Detailed Description

Referring to fig. 1, a clamp for grabbing an aluminum bar includes a clamping portion 10 and a lifting portion 20, where the clamping portion 10 includes a main shaft 11 and two clamping arm sets, the two clamping arm sets are respectively referred to as a first clamping arm set 101 and a second clamping arm set 102, each clamping arm set includes two first clamping arms 12 and two second clamping arms 13 crossed together in an X-shape, the first clamping arms 12 and the second clamping arms 13 are both hinged to the main shaft 11, the first clamping arms and the second clamping arms are both arranged along an oblique direction, the first clamping arms and the second clamping arms can rotate relative to the main shaft 11, so that an included angle between the first clamping arms and the second clamping arms is increased or decreased, and lower ends of the first clamping arms and the second clamping arms are both formed into clamping jaws 14. Specifically, in this embodiment, the lower end of the first clamping arm is bent toward the second clamping arm to form the clamping jaw, and the lower end of the second clamping arm is bent toward the first clamping arm to form the clamping jaw. The clamping jaw is used for clamping two sides of the aluminum bar 90 in the radial direction, when the clamping jaw is clamped on two sides of the aluminum bar in the radial direction, the clamping jaws on the two first clamping arms are located on one side of the aluminum bar, and the clamping jaws on the two second clamping arms are located on the other side of the aluminum bar.

The lifting part 20 comprises a boom 21 and two boom groups, which are respectively referred to as a first boom group 201 and a second boom group 202, the first boom group 201 corresponding to the first clamp arm group 101, and the second boom group 202 corresponding to the second clamp arm group 102, i.e. one clamp arm group for each boom group.
