[0022] The following will list several embodiments and cooperate with the drawings to elaborate in detail on the technical content of this creation. For the component symbols cited in the following description, the same component symbols in different drawings will be regarded as the same or similar components.

[0023] See Figure 1 and Figure 2 , Figure 1 is a front view of the hand muscle strength training device of the first embodiment of this creation; Figure 2 is an exploded structural schematic diagram of the hand muscle strength training device of the first embodiment of this creation. As Figure 1 and Figure 2 shown, the hand muscle strength training device 100 of the first embodiment of this creation includes an inner rod 10, a first grip sleeve 20, a second grip sleeve 30, and a plurality of elastic resistance components 40.

[0024] The inner rod 10 is a long cylinder, having a first major axis direction T along the length direction of the inner rod 10, and includes a right rod portion 11 and a left rod portion 12. The first grip sleeve 20 and the second grip sleeve 30 are respectively sleeved from the left and right sides of the inner rod 10 onto the right rod portion 11 and the left rod portion 12 of the inner rod 10. Also see Figure 3 , which is a cross-sectional schematic diagram of the hand muscle strength training device 100. As Figure 3As shown, the length of the inner rod 10 is L1, the length of the first grip sleeve 20 is L2, the length of the second grip sleeve 30 is L3, and the sum of the length L2 of the first grip sleeve 20 and the length L3 of the second grip sleeve 30 is less than the length L1 of the inner rod 10. Therefore, when the first grip sleeve 20 and the second grip sleeve 30 are respectively sleeved on the inner rod 10, there is a distance D1 between the open end 20A of the first grip sleeve 20 and the open end 30A of the second grip sleeve 30, and the first grip sleeve 20 and the second grip sleeve 30 can rotate along the first long axis direction T. In this embodiment, the inner rod 10 is made of plastic, and in other embodiments, the material of the inner rod 10 may also include metal or wood.

[0025] Refer again to Figure 2 , in this embodiment, the main body of the first grip sleeve 20 is a cylindrical sleeve, and the open end 20A of the first grip sleeve 20 has a right angle plate 21 and a plurality of first fixing members 22. The right angle plate 21 is a ring structure and is disposed on the outer edge of the open end 20A and rotates synchronously with the first grip sleeve 20. Preferably, the outer contour of the right angle plate 21 is a circle. An angle identification mark 23 is formed on the right angle plate 21. The plurality of first fixing members 22 are disposed on the outer edge of the open end 20A of the first grip sleeve 20 in a manner surrounding the open end 20A. In this embodiment, the plurality of first fixing members 22 are a plurality of hook portions 22 disposed on the right angle plate 21. As Figure 2 shown, eight hook portions 22 protruding from the outer edge of the right angle plate 21 are provided on the right angle plate 21, and the eight hook portions 22 are equidistantly distributed on the right angle plate 21, that is, every two adjacent hook portions 22 are disposed on the right angle plate 21 at the same angle of 45 degrees. In other embodiments, the plurality of first fixing members 22 may also be hook portions of other quantities, such as four or six; or, the plurality of first fixing members 22 are, for example, fixing buckles, etc., and the present creation is not limited thereto.

[0026] In this embodiment, the second grip sleeve 30 has the same structure as the first grip sleeve 20. The main body of the second grip sleeve 30 is a cylindrical sleeve. The open end 30A of the second grip sleeve 30 has a left angle plate 31 and a plurality of second fixing members 32. Preferably, the outer contour of the left angle plate 31 is a circle. Angle recognition marks 33 are formed on the left angle plate 31. The plurality of second fixing members 32 are arranged on the outer edge of the open end 30A of the second grip sleeve 30 in a manner surrounding the open end 30A. Among them, the first fixing member 22 and the second fixing member 32 are arranged in pairs on the first grip sleeve 20 and the second grip sleeve 30 respectively. In this embodiment, the first grip sleeve 20 and the second grip sleeve 30 are made of plastic, and the plastic includes low-temperature thermoplastic material or high-temperature thermoplastic material; in other embodiments, the materials of the first grip sleeve 20 and the second grip sleeve 30 may also include metals, woods, etc. Further explanation, although in this embodiment, the first grip sleeve 20 and the second grip sleeve 30 have the shape of a cylindrical sleeve, however, in other embodiments, the first grip sleeve 20 and the second grip sleeve 30 may also include the shape of an auxiliary glove, so that users with finger injuries can also easily operate the hand muscle training device of this creation by using the auxiliary glove.

[0027] A plurality of elastic resistance components 40 are respectively installed on the corresponding first fixing member 22 and second fixing member 32 on the first grip sleeve 20 and the second grip sleeve 30. Among them, each elastic resistance component 40 has an original length before stretching, and the original length of each elastic resistance component 40 is less than the distance D1 between the open end 20A of the first grip sleeve 20 and the open end 30A of the second grip sleeve 30. In this embodiment, the elastic resistance component 40 is a rubber band; the first fixing member 22 and the second fixing member 32 are hook parts. The installation method is to stretch the elastic resistance component 40 and then put the two ends of the elastic resistance component 40 on the first fixing member 22 and the second fixing member 32 (hook parts) respectively. After being stretched, the elastic resistance component 40 will generate elastic tension, and this elastic tension can fix the first grip sleeve 20 and the second grip sleeve 30 in relative positions. Therefore, when the first grip sleeve 20 and the second grip sleeve 30 of the hand muscle training device 100 rotate relatively under an external force, for example, when the first grip sleeve 20 rotates clockwise along the first long axis direction T and the second grip sleeve 30 rotates counterclockwise along the first long axis direction T, the elastic resistance component 40 (rubber band) will generate resistance to prevent the relative rotation between the first grip sleeve 20 and the second grip sleeve 30.

[0028] Furthermore, the right angle scale 21 of the first grip sleeve 20 and the left angle scale 31 of the second grip sleeve 30 both include angle recognition marks. In this embodiment, the angle recognition marks are a plurality of graduations, and these graduations are horizontal bar marks evenly distributed on the outer ring surface of the right angle scale 21. Further, the angle recognition marks further include angle numbers, such as 0, 45, 90, 135, etc., which respectively represent 0 degrees, 45 degrees, 90 degrees, and 135 degrees. In this embodiment, the angle numbers are respectively arranged on a plurality of first fixing members 22 and a plurality of second fixing members 32. Among them, preferably, in the digital arrangement order, the plurality of angle numbers are arranged symmetrically up and down with the "0" degree as the center on the first fixing member 22 or the second fixing member 32. For example, "135, 90, 45, 0, 45, 90, 135", and the "0" degree is symmetrically arranged with the "180" degree. In this way, no matter in which direction (clockwise or counterclockwise) the user rotates the hand muscle training device 100, the angle difference can be read out from the angle numbers arranged in the above-mentioned manner.

[0029] As described above, the right angle scale 21 of the first grip sleeve 20 and the left angle scale 31 of the second grip sleeve 30 are arranged corresponding to each other. Therefore, when the first grip sleeve 20 and the second grip sleeve 30 are subjected to an external force and relatively rotate on the inner rod 10, the user applying the external force can obtain the information of the force application rotation degree through the angle difference generated by the angle recognition marks 23 of the right angle scale 21 and the angle recognition marks 33 of the left angle scale 31 due to different relative positions. As Figure 1 shown, when the hand muscle training device 100 is in the unused state, the first grip sleeve 20 and the second grip sleeve 30 are correspondingly arranged on the inner rod 10, and the angle recognition marks 23 on the right angle scale 21 and the angle recognition marks 33 on the left angle scale 31 correspond to each other. That is, the "0" degree of the right angle scale 21 corresponds to the "0" degree of the left angle scale 31, and the "45" degree of the right angle scale 21 corresponds to the "45" degree of the left angle scale 31, etc. Please also refer to Figure 4 , which is a schematic diagram of the state where the hand muscle training device 100 of the present creation is relatively rotated by an external force. As Figure 4As shown, when the user applies force to rotate the first grip sleeve 20 and the second grip sleeve 30, that is, when the "45" degrees of the right angle dial 21 corresponds to the "0" degrees of the left angle dial 31, the user can visually observe the degree of force applied according to the difference between the two, and know that the hand muscle training device 100 can generate a 45-degree rotation. Further, when the angle difference is higher, for example, when the "90" degrees of the right angle dial 21 corresponds to the "0" degrees of the left angle dial 31, the user can perceive that the hand force is increased to rotate 90 degrees. That is, when using the hand muscle training device 100, the user can obtain real-time visual feedback through the angle difference presented when the right angle dial 21 and the left angle dial 31 rotate, and use the angle difference to evaluate the size of their own hand muscle strength, and obtain a sense of achievement through using the hand muscle training device 100.

[0030] Furthermore, the plurality of elastic resistance components 40 may include elastic resistance components 40 with different resistance magnitudes. In this embodiment, the plurality of elastic resistance components 40 includes a plurality of rubber bands with different widths. Since in this embodiment, the plurality of rubber bands are detachably installed on the first fixing member 22 of the first grip sleeve 20 and the second fixing member 32 of the second grip sleeve 30, therefore, depending on the actual usage situation, the user can replace the rubber bands with different strengths. When the user's strength is small, the elastic resistance component 40 can be replaced with a set of thinner rubber bands to reduce the resistance to rotating the first grip sleeve 20 and the second grip sleeve 30; when the user's strength is large, the elastic resistance component 40 can be replaced with a set of thicker rubber bands to increase the resistance to rotating the first grip sleeve 20 and the second grip sleeve 30. The hand muscle training device 100 of the present creation can be more widely applicable to users of different ages and needs by configuring elastic resistance components 40 with several different resistance magnitudes, and greatly improves the practicality of the hand training device.

[0031] Although in this embodiment, the elastic resistance component 40 is a rubber band, however, the elastic resistance component 40 can also be other components with elastic restoring force, such as elastic bands or springs, etc., and the present creation is not limited thereto. The material of the elastic resistance component 40 can include plastics, silica gels or rubbers, etc.; when the elastic resistance component 40 is a spring, the material of the elastic resistance component 40 can further include metals.

[0032] In the foregoing embodiment, the angle numbers of the angle identification marks 23 and 33 of the right angle dial 21 and the left angle dial 31 are located on the first fixing member 22 and the second fixing member 32. However, in other embodiments, the angle numbers can also be set on the outer ring surfaces of the right angle dial 21 and the left angle dial 31, that is, set together with the scale marks, and the present creation is not limited thereto.

[0033] In another embodiment, the angle identification marks 23 and 33 on the right angle dial 21 and the left angle dial 31 may also separately include angle numbers, such as 0, 45, 90, 135, etc., and the angle numbers are set on the marks of the first fixing member 22 and the second fixing member 32. The present creation is not limited thereto.

[0034] See Figure 5 , which is a front view of the hand muscle strength training device 200 according to the second embodiment of the present creation. The hand muscle strength training device 200 in this embodiment has substantially the same structure as the hand muscle strength training device 100 in the first embodiment. The main difference is that the second grip sleeve 230 of the hand muscle strength training device 200 in this embodiment is a long rectangular sleeve, and the side wall surface 231 of the second grip sleeve 230 is composed of four planes. That is, the side wall surface 231 of the second grip sleeve 230 is a plane. Further, in the second embodiment, the weight of the second grip sleeve 230 is greater than that of the first grip sleeve 220. Therefore, in actual use, the second grip sleeve 230 of the hand muscle strength training device 200 can be placed on the desktop. By the weight of the second grip sleeve 230 itself, one end (the second grip sleeve 230) of the hand muscle strength training device 200 is fixed, and the user can rotate the first grip sleeve 220 at the other end with one hand to perform a single-handed hand muscle strength training exercise.

[0035] See Figure 6 , which is a front view of the hand muscle strength training device 300 according to the third embodiment of the present creation. The hand muscle strength training device 300 in this embodiment has substantially the same structure as the hand muscle strength training device 100 in the first embodiment. The main difference is that the side wall surfaces of the first grip sleeve 320 and the second grip sleeve 330 of the hand muscle strength training device 300 in this embodiment further include anti-slip portions 325 and 335. The anti-slip portions 325 and 335 include, for example, dot structures or stripe structures protruding from the side wall surfaces of the first grip sleeve 320 and the second grip sleeve 330, which can be used to increase the friction between the user's hand and the first grip sleeve 320 and the second grip sleeve 330.

[0036] Although the present creation lists several embodiments for illustration, these embodiments are not intended to limit the scope of the present creation. For those with ordinary knowledge in the technical field to which the present creation belongs, without departing from the spirit and scope of the present creation, various changes can still be made with reference to the content of the embodiments disclosed in the present creation. Therefore, the present creation is defined by the following scope of patent application, and any changes made within the scope of the patent application or its equivalent scope should still fall within the scope of the patent application of the present creation.
