[0022] Please refer to Figures 2 to 3In order to adjust the height of the instrument, the adjustment mechanism 7 in this embodiment includes a sleeve 701 fixed to the upper surface of the adjustment block 5. The inner cavity of the sleeve 701 is provided with an inner support rod 702. A hinge seat 703 is fixed to the top of the left side of the inner support rod 702. A connecting rod 704 is hinged to the top of the inner cavity of the hinge seat 703. A sliding cylinder 705 is slidably connected to the outer surface of the connecting rod 704. A bearing rod 706 is fixed to the right end of the lower surface of the connecting rod 704. A moving cylinder 707 is slidably connected to the top of the outer surface of the bearing rod 706. An inclined mounting rod 708 is fixed to the top of the left side of the bearing rod 706. A sleeve rod 709 is fixed to the left end of the upper surface of the mounting rod 708.

[0023] The adjustment mechanism 7 includes multiple insertion holes 710 located on the right side of the inner support rod 702, the left end of the upper surface of the connecting rod 704, and the left end of the bearing rod 706. A rod 711, with one end extending through and into the inner cavity of the insertion hole 710, is slidably connected to the top right side of the sleeve 701, the top of the sliding cylinder 705, and the left side of the moving cylinder 707. A return spring 712 is movably fitted onto the outer surface of the rod 711. A star-shaped handle is fixed to the other end of the rod 711. The two ends of the return spring 712 are fixedly connected to the sleeve 701, the sliding cylinder 705, and the side of the moving cylinder 707 opposite to the star-shaped handle, respectively. By pulling the star-shaped handle, the rod 711 is disengaged from the insertion hole 710, releasing the inner support rod 702 from its limit. This allows the height of the inner support rod 702 to be adjusted to a suitable height. Releasing the handle causes the return spring 712 to retract and move the rod 711 back into the insertion hole 710, thus locking the position and height of the inner support rod 702.

[0024] In this embodiment, the tops of the inner support rod 702, the sliding cylinder 705, and the moving cylinder 707 on both the front and rear sides are all fixed with circular cylinders, which are rubber cylinders. The positions of the other two distributed circular cylinders can be adjusted to accommodate users with different needs. Users can lie or sit on the dumbbell bench and push the circular cylinders with their leg strength to perform leg extension and bending exercises. Different training intensities and postures can be adjusted according to individual needs. The outer surface of the sleeve rod 709 is movably fitted with a spring clip. The left end of the upper surface of the bearing rod 706 is fixed with a connecting ring. The dumbbell is put on the outer surface of the sleeve rod 709, and then the spring clip is used to put it on the sleeve rod 709 to limit and fix the vertical position of the dumbbell.

[0025] It should be noted that the height of the equipment and the position of the cylinder can be freely adjusted by people of different heights. It can also effectively exercise leg and back muscles. The operation process is relatively simple and easy for users to use.

[0026] The working principle of the above embodiments is as follows:

[0027] (1) When in use, the user can hold the U-shaped handle with one hand and the sleeve 701 with the other hand, and then pull the U-shaped handle upward so that the pulley 3 contacts the ground, so that the equipment can be easily moved to the required position by using the pulley 3. The equipment is then supported by two L-shaped support blocks 1 and positioning plate 6. At this time, the two pulleys 3 are supported, ensuring the stability of the equipment. The adjustment mechanism 7 is used to adjust the height and horizontal position of the leg support to adapt to the height and leg extension needs of different users. At the same time, it allows various dumbbell bench accessories to be quickly assembled with various dumbbell benches without the dumbbell bench itself having a structure for fixed installation accessories. By simply using this independent base, different forms of the base can be switched to realize the functions of various accessories.

[0028] (2) Place the dumbbell bench on the right side of the positioning plate 6. At this time, according to the training needs, the dumbbells can be put on the outer surface of the bar 709, and then the spring clip can be used to put the dumbbells on the bar 709 to limit the position. When adjusting the height, the user can pull the star handle to make the insertion rod 711 exit from the insertion hole 710, which can release the limit of the inner support rod 702, thereby adjusting the height of the inner support rod 702 to a suitable height. Release the handle, the return spring 712 retracts and drives the insertion rod 711 to move back into the insertion hole 710, which can lock the position height of the inner support rod 702. The above adjustment method can adjust the position of the other two distributed cylinders to adapt to the needs of different users. The user lies or sits on the dumbbell bench and pushes the cylinder with the strength of the legs to perform leg extension and leg bending training, and can adjust different training intensities and postures according to individual needs.
