Abstract: The instant disclosure relates to an angle adjustable device, which includes: a base having a fixing member disposed thereon, where the fixing member has a fixing surface; a switch mechanism having a locking ring, a first gear, and a second gear, while at least one block protrudes from the inner surface of the locking ring, with the first gear having a contact incline slidingly abutted by the block, where the contact incline is defined with a first end and a second end, where the first gear is received by the locking ring and capable of meshing with the second gear; and a rotator having at least one connecting member connected to the second gear. The instant disclosure also discloses an electronic display unit using the same.

Abstract: An data search apparatus includes: a storage unit, storing a plurality of data; an input unit, inputting a data name, selecting a plurality of preference sets, and inputting a grading set by a user; a process unit, receiving the data name for searching for a plurality of candidate data from the data stored in a storage unit and generating a ranking result.

Abstract: A holding support for electronic device is disclosed, which includes a case and a bracket. A bracket compartment is formed on the case and defined by an opening formed on the outer surface of the case. The bracket has a body and at least one finger hole formed thereon for sliding a finger through. The bracket can be retracted in or extended from the bracket compartment by being arranged at a retracted position or extended position, respectively. Therefore, the user can firmly secure the electronic device and prevent from dropping it accidentally.

Abstract: A platform and a method for dynamic software license are disclosed. The dynamic software license platform comprises a license pool, a register manager, a user configure unit and a license manager. The register manager receives a software application from a user end. The user configure unit grants a setting permission to the user end in response to the software application, and allows the user end to submit a license setting according to the setting permission. The license manager adds the software license provided by the software supplier to the license pool, and dynamically provides the software license from the license pool unit according to the license setting.

Abstract: A coupling head and connecting tube assembly structure comprises a coupling head having an external-threaded section to fit to a connecting tube wherein the coupling head has a hollow bore extending through the interior to which the connecting tube is joined therewith. Furthermore, the connecting tube has the internal surface synchronically pressed by multiple dotted-punching forces so that the internal surfaces of both connecting tube and coupling head synchronically depressed by the dotted-punching forces exerting thereon can form multiple positioning points that are reciprocally bound to each other so as to combine the coupling head and connecting tube into one unit, facilitating easy and speedy assembly thereby.

Abstract: A telescopic tube with water supply is equipped with a minor tube, a major tube that are connected to each other by a tubular coupling device which has a registration end and a connecting section, the former is engaged with one end of the minor tube and the latter is engaged with the top end of the major tube. A guard cap is secured to the top end of the major tube which serves to prevent the minor tube from easy disengagement from the major tube in case of excessive extension adjustment. The connecting section of the tubular coupling device has a cone shaped configuration with a spiral thread track defined thereon and terminates in a stop board.

Abstract: A long-handled spray gun with a rotary head has a connector head, a rotary member, a fixed member, a connection, part, a long tubular rod, a block, a fixing bolt, a large and a small ring washers and a flexible locating member wherein the rotary member screw joined to the connector head at one side is pivotally engaged with the fixed member with the large and small ring washers adapted therein and the flexible locating member inserted into one of locating slots of the rotary member for proper location thereof, and the connection part is coupled with the fixed member and the long tubular rod at both ends respectively. The fixing bolt is adapted to pivotally engage the rotary member with the fixed member thereof and the block having a serrated polygonal flange disposed thereon is matched to a serrated polygonal fixing head of the fixed member, preventing the fixing bolt from coming off when the rotary member thereof are pivotally rotated.
