In the present embodiment, three tool heads 14, a positioning device 16, and an operating member 18 are separately mounted on the first surface 24 and the second surface 25 of the base 12. In another embodiment (see Figure 7), the tool head set 10 includes only three tool heads 14, a positioning device 16, and an operating member 18 mounted on the first surface 24 of the body 12. Since the first surface 24 and the tool head 14, the positioning device 16, and the operating member 18 on the second surface 25 are the same or similar structures, only the tool head 14, the positioning device 16, and the operating member on the first surface 24 will be described below. 18 to explain. Each of the tool heads 14 is a hexagonal drive head of a different size, however, each of the tool heads 14 can be a flat, plum, or cross drive head. Each of the tool heads 14 includes a joint end 36 and a drive end 37 that can be inserted into the bore of the screw head. The joint end 36 has an annular outer surface 38 and a shaft bore 39. The three tool heads 14 are separated by a liner ring 40 and are arranged between the two side panels 22 along the length. The shafts 29 extend through the coupling holes 28 of the two side panels 22 and the shaft holes 39 of the tool heads 14 such that the tool heads 14 are rotatable relative to the seat body 12 about an axis defined by the shafts 29. Further, the outer surface 38 of the joint end 36 of each of the tool heads 14 is provided with a plurality of positioning grooves 41 partitioned in the peripheral direction.

In particular, the operating member 18 is normally in the first position and the outermost portion 52 of each of the positioning beads 43 abuts against one of the positioning grooves 41 of the outer surface 38 of the coupling end 36 of the tool head 14, so that the tool heads The 14 series is rotatably folded into the recesses 32, 33 of the seat body 12. On the other hand, when the second section 58 of the biasing operating member 18 moves the operating member 18 to the second position, the user of the 201242894 can rotate the selected size or type of tool head 14 to a desired operation. Angle (can be 90 degrees, 135 degrees, 180 degrees, or other angles as shown in Figure 6). After the tool head 14 is rotated to the desired operating angle and the user releases the force applied to the second section 58 of the operating member 18, the spring force of the spring 60 biases the operating member 18 to the first position, thereby causing the tool head 14 Positioned to provide locking or loosening of the screw. By adjusting and positioning the operating angles of the tool heads 14, the tool heads 14 can meet the requirements of different operating environments, and the user can operate the turning operation more smoothly, and can reduce the tightening or loosening of the workpiece. The power exerted. A variety of variations and modifications can be made in the spirit of the invention, and obvious substitutions and modifications may be made by those skilled in the art, which are still within the scope of the claimed invention.
