One end be located near the waist under lying low of the user on backboard 2 under state, being provided with the first described groove 3 can edge
Bar 6 is corrected at the back that the rotation connection of its end coordinates, and the other end that bar 6 is corrected at the back is vertically and fixedly provided with arm locating rod
7, the gap grafting of 7 and second groove of arm locating rod 4 coordinates, and bar 6 and the opposite side of arm locating rod 7 are corrected in the back
Pull bar 8 is fixedly arranged in the middle of, the other end of the pull bar 8 passes through the guide chute 9 slided with its gap to extend in supporting square tube 11
It is connected with spring 10, the other end of the spring 10 is fixed near the end of supporting square tube 11；
The both sides of the upper end of leg fixed mount 5 are symmetrically arranged with is rotatablely connected the positioning pipe 12 of cooperation, the positioning with it
The end of pipe 12 is fixed with connecting rod 13, and the other end between two connecting rods 13 is provided with the counterweight pressing block being closely slidably matched with it
14, the bottom symmetrical of the counterweight pressing block 14 is fixed with positioning depression bar 15.
The end both sides of first groove 3 offer axis hole 31, and the end both sides difference that bar 6 is corrected at the back is outside
Vertically extend the rotating shaft 61 being rotatably assorted with the gap of axis hole 31.
120-135 ° of angle is provided between described back correction bar 6 and pull bar 8.
The end of described supporting square tube 11 is provided with rotary locating button 16.
As a result of above technical scheme, the invention has the advantages that：It is simple in construction, it is easy to use, make
Bar is corrected at back during can be fitted in back, waist and the head of operator all the time, remind the position of operator three to protect
Hold on same straight line, while the arm of operator is opened and is close in arm locating rod, is referred to two and is close near auricle, really
The full open position of upper limbs is protected, it is preferable for iliopsoas and the musculus quadratus lumborum train on of bent hip muscle and dorsal part；Grasp simultaneously
Counterweight pressing block is transferred to the belly of operator when stressing exercising abdominal muscles and carrying out volume abdomen, makes its waist during abdomen is rolled up by author
Vertebra is close to backboard.
