The electric chain saw provides a chain saw with high heat dissipation effect, including: a frame, a motor fixedly installed on the frame, a sprocket fixedly installed on the output shaft of the motor, a guide plate with one end installed on the frame, and a fixed installation A guide plate cover is fixedly installed on the frame at the other end of the guide plate, the guide plate cover is arranged outside the guide plate, and the edge of the guide plate is evenly opened with multiple heat dissipation holes; an automatic tensioner for adjusting the tension of the saw chain is arranged between the guide plate and the guide plate. The automatic tensioner includes a sliding block fixedly installed on the guide plate, a sliding block fixedly connected to the guide plate at one end, and a spring installed on the sliding block. The slider is provided with a sliding hole installed on the slider, one end of the spring abuts against the slider, and the other end abuts against the guide plate. The invention adopts an automatic tensioning device to properly tension the saw chain and reduce heat generation. The setting of multiple heat dissipation holes makes it easy to disperse the heat generated by the rapid movement of the saw chain. Then let's learn how to improve the heat dissipation effect of the electric chain saw!

The electric chain saw is a traditional electric tool, which is not only suitable for forest cutting and timber selection, but also for construction, shipbuilding, bridges, railways, mines and other departments. The chain saw drives the chain saw teeth through the driving mechanism. The conventional chain saw is equipped with an oil injection device at a portion near the chain saw, and the chain saw is operated to provide lubricating oil to the chain saw every 10 minutes. The installation of the fuel injection device must be equipped with a fuel supply system, which has a high failure rate, which brings inconvenience to users and high processing costs.

The electric chain saw is a chain saw that reduces cost, easily reduces temperature, and has a high heat dissipation effect.

In order to achieve the above object, the present invention provides a frame, a motor fixedly installed on the frame, a sprocket fixedly installed on the output shaft of the motor, a guide plate with one end installed on the frame, and a second sprocket fixedly installed on the other end. In a chain saw with a sprocket and teeth meshing with the second sprocket, a guide plate is fixedly installed on the frame, the guide plate cover is arranged outside the guide plate,

the edge of the guide plate is evenly provided with a plurality of heat dissipation holes;

An automatic tensioner for adjusting the tension of the saw chain is arranged between the guide plate and the guide plate. The automatic tensioner includes a sliding block fixedly installed on the guide plate, a sliding block fixedly connected to the guide plate at one end, and a spring installed on the sliding block. The slider is provided with a sliding hole installed on the slider, one end of the spring abuts against the slider, and the other end abuts against the guide plate.

Moreover, a strip-shaped adjusting groove is provided on the guide plate, a guide rod is fixedly installed on the frame, and the guide rod penetrates through the strip-shaped adjusting groove.

In addition, there are two guide rods, and the two guide rods pass through the rod-shaped adjusting groove at the same time.

The guide rod is screwed with a nut passing through the rod-shaped adjusting groove and the mounting hole of the guide plate cover in turn, and the nut abuts against the guide plate cover.

And the guide plate cover is provided with a sliding groove engaged with the slider.

And the slider will be exposed outside the chute.

The guide plate further includes two outer plates disposed in parallel and an inner plate disposed between the two outer plates, and the second sprocket is disposed between the two outer plates. A heat dissipation hole is also provided at an edge of the at least one outer plate.

And an armrest is fixedly installed on the frame.

In addition, the armrest is also provided with a control button for starting or stopping the motor.

Compared with the prior art, the electric chain saw omits the fuel injection device and the fuel supply system, so that the use of the electric chain saw is more environmentally friendly. At the same time, it reduces the production cost, reduces the failure rate of later use, and also reduces the user's use cost. In addition, the automatic tensioning device is adopted to properly tension the chainsaw, so as to avoid excessive tensioning of the chainsaw and reduce heat generation. A plurality of heat dissipation holes are opened on the guide plate to facilitate the dispersion of heat generated by the rapid movement of the chainsaw.
