1. Field of the Invention
The present invention relates to a wrench, and more particularly to an electrical torsion wrench that has an adjustable visual angle for operator to easily read the operated torsion value.
2. Description of Related Art
A conventional electrical torsion wrench (80) in accordance with the prior art shown in
However, the electrical display (84) is stable relative to the shank (82) such that the operator can not clearly read the number displayed on the window (841) in a great visual angle. It needs to be advantageously altered.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional electrical torsion wrench.
The main objective of the present invention is to provide an improved electrical torsion wrench that has an adjustable visual angle for operator to easily read the operated torsion value.
To achieve the objective, the electrical torsion wrench in accordance with the present invention comprises a shank, an operational head and a handle respectively mounted to two opposite ends of the shank. The handle has a first abutment formed on a distal side and radially corresponding to an axis of the shank. A stick perpendicular extends from the first abutment. An electrical displayer is rotatably sleeved on the shank and axially adjacent to the handle for the operator to easily and clear read the operating torsion value in different visual angles. The electrical displayer has a second abutment formed on a distal side thereof and abutting against the first abutment. A curved groove is laterally defined in the second abutment for receiving the stick such that the rotary range of the electrical displayer is limited.
The screen of the electrical displayer is parallel to the workpiece when the work piece is lower than the horizontal visual angle of the operator. The electrical displayer is turned toward the user's eye's for easily read the operating torsion value when the horizontal height of the workpiece approaches to the horizontal visual angle of the operator. Consequently, the operator can easily and clearly read the operating torsion value in different operational angle due to the rotary electrical displayer.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
Referring to the drawings and initially to
The handle (30) has a first abutment (31) formed on a distal side facing the electrical displayer (40), wherein the first abutment (31) is radially corresponding to an axis of the shank (10). A stick (32) perpendicularly extends from the first abutment (31) and multiple indentations (33) are circumferentially defined in the first abutment (31). The multiple indentations (33) define a circumferential angle being 180 degrees.
The electrical displayer (40) has a second abutment (41) formed on a distal side thereof and abutting against the first abutment (31). A curved groove (42) is laterally defined in the second abutment (41) for movably receiving the stick (32) such that the rotary range of the electrical displayer (40) is limited. The curved groove (42) defines a circumferential angle being 180 degrees. A hole (43) is laterally defined in the second abutment (41). A spring (431) and a steel ball (432) are sequentially received in the hole (43). The steel ball (432) is selectively engaged to a corresponding on the multiple indentations (33) such that the electrical displayer (40) can be rotated relative to the shank (10) step by step.
