For example, when an external force is applied to the pressing portion 3280, the locking member 3250 is driven to gradually move away from the adjusting member 3240, so that the locking member 3250 is separated from the adjusting member 3240, and at this time, the adjusting member 3240 is no longer limited by the locking member 3250, and can move towards the through hole direction under the action of a restoring force of the restoring member 3270, so that the connecting band is released; when an external force is applied to the pressing portion 3280 and drives the locking member 3250 to gradually approach the adjusting member 3240, the locking member 3250 is connected and engaged with the adjusting member 3240.
In other embodiments, the pressing portion 3280 may be further configured as a cam, and specifically, a cam may be disposed on the inner wall 3211 of the housing 3210, a rotating shaft of the cam extends out of the housing 3210 and is connected to a knob as the pressing portion 3280, the cam is driven to rotate by rotating the knob, when a contact position of the cam and the locking member 3250 is within a range of a push angle of the cam, the cam drives the locking member 3250 to move toward a direction of the reset member 3260, so that the locking member 3250 gradually moves away from the adjusting member 3240 until disengaging, when the contact position of the cam and the locking member 3250 is within a range of a return angle of the cam, the locking member 3250 gradually approaches the adjusting member 3240 until connecting with the adjusting member 3240, and when the locking member 3250 is connected with the adjusting member 3240, the cam and the locking member 3250 disengage.
In addition, in other embodiments, a user can press the pressing portion 3280 to enable the adjusting member 3240 to be matched with the locking member 3250, and then slide the pressing portion 3280 to enable the adjusting member 3240 to slide relative to the locking member 3250, so as to tighten the connecting band 310; when the user removes the force applied to the pressing portion 3280, the adjuster 3240 is locked such that the adjuster 3240 cannot move relative to the latch 3250.
Referring to fig. 4, 5 and 7, in the embodiment, the resetting element 3260 is located between the locking element 3250 and the adjusting element 3240 and located on a side of the locking element 3250 away from the pressing portion 3280, the resetting element 3260 is disposed in the accommodating cavity 3220 along the pressing direction of the pressing portion 3280 and is configured to provide a resetting force to the locking element 3250, the pressing portion 3280 is configured to enable the locking element 3250 to be selectively connected to or separated from the adjusting element 3240, when an external force is not applied to the pressing portion 3280, the restoring force of the resetting element 3260 enables the locking element 3250 to be connected to the adjusting element 3240, and when the external force is applied to the pressing portion 3280, the pressing portion 3280 drives the locking element 3250 to compress the resetting element 3260 and overcome the resetting force, so as to enable the locking element 3250 to be separated from the adjusting element 3240.
In some embodiments, referring to fig. 3 again, the resetting element 3260 may include a first resetting element 3261 and a second resetting element 3262, and specifically, referring to fig. 4 and 5 again, the first resetting element 3261 and the second resetting element 3262 extend in a direction substantially perpendicular to the axial direction of the through hole 3230, two ends of the first resetting element 3261 abut against the locking element 3250 and the housing 3210, and two ends of the second resetting element 3262 abut against the locking element 3250 and the housing 3210, respectively, the first resetting element 3261 and the second resetting element 3262 are spaced apart from each other, and when the first resetting element 3261 and the second resetting element 3262 are compressed, the first resetting element 3261 and the second resetting element 3262 both apply a force to the locking element 3250 to make the locking element 3250 approach the adjusting element 3240, so that the locking element 3250 tends to approach the adjusting element 3240, thereby driving the locking element 3250 to be coupled with the adjusting element 3240.
In addition, relative positions of the latch 3250, the first reset element 3261 and the second reset element 3262 may be adjusted, so that the first reset element 3261 and the second reset element 3262 respectively abut against two ends of the latch 3250, the pressing portion 3280 may be located between the first reset element 3261 and the second reset element 3262, a moment generated by the pressing portion 3280 and the first reset element 3261 acting on the latch 3250 at the same time may partially offset a moment generated by the pressing portion 3280 and the second reset element 3262 acting on the latch 3250 at the same time, and a situation that the latch 3250 is tilted when the pressing portion 3280 acts on the latch 3250 may be avoided as much as possible. Specifically, in this embodiment, the first and second reset members 3261 and 3262 can be springs, and the housing 3210 and the locking member 3250 have mounting holes at corresponding positions, and the springs are disposed in the corresponding mounting holes. With the above structure, when the latch 3250 compresses the first and second reset members 3261 and 3262, the first and second reset members 3261 and 3262 are not twisted excessively to generate a force parallel to the direction of the through hole 3230, so that the first and second reset members 3261 and 3262 are damaged, and the latch 3250 cannot generate an original reset force to fail. In other embodiments, the first and second returning elements 3261 and 3262 can be made of other elastic materials, such as elastic rubber.
With reference to fig. 4 and fig. 5, in the present embodiment, the resetting element 3260 may further include a third resetting element 3263, the third resetting element 3263 is located between the first resetting element 3261 and the second resetting element 3262, for example, the distance between the third resetting element 3263 and the first resetting element 3261 may be equal to the distance between the third resetting element 3263 and the second resetting element 3262, and the third resetting element 3263 is increased to increase the resetting force of the resetting element 3260 on the locking element, so that the locking element is not easily disengaged when the locking element is connected to the adjuster.
In addition, referring to fig. 4 and fig. 9 again, in order to ensure the stability of the pressing portion 3280 during the pressing process, in some embodiments, a first slider 3212 and a second slider 3213 may be disposed on the inner wall 3211 of the housing 3210, the first slider 3212 and the second slider 3213 may be disposed opposite to each other, the extending directions of the first slider 3212 and the second slider 3213 may be substantially parallel to the axial direction of the pressing hole 3218, and the pressing portion 3280 is slidably disposed between the first slider 3212 and the second slider 3213, so that the pressing portion 3280 may move along the extending direction of the sliders, thereby avoiding the locking member 3250 from tipping.
In other embodiments, the housing 3210 protrudes outward at the pressing hole 3218 for a distance to form a channel communicating with the pressing hole 3218, the cross-sectional shape of the channel is adapted to the cross-sectional shape of the pressing portion 3280, the pressing portion 3280 protrudes out of the channel through the mounting hole, and a small gap exists between the pressing portion 3280 and the channel to avoid the pressing portion 3280 contacting the channel excessively and obstructing the movement of the pressing portion 3280 along the extending direction of the channel.
Referring to fig. 4 again, in this embodiment, the adjusting mechanism 320 further includes a sliding key 3290 for driving the adjusting element 3240, meanwhile, the housing 3210 may further include a sliding slot 3214 communicating with the accommodating cavity 3220, an extending direction of the sliding slot 3214 is substantially parallel to an axial direction of the through hole 3230, the sliding key 3290 is connected to a fixing rod, the sliding key 3290 is slidably disposed in the sliding slot 3214 through the fixing rod, a portion of the fixing rod extending into the accommodating cavity 3220 through the sliding slot 3214 is connected to the adjusting element 3240, so that the sliding key 3290 drives the adjusting element 3240 to slide in the accommodating cavity 3220 when sliding in the sliding slot 3214, and the adjusting element 3240 drives the connecting band 310 to move to adjust the tightness of the connecting band 310.
