Abstract

The invention discloses an adjustable hand-muscle developer. The adjustable hand-muscle developer comprises a first supporting arm and a second supporting arm, the first supporting arm is of an L type and comprises a long arm and a short arm, the second supporting arm is of a linear type, a fulcrum is arranged at the L-type bending position of the first supporting arm, and the top end of the second supporting arm is rotationally connected with the fulcrum; the included angle between the second supporting arm and the short arm is an obtuse angle, and the included angle between the second supporting arm and the long arm is an acute angle. A tension spring is arranged in the short arm, and a pull rod is arranged at the top end, close to the fulcrum, of the second supporting arm. The adjustable hand-muscle developer has the advantages of being capable of overcoming defects in the prior art and reasonable and novel in structural design.

Description

technical field [0001] The invention relates to an adjustable grip and belongs to the field of sporting goods. Background technique [0002] Gripper is a kind of personal exercise equipment used to improve arm strength. It is easy to carry and cheap, and is very popular among users. Currently, the grips in use generally include a pair of handles facing each other and elastically supported by a spring, if the user uses a force greater than the force of the spring to grip the pair of handles, the handles move closer to each other, and If the user releases the grip on it, the grips return to their original state due to the elastic force of the spring, and by repeating this gripping and releasing operation, the muscular strength of the arm can be exercised and the strength of the arm can be improved. However, after the frequent tightening process of the gripper, its resistance will become worse, that is, people only need to use a small force to grip it tightly, so after a perio...
