidably connected to the mounting plate 5 by bolts passing through the mounting strip hole 9.

[0037] The working principle of this embodiment is explained as follows: The test piece is installed on the support platform 11. The support platform 11 is moved back and forth on the mounting plate 5 and fixed by bolts passing through the mounting strip hole 9. Then, the mounting plate 5 is moved up and down to align the height of the test piece with the test probe 12. The bolts are then passed through the connecting hole 8 and connected to the threaded hole on the test probe cavity 10 for fixation. The test piece can then be tested.

[0038] The rest of the structure and working principle are the same as in Example 1.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
