[0048] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] Please refer to Figures 1 to 5. This application provides the following technical solutions:

[0050] The handle adjustment structure includes a main connector 21 and a secondary connector 22. The main connector 21 can be fixedly connected to an external structure, or the corresponding connection position of the external structure can be used as the main connector 21. The secondary connector 22 is a U-shaped frame, with its open end rotatably connected to the main connector 21. A handle connector 23 is fixedly mounted on the closed end of the secondary connector 22, through which a handle 24 is rotatably connected. A first positioning component 25 is provided between the handle connector 23 and the handle 24 to lock the position of the handle 24. A second positioning component 26 is provided between the secondary connector 22 and the main connector 21 to lock the position of the secondary connector 22.

[0051] This structure provides the handle 24 with two adjustable connection points: one is the connection between the handle 24 and the handle connector 23, and the other is the connection between the secondary connector 22 and the main connector 21. The adjustability provided by these two connection points allows for greater angle variation in the handle 24, thus meeting the needs of different users.

[0052] Based on the above implementation scheme, referring to Figure 2, the handle connector 23 has a cylindrical structure with an insertion hole inside. The handle 24 has an approximately "L"-shaped structure, including a grip portion 241 and an insertion portion 242. The grip portion 241 is for user gripping and is rod-shaped, with an outer layer covered by an elastic material pad. The insertion portion 242 includes a rod inserted into the insertion hole of the handle connector 23.

[0053] Through this structure, the cooperation between the insert rod and the socket forms a rotational connection between the handle 24 and the handle connector 23, while also satisfying the sliding connection between the two with the axial direction of the socket of the handle connector 23 as the direction of movement.

[0054] Based on the above implementation scheme, the first positioning component 25 includes a first positioning plate 251 and a first positioning pin 252. The first positioning plate 251 is a fan-shaped plate body, and is fixedly disposed on the side of the handle connector 23 facing the grip portion 241 of the handle 24. Several positioning grooves are formed on the edge of the first positioning plate 251, and the positioning grooves are notches on the first positioning plate 251. The first positioning pin 252 is fixedly disposed on the insertion portion 242 of the handle 24 near the grip portion 241. The first positioning pin 252 corresponds to the positioning groove on the first positioning plate 251, and the handle 24 can be engaged with the first positioning plate 251 through the first positioning pin 252. The insertion direction of the first positioning pin 252 and the first positioning plate 251 is parallel to the sliding direction of the insertion rod.

[0055] When the handle 24 needs to be adjusted, first pull the handle 24 to remove the first positioning pin 252 from the positioning groove of the first positioning plate 251. Then the handle 24 can rotate freely. Select a suitable angle, insert the first positioning pin 252 back into the positioning groove of the first positioning plate 251, and the angle adjustment of the handle 24 can be completed.

[0056] Based on the above implementation scheme, the length of the insert rod is greater than the length of the insertion hole of the handle connector 23. One end of the insert rod is connected to the grip portion 241, and the other end extends to the outside of the handle connector 23. The handle 24 also includes a handle limiting member 243 and a reset member 244. The handle limiting member 243 and the end of the insert rod away from the grip portion 241 are connected by bolts. The handle limiting member 243 can be sleeved on the outside of the handle connector 23, and a boss structure is provided inside the handle limiting member 243, which can abut against the end of the handle connector 23. The reset member 244 is a spring, sleeved on the outside of the insert rod, and the reset member 244 is located between the boss of the handle limiting member 243 and the handle connector 23.

[0057] When the handle 24 is pulled, the first positioning pin 252 disengages from the first positioning plate 251, and the reset member 244 is compressed. Due to the action of the handle limiting member 243, the handle 24 will not separate from the handle connecting member 23.

[0058] Based on the above implementation scheme, the second positioning component 26 includes a second positioning plate 261 and a second positioning pin 262. The second positioning plate 261 is fixedly connected to the main connecting member 21, and the second positioning plate is disposed at the end of the main connecting member 21 facing the handle connecting member 23; a plurality of positioning holes are formed on the plate body of the second positioning plate 261. The second positioning pin 262 is inserted into the auxiliary connecting member 22, and the positioning holes on the second positioning pin 262 and the second positioning plate 261 correspond to each other.

[0059] Referring to Figure 1, the second positioning plate 261 and the main connecting member 21 of this scheme adopt an integrated structure. The second positioning plate 261 is located at the lower end of the main connecting member 21 and is an arc-shaped plate. Several positioning holes are provided along the plate body of the second positioning plate 261. The second positioning pin 262 is a spring pin located on the lower side of the auxiliary connecting member 22. The angle of the auxiliary connecting member 22 can be adjusted by the second positioning assembly 26.

[0060] This solution also provides a chest press trainer, which is mainly used for seated chest press exercises. Referring to Figure 6, it includes a support frame 1, which can be placed on the ground as a basic support structure. The support frame 1 includes a base frame 11 and an upper frame 12. The base frame 11 is in contact with the ground, and a seat cushion 5 and a back cushion 6 are connected to it. The upper frame 12 is fixedly mounted on the base frame 11 and extends upwards from the base frame 11. Two swing arms 3 are provided at the ends of the upper frame 12. The upper ends of the swing arms 3 are rotatably connected to the upper frame 12, and the lower ends are provided with handle adjustment structures 2. The lower ends of the swing arms 3 also serve as the main connecting parts 21 of the handle adjustment structures 2. The handle adjustment structures 2 extend above the seat cushion 5. The swing arms 3 and the counterweight assembly 4 are linked; the swing arms 3 drive the counterweights of the counterweight assembly 4 to move, thereby increasing the load during exercise.

[0061] The counterweight assembly 4 can be set in different forms, such as a hanging plate type counterweight, where a hanging rod is set on the swing arm 3 to hang barbell plates. Figure 6 of this scheme uses another type of counterweight, with a counterweight placement frame set on one side of the base frame 11, and a counterweight block assembly set in the placement frame. The counterweight block assembly adopts the insert connection structure in the prior art, and the swing arm 3 is linked to the counterweight block assembly through a sliding and cable combination.
