It needs to be explained that whether the piston 111 or the massage head 120 is provided with injection molding threads or the nut 121, and the standard nut 121 is preferred and can save cost and reduce processing difficulty, and the structure of the first screw joint and the second screw joint is not limited in some other embodiments of the utility model.
[0046] In an embodiment, the fascia gun 100 further comprises a first fastener 130, the first fastener 130 is sleeved on the massage head 120 or the piston 111, and the massage head 120 and the piston 111 abut the two ends of the first fastener 130 respectively.
[0047] As shown in the utility model one embodiment, Figures 1 to 4As shown in another embodiment of the utility model, fascia gun 100 still includes first fastener 130, specifically, first fastener 130 is silica gel washer, this silica gel washer is set on first stud 1111 or second stud 122.When first fastener 130 is set on first stud 1111, the screw hole depth of the nut 121 in massage head 120 is greater than the depth of first stud 1111, to reserve enough space for first stud 1111, after the rotation of massage head 120 in place, it is clamped to the piston 111 and is tightly closed first fastener 130, first fastener 130 occurs elastic deformation and provides pre-tightening force to the thread, to make the thread of first stud 1111 and nut 121 bite tightly each other, avoid the situation that massage head 120 loosens after long time use. Same, please refer to Figure 4 , first fastener 130 is set on second stud 122, in this scheme, first fastener 130 is also clamped by massage head 120 and piston 111, so that the thread of second stud 122 and threaded hole 1112 is locked. In conventional fascia gun, some massage heads with relatively large weight, silica gel extrusion has the risk of automatically bouncing out in use, and screw connection does not.
