[0022] See also Figure 1-4 A handgrip strengthener for pre-training arteriovenous fistula with countable function, comprising a first handle 1, an inner wall of the first handle 1 being rotatably connected to an adjustment frame 2, and an outer side of the first handle 1 being provided with an adjustment mechanism 3;

[0023] The adjustment mechanism 3 includes a second handle 301, the outer surface of the second handle 301 is slidably connected to the inner wall of the adjustment frame 2, a push-type counter 5 is fixedly installed on the inner wall of the first handle 1, and an anti-slip pad 4 is fixedly connected to the outer surface of the first handle 1. By setting the push-type counter 5 and the anti-slip pad 4, the push-type counter 5 can squeeze and count when the two handles are in contact, and the anti-slip pad 4 can prevent the hand from slipping during squeezing.

[0024] Two extrusion plates 302 are slidably connected to the inner wall of the adjustment frame 2, and the outer surface of each extrusion plate 302 is slidably connected to the inner wall of the second handle 301. A spring 6 is provided above the adjustment frame 2, and the outer surface of the spring 6 is in contact with the inner wall of the first handle 1. By providing the spring 6, the pressure required for exercise can be provided, thereby achieving the effect of exercise.

[0025] The inner wall of each extrusion plate 302 is threadedly connected to two first threaded rods 303, and the outer surface of the spring 6 is slidably connected to the moving block 7. The outer surface of the moving block 7 is slidably connected to the inner wall of the adjustment frame 2. By setting the moving block 7, it is convenient to pull the spring 6 to adjust the pressure intensity, which is convenient for different people to use.

[0026] Both ends of each first threaded rod 303 are rotatably connected to the inner wall of the adjusting frame 2, and the outer surface of each first threaded rod 303 is fixedly connected to a worm gear 306. The inner wall of the moving block 7 is threadedly connected to a threaded wire 8, and the outer surface of the threaded wire 8 is threadedly connected to the inner wall of the spring 6. By setting the threaded wire 8, the spring 6 can be firmly fixed, and the subsequent disassembly of the spring 6 is also facilitated.

[0027] The outer surface of each worm wheel 306 is meshedly connected to a worm 305, and the outer surface of each worm 305 is rotatably connected to the inner wall of the adjusting frame 2. The inner wall of the moving block 7 is threadedly connected to a second threaded rod 9, and the outer surface of the second threaded rod 9 is rotatably connected to the inner wall of the adjusting frame 2. By setting the second threaded rod 9, the moving block 7 can be driven to move by the second threaded rod 9, thereby quickly performing pressure adjustment work.

[0028] The ends of each group of worm gears 305 that are close to each other are fixedly connected to the roller 304, and the left end of the second threaded rod 9 is fixedly connected to the rotating block 10. The outer surface of the rotating block 10 is provided with anti-slip grooves 11 arranged at equal distances. By setting the rotating block 10 and the anti-slip grooves 11, it is convenient for people to rotate the second threaded rod 9 through the rotating block 10, and the anti-slip grooves 11 can prevent hands from slipping.

[0029] The working principle of the present invention is as follows: when in use, the nurse first takes the exercise equipment to a suitable position for use, and then the nurse asks the patient to test the pressure intensity of the handgrip. When the pressure intensity of the handgrip needs to be adjusted, the nurse manually rotates the second threaded rod 9 through the rotating block 10. During the rotation, the second threaded rod 9 can drive the moving block 7 on the surface to move. When the moving block 7 moves inside the adjustment frame 2, the spring 6 can be pulled for adjustment, and the pressure intensity of the device can be changed according to the adjustment spring 6. Then the patient tests again whether the gripping distance between the first grip 1 and the second grip 301 is appropriate. When the gripping distance needs to be adjusted, the nurse manually turns the roller 304, and the roller 304 can be turned. The rotation of the roller 304 can drive the two worms 305 on the surface to rotate. Under the action of the rotation of the worm 305, the worm 305 can drive the worm wheel 306 on the surface to rotate. The rotation of the worm wheel 306 can drive the first threaded rod 303 inside to rotate. Then the rotation of the first threaded rod 303 can drive the extrusion plate 302 to move until it moves to a suitable position, and then the limiting effect on the second handle 301 can be released. After the limiting effect is released, the second handle 301 can be pushed to move and adjust. After the adjustment is completed, the extrusion plate 302 is reset to the limit. Finally, exercise is performed by squeezing the two handles. When the first handle 1 and the second handle 301 are pressed together, the push-type counter 5 can be pressed to count.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
