A vertical first waist-shaped groove 5 is provided on the arc-shaped plate 4. The first waist-shaped groove 5 on the arc-shaped plate 4 is connected to the trimmer body 2 through a first handle bolt 6. A clamping block 26 is provided between the first handle bolt 6 and the arc-shaped plate 4. The clamping block 26 is provided with a center hole. The first handle bolt 6 passes through the clamping block 26 and the arc-shaped plate 4 in sequence to be connected with the trimmer body 2. The first handle bolt 6 between the first handle bolt 6 and the arc-shaped plate 4 passes through a spring 27 located in the clamping block 26.

[0021] The trimmer body 2 includes a handle 7 and a head 8 connected to the front end of the handle 3. The front end of the handle 7 is connected to a rubber-coated handle 31. The head 8 includes a head support body 9 connected to the arc plate 4 through a first handle bolt 6. The head support body 9 is fan-shaped. A drive motor is installed in the handle 3. The output end of the drive motor is connected to an output shaft 11 that is vertically downward and located at the front end of the handle 3. The front end of the handle 4 is connected to the head support body 9 and passes downward through the head support body 9. The lower end of the output shaft 11 is connected to a woodworking saw blade 12. As a further explanation of this embodiment, the handle 3 with a drive motor and an output shaft vertically downward is a mature commercial product. For example, it can be but is not limited to the handle of an electric angle grinder in the prior art.

[0022] In this embodiment, a circular groove is provided at the bottom center of the woodworking saw blade 12, and an outer clamping plate 28 is provided in the circular groove. The woodworking saw blade 12 is flush with the bottom surface of the outer clamping plate 28. The outer clamping plate 28, the woodworking saw blade 12, and the output shaft 11 are connected by countersunk bolts 29. An inner clamping plate 30 is also clamped between the output shaft 11 and the woodworking saw blade 12. The inner clamping plate 30 cooperates with the outer clamping plate 28 to clamp the woodworking saw blade 12.

[0023] The outer end of the head support body 9 is provided with a folded edge which is bent downward by 90 degrees and covers the outer periphery of the woodworking saw blade 12, and the woodworking saw blade is a 36-tooth woodworking saw blade.

[0024] A depth gauge 14 is provided in front of the head support body 9, and the depth gauge 14 is also located in front of the handle 4. The depth gauge is a straight plate 10 that forms a T-shaped structure with the handle 7. Both ends of the straight plate 10 are provided with bending sections bent toward the rear. One side of the bottom end of the straight plate 10 is provided with a bending portion 15 bent toward the rear by 90°. The bending portion 15 is provided with a second waist-shaped groove 16 arranged in the front-to-back direction. The second waist-shaped groove 16 of the bending portion 15 is connected to the head support body 9 by a second handle bolt 17.

[0025] A protruding annular flange 18 is provided at the bottom center of the head support body 9, and the output shaft 11 extends into the annular flange 18 and is connected to the woodworking saw blade 12.
