[0029] On one side of a common chainsaw is the sprocket portion of the chainsaw, and on the other side is the motor portion 5 of the chainsaw. To prevent the user's hand holding the side grip 4 from approaching the saw teeth 1 of the chainsaw accidentally when the chainsaw is working, the side grip 4 is installed on one side of the motor portion 5.

[0030] The handle mounting base 2 protrudes and is provided on the front side above the main body portion 7. The handle mounting base 2 is connected to the main grip 11, and the main grip 11 is arranged in the front-back direction.

[0031] The handle mounting base 2 and the main body portion 7 can be fixedly connected by welding, screw connection or integrally formed connection methods. Preferably, the handle mounting base 2 and the main body portion 7 are connected and fixed by an integrally formed method.

[0032] The handle mounting base 2 is provided with a first mounting portion 3 for installing one end of the side grip 4. The first mounting portion 3 and the handle mounting base 2 can be fixedly connected by welding or integrally formed methods. Preferably, the handle mounting base 2 and the first mounting portion 3 are connected and fixed by an integrally formed method.

[0033] As Figure 2 shown, the first mounting portion 3 is located on the side wall at the top end of the handle connecting seat. The first mounting portion 3 can be on the same side of the main body portion 7 as the motor portion 5, or can be installed on the other side of the main body portion 7. Preferably, the first mounting portion 3 is installed on the same side as the motor portion 5.

[0034] The motor part 5 is arranged on the side of the main body part 7 away from the chain saw teeth 1. The main body of the motor part 5 protrudes outward, providing sufficient installation space for the motor inside the main body part 7. One end of the protruding part of the motor part 5 close to the side grip 4 is designed in a triangular shape, which can reduce the volume of part of the protruding part of the motor part 5 and better prevent the user's hand from touching the motor part 5 when grasping the side grip 4.
