[0095] 1. Principle of the connection between two bell pieces: When connecting two bell pieces (assuming one is bell piece a and the other is bell piece b), first, insert the third connecting portion 11 of bell piece a into the second channel 21 of the rear fixing member 2 of bell piece b. At the same time, push the pressing button 41 of bell piece b inward. The pressing button 41 drives the pressing member 42 inward, the second elastic member 44 is compressed, and the pressing member 42 squeezes the first driving portion 311, thereby causing the second connecting member 31 to move to the sides (while the first elastic member 32 is compressed). Wait until the third 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 the bell piece a enters the third limiting groove 22 on the rear fixing member 2 of the bell piece b. The pressing button 41 of the bell piece b 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 second clamping member 31 is reset, and the fourth clamping portion 312 is clamped into the second clamping groove 111 of the third clamping portion 11 of the bell piece b. The first limiting protrusion 314 of the bell piece b is inserted into the corresponding first sliding groove 51. At this time, the two bell pieces are clamped together.

[0096] The principle of the connection between the clamping assembly 9 and the bell piece: First, insert the first clamping portion 911 of the clamping assembly 9 into the second channel 21 of the rear fixing member 2 of the bell piece, and at the same time push the pressing button 41 of the bell piece 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, thereby causing the second clamping member 31 to move to both sides (while the first elastic member 32 is compressed), and the first clamping portion 911 of the lever assembly 8 is completely inserted into the second channel 21 of the rear fixing member 2 of the bell piece. In the second channel 21, the third limiting protrusion 82 on the lever assembly 8 enters the third limiting groove 22 on the rear fixing member 2 of the bell piece, the pressing button 41 of the bell piece is released, and the pressing button 41 retracts under the action of the second elastic member 44. At the same time, under the action of the first elastic member 32, the second clamping member 31 is reset, and the fourth clamping portion 312 is clamped into the first clamping groove 9111 on the clamping assembly 9. The first limiting protrusion 314 of the bell piece is inserted into the corresponding first sliding groove 51. At this time, the bell piece is clamped with the clamping assembly 9.

[0097] When in use, first assemble the first rod 81, the second rod 83 and the pair of clamping assemblies 9, then clamp the bell piece on the first clamping portion 911 of the corresponding first clamping member 91, and then gradually clamp other bell pieces on the outside of the bell piece as needed.

[0098] Above, refer to Figures 1 to 17 The present invention discloses a barbell with a simple structure, low cost and easy folding and unfolding. The barbell has a plurality of plates that can be connected to each other, and has strong adaptability and replaceability. The weight load of the fitness practitioner can be adjusted by adjusting the number of connected plates. At the same time, the weight of a single plate can be controlled by adjusting the mass of the counterweight assembly.
