Further, the supporting rod is provided with an up-down lifting mechanism.
Further, a long slat is arranged below the base, and the base is supported on the long slat in a sliding connection manner.
Compared with the prior art, the invention has the following positive effects:
1. the invention is provided with a die head positioning device and an indexing mechanism, when in use, the cross at the front end of the die head rod is positioned by the die head positioning device, and the die head rod is hung on one side of the die head positioning device. The die head rod can rotate around the central axis of the die head rod as the positioning sleeve is supported in the inner hole of the bearing seat through the bearing; through the transposition mechanism, the die head rod rotates around the first pin shaft, so that the die head rod can be adjusted according to the tree grouping requirement, tree grouping can be conveniently carried out, and tree grouping efficiency is remarkably improved.
2. The supporting rod is provided with an up-down lifting mechanism, and the operation height can be adjusted.
3. The bottom of the base is provided with a long slat, the base is slidably connected and supported on the long slat, and the plane operation position can be adjusted according to the requirement.
