[0007] The hook at two return spring two ends is hooked in two that two of two secondary shoes upper ends hang the upper and lower ends of spring pin respectively hangs on the spring pins, form two return springs up and down, two cams are positioned in the middle of two return springs.

[0008] The pulling arm frame includes an articulated shaft sleeve and a support arm; the articulated shaft sleeve is nested on the pin shaft, and articulated ear plates are fixedly welded on both sides of the articulated shaft sleeve; one end of the support arm is embedded between the pair of articulated ear plates and the end of the support arm is connected to the articulated ear plates through an articulated shaft, and a clamping plate that cooperates with the latching teeth is vertically provided below the end; an adjustable handle is provided at the other end of the support arm along the vertical direction; the support arm can be driven upward by the adjustable handle to rotate no more than 5° around the hinge to realize the disengagement of the clamping plate from the latching teeth;

[0009] The adjustable handle includes a handle mounting base, a universal ball joint, a side connecting plate and a handle unit; the handle mounting base is arranged at the end of the support arm along the vertical direction; the universal ball joint is installed on the bottom end of the handle mounting base; an extension column is provided at the bottom end of the universal ball joint along the vertical direction, and an annular groove is provided on the extension column; the side connecting plate is L-shaped and has a connecting hole on the side connecting plate, which is nested in the annular groove of the extension column; the handle unit is fixed horizontally at a position near the bottom end of the side connecting plate.

[0010] Furthermore, the latching teeth on the semicircular structure on the side of the lower mounting plate extending out from the edge of the beam have at least fifteen latching grooves, forming at least fifteen gripping positions.

[0011] The advantages of the present invention are:

[0012] 1) The utility model changes the traditional handle structure at the end of the support arm into a handle connected with a universal ball joint; when the handle of this pull arm structure for a fitness frame is in a stressed state, a slight rotation of the wrist can drive the handle unit to adjust in the horizontal position through the universal ball joint, with low resistance and more flexible adjustment, thus meeting the requirement of fine-tuning the rotation of the handle in the pull arm of the fitness frame when under stress; and is more convenient and flexible to use.
