Long-reach pruning shears

Abstract

The invention relates to long-reach pruning shears which comprise a telescopic rod, a cutter frame, a rotary cutter and a stay. The cutter frame is arranged on the top of the telescopic rod, the rotary cutter is rotationally connected onto the cutter frame, and the stay is connected with the rotary cutter by a rotation structure and is used for pulling the rotary cutter to rotate. The long-reach pruning shears are characterized in that grooves which are used for accommodating the stay are formed in the outer wall of the telescopic rod, and a stay fixing structure is arranged on the outside of the telescopic rod, so that the stay can cling into the grooves in the outer wall of the telescopic rod. Compared with the prior art, the long-reach pruning shears have the advantages that the grooves which are used for accommodating the stay are formed in the outer wall of the telescopic rod, and the stay clings into the grooves in the outer wall of the telescopic rod and accordingly can be prevented from interfering with work of operators in operation procedures.

Description

technical field [0001] The invention relates to a high branch shear. Background technique [0002] Tree corolla pruning is an important task in garden maintenance. Pruning can promote the growth of branches, reduce the branches and leaves of closed canopy, improve ventilation and light transmission, and reduce the occurrence of diseases and insect pests. Pruning is generally done by garden technicians with pruning shears. For general hedges, low shrubs or small trees, common garden scissors mainly composed of two blades and a shear shaft can be used to complete. If you want to trim the high branches of trees, you usually need to use a ladder to cut off the branches that need to be trimmed. It is very inconvenient to trim, the work efficiency is low, and you need to climb the ladder, which is very unsafe. In addition, a knife is fixed on the long pole, and the branches are cut off by the knife, which is very laborious to use. If you cut thick branches, you must use a saw to...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following defects in the above-mentioned structure: one, the stay cord is exposed outside the telescopic rod, and when in use, the exposed stay cord can swing and shake, thereby disturbing the work of the operator; two, the length of the stay cord is fixed, in order to It will not hurt your hands when pulling the drawstring. Most people will pull the pull ring at the end of the pull rope when operating, and then different users have different heights and body shapes. It is best when the pull ring is higher or lower than the user The comfortable position of pulling gestures will bring unpleasant experience to the user, so the fixed-length drawstring is not suitable for users of all body types and sizes; 3. The rotating structure of the drawstring to drive the rotating knife—hinge chain , The helical spring is also directly exposed, and the structure is easily disturbed or damaged by the falling branches, which will cause inconvenience in use
