Figure 3 is a schematic view of the transparent ring disposed on the torque tool.

Fig. 4 is a partially enlarged view of the torque tool of Fig. 3.

Fig. 5 is a cross-sectional view of Fig. 4.

As shown in the first and second figures, the transparent ring 10 has a first end 11 and a second end 13 , and an amplifying portion 12 and an engaging portion 16 are designed between the first end 11 and the second end 13 . A through hole 20 extending axially along the transparent ring 10 passes through the amplifying portion 12 and the engaging portion 16. Therefore, the transparent ring 10 is substantially annular, and a convex portion 14 is raised at a portion of the transparent ring 10 between the enlarged portion 12 and the engaging portion 16.

The enlarged portion 12 is externally formed with a convex curved surface 18 that abuts the first end 11 of the transparent ring 10. The convex curved surface 18 is convex regardless of the cross section along the axial direction of the transparent ring 10 or the cross section along the radial direction of the transparent ring 10. In addition, the engaging portion 16 is externally formed with a circumferential surface 15 which abuts the second end 13 of the transparent ring 10. The difference is that the cross section of the circumferential surface 15 along the axial direction of the transparent ring 10 is a plane, and the cross section along the radial direction of the transparent ring 10 is a convex surface. In this manner, the convex portion 14 is integrally formed with the convex curved surface 18 and the circumferential surface 15.

In the present embodiment, the convex portion 14 is a ring-shaped pyramid ring, and the end surface of the convex curved surface 18 is connected by the inclined surface with the vertical surface of the pyramidal ring abutting the end portion of the circumferential surface 15. In some embodiments, the protrusions 14 may be of other geometric designs, such as a circular or polygonal ring shape.

It is then seen that the through hole 20 distinguishes between three sections: a small diameter section 22, a conical section 24 and a large diameter section 26, the two ends of which extend to the small diameter section 22 and the large diameter section 26, respectively. among them, The small diameter section 22 passes through the first end 11 of the transparent ring 10, which is inside the enlarged portion 12, and cooperates with the convex curved surface 18 to form a part of the thickness of the transparent ring 10. The large diameter section 26 passes through the second end 13 of the transparent ring 10, which is inside the engagement portion 16, and cooperates with the circumferential surface 15 to form part of the thickness of the transparent ring 10.

One of the two ends of the conical section 24 is defined as a reduced diameter end 21 having a diameter greater than the diameter of the small diameter section 22, and a toroidal surface 25 joining the reduced diameter end 21 to the end of the small diameter section 22. The other end of the conical section 24 is considered to be the enlarged diameter end 23 and is connected to the large diameter section 26, and the enlarged diameter end 23 is inclined toward the reduced diameter end 21 such that the conical surface of the conical section 24 and a virtual line passing through the reduced diameter end 21 The 27 clip has an angle 28 which ranges from 1° to 10°.

In Figs. 3 to 5, the specific structure of a torsion tool 30 having the transparent ring 10 is illustrated by a support member 32, a grip 34 and an operating portion. The support member 32 has a scale group 33 on the outside, and the sub-scale group 33 includes some scales and values, such as Arabic numerals in metric or imperial units. The grip 34 is disposed on one of the two ends of the support member 32 for movement (e.g., rotation or displacement) relative to the support member 32. The grip 34 has a front section 34A and a rear section 34B for positioning a knob 38 that is displaceable by the grip 34. The front section 34A is hollow to shield the sub-scale set 33 of the support member 32, and a plurality of major scales 31 and a number 35 are arranged on the surface of the front section 34A, each number 35 being opposite the corresponding major scale 31.

Further, the operation portion is connected to the holder 32 and is not at the same end as the grip 34. The operation portion has a choice of the following mode: the operation portion 36A is fixed to the head of the support member 32, and the head portion has a post 36C for inserting a sleeve (not shown). Therefore, the torque tool 30 is a torque wrench.

The operating portion 36B is a driving end of a figure, a cross or other geometric shape. As such, the torque tool 30 acts as a torque driver.

Next, when the transparent ring 10 is placed over the outside of the support member 32, the engaging portion 16 is covered by the grip 34 so that the convex portion 14 can abut against the end surface of the grip 34. The amplifying portion 12 surrounds the front portion of the grip 34 The 34A and the support member 32 are adjacent to the grip 34, and the main scale 31 and the sub-scale group 33 are enlarged near the main scale 31.

The cover referred to herein may be a wrapped or forced structure. In short, the grip 34 is usually produced by injection molding a polymer material such as plastic, and of course can be wrapped and attached to the outer surface of the engaging portion 16. As for the pressing structure, it is meant that the end surface of the grip 34 is pre-formed with a groove having a width smaller than the thickness of the engaging portion 16, and the engaging portion 16 is pressed into the groove of the grip 34 to cause an urgent coupling. The relationship also enables the transparent ring 10 to be combined with the grip 34.
