[0018] In this implementation plan, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, the clamping adjustment assembly 2 includes a mechanical housing 201. Supports 202 are fixedly connected to the lower left side of the inner wall of the mechanical housing 201, with a ball nut 203 connected to the right-side bearing inside the support 202.

A drive motor 206 is fixedly connected to the upper-middle opening on the right side of the mechanical housing 201, and the left end of the output shaft of the drive motor 206 is connected to the right end of the worm 205 via a coupling. A lead screw 207 is threaded into the ball nut 203. The front and rear ends of the lead screw 207 pass through the front and rear sides of the interior of the machine housing 201, respectively. The front and rear ends of the lead screw 207 are fixedly connected to the connecting plates 208, and the lower middle part of the inner side of the connecting plates 208 is fixedly connected to the slide rod 209, which slides through the front and rear sides of the interior of the machine housing 201. The slide rod 209 is located on the lower side of the lead screw 207. The middle part of the inner side of the connecting plate 208 is fixedly connected to the electric push rod 210, and the outer end of the output shaft of the electric push rod 210 passes through the interior of the connecting plate 208. The outer end of the output rod of the electric push rod 210 is fixedly connected to the clamping block 211. The electric push rod 210 is located between the lead screw 207 and the slide rod 209.

[0019] In this implementation plan, in conjunction with the appendix Figure 4As shown, the alignment indicator component 3 includes a C-shaped guide rod 301. An annular groove is provided in the middle of the outer wall of the right horizontal section of the C-shaped guide rod 301, and an annular marker block 302 is embedded in the inner side of the annular groove to indicate the position of the guide rail. A sliding sleeve 303 is slidably disposed on the outer wall of the right horizontal section of the C-shaped guide rod 301, and an observation port 304 is provided in the upper middle side of the sliding sleeve 303 to indicate the position of the compartment. A telescopic rod 305 is fixedly connected to the lower middle part of the sliding sleeve 303, and a lifting plate 306 is fixedly connected to the lower end of the telescopic rod 305, wherein the telescopic rod 305 is located in the upper middle part of the lifting plate 306. A magnet block 307 is embedded in the lower middle opening inside the lifting plate 306.

[0020] In this embodiment, specifically, the middle left part of the mechanical box 201 is fixedly connected to the middle right part of the U-shaped bracket 101.

[0021] In this embodiment, specifically, one end of the C-shaped guide rod 301 is fixedly connected to the upper front part of the mechanical box 201, and the other end is fixedly connected to the upper rear part of the mechanical box 201.

[0022] In this embodiment, specifically, the annular marker block 302 is an annular PVC plastic block of a different color from the C-shaped guide rod 301, and the center point of the annular marker block 302 is directly opposite to the center point of the right surface of the U-shaped bracket 101.

[0023] In this embodiment, specifically, the thread direction on the front side of the outer wall of the double-ended threaded rod 103 is opposite to the thread direction on the rear side of its outer wall.

[0024] In this embodiment, specifically, the observation port 304 is an arc-shaped opening, through which the outer wall of the C-shaped guide rod 301 can be observed.

[0025] In this embodiment, specifically, the magnet block 307 is a neodymium iron boron magnet block.

[0026] In this embodiment, specifically, the drive motor 206 and the electric push rod 210 are electrically connected to an external control panel.

[0027] In this implementation plan, in conjunction with the appendix Figure 1-5As shown, when using this mounting fixture, the operator can first fix the fixture onto the guide rail. During fixing, the guide rail needs to be placed between the clamping plates 105. The hexagonal block 104 is then rotated using an external wrench, causing it to move inwards synchronously via the double-threaded rod 103, until the clamping plate 105 clamps the guide rail. Because the clamping plates 105 are symmetrically positioned in the inner middle of the U-shaped bracket 101, and because the double-threaded rod 103 can move the clamping plates 105 inwards synchronously, the center of the guide rail will be aligned with the center of the U-shaped bracket 101 after the clamping plate 105 clamps the guide rail. The center position of the guide rail can then be indicated by the annular marker block 302. Subsequent operations... Personnel can install this fixture onto the box body. During installation, the box body needs to be placed between the clamping blocks 211, and the electric push rod 210 is activated via the external control panel. The electric push rod 210 drives the clamping blocks 211 to move inward until the clamping blocks 211 clamp the box body. Then, the operator can measure the upper part of the box body to determine the middle position of the upper part of the box body. Then, the operator can push the sliding sleeve 303 to move, so that the sliding sleeve 303 drives the lifting plate 306 to move through the telescopic rod 305 until the lifting plate 306 moves to the middle position of the upper part of the box body. Then, the operator can extend the telescopic rod 305 until the lifting plate 306 is attracted to the middle position of the upper part of the box body by the magnet block 307. The observation port 304 is located in the middle of the sliding sleeve 303, and the telescopic rod 305 is located in the lower middle of the sliding sleeve 303. The telescopic rod 305 is also located in the upper middle of the lifting plate 306. Therefore, the middle position of the compartment can be reflected through the observation port 304. When the observation port 304 is offset relative to the annular marker block 302, the operator can start the drive motor 206 through the external control panel. The drive motor 206 drives the ball nut 203 to rotate through the worm gear 205 and worm wheel 204. The ball nut 203 then drives the lead screw 207 to move forward or backward. At this time, the connecting plate 208 will move the clamping block 211 through the electric push rod 210. Because the compartment is clamped between the clamping blocks 211, the compartment will move. During the movement of the compartment, the sliding sleeve 303 will slide on the outer wall of the C-shaped guide rod 301. When the observation port 304 coincides with the annular marker block 302, the guide rail is exactly located in the middle of the compartment. Compared with the prior art, the present invention can indicate the position of the guide rail through the annular marker block 302 and the position of the compartment through the observation port 304. Thus, during the adjustment process, the operator can clearly observe the relative position of the guide rail and the compartment without frequently measuring the relative position of the guide rail and the compartment, achieving the effect of indication and adjustment. This can effectively avoid the problem of the installation efficiency of the compartment and the guide rail being affected, making it more convenient to use.
