[0028] In this embodiment, when the product is conveyed on the conveyor belt 2, the position of the splint 3 is first adjusted, and the splint 3 pulls the second limit plate 6 during movement, so that the second limit plate 6 moves with the movement of the splint 3, and the second limit plate 6 drives the first limit plate 5 to rotate accordingly during the movement. At the same time, with the cooperation of the elastic component 9, it is convenient to drive the second limit plate 6 to be reset when the splint 3 is reset. Since the end of the first limit plate 5 is located at the side position of the conveyor belt 2, the product can be limited and guided with the cooperation of the splint 3, the first limit plate 5 and the second limit plate 6, so as to avoid interference caused by the product being conveyed to the rear of the splint 3, facilitate the transportation of the product, and improve the transportation efficiency of the product.

[0029] In a further embodiment, Figure 1-2 As shown, the sliding assembly 8 includes a first sliding block 81 fixedly arranged on both sides of the second limiting plate 6, and both sides of the inner wall of the through groove 7 are provided with a first sliding groove 82 for the first sliding block 81 to slide, and the elastic assembly 9 includes a support rod 91 fixedly arranged on the inner wall of the through groove 7 and interlaced with the second limiting plate 6, and the outer wall of the support rod 91 is sleeved with a support plate 92, and a spring 93 is fixed on one side of the support plate 92, and a connecting frame 94 fixed to the spring 93 is fixed on one side of the second limiting plate 6.

[0030] When the clamping plate 3 is moved, the second limiting plate 6 is driven to move, so that the second limiting plate 6 is pulled out of the through slot 7. Under the cooperation of the first slider 81 and the first slide slot 82, the second limiting plate 6 is kept stable. At the same time, the second limiting plate 6 drives the movement of the connecting frame 94, and the connecting frame 94 stretches the spring 93. During the movement of the second limiting plate 6, the first limiting plate 5 is driven to rotate on the fixed plate 4, so that the first limiting plate 5 and the second limiting plate 6 can move with the movement of the clamping plate 3. Thereby, under the cooperation of the first limiting plate 5, the second limiting plate 6 and the clamping plate 3, the product is limited and guided, avoiding interference caused by the product being transported to the rear of the clamping plate 3, and facilitating the transportation of the product. When the clamping plate 3 is reset, at this time, under the elastic action of the spring 93, the movement of the connecting frame 94 is driven, and the connecting frame 94 drives the second limiting plate 6 to be retracted into the through slot 7, facilitating the movement and reset of the second limiting plate 6.
