Wherein, the transmission assembly 103 is located between the two rocker lifting mechanisms 1021 of the lifting assembly 102, the transmission assembly 103 includes an eccentric part 1031, a first connecting rod 1032 and a second connecting rod 1033. By driving the eccentric part 1031 to rotate through the driving assembly 104, the eccentric part 1031 drives the second connecting rod 1033 to move, the second connecting rod 1033 drives the first connecting rod 1032 to move at the same time, thereby driving the free ends g21 and g22 of the rocker lifting mechanisms 1021 connected with the first connecting rod 1032 and the second connecting rod 1033 to change positions, so that the lifting base 105 hinged to the fixed ends g11 and g12 of the rocker lifting mechanisms 1021 reciprocatingly lifts relative to the mounting base 101. The connection structure of the lifting device 100 is simple, the transmission is stable, the assembly difficulty is small, which is beneficial to the production enterprises to reduce production cost, improve production efficiency and reduce equipment failure rate.

[0057] Please refer to Figure 1 , Figure 2 and Figure 3The number of the first connecting rods 1032 and the number of the second connecting rods 1033 in the transmission assembly 103 are both two, the two first connecting rods 1032 are oppositely arranged along a second direction E2, the second direction E2 is perpendicular to the first direction E1, the two second connecting rods 1033 are adjacently arranged with the two first connecting rods 1032 respectively, and the two ends of any one first connecting rod 1032 are hingedly connected with the two rocker lifting mechanisms 1021 respectively. One end of each of the two second connecting rods 1033 is connected with the eccentric member 1031, and the other end of each of the two second connecting rods 1033 is hingedly connected with the two rocker lifting mechanisms 1021 respectively, that is, the two ends of one of the two second connecting rods 1033 are hingedly connected with the eccentric member 1031 and one of the two rocker lifting mechanisms 1021 respectively, and the two ends of the other of the two second connecting rods 1033 are hingedly connected with the eccentric member 1031 and the other of the two rocker lifting mechanisms 1021 respectively. The two first connecting rods 1032 and the two second connecting rods 1033 can correspond to each other, and the second connecting rod 1033 is adjacently arranged with the corresponding first connecting rod 1032.

[0058] For example, any one lifting assembly 102 has a first free end g21 and a second free end g22, one end of any one first connecting rod 1032 is hingedly connected with the first free end g21 of one of the two rocker lifting mechanisms 1021, and the other end is hingedly connected with the second free end g22 of the other of the two rocker lifting mechanisms 1021; the two ends of one of the two second connecting rods 1033 are hingedly connected with the eccentric member 1031 and the second free end g22 of one of the two rocker lifting mechanisms 1021 respectively, and the two ends of the other of the two second connecting rods 1033 are hingedly connected with the eccentric member 1031 and the second free end g22 of the other of the two rocker lifting mechanisms 1021 respectively.

[0059] For example, in the transmission process of a set of first connecting rods 1032 and second connecting rods 1033, when the driving assembly 104 drives the eccentric part 1031 to rotate, the eccentric part 1031 can drive the second connecting rod 1033 to move along the first direction E1, and the second connecting rod 1033 drives the second free end g22 of the rocker lifting mechanism 1021 to move along the first direction E1, and at the same time, the second free end g22 of the rocker lifting mechanism 1021 drives the first free end g21 of the other lifting mechanism to move along the first direction E1 through the first connecting rod 1032. The movement direction of another set of first connecting rods 1032 and second connecting rods 1033 is the same as that of the above-mentioned set of first connecting rods 1032 and second connecting rods 1033 and is opposite to that of the above-mentioned set of first connecting rods 1032 and second connecting rods 1033. In this way, by driving the eccentric part 1031 to rotate through the driving assembly 104, the eccentric part 1031 drives two second connecting rods 1033 to move, and the two second connecting rods 1033 drive two first connecting rods 1032 to move at the same time, so as to change the positions of the two free ends g21 and g22 of the rocker lifting mechanism 1021 connected with the first connecting rod 1032 and the second connecting rod 1033 through linkage, so as to make the lifting base 105 hinged to the fixed end g12 of the rocker lifting mechanism 1021 displace upward and downward relative to the mounting base 101. In this way, the connection stability of the transmission assembly 103 and the lifting assembly 102 can be improved, and the whole structure can be lifted more stably.

In this way, the first connecting rod 1032 can connect two lifting assemblies 102 and can drive the two lifting assemblies 102 to move synchronously through linkage, and the structural strength and the structural stability of the transmission assembly 103 can be improved.

[0061] In an alternative implementation manner, the first connecting rod 1032 can include a frame k1 and a reinforcing rib k2, both ends of the frame k1 are respectively hinged to the two rocker lifting mechanisms 1021, and the reinforcing rib k2 is fixedly connected to the inner side of the frame k1. Since the length of the first connecting rod 1032 is greater than that of the second connecting rod 1033, the reinforcing rib k2 arranged in the first connecting rod 1032 can enhance the strength of the first connecting rod 1032, so as to enhance the overall stability of the transmission assembly 103. The frame k1 can be rhombic, and the number of the reinforcing ribs k2 can be one, two, three or more.

[0062] Please refer to Figure 5 , Figure 5 is another structure schematic view of the lifting assembly 102 and the transmission assembly 103 provided by the embodiment of the utility model, in an alternative implementation, two second connecting rods 1033 in any one transmission assembly 103 can be located between two first connecting rods 1032, two second connecting rods 1033 are arranged between two first connecting rods 1032, can reduce the distance between two second connecting rods 1033, thereby reducing the size of eccentric member 1031 connected with two second connecting rods 1033, further improve the connection stability of two second connecting rods 1033 and eccentric member 1031.

Third swing arm b3 can be hinged with mounting base 101, fourth swing arm b4 can be hinged with lifting base 105, and the end of third swing arm b3 away from mounting base 101 can be hinged with the end of fourth swing arm b4 away from lifting base 105 with second rotation axis z2, and second rotation axis z2 is hinged with the other first connecting rod 1032 of the two first connecting rods 1032 and one second connecting rod 1033. First rotation axis z1 can connect one first connecting rod 1032, second rotation axis z2 can connect the first connecting rod 1032 and one second connecting rod 1033, so when driving assembly 104 drives second connecting rod 1033 to move through eccentric part 1031, second connecting rod 1033 can drive third swing arm b3 and fourth swing arm b4 to swing through second rotation axis z2, and drive first connecting rod 1032 to move through second rotation axis z2, so that first connecting rod 1032 can drive first swing arm b1 and second swing arm b2 to swing synchronously through first rotation axis z1.

[0066] Exemplarily, since second rotation axis z2 can be connected with one first connecting rod 1032 and one second connecting rod 1033, and first rotation axis z1 is connected with one first connecting rod 1032, the length of second rotation axis z2 is greater than that of first rotation axis z1.
