Description

Technical Field

[0001] This utility model relates to the field of chainsaw technology, specifically to an adjustable-angle lithium chainsaw. Background Technology

[0002] In many fields such as woodworking, garden trimming, home renovation, and DIY projects, the chainsaw serves as a core cutting tool, and its performance and ease of use directly affect work efficiency and cutting quality. Traditional lithium-ion chainsaws, limited by their structural design, often have fixed angles for the guide plate and chain. When faced with complex tasks such as beveling or multi-angle cutting, users often need to frequently adjust the workpiece's position, which is not only cumbersome and time-consuming but also makes it difficult to guarantee the accuracy of the cutting angle. This limitation is particularly pronounced when dealing with irregularly shaped workpieces or cutting tasks at specific angles, and traditional equipment can no longer meet the demands of modern work scenarios for efficient and flexible cutting tools.

[0003] For example, Chinese patent CN212278974U discloses an adjustable-angle lithium electric saw, including a shell, a chain and a guide plate for mounting the chain on the shell, a drive motor for driving the chain in the shell, and a mounting seat for mounting the chain and guide plate on the shell. The mounting seat is rotatably mounted on the shell and fixed to the shell by fasteners. The purpose of this utility model is to provide an adjustable-angle lithium electric saw that is easy to use and easy to install.

[0004] However, the aforementioned adjustable-angle lithium electric saw uses fasteners to fix the mounting base and the outer casing relatively. Each time the angle is adjusted, the fasteners need to be loosened with a tool and then tightened again after adjustment. The operation is cumbersome, especially in scenarios with high-frequency angle adjustments, which not only prolongs the angle switching time but also reduces work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable-angle lithium electric saw to solve the problem mentioned in the background art that lithium electric saws require tools to adjust the angle, which is cumbersome and inefficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable-angle lithium-ion electric saw includes: a lithium-ion electric saw body; a sprocket is fixedly installed on one side of the chain drive end of the lithium-ion electric saw body; a chain meshing with the outer surface of the sprocket is fitted onto the outer surface of a guide plate; the guide plate is rotatably mounted on a docking plate and the chain drive end by means of rings fixedly installed at both ends; the docking plate is fixedly installed on one end of the chain drive end of the lithium-ion electric saw body and covers the other side of the sprocket; and an angle adjustment mechanism is rotatably installed inside the docking plate.

[0007] Preferably, the angle adjustment mechanism includes a knob, which is rotatably installed inside the docking plate. The knob is fixedly connected to the inner ring wall of the ring through a semi-circular opening, so that the knob can rotate to drive the guide plate and the chain fitted on the outer surface to adjust the angle between the lithium electric saw body and the docking plate. The semi-circular opening is opened at one end inside the ring.

[0008] Preferably, the outer surface of the knob is provided with an embedded anti-slip groove, and multiple sets of protruding teeth are arranged at equal intervals in the anti-slip groove. The spacing between the protruding teeth is such that the protruding teeth on the lower surface of the arc pressure plate can be inserted into them. The arc pressure plate is slidably installed in the upper part of the docking plate.

[0009] Preferably, a connecting column is fixedly installed on the upper surface of the arc pressure plate. The connecting column is slidably inserted into the guide cylinder and slides out through it. The guide cylinder is connected to the upper end of the outer surface of the docking plate, and a lifting ball is fixedly installed on the upper surface of the connecting column that slides out through the guide cylinder.

[0010] Preferably, a rectangular spring is fitted on the outer surface of the connecting column inside the guide cylinder. The upper end of the rectangular spring is fixedly connected to the inner top of the guide cylinder, and the other end of the rectangular spring is fixedly connected to the upper surface of the arc pressure plate.

[0011] Preferably, the rectangular spring can apply a downward spring force to the arc pressure plate, so that the arc pressure plate can be firmly pressed into the anti-slip groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the coordinated transmission design of the lithium-ion electric saw body, sprocket, and guide plate, electrical energy can be efficiently converted into cutting power, ensuring efficient cutting operations. In terms of angle adjustment, the operator only needs to pull the lifting ball of the connecting column upwards to release the lock between the arc pressure plate and the knob. Manually turning the knob will drive the guide plate to adjust the angle. After releasing the lifting ball, the rectangular spring will automatically push the arc pressure plate to engage and lock with the anti-slip groove. The entire adjustment process does not require any additional tools, making the operation simple and quick. The locking structure can effectively prevent angle deviation caused by vibration during cutting, ensuring cutting accuracy. At the same time, the flexible angle adjustment function can adapt to the diverse cutting needs in different scenarios such as woodworking and garden pruning, significantly improving the flexibility and practicality of the lithium-ion electric saw.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-3As shown, this embodiment provides an adjustable-angle lithium electric saw, including: a lithium electric saw body 1, a sprocket 101 fixedly installed on one side of the chain drive end of the lithium electric saw body 1, a chain meshing and driving on the outer surface of the sprocket 101 is fitted on the outer surface of the guide plate 102, the guide plate 102 is damped and rotated in the docking plate 103 and the chain drive end by rings 106 fixedly installed at both ends, the docking plate 103 is fixedly installed on one end of the chain drive end of the lithium electric saw body 1 and covers the other side of the sprocket 101, and an angle adjustment mechanism 2 is rotatably installed in the docking plate 103. Through the design of the lithium-ion electric saw body 1, sprocket 101, guide plate 102, docking plate 103, ring 106, and angle adjustment mechanism 2, when started, the power component inside the lithium-ion electric saw body 1 converts electrical energy into mechanical energy and transmits it to the chain drive end, driving the sprocket 101, which is fixedly installed on one side of the chain drive end, to rotate. Since the outer surface of the sprocket 101 meshes with the chain fitted on the outer surface of the guide plate 102, the rotation of the sprocket 101 synchronously drives the chain to circulate along the outer surface of the guide plate 102. At this time, the cutting teeth on the chain can contact the workpiece to be cut, realizing the cutting operation. When it is necessary to adjust the cutting angle according to the operation requirements, the operator can operate the angle adjustment mechanism 2, which is rotatably installed in the docking plate 103, to drive the guide plate 102 to move. Since the guide plate 102 is fixedly installed at both ends... The ring 106 is rotatably installed inside the chain drive end of the docking plate 103 and the lithium electric saw body 1. Under the action of the angle adjustment mechanism 2, the guide plate 102 can rotate smoothly between the docking plate 103 and the chain drive end with the ring 106 as the rotation fulcrum, thereby changing the cutting angle of the chain on the outer surface of the guide plate 102. After the angle is adjusted to the required position, the angle adjustment mechanism 2 is stopped. The angle adjustment mechanism 2 will lock the position of the guide plate 102 to ensure that the guide plate 102 maintains a stable angle in subsequent cutting operations. At the same time, the docking plate 103 is always covered on the other side of the sprocket 101, which not only provides stable support for the rotation of the guide plate 102, but also protects the transmission parts of the sprocket 101 and the chain, preventing impurities from entering during the cutting process and affecting the transmission stability, thereby achieving precise and stable cutting operations at different angles.

[0017] like Figures 2-3As shown, the angle adjustment mechanism 2 includes a knob 203, which is rotatably mounted inside the docking plate 103. The knob 203 is fixedly connected to the inner ring wall of the ring 106 through a semi-circular opening 104, so that the knob 203 can rotate to drive the guide plate 102 and the chain mounted on the outer surface to adjust the angle between the lithium electric saw body 1 and the docking plate 103. The semi-circular opening 104 is opened at one end inside the ring 106. The outer surface of the knob 203 has an embedded anti-slip groove 204. Multiple sets of protruding teeth are evenly arranged in the anti-slip groove 204, and the spacing between the protruding teeth is sufficient for the protruding teeth on the lower surface of the arc pressure plate 201 to be inserted. The arc pressure plate 201 is embedded and slidably mounted on the upper end of the docking plate 103. A connecting post 202 is fixedly installed on the upper surface of plate 201. The connecting post 202 is slidably inserted into the guide cylinder 105 and slides out through it. The guide cylinder 105 is connected to the upper end of the outer surface of the docking plate 103. A lifting ball is fixedly installed on the upper surface of the connecting post 202 that slides out through the guide cylinder 105. A rectangular spring 205 is fitted on the outer surface of the connecting post 202 inside the guide cylinder 105. The upper end of the rectangular spring 205 is fixedly connected to the inner top of the guide cylinder 105. The other end of the rectangular spring 205 is fixedly connected to the upper surface of the arc pressure plate 201. The rectangular spring 205 can apply a downward spring force to the arc pressure plate 201, so that the arc pressure plate 201 can be firmly pressed into the anti-slip groove 204.

[0018] Through the design of the arc pressure plate 201, connecting column 202, knob 203, anti-slip groove 204, and rectangular spring 205, when the cutting angle of the lithium electric saw needs to be adjusted, the operator can pull the lifting ball on the upper surface of the connecting column 202 upwards, causing the connecting column 202 to slide upwards along the guide cylinder 105. At this time, the connecting column 202 will simultaneously pull the arc pressure plate 201 upwards, causing the protrusions on the lower surface of the arc pressure plate 201 to disengage from the protrusion spacing in the anti-slip groove 204 on the outer surface of the knob 203. Simultaneously, the rectangular spring 205 inside the guide cylinder 105 will be compressed and store elastic potential energy. Then, the operator can directly turn the knob 203. Since the knob 203 is fixedly connected to the inner ring wall of the ring 106 through the semi-ring opening 104, and the ring 106 is fixedly installed at both ends of the guide plate 102, the knob... The rotation of 203 will drive the guide plate 102 and the chain mounted on the outer surface to rotate around the ring 106 as the fulcrum to adjust the angle until the desired cutting angle is reached. At this time, the lifting ball is released, and the compressed rectangular spring 205 will release its elastic potential energy, applying a downward spring force to the arc pressure plate 201, pushing the arc pressure plate 201 to slide down along the upper end of the mating plate 103, so that the protrusions on the lower surface of the arc pressure plate 201 are re-inserted into the corresponding protrusion spacing in the anti-slip groove 204. The engagement between the protrusions achieves a stable lock of the knob 203, thereby fixing the angle of the guide plate 102 and the chain, ensuring that the angle will not shift due to vibration or other factors during the cutting operation. The entire angle adjustment process does not require additional tools, is convenient to operate and locks securely, effectively improving the flexibility and cutting accuracy of the lithium electric saw.

[0019] Working principle: Upon startup, the power component inside the lithium-ion electric saw body 1 converts electrical energy into mechanical energy and transmits it to the chain drive end, causing the sprocket 101, which is fixedly installed on one side of the chain drive end, to rotate. Since the outer surface of the sprocket 101 meshes with the chain mounted on the outer surface of the guide plate 102, the rotation of the sprocket 101 synchronously drives the chain to circulate along the outer surface of the guide plate 102. At this time, the cutting teeth on the chain can contact the workpiece to be cut, achieving the cutting operation. When it is necessary to adjust the cutting angle according to the operation requirements, the operator can pull up the lifting ball on the upper surface of the connecting column 202, causing the connecting column 202 to slide upward along the guide cylinder 105. At this time, the connecting column 202 will synchronously pull the arc pressure plate 201 upward, causing the protrusions on the lower surface of the arc pressure plate 201 to disengage from the protrusion spacing in the anti-slip groove 204 on the outer surface of the knob 203. Simultaneously, the rectangular spring 205 inside the guide cylinder 105 will... The spring 203 is compressed and stores elastic potential energy. The operator can then directly turn the knob 203. Since the knob 203 is fixedly connected to the inner ring wall of the ring 106 through the semi-ring 104, and the ring 106 is fixedly installed at both ends of the guide plate 102, the rotation of the knob 203 will drive the guide plate 102 and the chain mounted on the outer surface to rotate around the ring 106 as the fulcrum until the required cutting angle is reached. At this time, the lifting ball is released, and the compressed rectangular spring 205 will release elastic potential energy, applying a downward elastic force to the arc pressure plate 201, pushing the arc pressure plate 201 to slide down along the upper end of the mating plate 103, so that the protrusions on the lower surface of the arc pressure plate 201 are re-inserted into the corresponding protrusion spacing in the anti-slip groove 204. The engagement between the protrusions achieves the stable locking of the knob 203, thereby fixing the angle of the guide plate 102 and the chain, ensuring that the angle will not shift due to vibration or other factors during the cutting operation.

[0020] In summary: The entire adjustment process requires no additional tools, making operation simple and quick. The locking structure effectively prevents angle deviation caused by vibration during cutting, ensuring cutting accuracy. At the same time, the flexible angle adjustment function can adapt to diverse cutting needs in different scenarios such as woodworking and garden pruning, significantly improving the flexibility and practicality of the lithium-ion electric saw.
