Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

As shown in Figure 1-5, a hand exerciser includes a mounting shell 1. An inner groove 8 is provided on one side of the mounting shell 1. A mounting plate 2 is movable outside the inner groove 8, and a connecting plate 3 is fixedly mounted outside the mounting plate 2. , the connecting plate 3 is provided with multiple sets of drawing holes 4 up and down, and the inner side of the mounting plate 2 is fixedly provided with multiple sets of mounting rods 11. The outer ends of the multiple sets of mounting rods 11 are provided with hooks 12, and the outer sides of the mounting shell 1 are located on both sides of the inner groove 8 Fixed cylinders 5 are fixedly provided on both sides, and connecting rods 6 are movably plugged into the inner sides of the two groups of fixed cylinders 5. The outer ends of the connecting rods 6 move through the fixed cylinders 5 and are fixedly connected to the mounting plate 2, and there is a first movably arranged inner side of the fixed cylinder 5. Spring 7, one end of the first spring 7 is connected to the inner wall of the fixed cylinder 5, and the other end of the first spring 7 is connected to the connecting rod 6. There are multiple sets of second springs 9 movable inside the inner groove 8, and the multiple sets of second springs 9 are connected at one end. On the inner wall of the inner groove 8, and the other end of the second spring 9 is fixedly provided with a hanging ring 10 that is connected to the hook 12. The second spring 9 is provided with multiple groups, and through the quick connection effect of the hanging ring 10 and the hook 12, it is convenient to use different A number of second springs 9 are used for hand exercise, effectively improving the hand exercise effect at each stage.

Among them, a limit block is fixed on the outside of the connecting rod 6, and a limit groove for docking the limit block is provided on the inside of the fixed cylinder 5. When the mounting plate 2 is pulled for hand exercise, the connecting rod 6 can be driven to move in the fixed cylinder 5, and the connecting rod 6 can be moved through the fixed cylinder 5. The limited cooperation between the limit block and the limit groove can prevent the connecting rod 6 from being separated from the fixed cylinder 5, thus ensuring the normal use of the device.

Among them, a rubber pad 13 is provided inside the draw hole 4. When a finger is inserted into the draw hole 4, the finger comes into contact with the rubber pad 13 in the draw hole 4, thereby improving the comfort of the finger.

Among them, an installation groove 14 is provided on the other side of the installation shell 1. A threaded rod 15 is provided for rotation on the inside of the installation groove 14. Two sections of threads in opposite directions are provided on the outside of the threaded rod 15, and two sections of threads in opposite directions on the outside of the threaded rod 15 are provided. Both sets of splints 16 are set, and the two sets of splints 16 move through the installation slot 14 and extend to the outside, and the threaded rod 15 moves through the installation slot 14 and extends to the upper side. The upper end of the threaded rod 15 is located on the upper side of the installation slot 14 and is fixed with a turntable. 17. By rotating the turntable 17, the two sets of splints 16 can be driven to move simultaneously, so that the distance between the two sets of splints 16 becomes closer and closer, thereby facilitating the fixation of the device. When the turntable 17 is rotated in the opposite direction, the two sets of splints 16 can be driven. They move at the same time and the distance becomes larger and larger, making it easier to disassemble the device and making it very flexible and convenient to use.

Among them, a chute 18 for docking the splint 16 is provided on the inside of the installation groove 14. The splint 16 is limited to slide in the chute 18. The splint 16 is limited by the chute 18, so that when the threaded rod 15 rotates, the two sets of splints 16 It can move along the threaded rod 15, thereby improving the movement stability of the splint 16.

Among them, an anti-slip pad 19 is provided on the outside of the plywood 16. The anti-slip pad 19 is made of soft material. When the table body is clamped by the two sets of plywood 16, the anti-slip pad 19 contacts the upper and lower sides of the table body, thereby improving the fixation of the device. firmness to avoid slipping.

Among them, multiple sets of anti-slip blocks 20 are provided on the outside of the turntable 17. The anti-slip blocks 20 can increase the friction, thereby making it easier to rotate the turntable 17 and improving the convenience of fixing the device.

Embodiment: During use of the utility model, first fit the installation groove 14 to the desktop, and then rotate the turntable 17 to drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, the two sets of splints 16 are limited by the chute 18. The two sets of splints 16 move toward each other along the threaded rod 15 until the two sets of splints 16 are clamped on the upper and lower sides of the table body, thereby facilitating the fixation of the device. Then the patient can insert his fingers into the pull hole 4 and pass through Pulling the connecting plate 3 drives the connecting rod 6 to move outward in the fixed cylinder 5. When the connecting rod 6 moves, it stretches the first spring 7, thus completing the preliminary hand exercise. When the patient gradually recovers, the hand strength also gradually increases. When the hanging ring 10 is pulled and hooked to the hook 12, it is convenient to connect the second spring 9 to the mounting plate 2. At this time, the resistance of the mounting plate 2 increases, thereby facilitating the patient's later recovery exercise. Since the second spring 9 is provided with multiple groups, so a corresponding number of second springs 9 can be selected according to actual use requirements. The use is very flexible and convenient, and can meet different stages of hand exercise.
