The present invention provides a pressable locating device and a driving mechanism thereof, and more particularly to a locating device which can be used to combine two plates by a pressing manner; when using the locating device, a shaft base is assembled with a first preset plate, a sleeve of the driving mechanism is assembled on a second preset plate, and the sleeve and a pressing unit of the driving mechanism are assemble on the shaft base, so as to achieve the purpose of locating or separating the first preset plate and the second preset plate by operating the pressing unit.
Many items for general daily life often apply locating structures (such as screws or pins) for locating items during the reciprocating process; for example, drawers or cabinet panels, which have telescopic structures, usually utilize screw rods or pins to temporarily locate the sliding rails or sliding slots when the sliding rails and sliding slots are moved to predetermined positions, so as to allow the user to perform operation under the stop and locating statuses of the sliding rails and sliding slots. For example, desktop computers, notebook computers, industrial computers or working machines which are made by assembling multiple devices and mechanisms usually utilize screws or pins to locate two plates in a stacked state, so that a plate member which can be movably assembled and disassembled can be disposed on the housing of the mechanism, or multiple devices and mechanisms can be easily assembled or disassembled.
However, a user may be injured inadvertently when touching a tip and thread of the screw and the pin; when disassembling the device, the mechanism or the plate, the user must remove the screws or pins first, and it may cause the problem of losing the screws or pins; when the user does not have backup screws and pins and just use the remaining screw or pin for assembly, it results the unstable assembly status of the mechanism and the plate after assembly, and the assembled mechanism and the plate are easy to loosen and detached. Furthermore, when many screws or pins are placed in the same position after being disassembled, it may not easy to find the corresponding screw or pin for assembly. In addition, a hand tool (such as a screwdriver or a wrench) is required to remove the screws or the pins, and when the types of the screws or pins are different, the user needs to prepare different hand tools, and it may cause the problem that the assembly and disassembly operations become unsmooth. Due to the above-mentioned problems and deficiencies in actual use, using screws or pins to fasten and locate the plates in stack has extremely inconvenient deficiencies.

However, in the above-mentioned conventional fastening device, the restraining member B3 is fastened inside the accommodating groove A1 of the base A and it is not easy to inspect whether the long cut sides B14 on the two sides of the sliding rod B13 are aligned or misaligned to the two shrinking side edges B31 of the restraining member B3, so the user must distinguish an aligning status between the long cut sides B14 on two sides of the sliding rod B13 and the two shrinking side edges B31 of the restraining member B3 upon hand feeling when rotating the rod head B4 to drive the locating rod B1 to rotate, and it causes the blind spot in use and is unfavorable to operate the conventional fastening device. The sliding rod B13 of the locating rod B1 is covered by the elastic member B2, so the locating rod B1 may be shaken and deflected in an unstable status by resistance of the elastic member B2 when the user holds and rotates the rod head B4 to drive the sliding rod B13 of the locating rod B1 to move in the restraining hole B30 of the restraining member B3; furthermore, when the rod head B4 is rotated to align the long cut sides B14 of the sliding rod B13 to the two shrinking side edges B31 of the restraining member B3, the elastic member B2 pushes the locating rod B1 to move out of the through hole A0 of the base A by an elastic force, so the rod head B4 held by the user may suddenly escape from the user's fingers to impact the base A, and directly collide with the base A and the restraining member B3; after the long time use, the above-mentioned problem may cause the base A to skew easily and the locating rod B1 not to directly expose out of the base A to align with a locating hole C0 of a plate C, and it is unfavorable to combine and fasten the two plates C. Therefore, the above-mentioned conventional fastening device has some drawbacks in actual application.
