Description

Technical Field

[0001] This invention relates to the field of grip strength measurement and training technology, and in particular to an integrated grip strength measurement and training device. Background Technology

[0002] Grip strength is a core indicator for assessing upper limb muscle strength, rehabilitation progress, and physical fitness. However, the industry has long suffered from pain points in its measurement and training devices, including functional gaps, data gaps, and ambiguous feedback. Existing products fall into two categories: one is grip strength measurement products, represented by mechanical and electronic grip strength meters, which can only capture single peak grip strength and cannot simultaneously record force changes during continuous training. Furthermore, their data recording capabilities are weak, and their applicability is limited. The other category is grip strength training products, represented by spring-loaded grip strengtheners and silicone grip rings, which can only provide resistance but cannot quantify the magnitude of each force exertion or visually represent fatigue trends during training. Additionally, resistance adjustment and data recording are disconnected. Neither type of product can meet users' core needs for "scientific training and quantitative improvement," nor can they achieve integrated "measurement-training-recording-feedback" functionality. The market urgently needs a grip strength device with a purely mechanical structure that integrates measurement and training functions and can visually present fatigue curves to address the technical bottlenecks of existing products, such as aimless training, data gaps, and cumbersome operation.

[0003] A grip strength rehabilitation training and measuring device, disclosed in CN111001133A, allows for rehabilitation training of larger hand sizes when placed within an extension sleeve. The user grips the grip plate corresponding to the extension sleeve, presses the handle according to hand size, and the handle drives a locking pin downwards. A return spring controls the downward position of the locking pin, causing its head to contact the head of a first limiting spring, which then contracts inwards. This allows the telescopic rod to move within the fixed rod, causing the buffer spring to contract or extend, which in turn causes the grip plate to change its diameter to fit the hand size. After adjustment to a suitable hand size, releasing the handle lifts the locking pin, and the return spring controls its reset. The head of the locking pin disengages from the head of a second limiting spring, causing the second limiting spring to extend outwards, thus fixing the telescopic rod within the fixed rod. The operator grips the grip plate, and pressure is transmitted through the buffer spring, telescopic rod, and support spring to the sensor for measurement. Summary of the Invention

[0004] To address the aforementioned problems, this invention aims to provide an integrated device for both grip strength measurement and training. The supporting shell is a closed casing, with multiple display tubes arranged linearly and fixedly connected inside. Multiple indicator rods are movably disposed within the display tubes, which are pre-filled with colored display liquid. The display tubes are connected to the indicator rods, and the colored display liquid is squeezed out as the indicator rods move within the display tubes, thus recording the grip strength measurement results. A linkage component is installed on the grip strength training mechanism, connecting the training mechanism and the recording and display mechanism. During grip strength training, the trainee moves the linkage component, causing the multiple indicator rods in the recording and display mechanism to shift sequentially within the display tubes. The recording and display mechanism records the trainee's grip strength each time and continuously displays it on the multiple display tubes, forming a force change curve on the multiple display tubes, reflecting the changes in finger fatigue during grip strength training.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An integrated grip strength measurement and training device includes a supporting shell, inside which a grip strength training mechanism and a recording and display mechanism are installed. The device also includes: A linkage component, connected to the grip strength training mechanism and cooperating with the recording and display mechanism, records and displays changes in grip strength during training; the linkage component includes: A horizontal rail is connected to the top of the grip strength training mechanism. As the grip strength training mechanism moves up and down repeatedly, a pulley system is installed inside, and a transmission rope is installed on the pulley system. The pressure plate moves through the horizontal rail and is connected to the transmission rope. As the grip strength training mechanism moves up and down and left and right repeatedly, it works in conjunction with the recording and display mechanism to record and display the changes in grip strength during training.

[0006] The recording and display mechanism includes: Multiple display tubes are located inside the supporting shell to display changes in the trainee's grip strength; Multiple indicator rods are movably installed inside their respective display tubes, with one end penetrating the outside of the supporting shell. When the pressure plate moves left and right, it squeezes the corresponding indicator rod, recording and displaying the changes in grip strength during training.

[0007] The linkage component also includes: The transmission gear set is located at one end of the pulley set and meshes with the toothed plate, which is connected inside the support housing. The reset motor is located inside the support housing, and its output end is connected to the other end of the pulley block to drive the pulley block to rotate.

[0008] The transmission gear set includes: The gear meshes with the gear plate, and a gear groove is provided at the center position; The engaging wheel is unidirectionally rotatable within the gear groove, and has multiple engaging teeth elastically connected to its circumference. All of the engaging teeth engage with the inner wall of the gear groove, and a drive shaft is connected to the center of the engaging wheel. Two spiral bevel gears mesh with each other. One spiral bevel gear is connected to the corresponding pulley block, and the other spiral bevel gear is connected to the drive shaft.

[0009] The grip strength training mechanism includes: The finger base is movably mounted on the supporting shell. Two reset supports are fixed inside the support housing and connected to one side of the finger seat to support the reset of the finger seat; Two negative pistons are fixed inside the support housing and connected to the other side of the finger seat via piston rods to increase resistance to the finger seat. An adjustment component, fixed inside the support housing and connected to the two negative pistons, is used to adjust the resistance of the finger seat.

[0010] The adjustment component includes: An adjusting piston cylinder is located inside a support housing and contains liquid. It is connected to the two negative pistons via a connecting pipe. An adjusting piston rod is provided with a horizontal plate, which is connected to the adjusting piston rod by a spring.

[0011] One end of the horizontal plate is connected to an adjusting screw, and the other end is slidably connected to a fixed platform, which is connected inside the supporting shell.

[0012] A reset lever is slidably disposed on the supporting housing, and the reset lever is used to push the indicator rod to reset.

[0013] An observation window is provided on the supporting shell, and a numerical label is provided on one side of the observation window.

[0014] The beneficial effects of this invention are: compared with the prior art, the improvement of this invention lies in that... 1. This invention connects the grip strength training mechanism and the recording and display mechanism through a linkage component. During the grip strength training process, the trainee will drive the linkage component to move, which in turn will cause multiple indicator rods in the recording and display mechanism to move sequentially in multiple display tubes. The recording and display mechanism can record the trainee's grip strength each time and display it continuously on multiple display tubes, so that the trainee's training data forms a force change curve on multiple display tubes, reflecting the trainee's physical strength changes during the grip strength training process.

[0015] 2. The linkage component of this invention, together with the display tube and the indicator rod, records and displays the changes in the finger strength fatigue curve during each round of training for the trainee, and adjusts the negative pressure of the device with the adjusting screw to make it suitable for trainees with different strengths, making the trainee's grip strength training more scientific and reasonable.

[0016] 3. This invention uses a horizontal rail that moves synchronously under the drive of the grip strength training mechanism to move the pressure plate horizontally along the horizontal rail. During this process, the gear moves up and down along the toothed plate once, and the pressure plate moves horizontally on the horizontal rail by the distance between the two indicator rods. In this way, each time the trainee pulls the grip strength training mechanism, the linkage component will cause the display tube to record and display the data once in conjunction with the indicator rod, overcoming the problem that traditional grip strength training devices cannot synchronously record changes in force during continuous training.

[0017] 4. When the horizontal plate is at the top of the thread on the adjusting screw, the load of this device is at its maximum value. When the adjusting screw is rotated, the horizontal plate will be displaced under the action of the thread and the fixed platform. The horizontal plate will apply elastic potential energy to the spring. The elastic potential energy will assist the trainee in pulling the piston rods of the two load-bearing pistons. When the indicator mark at the operating end of the adjusting screw is aligned with the numerical mark on the support shell, it indicates the specific value of the reduced force. The indicator mark at the operating end of the adjusting screw, in conjunction with the numerical mark on the support shell, can help the trainee adjust the training intensity and quantify the magnitude of each force exerted by the trainee.

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] See attached document Figure 1-18The integrated grip strength measurement and training device shown includes a supporting shell 1. Inside the supporting shell 1 are a grip strength training mechanism and a recording and display mechanism. The recording and display mechanism includes multiple display tubes 2, multiple indicator rods 3, and a linkage component. The multiple display tubes 2 are all located inside the supporting shell 1 and are used to display changes in the trainee's grip strength. The multiple indicator rods 3 are movably mounted inside the multiple display tubes 2, with one end penetrating the outside of the supporting shell 1, and are used to cooperate with the display tubes 2 to record the trainee's grip strength value each time. The linkage component is located on the grip strength training mechanism and is used to link the grip strength training mechanism and the recording and display mechanism.

[0039] Specifically, the supporting shell 1 is a closed casing, and multiple display tubes 2 are arranged in a straight line and fixedly connected inside the supporting shell 1. Multiple indicator rods 3 are respectively movably installed inside the multiple display tubes 2. The display tubes 2 are pre-filled with colored display liquid, and the display tubes 2 are sleeved with the indicator rods 3. A piston is fixedly installed at one end of the indicator rod 3 that is sleeved with the display tube 2. Correspondingly, a liquid storage tube is fixedly installed and connected at the end of each display tube 3 away from the corresponding indicator rod 3. In this way, when the indicator rod 3 slides into the display tube 2, the colored display liquid is squeezed out of the display tube 2 and enters the liquid storage tube under the squeezing action of the indicator rod 3, so as to realize the recording of the grip strength measurement results. The linkage component is set on the grip strength training mechanism. The grip strength training mechanism and the indicator rod 3 are linked through the linkage component. During the training process of the trainee gripping the grip strength training mechanism, the linkage component drives the indicator rod 3 to move in the display tube 2, so that the recording and display mechanism can record the trainee's grip strength each time and continuously display it on multiple display tubes. This makes the trainee's training data form a force change curve on multiple display tubes, reflecting the change of finger fatigue curve of the trainee during the grip strength training process.

[0040] In some embodiments, the linkage assembly includes a horizontal rail 4, a pressure plate 7, a transmission gear set, and a reset motor 9. The horizontal rail 4 is a rectangular plate structure with an opening, and its outer surface is fixedly connected to the top of the grip strength training mechanism. A pulley system 5 is installed inside the horizontal rail 4, and a transmission rope 6 is installed on the pulley system 5. The transmission rope 6 has a ring structure. The pulley system 5 includes two pulleys, both located inside the opening of the horizontal rail 4, and each pulley is rotatably connected to the inner wall of the opening. The transmission rope 6 is sleeved on these two pulleys and is used to drive the pressure plate 7 to move left and right within the opening of the horizontal rail 4. Specifically, a friction protrusion is fixedly installed on the side of each pulley, and correspondingly, a friction groove is fixedly installed on the transmission rope 6 to match the friction protrusion. Through the cooperation of the friction protrusion and the friction groove, friction is generated between the pulley and the transmission rope 6 when the pulley rotates. Under the action of the friction between the pulley system 5 and the transmission rope 6, the pulley system 5 drives the transmission rope 6 to rotate. The pressure plate 7 is movably disposed in the opening of the horizontal rail 4, and the bottom of the pressure plate 7 is fixedly connected to the transmission rope 6. In this way, as the transmission rope 6 rotates, the pressure plate 7 moves synchronously with the transmission rope 6. The pressure plate 7 is used to push the indicator rod 3 to slide in the corresponding display tube 2. A mounting base is fixedly installed on the outer surface of the horizontal rail 4. The reset motor 9 is fixedly installed inside the mounting base, and the output end of the reset motor 9 passes through the opening of the horizontal rail 4 and is fixedly connected to the center of one of the pulleys in the pulley group 5. The reset motor 9 is used to drive the pressure plate 7 to reset through the pulley group 5 and the transmission rope 6 so that the user can perform grip strength measurement and training next time. When the reset motor 9 is not powered, the output shaft of the reset motor 9 rotates freely. It should be noted that the reset motor 9 provided in this embodiment of the invention is prior art, and this embodiment of the invention does not improve it.

[0041] The transmission gear set is located at the end of the horizontal rail 4 away from the reset motor 9 and is located on the outside of the horizontal rail 4. It meshes with the toothed plate 8 fixedly installed on the inner side wall of the support housing 1. The upper end of the transmission gear set passes into the opening of the horizontal rail 4 and is fixedly connected to one of the pulleys of the pulley set 5. Specifically, the transmission gear set includes a gear 10, a locking wheel 12, and two spiral bevel gears 15. The gear 10 meshes with a gear plate 8 and has a gear groove 11 at its center. The locking wheel 12 is connected inside the gear groove 11 and has multiple locking teeth 13 elastically connected to its periphery. All locking teeth 13 engage with locking slots on the inner wall of the gear groove 11. A transmission shaft 14 is connected to the center of the locking wheel 12. The two spiral bevel gears 15 mesh with each other. One is parallel to the gear 10, with one end passing through the opening of the horizontal rail 4 and connecting to the center of the corresponding pulley. The other end is located outside the horizontal rail 4 and meshes with the other spiral bevel gear 15, which is fixedly connected to the transmission shaft 14 and used to drive the gear 10 to rotate via the locking wheel 12. It should be noted that the elastic connection method between the locking teeth 13 and the locking wheel 12 is not limited in this embodiment of the invention. For example, the elastic connection method is a torsion spring connection.

[0042] When the trainee pulls the grip strength training mechanism, the horizontal rail 4 moves synchronously under the drive of the grip strength training mechanism. The horizontal rail 4 drives the gear 10 to move in the same direction through the pulley group 5. Since the gear 10 is meshed with the toothed plate 8, the gear 10 rotates clockwise along the toothed plate 8 while moving. At this time, the multiple locking teeth 13 elastically connected to the periphery of the locking wheel 12 continuously abut against the sides of each locking groove on the inner wall of the gear groove 11. Each locking tooth 13 is in a closed state. At this time, the gear groove 11 and the locking wheel 12 are rotatably connected. Therefore, while the gear 10 rotates, the locking wheel 12 in the gear groove 11 will not rotate. The horizontal rail 4 will drive the pressure plate 7 to move in the same direction so that the pressure plate 7 pushes the first indicator rod 3 into the corresponding display tube 2. At this time, the indicator rod squeezes the colored display liquid in the corresponding display tube 2 into the corresponding storage tube, completing the recording of the first grip strength result. When the trainee releases the grip strength training mechanism, the horizontal rail 4 will reset under the action of the grip strength training mechanism. During the reset process, the gear 10 will rotate counterclockwise along the toothed plate 8. The multiple locking teeth 13 elastically connected to the periphery of the locking wheel 12 are in an open state and are locked in the locking groove on the inner wall of the gear groove 11. At this time, the gear 10 and the locking wheel 12 are engaged. Therefore, while the gear 10 rotates counterclockwise, the locking wheel 12 rotates counterclockwise along with the gear 10. The locking wheel 12 rotates counterclockwise through the spiral bevel gear 15 fixedly connected to the transmission shaft 14. The spiral bevel gear 15 drives another spiral bevel gear 15 to rotate clockwise, which in turn drives the pulley fixedly connected to it to rotate clockwise. The transmission rope 6 set on the pulley block 5 also rotates clockwise. The transmission rope 6 drives the pressure plate 7 to move horizontally along the horizontal rail 4, so that the pressure plate 7 is located at one end of the next indicator bar 3, so that the user can perform a second grip strength measurement. During the above process, since the display tube 2 is in a vacuum state, even if the whole device is shaken, the indicator bar 3 will not shake in the display tube 2. During this process, the gear 10 moves back and forth along the toothed plate 8 once, and the pressure plate 7 moves horizontally on the horizontal rail 4 by the distance between the two indicator rods 3. This cycle repeats. Each time the trainee pulls the grip strength training mechanism, the linkage component will cause the display tube 2 to record and display the data once in conjunction with the corresponding indicator rod 3, thus overcoming the problem that traditional grip strength training devices cannot synchronously record changes in force during continuous training. When the trainee finishes training, the reset motor 9 is started. The reset motor 9 rotates counterclockwise through each pulley in the pulley block 5. Each pulley drives the transmission rope 6 to rotate counterclockwise. The transmission rope 6 drives the pressure plate 7, which is fixedly connected to it, to move in the opposite direction until the pressure plate 7 returns to its initial position.

[0043] In some embodiments, the grip strength training mechanism includes a finger seat 16, two reset supports 17, two negative pistons 18, and an adjustment assembly.

[0044] The finger seat 16 is located in the operating groove on the support shell 1, and two sliders are respectively provided at both ends of the finger seat 16. The two sliders are slidably connected to the inner side wall of the operating groove. In actual use, since the palm size of different people is different, the size of the operating groove on the support shell 1 can be set according to gender or different hand size so as to match and be suitable for users of different genders or different hand sizes.

[0045] Two reset supports 17 are located on both sides of the finger seat 16, and one end of each reset support 17 is fixedly connected to the inner wall of the support housing 1, and the other end is fixedly connected to the end of the finger seat 16. Specifically, the reset support 17 is a spring; the reset support 17 is used to support the finger seat 16 to reset.

[0046] Two negative pistons 18 are fixed inside the support housing 1, and the two negative pistons 18 are symmetrically located on both sides of the finger seat 16; one end of each negative piston 18 is fixedly connected to one side of the corresponding finger seat 16 through a piston rod, and the other end is fixedly connected to the adjusting piston cylinder 19 through a connecting pipe 20; wherein, the adjusting piston cylinder 19 is filled with liquid; the negative pistons 18 are used to increase the resistance of the finger seat 16; The adjustment assembly is fixed inside the support housing 1 and connected to the two negative pistons 18, used to adjust the resistance of the finger seat 16. The adjustment assembly includes an adjustment piston cylinder 19 and an adjustment piston rod 21; The adjusting piston cylinder 19 is disposed inside the support housing 1 and contains liquid. The adjusting piston cylinder 19 is connected to the two negative pistons 18 through the connecting pipe 20. The adjusting piston rod 21 is a cylindrical structure with a rectangular through hole on the side, and one end of the adjusting piston rod 21 is sleeved with the adjusting piston cylinder 19, and the other end is fixedly connected to the horizontal rail 4. A horizontal plate 22 is provided inside the opening of the adjusting piston rod 21, and a spring 23 is fixedly provided at one end of the opening of the adjusting piston rod 21 near the adjusting piston cylinder 19. One end of the spring 23 is fixedly connected to the inner wall of the opening of the adjusting piston rod 21, and the other end is fixedly connected to the center of the horizontal plate 22. One end of the horizontal plate 22 is threadedly connected to an adjusting screw 24, and the other end is slidably connected to a fixed platform 25 fixed inside the supporting housing 1. The fixed platform 25 is used to keep the horizontal plate 22 in a horizontal state, and the fixed platform 25 is connected near the toothed plate 8.

[0047] One end of the adjusting screw 24, away from the horizontal plate 22, extends out of the support housing 1 and is located on the outside of the support housing 1, so that the user can adjust the resistance of the grip strength training mechanism; correspondingly, an indicator mark is fixedly provided on the additional side of the support housing 1, and numerical markings are provided on the support housing 1 along the periphery of the operating end of the adjusting screw 24.

[0048] When the trainee performs grip strength training, their palm rests against the support shell 1, and their fingers are attached to the finger seats 16. When the trainee pulls the finger seats 16, they need to overcome the elasticity of the two reset supports 17, which in turn pulls the piston rods of the two negative pistons 18. When the piston rods of the two negative pistons 18 are pulled out of their corresponding piston cylinders, the liquid in the adjusting piston cylinder 19 is drawn into the piston cylinders of the two negative pistons 18 through the connecting pipe 20. At the same time, the adjusting piston rod 21 and the horizontal rail 4 move synchronously to achieve grip strength training. When the horizontal rail 4 moves, the pressure plate 7 inside the opening of the horizontal rail 4 moves in the same direction. The pressure plate 7 pushes the indicator rod 3 to slide in the corresponding display tube 2. The colored display liquid squeezed by the indicator rod 3 enters the corresponding reservoir tube. At this time, the amount of colored display liquid remaining in the display tube 2 is used to display and record the grip strength test results.

[0049] When the resistance of grip strength training needs to be adjusted, the trainee rotates the adjusting screw 24. The horizontal plate 22 will be displaced by the thread and the fixed platform 25. The horizontal plate 22 will apply elastic potential energy to the spring 23. The elastic potential energy will assist the trainee in pulling the piston rods of the two negative pistons 18. When the indicator mark at the operating end of the adjusting screw 24 is aligned with the numerical mark on the support shell 1, it indicates the specific value of the reduced force. The indicator mark at the operating end of the adjusting screw 24, together with the numerical mark on the support shell 1, can help the trainee adjust the training intensity and quantify the amount of force exerted by the trainee each time.

[0050] When the horizontal plate 22 is located at the end furthest from the adjusting piston cylinder 19 in the opening of the adjusting piston rod 21, the pressure exerted by the horizontal plate 22 on the spring 23 is minimal. Therefore, the spring 23 has the smallest rebound force, and the force of the spring 23 assisting the piston rod of the negative piston 18 to move is minimal. At this time, the gripping resistance of this device is at its maximum value. When the horizontal plate 22 is located at the end of the opening of the adjusting piston rod 21 that is closest to the adjusting piston cylinder 19, the horizontal plate 22 applies the maximum pressure to the spring 23. Therefore, the spring 23 has the maximum rebound force, and the spring 23 assists the piston rod of the negative piston 18 to move with the maximum force. At this time, the gripping resistance of this device is at its minimum value.

[0051] In actual use, the resistance can be divided into levels by adjusting the compression of the spring 23. Preferably, when the end of the spring 23 connected to the cross plate 22 is located at the end of the piston rod 21 closest to the piston cylinder 19, the overall resistance is at the lowest level. The specific resistance can be from 10kg to 30kg, which is suitable for beginners, people in the early stages of rehabilitation, and people who need daily relaxation. When the end of the spring 23 connected to the cross plate 22 is located in the middle position of the piston rod 21, the body resistance is at a medium level, and the specific resistance can be 30kg to 60kg, which is suitable for ordinary adults to carry out daily training and muscle strength maintenance. When the end of the spring 23 connected to the cross plate 22 is located at the end of the piston rod 21 furthest from the piston cylinder 19, the overall resistance is at its highest level, with a specific resistance of 60kg to 90kg, suitable for strength trainers and professional rehabilitation strengthening groups.

[0052] In some embodiments, a reset lever 26 is slidably disposed on the support housing 1, the reset lever 26 being used to push the indicator rod 3 to reset. An observation window 27 is provided on the support housing 1, and a numerical indicator is provided on one side of the observation window 27.

[0053] Specifically, the reset lever 26 is slidably mounted on the support housing 1. When the trainee finishes a round of training, he can manually push the reset lever 26, which will push all the indicator rods 3 to the initial position. The support housing 1 is provided with an observation window 27, the position of which corresponds to the position of the display tube 2. The trainee can observe the changes in the finger fatigue curve for each round through the observation window 27.

[0054] In this way, during the process of resetting each indicator rod 3, the end of the indicator rod 3 with the piston moves to the outside of the display tube 2, so that the colored display liquid in the reservoir tube is drawn back into the corresponding display tube 2, thereby clearing the recorded data.

[0055] In some embodiments, a display screen is also provided on the support housing 1. The display screen is used to display basic information such as the gender and age of the trainee. It should be noted that the display screen provided in the embodiments of the present invention is prior art, and the embodiments of the present invention do not improve upon it.

[0056] Specific application examples of this device: 1. The trainee's palm rests on the support shell 1, and the fingers are attached to the finger seat 16. When the finger seat 16 is pulled, the elasticity of the two reset supports 17 needs to be overcome, which in turn pulls the piston rods of the two negative pistons 18. When the piston rods of the two negative pistons 18 are pulled out of the piston cylinders of the corresponding two negative pistons 18, the liquid in the adjusting piston cylinder 19 will be drawn into the piston cylinders of the two negative pistons 18 through the connecting pipe 20, which will drive the adjusting piston rod 21 and the horizontal rail 4 to move synchronously.

[0057] 2. When the trainee pulls the grip strength training mechanism, the horizontal rail 4 moves synchronously under the drive of the grip strength training mechanism. When the gear 10 rotates clockwise along the toothed plate 8, the multiple locking teeth 13 elastically connected around the locking wheel 12 will close under the action of the locking groove inclined surface on the inner wall of the gear groove 11. The locking wheel 12 in the gear groove 11 will not rotate. The horizontal rail 4 will drive the pressure plate 7 to push the indicator rod 3, so that the indicator rod 3 will squeeze the colored display liquid in the corresponding display tube 2 into the corresponding liquid storage tube. At this time, the colored display liquid remaining in the display tube 2 is used to reflect the grip strength training result. Then, when the trainee releases the grip strength training mechanism, the spring... 23. The device returns to its natural state, thereby resetting the horizontal rail 4. At the same time, gear 10 rotates counterclockwise. Gear 10 drives pulley block 5 to rotate clockwise through spiral bevel gear 15. Pulley block 5 drives pressure plate 7 to move laterally until pressure plate 7 moves to one end of the next indicator rod 3, so that the trainee can perform the next grip strength training. This cycle repeats continuously. The linkage component, together with display tube 2 and indicator rod 3, records and displays the changes in finger strength fatigue curve during each round of training. It also works with adjusting screw 24 to adjust the negative pressure of the device to suit trainees with different strengths, making the trainee's grip strength training more scientific and reasonable.
