The inside body of rod 4 that sets up of casing 1, the top of the body of rod 4 is connected with blade 2, and blade 2 constructs for hook form, saw head form, collude form or forked form. A triangular support is arranged at the bottom of the lifting motor 2 and used for supporting the shell 1, the blade 2, the lifting motor 3 and the rod body 4.

The blade 2 can be sickle-shaped, the structure of which is shown in fig. 2, and can be a sickle or a firewood knife, and the blade 2 can also be saw-head-shaped, as shown in fig. 3.

When the blade 2 is used as an obstacle removing tool, the blade can be forked, and as shown in fig. 4, the blade is used for pushing the branch close to the electric wire away from the direction of the electric wire so as to prevent the electric wire from being touched by mistake in the cleaning process.

The blades 2 can be hook-shaped, as shown in fig. 5, and have the function of drawing the more distant branches closer to one point, so that the cleaning is convenient.

The rod body 4 is connected with the blade 2 through the fixed shaft, the fixed shaft is detachably connected with the rod body 4 and the blade 2, if the connecting portion of the fixed shaft, the blade 2 and the rod body 4 is provided with a protrusion, the blade 2 and the rod body 4 are provided with a recess matched with the protrusion, and the fixed shaft, the blade 2 and the rod body 4 are in threaded connection.

When the multifunctional knife is used, the triangular support is opened and fixed on the ground, the lifting motor 3 is started until the blade 2 reaches the required height, the triangular support is folded, and then corresponding operation is carried out.

Example 2

The embodiment is based on embodiment 1, and provides a portable combined tool for removing tree obstacles, the structure of which is shown in fig. 6, the embodiment is based on embodiment 1, and the structure of which is shown in fig. 8, and the combined tool for removing tree obstacles comprises a housing 1, a first lifting motor 5 is arranged at the bottom of the housing 1 (specifically, a telescopic rod of the first lifting motor 5 is connected with the housing 1), so that the housing 1 can reciprocate in the vertical direction, that is, the height of the housing 1 can be adjusted, and a triangular bracket (not shown in the figure) is installed at the bottom of the first lifting motor 5. The housing 1 is internally provided with a movable mechanism.
