Figure 3 is The cross-sectional view taken along the line AA in the stereoscopic ^ 3 of the case. The figure 4 is the figure [embodiment] 1 to 4 is not 'basically, the torque type screwdriver of the present case is a handle 1, and A driving rod 2 is combined. ', wherein the handle 1 is a rod body, and the upper end thereof has a force of, for example, a plurality of parallel protruding ribs arranged in a ring shape to facilitate the operator's finger. Holding and rotating, in fact, the 1 rib is limited, and it is transferred to the conventional embossing or depression groove, which is only a matter of skill, and will not be described here. 曰2, and the handle of the case is different. It is known that the lower end axis = the hole 12, so that the two are passed through a conventional Ϊ / into a hinge structure with a stagnant positioning effect. The shaft hole 12 is a 皆-shaped hole, and the internal corresponding shaft column 22 When the flange portion 222 is positioned and the two or two portions 121 are formed, the flange portion 222 is fastened and received in the joint 121, so that the shaft post 22 is sleeved with the shaft hole 12, and the buckle is formed.

The surface of the cylinder is horizontally at least—the slit 221, which provides the elasticity of the shaft 7 M327270. The shaft column 22 has a flange portion 222 on the surface thereof, and a central portion and a column groove 223' communicate with the slits 221, and the inside thereof can be woven to pass through the slits 221 to form a full-slip effect. In particular, ^ 994 has a ', for example, milling cutter--oil storage slab around each slit 221 for oil storage, and can increase the smoothness during rotation. In the case of the 27th, the shaft column 22 and the shaft hole 12 can be smoothly connected, so that the shaft is provided with a chamfer 225 and 123' at the entrance end when the shaft is avoided. 22 Between the shank 1 and the driving rod 2 , through the shaft hole 12 and the shaft column, as shown in the figure after the fastener is buckled, that is, the screw driver as shown in Fig. 3; ^ Case: = when the lens first = value, the vehicle is locked, and the ^ 'And when the torque value exceeds the pre-decision, the shaft hole 12 will be in the shaft column 22 * = = circumference = 1st due to the lock does not " buckle = by: = from the groove, can be accommodated The turbid oil exporting trough in the case is expanded.
