Detailed ways

Please refer to Fig. 1 and Fig. 2, the structure of the selected embodiment of the present invention is shown in the figure.

The present invention is a single-head pivoting tool with a detachable head, which includes a driving tool body 1, one end of the body 1 has a grip portion 11 for the hand to hold, and the body 1 The other end has a pivoting portion 12 for pivoting with a swing assembly 2. In this embodiment, the pivoting portion 12 has a slot 121, and two sides adjacent to the slot 121 have a through hole respectively. 122 communicates with the slot 121 . In addition, the swing assembly 2 has a protruding portion 25 corresponding to the aforementioned slot 121, and the protruding portion 25 has a through hole 251. The protruding portion 25 is inserted into the slot 121, so that the protruding portion 25 The through holes 251 and the through holes 22 of the pivot joint 12 are located on the same axis, and then a fixing bolt 26 is inserted into the through holes 22 and the through holes 251, so that the swing assembly 2 can be pivotally connected to the body 1, and can be Match a spring washer 252 and place it adjacent to the pivotal portion 12 and the protruding portion 25 to support the gap between the through hole 22 and the through hole 251, and the swing assembly 2 can be perpendicular to the pivotal portion 12 The operating direction of the workpiece wrenching assembly 3 swings 180°.

The end of the swing assembly 2 away from the protrusion 25 is provided with an engaging portion 21 . A groove 22 is formed inside. In addition, a through hole 23 is provided on the engaging portion 21 to communicate with the groove 22, and a concave hole is provided on the side of the inner edge of the groove 22 communicating with the through hole 23. Hole 24, the recess 24 is away from the protrusion 2 from the groove 22

The end surface 211 of 5 is connected to each other. In this embodiment, the cavity 24 is an inclined section tapered inwardly from the end surface 211 toward the bottom of the groove 22 .

In addition, a workpiece wrenching assembly 3 for wrenching the workpiece (in this embodiment, the workpiece wrenching assembly 3 is an open-end wrench) has an engaging section engaged with the engaging portion 21 of the swing assembly 2 31 . In this embodiment, the engaging section 31 is convex relative to the groove 22 of the swing assembly 2 . The engaging section 31 has a blind hole 32 on one side corresponding to the through hole 23 of the engaging portion 21, and a blocking unit 33 is arranged in the blind hole 32, and the blocking unit 33 is formed by an elastic component 34 (in this embodiment is a spring) and a positioning component 35 (a steel ball in this embodiment); under normal conditions, the positioning component 35 protrudes from the surface of the engaging section 31 supported by the elastic component 34 .

When in use, the way to engage the swing assembly 2 with the workpiece pulling assembly 3 is to directly insert the engaging section 31 of the workpiece pulling assembly 3 into the swing assembly 2 on the outer side where the positioning assembly 35 protrudes. In the groove 22 of the engaging part 21 and corresponding to the side with the recess 24, because the recess 24 has a guiding function as a tapered inclined section from the outside to the bottom of the groove 22, so the When the convex engaging section 31 is inserted into the groove 22 of the engaging portion 21 , the positioning component 35 is guided by the recess 24 to press the positioning component 35 into the blind hole 32 . And when the through hole 23 of the engaging portion 21 is at the same axial position as the blind hole 32 of the engaging section 31 of the workpiece pulling assembly 3, the positioning assembly 35 is protruded from the elastic assembly 33 by the support of the elastic assembly 33. The surface of the engaging section 31 is locked against the through hole 23 of the swing assembly 2 , so that the workpiece pulling assembly 3 can be clamped and fixed in the swing assembly 2 .

However, the most important thing is that when you want to disassemble the workpiece pulling assembly 3 to adapt to different types of workpieces, you only need to press the positioning assembly 35, and the positioning assembly 35 is separated from the swinging assembly by compressing the elastic assembly 34 2 through hole 23, and the workpiece pulling assembly 3 is extracted to separate from the swinging assembly 2, and then another workpiece pulling assembly 3 is replaced. A tool that moves another workpiece.

In summary, the present invention does have the following advantages:

1. It can be applied to different workpiece types and specifications.

2. Easy and fast assembly and disassembly.

3. The main body of the driving tool is the same body, and there is no need to purchase other driving tool bodies, so it does not take up space in storage.

In addition, please refer to FIG. 3 , which is the second embodiment of the present invention, and the operation method and operation principle of the tool are the same as those of the above embodiment, and will not be repeated here. The difference is that the engagement structure between the swing assembly 4 and the workpiece 5 is changed, wherein, the engagement portion 41 of the swing assembly 4 is convex, and on one side of the engagement portion 41 A blind hole 42 is provided, and a blocking unit 43 is also provided in the blind hole 42, and the blocking unit 43 is also composed of an elastic component 44 (still a spring in this embodiment) and a positioning component 45 (in this embodiment In the example, it is still a steel ball), and in a normal state, the positioning component 45 will be pressed by the elastic component 44 and slightly protrude on the surface of the engaging part 41; The engagement section 51 forms a groove 52 from the end surface 511 of the engagement section 41 adjacent to the swing assembly 4 for the aforementioned engagement section 41 to fit in, and defines a through hole 53 on the engagement section 51, To communicate with the groove 52 .

Please refer to Fig. 4 again, it is the third embodiment of the present invention, wherein, the above-mentioned positioning component can be replaced by a convex positioning pin 46, and this positioning pin 46 can also be achieved by the support of the elastic component 44. The aforementioned carding effect.

Please refer to FIG. 5 again, which is a fourth embodiment of the present invention, wherein the workpiece wrench assembly 3 can be an adjustable wrench, so it can also have the same effect.

Please refer to FIG. 6 again, which is a fifth embodiment of the present invention, wherein, the workpiece wrenching assembly 3 can be a one-way ratchet wrench, so it can also have the same effect.

Of course, there are still many examples of the invention in which only the details vary. Please refer to Fig. 7 to Fig. 9, which are the sixth embodiment to the eighth embodiment of the present invention, wherein the workpiece wrench assembly 3 can be selected as a two-way ratchet wrench, a positioning socket wrench or a ring wrench, so, It can also have the same effects as the foregoing embodiments.
