DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 In the present embodiment, a hand exerciser includes a shell 1 and a straight rod 4. The upper and lower right sides of the shell 1 are slidably engaged with the outer walls of the straight rod 4 respectively. The straight rod 4 slides left and right through the circular opening on the right side of the shell 1 under force. The right sides of the two straight rods 4 are connected with a control structure 2. The outer walls of the two straight rods 4 are respectively fixed with second circular rings 7. The right side of the second circular ring 7 is tightly pressed against the right side of the inner wall of the shell 1. The inner wall of the shell 1 is connected with a supporting structure 3. The outer wall of the supporting structure 3 is connected with the inner wall of the straight rod 4. A slide groove 8 is processed on the upper part of the outer wall of the supporting structure 3. The left side of the shell 1 is fixed with a second protective pad 6, and the second protective pad 6 is made of rubber. The right side of the front of the shell 1 is fixed with a glass plate 5. The glass plate 5 facilitates the viewing of the compression of the spring 303 inside the shell 1.

[0023] The control structure 2 includes a vertical plate 201 and a first pad 202. The left side of the vertical plate 201 is fixedly connected to the right side of the straight rod 4, and the right side of the vertical plate 201 is fixedly connected to the inner wall of the first pad 202. The first pad 202 is made of rubber. A cloth belt 203 is fixedly connected to the bottom of the right side of the vertical plate 201. The cloth belt 203 is made of Tencel fiber, which is a polymer fabric with good skin-friendliness. A first Velcro 204 is fixedly connected to the upper right side of the cloth belt 203. A second Velcro 205 is fixedly connected to the top right side of the cloth belt 203. A curved rod 206 is fixedly connected to the top right side of the vertical plate 201.

[0024] By controlling the thumb position in the structure 2 to be located outside the second protection pad 6, the other four fingers are then fitted with the first protection pad 202, and then the cloth belt 203 is pulled upward so that the cloth belt 203 wraps the fingers, and at the same time, the outer wall of the cloth belt 203 passes through the curved rod 206, and then the part of the cloth belt 203 that passes through the curved plate 206 is turned downward, and at the same time, the cloth belt 203 is tightened so that the second Velcro 205 and the first Velcro 204 are bonded to complete the fixation of the fingers, completing the gripping operation of the hand and the hand exerciser, changing the original form of the finger insert ring, eliminating the danger of using the hand exerciser, and meeting the use of multiple people.

[0025] The supporting structure 3 includes a column 301 and a cross bar 302. The upper and lower sides of the column 301 are respectively slidably engaged with the upper and lower sides of the inner wall of the shell 1. The column 301 slides left and right through the inner wall of the shell 1 under force. The upper and lower right sides of the column 301 are respectively fixedly connected to the left side of the cross bar 302. The outer wall of the cross bar 302 is sleeved with a spring 303. The left side of the spring 303 is fixedly connected to the right side of the column 301. The right side of the spring 303 is fixedly connected to a first ring 304. After the first ring 304 is forced to move to the left, it rebounds by the elastic force of the spring 303. The inner wall of the first ring 304 is fixedly connected to the left side of the outer wall of the straight rod 4. The right side of the outer wall of the cross bar 302 is slidably engaged with the inner wall of the straight rod 4. The straight rod 4 slides left and right on the outer wall of the cross bar 302 under force.

[0026] Working principle:

[0027] How to hold the hand exerciser:

[0028] First, wrap the palm of the hand behind the shell 1 so that the thumb is located outside the second pad 6, and then the other four fingers are fitted with the first pad 202. Then, pull the cloth belt 203 upward so that the cloth belt 203 wraps the fingers, and at the same time, pass the curved rod 206 over the outer wall of the cloth belt 203. Then, turn the part of the cloth belt 203 that passes through the curved plate 206 downward, and at the same time, tighten the cloth belt 203 so that the second Velcro 205 and the first Velcro 204 are bonded to complete the fixation of the fingers, thereby completing the gripping operation of the hand and the hand exerciser.

[0029] Hand Exerciser Hand Training:

[0030] The right finger of the first pad 202 applies force to the left side, thereby moving the vertical plate 201 to the left. The moving vertical plate 201 pushes the straight rod 4 to the left, and then cooperates with the first ring 304 to squeeze the spring 303. The spring 303 has a rebound force, which will cause the first ring 304 to move the straight rod 4 to the right, and form a holding force with the force generated by the fingers, thereby achieving hand exercise.

[0031] Embodiment 2:

[0032] See also Figure 1-6 : In this embodiment, a hand exerciser also includes a slider 9, a screw 10 and a handle 11. The two ends of the outer wall of the slider 9 are respectively slidably engaged with the inner wall of the slide groove 8, the top of the slider 9 is rotatably connected to the bottom of the outer wall of the screw 10, the outer wall of the screw 10 is threadedly connected to the top of the outer shell 1, and the top of the screw 10 is fixedly connected to the bottom of the handle 11.

[0033] Working principle:

[0034] To adjust the spring strength of the hand exerciser:

[0035] The handle 11 rotates downward with the screw rod 10 through the top of the shell 1, and the rotating screw rod 10 moves the slider 9 downward, thereby causing the end of the slider 9 to slide downward on the inner wall of the slide groove 8. Since the upper and lower sides of the column 301 are slidably engaged with the inner wall of the shell 1, the slide groove 8 cooperates with the column 301 to move to the right when the slider 9 moves downward, squeezing the spring 303 to increase the elastic potential energy of the spring 303. The straight rod 4 can maintain its position unchanged because the right side of the second ring 7 is tightly pressed against the right side of the inner wall of the shell 1, thereby positioning the straight rod 4.

[0036] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
