Description

TECHNICAL FIELD

[0001] The utility model relates to electric saw technical field especially, relates to a kind of electric impact high branch saw. BACKGROUND

[0002] In the technical field of distribution network live maintenance, due to the trees along the power line grow too fast, which can directly contact the power cable, and may cause line short circuit, electric shock accident. Therefore, it is necessary to develop an insulated multifunctional tree cutting tool for easy carrying, to repair the trees near the power cable that affect power transmission safety on a regular basis.

[0003] To protect the safety of power lines, high branch saws are used to trim trees that may contact power lines, to prevent short circuits or electric shock accidents caused by tree branches contacting the conductor. This is a key issue for the safe operation of urban lines. If the trees are not properly trimmed, their growth may contact the line, causing inter-phase short circuit, causing power outage, and even injuring passing pedestrians.

[0004] Traditional tree trimming tools, such as handheld saws or chain saws, have high labor intensity and low efficiency. Electric high branch saws can improve trimming efficiency and reduce labor intensity for workers. However, when the tree is too hard and the cut is too deep, the saw blade will be stuck in the tree. This limits the use of the device in areas with hard wood. UTILITY MODEL CONTENT

[0008] Preferably, the impact transmission mechanism includes a housing connected with the impact structure fixing seat, a sliding sleeve is arranged inside the housing, the lower end of the sliding sleeve is connected with the shaft body d through an elastic member, the sliding sleeve, the elastic member and the shaft body d rotate synchronously, a shaft body c is rotatably connected to the upper end of the housing, the shaft body c is fixed on the saw seat through a bearing seat, the upper end of the shaft body c is connected with the bevel gear mechanism, and the lower end thereof extends into the housing and is connected with an oval head, a center-symmetrically distributed inclined surface step is arranged on the upper end of the sliding sleeve.

[0009] Preferably, the upper end of the shaft body d is an elliptical structure, and the lower end of the sliding sleeve is provided with an elliptical hole corresponding to the shaft body d.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the driving mechanism in the present invention drives the cutting saw blade to rotate through the impact transmission mechanism to perform work. When the saw is stuck, the load on the shaft C increases, and the inclined step continues to rotate to overcome the rebound force of the elastic part. When the elliptical head passes over the inclined step, under the action of the rebound force of the elastic part, the elliptical head collides with the sliding sleeve, causing the entire saw body to vibrate, thereby ensuring that the cutting saw blade is free from restraint.
