Description

Technical Field

[0001] The utility model belongs to the technical field of garden maintenance, and in particular relates to a garden maintenance long-pole branch sawing device which is easy to operate. Background Art

[0002] In the process of garden maintenance, branches high up in the trees will be pruned, and a high branch saw will be used to trim the branches, eliminating the need for operators to climb trees or use ladders, and avoiding the risk of operators falling from heights. Chinese patent application number 201921 137697.1 discloses a high branch saw for garden maintenance. It can be seen that the content describes a long pole sawing device for garden maintenance that is easy to operate.

[0003] When using the existing garden maintenance long pole saw device, the user holds the handle on the high branch saw and then raises the saw blade to saw and prune the high branches. However, since the long pole on the high branch saw is long, when sawing thicker branches, the saw blade is easy to jump when moving up and down, which makes it inconvenient for the saw blade to saw along the saw cut on the branch all the time. Moreover, after sawing to a certain depth, the saw will jump and the saw will have to be reopened from the saw cut of the branch. Therefore, we propose a garden maintenance long pole saw device that is easy to operate. Utility Model Content

[0004] The utility model aims to provide a garden maintenance long pole sawing device that is easy to operate, so as to solve the problem that when the existing garden maintenance long pole sawing device is used, the long pole body on the high branch saw is long, and the saw blade is easy to jump when moving up and down.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a garden maintenance long pole sawing device that is easy to operate, comprising a saw blade and a long pole body, a connecting head is arranged between the saw blade and the long pole body, a limiting assembly is arranged on the saw blade, the limiting assembly comprises a limiting piece and a pulling piece, the limiting piece comprises an arc-shaped plate and a spring, a lower plate is fixedly arranged at the bottom of the connecting head, one end of the arc-shaped plate is rotatably connected to the lower plate through a rotating shaft, a connecting plate is fixedly arranged at the bottom of the arc-shaped plate, a lower ring is fixedly arranged at the bottom of the lower plate, a plurality of groups of mounting rings are fixedly arranged at the bottom of the long pole body, a connecting rope is fixedly arranged on the side of the connecting plate, and the end of the connecting rope passes through the lower ring and the interior of the mounting ring.

[0006] Preferably, an upper block is fixedly provided on the front side of one end of the saw blade, a lower block is fixedly provided on the top of one end of the arc-shaped plate, and the spring is located between the upper block and the lower block.

[0007] Preferably, the top of the spring is fixedly connected to the upper block, and the bottom of the spring is fixedly connected to the lower block.

[0008] Preferably, the mounting rings are evenly distributed along the length direction of the long rod.

[0009] Preferably, the inner wall of the arc-shaped plate is provided with a plurality of rolling grooves, and rolling balls are arranged inside the rolling grooves.

[0010] Preferably, a plurality of groups of saw teeth are fixedly provided on the inner wall of the saw blade, and a handle is fixedly provided on the bottom end of the long rod body.

[0011] Preferably, the connecting head is fixed to the top end of the long rod, and the saw blade is fixed to the connecting head.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The utility model is designed with a limit assembly. When in use, the arc plate is opened by pulling the connecting rope. Then, after the saw blade is placed on a thicker branch, the thicker branch is placed between the saw blade and the arc plate. Then, the connecting rope is released. At this time, the arc plate is closed under the action of the spring. At this time, the arc plate clamps the thicker branch and limits it, so that the saw teeth on the inner wall of the saw blade can always be in close contact with the thicker branch. Then, the saw blade is limited in position during the sawing process of the thicker branch, which reduces the vibration or saw jumping of the saw blade and facilitates operation and use.

The spring 205 is located between the upper block 204 and the lower block 207. The top of the spring 205 is fixedly connected to the upper block 204, and the bottom of the spring 205 is fixedly connected to the lower block 207. The mounting ring 203 is evenly distributed along the length direction of the long rod body 102. Through the designed limit assembly, the arc plate 200 is opened by pulling the connecting rope 202 when in use, and then After the saw blade 100 is placed on a thicker branch, the thicker branch is placed between the saw blade 100 and the curved plate 200, and then the connecting rope 202 is released. At this time, the curved plate 200 is closed under the action of the spring 205. At this time, the curved plate 200 clamps the thicker branch and limits it, so that the teeth on the inner wall of the saw blade 100 can always be in close contact with the thicker branch. Then, the saw blade 100 is limited during the process of sawing the thicker branch, which reduces the jumping or saw jumping of the saw blade 100, making it easier to operate and use.

[0024] The working principle and use process of this utility model:

[0025] When the utility model is in use, the handle 103 is held to stand up the high branch saw, and then the bottom end of the connecting rope 202 is held and pulled outward, at which time the spring 205 is affected and begins to stretch, and the curved plate 200 is rotated counterclockwise around the rotating shaft to open, and then the saw blade 100 is placed on the thicker branch to be sawed, so that the thicker branch is located between the saw blade 100 and the curved plate 200, and then the connecting rope 202 is slowly loosened, and then the spring 205 is reset, so that the curved plate 200 can be pulled in the clockwise direction, and then the curved plate The rolling ball 300 on the inner wall of 200 contacts the branch, and then the high branch saw is moved up and down. At this time, the saw blade 100 can start to saw the branch. During this process, the curved plate 200 rotates under the action of the spring 205, so that the saw teeth on the inner wall of the saw blade 100 are in close contact with the branch. At this time, the rolling ball 300 that contacts the branch rolls. When the branch is sawed, the bottom end of the connecting rope 202 is held again and pulled outward, driving the curved plate 200 to rotate counterclockwise. At this time, the curved plate 200 can be opened, and then the high branch saw can be taken away.
