The relative sliding of the sliding rail 12 and the fixed rail 11 realizes the relative sliding of the probe assembly and the mounting bracket 200, which is convenient for the maintenance personnel to maintain the adjustable probe module in the later period, reduces the configuration of the maintenance personnel, reduces the maintenance cost, and the fixed rail 11 in the application is connected to the mounting bracket 200 through the first mounting portion 111. The first mounting portion 111 is formed by bending the top of the fixed rail 11, which can be quickly and conveniently mounted. Compared with the prior art, the adapter plate 300 is needed between the mounting bracket 200 and the fixed rail 11, the adapter plate 300 is connected to the mounting bracket 200 and the fixed rail 11 respectively, and the pull-out structure is mounted on the mounting bracket 200. The design of the first mounting portion 111 in the application can omit the adapter plate 300, reduce the production cost, simplify the mounting steps, and achieve the technical effect of reducing cost and increasing efficiency.
[0044] In some embodiments, the first mounting portion 111 has a mounting hole 1111; the pull-out structure 100 further comprises a fastener which penetrates the mounting hole 1111 and is used for being connected to the bottom of the mounting bracket 200.

[0048] In some embodiments, referring to Figure 4 The second mounting portion 121 is located at the bottom of the sliding support 2.
[0049] Specifically, the second mounting portion 121 is connected with the sliding support 2 from the bottom of the sliding support 2. The second mounting portion 121 not only has a connecting and fixing effect, but also has a certain supporting effect on the sliding support 2. Compared with connecting and fixing the sliding support 2 from the side, the second mounting portion 121 can directly bear the gravity of the sliding support 2 from the bottom, avoiding deformation of the connection between the sliding support 2 and the sliding rail 12 due to the gravity of the sliding support 2, and improving the service life of the pull-out structure 100.
[0050] In some embodiments, referring to Figure 4 The pull-out structure 100 further includes a connecting piece 13 located between the sliding rail 12 and the sliding support 2. The connecting piece 13 is arranged along two sides of the second horizontal direction b and connected with the sliding rail 12 and the sliding support 2, respectively.
[0051] Specifically, the connecting piece 13 can be a plate body. The sliding rail 12 can be connected with the sliding support 2 through the connecting piece 13, or through the second mounting portion 121, or through the connecting piece 13 and the second mounting portion 121 together. The sliding rail 12 is connected with the sliding support 2 through the connecting piece 13 and the second mounting portion 121 together, which can simultaneously connect the bottom of the sliding support 2 and the side of the sliding support 2, so that the connection between the sliding rail 12 and the sliding support 2 is more stable and reliable.
[0052] In some embodiments, referring to Figure 4 The fixed rail 11 is provided with a sliding groove piece 112, the sliding groove piece 112 is formed with a sliding groove 1121, the sliding groove 1121 extends along the first horizontal direction a, and the sliding rail 12 is provided with a sliding block 122, the sliding block 122 is slidingly arranged in the sliding groove 1121.

The sliding groove 1121 extends along the first horizontal direction a, and the sliding block 122 can slide along the first horizontal direction a in the sliding groove 1121, so that the sliding rail 12 can slide relative to the fixed rail 11 along the first horizontal direction a.
[0054] In some embodiments, referring to Figure 2 , the number of guide rails 1 is two, and the two guide rails 1 are arranged opposite to each other along the second horizontal direction b. The sliding bracket 2 is arranged between the two guide rails 1, and the sliding bracket 2 is connected to the sliding rail 12 of the corresponding guide rail 1 on the two sides arranged along the second horizontal direction b.

[0056] Specifically, the two guide rails 1 are arranged opposite to each other along the second horizontal direction b, so that there is one guide rail 1 on each side of the sliding bracket 2 along the second horizontal direction b. The sliding bracket 2 is connected to the sliding rail 12 on each of the two sides arranged along the second horizontal direction b, so that the two sides of the sliding rail 12 can be uniformly stressed, and the service life of the pull-out structure 100 is improved.
[0057] In some embodiments, referring to Figure 2 , the pull-out structure 100 further comprises two limiting pieces 3, and the two limiting pieces 3 are arranged on the mounting bracket 200 in a detachable manner. The two limiting pieces 3 are arranged at intervals along the first horizontal direction a, and the sliding bracket 2 is located between the two limiting pieces 3.
[0058] The limiting piece 3 is located on the sliding path of the sliding bracket 2.
[0059] Specifically, the limiting piece 3 can be a baffle or a fixed block. The two limiting pieces 3 can limit the sliding bracket 2 to a specified position, provide positioning for the sliding bracket 2, and avoid free sliding of the sliding bracket 2, which affects the normal work of the probe assembly and other components arranged on the sliding bracket 2. The limiting piece 3 is detachably arranged, and after one limiting piece 3 is detached, the sliding bracket 2 can be pulled out for maintenance of the probe assembly.
[0060] In some embodiments, referring to Figure 5 , the first mounting portion 111 is in the shape of a long strip extending along the first horizontal direction a, and the first mounting portion 111 has a weight-reducing gap 1112 to divide the first mounting portion 111 into at least two sections.
[0061] Specifically, the first mounting portion 111 in the shape of a long strip can increase the mounting area between the fixed rail 11 and the mounting bracket 200, and ensure stable connection between the fixed rail 11 and the mounting bracket 200.
[0062] The weight-reducing gap 1112 is arranged on the first mounting portion 111, which can appropriately reduce the weight of the pull structure 100, reduce the load of the mounting bracket 200, and improve the service life of the overall device.
