[0030] The specific settings and functions of the adjustment device 2 and the auxiliary device 3 are described in detail below.

[0031] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjusting device 2 includes a fixed plate 201, the fixed plate 201 is fixedly connected to the surface of the fixture body 1, the surface of the fixed plate 201 is slidably connected with a placement plate 202, the side wall of the placement plate 202 is fixedly connected with a connecting plate 203, the connecting plate 203 has an internal thread inserted with a bidirectional threaded rod 204, the arc surface of the bidirectional threaded rod 204 is threadedly connected with two movable plates 205, the surface close to the placement plate 202 is fixedly connected with a slide rail 206, the inner surface of the slide rail 206 is slidably connected with two short rods 207, and one end of the short rod 207 is fixedly connected to the movable plate 205. The bidirectional threaded rod 204 is rotated to rotate in the placement plate 202, and the bidirectional threaded rod 204 drives the moving plate 205 to move, and the moving plate 205 drives the short rod 207 to slide on the inner surface of the slide rail 206, so as to avoid the situation that the moving plate 205 rotates with the rotation of the bidirectional threaded rod 204, thereby improving the stability of the device. A handle 208 is fixedly connected to one end of the bidirectional threaded rod 204, and the size of the short rod 207 is adapted to the size of the inner surface of the slide rail 206. The handle 208 is rotated to drive the bidirectional threaded rod 204 to rotate in the connecting plate 203, and the bidirectional threaded rod 204 drives the moving plate 205 to move, so that the staff can stably rotate the bidirectional threaded rod 204 and accurately control the position of the moving plate 205. The two sides of the two moving plates 205 close to each other are fixedly connected with a protective pad 209, and the material of the protective pad 209 is rubber. The moving plate 205 drives the protective pad 209 to move, so as to avoid scratches on the surface of the test piece during the placement process. A setting plate 210 is fixedly connected to the side of the placement plate 202 close to the slide rail 206, and a push plate 211 is slidably inserted in the setting plate 210. The push plate 211 is pushed to slide in the setting plate 210, so that the staff can quickly take out the test piece, which improves the convenience of the device.

[0032] Reference Figure 4 and Figure 5As shown, specifically, the auxiliary device 3 includes a long plate 31, which is slidably connected to the inner surface of the slide groove of the fixed plate 201, one side of the long plate 31 is fixedly connected to the placement plate 202, the surface of the long plate 31 is fixedly connected to the mounting plate 32, the surface of the mounting plate 32 is provided with a limiting groove, the surface of the fixed plate 201 is fixedly connected to the short plate 33, an insert plate 34 is slidably inserted in the short plate 33, one side of the insert plate 34 is fixedly connected to an elliptical plate 35, and a side of the elliptical plate 35 close to the short plate 33 is fixedly connected to a spring 36, and one end of the spring 36 is fixedly connected to the short plate 33 and a side close to the elliptical plate 35.

[0033] Working principle: when the staff needs to position the test piece, the two-way threaded rod 204 is driven to rotate in the connecting plate 203 by turning the handle 208, and the two-way threaded rod 204 drives the two movable plates 205 to move, and the movable plate 205 drives the short rod 207 to slide on the inner surface of the slide rail 206, so as to avoid the movable plate 205 rotating with the rotation of the two-way threaded rod 204, and the movable plate 205 drives the protective pad 209 to move. When it is adjusted to an appropriate position, the test piece is placed for testing. When the test piece needs to be taken out, the push plate 211 is pushed to slide in the setting plate 210, and the push plate 211 drives the test piece to move, so as to achieve the effect of quickly positioning the test piece on the fixture body 1, and avoids the need for the staff to repeatedly move the test piece on the surface of the placement plate 202 for alignment when testing the test piece, which makes the testing process more cumbersome and time-consuming and prone to operating errors, thereby improving the practicality of the device.

[0034] When the staff needs to place the test piece, the mounting plate 32 is pushed to drive the long plate 31 to slide on the inner surface of the sliding groove of the fixed plate 201, and the long plate 31 drives the placement plate 202 to move, the mounting plate 32 is squeezed with the plug plate 34, and the plug plate 34 slides in the short plate 33. At this time, the spring 36 is in a stretched state until the plug plate 34 is aligned with the limiting groove of the mounting plate 32. The elastic force of the spring 36 drives the plug plate 34 to slide in the short plate 33 and automatically insert into the limiting groove of the mounting plate 32, thereby achieving the effect of moving the placement plate 202, avoiding the collision and damage of the fixture body 1 during the placement or removal of the test piece by the staff, and improving the stability of the device.
