[0033] Specifically, if Figure 4-6 As shown, the bracket 1 of this embodiment includes a main frame 11, the rear end of the main frame 11 is connected to the rear support assembly 2, the front end of the main frame 11 is connected to the front support assembly 4, and a motor 5 and an electronic control assembly 52 are provided below the main frame 11 near the front support assembly 4. A column 12 is provided above the front end of the main frame 11, and a reversing wheel 13 is hinged on the column 12. The webbing 7 is connected to the reversing wheel 13 to reverse the webbing 7, thereby facilitating the armrest 6 to pull the webbing 7 to perform reciprocating motion.
[0034] It is worth noting that during the reciprocating motion of the webbing 7, especially when the webbing 7 is rapidly retracted, it is prone to becoming tangled or even knotted at the reversing wheel 13. To address the problem of stable retraction of the webbing 7, a pinch roller 14 is provided on the column 12 of this embodiment. The pinch roller 14 is located above the reversing wheel 13 and contacts the webbing 7, thereby providing guidance and limiting for the webbing 7 during its reciprocating motion, thereby preventing the webbing 7 from becoming tangled or even knotted. The pinch roller 14 of this embodiment is sleeved on a movable shaft 15. The column 12 is provided with a slot, and the movable shaft 15 is plugged into the column 12.
[0035] Preferably, to further enhance the guiding and limiting effect of the pinch roller 14 on the webbing 7 without adding additional resistance to the webbing 7, the pinch roller 14 is connected to an elastic component 16. The elastic component 16 can drive the pinch roller 14 to compress the webbing 7 in real time. In this embodiment, the elastic component 16 is a tension spring, one end of which is connected to the column 12 and the other end is connected to the movable shaft 15. The slot is an elongated hole, allowing the movable shaft 15 to move within the slot, thereby allowing the pinch roller 14 to compress the webbing 7 in real time. To improve the reliability and stability of the pinch roller 14 during operation, two tension springs are preferably symmetrically arranged on either side of the column 12.
[0036] like Figure 1 and Figure 7 As shown, to facilitate the placement of the armrest 6, an armrest base 61 is provided on the chain cover 3. The armrest base 61 is positioned near the reversing wheel 13. A slot 62 is provided on the armrest base 61. The armrest 6 can be snapped into the slot 62 of the armrest base 61 to facilitate the placement of the armrest 6.

A support pad 42 is provided at one end of the front side of the chain cover 3 away from the front support assembly 4. The resistance rowing machine can lift the bracket 1 with the roller 41 as a fulcrum so that the support pad 42 touches the ground, and then fold the rear support assembly 2 to realize the folding and storage of the resistance rowing machine, thereby reducing the space occupied by the resistance rowing machine.
[0038] In order to improve the stability of the resistance rowing machine when it is folded and stored, a support frame 43 is provided on the column 12, and a support opening 32 is provided on the chain cover 3. The support pad 42 is connected to the support frame 43 through the support opening 32, thereby improving the support strength of the support pad 42 and preventing the chain cover 3 from being crushed or damaged by direct contact with the ground.
[0039] The rear support assembly 2 includes a rear shield 21 and rear legs 22. The rear shield 21 is fixed to the rear end of the main frame 11. The rear legs 22 are hinged to the rear shield 21. The rear legs 22 can rotate relative to the rear shield 21 to achieve folding of the rear legs 22. It is worth noting that in order to improve the reliability of the rear legs 22 when in use, the rear shield 21 is provided with a locking assembly, which can lock the rear legs 22 to prevent the rear legs 22 from rotating and folding relative to the rear shield 21.
[0040] The locking assembly includes a T-shaped knob 23. The rear shield 21 is provided with a locking hole. The T-shaped knob 23 passes through the locking hole and is threadedly connected to the rear leg 22, thereby locking the rear leg 22. Rotating the T-shaped knob 23 to separate the T-shaped knob 23 from the rear leg 22 can unlock the rear leg 22, allowing the rear leg 22 to be folded and stored.
