Therefore, when the motor 24 is started, the power output from the motor 24 is transmitted to the drum 23 via the speed reducer 22, and the drum 23 is rotated in the normal direction or the reverse direction.
One end of the pulling rope 30 is used for being grabbed by a user, and the other end of the pulling rope 30 is connected with the winding drum 23, so that the pulling rope 30 can be pulled by the winding drum 23 to be wound on the winding drum 23 on one hand, and can be pulled by the user to be released from the winding drum 23 on the other hand, and the winding drum 23 is driven to rotate in the releasing process.
As shown in fig. 1 and 2, the braking unit 40 has a push rod 41 and a braking member 44 in this embodiment. The middle part of the push rod 41 is pivoted on a pivoting block 47, the pivoting block 47 is fixedly arranged on one side of the front vertical plate 214, the push rod 41 is provided with an operation end 42 and a driving end 43, wherein the driving end 43 is provided with a convex part 432 and a long groove 434 adjacent to the convex part 432; the brake 44 is a lever in the present embodiment and has a coupling end 45 and a brake end 46, wherein the coupling end 45 has a notch 452 and a stop wall 454 adjacent to the notch 452, and the coupling end 45 of the brake 44 engages with the driving end 43 of the push rod 41 through the notch 452 on the one hand and is connected with the driving end 43 of the push rod 41 through a pin 48 inserted into the slot 434 on the other hand. Therefore, the brake 44 can be driven by the push rod 41 to move along the radial direction of the drum 23 between the braking position P1 shown in fig. 3 and the releasing position P2 shown in fig. 4, when the brake 44 is located at the braking position P1, the brake 44 is pressed against the outer peripheral surface of the drum 23 by the braking end 46, so that the drum 23 cannot rotate arbitrarily when not driven by the motor 24, and in this case, the protrusion 432 of the push rod 41 is pressed against the blocking wall 454 of the brake 44, so that the push rod 41 is positioned to avoid being loosened by an improper external force; conversely, when the brake members 44 are in the release position P2, the braking ends 46 of the brake members 44 are separated from the outer peripheral surface of the drum 23, so that the drum 23 can be driven to rotate by the motor 24. In addition, the brake piece 44 can be movably arranged through a guide sleeve 49, the guide sleeve 49 is fixedly arranged on the rear side surface of the front vertical plate 214, and the guide sleeve 49 provides a guide effect for the brake piece 44 so as to improve the stability and smoothness of the brake piece 44 during actuation.

As shown in fig. 8, the pull-cord type resistance mechanism 14 according to embodiment 3 of the present invention is substantially the same in structure as that of embodiment 2, and the main difference is that the structure of the brake unit 60 is different. Further, as shown in fig. 8 and 9, the brake unit 60 in this embodiment has a solenoid valve 61, a brake plate 62, three sliding posts 63 and a brake piece 64, wherein: the electromagnetic valve 61 is positioned outside the motor seat 21; the brake plate 62 is located in the motor seat 21 and connected to the electromagnetic valve 61 by the sliding posts 63 penetrating the front vertical plate 214; the brake member 64 is a disc in this embodiment and is connected to the brake plate 62 at the outer side thereof, in this embodiment, one end of the shaft 26 is rotatably inserted through the front vertical plate 214, the other end of the shaft 26 is connected to the inner ring 252 of the bearing 25, and the outer ring 254 of the bearing 25 is connected to the drum 23, so that the drum 23 is supported by the bearing 25. Therefore, the electromagnetic valve 61 drives the sliding posts 63 to drive the brake plates 62, so that the brake plates 62 synchronously drive the brake members 64, and thus the brake members 64 can be operated along the axial direction of the drum 23 between the braking position P1 shown in fig. 9 and the releasing position P2 shown in fig. 10, when the brake members 64 are located at the braking position P1, the inner side surfaces of the brake members 64 abut against the outer end surface of the drum 23, so that the drum 23 cannot be rotated arbitrarily when not driven by the motor 24, and when the brake members 64 are located at the releasing position P2, the inner side surfaces of the brake members 64 are away from the outer end surface of the drum 23, so that the drum 23 can be driven by the motor 24 to rotate.
As described above, after the motor 24 is turned off, the brake member 64 is driven to the braking position P1 shown in fig. 9 by the solenoid 61, so that the drum 23 cannot rotate under the action of the brake member 64, and thus the pull rope 30 is prevented from being easily pulled out after the motor 24 is turned off. When the pull rope 30 is to be operated again, the brake member 64 is moved back to the release position P2 shown in fig. 10 by the solenoid 61, and then the motor 24 is started, so that the motor 24 drives the drum 23 to pull or release the pull rope 30, thereby providing a suitable resistance to the user and further achieving the exercise effect.
