Abstract

The utility model discloses a novel wrist developer. The novel wrist developer comprises handles and torsion springs, wherein the connecting positions between the handles and the torsion springs are provided with limiting plates, the handles comprise a first handle, a second handle, a third handle and a fourth handle, the torsion springs comprise a first torsion spring, a second torsion spring and a third torsion spring, the first torsion spring is connected between the first handle and the second handle, the second torsion spring is connected between the second handle and the third handle, the third torsion spring is connected between the third handle and the fourth handle, and the diameters of the three torsion springs are different from each other. The novel wrist developer disclosed by the utility model has the biggest advantages that three wrist developing exercises in different strengths can be realized through one wrist developer, the structure is simple, and the use is convenient.

Description

A kind of Novel dynamometer

Technical field

The utility model relates to a kind of hand exerciser tool, relates in particular to a kind of spring-grip for the hand exercise.

Background technology

Spring-grip can be tempered hand strength, fatigue-relieving, and often use can make the hand brawniness, strengthens blood circulation, and small and exquisite being easy to carry about with one, so more welcome.But present spring-grip all only has an intensity can supply to take exercise, and change intensity can only realize by the spring-grip of buying different size.

The utility model content

Technical problem to be solved in the utility model is, a kind of simple in structure, easy to use, spring-grip with three kinds of available exercises of intensity is provided.

for solving the problems of the technologies described above, a kind of Novel dynamometer that the utility model provides, comprise handle and torsion spring, the junction of described handle and torsion spring is provided with banking stop, described handle comprises first handle, second handle, the 3rd handle and the 4th handle, described torsion spring comprises the first torsion spring, the second torsion spring and the 3rd torsion spring, wherein be connected with the first torsion spring between first handle and second handle, be connected with the second torsion spring between second handle and the 3rd handle, be connected with the 3rd torsion spring between the 3rd handle and the 4th handle, and the diameter of described three torsion springs is different.

After adopting above-mentioned measure, the utility model has the following advantages: because the diameter of three torsion springs is different, namely the torsion that produces of three torsion springs is different, namely holds torsion that first handle and second handle produce and holds torsion that second handle and the 3rd handle produce and with to hold the torsion that the 3rd handle and the 4th handle produce different.That is to say, a spring-grip just can be realized the grip exercise of three kinds of varying strengths.

Description of drawings

Shown in Figure 1 is appearance assumption diagram of the present utility model.

Wherein: 1, first handle; 2, second handle; 3, the 3rd handle; 4, the 4th handle; 5, the first torsion spring; 6, the second torsion spring; 7, the 3rd torsion spring; 8, banking stop.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

as shown in Figure 1, this Novel dynamometer comprises handle and torsion spring, wherein handle comprises first handle 1, second handle 2, the 3rd handle 3 and the 4th handle 4, wherein torsion spring comprises the first torsion spring 5, the second torsion spring 6 and the 3rd torsion spring 7, and be connected with the first torsion spring 5 between first handle 1 and second handle 2, be connected with the second torsion spring 6 between second handle 2 and the 3rd handle 3, be connected with the 3rd torsion spring 7 between the 3rd handle 3 and the 4th handle 4, be equipped with banking stop 8 between each torsion spring and each handle, and first torsion spring 5, the second torsion spring 6, the diameter of the 3rd torsion spring 7 is different.

Because the diameter of three torsion springs is different, namely the torsion that produces of three torsion springs is different, namely holds torsion that first handle 1 and second handle 2 produce and holds torsion that second handle 2 and the 3rd handle 3 produce and with to hold the torsion that the 3rd handle 3 and the 4th handle 4 produce different.That is to say, a spring-grip just can be realized the grip exercise of three kinds of varying strengths.

The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.

Claims (1)

1. Novel dynamometer, comprise handle and torsion spring, the junction of described handle and torsion spring is provided with banking stop, it is characterized in that, described handle comprises first handle, second handle, the 3rd handle and the 4th handle, described torsion spring comprises the first torsion spring, the second torsion spring and the 3rd torsion spring, wherein be connected with the first torsion spring between first handle and second handle, be connected with the second torsion spring between second handle and the 3rd handle, be connected with the 3rd torsion spring between the 3rd handle and the 4th handle, and the diameter of described three torsion springs is different.
