Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a massage head quick replacement structure and a massager thereof. Background Technique

[0002] A massager acts on the human body through physical stimulation to achieve the purpose of relaxing the body muscles. The massager needs to be used with a massage head. Different shapes of massage heads have different functions, including round heads, single cylindrical heads, double cylindrical heads, flat heads, and so on.

[0003] For example, a connecting rod for inserting into the inside of the telescopic end of the fascia gun is provided at the end of the fascia gun. The connecting rod is inserted into the inside of the telescopic end, and then the high-frequency telescoping of the telescopic end will drive the connecting rod to telescopic together, thereby driving the massage head to telescopic together. This method is to sleeved a rubber sleeve on the outer wall of the connecting rod when it is inserted into the telescopic end. The rubber sleeve plays a role of clamping and increasing the connection tightness when the connecting rod is inserted into the telescopic end. However, this connection method will cause a large resistance when the connecting rod is inserted into or pulled out from the telescopic end, and there is also a problem that the telescopic end is often pulled out of the cavity during the extraction.

[0004] Compared with the way of rotational massage, the way of installing the massage head in this telescopic massage method is relatively simple. If the massage head is to achieve massage by rotating, the method of fixing with a silicone sleeve cannot be realized. Content of the Utility Model
