Example 1

Referring to fig. 1, fig. 3 and fig. 4, the present embodiment provides a fastener, which includes a fastener main body 1, a pressure spring 2, a rotating shaft 3, a snap fastener 4 and a limiting component 5 for clamping the snap fastener 4, wherein the fastener main body 1 is hinged to the snap fastener 4 through the rotating shaft 3, the pressure spring 2 is sleeved on the rotating shaft 3, one end of the pressure spring 2 is connected to the snap fastener 4, the other end of the pressure spring 2 is connected to the fastener main body 1, the fastener main body 1 is provided with a placing hole 13 for installing the limiting component 5 and a through hole 11 communicated with the placing hole 13, and the snap fastener 4 passes through the through hole 11 and is clamped to the limiting component 5.

In some embodiments of the utility model, the watch band is provided with the pin buckle to achieve the connection mode of the watch band, and the defect is that the size of the limiting mechanism penetrating through the pin hole is small, so that the leather watch band is contacted with the limiting mechanism to generate large pressure in a long-time use process, and the leather watch band is easy to damage. In addition, in the case of the metal band, for example, the clasp disclosed in application No. CN201922378563.5 is large in volume and complicated in structure, and thus, a wearer feels uncomfortable when wearing the clasp. For this design does not solve above-mentioned problem, adopt to be connected according to the mode of fastener 4 with 1 joint of fastener main part, utilize according to fastener 4 and the direct cooperation of main part 1 with the leather watchband clamp in the centre to the leather watchband to increased the area of contact of watchband with the fastener, can not appear the great condition of certain regional pressure from this, thereby avoided the damage of leather expression. In addition, the transmission mechanism can be reduced by utilizing a clamping mode aiming at the metal watchband, so that the size of the fastener is reduced, and the comfort is improved. The specific embodiment is that the fastener body 1 is hinged with a button 4 through a rotating shaft 3, so as to open and close the watch strap; the button 4 is arranged to penetrate through the through hole 11 to be clamped with the limiting component 5, and after the button is closed, the button is locked to achieve the limiting effect; set up pressure spring 2 simultaneously and provide a great power to fastener main part 1 after the fastener is closed, when spacing subassembly 5 is not carrying on spacingly to snap fastener 4, pressure spring 2 is automatic to be bounced snap fastener 4, has improved the convenience.

Example 2

In some embodiments of the present invention, the fastening element 4 is disposed to facilitate the limiting component 5 to limit the position of the fastening element 4 as much as possible, and because the fastening element 4 is hinged to the fastening element body 1 in this design, the swinging element 41 can only be tilted to perform the through hole 11 during the rotation process, so that the locking is difficult, therefore, the design employs the buckle 42 perpendicular to the swinging arm on the swinging element 41, so that the buckle 42 can vertically enter the through hole 11 after the swinging rotation. The shape of the clip 42 may be T-shaped, L-shaped, etc., and is preferably T-shaped.

Example 3

Referring to fig. 3, the present embodiment proposes based on the technical solution of embodiment 2 that the limiting component 5 includes a spring 52 and a first clip 51 adapted to the buckle 42, the first clip 51 is connected to the fastener body 1 through the spring 52, and the first clip 51 is slidably connected to the fastener body 1 in the placing hole 13.

In some embodiments of the present invention, as for the specific clamping manner of the buckle 42, a manner that the first clamping member 51 slides in the placing hole 13 is adopted to control whether to clamp with the snap fastener 4, wherein in order to fix the first clamping member 51 more tightly when the first clamping member 51 limits the buckle 42, the spring 52 is arranged to apply pressure to the first clamping member 51, thereby ensuring the stability of clamping.

Example 4

Referring to fig. 4, the present embodiment proposes based on the technical solution of embodiment 2 that the limiting assembly 5 includes a spring 52 and two second engaging members 54 adapted to the buckle 42, the two second engaging members 54 are slidably connected to the fastener body 1 in the placing hole 13, and the two second engaging members 54 are connected through the spring 52.

In some embodiments of the present invention, the above-mentioned embodiment is a manner of limiting the buckle 42 by a single clamping member, but the disadvantage of the embodiment is that the single clamping member is also present, and once the clamping member is damaged, clamping cannot be performed. Therefore, the embodiment adopts the mode of arranging the two second clamping pieces 54, and is different from the mode that the spring 52 is directly connected with the fastener body 1 in the embodiment, and the embodiment adopts the spring 52 to connect the two second clamping pieces 54, so that the effect that the fastener can be used even if one clamping piece is damaged is achieved.

Example 5

Referring to fig. 4, the present embodiment proposes based on the technical solution of embodiment 4, further including a shift member 53 for limiting the second engaging member 54, the shift member 53 passes through the fastener body 1 and abuts against the second engaging member 54, and the second engaging member 54 is disposed between the shift member 53 and the spring 52.

In some embodiments of the present invention, after the fastening device 4 is opened, in order to prevent the second open-fastening member from being separated from the fastening device body 1, the blocking member 53 is provided, and the second fastening member 54 is provided between the blocking member 53 and the spring 52, so that the second fastening member 54 is restrained, and the stability is improved.
