A center post 17 can be formed in the middle of the connecting groove 13, the spring 15 is sleeved on the center post, the middle of the rotating gear 14 passes through the center post 17, the connecting head 21 and the connecting groove 13 can be pivoted by a bolt 181 and a nut 182, the bolt 181 passes through a positioning hole 2122 formed in the middle of the pressure groove 212 and then passes through the center post 17, the nut 182 is used for locking, the bolt 181 is locked by the nut 182, and the rotating connection of the connecting head 21 is completed. Meanwhile, the outer end of the connecting portion 11 forms an arc-shaped rib 111, so that the side of the connector 21 can be engaged with the rib for rotation.

For the connection between the two movable plate bodies 10, a joint sleeve 112 may be formed at the inner end of one of the connecting edges 11, a joint head 113 with a flat round head shape may be formed at the inner end of the other connecting edge 11, the joint head 113 with a round disc shape is movably sleeved between the two lugs 1121 of the joint sleeve 112, an arc edge is formed at the outer side of the lug 1121, and an arc rib 1131 attached to the outer side of the lug 1121 is formed at the rear side of the joint head 113. The joint head 113 is connected with the joint sleeve 112 through a screw and a nut, the joint head 113 rotates between the joint sleeve 112, and the joint sleeve 112 moves along the arc-shaped retaining edge at the rear side of the joint head, so that the twisting between the two movable plate bodies 10 can be realized. The arm 2 is a handle, and the rear section of the handle forms a handle portion 21, so that the handle is convenient for a user to hold. The elastic body 3 in this embodiment is an annular elastic drawstring, and the elastic drawstring is sleeved between the two limiting edges 12 to generate tensile resistance.

The utility model discloses during the use, the back location is rotated in the connecting portion to single arm-drag 2, presses button 16, as the state shown in fig. 5, and the running gear 14 who pushes down is in spread groove 13 to can rotate in tooth's socket 131, the connector 21 that drives single arm-drag 2 can rotate. When the pull arm 2 is adjusted to the required position, the button is not pressed any more, the rotating gear 14 is bounced by the restoring force of the spring 15, the rotating gear 14 is positioned between the connecting groove 13 and the circular groove 213 of the connector, the rotating gear 14 is limited between the tooth groove 131 and the tooth groove 211, and the connector 21 is clamped, so that the pull arm 2 is positioned. After the pull arms 2 are rotated, the distance and the opening angle between the two pull arms 2 can be adjusted through the operation, and moreover, the pull arms 2 which are rotated upwards or downwards can be rotated to the same side or different side of the limiting edge 12 for limiting (as shown in fig. 8 and fig. 12), so that the moving directions of the two pull arms 2 can be changed relative to the stretching and rebounding directions of the elastic body 3, the force application directions of the two pull arms are changed, the force application mode is changed, and different stretching exercise purposes are realized.

The utility model discloses can have two kinds of user state at least, as shown in fig. 6 to fig. 9, for the utility model discloses a one of them user state rotates two single arms 2 to the homonymy of spacing limit 12, presses down button 16, turns to one end that is close to spacing limit 12 with single arm-drag 2, rotates to the suitable position back release button, single arm-drag 2 location. During exercise, the two pull arms 2 are stretched outwards, as shown in fig. 6 and 7, and the elastic resistance of the elastic body 3 needs to be overcome during stretching outwards, so that the exercise is realized.
