[0028] Example 2

[0029] Reference Figures 2-3 On the basis of example 1, the improvement is that in order to improve the stability of the fixing, a plurality of limiting plates 12 are further fixed on one side of the fixing disc 5. The limiting plates 12 are respectively located in the plurality of installation grooves 16 on the same side, and cooperate with the plate hammer body 3 and the plate hammer seat 4 to further fix the plate hammer body 3.

[0030] In order to realize the positioning effect, a plurality of first clamping strips 6 are fixed on one side of the plate hammer body 3, and a plurality of second clamping strips 13 are fixed on one side of the limiting plate 12. The first clamping strips 6 and the second clamping strips 13 can cooperate with each other to further enhance the fixing effect of the plate hammer body 3, and the position adjustment is realized by clamping the second clamping strips 13 to different positions of the plurality of first clamping strips 6.

[0031] In order to prevent the plate hammer body 3 from falling off during positioning and ensure safety, a limiting side groove 8 is arranged on the inner wall of the clamping groove 9, and a limiting strip 7 is fixed on one side of the installation groove 16.
