[0022] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] like Figure 1-Figure 4 As shown, a grip strength tester that is easy to adjust includes a mounting frame 1, one end of the inner side of the mounting frame 1 is fixedly connected to a fixed connecting rod 2, the inner side of the mounting frame 1 is symmetrically provided with a fixed guide groove 3, one end surface of the mounting frame 1 is fixedly connected to a fixed threaded ring 4, the interior of the mounting frame 1 and the inner side of the fixed threaded ring 4 are provided with a movable adjustment mechanism 5, and the output end of the movable adjustment mechanism 5 is fixedly connected to a grip strength detection mechanism 6.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the position of the grip force detection mechanism 6 can be adjusted through the movable adjustment mechanism 5, so that the distance between the grip force detection mechanism 6 and the fixed connecting rod 2 can be quickly adjusted, and thus can be suitable for users with different hand sizes and easy to operate.

[0027] In another embodiment, Figure 3 As shown, the movable adjustment mechanism 5 includes an adjusting threaded rod 7, one end of the adjusting threaded rod 7 is fixedly connected to a rotating disk 8, the other end of the adjusting threaded rod 7 is fixedly connected to a first fixed connecting block 9, a connecting sleeve block 10 is movably sleeved on the outer surface of the first fixed connecting block 9, and a first connecting mounting plate 11 is fixedly connected to the side of the connecting sleeve block 10 away from the adjusting threaded rod 7, and a second fixed connecting block 12 is fixedly connected to the end of the first connecting mounting plate 11.

[0028] During the adjustment process, the rotating disk 8 is first rotated to drive the adjusting threaded rod 7 and the first fixed connecting block 9 to rotate, so that the adjusting threaded rod 7 can move inside the fixed threaded ring 4 and the mounting frame 1, and move the connecting sleeve block 10, the first connecting mounting plate 11 and the second fixed connecting block 12, thereby adjusting the position of the grip detection mechanism 6, which is easy to operate.

[0029] In another embodiment, Figure 3 As shown, the adjusting threaded rod 7 is connected to the fixing threaded ring 4 and the interior of the mounting frame 1 via threads.

[0030] It is convenient to adjust that when the threaded rod 7 rotates inside the mounting frame 1 and the fixed threaded ring 4, it can move stably and is easy to operate.

[0031] In another embodiment, Figure 1 and Figure 3As shown, the outer surface of the second fixed connection block 12 and the inner surface of the fixed guide groove 3 are slidably fitted with each other.

[0032] This facilitates the second fixed connection block 12 to move stably inside the fixed guide groove 3 when following the movement of the first connection mounting plate 11 , and facilitates operation.

[0033] In another embodiment, Figure 3 As shown, the end surface of the first connecting mounting plate 11 and the inner surface of the mounting frame 1 are slidably fitted to each other.

[0034] This facilitates the movement of the first connecting mounting plate 11 so that the end portion of the first connecting mounting plate 11 can move inside the mounting frame 1 , which is easy to operate.

[0035] In another embodiment, Figure 4 As shown, the grip force detection mechanism 6 includes a connecting sleeve 13, and the interior of the connecting sleeve 13 is movably connected to a movable connecting rod 14, one end of the movable connecting rod 14 is fixedly connected to a force-bearing mounting plate 15, and the other end of the movable connecting rod 14 is fixedly connected to a second connecting mounting plate 17, and a force spring 16 is fixedly connected between one side of the force-bearing mounting plate 15 and the inner end of the connecting sleeve 13.

[0036] It is convenient to pull the second connecting mounting plate 17 to drive the movable connecting rod 14 and the force-bearing mounting plate 15 to move, thereby squeezing the force-bearing spring 16. The force-bearing spring 16 can provide a reverse force to detect the gripping force, and the operation is convenient.

[0037] In another embodiment, Figure 4 As shown, a connecting pull plate 18 is fixedly connected to the side of the second connecting mounting plate 17 away from the movable connecting rod 14 , and a fixing through slot 19 is defined inside the connecting pull plate 18 .

[0038] It is convenient for users to pull the connecting pull plate 18 through the fixed through slot 19, thereby driving the second connecting mounting plate 17 to be pulled, which is more convenient.

[0039] The working principle of the utility model is as follows: during use, the rotating disk 8 is rotated, driving the adjusting threaded rod 7 and the first fixed connecting block 9 to rotate, so that the adjusting threaded rod 7 can move inside the fixed threaded ring 4 and the mounting frame 1, and the connecting sleeve block 10, the first connecting mounting plate 11 and the second fixed connecting block 12 are moved, so that the positions of the connecting sleeve 13, the movable connecting rod 14, the force mounting plate 15, the force spring 16, the second connecting mounting plate 17 and the connecting pull plate 18 can be adjusted, so that the distance between the connecting pull plate 18 and the fixed connecting rod 2 is adjusted, and then the operator can hold the fixed connecting rod 2, and at the same time extend his hand into the inner side of the fixed through groove 19, and pull the connecting pull plate 18, driving the second connecting mounting plate 17, the movable connecting rod 14 and the force mounting plate 15 to move, so that the force mounting plate 15 and the connecting sleeve 13 cooperate, causing compression of the force spring 16, thereby testing the operator's grip strength. The overall structure is simple and the operation is convenient and quick.

[0040] The above embodiments merely represent specific implementation methods of the present invention. Although the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
