the utility model can be detached when the arm head is not used, is installed when the arm head is used, can realize the function of angle adjustment through the angle adjustment arm, can achieve the purpose of angle adjustment, is convenient for better adapting to the installation working condition of the hanging basket, improves the working efficiency, and can better adapt to complex working conditions.

The utility model can achieve the aim of adjusting the arm length through the extension and retraction of the connecting arm and the straight arm, avoids the phenomenon that the arm length can be adjusted only through the extension and retraction arm in the past, can achieve the aim of better adapting to working conditions, and enlarges the working range.

Drawings

Fig. 1 is a schematic structural view of the present utility model.

Fig. 2 is a schematic view of the structure of a conventional elbow arm.

In the figure: boom 1, second locating hole 2, first locating hole 3, linking arm 4, reinforcing plate 5, sector plate 6, adjustment arm 7, straight arm 8, hanging hole 9, third locating hole 10, second hanging plate 11, adjustment hole 12, pivot 13, first hanging plate 14, hanging flower basket link 15.

Description of the embodiments

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In fig. 1, a multifunctional arm head for a crane comprises a suspension arm 1 and an angle adjusting arm, wherein the angle adjusting arm is inserted into the last section of telescopic arm of the suspension arm 1, the other end of the angle adjusting arm is inserted into the arm head, a first hanging plate 14 and a second hanging plate 11 are arranged on the last section of telescopic arm and the arm head of the suspension arm 1, and a hanging basket connecting frame 15 is fixedly arranged at one end, far away from the angle adjusting arm, of the arm head.

Further, the angle adjustment arm includes the linking arm 4, the right-hand member both sides fixed mounting of linking arm 4 has the sector plate 6 that the structure is the same, two the one end that sector plate 6 kept away from linking arm 4 is along cambered surface evenly distributed has a plurality of adjustment holes 12, two the one end that sector plate 6 is close to linking arm 4 is provided with pivot 13, install the adjustment arm 7 in the pivot 13, be provided with on the adjustment arm 7 with adjustment hole 12 matched with fixed orifices, the right-hand member of adjustment arm 7 is provided with hanging hole 9.

Further, a first positioning hole 3 is formed in the last section of telescopic arm of the suspension arm 1, and second positioning holes 2 matched with the first positioning hole 3 are uniformly formed in the connecting arm 4.
