1 is a schematic view showing the appearance of a portable hand tool according to an embodiment of the present invention. 2 is a schematic exploded view of the portable hand tool of FIG. 1. 3 to 6 are schematic cross-sectional views of the portable hand tool of Fig. 1. Referring to FIGS. 1 through 6, the portable hand tool of the present embodiment includes a base 10, at least one tool 20, and at least one locking device 30.

The base 10 includes a first case member 11 and a second case member 12 that connects the first case member 11. A space capable of accommodating the tool 20 is formed between the first case member 11 and the second case member 12.

The tool 20 is pivotally coupled to the base 10 and disposed between the first housing member 11 and the second housing member 12. In this embodiment, the number of the tools 20 is plural, and is divided into a first tool set 201 and a second tool set 202. The first tool set 201 can be pivotally disposed on a first axis A1. At one end of the base 10, the second tool set 202 can be pivotally disposed at the other end of the base 10 about a second axis A2. The two tools 20 of the first tool set 201 respectively abut the first shell member 11 and the second shell member 12, and the two tools 20 of the second tool set 202 respectively abut the first shell member 11 and the second shell member 12. The number of the locking mechanisms 30 is two, and the first tool group 201 and the second tool group 202 are respectively disposed along the first axis A1 and the second axis A2.

The tool 20 includes a drive member 21 and a positioning member 22 that connects the drive member 21. The driving member 21 has a driving end 211 selectively exposed on the base 10, a pivot end 212 opposite to the driving end 211, and at least one engaging groove 213 disposed on a side of the pivot end 212. In this embodiment, the driving end 211 is a hex wrench.

The positioning member 22 has a through hole 221 , at least one positioning groove 222 for communicating the through hole 221 , and at least one engaging portion 223 disposed on one side of the positioning member 22 . The positioning groove 222 extends outward in the radial direction of the through hole 221 by the circumference of the through hole 221. In this embodiment, the number of the positioning slots 222 is four and is worn along The circumferential direction of the holes 221 is 90 degrees apart from each other. As shown in FIG. 3, the through hole 221 and the positioning groove 222 can collectively form a slightly quadrangular cross-sectional shape.

The number of the engaging portions 213 of the driving member 21 and the engaging portions 223 of the positioning member 22 are both two and are engaged with each other. Therefore, the driving member 21 can drive the positioning member 22 to pivot together with respect to the base 10, so that the driving end 211 of the driving member 21 is exposed to the base 10.

The locking mechanism 30 includes a control member 31 and an elastic member 32. The control member 31 is movably disposed through the first housing member 11 and the second housing member 12 of the base 10 and the pivoting end 212 of the driving member 21 of the tool 20 and the through hole 221 of the positioning member 22, and can be locked in the locked position. The transition between the release positions.

The control member 31 has an outer peripheral surface 311, at least one positioning portion 312, a pressing portion 313, a limiting portion 314, and a spacer 315. The positioning portion 312 extends outward from the outer peripheral surface 311 along the radial direction of the control member 31 and is selectively engaged with the positioning groove 222 of the positioning member 22. In the present embodiment, the number of the positioning portions 312 is four and is formed on the top edge, the bottom edge, and the side edges of the outer circumferential surface 311, respectively, and is spaced apart from each other by 90 degrees along the circumferential direction of the outer circumferential surface 311. The limiting portion 314 and the spacer 315 are disposed at an end opposite to the pressing portion 313, and the limiting portion 314 selectively contacts the spacer 315 as the control member 31 moves relative to the base 10 and the tool 20.

The opposite ends of the elastic member 32 abut against the base 10 and the pressing portion 313, respectively. In the present embodiment, the elastic member 32 of one of the two locking mechanisms 30 abuts the first shell member 11 of the base 10, and the elastic member 32 of the other locking mechanism 30 abuts the second shell member 12 of the base 10. The elastic member 32 can be a compression spring.

Since the first tool set 201 and the second tool set 202 in this embodiment and the corresponding locking mechanism 30 respectively have the same operating principle, only the first tool set 201 and its corresponding locking mechanism 30 will be described below.

Referring to FIG. 3 and FIG. 4 , when the control member 31 is in the locked position, the positioning portion 312 is engaged with the positioning slot 222 , and the limiting portion 314 contacts the spacer 315 . The positioning member 22 of the tool 20 is restricted by the positioning portion 312 of the control member 31, so that the driving member 21 of the tool 20 cannot pivot relative to the base 10.

Referring to FIG. 5 and FIG. 6, the user can press the pressing portion 313 of the control member 31 to move the control member 31 along the first axis A1 with respect to the base 10 and the through hole 221 of the positioning member 22. The control member 31 is changed from the locked position to the locked position. Release the position. At this time, the elastic member 32 is compressed between the pressing portion 313 and the first case member 11 , the positioning portion 312 is separated from the positioning groove 222 , and the outer peripheral surface 311 faces the positioning groove 222 . At this point, the positioning member 22 of the tool 20 is not restricted by the positioning portion 312 of the control member 31, so that the driving member 21 of the tool 20 can be pivoted relative to the base 10, so that the driving end 211 of the driving member 21 is exposed to the base 10, Moreover, it is possible to perform a work of rotating a fixing member such as a bolt. When the user no longer presses the pressing portion 313 of the control member 31, the elastic restoring force of the elastic member 32 can drive the control member 31 to return to the locked position from the release position.

In addition, it can be easily understood that the present invention can change the relative angle between the driving member 21 and the base 10 by the positioning slot 222 and the positioning portion 312. In this embodiment, the number of the positioning groove 222 and the positioning portion 312 are four and 90 degrees apart from each other, so that the driving member 21 and the base 10 can be at 0 degrees (as shown in FIG. 3 ) and 90 degrees ( Positioned between 180 degrees and 270 degrees as shown in Figure 6.

In summary, the portable hand tool of the present embodiment enables the tool 20 to be selectively positioned at a plurality of relative angles with respect to the base 10 by the arrangement of the locking mechanism 30, so as to avoid pivoting relative to the base 10 Pendulum, causing inconvenience in use.

The present invention has been disclosed in the above embodiments, but it is not intended to limit the invention, and any one of ordinary skill in the art can be made without departing from the spirit and scope of the invention. There are a few changes and modifications, and the scope of protection of the present invention is defined by the scope of the appended claims.
