By adjusting the circumferential position of the elastic unit on the handle, different parts of the finger muscles can be exercised; moreover, for hands of different sizes, the circumferential position of the elastic unit can be adjusted within the arc-shaped groove to accommodate different hand sizes, making it highly practical.

[0007] In a preferred embodiment of this utility model, the hand-held part is a stick or a ball.

[0008] The above-mentioned technical solution, with its rod or sphere structure, is easy to hold.

[0009] In a preferred embodiment of this utility model, the handheld part has a double-layer structure, with the inner shell being rigid plastic and the outer layer being flexible elastic material.

[0010] The above technical solution uses an inner shell for support and an outer layer made of elastic material for good comfort.

[0011] In a preferred embodiment of this utility model, there are five arc-shaped grooves, four of which are arranged side by side on one side of the outer periphery of the hand grip, and the other arc-shaped groove is arranged on the opposite side of the outer periphery of the hand grip.

[0012] The above technical solution has four arc-shaped grooves corresponding to the index, middle, ring, and little fingers of the hand, and an arc-shaped groove on the opposite side corresponding to the thumb. The arc-shaped grooves are set on both sides, which can shorten the length of the arc-shaped grooves and improve the strength of the hand.

[0013] In a preferred embodiment of the present invention, the elastic unit includes a seat body slidably connected in an arc-shaped groove and an elastic protrusion extending beyond the hand-held part connected to the seat body. The fixing unit is connected to the seat body and fixes it in the arc-shaped groove. The elastic protrusion is made of a flexible elastic material. Alternatively, the elastic protrusion has a double-layer structure, with the inner shell being a rigid plastic and the outer layer being a flexible elastic material.

[0014] In the above technical solution, the elastic unit consists of a base and an elastic protrusion. The base supports the elastic protrusion, which acts on the finger and utilizes its elastic deformation and recovery to exercise the finger muscles.

[0015] In another preferred embodiment of the present invention, the two side walls of the arc-shaped groove have sliding grooves extending along their length direction, and the two sides of the seat have sliding pins that are engaged in and slide in the sliding grooves. The fixing unit includes a stud that is threadedly connected to the seat. The tail of the stud can abut against the bottom of the arc-shaped groove. By rotating the stud, the upper end face of the sliding pin can abut against the top side wall of the sliding groove.

[0016] In the above technical solution, the sliding column and sliding groove play a guiding role, making the sliding of the seat body in the arc groove smoother.

[0017] In another preferred embodiment of the present invention, the top of the stud is fixedly connected to the bottom of the elastic protrusion as a whole, or the stud is set independently of the elastic protrusion.

[0018] In the above technical solution, when the stud and the elastic protrusion are fixed together, the elastic protrusion acts as a handle, making the rotation of the stud more convenient.

[0019] In another preferred embodiment of the present invention, when the top of the stud and the bottom of the elastic protrusion are fixedly connected as one piece, a washer sleeved on the stud is pressed between the top of the seat and the bottom of the elastic protrusion; when the stud is set independently of the elastic protrusion, a washer sleeved on the stud is pressed between the top of the seat and the head of the stud.

[0020] The above technical solution increases the fastening effect of the stud by setting a shim, thus preventing the seat from loosening.

[0021] In another preferred embodiment of the present invention, when the top of the stud and the bottom of the elastic protrusion are fixed together, the stud has a plurality of hooks arranged circumferentially, and a flexible rope is fixed to one end of the arc groove along its length. The flexible rope is at least inserted into one of the hooks and then fixed to the other end of the arc groove along its length.

[0022] The above technical solution increases the fastening effect of the stud by setting up flexible ropes and hooks, thus preventing the seat from loosening.

[0023] In another preferred embodiment of this utility model, the flexible rope is an elastic rope or a steel wire rope.

[0024] The above technical solutions, using elastic ropes and steel wire ropes, meet the functional requirements, are readily available, and are low in cost.

Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0038] This utility model provides a hand exercise elastic device, such as... Figures 1-4 As shown, in a preferred embodiment, the hand exercise elastic device includes a hand grip 10 for the user to hold, and at least five elastic units 20 disposed around the outer periphery of the hand grip 10 that correspond to the user's fingers. The hand grip 10 is a rod or a ball. Figure 1 The handle 10 shown is a cylindrical rod. Several circumferentially extending arc-shaped grooves 11 are provided on the handle 10 at intervals along its length. At least one elastic unit 20 is slidably connected in each arc-shaped groove 11. A fixing unit 30 for fixing the circumferential angle between the elastic unit 20 and the handle 10 is installed on the handle 10.

[0039] Adopting such a technical solution, such as Figures 2-4As shown, users first release the fixation of the elastic unit 20 by operating the fixing unit 30. Then, according to the training needs, they adjust the circumferential position of the elastic unit 20 in the arc groove 11 and fix it in place by the fixing unit 30. After adjusting all the elastic units 20 to the appropriate position, they hold the hand part 10, and the elastic unit 20 acts on their fingers. By alternately gripping and relaxing, the elastic deformability and recovery deformation of the elastic unit 20 can be used to exercise the muscles corresponding to the elastic unit 20.

[0040] for example Figure 2 As shown, this hand-exercising elastic device can exercise the muscles corresponding to the first phalanx of the right thumb and the first phalanx of other fingers; for example... Figure 3 As shown, this hand-exercising elastic device can exercise the muscles corresponding to the first phalanx of the right thumb and the second phalanx of other fingers; for example... Figure 4 As shown, this hand exercise elastic device can exercise the muscles corresponding to the second phalanx of the right thumb and the third phalanx of other fingers; and by flipping and rotating the hand holding part 10, it can also be used for left-hand exercise, so that the hand exercise elastic device can be used by both hands.

[0041] It should be noted that the number of finger phalanges exercised for all fingers may be the same or different, and should be adjusted according to the actual situation. For example, when exercising the second phalanx of the index finger, the third phalanx of the middle finger can be exercised.

[0042] This embodiment uses five arc-shaped grooves 11 as an example for explanation. Each arc-shaped groove 11 contains one elastic unit 20, corresponding to the five fingers of the hand. Four arc-shaped grooves 11 are arranged side by side on one side of the outer periphery of the hand-holding part 10, corresponding to the index, middle, ring, and little fingers. The other arc-shaped groove 11 is located on the opposite side of the outer periphery of the hand-holding part 10, corresponding to the thumb. Two or more elastic units 20 can also be set in one arc-shaped groove 11. For example, two elastic units 20 can be set in the arc-shaped groove 11 corresponding to the thumb, thereby simultaneously exercising the muscles corresponding to the two phalanges of the thumb. In addition, depending on the situation, the number of arc-shaped grooves 11 can also be set to six, which is suitable for exercising hands with six fingers.

[0043] In another preferred embodiment, the handheld part 10 has a double-layer structure, with the inner shell being a rigid plastic and the outer layer being a flexible elastic material, such as sponge, silicone, or rubber, for better comfort.

[0044] Combination Figure 4As shown, in this invention, the elastic unit 20 includes a seat 21 slidably connected in an arc-shaped groove 11, and an elastic protrusion 22 extending out of the handheld part 10 and connected to the seat 21. A fixing unit 30 is connected to the seat 21 and fixes it in the arc-shaped groove 11. By sliding the seat 21 in the arc-shaped groove 11, the position of the elastic unit 20 in the arc-shaped groove 11 can be adjusted. When the user holds the handheld part 10, the elastic protrusion 22 acts on the fingers, utilizing its elastic deformation and recovery to exercise the finger muscles. The elastic protrusion 22 is made entirely of a flexible elastic material, such as rubber or silicone; or the elastic protrusion 22 has a double-layer structure, with an inner shell of rigid plastic and an outer layer of flexible elastic material.

[0045] like Figure 5 As shown, in another preferred embodiment, the two side walls of the arc-shaped groove 11 have sliding grooves 12 extending along their length direction, which communicate with the arc-shaped groove 11. The two sides of the seat 21 have sliding posts 23 that engage with and slide within the sliding posts 12. Guided by the sliding posts 23 and the sliding grooves 12, the sliding of the seat 21 is smoother. The fixing unit 30 includes a stud 31 threadedly connected to the seat 21. The tail of the stud 31 abuts against the bottom of the arc-shaped groove 11. By rotating the stud 31, the upper end face of the sliding post 23 abuts against the top side wall of the sliding groove 12, thereby fixing the seat 21 in the arc-shaped groove 11.

[0046] In this invention, the top of the stud 31 is integrally connected to the bottom of the elastic protrusion 22, or the stud 31 is set independently of the elastic protrusion 22. Preferably, the stud 31 and the elastic protrusion 22 are integrally connected. Since the elastic protrusion 22 protrudes beyond the handgrip 10 and can function as a handle, the seat 21 can be fixed in the arc-shaped groove 11 by rotating the elastic protrusion 22, thereby fixing the elastic unit 20 in the circumferential position of the handgrip 10.

[0047] More preferably, when the top of the stud 31 is fixedly connected to the bottom of the elastic protrusion 22 as a single unit, a washer 32 sleeved on the outside of the stud 31 is pressed between the top of the seat 21 and the bottom of the elastic protrusion 22. The washer 32 can be a rubber pad or a spring sheet to increase the fastening effect of the stud 31 and prevent the seat 21 from loosening. When the stud 31 is set independently of the elastic protrusion 22, a washer 32 sleeved on the outside of the stud 31 is pressed between the top of the seat 21 and the head of the stud 31.

[0048] like Figure 6As shown, in another preferred embodiment, each elastic protrusion 22 is provided with a ring 24 that can be fitted onto a finger. The ring 24 is an elastic band or an adjustable plastic band (similar in structure to an adjustable ring). When using this elastic device, the finger is inserted into the corresponding ring 24, which then holds the finger in place. During finger exercises while holding the hand grip 10, the hand grip 10 will not slide relative to the hand due to the limiting effect of the five rings 24, ensuring the fixed position of the elastic protrusion 22 and the finger.

[0049] In another preferred embodiment, the handheld part 10 is a hollow cylinder, and the handheld part 10 is composed of five columnar sub-segments corresponding to the five fingers. Adjacent sub-segments are nested and are telescopic and fixed by a fastening structure (such as bolt locking or other existing fixing methods), so that the axial distance between the two elastic protrusions 22 can be adjusted to meet different exercise needs. For example, the distance between the elastic protrusions 22 can be increased, and correspondingly, the distance between the fingers corresponding to the elastic protrusions 22 of the user increases, so as to perform gripping exercises when the fingers are spread open.

[0050] Example 2

[0051] The structural principle of this embodiment is basically the same as that of Embodiment 1. The difference is that in this embodiment, the gasket 32 ​​is not provided; instead, other means are used to increase the fastening effect of the stud 31. For example... Figure 7 As shown, in this embodiment, when the top of the stud 31 is fixedly connected to the bottom of the elastic protrusion 22, the upper outer wall of the stud 31 has a plurality of hooks 50 arranged circumferentially; a flexible rope 40 is fixedly connected to one end of the arc groove 11 in the length direction. The flexible rope 40 is an elastic rope or a steel wire rope. The flexible rope 40 is fixedly connected to the other end of the arc groove 11 in the length direction after at least one of the hooks 50 is engaged.

[0052] Using the aforementioned technical solution, during initial use, the flexible rope 40 is first detached from the hook 50. After moving the elastic unit 20 to a suitable position in the arc groove 11, the stud 31 is tightened to fix the base 21. At this time, the hook 50 is located above the base 21 and does not interfere. Then, the flexible rope 40 is inserted into the hook 50, preferably along the outer circumference of the stud 31. The flexible rope 40 is inserted into several hooks 50. Under the circumferential limiting effect of the flexible rope 40 on the stud 31, the circumferential rotation and loosening of the stud 31 can be prevented. When it is necessary to move the elastic unit 20 in the circumferential position, the stud 31 should be loosened, moved to the appropriate position, and then tightened. At this time, if the flexible rope 40 is an elastic rope, it can adapt to the rotation when the bolt is tightened and loosened because the elastic rope is elastic. If the flexible rope 40 is a steel wire rope, it is not elastic because the steel wire rope is not elastic. The flexible rope 40 should be disengaged from the hook 50 first, the stud 31 should be tightened, and then the flexible rope 40 should be inserted into the hook 50.
