A safety blood lancet device includes an outer sleeve. A fixing tube fixed in the outer sleeve has a cantilever hook. A carrier is elastically inserted into the fixing tube, and in which a lancet is separably installed at a front end thereof, a rear tip which is at a rear end of the outer sleeve and connected with a rear end of the carrier so as to load the carrier by pulling the carrier toward a rear side. A female nut is separably coupled to the outer sleeve. A front tip is rotatably installed at a front end of the female nut and in which a needle of the lancet protrudes through a front end thereof when the carrier is shot. A rear end of the fixing tube is selectively inserted into a safety cap and is elastically installed toward a front side of the outer sleeve.

Safety blood lancet device

A hard disk drive including an actuator arm to pivot across a disk and having a read/write head disposed at an end of the actuator arm to read data from the disk and to write data to the disk, and a crash stop to prevent the read/write head from being pivoted beyond a preset outermost position of the disk. The crash stop can include a housing coupled to a base of the disk drive and disposed adjacent to an outer circumference of the disk, and a buffer member forcibly coupled to the housing. A coupling groove can be provided on one of the housing and the buffer member and a coupling protrusion can be provided on the other one of the housing and the buffer member to precisely locate the read/write head at the preset outermost position of the disk when the actuator arm contacts the crash stop.
