[0026] A mounting assembly is provided on the right side of the battery box 2, and the mounting assembly includes a cover plate 14 movably mounted on the right outer wall of the battery box 2, a mounting seat 15 is fixedly mounted on the top outer wall and the bottom outer wall of the battery box 2, and a bolt 16 is connected to the internal thread of the mounting seat 15, and the left outer wall of the cover plate 14 is attached to the right outer wall of the battery 3, and a first threaded hole is opened inside the mounting seat 15, and the bolt 16 passes through the internal thread of the cover plate 14 and is connected to the inside of the first threaded hole and is adapted in size.

[0029] The working principle of the above embodiment is:

[0030] When it is necessary to install the battery 3, first install the fully charged battery 3 into the battery box 2. At this time, push the battery 3 to slide inside the battery box 2 so that its left side fits with the right side of the positioning seat 6.

At this time, the installation of the battery 3 is completed. When the brushless saw body 1 is working, the vibration-damping spring 9 will absorb the vibration and slide on the friction plate 10 with a small amplitude. At this time, through the cooperation between the rubber half ring 13 and the vibration-damping spring 9, the vibration on the power connector 4 and the connector 5 is greatly reduced, which improves the stability of the connection.
