In addition, in the present application, the strap 140 is a flexible material, and the protrusion gap 141 may be adjusted to a size suitable for use by the exerciser. The adsorption member 120 plays a main adsorption role, and the non-slip member 130 is used for assisting in pressing the yoga mat, so that the yoga mat is prevented from sliding.

As shown in fig. 1 and 4, as an embodiment, the sit-up aid 100 further includes a wrench assembly 150, the wrench assembly 150 is connected to the adsorbing member 120, and the wrench assembly 150 is used for controlling the adsorption/desorption between the adsorbing member 120 and the ground. Illustratively, in order to ensure the user's case safety, it is necessary to increase the suction force between the sit-up aid 100 and the ground, however, when the aid 100 is detached after the use of the aid 100, it is difficult to detach the aid 100 by brute force, so that it is necessary to provide a wrench assembly 150 to contact the suction force between the suction member 120 and the ground.

As shown in fig. 4, 5 and 6, as an embodiment, the wrench assembly 150 includes a connecting rod 151 and a wrench member 152, one end of the connecting rod 151 is connected to the suction member 120, the other end is hinged to the wrench member 152, the connecting rod 151 extends from the suction member 120 to the outside of the main body 110, and the wrench member 152 abuts against the main body 110. Illustratively, the connecting rod 151 is a cylindrical stepped shaft overall, the connecting rod 151 includes a connecting portion 1511, a first shaft body 1512 and a second shaft body 1513 which are connected in sequence, wherein the connecting portion 1511 is disc-shaped, the first shaft body 1512 and the second shaft body 1513 are both cylindrical, and in the present embodiment, the diameter of the first shaft body 1512 is larger than that of the second shaft body 1513. The adsorbing member 120 is provided with a first hole 121 and a second hole 122, the aperture of the first hole 121 is slightly larger than the diameter of the connecting portion 1511, so that the connecting portion 1511 can be placed in the first hole 121, the aperture of the second hole 122 is slightly larger than the diameter of the first shaft body 1512, so that the first shaft body 1512 can be placed in the second hole 122, and the aperture of the first hole 121 is larger than the aperture of the second hole 122, so that the connecting portion 1511 cannot pass through the second hole 122, thereby realizing the connection between the connecting rod 151 and the adsorbing member 120.

As shown in fig. 1 and 4, as an embodiment, the wrench member 152 has a cam portion 1521, the cam portion 1521 abuts against the main body 110, and the wrench member 152 is rotated to slide the connecting rod 151 and deform the suction member 120. Illustratively, the principle is that the rotation of the key member 152 is converted into the linear sliding of the connecting rod 151 through a cam structure, and the sliding connecting rod 151 drives the adsorbing member 120 to deform, so as to release the adsorbing effect of the adsorbing member 120 on the ground. In addition, it should be noted that the absorption member 120 is made of a flexible material, and is deformed by an external force, and at this time, the absorption member 120 is not completely attached to the ground, which is equivalent to a weakening of the absorption force, so that the auxiliary device 100 can be removed.
