Thus, the first beam 224 and the second beam 225 are located on both sides of the lifting beam 221, and the lifting beam 221 is located between the second connecting rod 227 and the third connecting rod 228. The two ends of the first connecting rod 226 are connected to the first beam 224 and the second beam 225, respectively, and the two ends of the second connecting rod 227 are connected to the first beam 224 and the second beam 225, respectively. The lifting beam 221 passes through the hole formed by the first beam 224, the second beam 225, the first connecting rod 226, and the second connecting rod 227, reducing the swaying between the lifting beam 221 and the hook 223. In a plane perpendicular to the first connecting rod 226, the first connecting rod 226, the second connecting rod 227, and the third connecting rod 228 are arranged in a triangle, which limits the first beam 224 (and the second beam 225).

[0070] In one embodiment, the gap between the second connecting rod 227 and the third connecting rod 228 is greater than the width of the lifting beam 221, allowing the first beam 224 (and the second beam 225) to change at a predetermined angle around the first connecting rod 226. Thus, the first beam 224 and the second beam 225 can easily change angle relative to the lifting beam 221 to accommodate different objects 6 to be transported by the hook 223.

[0071] In one embodiment, the first connecting rod 226 is fixed to the ring 222.

[0072] In one embodiment, the Z-sliding table 42 has a first notch, so that the hook 22 hanging under the carrier 21 will not collide with the Z-sliding table 42 during the process of the carrier 21 moving to the first placement position 423 (or the carrier 21 leaving the first placement position 423).

[0073] In one embodiment, the X sliding table 44 has a second notch, so that the hook 22 hanging under the carrier 21 will not collide with the X sliding table 44 during the process of the carrier 21 moving to the second placement position 443 (or the carrier 21 leaving the second placement position 443).

[0074] In one embodiment, a third notch is provided on the frame 1 so that the hook 22 hanging under the carrier 21 will not collide with the frame 1 during the movement of the carrier 21 in the first conveying channel 31.

[0075] In one embodiment, a fourth notch is provided on the frame 1 so that the hook 22 hanging under the carrier 21 will not collide with the frame 1 during the movement of the carrier 21 in the second conveying channel 32.

[0076] In one embodiment, the system further includes: a third cylinder 531 mounted on the frame 1 and having a third telescopic portion 532; the third telescopic portion 532 has a slot 5321; when the X sliding table 44 is in the fourth position, the third telescopic portion 532 extends and can engage the hook 22 in the slot 5321. Thus, when the third telescopic portion 532 of the third cylinder 531 extends, the hook 22 is engaged in the slot 5321, reducing the wobbling of the hook 22.

[0077] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
