Description

Technical Field

[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a high pull training device. Background Technology

[0002] The high pull trainer is a strength training device used to exercise the muscles of the back, shoulders, and upper limbs.

[0003] Existing high pull training equipment includes a stand, two swing arms, and a resistance source for providing training resistance. The two swing arms are rotatably mounted on the stand. Users pull down the two swing arms to make them rotate relative to the stand, thereby performing high pull training. The resistance source provides resistance during the rotation of the two swing arms relative to the stand, achieving the training effect.

[0004] However, the fixed spacing between the two arms of the aforementioned pull-up bar machine limits the diversity of training postures and fails to meet the different training needs of users. Secondly, while some improved pull-up bar machines have added multiple pairs of fixed handles to accommodate different grip positions, these handles occupy fixed space between the arms, increasing the size of the machine, the amount of material used, and thus raising the overall manufacturing cost. Furthermore, the rigid connection between the fixed handles and the arms can easily cause discomfort or even injury to the user's wrists during training, affecting training safety and comfort. Some improved pull-up bar machines also have rotatable handles on the arms. By adjusting these handles, users can only slightly adjust the width between the two arms, failing to meet the needs of users who require a wide range of grip width adjustments to train different back muscles.

Figure 1 To be continued Figure 8 Specific embodiments are described below.

[0028] Reference Appendix Figure 1 and Figure 2This application provides a high pull training device, including a base frame 100, a stand 200, a two-swing arm assembly 300 and a resistance source assembly 400. The base frame 100 is provided with a seat cushion 900. One end of the stand 200 is provided on the base frame 100 and the other end extends away from the base frame 100. The two-swing arm assembly 300 is rotatably provided on the stand 200.

[0029] The swing arm assembly 300 further includes a fixed section 301 and a swing section 302. The two fixed sections 301 are rotatably connected to the upright 200, and one end of the two swing sections 302 is rotatably connected to the two fixed sections 301, which is used to adjust the distance between the other ends of the two swing sections 302. The resistance source assembly 400 is connected to the swing arm assembly 300 and is used to provide resistance when the swing arm assembly 300 rotates relative to the upright 200.

[0030] Specifically, the base frame 100 is mounted on a bearing plane to provide an installation reference; one end of the upright frame 200 is fixed on the base frame 100, and the other end extends away from the base frame 100; the two swing arm assemblies 300 are at least at a preset distance apart and are rotatably mounted on the end of the upright frame 200 away from the base frame 100.

[0031] The stand 200 works with the base frame 100 to provide support for the two swing arm assemblies 300, so that the two swing arm assemblies 300 and the base frame 100 are separated by a preset height to rotate freely. Furthermore, a seat cushion 900 is provided on the base frame 100 to support the user to train in a seated position, thereby meeting the user's need to pull the two swing arm assemblies 300 from below for training.

[0032] The two swing arm components 300 are spaced at least a preset distance apart. The preset distance is set according to the actual situation to adapt to the natural distance between the arms of most users, so that users can naturally exert force to pull the two swing arm components 300 without relying on others, thereby improving training efficiency.

[0033] The resistance source component 400 provides resistance in ways including but not limited to physical counterweight, hydraulic or magnetic structures, to suit different training intensities and manufacturing cost requirements.

[0034] The resistance source assembly 400 is connected to the swing arm assembly 300. The resistance source assembly 400 is used to provide resistance when the swing arm assembly 300 rotates relative to the stand 200, thereby providing greater resistance to improve training efficiency during user training.

[0035] To address the user's need for training with narrow or wide-range pull-down of the two swing arm assemblies 300, i.e., the distance between the two swing arm assemblies 300 needs to be adjusted to be greater than or less than the aforementioned preset distance; the swing arm assembly 300 of this application further includes a fixed section 301 and a swing section 302. The swing section 302 and the fixed section 301 are rotatably connected to form an adjustable structure, thereby enabling the fixed section 301 to be stably used to connect the stand 200 and / or the resistance source assembly 400, while also enabling the distance between the two swing sections 302 to be adjustable.

[0036] Reference Appendix Figure 1 and Figure 2 In some embodiments, one end of the fixed section 301 is rotatably connected to the upright 200, and the other end is connected to the resistance source assembly 400.

[0037] Specifically, one end of the fixed section 301 is rotatably connected to the upright frame 200, thereby enabling the entire swing arm assembly 300 to rotate relative to the upright frame 200, forming the main motion path during training.

[0038] The other end of the fixed segment 301 is connected to the resistance source component 400, so that the resistance provided by the resistance source component 400 is stably used for the user's training process, thereby realizing the training resistance output.

[0039] The swing segment 302 is rotatably connected to the fixed segment 301 and is relatively far away from the resistance source component 400, so that the user can grasp the swing segment 302 to drive the fixed segment 301 to rotate relative to the stand 200, and so that the resistance source component 400 provides continuous training resistance output during the rotation.

[0040] The fixed section 301 is used to achieve a stable connection between the swing arm assembly 300, the stand 200, and the resistance source assembly 400, thereby ensuring the degree of freedom of the swing section 302 and enabling the swing section 302 to be flexibly adjusted according to the user's training needs.

[0041] Reference Appendix Figure 1 and Figure 2 In some embodiments, the resistance source assembly 400 includes a first transmission rod 401, a second transmission rod 402, and counterweights. One end of the first transmission rod 401 is rotatably connected to the upright 200, and a plurality of counterweights are disposed at the other end of the first transmission rod 401 away from the upright 200 to provide resistance when the first transmission rod 401 rotates relative to the upright 200. One end of the second transmission rod 402 is rotatably connected to the fixed section 301, and the other end is rotatably disposed between the two ends of the first transmission rod 401.

[0042] Specifically, one end of the first transmission rod 401 is rotatably connected between the two ends of the upright 200, and the other end is provided with multiple replaceable or stackable counterweights.

[0043] The first transmission rod 401 is used to connect the counterweight and stabilize the relative position of the counterweight and the stand 200 during training, so that the counterweight moves around a preset arc trajectory to have good mechanical responsiveness and provide training resistance stably and quickly.

[0044] One end of the second transmission rod 402 is rotatably connected to the fixed section 301, and the other end is rotatably positioned between the two ends of the first transmission rod 401, so that the fixed section 301 is connected to the first transmission rod 401, thereby ensuring that the motion resistance on the first transmission rod 401 is stably transmitted to the fixed section 301.

[0045] When the user pulls the swing arm assembly 300, the force is transmitted to the second transmission rod 402 through the fixed section 301, which further drives the first transmission rod 401 to rotate relative to the stand 200.

[0046] When the first transmission rod 401 rotates relative to the upright frame 200, since a counterweight is provided at one end of the first transmission rod 401 to generate corresponding rotational resistance, the rotational resistance of the first transmission rod 401 can be applied in the opposite direction to the swing arm assembly 300 through the second transmission rod 402.

[0047] Users can quickly adjust the training resistance by adjusting the number of counterweights set on the first transmission rod 401.

[0048] Reference Appendix Figure 1 and Figure 2 In some other embodiments, one end of the second transmission rod 402 is rotatably connected to the fixed section 301, and the other end is rotatably disposed between the two ends of the first transmission rod 401. The second transmission rod 402 and the first transmission rod 401 are detachably connected.

[0049] Specifically, the first transmission rod 401 has multiple slots between its two ends, and the second transmission rod 402 is rotatably connected to a rotating seat. The rotating seat is inserted into any slot on the first transmission rod 401. The first transmission rod 401 is also provided with a locking member to pass through the rotating seat, so that the relative position of the rotating seat and the first transmission rod 401 is fixed.

[0050] Depending on the position of the rotating seat inserted into the first transmission rod 401, the force required for the second transmission rod 402 to pull the first transmission rod 401 varies. The closer the connection between the second transmission rod 402 and the first transmission rod 401 is to the counterweight, the smaller the force required to pull the first transmission rod 401. Users can adjust the connection position between the second transmission rod 402 and the first transmission rod 401 according to training needs.

[0051] Reference Appendix Figures 1 to 8In some embodiments, a first adjustment component 500 is disposed on the swing arm assembly 300, and the first adjustment component 500 is used to lock or release the relative rotation between the swing segment 302 and the fixed segment 301.

[0052] Specifically, the swing segment 302 and the fixed segment 301 are rotatably connected to form a variable angle structure, and the first adjustment component 500 is used to control the relative rotation between the swing segment 302 and the fixed segment 301.

[0053] When the first adjustment component 500 is in the locked state, the rotation angle of the swing section 302 relative to the fixed section 301 is locked, which makes it convenient for the user to use the swing arm component 300 for training, avoids structural loosening or training instability, and ensures safety and reliability during the training process.

[0054] When the first adjustment component 500 is in the released state, the swing segment 302 can rotate relative to the fixed segment 301, which makes it convenient for the user to adjust the distance between the two swing segments 302 according to the training needs, so as to meet the user's needs to use the narrow distance, medium distance and wide distance to pull down the two swing arm components 300 for training.

[0055] It should be noted that the reference Figure 5 The center distance refers to the distance between the two swing segments 302 being equal to the preset distance between the two fixed segments 301. At this time, the relative rotation angle between the swing segment 302 and its rotating connection fixed segment 301 is zero.

[0056] refer to Figure 3 Narrow spacing means that the distance between the two swing segments 302 is less than the preset distance between the two fixed segments 301. At this time, the two swing segments 302 rotate relative to the two fixed segments 301 in the direction of moving closer to each other.

[0057] refer to Figure 7 The width refers to the distance between the two swing segments 302 being greater than the preset distance between the two fixed segments 301. At this time, the two swing segments 302 rotate relative to the two fixed segments 301 in a direction that moves away from each other.

[0058] Reference Appendix Figures 3 to 8 In some embodiments, the first adjustment component 500 includes a first positioning plate 501 and a first positioning member 502. One end of the first positioning plate 501 is fixed on the fixed section 301, and the other end extends toward the swing section 302. A plurality of first positioning holes 5011 are provided on the first positioning plate 501. The first positioning member 502 passes through the swing section 302 and extends into or out of the first positioning holes 5011 to lock or release the relative rotation between the swing section 302 and the first positioning plate 501.

[0059] Specifically, the shape of the first positioning plate 501 includes, but is not limited to, a circle, a fan shape, a strip shape, or a stepped shape.

[0060] One end of the first positioning plate 501 is fixedly mounted on the fixed section 301, and the other end extends to the area near the swing section 302. The maximum cross section of the first positioning plate 501 at least covers the movement path of the swing section 302 relative to the fixed section 301.

[0061] The first positioning plate 501 is provided with at least three first positioning holes 5011. The at least three first positioning holes 5011 are arranged at different angles or intervals to provide multi-level adjustment functions, which at least meet the needs of users to use the narrow, medium and wide distances to pull down the two swing arm assembly 300 for training.

[0062] The first positioning component 502 includes, but is not limited to, a spring pin, a threaded bolt, or a quick-release pin.

[0063] The first positioning element 502 is inserted into the swing section 302. By inserting or extending the first positioning element 502 into or out of the first positioning hole 5011, the user can achieve precise control of the rotation angle between the swing section 302 and the fixed section 301.

[0064] Before training, the user adjusts the relative position of the swing segment 302 and the fixed segment 301, and then selects a suitable first positioning hole 5011 to insert the first positioning member 502. The relative position of the swing segment 302 and the first positioning plate 501 is fixed. Based on the fixed relative position of the first positioning plate 501 and the fixed segment 301, the relative position of the swing segment 302 and the fixed segment 301 is fixed at this time.

[0065] When the user needs to adjust the relative rotation angle between the swing segment 302 and the fixed segment, by pulling the first positioning member 502 out of the first positioning hole 5011, the swing segment 302 and the first positioning plate 501 can rotate relative to each other, and the swing segment 302 and the fixed segment 301 are released relative to each other.

[0066] Through the cooperation of the first positioning plate 501 and the first positioning component 502, multi-level adjustable control of the swing segment 302 in the swing arm assembly 300 is realized. The hole design of multiple first positioning holes 5011 enhances the accuracy and flexibility of adjustment and improves the functional adaptability of the high-tension training device.

[0067] Reference Appendix Figure 1 and Figure 2 In some embodiments, the handle 1000 is rotated to connect to the swing segment 302.

[0068] Specifically, the existing technology of setting a fixed handle on the swing arm has technical problems. Since the fixed handle is rigidly connected to the swing arm, it is easy to cause discomfort or even injury to the user's wrist during training, affecting the safety and comfort of training.

[0069] The handle 1000 of this application allows the handle 1000 to rotate relative to the swing arm assembly 300 during training by rotating the swing segment 302 in the swing arm assembly 300[4], thereby adapting to changes in the grip angle and force direction of different users.

[0070] The handle 1000 includes, but is not limited to, straight, curved, or multi-angle combination types to adapt to different training needs.

[0071] In addition, the swing arm assembly 300 is rotatably connected to the stand 200, forming the main movement path during training. Furthermore, the handle 1000 is rotatably connected to the swing arm assembly 300. During training, the handle 1000 can adaptively rotate relative to the swing arm assembly 300, avoiding the user's wrist from rotating relative to the handle 1000. This allows the user to obtain a more natural movement trajectory during training, improving operational comfort and movement coordination.

[0072] By setting the handle 1000 and the swing arm assembly 300 to rotate relative to each other, the degree of freedom of the handle 1000 is increased, so that the handle 1000 can adapt to the relative rotation of the swing arm assembly 300 and the user's grip, significantly reducing the user's wrist joint pressure and improving the continuity and comfort of training movements.

[0073] Reference Appendix Figures 1 to 8 In some embodiments, the second adjustment component 600 is disposed between the handle 1000 and the swing segment 302 and is rotatably connected to both. The second adjustment component 600 is rotatably connected to the swing segment 302 about the first rotation axis 1100, and the second adjustment component 600 is rotatably connected to the handle 1000 about the second rotation axis 1200. The first rotation axis 1100 and the second rotation axis 1200 are perpendicular to each other.

[0074] Specifically, this addresses the technical problem that existing technologies add multiple pairs of fixed handles to the two swing arms to accommodate different grip postures, but these fixed handles occupy fixed space between the two swing arms, leading to an increase in the size of the device, increased material usage, and thus higher overall manufacturing costs.

[0075] This application provides biaxial rotation capability by placing the second adjustment component 600 between the handle 1000 and the swing segment 302.

[0076] Firstly, the second adjustment component 600 is connected to the handle 1000 around the second rotation axis 1200, so that the handle 1000 can rotate horizontally relative to the second adjustment component 600 in a direction parallel to the bearing plane.

[0077] Therefore, the relative position of the handle 1000 on the corresponding swing arm assembly 300 can be flexibly adjusted by the second adjustment component 600, which can work with the second swing arm assembly 300 to meet the user's needs for reverse grip high pull training in narrow, medium and wide grip situations, or for opposite grip high pull training.

[0078] By avoiding the need for multiple fixed handles to accommodate different grip postures, the aforementioned technical problems of occupying space and increasing manufacturing costs were solved.

[0079] Secondly, the second adjustment component 600 is connected to the swing segment 302 around the first rotation axis 1100, and the first rotation axis 1100 and the second rotation axis 1200 are perpendicular to each other, so that the second adjustment component 600 can rotate and adjust relative to the swing segment 302 in a direction perpendicular to the bearing plane.

[0080] Since the first rotation axis 1100 and the second rotation axis 1200 are perpendicular to each other, the handle 1000 can be given greater freedom. During training, the user can obtain a grip posture that is more in line with the natural movement trajectory, reduce the stress on the wrist joint, and improve the smoothness of training movements.

[0081] Reference Appendix Figures 3 to 8 In some embodiments, the second adjustment assembly 600 includes a second positioning plate 601, a second positioning seat 602, and a second positioning member 603. The second positioning plate 601 is rotatably connected to the swing segment 302 around the first rotation axis 1100. The second positioning plate 601 is provided with a plurality of second positioning holes. The second positioning seat 602 is rotatably connected to the second positioning plate 601 around the second rotation axis 1200 and is fixedly connected to the handle 1000. The second positioning member 603 passes through the second positioning seat 602 and extends into or out of the second positioning hole to lock or release the relative rotation between the second positioning seat 602 and the second positioning plate 601.

[0082] Specifically, the shape of the second positioning plate 601 includes, but is not limited to, a circle, a fan shape, a strip shape, or a stepped shape.

[0083] The second positioning plate 601 rotates around the first rotating axis 1100 and is connected to the swing section 302. The second positioning plate 601 can rotate and adjust relative to the swing section 302, thereby indirectly increasing the degree of freedom of the handle 1000, reducing the force on the wrist joint, and improving the smoothness of training movements.

[0084] The second positioning seat 602 is rotatably disposed on the side of the second positioning plate 601 away from the swing section 302. The second positioning seat 602 rotates relative to the second positioning plate 601 around the second rotation axis 1200, and the second rotation axis 1200 is perpendicular to the first rotation axis 1100. That is, the second positioning seat 602 can rotate relative to the swing section 302 based on the rotational connection of the second positioning plate 601.

[0085] Since the second positioning seat 602 is fixedly connected to the handle 1000, and the second positioning plate 601 and the swing segment 302 cannot rotate relative to each other around the second rotation axis 1200, the relative position of the two handles 1000 away from the swing segment 302 also changes during the rotation of the second positioning seat 602 relative to the second positioning plate 601.

[0086] refer to Figure 5 and Figure 7 When the two handles 1000 are rotated so that their extension directions are far apart, the user can grip the two handles 1000 for reverse grip high pull training; Reference Figure 3 When the two handles 1000 are rotated so that their extension directions are close to each other, the user can grip the two handles 1000 to perform high pull training.

[0087] Based on the above-mentioned reverse grip and overhand grip, by adjusting the relative rotation angle between the swing section 302 and the fixed section 301, the user's needs for reverse grip high pull training or overhand grip high pull training can be met in narrow, medium and wide grip situations.

[0088] refer to Figure 3 The two swing segments 302 rotate relative to the two fixed segments 301 in a direction that moves closer to each other. The distance between the two swing segments 302 is less than the preset distance between the two fixed segments 301. The extension direction of the two handles 1000 rotates to move closer to each other, so that the user can grip the two handles 1000 to perform close-grip high pull training.

[0089] refer to Figure 5 The relative rotation angle between the swing segment 302 and its rotating connection fixed segment 301 is zero. The distance between the two swing segments 302 is equal to the preset distance between the two fixed segments 301. The extension directions of the two handles 1000 are rotated to move away from each other, so that the user can grip the two handles 1000 to perform reverse grip mid-range high pull training.

[0090] refer to Figure 7 The two swing segments 302 rotate relative to the two fixed segments 301 in a direction that moves away from each other. The distance between the two swing segments 302 is greater than the preset distance between the two fixed segments 301. The extension directions of the two handles 1000 are rotated to move away from each other, so that the user can grip the two handles 1000 to perform reverse grip wide-distance high pull training.

[0091] The second positioning component 603 includes, but is not limited to, a spring pin, a threaded bolt, or a quick-release pin.

[0092] The second positioning element 603 is inserted into the second positioning seat 602. The user can precisely control the rotation angle between the handle 1000 and the swing segment 302 by inserting or extending the second positioning element 603 into or out of the second positioning hole on the second positioning plate 601.

[0093] Before training, the user adjusts the relative position of the second positioning plate 601 and the second positioning seat 602, and then selects a suitable second positioning hole to insert the second positioning member 603. This fixes the relative rotation angle of the handle 1000 and the swing segment 302 around the second rotation axis 1200. Based on the rotational connection between the second positioning plate 601 and the swing segment 302, the handle 1000 can still rotate relative to the swing segment 302 around the first rotation axis 1100.

[0094] By setting up a combination structure of the second positioning plate 601, the second positioning seat 602 and the second positioning component 603, the handle 1000 not only has dual-axis rotational freedom, but also achieves multi-angle precise positioning, avoiding the need to set up multiple pairs of handles 1000 to meet the different gripping needs of users, and saving manufacturing costs.

[0095] Reference Appendix Figure 1 and Figure 2 In some embodiments, the leg pad 800 is disposed on the base frame 100 and located on one side of the seat cushion 900, and the height adjustment component 700 is disposed between the leg pad 800 and the base frame 100 for adjusting the distance between the leg pad 800 and the base frame 100.

[0096] Specifically, the leg pads 800 include, but are not limited to, cylindrical, arc-shaped, straight, or multi-segment combination structures, with the surface covered with soft materials to improve comfort.

[0097] The leg pad 800 is located on the base frame 100 and on one side of the seat 900. It is used to press the legs when the user is training while sitting on the seat 900, so as to prevent the swing arm assembly 300 from moving the user's body away from the seat 900 and the base frame 100, thereby improving the stability and power efficiency of training.

[0098] The height adjustment component 700 is located between the leg pad 800 and the base frame 100. By adjusting the height adjustment component 700, the height of the leg pad 800 relative to the base frame 100 can be adjusted to meet the needs of users of different heights or body types.

[0099] The height adjustment component 700 includes, but is not limited to, slide rail type, threaded lifting type, and pin locking type structures.

[0100] Reference Appendix Figure 2In some embodiments, the height adjustment assembly 700 includes a sleeve 701, a slide rod 702, and a third positioning member 703. The sleeve 701 is hollow inside and open at one end away from the base frame 100. One end of the slide rod 702 is slidably disposed inside the sleeve 701, and the other end is connected to the leg pad 800. The slide rod 702 is provided with a plurality of third positioning holes. The third positioning member 703 is disposed through the sleeve 701 and extends into or out of the third positioning holes to lock or release the relative sliding between the slide rod 702 and the sleeve 701.

[0101] Specifically, the sleeve 701 includes, but is not limited to, a metal round tube or rectangular tube structure. The sleeve 701 is vertically fixed on the base frame 100 and has a hollow internal structure. The open end of the sleeve 701 faces the leg pad 800.

[0102] One end of the slide rod 702 is connected to the leg pad 800, and the other end is inserted into the sleeve 701 and can slide up and down inside the sleeve 701, thereby causing the leg pad 800 to slide relative to the sleeve 701, and thus adjusting the height of the leg pad 800.

[0103] The slide bar 702 includes, but is not limited to, an arc or beveled structure to further adjust the angle of the leg pad 800 during sliding.

[0104] The outer wall of the slide bar 702 is provided with multiple third positioning holes, and the third positioning member 703 passes through the side wall of the sleeve 701. The third positioning holes are used to cooperate with the third positioning member 703 for insertion and positioning.

[0105] The third positioning component 703 includes, but is not limited to, structures such as pins, spring pins, and knob locking pins.

[0106] When adjusting the height of the leg pad 800, the user can pull the third positioning member 703 out of the third positioning hole, allowing the slide rod 702 to slide freely relative to the sleeve 701 until it reaches the target height. Then, by inserting the third positioning member 703 into the corresponding third positioning hole, the relative position of the slide rod 702 and the sleeve 701 can be locked.

[0107] With the cooperation of sleeve 701, slide bar 702 and third positioning component 703, the user can quickly and accurately adjust according to leg length or training posture. When the third positioning component 703 is used for locking, it can effectively prevent the slide bar 702 from loosening or slipping during training, thus improving the stability of use and training safety.

[0108] When adjusting the high-tension training device of this application before use, the user can pull the first positioning member 502 out of the first positioning hole 5011, so that the swing section 302 and the first positioning plate 501 can rotate relative to each other, and the swing section 302 and the fixed section 301 are released relative to each other.

[0109] After adjusting the relative position of the swing segment 302 and the fixed segment 301, the user selects a suitable first positioning hole 5011 and inserts the first positioning member 502. The relative position of the swing segment 302 and the fixed segment 301 is fixed. Based on the relative rotation angle of the swing segment 302 and the fixed segment 301, the user can perform high-tension training in a narrow, medium, or wide grip.

[0110] Based on the above, the user can pull the second positioning member 603 out of the second positioning hole, so that the second positioning plate 601 and the second positioning seat 602 can rotate relative to each other. Before training, the user can rotate and adjust the relative position of the second positioning plate 601 and the second positioning seat 602, and then select a suitable second positioning hole to insert the second positioning member 603. This fixes the relative rotation angle of the handle 1000 and the swing segment 302 around the second rotation axis 1200 in the horizontal direction. The user can then perform reverse grip high pull training or opposite grip high pull training in narrow, medium, and wide grip situations.

[0111] When using the high pull trainer, the user first sits on the seat 900 with their legs against the bottom of the leg pad 800. The user raises both hands to grasp the handles 1000 located above them. The user pulls down the handles 1000 by bending their arms, thereby causing the two swing arm assembly 300 to rotate around the stand 200 for high pull training. The resistance source assembly 400 simultaneously provides rotational resistance to the two swing arm assembly 300.

[0112] This application provides a high pull training device. By improving the structure of the swing arm assembly 300, the swing segment 302 and the fixed segment 301 are rotatably connected to form an adjustable structure, thereby allowing for a significant adjustment of the distance between the two swing segments 302. This solves the problem of limited training posture caused by the fixed distance between the two swing arms in the prior art. The second adjustment component 600 flexibly adjusts the relative position of the handle 1000 on the corresponding swing arm assembly 300, and works with the two swing arm assemblies 300 to meet the user's needs for reverse grip high pull training and anti-grip high pull training in narrow, medium, and wide grip situations. This solves the technical problem of space occupation and increased manufacturing cost caused by setting multiple fixed handles in the prior art. By setting the handle 1000 to rotatably connect to the swing arm assembly 300, the degree of freedom of the handle 1000 is improved, so that the handle 1000 can adapt to the relative rotation of the swing arm assembly 300 and the user's grip, significantly reducing the user's wrist joint pressure and improving the continuity and comfort of training movements.
