At least one base plate is mounted in the concave space and includes a horizontal top portion for pivotally fixing a positioning sleeve and a longitudinal portion formed with at least one hanging hole for fixing to an object. Plural suspension members are detachably engaged in the first and second limiting grooves and each provided with an abutting portion to be abutted against the first and second rails, and a retaining portion to be engaged in the first and second limiting grooves.
Abstract:
A dual-purpose fixing stand for a computer screen and a keyboard holder includes: a main body, having an axial pivoting hole disposed at the middle of a distal surface at an end of an axle pivotal disk and a plurality of positioning grooves coaxially disposed around the external periphery of the axial pivoting hole; a universal connector, pivotally and axially coupled to another end of the axle pivotal disk, and a support plate coupled to the universal connector for selectively mounting the computer screen or the keyboard holder; a fixing base, having a support bottom selectively connected to the top or the bottom of a table, and two stand plates convexly disposed with an interval apart and at the top of a distal surface to accommodate and axially and pivotally couple the axle pivotal disk of the main body, and a positioning pin installed individually at positions on the lateral side corresponding to the positions of a plurality of positioning grooves of the axle pivotal disk for providing an elastic extension or retraction and elastically embedded into the positioning grooves to achieve the effect of limiting the position of an axial angle of the main body. Therefore, the fixing stand can be used for fixing a computer screen or a keyboard holder, and users can make an angular adjustment for its operation to enhance the users' operating comfort.
Abstract:
An improved simple inclined-hole drilling jig comprises a jig body having a crossover plane at the bottom that can evenly press against the wood workpiece, and a beveled end member at the front. The beveled end member is concavely disposed with a guiding shaft hole, which extends downwardly from the beveled end member through the crossover plane. The upper end of guiding shaft hole is pivotally configured with a guide bushing for drill bit to pass through. The rear end and side surfaces of jig body are respectively formed with a reference face and sidewalls perpendicular to the crossover plane; where the sidewall is at least concavely disposed with a dust guide groove intercrossing the guiding shaft hole, and is pivotally disposed with a graduated extension board in a manner that allows axial displacement and positioning. The end of the extension board is bent to form a retaining end plane parallel to the reference face to extendingly adjust the axle spread of reference face, thereby greatly enhancing the operating performance of the simple drill jig.
Abstract:
A drill guide used in woodworking for preparing pocket joints includes a guide member with a cuboid body. The cuboid body has an inclined plane formed on a front end thereof and a cavity defined in the front end thereof. The cavity has two opposite ends respectively and slantingly extending to the inclined plane and the first datum plane. A guide sleeve is longitudinally and detachably mounted in the front end of the cuboid body and abuts the inclined plane. The guide sleeve extends into the cavity for guiding a drill bit into the cavity and drilling an inclined hole in the workpiece. The cuboid body has a second datum plane formed on a rear end thereof. An axis of the drill bit passes through a central plane of the workpiece on a rear distal edge when the second datum plane aligns with the rear distal edge.

Abstract:
A multipurpose drilling jig comprises a jig body and a perpendicular stop. The jig body has a plurality of locating holes and a recessed section which is provided for the fitting of a cover plate pressing against a guide sleeve. The jig body and the perpendicular stop are provided with insertion slot mounts for inserting thereinto a plurality of replaceable locating bodies. The locating bodies are provided with a straddling slot. The jig body is provided in two sides with a threaded hole mount which is in turn provided with a locating rib serving as a support for a side locating plate. The side locating plate has a through hole which is aligned with the threaded hole mount to enable the installation by a mounting screw such that the end surface and the lower lateral length of the side locating plate exceeds the height of the jig body to provide a perpendicular support surface serving as standard criterion of positioning, thereby enabling the locating and guidance operation for drilling a wide range of holes to accommodate various types of dowels.

Abstract:
An improved upright drilling jig comprises two parallel panels parallelly mounted on a leveled base platform, and an inclined-hole drilling jig pivotally disposed between the sides of the parallel panels in a manner that it can be vertically adjusted. A sliding saddle is slidably and pivotally mounted at the top of the inclined-hole drilling jig through two axial bars. The rear side of the drilling jig is concavely constricted to form a bow jumper area and disposed with a discharge concavity in a manner approaching a clamping end plane. The discharge concavity has a chip hole inside that communicates with a guide axle hole. Such arrangement can achieve optimum performance of inclined hole drilling of woodwork.
