The fork 13 has more types according to different application ranges, and the left side and the right side of the front part of the fork rod are removed to form a triangle, so that the upper cross section is hexagonal; and the lower part removes a triangle, so that the side cross section is a pentagon.
A clamp 12 matched with the pallet fork 13 for use is arranged above the pallet fork 13, and a semi-automatic connecting rod adjusting structure is connected between the clamp 12 and the corresponding inner and outer fixed plates 4 and 7;
the semi-automatic connecting rod adjusting structure comprises a pair of symmetrically arranged triangular plates 8, one sides of the short edges of the two triangular plates 8 are hinged to a pin shaft II 6, the other sides of the short edges of the two triangular plates 8 are hinged to the upper portion of an oil cylinder 19 through a pin shaft I5, and one sides of the long edges of the two triangular plates 8 are hinged to a connecting rod 10 through a pin shaft III 9. The lower part of the oil cylinder 19 is hinged on the pin shaft VII 20. The bush 11 comprises two triangular blocks which are symmetrically arranged, and the two triangular blocks are symmetrically welded on the clamp 12 by the central planes of the inner fixing plate 4 and the outer fixing plate 7; and a pin shaft IV 15 and a limiting pin are fixed between the two triangular blocks, and the limiting pin is positioned above the pin shaft IV 15.

the present embodiment illustrates the movement of the mechanism by first sliding the connecting rod 10;
first, as shown in FIG. 3, the tongs are now in the lowest horizontal position. When the oil cylinder contracts, the oil cylinder drives the triangular plate 8 to rotate anticlockwise along the pin shaft II 6 through the pin shaft I5, and the triangular plate drives the connecting rod 10 to lift through the pin shaft III 9. The connecting rod 10 acts on the bush through the pin shaft IV 15, the bush drives the clamp, and the clamp firstly slides vertically upwards. At this time, the machine can clamp cylindrical materials with different specifications due to the change of the distance between the clamp 12 and the pallet fork 13;
secondly, as shown in fig. 4, the clamp is lifted to the horizontal highest position along with the contraction of the oil cylinder, and the machine can shovel some light materials or a box body with lower height;
with the further contraction of the oil cylinder, the clamp rotates along the pin shaft V17, when the oil cylinder contracts to the shortest length, as shown in fig. 5, the clamp rotates to the vertical position, and at the moment, the machine can shovel more materials or a higher box body.
The present invention has been described above by way of example, but the present invention is not limited to the above-described specific embodiments, and any modification or variation made based on the present invention is within the scope of the present invention as claimed.
