Taiwanese Utility Model Patent No. 095203952 discloses a universal oblique hole drilling die clamp for carpentry. Taiwanese Utility Model Patent No. 095203264 discloses an oblique hole drilling die for carpentry. In the conventional technique, an attachment end face on one side of a die block is attached to a timber to be processed to locate the timber. Then an external rod-shaped drill bit is extended into a guide passage of the die block. The axis of the guide passage is inclined from the attachment end face, whereby under the guide of the guide passage, the drill bit can drill an oblique hole on the timber, which is coaxial with the guide passage in accordance with the carpentry requirements.

In order to facilitate the carpentry work, the conventional technique further provides a horizontal or vertical die block guide structure for adjusting the attachment position of the die block relative to the timber.

In this case, the drifling angular position of the drill bit on the timber can be changed in accordance with different sizes of the timbers or different drilling requirements. Accordingly, the oblique hole drilling However, none of the above Patents provides a practical technique for a carpenter to adjust the drilling angle. As a result, when the carpenter needs to drill an oblique hole with a different inclination on a timber, it is necessary to use different die blocks to complete the work. This is because the angle contained between the axis of the guide passage and the attachment end face is fixed. This shortcoming needs to be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to Figs. 1 to 5. According to a preferred embodiment, the oblique hole drilling die seat 10 for the carpentry of the present invention includes a seat member 20, a die section 30 and a locating section 40.

The seat member 20 has a base section 21 in the form of a substantially rectangular board, a first end section 22 and a second end section 23. The first and second end sections 22, 23 are spaced from each other and respectively disposed at two lengthwise ends of the base section 21. A lateral edge of the first end section 22, which lateral edge faces the second end section 23, has a plane locating face 24. A timber to be drilled can be clamped between the first and second end sections 22, 23 with one face of the timber abutting against the locating face 24. Under such circumstance, the timber is located to be drilled and processed.

To speak more specifically, the first end section 22 has a first sideboard 221 and a second sideboard 222 in parallel to each other. The first and second sideboards 221, 222 are spaced from each other and disposed at a lengthwise end of the base section 21 with board faces in parallel to a length of the base section 21. End faces of the first and second sideboards 221, 222, which end faces face the second end section 22 form the locating face 24.

The second end section 23 has an end board 231 perpendicularly fixedly disposed at the other lengthwise end of the base section 21. A threaded rod 232 is screwed through the end board 231 with an axis of the threaded rod 232 in parallel to the length of the base section. A press board 233 is fitted on one end of the threaded rod 232, which end is positioned between the end board 231 and the first end section 22. Accordingly, with one face of a timber to be drilled abutting against the locating face 24, the threaded rod 232 can be screwed to make the press board 233 press the other face of the timber so as to locate the timber on the seat member 20 to facilitate the drilling operation.

The die section 30 is detachably pivotally disposed at the first end section 22 and swingable between a first position and a second position.

Structurally, the die section 30 has a die body 31 in the form of a substantially wedged block. A thinner end of the wedged block is defined as a bottom end. The bottom end is clamped between the first and second sideboards 221, 222. Two lateral faces of the die body 31 are respectively pivotal ly connected to the first and second sideboards 221, 222 via two bolts. Accordingly, the die body 31 can be pivotally swung around the bolts between the first and second positions. A pair of oblique guide passages 32 downward extends through the die body 31 from a top end of the die body 31 to a face 311 of the die body 31, which face faces the second end section 23, to form a pair of guide passage outlets 321 respectively.

The locating section 40 is used to restrict the die section 30 from pivotally swinging and locate the die section 30 in a certain working position. The locating section 40 includes a pair of first through holes 41, a pair of second through holes 42 and a pair of third through holes 43 formed through upper ends of the first and second sideboards 221, 222 respectively. The pair of third through holes 43 is positioned between the pair of first through holes 41 and the pair of second through holes 42. A pair of connection holes 44 is respectively formed on two lateral faces of the die body 31, which lateral faces are adjacent to the first and second sideboards 221, 222. The die section 30 can be swung to change its angular position so as to coaxially align the pair of connection holes 44 with any of the pair of first through holes 41, the pair of second through holes 42 and the pair of third through holes 43.

The bodies of a pair of locaUrig bolts 45 are passed through any of the pair of first through holes 41, the pair of second through holes 42 and the pair of third through holes 43 and screwed into the pair of connection holes 44 so as to fix the die body 31 between the first and second sideboards 221, 222 in the working position.

To speak more specifically, when the die section 30 is positioned in the first position, the connection holes 44 are coaxially aligned with the pair of first through holes 41. When the die section 30 is positioned in the second position, the connection holes 44 are coaxially aligned with the pair of second through holes 42. When the die section 30 is positioned in a third position, the connection holes 44 are coaxially aligned with the pair of third through holes 43. Accordingly, according to an actually required drilling angle, by means of the locating section 40, the angular position of the die section 30 can be changed to locate the die section in a working position corresponding to any of the first, second and third positions to facilitate the oblique hole drilling operation of a carpentry.

Substantially, the oblique hole drilling die seat 10 for the carpentry of

S

the present invention can be used in three modes as shown in Figs. 3 to 5. When the die section 30 is positioned in a working position corresponding to the first position, the face 311 of the die body 3lis coplanar with the locating face 24. In this case, the guide passage outlets 321 are adjacent to a lateral side of a timber 60 to be drilled.

Accordingly, a rod-shaped drill bit 70 driven by an external power supply can be extended into the corresponding oblique guide passage 32 to drill a desired oblique hole on the timber 60 under the guide of the oblique guide passage 32 as shown in Hg. 3.

When it is necessary to change the angle of the oblique hole in accordance with the practical carpentry requirement, the position of the die section 30 of the oblique hole drilling die seat 10 relative to the seat member 20 can be selectively changed from the first position to the third position or the second position as a proper working position.

Accordingly, the timber 60 can be drilled with an oblique hole of a different inclination.

Moreover, as shown in Hg. 6, the present invention also provides an oblique hole drilling kit 1 for carpentry, which includes the components of the above oblique hole drilling die seat 10 and further includes a pad body 50 in addition to the respective components of the oblique hole drilling die seat 10.

The pad body 50 has a pad block 51. A first base face 52 and a second base face 53 are respectively formed on two adjacent sides of the pad block 51. A first abutment end 54 and a second abutment end 55 are formed on the other two adjacent sides of the pad block 51. The first base face 52 is opposite to the first abutment end 54, while the second base face 53 is opposite to the second abutment end 55.

In addition, the face 311 of the die body 31 is formed with an insertion channel 312 having a shape complementary to that of the first and second abutment ends 54, 55.

Accordingly, the oblique hole drilling kit 1 not only can be used in the modes as shown in Figs0 1 to 5, but also can be used in a mode as shown in Fig. 7, in which only the die section 30 is used to drill an oblique hole. Alternatively, as shown in Figs. 8 and 9, the die section 30 can be co-used with the pad body 50 to drill an oblique hole.

To speak more specifically, as shown in Fig. 7, a carpenter can attach the face 311 of the die body 31 to a timber 60 to be drilled. Then, by means of suitable connection members such as screws, the die section is connected to the timber 60 to be drilled. In this case, the drill bit can be guided by the oblique guide passage 32 to drill an oblique hole on the timber 60.

Alternatively, as shown in Figs. 8 and 9, the carpenter can place the pad body 50 between the die section 30 and the timber 60 to be drilled. In accordance with the practical angle requirement of the oblique hole of the carpentry, the carpenter can selectively attach the first base face 52 or the second base face 53 to the timber 60. Also, the carpenter can insert the first abutment end 54 or the second abutment end 55 into I0 the insertion channel 312. Then, by means of suitable connection members such as screws, the die section 30 is connected to the timber to be drilled. In this case, the drill bit 70 can be guided by the oblique guide passage 32 to drill an oblique hole on the timber 60. The pad body 50 serves to lift one end of the die body 31 so as to change the angle of the oblique guide passage 32 relative to the timber 60 to be drilled. Accordingly, the drill bit 70 can be guided by the oblique guide passage 32 to drill the timber 60 with an oblique hole of a different inclination.

The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
