The arm strength exercising apparatus further includes a resistance mechanism, the two resistance arms are of tubular structures, the resistance mechanism includes a resistance member 2 and a pull rope 3, the resistance member 2 is arranged in the first resistance arm 11, and the pull rope 3 is connected between the resistance member 2 and the second resistance arm 12. The pull rope 3 may be a steel wire rope or other high-strength rope. In a closing process of the two resistance arms, the resistance member 2 can be pulled by the pull rope 3, and the resistance member 2 provides resistance for the closing of the two resistance arms to achieve an exercise effect. By arranging the resistance member 2 inside the two tubular resistance arms, the space occupied by the overall arm strength exercising apparatus can be reduced, and the space utilization can be improved. In addition, by arranging the resistance member 2 inside the resistance arms, the effect of hiding the resistance member 2 can be achieved, the influence on the exercise effect due to contact with the resistance member 2 during exercise can be avoided, and the arm strength exercising apparatus is exquisite, attractive, and light. The resistance member 2 in this embodiment is specifically an oil cylinder, a cylinder body of the oil cylinder is fixedly arranged in the first resistance arm 11, the pull rope 3 is connected to a piston rod 21 of the oil cylinder, a blocking structure 22 is arranged in the first resistance arm 11, and the cylinder body of the oil cylinder is mounted from a lower end of the first resistance arm 11 and blocked by the blocking structure 22. The blocking structure 22 can prevent the oil cylinder from being pulled by the pull rope 3 to move, thereby affecting the exercise effect. The blocking structure 22 is a pin that crosses the first resistance arm 11, and the oil cylinder includes a resistance adjustment knob 114 arranged at a rear end of the cylinder body and located outside the first resistance arm 11. The resistance can be adjusted according to the user's situation through the resistance adjustment knob 114. Alternatively, the resistance member 2 may be an air cylinder. Structures of both the oil cylinder and the air cylinder are disclosed existing technologies, and will not be described in detail here. A buffer layer is sleeved at lower ends of the two resistance arms to increase the user's grip comfort.

[0039] The adapter mechanism includes an inner adapter 41 and an outer adapter 42, the inner adapter 41 is fixedly connected to the upper end of the first resistance arm 11, the outer adapter 42 is fixedly connected to the upper end of the second resistance arm 12, the outer adapter 42 is rotatably sleeved on an outer side of the inner adapter 41, and a bearing 6 is arranged between the inner adapter 41 and the outer adapter 42 to facilitate smoother rotation between the outer adapter 42 and the inner adapter 41 and reduce friction. The outer adapter 42 is provided with a guide structure for positioning and guiding the pull rope 3, and the guide structure is an arc-shaped guide groove 421 formed on an outer circumferential surface of the outer adapter 42 to insert the pull rope 3. One end of the pull rope 3 is connected to the resistance member 2, and the other end is threaded out from an upper port of the first resistance arm 11, passes through the arc-shaped guide groove 421, and then is connected to the second resistance arm 12. In this way, when the inner adapter 41 and the outer adapter 42 rotate oppositely, the pull rope 3 can be well guided to stretch the resistance member 2. In addition, the arc-shaped guide groove 421 can facilitate mounting of the pull rope 3 and prevent the pull rope 3 from slipping.

[0040] The first resistance arm 11 is connected to the inner adapter 41 through a first connector, and the second resistance arm 12 is connected to the outer adapter 42 through a second connector. The first connector includes a first holding ring 111 with a notch and two first clamping plates 112 extending from two ends of the notch of the first holding ring 111 to two sides of the inner adapter 41, the first holding ring 111 surrounds the upper end of the first resistance arm 11, and the two first clamping plates 112 are fixedly connected to the inner adapter 41 through first fasteners 115 crossing the first clamping plates 112 and the inner adapter 41.

In this way, the first holding ring 111 and the second holding ring 121 can be stably fixed to the resistance arms. An end, connected to the second resistance arm 12, of the pull rope 3 is fixed to the fourth fastener 123. The first fasteners 115, the second fasteners 124, the third fastener 113, and the fourth fastener 123 are specifically fixing pins in this embodiment.

[0041] A first annular step 411 is formed on an outer circumferential surface of the inner adapter 41, an adapter hole 43 matched with the inner adapter 41 is formed in the outer adapter 42, a second annular step 422 opposite to the first annular step 411 is formed on an inner circumferential surface of the adapter hole 43, the bearing 6 is arranged between the inner adapter 41 and the outer adapter 42 and abuts against the first annular step 411 and the second annular step 422, a first snap spring groove 412 is formed on the outer circumferential surface of the inner adapter 41, a second snap spring groove 431 opposite to the first snap spring groove 412 is formed on an inner circumferential surface of the outer adapter 42, and a snap spring 44 is arranged in each of the two snap spring grooves. An outer ring of the bearing 6 is limited between the second annular step 422 and the snap spring 44, and an inner ring of the bearing 6 is limited between the first annular step 411 and the snap spring 44, thereby preventing the bearing 6 from detaching between the inner adapter 41 and the outer adapter 42.

[0042] The arm strength exercising apparatus further includes a circular protective shell 5 covering the adapter mechanism, the protective shell 5 is fixedly connected to the outer adapter 42, a long notch 71 avoiding the first connector is formed on an outer circumferential surface of the protective shell 5, and an arc-shaped shielding plate 7 covering the notch is arranged on the first connector. When the two resistance arms are closed, the first resistance arm 11 drives the first connector to move, and the long notch 71 can avoid the first connector, so the clamping operation of the two resistance arms is not blocked. A counter is arranged inside the protective shell 5, a control panel 51 is arranged on the protective shell 5, and a display screen 53 displaying the number of times of the counter and a control button 52 are arranged on the control panel 51.

The adapter shaft 9 is a bolt crossing the first adapter 7 and the second adapter 8, and is in threaded connection by nuts 92 after crossing. The adapter shaft 9 is sleeved with a wear-resistant sleeve, which is a shaft sleeve 91. The shaft sleeve 91 can increase the wear resistance of the first adapter 7 and the second adapter 8 and make the rotation of the two adapters smoother. The shaft sleeve 91 is arranged between the two clamping arms, a square limit portion 93 is formed on the adapter shaft 9, and a square hole 711 matched with the limit portion 93 is formed on the upper clamping arm 71. The limit portion 93 is matched with the square hole 711 to prevent the adapter shaft 9 from rotating relative to the first adapter 7, but rotating relative to the second adapter 8.

[0045] The second adapter 8 includes two outer adapter pieces 81 and two inner adapter pieces 82, the two inner adapter pieces 82 are clamped between the two outer adapter pieces 81, the two inner adapter pieces 82 are formed with arc-shaped outer circumferential surfaces for supporting the pull rope 3, and the two outer adapter pieces 81 extend beyond the arc-shaped outer circumferential surfaces, so that the two outer adapter pieces 81 and the arc-shaped outer circumferential surfaces form guide grooves 83 to facilitate production and assembly of the product, form the guide grooves 83 better, and increase the strength of the second adapter 8 to some extent. The guide grooves 83 can prevent the pull rope 3 from slipping. One end of the pull rope 3 is connected to the resistance member 2, while the other end is threaded out from the upper port of the first resistance arm 11 and passes through the guide grooves 83 before being connected to the second resistance arm 12 through a connecting ring 31. The connecting ring 31 is sleeved on a pin 125 crossing the upper end of the second resistance arm 12.
