A bolt catch assembly for a firearm lower receiver having a symmetrical and ambidextrous finger pad in an ergonomic location at the front of the trigger-well which operates the catch and release function of the bolt catch. The finger pad moves in a vertical motion; up to catch the bolt, and down to release the bolt. It may be operated from the left or the right finger pad by a left-hand finger or a right-hand finger. The finger pad is affixed to a vertical link which has a tooth at its top end which engages a groove on the edge of the bolt catch to make the bolt catch pivot. The vertical link includes an elongated slot that accommodates a magazine release shaft.

1. The name of the design product: the main body of the split keyboard proportional interactive graphical user interface for electronic devices. 2. The use of the design product: an electronic device. 3. The design points of the design product: the part in the graphical user interface, the part outside the dotted line is the claimed part. 4. The picture or photo that best shows the design points: design 1 front view. 5. Design 1 is designated as the basic design. 6. The use of the graphical user interface: the overall appearance design of the interface is used to display the split keyboard of the input method under the horizontal screen, and the split keyboard is conveniently separated through gesture interaction, and different proportional split keyboard interactions; the use of the local appearance design of the interface is the same as the overall use. 7. The human-computer interaction mode of the graphical user interface: in design 1 front view, the user's left and right thumbs slide to the middle area of the interface at the same time (when the user holds the device with both hands), and the keyboard returns to the default state; it can also click the rectangular split icon in the toolbar area above the keyboard, so that the keyboard returns to the default state. The human-computer interaction mode of designs 2 to 4 is the same as that of design 1. In design 5 front view, when the user clicks the rectangular split icon in the toolbar area above the keyboard, or (when the user holds the device with both hands) the left and right thumbs slide to the left and right side areas of the interface at the same time, and then lifts the fingers, the keyboard separates to the left and right sides of the interface, and presents the interface change from design 5 front view to design 5 interface change state view. In design 6 front view, (when the user holds the device with both hands) when the user's left and right thumbs slide to the left and right side areas of the interface at the same time, and the sliding distances of the left and right hands are different, the sliding distance of the right hand is obviously longer than that of the left hand, and then the fingers are lifted, the keyboard separates to the left and right sides of the interface, and the number of key blocks on the right side is more than that on the left side, and presents the interface change from design 6 front view to design 6 interface change state view. In design 7 front view, (when the user holds the device with both hands) when the user's left and right thumbs press the left and right side areas of the interface at the same time, the right finger does not move, the left finger slides to the left, and then the finger is lifted, the keyboard separates to the left and right sides of the interface, and the number of key blocks on the left side is more than that on the right side (left main right auxiliary), and presents the interface change from design 7 front view to design 7 interface change state view. In design 8 front view, (when the user holds the device with both hands) when the user's left and right thumbs press the left and right side areas of the interface at the same time, the right finger does not move, the left finger slides to the left for a long distance, and then the finger is lifted, the keyboard separates to the left and right sides of the interface, and the number of key blocks on the left side is more than that on the right side (left main right auxiliary), and presents the interface change from design 8 front view to design 8 interface change state view. In the design 9 front view, when the user's left and right thumbs slide from the left and right sides of the interface to the middle of the interface (the user holds the device with both hands), the keyboard returns to the default state, and the design 9 front view presents the interface change of the design 9 interface change state diagram. The human-computer interaction mode of design 10 is the same as that of design 9.

To provide a fastener in which a hooking object is hardly detached even when an external force is applied.SOLUTION: In a fastener, a left hook body 21 and a right hook body are overlapped and pivotally supported in a part between a front side plate part having an opening part 6 and a rear side plate part 7, energization is performed by a spring member 60 in a direction of closing the opening part 6, a left hook part 24 is opened when a left finger hook part 30 of the left hook body is pressed, a right hook part is opened when a right finger hook part 50 of the right hook body is pressed, a hooking object can be inserted to the inside of the opening parts 4, 6, and the left hook part 24 and the right hook part are hooked on the hooking object by the spring member 60 when it is released.SELECTED DRAWING: Figure 4
