<p>A weight assembly mechanism comprises a bracket (12) used for supporting the weight (11), a connecting base (13) fixedly arranged on the weight and a conversion adaptor (14) fixedly arranged on the bracket. A groove track connecting structure used for mounting the connecting base onto the conversion adaptor is arranged between the conversion adaptor and the connecting base. The groove track connecting structure includes a track (141) and a lug boss (131) respectively arranged on the conversion adaptor and the connecting base. A support groove (142) communicated with the track is arranged on the rear end of the track. In operation, the lug boss slides in the track to the rear end of the track, then the lug boss can be locked in the support groove as the weight is turned through a certain angle, so the connection of the conversion adaptor and the connecting base is realized. The defect of rotating the weight for circles in the prior art is avoided.</p> |
