DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-7 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 7 As shown, the utility model discloses a vibrating massage stick with a replaceable massage head, comprising a stick body 1 and a massage head 4. Figure 2 As shown, one end of the rod body 1 is connected to a connecting rod 2, and as shown Figure 3 As shown, the massage head 4 includes an integrally formed head 41 and a connecting root 42, and as shown in FIG. Figure 1 As shown, the head 41 of the massage head 4 of the utility model can have a variety of shapes, but the connecting root 42 of all the massage heads 4 is the same, and a socket 43 for inserting the connecting rod 2 is opened on the connecting root 42, and at least one positioning bayonet 44 is radially opened on the inner side wall of the socket 43 of the connecting root 42, and a positioning clamping column 3 for inserting into the positioning bayonet 44 is provided on the connecting rod 2, and a control component for controlling the positioning clamping column 3 to extend and retract the connecting rod 2 is provided on the rod body 1. When the massage head 4 is connected to the rod body 1, the connecting rod 2 of the rod body 1 is inserted into the socket 43 in the connecting root 42 of the massage head 4, and then the positioning clamping column 3 on the connecting rod 2 is extended and inserted into the positioning bayonet 44 through the control component, so that the massage head 4 can be effectively prevented from falling off, and when the massage head 4 needs to be removed, the positioning clamping column 3 is also controlled by the control component to retract into the connecting rod 2, that is, the connecting rod 2 can be pulled out from the socket 43.

[0027] There are two symmetrical positioning slots 44 on the inner side wall of the insertion hole 43 , and two corresponding positioning posts 3 are also provided, which can further improve the connection strength between the connecting rod 2 and the connecting root 42 .

[0028] Specifically, the control assembly includes a rotating sleeve 5 rotatably arranged on one end of the rod body 1 close to the connecting rod 2. Figure 5 As shown, a rotating rod 51 is connected to the inner side of the rotating sleeve 5, and a rotating groove 11 is provided on the rod body 1 for the rotating rod 51 to rotate at least 90°, and a driving member for driving the positioning column 3 to extend is connected to the end of the rotating rod 51 away from the rotating sleeve 5. Specifically, the driving member includes a cam 6, the rotating rod 51 is fixedly connected to the cam 6, and a movable notch 21 is provided in the connecting rod 2, the positioning column 3 is slidably set in the movable notch 21, and a limiting plate 31 is provided at one end of the positioning column 3 located in the movable notch 21, and a compression spring 32 located on the limiting plate 31 is sleeved on the positioning column 3, and the compression spring 32 is used to push the positioning column 3 to move toward the movable notch 21, and the compression spring 32 makes the positioning column 3 fit on the surface of the cam 6 as the cam 6 rotates.

[0029] Further, such as Figure 6 and Figure 7As shown, the cam 6 is elliptical and has a first plane 61 and a second plane 62 on the cam 6. The first plane 61 and the second plane 62 are symmetrically arranged. When the positioning column 3 conflicts with the first plane 61, the positioning column 3 extends out of the movable slot 21. When the positioning column 3 conflicts with the second plane 62, the positioning column 3 retracts into the movable slot 21. The arrangement of the first plane 61 and the second plane 62 is conducive to the positioning column 3 being able to maintain the state of extending or retracting in the movable slot 21 when it is in contact with the first plane 61.

[0030] In addition, in order to enable the positioning column 3 to more stably maintain the state of extending or retracting in the movable groove 21, the cam 6 is provided with a positioning groove 63 on the first plane 61 and the second plane 62, and the positioning column 3 is provided with a steel ball 34 groove 33 on the end facing the cam 6. The steel ball 34 is movably arranged in the steel ball groove 33, and a steel ball spring 35 for pushing the steel ball 34 outward is also provided in the steel ball groove 33. When the positioning column 3 is in contact with the first plane 61 or the second plane 62, the steel ball 34 enters the steel ball groove 33, which can further maintain the state of the positioning column 3 and the cam 6. It should also be noted that in order to facilitate the rotation of the rotating sleeve 5, a plurality of stripes can be provided on the outer surface of the rotating sleeve 5.

[0031] In addition, the utility model Figure 2 and Figure 3 As shown, an anti-rotation protrusion 22 is integrally formed on the side wall of the connecting rod 2, and an anti-rotation slot 45 for inserting the anti-rotation protrusion 22 is opened on the inner wall of the insertion hole 43 of the connecting root 42. When the connecting rod 2 is inserted into the insertion hole 43, the anti-rotation protrusion 22 is inserted into the anti-rotation slot 45, which further improves the connection strength between the connecting rod 2 and the connecting root 42.

[0032] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
