The invention belongs to the technical field of optical microscopic imaging, and particularly relates to a single objective lens light sheet microscopic imaging system, which comprises an exciting light modulation light path, a fluorescence detection light path and a microscopic imaging system, and is characterized in that the exciting light modulation light path is used for generating an illumination light sheet to excite fluorescence, and specifically comprises a laser, a beam expanding collimating lens group, a modulator, a scanning system and the like. The microscopic imaging system is used for transmitting an illumination light sheet and collecting light emitted by a sample, and comprises a dichroscope, a galvanometer module, an image rotating system, a tubular lens, an objective lens and the like. And the fluorescence detection light path comprises a relay lens group, a modulation element, a band-pass optical filter, a camera and the like. According to the invention, tasks of light sheet illumination and fluorescence collection in a traditional double-objective light sheet microscope are completed through a single objective, a remote focusing system or a micro-mirror reflection structure commonly used in an existing single-objective light sheet microscope does not need to be used, and a light sheet orthogonal to a focal plane is adopted for illumination. Compared with the existing light sheet microscope technology, the method has higher usability and flexibility, allows free switching of objective lenses under the condition of not changing other light paths, is compatible with any objective lens and various samples, does not need any software processing including deskewing in the principle of an obtained image, can directly display and use an original image, and is high in practicability. The system has higher resolution and is close to ideal isotropic imaging when various objective lenses are used for imaging.

This invention provides a rubber band launching device, comprising: a gun body and a launching system, a feeding system, and a power system for powering the movement of the entire device, all mounted on the gun body. The launching system is mounted on the gun body via a fixed bracket and includes a main shaft, a fixed wheel, a first rocker arm, a rotating wheel, a rubber band hook, and a second drive wheel. The rotating wheel rotates around the fixed wheel and also rotates on its own axis, thereby driving the rubber band hook to perform a pulling and releasing action. The feeding system uses a belt-fed method; when the second drive wheel rotates one revolution, the feed wheel rotates one tooth pitch, thus actuating the belt to feed bullets one by one. This invention features safe loading, simple operation, and prevents finger injuries when installing rubber bands. It can freely switch between single-shot and fully automatic burst modes, and has a large ammunition capacity, allowing for the continuous firing of a large number of rubber bands, enabling players to fully enjoy the fun of shooting and offering high replayability.
