The end of the rod is screwed with a positioning nut and a cap, the bottom of the cap is pressed against the positioning nut, the bottom surface of the positioning nut is fixed with a self-lubricating ring, and the self-lubricating ring is pressed against the front end of the arc-shaped support block ;

The two ends of the arc-shaped support block are screwed with an upper connector, the bottom of the upper connector is fixed with a chain, and the lower end of the chain is fixed with a handle.

There is a groove on the bottom side wall of the upper support sleeve, the rotating rod is in the groove, the lower end of the rotating rod is hinged on the two side walls of the groove through the hinge shaft, and the rotating rod is fixed on the inner side wall of the groove There are permanent magnets on the block.

A self-lubricating sleeve is inserted into the extension rod, and the self-lubricating sleeve is clamped between the arc-shaped support block and the end surface of the transversely extending column.

The outer wall of the handle is covered with a rubber protection layer.

A self-lubricating copper sleeve is inserted into the socket in the middle part of the arc-shaped support block, and the outer wall of the self-lubricating copper sleeve is fixed on the inner wall of the socket.

The outstanding effect of the present invention is: compared with the prior art, it realizes the adjustment by rotating the upper support sleeve, the adjustment is convenient, the height adjustment range is large, and the effect is good.

detailed description:

For an embodiment, as shown in Figures 1 to 3, a vertically adjustable upper limb traction device includes a base 10, which is fixed on the ground, and the middle part of the top surface of the base 10 has an upwardly extending screwed extension column 11, The middle part of the bottom surface of the upper support sleeve 12 has a screw connection hole 121, and the screw connection extension column 11 is screwed in the screw connection hole 121. The upper two sides of the upper support sleeve 12 are fixed with a horizontal extension column 13, and the end surface of the horizontal extension column 13 There is an extension rod 14 in the middle, and the extension rod 14 is inserted into the socket 151 provided in the middle of the arc support block 15. The end of the extension rod 14 is screwed with a positioning nut 141 and a block cap 142, and the bottom end of the block cap 142 is connected to the positioning nut. 141 is pressed against each other, and the bottom end surface of the positioning nut 141 is fixed with a self-lubricating ring body 149, and the self-lubricating ring body 149 is pressed against the front end surface of the arc-shaped support block 15;

Both ends of the arc-shaped support block 15 are screwed with an upper connector 16 , the bottom of the upper connector 16 is fixed with a lock chain 17 , and the lower end of the lock chain 17 is fixed with a handle 18 .
