Abstract: A board fixing module fixes a board to a base body. The board fixing module includes: a fixing element embedded into the base body, a bottom portion passed through the board and a latch element latched with the fixing element, and a passing rod passed into the latch element for maintaining the latch condition of the latch element and the fixing element. The invention is characterized in that users simply need to press the passing rod inward to release the latch condition of the latch element and the fixing element in order to separate the board from the base body, and thus the invention achieves the effect of a convenient installation or dismount.

Abstract: The present invention discloses a latch module installed at a joint position between two plates for connecting and assembling the two plates. The latch module includes a fixing element embedded into a joint surface of a first plate, a positioning base embedded into a second plate, and a turning element installed in the positioning base and being turnable accordingly, and exposed from a joint surface of the second plate for engaging the joint surface of the first plate and the joint surface of the second plate, such that the connection between the first plate and the second plate can be secured. If it is necessary to dismount the latch module, the turning element is turned in an opposite direction to release the latch between the positioning portion and the fixing element.

Abstract: A combinational commodity engaging unit which can connect by engaging plates of a computer desk, a TV cabinet etc. in order to assemble the combinational commodity without using an auxiliary tool, the engaging unit includes at least: a fixing seat embedded in a first plate, a hollow engaging member embedded in a second plate and having its bottom portion engaged in the fixing seat, and a fixing rod extended into the interior of the hollow engaging member to maintain the hollow engaging member in a state of engaging the fixing seat. By combination of the above stated fixing seat, hollow engaging member and fixing rod, the combinational commodity can be assembled without using an auxiliary tool.

Abstract: A retaining member structure. The structure includes a retaining rod member and a joint clamping member used to retain two object members. The joint clamping member extends between the jointed surfaces of two object members and the upper thereof has receiving slots, and the lower thereof has resilient clamping plates, and the center thereof has a through round hole which is provided for the retaining rod member to extend into, to make a retaining rod extend outside the resilient retaining plate and to further push the plate open to push against the inside of the inner insert hole of an object member, to assemble the retaining member engaged by the retaining rod member and the joint clamping member for fastening two object members. The retaining rod member and the joint clamping member can be separated to withdraw from two object members.
