Abstract
A detachable protective device includes a base support, a mounting unit connected to the base support, and a quick-release unit. The base support has a mounting hole having an engaging portion and an open end portion. The quick-release unit includes a positioning pin extending movably through the mounting hole. The quick-release unit is operable to move the positioning pin between a locked position, where a large-diameter section of the positioning pin is disposed in the engaging portion, and a release position, where a small-diameter section of the positioning pin is disposed in the engaging portion, thereby allowing separation of the mounting unit from the base support.

A detachable protective device adapted to be used with a table saw, the table saw including a table and a saw blade that extends transversely through a top surface of the table, said detachable protective device comprising:
- a base support adapted to be fixed to the table and adjacent to the saw blade, said base support having a mounting hole that extends therethrough along an axis, said mounting hole having an engaging portion through which the axis passes, and an open end portion which is disposed at a side of said engaging portion in a direction perpendicular to the axis and which has a width smaller than that of said engaging portion;
- a mounting unit detachably connected to said base support;
- two protective covers swingably disposed on said mounting unit for covering part of the saw blade;
- and
- a quick-release unit disposed on said mounting unit, and including a positioning pin that extends along the axis and that extends movably through said mounting hole, said positioning pin having
- a large-diameter section that extends along the axis and that has a diameter larger than the width of said open end portion of said mounting hole, and
- a small-diameter section that is connected to said large-diameter section, that extends along the axis, and that has a diameter smaller than the width of said open end portion of said mounting hole;
- wherein said quick-release unit is operable to move said positioning pin relative to said base support between a locked position, where said large-diameter section is disposed in said engaging portion of said mounting hole and is not allowed to be removed from said mounting hole via said open end portion of said mounting hole, thereby securing said mounting unit to said base support, and a release position, where said small-diameter section is disposed in said engaging portion of said mounting hole, thereby allowing separation of said mounting unit from said base support through removal of said small-diameter section from said mounting hole via said open end portion of said mounting hole.
