Chest-developer：Also known as grip stick, one kind of sports apparatus, according to using when needs power size be divided into it is different etc. Level, typically have 20,30,40,50, the several ranks of 60kg, the apparatus can be used for tempering arm muscle group, have certain danger, no It is recommended that the children of less than 12 years old use.It is for tempering arm muscle group, mainly tempers arm strength and chest muscle, auxiliary exercise wrist power.Mesh , following defect be present in preceding existing body-building chest-developer:1st, handle easily comes off because of perspiration rubber sleeve, the peaces such as folder meat folder hair be present Full hidden danger；2nd, it is easily deformed after spring is used for multiple times, degree of enduring hardships is poor；3rd, dynamics is unadjustable, and arm strength can not be in proper order when exercising It is progressive, lack sports fun；4th, bar for arm strength building exercise motion is single, it is impossible to preferably reaches all round exercise effect.

Utility model content：

In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of multi-functional adjustable dynamics arm strength Device.

Multi-functional adjustable dynamics chest-developer of the present utility model.It includes refined spring 1, bayonet connection 2, clamp button of the spring 3rd, fixed screw 4, thickening iron core tube 5 and the handle 6 with NBR foams, the both ends of spring 1 are refined by bayonet connection 2 with adding The clamp button of the spring 3 of the thick inner side of 5 front end of iron core tube two connects and fixes, and fixed screw 4 is tight with thickening iron core tube 5 by refined spring 1 Gu the front end that iron core tube 5 is arranged on the handle 6 with NBR foams is thickeied, and the rear end for thickening iron core tube 5 is applied in NBR foams Handle 6 inside, and the handle 6 with NBR foams in being symmetrically installed setting two-by-two.

Preferably, the outside of described refined spring 1 is coated with foam, the quantity of described refined spring 1 is two.

The beneficial effects of the utility model：It can overcome the drawbacks of prior art, and this product adds NBR foam handles, Absorbing sweat is anti-skidding, comfortable feel；And fixed using dual spring, multiple spot, strengthen product structure intensity and degree of enduring hardships；This product spring It is connected with handle by fixed card buckle, can requires that sets itself tempers weight according to different user；This product can not only temper chest Portion, abdominal muscles, moreover it is possible to temper wrist, leg and muscle of back, improve chest-developer train on.

Brief description of the drawings：

For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.

Fig. 1 is the utility model structure diagram.

Embodiment：

As shown in figure 1, present embodiment uses following technical scheme:It include refined spring 1, bayonet connection 2, Clamp button of the spring 3, fixed screw 4, iron core tube 5 and the handle 6 with NBR foams are thickeied, refine the both ends of spring 1 by snapping connection Part 2 connects and fixes with thickening the clamp button of the spring 3 of the inner side of 5 front end of iron core tube two, and fixed screw 4 by refined spring 1 and thickeies iron Core pipe 5 fastens, and thickeies the front end that iron core tube 5 is arranged on the handle 6 with NBR foams, and the rear end for thickening iron core tube 5 is applied in Inside the handle 6 of NBR foams, and the handle 6 with NBR foams is in be symmetrically installed setting two-by-two.

Preferably, the outside of described refined spring 1 is coated with foam, the quantity of described refined spring 1 is two.

The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
