Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

an upper limb retractor comprises a bracket member 1, a pair of connecting members 2 and a pair of traction members 3; the connecting member 2 comprises a rotating rod 21, a cylindrical fixture block 212, a connecting sleeve 22 and hard friction rubber 23; the connecting sleeve 22 is in the shape of a stepped cylindrical shell formed by fixing a small cylindrical shell and a large cylindrical shell together; the outer surface of the hard friction rubber 23 is provided with a hard friction rubber snap groove 231; a handle 211 is fixed at the lower end of the rotary rod 21, and a cylindrical fixture block 212 is fixed at the upper end of the rotary rod 21; the rotary rod 21 is in threaded connection with the large cylindrical shell of the connecting sleeve 22, and the cylindrical fixture block 212 is sleeved in the hard friction rubber clamping groove 231; the clearance between the outer surface of the hard friction rubber 23 and the outer cylindrical end surface of the bracket component 1 can be adjusted through the screw thread between the rotating rod 21 and the large cylindrical shell of the connecting sleeve 22; the connecting member 2 is sleeved on the bracket member 1 through the small cylindrical shell of the connecting sleeve 22, and the lower end of the outer surface of the small cylindrical shell of the connecting sleeve 22 is fixedly connected with the traction member 3, so that the connecting member 2 and the traction member 3 are fixed together.

As shown in fig. 1, the bracket member 1 includes a pillar 11 and a connecting frame 12; the upright post 11 is a hollow cylindrical shell; the connecting frame 12 is in a Z-shaped cylindrical curved rod shape, and the middle position of the connecting frame 12 is fixedly connected with the outer end face of the upright post 11; the small cylindrical shell of the connecting sleeve 22 is sleeved on the cylindrical end surfaces at the two ends of the Z-shaped cylindrical curved rod of the connecting frame 12.

As shown in fig. 1, the pulling member 3 includes a pair of hand pulls 31, a pair of connecting ropes 32, and an arc-shaped beam 33; the middle position of the arc beam 33 is fixedly connected with the outer surface of the small cylindrical shell of the connecting sleeve 22; two ends of the arc-shaped beam 33 are hinged with one end of a connecting rope 32, and the other end of the connecting rope 32 is sleeved with the hand pull 31; the pair of traction members 3 are located on both sides of the upright 11, and the pair of traction members 3 are arranged diagonally offset.

As shown in fig. 1 and 2, the surface of the hand-pulling portion 31 is covered with a rubber skin to prevent the exerciser from slipping.

As shown in fig. 1 and 2, the connection cord 32 is a braided cord to prevent noise.

The exerciser holds the hand pull 31 by both hands, when one hand pulls downwards, the connecting rope 32 sleeved on the hand pull 31 and the arc-shaped beam 33 start to turn relatively, and at the moment, the connecting sleeve 22 in the middle of the arc-shaped beam 33 starts to turn relatively on the outer cylindrical end of the connecting frame 12; the rotary rod 21 on the connecting sleeve 22 also synchronously rotates along with the arc beam 33; when the exercise intensity needs to be adjusted, as the handle 211 is in threaded connection with the connecting sleeve 22, the cylindrical fixture block 212 on the rotating rod 21 can be rotated up and down by rotating the handle 211 with two hands, and meanwhile, the cylindrical fixture block 212 also drives the hard friction rubber 23 to move up and down; when the hard friction rubber 23 moves upwards, the tighter the hard friction rubber 23 is contacted with the outer cylindrical end surface of the connecting frame 12, the larger the hand-pulling exercise force of the exerciser is; when the hard friction rubber 23 moves downward, the looser the hard friction rubber 23 is in contact with the outer cylindrical end surface of the connecting frame 12, the smaller the hand-pulling exercise power of the exerciser.
