1. A torque socket comprising:
- an inner socket being interiorly provided with an axially movable positioning ball, a spring and a radially movable loading ball, the positioning ball and the loading ball being pushed against each other, and the loading ball being allowed to partially protrude out of the inner socket; and
an outer socket axially including a holding groove in one end thereof, the holding groove of the outer socket being formed with a ratchet surface on an inner periphery thereof, on the ratchet surface being equidistantly provided plural annularly-arranged teeth, the respective teeth including two side surfaces, and a resisting surface connected between the two side surfaces, between two opposite side surfaces of each two neighboring teeth being formed a U-shaped engaging recess with respect to the ratchet surface, the outer socket being allowed to be pivotally engaged on the inner socket, when the loading ball is engaged into the one of the engaging recesses, the outer socket and the inner socket will be fixed relative to each other, when the loading ball is pushed against by one of the resisting surfaces of the teeth, the outer socket and the inner socket are allowed to pivot relative to each other;
by such arrangements, during a pivoting process of the inner socket and outer socket, the loading ball will move into and out of the inner socket due to its position changes with respect to the engaging recesses and the teeth, and when the loading ball passes over the teeth and engages into the engaging recess, a sound will be produced.

Abstract
A torque socket essentially comprises an inner socket, and an outer socket. Besides a function of torque value setting and adjustment, the torque socket utilizes a ratchet structure design to produce a sound to warn the user, when the torque applied by the torque socket has reached a predetermined value, allowing the user to know the torque applied to the fastener by the torque wrench has reached the predetermined value easily. Further, the torque socket is simple in structure, thus reducing the production and assembly cost.
