Abstract: A field-of-view stitching system including: a light source module for emitting a first beam; a light guiding element for splitting the first beam into a plurality of second beams and includes an incident surface, a first exit surface, and a plurality of second exit surfaces, the second beams propagate along an optical path of the first beam; and a plurality of light modulators, a number of the plurality of light modulators is the same as a total number of the first exit surface and the plurality of second exit surfaces, each of the plurality of light modulators is configured to receive and regularly reflect one of the plurality of second beams; the light guiding element is further configured to receive and combine the second beams reflected by the light modulators to form an illuminating light. A field-of-view stitching method, a biological sample identification device and method are also provided.

Abstract: A spring assist system for a canopy frame. The system including an extension spring, an upper center cap, and a lower center cap. One end of the extension spring is coupled to the upper center cap and the other end is coupled to the lower center cap. A force of the extension spring draws, in an axial direction, the lower center cap toward the upper center cap to decrease a length of the extension spring.

Abstract: A snap-in and support structure of a tent support is disclosed that includes a tube piece, a tube holder, a handle, a stop piece, and a locking sleeve. A handle slides in an axial direction opposite to that of the tube holder. A locking sleeve includes a boss integrally formed on an inner circumferential wall. The boss has a slidably coupled inner surface and a top surface. The slidably coupled inner surface on a first side ascends from a bottom to a top of the inner circumferential wall. The tube piece is vertically slidable in an axial direction opposite to that of the tube holder and the handle. A first locking pin transversely slides against the slidably coupled inner surface and stops above the top surface and is proximal to a second side of the slidably coupled inner surface in a locking state.

Abstract: The utility model discloses a clamping and supporting structure of tent support, including a tube piece, a tube holder, and a handle arranged under the tube holder. The bottom of the tube piece passes through the tube holder and the handle and can extend oppositely. A locking sleeve is fixed with the tube holder and provides an inner wall of the locking sleeve is provided with a boss including a guide inclined surface is formed on a first side and ascends spirally from the bottom to the top. The tube piece is provided with a first locking pin and a second locking pin and can move opposite to the tube holder and the handle in the vertical direction and keep the trend of extending oppositely: the first locking pin is propped against the guiding inclined surface, and the second locking pin keeps the trend of propping against the stop piece.
