Limiting blocks 3207 are fixedly installed on the surface of the connecting blocks 3205. The surface of the limiting blocks 3207 is slidably connected to the inner cavity of the connecting grooves 3206. By sliding the connecting blocks 3205 to the inside of the connecting grooves 3206 and by using the limiting blocks 3207 to prevent the connecting blocks 3205 from separating from the connecting grooves 3206, the position of the slide table 32 is effectively stabilized, and the slide table 32 is prevented from shifting, so as to ensure the stability of the position of the slide table 32 and thus the stability of the position of the triangular seat 2.

[0031] Reference Figure 3 and Figure 4 The latching assembly 34 includes a rod groove 3401 formed inside the triangular base 2. A spring 3402 is fixedly connected inside the rod groove 3401. One end of the spring 3402 is fixedly connected to a latching rod 3403. One end of the latching rod 3403 passes through the rod groove 3401 and is slidably connected to the inner cavity of the rod groove 3401. A latching groove 3404 is formed on the surface of the connecting rod 33. The latching rod 3403 cooperates with the latching groove 3404. When the connecting rod 33 extends into the interior of the triangular base 2, the latching rod 3403... The compression of 3 causes the locking rod 3403 to enter the inside of the rod groove 3401. When the groove 3404 moves to the position of the locking rod 3403, the locking rod 3403 is reset by the support of the spring 3402, so that one end of the locking rod 3403 is inserted into the inside of the groove 3404. Thus, the locking rod 3403 supports the position of the connecting rod 33 through the groove 3404, so as to stabilize the connecting rod 33 inside the triangular seat 2 and prevent the connecting rod 33 from separating from the triangular seat 2 and affecting the position of the triangular seat 2.

[0032] Reference Figure 4 A first support block 3405 is fixedly installed on the surface of the lever 3403, and a first support groove 3406 is opened on the inner wall of the lever groove 3401. The surface of the first support block 3405 is slidably connected to the inner cavity of the first support groove 3406. By sliding the surface of the first support block 3405 to the inner cavity of the first support groove 3406, the position of the lever 3403 is effectively stabilized, and the lever 3403 is prevented from shifting or falling off, which would affect the use effect of the lever 3403.

[0033] Reference Figure 4 and Figure 5A push rod 3407 is slidably connected to one side of the triangular base 2. One end of the push rod 3407 passes through the triangular base 2 and is slidably connected to the inner cavity of the triangular base 2. One end of the push rod 3407 is used in conjunction with the locking rod 3403. An opening 3408 is provided at the top of the connecting rod 33, and the opening 3408 is used in conjunction with the push rod 3407. A second support block 3409 is fixedly installed on the surface of the push rod 3407. A second support groove 3410 is provided in the inner cavity of the base frame 31. The surface of the second support block 3409 is connected to the second support rod 3407. The inner cavity of the support groove 3410 is slidably connected; by pushing the push rod 3407 and stabilizing the position of the push rod 3407 through the second support block 3409 and the second support groove 3410, the push rod 3407 can be pushed out of the slot 3404, and then the triangular seat 2 can be pulled upward so that the push rod 3407 can be separated from the connecting rod 33 through the opening 3408, making it easier to remove the triangular seat 2 and making it more convenient to disassemble the triangular seat 2.

[0034] Working principle: When installing the triangular base 2 and the settling plate body 4, place the settling plate body 4 in the triangular base 2, then attach the triangular base 2 to the settling plate ring 1, and insert the connecting rod 33 into the triangular base 2. Then press the triangular base 2 towards the settling plate ring 1. The compression of the connecting rod 33 causes the locking rod 3403 to enter the rod groove 3401. When the groove 3404 moves to the position of the locking rod 3403, the spring 3402 supports and resets the locking rod 3403. The connecting rod 33 is inserted into the slot 3404, thereby stabilizing the connecting rod 33 inside the triangular seat 2, thus fixing the triangular seat 2 onto the settling plate ring 1, and completing the installation of the triangular seat 2 and the settling plate body 4. Then, the second screw 3203 is rotated, and the position of the second screw 3203 is stabilized by the positioning block 3204, so that the second screw 3203 drives the slider 3201 to slide inside the slide groove 3202. The slider 3201 drives the slide table 32 to move, and the connecting block is stabilized by the limiting block 3207. The position of 3205 inside the connecting groove 3206 stabilizes the position of the sliding table 32, allowing the sliding table 32 to move the triangular seat 2 via the connecting rod 33. This adjusts the position of the triangular seat 2, providing coarse adjustment for the settling plate body 4. Rotating the first screw 21 moves the adjusting rod 22, which in turn moves the settling plate body 4, allowing for fine adjustment of its position. This ensures the accuracy of the settling plate body 4's position. When disassembling the triangular seat 2 and the settling plate body 4, push the push rod 3407 and stabilize the position of the push rod 3407 through the second support block 3409 and the second support groove 3410 to prevent the push rod 3407 from shifting. Then, push the rod 3403 out of the groove 3404 through the push rod 3407. Then pull the triangular seat 2 upward so that the push rod 3407 separates from the connecting rod 33 through the opening 3408, which makes it easier to remove the triangular seat 2 and make the disassembly of the triangular seat 2 and the settling plate body 4 more convenient.
