Abstract: A fastener including a screw part and a handle part. The screw part includes a head portion and a body portion that are connected to each other. A diameter of the body portion is smaller than a diameter of the head portion. The head portion includes a recess on a side of the head portion located away from the body portion. The handle part is pivotally connected to the head portion and pivotable between an operation position and a bent-down position. When the handle part is in the operation position, the handle part is partially located on a side of the head portion located away from the body portion. When the handle part is in the bent-down position, the handle part is located away from the side of the head portion located away from the body portion.

Abstract: The disclosure provides an adjustable fixing assembly. The adjustable fixing assembly includes a base plate and a cover plate. The cover plate includes a plate portion and a protrusion portion protruding from the plate portion. The cover plate includes a first installation position and a second installation position. When the cover plate is in the first installation position, the protrusion portion extends away from the base plate, and the cover plate is spaced apart from the base plate by a first minimum distance. When the cover plate is in the second installation position, the protrusion portion extends towards the base plate, and the cover plate is spaced apart from the base plate by a second minimum distance, where the second minimum distance is smaller than the first minimum distance.

Abstract: A vehicle safety method includes steps: monitoring a face state of a driver and determining whether the face state satisfies a tired state or not; sensing a physiological state of the driver and determining whether the physiological state satisfies a conscious state or not; sending a warning query when the face state satisfies the fired state and the physiological state satisfies the conscious state; determining whether a response corresponding to the warning query is received or not; and activating a vehicle safety mechanism if the response corresponding to the warning query is not received.

Abstract: The disclosure discloses a quick-detachable fastening assembly including a fixing base, a buckling member, and a plug. The fixing base has an opening and a receiving trough and further has a necking portion in the receiving trough. The buckling member includes a pipe body and a plurality of resilient arms connected to an end of the pipe body. Each of the resilient arms has a buckling block. When the buckling blocks pass through the necking portion, the resilient arms are elastically deformed to move closer to each other. After the buckling blocks are received in the receiving trough, the resilient arms elastically restore. The plug is slidably inserted into the pipe body. When the plug slides relative to the pipe body to extend to the tail ends of the resilient arms, the tail ends abut against the outer surface of the plug.

Abstract: A fixing bracket includes a bracket body, at least one connecting rod assembly, and at least one elastic buckling arm. One side of the bracket body has a first pivoting point and a second pivoting point. The at least one connecting rod assembly includes a first rod, a second rod, a third rod. The first rod has a third pivoting point and a fourth pivoting point. The second rod has a first limiting part, a fifth pivoting point, and a sixth pivoting point. The third rod has a second limiting part, a seventh pivoting point, and a eighth pivoting point. The at least one elastic buckling arm is located on the first rod. The connecting rod assembly drives the elastic buckling arm to move between a release position and a fastening position. When located at the fastening position, the first limiting part is against the second limiting part.
