[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, this utility model comprises a main rod, a handle, a training component, and a counterweight ring. A pressure sensor is installed in the moving groove inside the main rod, and moving openings are provided at both ends of the moving groove. When the patient needs to exercise grip strength, they can hold the handle and the pull rod of the training component. The patient's fingers pull the pull rod, causing the pull rod to move the connecting rod inside the moving opening. This causes the compression plate to push the compression spring and the bonding plate to press against the pressure sensor. The pressure value is displayed on a screen electrically connected to the pressure sensor, facilitating both grip strength exercise and numerical observation. When the patient needs to use dumbbells, the counterweight ring can be fitted onto both ends of the main rod, and then the patient can hold the main rod to exercise.

The collar is attached to the grip, and four springs with different elastic forces are set on the outer side of the collar. Each spring is connected to a support plate at its end. When the patient performs grip strength training, the collar is rotated, causing the springs with different elastic forces to rotate the support plates above the traction rod. Subsequently, when the patient clenches their hand and moves the traction rod, they will encounter different resistances. This allows for easy adjustment of the resistance during grip strength training based on the patient's recovery progress, facilitating adjustments to the training intensity and improving the training effect.
