DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] It should be noted that the description of "first", "second" and the like in the present application is only for the purpose of description and cannot be understood as indicating or implying the relative importance of the technical features indicated or implying the number of technical features indicated. Therefore, the features defined as "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of the person skilled in the art, when the combination of technical solutions appears contradictory or unachievable

[0022] Referring to Figures 1 to 3 The first support 1 is configured as an elastic material, which can be made of PU, PC or PVC, and is provided in the shape of a circular arc similar to the head, so as to be fixed and clamped on the head of the wearer. Of course, this is only a preferred embodiment, and in other embodiments, the first support can also be provided in the shape of a helmet or other head-fitting shape, and such structural changes still fall within the protection scope of the present application.

[0023] The second support 2 includes a first end movably connected to the end of the first support 1 through a damping rotating assembly 3, and a second end for connecting the whistle 5. The whistle 5 is provided on the second end, and the whistle 5 is configured to be moved to the user's mouth by rotating the second support 2. It should be noted that the second support 2 is rotated relative to the first support 1 in the working state, which can also be considered as folding, telescoping and the like. Such changes still fall within the protection scope of the present application.

[0024] By fixing the whistle 5 on the user's head through the first support 1 and the second support 2, when the whistle 5 is needed, the second support 2 is actuated, so that the second support 2 drives the whistle 5 to move to the user's mouth. This way frees the user's hands, and there is no need to continuously hold the whistle 5. Only one step is needed to complete the action of blowing the whistle 5, and the structure is relatively simple and practical, the manufacturing cost is very low, the cost increase for the user is very low, the reliability is relatively strong, and it is convenient for large-scale promotion.

[0025] Specifically, the whistle 5 is configured to be detachably connected to the second end. The second end is provided with an elastic clamping jaw 4, and the whistle 5 is clamped in the elastic clamping jaw 4. By setting the whistle 5 and the second support 2 in a detachable form, the whistle 5 can be replaced at any time, achieving the effect of modular assembly, and for the units that already have the whistle 5, only the support needs to be purchased.

[0026] Further, the elastic clamping jaw 4 comprises a jaw part clamping the whistle 5 from horizontal left and right direction and bottom direction respectively, wherein the clamping jaw of the bottom is provided with a cavity for accommodating the abdomen of the whistle 5. The whistle 5 is fixed in the form of three sides of a sandwich, which improves the stability of the whistle 5 and avoids the whistle 5 from falling when the user performs running, jumping and other actions. Moreover, the cavity can play the role of elastic clamping by shape.

[0027] Further, the damping rotating assembly 3 comprises a rotating disc base 31 fixedly connected to the end of the first support 1 and a rotating disc 32 fixedly connected to the first end, the rotating disc base 31 is movably connected to the rotating disc 32 through a rotating shaft, the top of the rotating disc base 31 is provided with a plurality of radial grooves 33 outward along the axis thereof, and the bottom of the rotating disc 32 is provided with a plurality of radial convex strips 34 outward along the axis thereof, the convex strips 34 can fall into the grooves 33 so that the rotating disc 32 and the rotating disc base 31 are locked. In some other embodiments, the grooves 33 can also be arranged as holes, and the convex strips 34 can be arranged as convex points, and such structural changes still fall within the protection scope of the utility model.

[0028] In some other embodiments, the second support 2 is made of damping material, such as iron wire wrapped with an outer rubber sleeve, so that the shape of the second support 2 can be twisted at will, which is more convenient for the user's use habit.

[0029] Referring to Figure 4 As shown in the embodiment 2 of the utility model hand-free whistle device, the second support 2 comprises at least two support rods movably connected through the universal damping ball head support 6. The arrangement of the two support rods can improve the freedom degree of the end of the whistle 5, which is more convenient for the user to adjust the distance between the whistle 5 and the mouth.

[0030] The above description is only the preferred embodiments of the utility model, and it should be noted that for ordinary skilled in the art, without departing from the principles of the utility model, some improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
