The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings.

The following examples are used in conjunction with the drawings to illustrate the creation in detail:

As shown in the first to fourth figures, the present invention is a hand tool having a compression shrapnel, comprising: a handle portion 10 and a tool assembly 20.

The handle portion 10 has an inner passage 11, a guiding groove 12, a passage opening 13, a wall opening 14 and a pair of flexible stops 15; the inner passage 11 has two ends, one end is The passage opening 13 has a closed end at the other end. The guiding groove 12 communicates with the internal passage 11 and is parallel to the axial direction of the internal passage 11. The pair of flexible stops 15 are deformable and can be restored.

The tool assembly 20 is disposed in the internal passage 11 of the handle portion 10 and has a tool bar 21, a tool bar pivot joint 22, an outer fixing piece 23, a compression spring piece 24, and a pivot shaft member 25. And a fixing element 26.

One end of the tool bar 21 is provided with a working portion 211, and the other end is the tool bar pivot joint 22.

The tool bar pivot joint 22 has a first pressing surface 221, a second pressing surface 222 and a bump 223.

The outer fixing piece 23 has a first end portion 231 and a second end portion 232. The first end portion 231 of the outer fixing piece 23 is provided with a first hole 233, and the second end portion of the outer fixing piece 23 The 232 is provided with a second hole 234.

The pressing elastic piece 24 has a fixing hole 241, a spring piece portion 242 and a protruding guiding portion 243, and the protruding guiding portion 243 is caught in the guiding groove 12.

The pivoting shaft member 25 is disposed on the tool post pivot joint 22 and the pair of first holes 233 to pivotally connect the outer fixing piece 23 to the tool bar pivot joint 22 .

The fixing member 26 is configured to fix the second hole 234 of the outer fixing piece 23 and the fixing hole 241 of the pressing elastic piece 24, and fix the outer fixing piece 23 and the pressing elastic piece 24 integrally.

Thereby, the tool bar 21 and the outer fixing piece 23 can be switched between a linear relationship and a vertical relationship; when in the linear relationship, the pressing elastic piece 24 is pressed against the tool bar pivot joint 22 a pressing surface 221 and maintaining a linear relationship between the tool bar 21 and the outer fixing piece 23 is not loose; and, in the vertical relationship, the pressing elastic piece 24 is pressed against the second pressing of the tool bar pivot joint 22 The surface 222 and the vertical relationship between the tool bar 21 and the outer fixing piece 23 are not loose.

In more detail, the grip portion 10 is made of a material that can be deformed by an external force, such as rubber. The inner passage 11 is designed such that its inner diameter is substantially the same as the outer diameter of the tool assembly or slightly smaller than the outer diameter of the tool assembly. That is to say, the tool assembly 20 is assembled with the protruding guiding portion 243 to align the guiding groove 12, and the tool assembly 20 is forced by the deformable property of the material of the handle portion 10 itself. Plugged into the internal passage 11.

Regarding the configuration of the grip portion 10, please refer to Figs. 5A to F.

As shown in the fifth through fifth F, the wall opening 14 has a narrow section 141 and an open section 142 which corresponds to the flexible stop 15, and the elongated section 141 The width is less than the outer diameter of the tool bar 21, and the width of the opening is substantially equal to the outer diameter of the tool bar 21. When the relationship between the tool bar 21 and the outer fixing piece 23 is switched to the vertical relationship by the linear relationship, the tool bar 21 first passes through the elongated section 141, and due to the outer diameter of the tool bar 21 Greater than the width of the elongated section 141 forces the pair of flexures 15 to deform and is ultimately located in the open section 142 through the elongated section 141.

As shown in the sixth figure, it changes the appearance of the linear relationship and the vertical relationship of the tool bar 21 and the external fixing piece 23; as can be seen from the sixth figure, the creation only needs to directly rotate the working rod 21 It is switched to a linear relationship or a vertical relationship according to different needs (the angle of view of the sixth figure, the wall opening 14 is downward).

As shown in FIG. 7A, when the tool bar 21 and the outer fixing piece 23 are in a linear relationship, the pressing elastic piece 24 is pressed against the first pressing surface 221 of the tool bar pivot joint 22, so that the tool bar 21 and the tool bar 21 are The outer fixing piece 23 is kept in a straight line relationship without being loosened.

As shown in FIG. 7B, in the process of switching the tool bar 21 and the outer fixing piece 23 from a linear relationship to a vertical relationship, the tool bar 21 rotated causes the bump 223 to abut against the pressing elastic piece. The shrapnel portion 242 of 24 is slightly deformed by a predetermined angle θ.

As shown in FIG. C, when the bump 223 slides over the elastic piece portion 242 to rotate the tool bar 21 to form a perpendicular relationship with the outer fixing piece 23, the elastic piece portion 242 of the compression elastic piece 24 returns to the The deformed state is pressed against the second pressing surface 222 of the tool bar pivot joint 22 so that the vertical relationship between the tool bar 21 and the outer fixing piece 23 is not loose.

Of course, if the tool bar 21 and the outer fixing piece 23 are switched from a vertical relationship to a linear relationship, the sequence of the operation flow is the seventh to seventh A drawings.

In design, the elastic portion 242 of the compression elastic piece 24 has a strong pressing force, and therefore, the elastic piece portion 242 can press the first pressing surface 221 with a strong pressing force regardless of a linear relationship or a vertical relationship. The second pressing surface 222 makes the tool bar 21 relatively stable and difficult to loosen in positioning; of course, the greater the pressing force of the elastic piece portion 242, the greater the force required to rotate the tool bar 21.

In addition, since the shrapnel portion 242 of the compression elastic piece 24 of the present invention has a strong pressing force, the operation can be performed in a straight line relationship or a vertical relationship, so that the user can operate. Apply more torque when (eg, disassemble or lock a screw).

In summary, the advantages and effects of this creation can be summarized as:

[1] can be switched directly. When the conventional switching hand tool is switched between the vertical relationship and the linear relationship, the pressing of the switching button is required to release the fixing, thereby switching the vertical relationship and the linear relationship, which is quite inconvenient in operation; By rotating the working rod 21, the linear relationship and the vertical relationship can be switched, which is quite simple and convenient in operation.

[2] Positioning and fastening are not easy to loosen. The traditional switch hand tool uses the switch button to achieve the switch fixing and unfixing. Such a design is often difficult to achieve strong fixing, and has problems such as poor positioning and easy looseness in use; and the compression shrapnel 24 of the present invention is extremely strong. The pressing force can make the tool bar 21 be fastened and not easy to loose, and effectively avoid the problem of looseness during operation.

The above is only a detailed description of the present invention by way of a preferred embodiment, and any modifications and variations of the embodiments are possible without departing from the spirit and scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and proposes a new type of patent application.
