In the present embodiment, a gap is provided between the first connecting member 130 and the second connecting member 230, thereby preventing the first stand 100 and the second stand 200 from interfering with each other during the folding process of the strength training machine. Wherein, the opposite ends of the first connecting member 130 and the second connecting member 230 may be provided with chamfers, such as round chamfers, and the first bracket 100 and the second bracket 200 may be prevented from interfering with each other during the folding process of the strength training machine.

In order to firmly connect the first and

second brackets

100 and 200, the first and

second brackets

100 and 200 are prevented from being offset by rotating about the connection handle 310. In some embodiments, the first connector assembly 300 further includes two third connectors 320, the third connectors 320 being hinged with the first and

second connectors

130, 230 located on the outside.

Specifically, the first bracket 100 has a first connecting member 130 on opposite sides thereof, and the second bracket 200 has a second connecting member 230 on opposite sides thereof. A third link 320 is hinged to the second link 230 on the first side of the first bracket 100 and simultaneously is hinged to the second link 230 on the first side of the second bracket 200. The other third link 320 is hinged with the second link 230 of the second side of the first bracket 100 and simultaneously is hinged with the second link 230 of the second side of the second bracket 200. The hinge structure of the third connector 320 and the first connector 130 and the second connector 230 may be the same as the hinge structure of the connecting portion 312 and the first connector 130 and the second connector 230, and will not be described herein.

In some embodiments, the first connector 130 and/or the second connector 230 on the outside further have a stop 700 thereon. When the strength training machine is unfolded, the limiting member 700 abuts against the surface of the third connecting member 320 facing the use side of the weight mechanism 400, i.e., the limiting member 700 abuts against the surface of the third connecting member 320 facing the top of the first bracket 100 or the second bracket 200. Thus, the first and

second brackets

100 and 200 are prevented from being folded back while providing a limit for the deployment strength training machine. In particular implementations, the stop 700 may be a cylinder or a stop block.

The strength trainer concentrates the stress points on the first link 130 and the second link 230 during the folding process, and thus, the support 1000 may be provided to increase the strength of the first link 130 and the second link 230. Specifically, at least one adjacent two first connecting members 130 and at least one adjacent two second connecting members 230 are connected by the support 1000. Thereby, the strength of the first and

second connection members

130 and 230 is increased, and deformation of the first and

second connection members

130 and 230 during folding of the strength training machine is avoided.
