[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1: An auxiliary device for an electric hammer, such as Figure 1-6 As shown, it includes: Mounting frame 1, with a connecting frame 19 fixed on one side of the mounting frame 1, a connecting strap 26 at the bottom of the connecting frame 19, and a first adjusting buckle 25 on the connecting strap 26 for adjusting the effective length of the connecting strap 26. The mounting frame 1 is fixed to the electric hammer body 2 through the connecting frame 19 and the connecting strap 26. The wearable component has a support plate 17, a ball seat 13 is mounted on the top of the support plate 17, a movable ball 21 is movably mounted in the ball seat 13, and two annular arc plates 43 are provided on the inner side of the ball seat 13. The side of the annular arc plate 43 near the movable ball 21 has an arc surface structure; an annular cavity is formed between the two annular arc plates 43, and a fixing member for fixing the movable ball 21 is provided in the annular cavity. A telescopic connecting part is fixed on the movable ball 21, and a second connecting seat 38 is installed at one end of the connecting part; The first connecting seat 33 is installed at the tail of the mounting bracket 1, and the first connecting seat 33 is detachably connected to the second connecting seat 38. The wearable components include: The second strap 8 has matching Velcro straps 7 at both ends; Auxiliary fixing strap 9 is provided on the second binding strap 8, and support plate 17 is fixed to the auxiliary fixing strap 9; The first strap 6 is mounted on the support plate 17 and is provided with a second adjustment buckle 42 for adjusting the effective length of the first strap 6. By setting up the mounting bracket 1, wearable components and other structures, the wearable components can be worn on the body, the support plate 17 can be supported on the shoulder, and the first strap 6 can be passed through the armpit for auxiliary fixation; the first connecting seat 33 and the second connecting seat 38 are connected, so that when in use, the shoulder is used to assist in bearing the force, which reduces the working intensity of the arm to a certain extent. It is well-suited for work at an upward angle, such as working on the ceiling.

[0025] To facilitate the connection between the second connecting seat 38 and the first connecting seat 33; as Figure 4As shown, the first connecting seat 33 is hollow inside, and a circumferentially distributed guide tube 36 is provided on the inner side of one end of the first connecting seat 33.
