At the same time, a limiting plate 6 is fixedly connected to one end of the extending part 7 away from the positioning plate 5, and the limiting plate 6 is fixedly connected to the corresponding positioning plate 5 through a bolt.

[0018] In this embodiment, when the user needs to use dumbbells for fitness, select a suitable counterweight plate 4 and sleeved it on the surface of the fixing part 2, and then fix the counterweight plate 4 with the fastening block 3. Then the user can perform corresponding dumbbell fitness actions by holding the connector body 1. When the user needs to use a barbell for fitness, first remove the bolt on the limiting plate 6 to release the restriction between the limiting plate 6 and the positioning plate 5, and then pull the two connector bodies 1 to move towards both ends, so that the dual-purpose connector changes from the folded state to the unfolded state. When the two limiting plates 6 are in contact, use bolts and nuts for corresponding fixation. At this time, the dual-purpose connector changes from the dumbbell mode to the barbell mode. The user can also choose whether to replace the counterweight plate 4 according to their own needs, which is convenient for the user to hold the connector body 1 for corresponding barbell fitness actions later, thus reducing the user's purchase cost, reducing the sense of congestion in the room, and facilitating subsequent outdoor carrying, enhancing the practicability of the equipment.
