[0080] 1. Principle of the connection between two bell pieces: When two bell pieces are connected (assuming that one is bell piece a and the other is bell piece b), first, the second connecting portion 11 of bell piece a is inserted into the second channel 21 of the rear fixing member 2 of bell piece b, and at the same time, the pressing button 41 of bell piece b is pushed inward, the pressing button 41 drives the pressing member 42 to move inward, the second elastic member 44 is compressed, and the pressing member 42 squeezes the first driving portion 311, so that the first connecting member 31 moves to both sides (while the first elastic member 32 is compressed), and the second connecting portion 11 of bell piece a is completely inserted into bell piece b. The second limiting protrusion 15 on the front fixing member 1 of bell piece a enters the third limiting groove 22 on the rear fixing member 2 of bell piece b, the pressing button 41 of bell piece b is released, and the pressing button 41 retreats under the action of the second elastic member 44. At the same time, under the action of the first elastic member 32, the first clamping member 31 is reset, and the third clamping portion 312 is clamped into the second clamping groove 111 of the second clamping portion 11 of the bell piece b. The first limiting protrusion 314 of bell piece b is inserted into the corresponding first sliding groove 51. At this time, the two bell pieces are clamped.

[0081] The clamping principle between the handle 8 and the bell plate: First, insert the first clamping portion 82 of the handle 8 into the second channel 21 of the rear fixing member 2 of the bell plate, and at the same time push the pressing button 41 of the bell plate inward, the pressing button 41 drives the pressing member 42 to move inward, the second elastic member 44 is compressed, and the pressing member 42 squeezes the first driving portion 311, so that the first clamping member 31 moves to both sides (at the same time the first elastic member 32 is compressed), and when the first clamping portion 82 of the handle 8 is completely inserted into the second channel 21 of the rear fixing member 2 of the bell plate ... and the second elastic member 44 is compressed, and the pressing member 42 squeezes the first driving portion 311, and the first clamping member 31 moves to both sides (at the same time the first elastic member 32 is compressed), the first clamping portion 82 of the handle 8 is completely inserted into the second channel 21 of the rear fixing member 2 of the bell plate, and the pressing member 42 is pressed inward. The bell is pressed into the third limit groove 21, and the third limit protrusion 84 on the handle 8 enters the third limit groove 22 on the rear fixing member 2 of the bell plate. The pressing button 41 of the bell plate is released, and the pressing button 41 is retracted under the action of the second elastic member 44. At the same time, under the action of the first elastic member 32, the first clamping member 31 is reset, and the third clamping portion 312 is clamped into the first clamping groove 821811 on the handle 8. The first limit protrusion 314 of the bell plate is inserted into the corresponding first slide groove 51. At this time, the bell plate is clamped with the handle 8.

[0082] When in use, the bell piece is first clamped on the first clamping portion 82 at the lower end of the handle 8, and then other bell pieces are gradually clamped on the outer side of the bell piece as needed.
