Springs 18 are fixedly connected to the front and rear sides of the positioning block 17. A handle 19 is fixedly connected to the surface of the spring 18. Fan-shaped plates 20 are fixedly connected to both sides of the positioning block 17. Pull ropes 13 are fixedly connected to handles 19. A reinforcing frame 5 is fixedly connected to the surface of the support post 4.

[0021] refer to Figure 3 and Figure 4 A magnet plate 21 is fixedly connected to the surface of the insertion rod 12. The magnet plate 21 is attached to the movable column 8. The movable column 8 is made of iron. A handle 22 is fixedly connected to the surface of the magnet plate 21.

[0022] As a technical optimization of this utility model, by setting the magnet plate 21, the magnetic force between the magnet plate 21 and the movable column 8 can be used to fix the insertion rod 12, preventing the insertion rod 12 from easily coming out of the slot. The operator can pull the handle 22, thereby pulling the magnet plate 21 and the insertion rod 12, and then pulling the insertion rod 12 out of the slot.

[0023] refer to Figure 1 A cylinder 24 is fixedly connected to all four sides of the bottom of the base plate 1. A first threaded rod 25 is threadedly connected inside the cylinder 24. A support pad 26 is fixedly connected to the bottom of the first threaded rod 25.

[0024] As a technical optimization of this utility model, by setting up the cylinder 24, the first threaded rod 25 and the support pad 26, the operator can rotate the first threaded rod 25, thereby driving the support pad 26 to move up or down, thereby adjusting the height or level of the base plate 1.

[0025] refer to Figure 1A sleeve 27 is fixedly connected to the top of the base plate 1. A second threaded rod 28 is connected to the inside of the sleeve 27. A seat plate 29 is fixedly connected to the top of the second threaded rod 28.

[0026] As a technical optimization of this utility model, by setting up the sleeve 27, the second threaded rod 28 and the seat plate 29, the operator can sit on the top of the seat plate 29 to train arm strength. The operator can rotate the seat plate 29, thereby driving the second threaded rod 28 to rotate, thereby adjusting the seat plate 29 to move up or down, and thus adjusting the height of the seat plate 29.

[0027] refer to Figure 1 The surface of the fixing frame 2 is fixedly connected with a first reinforcing rod 30 and a second reinforcing rod 31 respectively. The end of the first reinforcing rod 30 away from the fixing frame 2 is fixedly connected to the bracket 14, and the end of the second reinforcing rod 31 away from the fixing frame 2 is fixedly connected to the base plate 1.

[0028] As a technical optimization of this utility model, the stability between the fixing frame 2 and the support 14 can be improved by setting the first reinforcing rod 30, and the stability of the fixing frame 2 can be improved by setting the second reinforcing rod 31.

[0029] refer to Figure 1 and Figure 2 The surface of the grip 19 is provided with anti-slip grooves. The anti-slip grooves are annular and there are several anti-slip grooves. The anti-slip grooves are evenly distributed on the surface of the grip 19. A protective cover 23 is fixedly connected to the surface of the grip 19.

[0030] As a technical optimization of this utility model, the anti-slip groove can increase the friction between the operator's hand and the handle 19, thereby improving the stability of the operator gripping the handle 19. Before training, the operator puts the protective sleeve 23 on the surface of the wrist to protect the operator's arm and prevent the handle 19 from quickly resetting, which would cause the trainee's hand to separate from the handle 19 and be hit by the handle 19, thus improving the protective effect of the device.

[0031] The working principle and usage process of this utility model are as follows: During use, the operator can insert the insertion rod 12 into the slots of different counterweight plates 6. When the insertion rod 12 is inserted into the slots on the surfaces of different counterweight plates 6, the load force on the end of the pull rope 13 away from the handle 19 is the sum of the mass of the movable column 8, the mass of the movable plate 10, the mass of the support frame 11, the mass of the counterweight plate 6 into which the insertion rod 12 is inserted and the mass of all counterweight plates 6 above it, the mass of the insertion rod 12, the mass of the magnet plate 21, and the mass of the handle 22. By inserting the insertion rod 12 into slots at different heights... Inside the groove, the resistance when the operator bends the handle 19 is adjusted. Under the action of the fan-shaped plate 20, the handle 19 can only move downward in an arc, thus limiting the direction of movement of the handle 19 to avoid injury to the operator and improve the protective effect of the device. When the handle 19 moves, it will drive the pull rope 13 to move, and then through the guiding action of the guide roller 15, it will drive the support frame 11, the movable plate 10, the movable column 8 and the counterweight plate 6 to move upward. When the operator bends the handle 19, he / she needs to overcome the elastic force of the spring 18 and the load force of the pull rope 13.
