Abstract: An apparatus for timely and securely locking and releasing a rope includes a housing having an interior space and a communication portion for entering a rope into the housing. The housing includes an abutment portion fixed into the housing, a rotatable cam configured to be corresponsive to the abutment portion and pivotally connected to an inner side of one of the side panels, an elastic member installed between the side panel and the cam, and a rotatable start portion having an engagement surface and a first engagement portion. The rotatable start portion is configured to be corresponsive to an end of the cam and pivotally connected to an end of an inner side of one of the side panels, and an end of the start portion has a second engagement portion corresponding to the first engagement portion.

Abstract: An assembling structure for timely and securely locking and releasing a rope includes a housing including two integral side walls for defining a space to allow a rope to pass through; a contact surface on an inner surface of the housing; a pivotal cam including an occlusion section and an engagement surface adapted to pivot about the contact surface from a first position to a second position and vice versa; a torsion spring on one pivot of the cam and having one end fastened in the cam and the other end passing through a limit member of the cam; and a pivotal trigger adapted to pivot about the housing from a third position to a fourth position and vice versa, the trigger including an occlusion member at one end in gear engagement with the occlusion section and a lever at the other end and extending out of the housing.

Abstract: A system and method for using pinyin and a dynamic memory state for modifying a Hanyu vocabulary test are provided. The system uses a Chinese input method for conducting the Hanyu vocabulary test, and includes an input device, an output device, a computing processing device, and a word database. The computing processing device includes a user login verification unit, a screening and sampling unit, a grading and timing unit, and a recording and analyzing unit. The user uses the input device and output device to operate the system. After the user is verified by the user login verification unit, the screening and sampling unit samples a test bank from the word database based on the test record of the user. The grading and timing unit calculates the answering time and determines if the user has answered the questions correctly. The recording and analyzing unit records and analyzes a test result of the user, and then stores the test result to the word database.

Abstract: A multifunction car wash gun including a car wash gun body, a connector, an adjustment mount, a sleeve, a setting sleeve, and a nozzle. The connector is fastened to the car wash gun body and has a water passage formed that is in continuity with the water passage in the car wash gun body. A soap solution output hole of the water passage is situated in the lower receptacle. The adjustment mount is installed at the bottom end of the connector. The sleeve is filled with a soap solution and installed into the lower receptacle. A liquid wax chamber is attached between the connector and the car wash gun body. A user can directly rotate the adjustment mount to selectively control water flow stoppage, water-only output, a combination water and soap solution output, and a combination water and liquid wax output.

Abstract: A water pipeline foreign matter obstruction remover having an interior space, the water output hole of a water output head at the center of the top end, a water hose connector at the bottom section, and a connector seat that conjoins the top section with the water output head. A number of water output openings are situated along the approximate middle section of the water output head and contained within the area between the water output head and the connector seat is a water output nozzle and a water output seat having a rotary water output head. A water output passage is situated along the interior of the water output nozzle, with the nozzle discharging from the center of the top section. Rotary cleaner arms are positioned at the top section, with a water output passage situated at the middle section.
