[0038] Please see Figures 1 to 8 This application provides a size-adjustable arm exerciser, which includes two connecting rods 1 and two adjustable grips 2 corresponding to the two connecting rods. Users can hold either the two connecting rods 1 or the two adjustable grips 2 with both hands for exercise and fitness training. For ease of demonstration, Figures 3 to 8 The handle 22 on one side of the arm strength trainer is hidden in the middle.

[0039] In one possible embodiment, the first ends of the two connecting rods 1 are rotatably connected to each other. The first ends of the two connecting rods 1 can be directly hinged, or they can be indirectly rotatably connected via a connector. The two connecting rods 1 can rotate towards or away from each other, allowing the user to perform arm exercises by rotating the two connecting rods 1 in opposite directions using both hands. Each adjustable grip 2 can be mounted on a corresponding connecting rod 1, and each adjustable grip 2 can be located at the second end of the corresponding connecting rod 1. The size of the arm exerciser can be adjusted by displacement relative to the corresponding connecting rod 1.

[0040] Optionally, the adjustable grip 2 includes a pressing component 21 and a grip piece 22. The pressing component 21 is elastically disposed on the grip piece 22, and the pressing component 21 can be connected to the connecting rod 1. The pressing component 21 can be a structural component that allows the user to perform a pressing operation, and the grip piece 22 can be a structure that allows the user to grip it. The user can hold the grip piece 22 to perform arm fitness training.

[0041] Optionally, the pressing component 21 is used to lock the relative position of the handle 22 and the connecting rod 1. When the pressing component 21 is pressed, the pressing component 21 releases the position lock between the handle 22 and the connecting rod 1. At this time, the user can manually move the handle 22 on the connecting rod 1, thereby adjusting the relative position between the handle 22 and the connecting rod 1 to change the size of the arm strength device.

[0042] In the embodiments of this application, the user can release the position lock between the handle 22 and the connecting rod 1 by pressing the pressing component 21, thereby adjusting the relative position between the handle 22 and the connecting rod 1 to change the size of the arm exerciser to a suitable length, ultimately allowing the user to perform exercise training by holding the handle 22. The arm exerciser of this application is adjustable in size, has a simple and lightweight structure, is easy to maintain, and is suitable for a wide range of people, meeting the fitness needs of different groups.

[0043] In one possible embodiment, the pressing component 21 includes a button 211, which can be pressed by a user to release the position lock between the grip 22 and the connecting rod 1.

[0044] Optionally, the first end of the button 211 is exposed outside the connecting rod 1 and the grip 22. The first end of the button 211 can be a pressing surface. The user can press the button 211 exposed outside the connecting rod 1 to change the connection relationship between the button 211 and the grip 22.

[0045] Optionally, the grip 22 is provided with a first hole 221, and the button 211 can be inserted into the first hole 221. The middle section of the button 211 can be inserted into the first hole 221. The first end and the second end of the button 211 are located on both sides of the first hole 221, and the second end of the button 211 can be engaged with the connecting rod 1. When the second end of the button 211 is engaged with the connecting rod 1, the relative position between the grip 22 and the connecting rod 1 is locked.

[0046] Optionally, when button 211 is pressed, button 211 can disengage from the connecting rod 1, thereby releasing the position lock between handle 22 and connecting rod 1. Thus, pressing button 211 can release the position lock between handle 22 and connecting rod 1, allowing handle 22 to slide on connecting rod 1.

[0047] In one possible embodiment, the button 211 includes a first shaft segment 212 and a second shaft segment 213, the second shaft segment 213 being located at the second end of the button 211, and the first shaft segment 212 being located between the first end and the second end of the button 211.

[0048] Optionally, the connecting rod 1 is provided with at least two second holes 11, and a connecting groove 12 is provided between each two adjacent second holes 11. Each of the at least two second holes 11 is used to engage with the second shaft segment 213, and the first shaft segment 212 can slide back and forth in the connecting groove 12.

[0049] Optionally, the size of the second hole 11 can be the same as the size of the second shaft segment 213, and the second hole 11 can also be interference-fitted with the second shaft segment 213 to prevent the second shaft segment 213 from coming out of the second hole 11 when the pressing component 21 is not pressed.

[0050] Optionally, the size of the connecting groove 12 can be the same as the size of the first shaft segment 212, and the first shaft segment 212 can also be clearance-fitted with the connecting groove 12, thereby reducing the motion resistance between the grip 22 and the connecting rod 1.

[0051] In one possible embodiment, the pressing component 21 includes a return spring 214, which may be disposed between the button component 211 and the grip component 22.

[0052] Optionally, the first end of the button 211 is elastically connected to the handle 22 via a return spring 214. The return spring 214 is used to restore the engagement state between the second shaft segment 213 and the second hole 11 after the arm strength adjustment is completed, so that the button 211 is reset and the position lock between the handle 22 and the connecting rod 1 is restored.

[0053] In one possible embodiment, the return spring 214 is in a compressed state during the adjustment of the arm strength device's size.

[0054] Optionally, when the user does not press the button 211 and the second shaft segment 213 of the button 211 is engaged with the second hole 11, the return spring 214 can be in a naturally relaxed state. When the user presses the button 211, the second shaft segment 213 of the button 211 disengages from the second hole 11, and the first shaft segment 212 of the button 211 is located in the connecting groove 12. The return spring 214 can be in a compressed state. When the first shaft segment 212 of the button 211 is displaced in the connecting groove 12 to any of the second holes 11 and the user does not press the button 211, the second shaft segment 213 of the button 211 engages with this second hole 11 under the elastic force of the return spring 214.

[0055] In one possible embodiment, the outer diameter of the second shaft segment 213 is larger than the outer diameter of the first shaft segment 212. Similarly, the inner diameter of the second hole 11 is also larger than the inner diameter of the connecting groove 12. This design is ensured by a structural design that allows the second shaft segment 213 to engage with the second hole 11 and the first shaft segment 212 to slide within the connecting groove 12.

[0056] In one possible embodiment, the connecting rod 1 is provided with four second holes 11. A connecting groove 12 is provided between each pair of adjacent second holes 11. These four second holes 11 correspond to four different adjustable lengths of the arm extension device, and the second shaft segment 213 can engage with different second holes 11 to achieve size adjustment of the arm extension device.

[0057] In one possible embodiment, the arm exerciser has at least one directional wheel 3 on its bottom side. Besides using the arm exerciser for arm strength training, users can also perform abdominal exercises by sliding the arm exerciser back and forth on the ground while supporting themselves with their hands. Currently, arm exercisers on the market often have omnidirectional wheels on their bottom side to achieve the abdominal exercise mode. However, during the sliding process of such arm exercisers, the running trajectory is unstable and easily deviates from its path, potentially injuring the user. This application replaces the omnidirectional wheels with directional wheels 3, which have higher structural stability.

[0058] In one possible embodiment, the first ends of the two connecting rods 1 are rotatably connected by a rotating connecting part 5, which can be a connecting seat structure, and at least one directional wheel 3 is provided on the bottom side of the rotating connecting part 5.

[0059] Optionally, at least one directional wheel 3 is provided on the bottom side of each of the two connecting rods 1. The at least one directional wheel 3 on the bottom side of the two connecting rods 1 can be symmetrical to each other.

[0060] In one possible embodiment, the arm strength device may include a hydraulic cylinder 4, and the arm strength device can be an arm strength device that supplies resistance to the hydraulic cylinder 4. Compared with the resistance supply methods of the prior art such as spring supply or counterweight supply, the resistance supply method of hydraulic cylinder 4 has the advantages of safety, efficiency, quietness, and portability.
