The outer surfaces of the two adjusting bolts 2208 are fixedly connected with anti-disengagement rings 2218, and the two anti-disengagement rings 2218 are rotationally connected in the interiors of the two adjusting blocks 2204. The anti-disengagement rings 2218 can limit the positions of the adjusting bolts 2208 in the interiors of the adjusting blocks 2204 without affecting the rotation of the adjusting bolts 2208, and prevent the adjusting bolts 2208 from being disengaged from the adjusting blocks 2204.

[0025] The specific implementation of the embodiment is that when the sports trainer does bench press training and forces the piston 2106 to slide upward inside the telescopic cylinder 2104, the piston 2106 can send the hydraulic oil at the upper part of the telescopic cylinder 2104 into the inside of the oil storage tank 2201 through the backflow pipe 2205, the adjusting block 2204 and the oil delivery pipe 2203, and the hydraulic oil in the inside of the oil storage tank 2201 can re-enter the telescopic cylinder 2104 through the connecting pipe 2202.

Then, by rotating the adjusting screw 2208 manually and cooperating with the limiting of the anti-dropping ring 2218, the adjusting plate 2207 can be forced to slide inside the adjusting block 2204, gradually sealing the communication between the backflow pipe 2205 and the oil delivery pipe 2203, so as to limit the flow amount of the hydraulic oil. With the decrease of the flow space of the hydraulic oil inside the adjusting block 2204, the difficulty of the upward sliding of the piston 2106 in the telescopic cylinder 2104 will be further increased, so as to increase the bench press difficulty of the push rod 2108, increase the bench press strength of the trainer, and enable the training device to adjust the training strength according to the training needs of different sports trainers, so that the sports training device can increase the training strength as the strength of the trainer increases, thereby always maintaining the training effect on the sports trainer. When the piston 2106 moves downward to reset, the hydraulic oil in the inside of the oil storage tank 2201 flows into the inside of the telescopic cylinder 2104 through the one-way valve 2206 and the backflow pipe 2205, preventing the reset of the piston 2106 from being affected by the adjusting block 2204. When the adjusting plate 2207 moves, it can drive the pointing frame 2210 to slide, thereby pointing to different positions on the first scale mark 2209. By changing the scale value, the trainer can conveniently adjust the bench press strength of both sides to be consistent, or increase or decrease the bench press strength of one side of the push rod 2108 as needed, so that table tennis players and badminton players and other training personnel with different training strength of both arms can strengthen the training of the weaker arm to improve body coordination. Then, by connecting the block 2216 with the rotating shell 2212, the adjusting screw 2213 and the limiting ring 2211, the push rod 2108 can be ensured to move up and down smoothly with the sliding rod 2105 and the piston 2106. By using the rolling of the ball 2217, the stability and smoothness of the upward and downward movement of the push rod 2108 can be ensured. By rotating the adjusting screw 2213, the connecting block 2216 and the push rod 2108 can be adjusted up and down. By rotating the limiting ring 2211 inside the rotating shell 2212, the sliding rod 2105 will not be affected by the rotating force. By adjusting the push rod 2108 up and down, the distance between the push rod 2108 and the bench 13 can be adjusted according to the body type of the patient, so that different body type trainers can adjust the bench press distance according to their arm length when doing bench press training, thereby further increasing the functionality and adaptability of the sports training device.When the push rods 2108 are adjusted up and down, the pointer 2215 can be driven to point to different positions of the second scale mark 2214, so that the accuracy and coordination of the up and down adjustment of the two push rods 2108 can be ensured according to the numerical value of the second scale mark 2214.
