In the present creation, the first working portion 11 and the second working portion 22 may be the same or different from each other, and each independently has a hollow inscribed shape, a convex inscribed shape, a hollow cross shape, a convex cross shape, a hollow quadrangular shape, Projecting a quadrangular shape, a hollow pentagon shape, a convex pentagon shape, a hollow hexagon shape, a convex hexagon shape, or other shapes conforming to a fastener shape, for example, a polygon shape with curved sides and curved sides, this creation There are no special restrictions on this.

Next, the rotating operation mechanism and related components of the creative movable wrench tool are further introduced through the exploded view of the second embodiment of FIG. 2 and the accompanying FIG. 1B.

Referring to FIG. 2, a bending rod 10 of a movable wrench tool includes a first working portion 11 extending in a first direction, a short shaft portion 12 extending in a second direction, and a short a rotating portion 13 connected to the shaft portion 12, the rotating portion 13 includes a first sidewall 131 and a second sidewall 132 extending parallel to the second direction, and the first sidewall 131 and the second sidewall 132 are formed A limit groove 133.

The first direction described above is different from the second direction. In other words, the first direction is non-parallel to the second direction but there is an angle. In a preferred embodiment of the present invention, the first direction and the second direction have an angle of slightly 90°, but the angle range can be adjusted according to actual conditions, and the creation is not particularly limited.

The bending rod 10 is connected to a long shaft 20, and the long shaft 20 includes a convex portion 201 that abuts the rotating portion 13, a sleeve 21 attached to the long shaft 20, and the second working Part 22.

The convex portion 201 of the long shaft 20 is inserted into the limiting groove 133 of the rotating portion 13. In order to assist the rotational positioning during use, the convex portion 201 may be provided with at least two positioning grooves, such as a first positioning groove 2011 and a second positioning groove 2012. In this embodiment, when a first virtual line passes through a center point of the first positioning groove 2011, and a second virtual line passes through a center point of the second positioning groove 2012, the first virtual line and the first virtual line The angle between the second imaginary lines is 90°.

In this embodiment, the first sidewall 131 has a first hole 1311, the second sidewall 132 has a second hole 1321, and the protrusion 201 of the long shaft 20 also has a third hole 2010. When the convex portion 201 is completely inserted into the limiting recess 133, the first hole 1311, the second hole 1321, and the third hole 2010 are superposed on each other at the same position (coaxially stacked), and at this time, A rotating pin 14 is inserted into the first hole 1311, the second hole 1321, and the third hole 2010.

In this embodiment, the rotating portion 13 further includes a spring 134 disposed in the limiting recess 133, and a steel ball 135 disposed at one end of the spring 134 and in contact with the spring. In other words, when the long shaft When the bending rod 10 is connected to the bending rod 10 , the spring 134 and the steel ball 135 are respectively disposed between the limiting groove 133 of the rotating portion 13 and the convex portion 201 of the long shaft 20 .

Accordingly, the movable wrench tool of the present invention can be rotated more flexibly, and the user can flex the movable wrench tool into two or three segments according to the needs of the user. When the user bends the movable wrench tool to operate in two stages (L-shaped), in the rotating portion 13, one end of the spring 134 abuts against the limiting groove 133, and the other end is connected with the steel ball 135 contact; for the steel ball 135, is sandwiched between the spring 134 and the second positioning groove 2012 of the convex portion 201, at this time, the extension direction of the long shaft 20 is short The second direction of the shaft portion 12 is the same; when the user bends the movable wrench tool to operate in a three-stage manner (Z-shape), in the rotating portion 13, one end of the spring 134 is pressed against the limit a groove 133, the other end of which is in contact with the steel ball 135; for the steel ball 135, it is sandwiched between the spring 134 and the first positioning groove 2011 of the convex portion 201, at this time, the length The direction in which the shaft 20 extends is the same as the first direction of the first working portion 11, and its appearance is as shown in FIG.

『Fig. 4A』 to 『4C』 are schematic diagrams of the implementation of the movable wrench tool of the present invention. FIG. 4A is a two-stage view (L-shaped) of the movable wrench tool of the second embodiment. After the first working portion 11 is engaged with a screw, the user holds and rotates the long shaft 20 The screw can be easily tightened; FIG. 4B is a three-stage view (Z-shaped) of the movable wrench tool of the second embodiment. First, the movable wrench tool is rotated into a three-stage state through the rotating portion ( Z type), after the first working portion 11 is engaged with a screw, the user holds and rotates the long shaft 20, and shakes quickly to achieve the purpose of quickly tightening the screw. FIG. 4C is another aspect of the movable wrench tool of the second embodiment. After the second working portion 22 is engaged with a screw, the user holds and rotates the first working portion 11 The effect of tightening the screw can be achieved.

As described above, the present invention allows the user to change the aspect of the wrench tool to operate in two or three stages by the design of the rotating portion according to requirements, and has at least the following advantages compared with the conventional one:

1. The design of the rotating part is quite convenient in operation. The user can change the aspect of the wrench tool according to the requirements, and select two-stage (L-shaped) or three-stage (Z-shaped) to meet various environments. Demand, in order to save labor and quickly achieve the purpose of tightening all kinds of fasteners.

2. The wrench tool is designed with two working parts that can be respectively engaged with fasteners of different shapes to increase flexibility and convenience in use.

However, the foregoing is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, the equal changes and modifications made by the scope of the new patent application are covered by the scope of the new patent.
