Description

Technical Field

[0001] This utility model belongs to the technical field of chainsaw equipment, specifically relating to a chainsaw with a shock-absorbing handle. Background Technology

[0002] A chainsaw, also known as a tack saw, is a hand-held saw powered by a gasoline engine, primarily used for logging and timber processing. Its working principle relies on the lateral movement of L-shaped blades along a saw chain to perform the cutting action. Chainsaws are generally classified into motorized chainsaws and non-motorized chainsaws. 。

[0003] Because chainsaws are powered by gasoline engines, they vibrate significantly during operation, especially around the handle where the user holds it. The handle is directly connected to the cylinder block and crankcase, and the handle vibrates considerably. If the user holds it for a long time, it can easily cause numbness in the user's hands, increasing the user's workload and causing fatigue. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a chainsaw with a shock-absorbing handle. By setting a shock-absorbing component, which is connected between the machine body and the handle, the vibration generated by the machine body is eliminated or reduced by the shock-absorbing component before being transmitted to the handle, thereby reducing the vibration of the handle, improving the user's comfort in holding the chainsaw, reducing the user's labor intensity, and extending the time the user can hold the chainsaw to work.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A chainsaw with a shock-absorbing handle includes a body and a handle, the handle being connected to the body. A shock-absorbing assembly connects the body and the handle, the shock-absorbing assembly including a first buffer and a second buffer. The body includes a crankcase and a cylinder block, the cylinder block being connected to the crankcase. The first buffer is connected between the bottom ends of the handle and the crankcase, and the second buffer is connected between one side of the handle and the cylinder block. This invention, by incorporating a shock-absorbing assembly connected between the body and the handle, eliminates or reduces vibrations generated by the body before transmitting them to the handle, thereby reducing handle vibration, improving user comfort when holding the chainsaw, reducing user labor intensity, and extending the time the user can hold the chainsaw while working.

[0007] Furthermore, the handle includes a mounting base plate, an arc-shaped grip portion, and a side connecting portion. One end of the arc-shaped grip portion is fixedly connected to the top of the side connecting portion, the other end of the arc-shaped grip portion is fixedly connected to one end of the mounting base plate, and the bottom end of the side connecting portion is fixedly connected to the other end of the mounting base plate. The mounting base plate is used to fix the arc-shaped grip portion to the body, the arc-shaped grip portion is convenient for the user to hold, and the side connecting portion is used to connect the arc-shaped grip portion and the mounting base plate.

[0008] Furthermore, the mounting base, the curved grip, and the side connection parts are all integrally molded. This integral molding structure significantly improves the structural strength of the handle.

[0009] Furthermore, the bottom of the crankcase is provided with a mounting groove, and the mounting base plate is fixed in the mounting groove, so that the bottom surface of the mounting base plate and the bottom surface of the crankcase are kept on the same plane.

The other end of the buffer spring is fixed to the fixing part via the threaded groove. The U-shaped hook at one end of the buffer spring facilitates fixing it to the crankcase using the limiting bolt. The other end of the buffer spring is fixed to the fixing part via the threaded groove, thus fixing the buffer spring between the crankcase and the mounting base plate. When the chainsaw is working, vibrations on the crankcase are eliminated or weakened by the buffer spring before being transmitted to the handle, reducing the vibration experienced by the handle.

[0011] Furthermore, the second buffer component includes a second limiting bolt and a second buffer spring. One end of the second buffer spring has a second U-shaped hook. The second limiting bolt passes through the second U-shaped hook and is screwed into the cylinder body, thus fixing one end of the second buffer spring to the cylinder body. The side connection part has a second fixing part with a second threaded groove. The second threaded groove matches the second buffer spring, and the other end of the second buffer spring is limited on the second fixing part through the second threaded groove. The second U-shaped hook at one end of the second buffer spring facilitates the fixed connection of one end of the second buffer spring to the cylinder body by the second limiting bolt. The other end of the second buffer spring is limited on the second fixing part through the second threaded groove, thereby fixing the second buffer spring between the cylinder body and the handle. When the chainsaw is working, the vibration on the cylinder body is eliminated or weakened by the second buffer spring and then transmitted to the handle, reducing the vibration on the handle and improving the user's grip comfort.

[0012] Furthermore, the machine body is also equipped with a protective baffle, which is located on the front side of the curved handle.
