[0069] The single-phase limiting component 21 is provided below the first clamping component 51, and the tray base 1 is provided with a second clamping component 52 corresponding to the first clamping component 51, which can be clamped at a set position and released at a set position; the single-phase limiting component 21 is adjustably arranged on the tray base 1 through the first elastic extension piece 53, the first clamping component 51 and the second clamping component 52;

[0070] The three-phase limiting component 22 is provided below the first clamping component 51, and the tray base 1 is provided with a second clamping component 52 corresponding to the first clamping component 51, which can be clamped at a set position and released at a set position; the three-phase limiting component 22 is adjustably arranged on the tray base 1 through the first elastic extension piece 53, the first clamping component 51 and the second clamping component 52;

[0072] Referring to Figure 1 , Figure 2 , Figures 5 to 8 In one embodiment, the first clamping component 51 includes a fixed seat 511, a second elastic extension piece 512 and a clamping pin 513; the clamping pin 513 is arranged on the fixed seat 511 through the second elastic extension piece 512;

[0074] The fixed seat 511 can be arranged below the three-phase limiting component 22;

[0075] The fixed seat 511 can be arranged below the terminal limiting component 23.

[0076] Referring to Figure 1 , Figure 2 , Figures 5 to 8In one embodiment, the second detent assembly 52 comprises a detent 521 and a movable member 522, the detent 521 is arranged on the tray base 1 and corresponds to the position below the detent pin 513 of the first detent assembly 51, the detent 521 is used to lock the first detent assembly 51 which is arranged in a downward position by a certain distance; the movable member 522 is naturally arranged on the detent 521 and maintains a certain distance with the top of the detent 521, the first detent assembly 51 can disengage the detent 521 by continuing to move downward by a certain distance and link the movable member 522.

[0077] Referring to Figures 5 to 8 In one embodiment, the front end of the detent pin 513 is a three-dimensional body with an inclined surface; the top flange of the detent 521 has a smooth curved upper surface; and the top flange of the detent 521 has a flat lower surface. When the target floating limiting assembly 2 is pressed downward by a person, the first detent assembly 51 moves downward, the inclined surface first contacts the top flange upper surface of the detent 521; as the downward movement continues, the detent pin 513 gradually compresses the second elastic member 512 due to the contact between the inclined surface and the top flange upper surface of the detent 521, until the detent pin 513 passes the top flange upper surface of the detent 521 and loses the contact with the top flange upper surface, the detent pin 513 will be elongated along its axis under the elastic force of the second elastic member 512; at this time, the person removes the downward external force on the target floating limiting assembly 2, the target floating limiting assembly 2 is affected by the upward force of the first elastic member 53, the detent pin 513 of the first detent assembly 51 abuts against the top flange lower surface of the detent 521, achieving the purpose of locking the target floating limiting assembly 2 at a certain position, i.e. achieving the purpose of “pressing the target floating limiting assembly → the self-locking of the pressing type adjusting mechanism as the downward movement → the upper surface of the floating limiting assembly being flush with the surface of the tray cavity”.

[0078] Referring to Figures 5 to 8In one embodiment, the movable part 522 movably covers the clamping part 521 (coaxially arranged), initially, the movable part 522 is kept at a set distance from the top flange of the clamping part 521; the upper surface of the flange of the movable part 522 is flat and can be in contact with the lower surface of the top flange of the clamping part 521; the lower surface of the flange of the movable part 522 is a smooth arc surface; this series of designs can facilitate the linkage of the clamping pin 513 and the movable part 522 to disengage the clamping part 521 from the first clamping assembly 51; when the self-locking of the press-type adjusting mechanism 5 needs to be disengaged, the target floating limiting assembly 2 is pressed downward by hand, at this time, the first clamping assembly 51 also continues to move downward; with the downward movement, the inclined surface of the clamping pin 513 is in temporary contact with the edge of the flange of the movable part 522, under the action of the contact between the inclined surface and the edge of the flange of the movable part 522, the clamping pin 513 is compressed by the second elastic part 512, and after passing the edge of the flange of the movable part 522, with the deepening of the continuous downward movement, the clamping pin 513 moves to the depth position of the arc surface of the movable part 523, under the action of the elastic force of the second elastic part 512, the clamping pin 513 is elongated along the axis by a small amount, and therefore, the front end of the clamping pin 513 abuts against the lower side of the flange of the movable part 522; then, the downward force on the target floating limiting assembly 2 is removed by hand, and under the influence of the upward force of the first elastic part 53, the target floating limiting assembly 2 moves upward, at this time, it drives the first clamping assembly 51 to move upward, and then, the first clamping assembly 51 drives the movable part 522 to move upward together, and moves upward to the set position, the upper surface of the flange of the movable part 522 is in flat contact with the lower surface of the top flange of the clamping part 521, at this time, the movable part 522 can no longer move upward, and the first clamping assembly 51 cannot move the movable part 522 and moves upward along the arc surface of the flange of the movable part 522, in the process, the clamping pin 513 temporarily compresses the second elastic part 512, and after passing the movable part 522, the movable part 522 loses the abutting action of the clamping pin 513 and falls to the original initial position, while the first clamping assembly 51 continues to move upward, the inclined surface temporarily contacts the upper surface of the top flange of the clamping part 521, at this time, the clamping pin 513 is slightly elongated and restored, and after completely passing the top flange of the clamping part 521, the second elastic part 512 restores the clamping pin 513 to the natural elongated state, thereby disengaging the self-locking of the press-type adjusting mechanism 5 and achieving the "upward convex" reset of the target floating assembly 2, that is, the state of the floating limiting assembly 2 convexly above the tray cavity 15 is the initial state of the floating limiting assembly 2.
