[0026] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all, based on the embodiments in the embodiment, other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.

[0027] As Figures 1-3 Indicated, the utility model provides a kind of delay wearing's screw knob structure, including first cylinder 1, limiting piece 4, second cylinder 2 and positioning block 3;

[0028] First cylinder 1 outer edge is along the direction of its axis and is provided with at least one first sliding slot 11 and at least one second sliding slot 12, one second sliding slot 12 is communicated with one first sliding slot 11 and is L-shaped, circular slot 13 is formed in the inner wall of second sliding slot 12 along the direction of the axis of first cylinder 1;

[0029] Limiting piece 4 is rotatably arranged in circular slot 13;

[0030] Second cylinder 2 one end is provided with the opening 21 of the size adaptation of first cylinder 1;

[0031] The inner wall of the opening 21 of second cylinder 2 is fixed with at least one positioning block 3, and the positioning groove 31 is formed in the side of the inner wall of the opening 21 of the positioning block 3 away from the opening 21 along the direction of the axis of second cylinder 2;

[0032] Wherein, first cylinder 1 is relatively rotated after entering second cylinder 2, limiting piece 4 moves to positioning groove 31 when positioning block 3 moves from first sliding slot 11 to second sliding slot 12, and positioning block 3 is attached to the inner wall of second sliding slot 12;

[0033] When it is necessary to assemble the first cylinder 1 and the second cylinder 2, the positioning block 3 is aligned with the first slide groove 11, and the first cylinder 1 is inserted into the opening 21 of the second cylinder 2 until the positioning block 3 is aligned with the second slide groove 12. Then, the first cylinder 1 and / or the second cylinder 2 are rotated forcefully to allow the positioning block 3 to gradually enter the second slide groove 12 until the limiting member 4 enters the positioning groove 31, thereby completing the fixing of the positioning block 3, that is, completing the assembly and fixing of the first cylinder 1 and the second cylinder 2. Since the limiting member 4 is rotatably located in the arc groove 13, during this process, the limiting member 4 rolls along the outer surface of the inner wall of the opening 21 of the second cylinder 2 opposite to the positioning block 3. Thus, the rolling friction between the limiting member 4 and the positioning block 3 replaces the sliding friction caused by the existing sliding snap, thereby greatly reducing the friction force and significantly reducing the wear of the limiting member 4, thereby improving the service life of the snap fastener structure.

[0034] The top and bottom surfaces of the positioning block 3 are aligned with the top and bottom surfaces of the inner wall of the first slide groove 11, thus ensuring that the positioning block 3 will not move along the central axis of the first cylinder 1, making the two more stable.

[0035] like Figure 1 and Figure 2 As shown, the limiting member 4 is detachably installed in the arc groove 13, so that when the limiting member 4 wears out after long-term use, it can be easily replaced.

[0036] Specifically, the limiting member 4 is cylindrical and moves through the second sliding groove 12 and one end face of the first cylinder 1, but does not pass through the other end of the first cylinder 1. The end face of the first cylinder 1 is provided with a threaded hole 14, and the threaded hole 14 is provided with a screw 5. The screw 5 has a screw rod and a nut. The screw rod is located in the threaded hole 14. When the nut is in contact with the end face of the first cylinder 1, the nut partially or completely covers the opening of the arc groove 13 (the figure shows the example of the nut partially covering the opening of the arc groove 13).

[0037] When the limiting member 4 needs to be replaced, unscrew the screw 5 to disengage the screw from the threaded hole 14, so that the limiting member 4 can be removed from the arc groove 13 along the central axis of the first cylinder 1. Then, insert the new limiting member 4 into the slot of the arc groove 13 on the end face of the first cylinder 1. Then, use the screw 5 to align the screw with the threaded hole 14 and screw it in until the nut is in contact with the end face of the first cylinder 1. At this time, the nut partially or completely covers the slot of the arc groove 13, thereby blocking the limiting member 4 and ensuring that it will not disengage from the arc groove 13.

[0038] like Figure 1 As shown, the length of the limiting member 4 is less than the length of the arc groove 13;

[0039] By so arranging, the limiting piece 4 can have a gap with the nut and / or the bottom wall of the circular-arc groove 13, so that when the limiting piece 4 rotates, the friction between the limiting piece 4 and the nut and / or the bottom wall of the circular-arc groove 13 is reduced, thereby further reducing the abrasion of the limiting piece 4 when the first cylinder 1 and the second cylinder 2 are disassembled.

[0040] When the circular-arc groove 13 and the positioning groove 31 are combined, the outer wall of the limiting piece 4 does not contact the inner wall of the circular-arc groove 13 and / or the positioning groove 31, so that although the tightness of the connection between the first cylinder 1 and the second cylinder 2 is reduced, the contact area between the limiting piece 4 and the inner wall of the circular-arc groove 13 is further reduced, thereby further reducing the abrasion of the limiting piece 4 when the first cylinder 1 and the second cylinder 2 are disassembled.

[0041] Here, the limiting piece 4 is made of stainless steel, which is more wear-resistant than the existing plastic protrusions on the first cylinder 1.

[0042] As shown in Figure 3 The positioning block 3 and the second cylinder 2 are integrally injection molded, which is efficient in production and reduces the trouble of assembling the two.

[0043] As shown in Figures 1-4 A massager (for example, a fascia gun in the figure) includes a shell part 6 and a massage part 7, the shell part 6 is provided with a power supply, the massage part 7 is provided with a transmission mechanism, and the specific transmission mechanism includes a motor and a cam reciprocating structure, the cam reciprocating structure is connected to a massage head, which is the existing structure of the movement of the fascia gun, and the specific working principle is not described here, the power supply is electrically connected to the transmission mechanism (for supplying power to the motor), a screw buckle structure is arranged between the shell part 6 and the massage part 7, a first cylinder 1 or a second cylinder 2 is arranged at the end of the shell part 6 opposite to the massage part 7, and a second cylinder 2 or a first cylinder 1 is arranged at the end of the massage part 7 opposite to the shell part 6 (for example, the first cylinder 1 is fixed in the shell part 6, and the second cylinder 2 is fixed on the massage part 7), so that the assembly and disassembly of the shell part 6 and the massage part 7 of the fascia gun are facilitated, and the power supply in the shell part 6 or the transmission mechanism in the massage part 7 is facilitated to be repaired or replaced.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
