[0021] Please refer to Figures 1-5The utility model provides a spring tensioner, including handle mechanism 1, buckle 2 is installed on handle mechanism 1, spring 3 is installed on buckle 2.

[0022] Further, the handle mechanism 1 includes a handle bar 101, the left and right ends of the handle bar 101 are fixedly installed with a plate body 102, the opposite side of the plate body 102 is fixedly installed with a mounting rod 103, the left and right sides of the surface of the mounting rod 103 are fixedly installed with a mounting hook 104 through bolts.

[0023] Further, the mounting hook 104 is installed with a mounting plate 105, and the buckle 2 is sleeved on the mounting hook 104 or the mounting plate 105.

[0024] Further, the number of the handle mechanism 1 is two, and the handle mechanism 1 is installed at the front and rear ends of the spring 3.

[0025] Further, the left and right ends of the mounting plate 105 are provided with a hook hole 106, and the mounting hook 104 is sleeved on the hook hole 106.

[0026] Further, the mounting plate 105 is provided with an assembly hole 107, and the buckle 2 is sleeved on the assembly hole 107.

[0027] Further, when the front and rear sides of the mounting plate 105 are parallel, the number of the assembly hole 107 is several.

[0028] Further, when the front and rear sides of the mounting plate 105 are arc-shaped, the number of the assembly hole 107 is one, and the assembly hole 107 is located at the center of the mounting plate 105.

[0029] By setting the handle mechanism 1, different numbers of springs 3 can be installed to assist users to exercise with different intensities, the handle mechanism 1 and the spring 3 can be flexibly combined to exercise with both hands or one hand, and the flexibility in use is improved. When the use resistance of the spring tensioner needs to be adjusted, different numbers of springs 3 are installed on the opposite side of the two handle mechanisms 1, the buckle 2 is installed on the mounting hook 104 when the exercise intensity of the user is small, the two springs 3 are installed, the user stretches the two springs 3 through the handle mechanism 1 to exercise the muscles, and when the spring 3 is stretched through the handle mechanism 1, the user places the hands on the handle bar 101, holds the handle mechanism 1 through the handle bar 101, the mounting hook 104 moves synchronously through the plate body 102 and the mounting rod 103 during the movement of the handle bar 101, and the buckle 2 and the spring 3 move through the mounting hook 104 and the mounting plate 105 to stretch the spring 3.
