Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0019] In the present utility model, unless otherwise clearly defined, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication between two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0020] In the present utility model, unless otherwise clearly defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0021] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.
[0022] Please refer to Figures 1 to 4 , the present utility model provides a multi - force grip strengthener, which includes a first main body part 11 and a second main body part 12 integrally formed on the outer periphery of the first main body part 11. The materials of the first main body part 11 and the second main body part 12 are both silica gel, and there is a difference in the hardness between the first main body part 11 and the second main body part 12 to improve the comfort of the hand during use.
[0023] Specifically, the hardness of the second main body part 12 is less than that of the first main body part 11. The hardness of the second main body part 12 is Shore hardness 40 - 60A, and the hardness of the first main body part 11 is Shore hardness 70 - 90A.
[0024] The first main body part 11 includes a connecting section 111 and a main body section 112. The connecting section 111 connects the inner side of the second main body part 12 and the outer side of the main body section 112. A functional hole 13 is provided on the main body section 112. The functional hole 13 is arranged in an elliptical hole shape with a horizontal middle part and arc-shaped transitions on both sides. Among them, the functional hole 13 is arranged at the middle position in the thickness direction of the second main body part 12, and the thickness of the main body section 112 gradually shrinks from outside to inside, so as to form guiding surfaces 113 on both sides in the thickness direction of the main body part. Moreover, on both sides of the first main body part 11 in the short axis direction of the functional hole 13 (indicated by the arrow A in the figure), there are reinforcing parts 114. The thickness at the position of the reinforcing parts 114 is further thickened on the basis of the guiding surfaces 113. By arranging the reinforcing parts 114, when squeezing the multi-strength gripper in the long axis direction (indicated by the arrow B in the figure), the anti-deformation strength of the gripper is increased.
[0025] In addition, to further improve the grip feeling of the user during use, the outer side surface of the second main body part 12 is in an arc-shaped transition in the thickness direction (indicated by the arrow C in the figure), and the second main body part 12 is composed of a plurality of arc-shaped segments connected end to end. In this embodiment, the second main body part 12 is composed of four arc-shaped segments connected end to end.
[0026] During use, the multi-strength gripper of the present utility model can provide various strength trainings. Specifically, it includes squeezing the gripper inward along the short axis direction of the functional hole 13, squeezing the gripper inward along the long axis direction of the functional hole 13, and squeezing the gripper inward along the direction between the long axis and the short axis of the functional hole 13. When squeezing the gripper inward along the short axis direction of the functional hole 13, at this time, the anti-deformation strength of the gripper is relatively small, and the strength requirement for the user during training is relatively easy; when squeezing the gripper inward along the long axis direction of the functional hole 13, at this time, the anti-deformation strength of the gripper is relatively large, and the strength requirement for the user during training is relatively difficult; and when squeezing the gripper inward along the direction between the long axis and the short axis of the functional hole 13, at this time, the training strength is between the long axis training strength and the short axis training strength.
[0027] The beneficial effects of the multi-strength gripper of the present utility model are as follows: By arranging the functional hole 13 in an elliptical hole shape, and there are reinforcing parts 114 on both sides of the first main body part 11 in the short axis direction of the main body section 112. When squeezing the multi-strength gripper in the long axis direction, the anti-deformation strength of the gripper is increased, so that a single gripper can provide various strength trainings. The user can select according to his own actual use needs, with good flexibility and strong practicability.
[0028] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0029] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
