[0040] I. Principle of engagement between two bells: When engaging two bells (assuming one is bell a and the other is bell b), firstly, insert the third engagement part 11 of bell a into the second channel 21 of the rear fixing member 2 of bell b, and simultaneously push the pressing button 41 of bell b inward. The pressing button 41 drives the pressing member 42 to move inward, compressing the second elastic member 44. The pressing member 42 squeezes the first driving part 311, thereby causing the second engagement member 31 to move to both sides (while the first elastic member 32 is compressed). Wait until the third engagement part 11 of bell a is fully inserted into bell b. Within the second channel 21 of the rear fixing member 2, the second limiting protrusion 15 on the front fixing member 1 of the bell a enters the third limiting groove 22 on the rear fixing member 2 of the bell b. The pressing button 41 of the bell b 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 locking member 31 resets, and the fourth locking part 312 is locked into the second locking groove 111 of the third locking part 11 of the bell b. The first limiting protrusion 314 of the bell b is inserted into the corresponding first sliding groove 51. At this time, the two bells are locked together.

[0041] The engagement principle between the engagement assembly 9 and the bell is as follows: First, the first engagement part 911 of the engagement assembly 9 is inserted into the second channel 21 of the bell rear fixing member 2. At the same time, the pressing button 41 of the bell is pushed inward. The pressing button 41 drives the pressing member 42 to move inward, compressing the second elastic member 44. The pressing member 42 squeezes the first driving part 311, thereby causing the second engagement member 31 to move to both sides (while the first elastic member 32 is compressed). When the first engagement part 911 of the lever assembly 8 is fully inserted into the second channel 21 of the bell rear fixing member 2, the second engagement part 911 moves to both sides. Within 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, releasing the pressing button 41 of the bell. Under the action of the second elastic member 44, the pressing button 41 retracts. At the same time, under the action of the first elastic member 32, the second locking member 31 resets, and the fourth locking part 312 locks into the first locking groove 9111 on the locking assembly 9. The first limiting protrusion 314 of the bell is inserted into the corresponding first sliding groove 51. At this time, the bell is locked with the locking assembly 9.

[0042] In use, first assemble the first rod 81, the second rod 83 and a pair of snap-fit ​​components 9, then snap the bell onto the first snap-fit ​​part 911 of the corresponding first snap-fit ​​component 91, and then snap other bells onto the outside of the bell as needed.

[0043] Above, refer to Figures 1-17 A barbell according to an embodiment of the present invention is described, which has a simple structure, low cost, and is easy to store and take down; multiple weight plates can be interlocked with each other, making it highly adaptable and replaceable; the load on the exerciser can be adjusted by adjusting the number of interlocked weight plates; and the weight of a single weight plate can be controlled by adjusting the mass of the counterweight assembly.
