[0002] During the growth process of existing standing trees, it is necessary to timely observe the growth conditions of the standing trees, and the staff should timely prune or tip the relevant standing trees to facilitate the healthy growth of the standing trees. Or when researching relevant standing trees in a region, when scientific research personnel are researching a certain standing tree, sometimes it is necessary to cut off its branches for collection to facilitate the later collation of relevant data of the standing trees, etc. Or when removing the danger of the dead branches (trunks) of the standing trees, or when collecting seeds or fruits of some plants, it is necessary to cut off the corresponding branches.

[0003] For short standing trees, pruning or tipping can be directly carried out manually with scissors; or when the terrain is relatively flat and there is no dense understory vegetation around, and it is convenient for personnel to climb, relevant personnel can also prune, cut or tip the standing trees by means of ladders or climbing trees. However, for tall standing trees in complex areas or the branches of relevant standing trees with high strength or being too thick, using the above-mentioned methods will cause certain dangers and high working intensity.

Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] The following embodiments are used for pruning or topping the standing trees during their growth process to facilitate their healthier growth; or when studying a certain type of standing trees in a region, for facilitating the subsequent collation of relevant data of the standing trees, etc., cutting their branches for collection; or when carrying out risk removal treatment on the dead branches (trunks) of the standing trees, or when carrying out truncation treatment on the branches during the collection of seeds, fruits, etc. of some plants. To better reflect the practicability of this solution, this solution is integrated with the wire saw guiding device designed in the present invention to achieve pruning or trunk cutting of the corresponding forest trees.

[0018] Please refer to Figures 1 - 3 , this embodiment provides a technical solution: a simple high-altitude pruning and trunk cutting device, including a telescopic rod 1 and a guiding rope 3 with a wire saw 4 arranged in the middle;

[0019] A wire saw guiding device 2 is fixedly arranged on the rod head of the telescopic rod 1;

[0020] The wire saw guiding device 2 includes a guiding main body 6 and a rotatable steering rod 5 that can rotate bidirectionally. The guiding main body 6 is of a U-shaped structure as a whole. The rotatable steering rod 5 is placed at the U-shaped opening of the guiding main body 6 and can rotate bidirectionally. The tail of the rotatable steering rod 5 is connected to the top end of the guiding rope 3. The guiding main body 6 is of a double-row structure. A steering shaft 1.5 is arranged between the double-row rods at the left end of the U-shaped opening, and hook catches 1.4 are arranged on both double-row rods at the right end of the U-shaped opening. An arc-shaped card slot 5.1 is arranged on the lower surface of the left end of the rotatable steering rod 5, and a clamping rod 5.2 is arranged at the right end of the rotatable steering rod 5. Among them, the arc-shaped card slot 5.1 cooperates with the steering shaft 1.1 to enable the right end of the rotatable steering rod 5 to rotate clockwise downward, and the clamping rod 5.2 cooperates with the hook catch 1.4 to enable the left end of the rotatable steering rod 5 to rotate clockwise upward. The space formed by the gap between the double-row structures of the left support rod 1.2 and the right support rod 1.3 forms a space for placing, removing, or steering the rotatable steering rod 5.

[0021] In use, first adjust the length of the telescopic rod 1 (generally set with a three-section telescopic structure, and the adjacent telescopic sections can be connected by threads to maximize space savings during later placement). The length is generally about 3 - 10 m for high-altitude tree branches. Then, the operator lifts the telescopic rod 1 and brings the rotatable steering rod 5, which can rotate in two directions, close to the branches of the corresponding standing tree, and makes the rotatable steering rod 5 on the side of the clamping rod 5.2 press tightly against the branches. Then, pre-tighten the guiding rope 3 and simultaneously slowly and forcefully push against the branches, so that the rotatable steering rod 5 can rotate inwards around the steering shaft 1.5. At this time, the corresponding branches will slowly be caught in the U-shaped structure of the wire saw guiding device 2. Then, move the telescopic rod 1 so that the branches are in contact with the rotatable steering rod 5 on the side of the arc-shaped card slot 5.1. Then, pre-tighten the guiding rope 3 and simultaneously slowly and forcefully pull back the telescopic rod. Then, the corresponding branches push the rotatable steering rod 5 outwards, so that the rotatable steering rod 5 can rotate outwards around the clamping rod 5.2. Then, the branches leave the U-shaped structure and at the same time the guiding rope 3 completes the winding around the corresponding branches. Retrieve the telescopic rod 1 and bring the rotatable steering rod 5 back to the operator's hand, that is, the operator can control both ends of the guiding rope 3. After the guiding rope 3 completes the winding around the corresponding tree top or branches 8, the two ends of the guiding rope 3 are respectively fixed on the connecting posts 7.5 on the corresponding turntables 7.3. The actions of the two turntables 7.3 for stretching / or scaling the guiding rope 3 are just opposite. At the same time, under the action of the pre-tightening device 7.6 and the pre-tightening spring 7.8, the wire saw 4 can ensure a certain pre-pressure to perform reciprocating cutting on the tree top or branches. And under the action of the pre-tightening device 7.6 and the pre-tightening spring 7.8, it is allowed that the guiding ropes 3 on both sides of the tree top or branches have a certain tensile strength within different length ranges (so as to ensure the pre-pressure of the wire saw 4 on the tree top or branches).

[0022] The standard parts used in this embodiment can all be purchased from the market. The special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
