Description

TECHNICAL FIELD The present disclosure relates to a field of percussion massagers, and in particular to a spiral pull and insert structure of a massage head. BACKGROUND Massage devices, especially handheld massagers, are widely used in our daily lives. The massage devices can relieve muscle fatigue, promote blood circulation, and relax the body and mind, and usually include massage heads that have various shapes and functions. Therefore, the massage effect on different parts and needs can be achieved. Conventional massage heads are mostly mounted in a screw fixation manner, a snap connection manner, or a direct inserting and pulling manner. Although the screw fixation manner is firm, the mounting and removal processes are cumbersome and performed via tools. This is not convenient enough. In addition, the massage head needs to withstand a specific pressure and torque during the use. If the massage head is not firmly mounted or has poor coaxality, the massage head is easy to loosen, offset, or even fall off. This affects the user experience, and may damage the massage head. SUMMARY In view of this, it is necessary to provide a spiral pull and insert structure of a massage head to resolve the above problem. The spiral pull and insert structure of a massage head includes a massage head, a sliding rod holder, and a screw, where a first groove is provided on the massage head, an end of the first groove includes a thread, a second groove is provided on the sliding rod holder, an end of the screw includes a thread, the sliding rod holder is sleeved on the massage head, the screw is disposed inside the first groove and the second groove, and a size of the screw matches a size of the first groove and a size of the second groove. Preferably, a diameter of a portion, disposed inside the first groove, of the screw is larger than a diameter of the second groove. Preferably, an edge of the second groove is chamfered. Preferably, a fixing sleeve ring is sleeved on the massage head. Preferably, at least one annular protrusion is disposed on an outer side of the fixing sleeve ring, the sliding rod holder is sleeved on the massage head, and an annular groove is provided in a region abutting against the fixing sleeve ring, and the annular groove matches the at least one annular protrusion. Preferably, an abutting portion is disposed at a position, in contact with the massage head, of the fixing sleeve ring, and when the sliding rod holder is disposed on the massage head, an edge end of the sliding rod holder abuts against the abutting portion.
