Abstract
A quick release structure for use in the saw blade guard assembly of a table saw is disclosed to include a mounting member affixed to the base of the table saw, a coupling block detachably attached to the mounting member to hold a pivoted attachment member, for example, a saw blade guard, and a rotary locking member mounted in the coupling block and rotatable relative the coupling block between two positions to lock the coupling block to the mounting member or to release the coupling block.
Claims12
A quick release structure comprising:
- a mounting member having a body with a retaining hole;
- a coupling block having a clamping groove for fastening to the body of said mounting member and a through hole in communication with said clamping groove;
- and
- a rotary locking member having a rod body pivotally inserted in the through hole of said coupling block and provided with a retaining portion at an end thereof engaging said retaining hole of said mounting member, and a pushable portion at the other end thereof rotatable by an external force to move said retaining portion to be disengaged from said retaining hole of said mounting member;
- wherein the retaining hole of said mounting member is formed on the body of said mounting member near a top side of said body;
- the through hole of said coupling block is a stepped through hole having an upper section and a lower section, said lower section having a diameter greater than said upper section;
- the retaining portion of said rotary locking member is a protrusion head and the pushable portion of said rotary locking member is a lug rotatable between a first position where the protrusion head of the rotary locking member is pivotally engaged into the retaining hole of said mounting member and a second position where the protrusion head of the rotary locking member is pivotally disengaged from the retaining hole of said mounting member.
