Upper limb strength training can be performed through the handle 3, the pull rope 2 and a plurality of counterweights 11; 2. A part of the load can be reduced first through the buffer group to solve the problem of muscle or ligament pulling caused by overload of the counterweight 11 for novice operators; 3. The limit slot 211 and the limit pin 7 can be used to switch between the novice mode and the normal use mode to avoid misoperation during training that leads to load reduction and improve practicality.

[0022] See also Figures 1 to 5 Preferably, the buffer group of the utility model is symmetrically arranged, and a fixing plate 312 is fixedly connected between the two inner rods 31, and a limit pin 7 is passed through the fixing plate 312; a limit block 71 is provided at the end of the limit pin 7, and the limit block 71 is arranged in the limit groove 211, and the limit groove 211 is arranged on the cylinder 21, which can limit the cylinder 21 from moving relative to the fixing plate 312.

[0023] See also Figures 1 to 5In addition, the inner rod 31 of the present invention is provided with a main elastic member 311 on its outer sleeve, and the main elastic member 311 abuts against the fixing plate 312 .

[0024] See also Figures 1 to 5 Furthermore, the handle 3 of the utility model is provided with an observation hole 32, the cylindrical pin 41 is arranged in the observation hole 32, and the push rod 42 is provided with a secondary elastic member 43.

[0025] See also Figures 1 to 5 Better yet, the other end of the pull rope 2 of the utility model is provided with a plurality of counterweight blocks 11.

[0026] Working principle:

[0027] In the normal mode, the limit pin 7 is rotated to drive the limit block 71 to be set in the limit slot 211, and the limit block 71 is perpendicular to the slot hole of the limit slot 211, ensuring that the cylinder 21 is fixed to the fixing plate 312. The operator holds the handle 3 and pulls the counterweight 11 through the pull rope 2 to perform strength training;

[0028] In novice mode, the limit pin 7 is controlled to rotate 90°, and the limit block 71 is parallel to the slot hole of the limit slot 211. When the counterweight block 11 is overloaded, the push rod 42 is pressed. At this time, the secondary elastic member 43 is forced to compress, and the push rod 42 and the cylindrical pin 41 are respectively fixed to the two ends of the block 4. The push rod 42 drives the cylindrical pin 41 to disengage from the pin hole 511, and the counterweight block 11 drives the cylinder 21 to fall back through the pull rope 2. The cylinder 21 pulls the two connecting rods 6 to drive the two long rods 5 to move. The main elastic member 311 can slow down the falling speed of the counterweight block 11, ensuring that the counterweight block 11 falls slowly while reducing the falling impact force of the counterweight block 11 to avoid muscle or ligament damage to the user.
