Optionally, with continued reference to fig. 2, the first clamping plate 1021 is tapered, and a height of a first end of the first clamping plate 1021 is less than a height of a second end of the first clamping plate 1021; the first end of the first clamping plate 1021 is the end of the first clamping plate 1021 close to the transmission line L1, and the second end of the first clamping plate 1021 is the end of the first clamping plate far away from the transmission line L1; the second clamping plate 1022 has a tapered shape, and a first end of the second clamping plate 1022 has a height smaller than a second end of the second clamping plate 1022; the first end of the second clamping plate 1022 is the end of the second clamping plate 1022 close to the transmission line L1, and the second end of the second clamping plate 1022 is the end of the second clamping plate 1022 far away from the transmission line L1.
Specifically, the first clamping plate 1021 and the second clamping plate 1022 are tapered, and the heights of the ends of the first clamping plate 1021 and the second clamping plate 1022, which are close to the transmission line L1, are smaller, i.e., the heights of the first clamping plate 1021 and the second clamping plate 1022 clamping the product 200 to be transmitted are smaller, so that the product 200 to be transmitted can be better clamped when the first clamping plate 1021 and the second clamping plate 1022 are subjected to pressure, thereby ensuring that the product 200 to be transmitted does not fall during transmission.
Optionally, with continued reference to fig. 2, the support block 1025 includes a first plate 1026 and a second plate 1027; the first clamping plate 1021 is connected to the first plate 1026 through the first fixing module 1023, and the first end of the first plate 1026 is higher than the second end of the first plate 1026; wherein the first end of the first plate 1026 is the end of the first plate 1026 that is proximal to the transmission line L1 and the second end of the first plate 1026 is the end of the first plate 1026 that is distal to the transmission line L1; the second clamping plate 1022 is connected to the second plate 1027 by a second fixing module 1024, and the height of the first end of the second plate 1027 is greater than the height of the second end of the second plate 1027; the first end of the second board 1027 is the end of the second board 1027 close to the transmission line L1, and the second end of the second board 1027 is the end of the second board 1027 far away from the transmission line L1.
Specifically, the first plate 1026 of the supporting block 1025 is connected to the first clamping plate 1021, and the second plate 1027 of the supporting block 1025 is connected to the second clamping plate 1022, since the heights of the first plate 1026 and the second plate 1027 near the end of the transmission line L1 are large; therefore, when the tensioning device 103 drives the chain 1011 to move to a side away from the transmission line L1, that is, the supporting block 1025 moves to a side away from the transmission line L1, the higher portion of the first plate 1026 applies pressure to the first clamping plate 1021, and at the same time, the higher portion of the second plate 1027 applies pressure to the second clamping plate 1022, and the first clamping plate 1021 and the second clamping plate 1022 further clamp the product 200 to be transmitted.

The preset value may be determined according to the actual situation, so that after the first clamping plate 1021 and the second clamping plate 1022 clamp the product 200 to be transferred, the first clamping plate 1021 and the product 200 to be transferred cannot be relatively displaced, the second clamping plate 1022 and the product 200 to be transferred cannot be relatively displaced, and the preset value is not specifically limited here.
