[0052] In the embodiment of the present application, the rack body 100 as the main bearing component can be provided as a frame structure to reduce the self-weight, thereby reducing the bearing pressure of the conveying system, while having good structural strength, being able to provide good bearing capacity, and being relatively simple to manufacture, thereby being able to reduce the manufacturing cost.

[0053] In some optional embodiments, reference can be made to Figure 1 、 Figure 4 and Figure 5 together, the first connecting member 103 and the second connecting member 104 are both configured as a circular shaft connecting rod.

[0054] In the embodiment of the present application, the circular shaft connecting rod structure is simple, easy to manufacture and maintain, which helps to reduce the production cost and maintenance difficulty.

[0055] In some optional embodiments, reference can be made to Figure 1 , the first connecting member 103 is connected with the fourth end through a first grooved wheel structure 109, wherein the fourth end is provided with a first sliding groove 1011 adapted to slidingly match the first grooved wheel structure 109.

[0056] In the embodiments of the present application, the mechanical movement guide structure is formed by the cooperation of the sliding groove and the groove wheel, so that the first connecting piece 103 can slide along a fixed track when transmitting power, which can eliminate the movement dead point of the traditional hinged structure, for example, when the driving piece rotates, the sliding groove can compensate for the slight angular deviation in the movement of the connecting piece, avoiding the phenomenon of jamming; on the other hand, the constraint action of the sliding groove makes the rotational movement of the two driving pieces form a forced synchronization mechanism, ensuring that the swing angles of the first clamping jaw 107 and the second clamping jaw 108 have a small difference.

[0057] In some optional embodiments, referring to Figure 1 and Figure 6 together, the first groove wheel structure 109 includes a first groove wheel shaft 1091, a first baffle disc 1092 and a second baffle disc 1093; the first groove wheel shaft 1091 is rotationally connected with the first connecting piece 103 and penetrates the first sliding groove 1011, that is, the first groove wheel shaft 1091 can rotate on the first connecting piece 103 about its own axis, and the first groove wheel shaft 1091 can slide in the first sliding groove 1011 along the length direction of the first sliding groove 1011; the first baffle disc 1092 is connected with the first groove wheel shaft 1091, and the first baffle disc 1092 can be designed as a disc, and the first baffle disc 1092 can be coaxially connected at the axial end of the first groove wheel shaft 1091; the second baffle disc 1093 is connected with the first groove wheel shaft 1091, and the second baffle disc 1093 can also be designed as a disc, and the thickness of the second baffle disc 1093 can be consistent or inconsistent with the thickness of the first baffle disc 1092, and the second baffle disc 1093 is coaxially sleeved on the first groove wheel shaft 1091, wherein necessary shaft shoulders can be designed on the first groove wheel shaft 1091 to form axial limiting for the second baffle disc 1093, and a first annular groove suitable for cooperating with the first sliding groove 1011 is formed between the first baffle disc 1092 and the second baffle disc 1093, that is, in the central axis direction of the first driving piece 101, the first baffle disc 1092 and the second baffle disc 1093 are respectively located on both sides of the first driving piece 101, and the first baffle disc 1092, the second baffle disc 1093 and the first driving piece 101 respectively have a spacing therebetween.

[0058] In the embodiments of the present application, through the setting of the first baffle disc 1092 and the second baffle disc 1093, the first groove wheel shaft 1091 can be prevented from having large axial movement, and the transmission reliability of the first connecting piece 103 can be ensured.

[0059] In some optional embodiments, referring to Figure 6 , the first groove wheel shaft 1091 is matched with a first bearing 1094 to slide with the first sliding groove 1011 through the first bearing 1094; the number of the first bearing 1094 can be configured as two, and the two first bearings 1094 are isolated by a shaft baffle 115.

[0060] In the embodiment of the present application, the diameter of the first bearing 1094 is slightly smaller than the slot width of the first sliding slot 1011, that is, the first bearing 1094 is in contact with one of the slot walls of the first sliding slot 1011, and the rolling friction is formed between the first bearing 1094 and the slot wall of the first sliding slot 1011. Compared with directly matching the first slot wheel shaft 1091 with the first sliding slot 1011, the wear can be reduced and the service life can be prolonged.

[0062] In the embodiment of the present application, the second connecting piece 104 forms a bidirectional motion constraint structure through the cooperation of the second slot wheel structure 110 and the second sliding slot 1021. When the second connecting piece 104 performs a clamping action, it can not only accurately translate in the direction of the sliding slot, but also automatically compensate for the angular deviation by means of the self-rotation of the slot wheel. In cooperation with the matching structure of the first connecting piece 103 and the first sliding slot 1011, the first clamping jaw 107 and the second clamping jaw 108 can have higher positioning accuracy, so as to realize accurate control of the clamping action of the clamping device.

The third baffle disc 1102 is connected with the second grooved wheel shaft 1101, and the third baffle disc 1102 can be designed as a disc and can be coaxially connected with the shaft end of the second grooved wheel shaft 1101. The fourth baffle disc 1103 is connected with the second grooved wheel shaft 1101, and the fourth baffle disc 1103 can also be designed as a disc, and the thickness of the fourth baffle disc 1103 can be consistent with or inconsistent with the thickness of the third baffle disc 1102. The fourth baffle disc 1103 is coaxially sleeved on the second grooved wheel shaft 1101, wherein necessary shaft shoulders can be designed on the second grooved wheel shaft 1101 to axially limit the fourth baffle disc 1103.
