Abstract

The utility model relates to an adjustable gripping device which comprises two handles of which the top ends are hinged together. One of the two handles is hinged with spring sleeve rods, and the other end of the spring sleeve rods is penetrated through the hole of the other handle; the outer side of the handle is provided with springs which are sheathed on the end parts of the spring sleeve rods; the end parts of the spring sleeve rods are connected with an elastic force adjusting knob through screw connection; drag ropes which are used for limiting the expansion degrees of the handles are connected with the two handles. Because the utility model can regulate the length of the springs at an initial state by the rotating elastic force adjusting knob to change spring force, the utility model can easily satisfy different exercisers' requirements to enlarge using ranges to obtain the best exercising effect.

Description

Adjustable spring-grip

Affiliated technical field

The utility model relates to a kind of body-building apparatus that is used for hand and finger exercise, particularly relates to the adjustable spring-grip of a kind of spring force.

Background technology

Existing spring-grip mostly is made of handle and spring, and the open angle of the size of its spring force and handle can not be adjusted, and can't adapt to different body builders' needs, is difficult to the train on that reaches best.Though being 00217322 adjustable resistance spring-grip, the patent No. overcome above-mentioned defective, its complex structure, manufacturing cost height.

Summary of the invention

The purpose of this utility model is exactly at the prior art deficiency, provide a kind of can regulating spring power size and spring-grip simple in structure, to adapt to different person taking exercises' needs, improve body-building effect.

The adjustable spring-grip of the utility model has two hinged handles of top, its design feature is to be hinged with the spring loop bar on a handle therein, the end in addition of this spring loop bar passes the hole on another root handle, in the outside of this root handle the spring that is sleeved on the spring housing boom end is arranged, at the spring housing boom end by the elastic force adjusting knob that has been threaded.

Adjustable as mentioned above spring-grip is connected with the drag-line that limits the handle opening angle between two handles.

Because the utility model can be adjusted the length of spring original state by rotation elastic force adjusting knob, thereby changes the size of spring force, thereby can be easy to satisfy different person taking exercises' needs, enlarges accommodation, reaches best train on.And the utility model is simple in structure, and is easy to use, and cost of manufacture is low, is convenient to popularize.

The specific embodiment

Embodiment illustrated in fig. 1, the top of two handles 1,6 of the present utility model is hinged, form a tong-like structure, be hinged with spring loop bar 2 on a handle 1 therein, the end in addition of this spring loop bar 2 passes the hole on another root handle 6, in the outside of this root handle 6 extension spring 4 that is sleeved on spring loop bar 2 ends is arranged, by the elastic force adjusting knob 5 that has been threaded, be connected with the drag-line 3 of restriction handle opening angle on 1,6 on two handles in spring loop bar 2 ends.

Embodiment illustrated in fig. 2, the end of its spring loop bar 2 has external screw thread, and elastic force adjusting knob 5 is for having the nut of internal thread.

Embodiment illustrated in fig. 3, its spring loop bar 2 is for having the tubulose of internal thread, and elastic force adjusting knob 5 is for having externally threaded screw rod.This elastic force adjusting knob 5 also can be formed with the nut that has internal thread that is contained in the screw rod end by having externally threaded screw rod.
