Quick-release torque device

A quick-release torque device, including:

• a main body including a receiving hole, a connecting hole for assembling of a driven member, and a through hole in communication with the receiving hole and the connecting hole, the receiving hole and the connecting hole being respectively opened on opposing sides of the main body;
• an annular magnetic member fixedly received in the through hole;
• and
• a push rod movably inserted within the through hole and the annular magnetic member;
• wherein the main body further includes a handle and a barrel rotatably inserted in the handle, the barrel is integrally formed of one piece, and the barrel includes the receiving hole, the connecting hole and the through hole;
• wherein the main body further includes a partition extending radially and located between the receiving hole and the connecting hole, the through hole is disposed through the partition, and the partition is tapered radially inward;
• wherein the through hole includes a small diameter section in communication with the receiving hole and a large diameter section in communication with the connecting hole, the large diameter section is located between the small diameter section and the connecting hole, a diametric dimension of the connecting hole is larger than a diametric dimension of the large diameter section, an axial dimension of the large diameter section is larger than an axial dimension of the annular magnetic member, and the annular magnetic member is fixed in the large diameter section;
• wherein an annular side face of the annular magnetic member and the main body define an annular gap therebetween, and the annular gap expands radially inward and is conical around the push rod;
• wherein the annular magnetic member includes two openings expanding outward and being conical.
