The drilling tool 10 can be an electric drill or a pneumatic drill. The tool body 110 further has a sawing side 112 and a cutting side 113. The tool body 110 is provided with a circumferential conversion reciprocating linear motion mechanism 150. The circumferential conversion reciprocating linear motion mechanism 150 converts the circumferential rotational motion of the rotor joint 111 into a reciprocating linear motion. For example, the rotor joint 111 can be coupled to an eccentric cylinder that is passed through the circumferential conversion reciprocating linear motion mechanism 150. One of the interlocking slots 151 (as shown in FIG. 4) is at an appropriate limit, so that the rotation of the rotor joint 111 can drive the circumferentially-converted linear motion mechanism 150 to reciprocate linear motion. The circumferential conversion reciprocating linear motion mechanism 150 is in its The two opposite directions of the complex motion correspond to the sawing side 112 and the cutting side 113. The circumferential conversion reciprocating linear motion mechanism 150 is mounted on the sawing side 112 with a saw blade 160. The circumferential conversion reciprocating linear motion mechanism 150 is The cutting side 113 is fitted with a cutting blade 170.

In the first and second figures, the handle 140 is selectively mounted on the cutting blade holder 130 such that the cutting portion of the cutting blade 170 is hidden in the handle 140, and the sawing portion of the saw blade 160 is exposed, which is more The use sawing tool 100 is embodied in an automatic sawing assembly state. When the drilling tool 10 is joined to the rotor joint 111, an "automatic sawing" operation can be performed (as shown in Fig. 5). In FIGS. 3 and 4, the handle 140 is selectively mounted to the proximal L-shaped sawing bracket 120 such that the sawing portion of the saw blade 160 is hidden in the handle 140, and the cutting portion of the cutting blade 170 is exposed. The multi-purpose sawing tool 100 is in an automatic cutting state. When the drilling tool 10 is joined to the rotor joint 111, an "automatic cutting" operation (as shown in Fig. 6) can be performed. The saw blade 160 and the cutting blade 170 are mounted and coupled to the circumferential conversion reciprocating linear motion mechanism 150, which facilitates the reciprocation of the circumferential conversion reciprocating linear motion mechanism 150, whether in the automatic sawing assembly state or the automatic cutting assembly state. The balance of linear motion.

As shown in Figures 2 and 4, the proximal L-shaped sawing bracket 120 has a first A handle joint 121, such as an externally threaded structure; the cutter holder 130 has a second handle joint 131, such as an externally threaded structure; the handle 140 can have a corresponding internal thread configuration. When the handle 140 is mounted to the first handle coupling portion 121, the sawing portion of the saw blade 160 protruding from the near L-shaped sawing bracket 120 is hidden in the handle 140 (as shown in FIG. 3). When the handle 140 is mounted on the second handle coupling portion 131, the cutting portion of the cutting blade 170 exposed to the cutting blade holder 130 can be hidden in the handle 140 (as shown in FIG. 1). Therefore, in the automatic sawing assembly state and the automatic cutting assembly state, it is not necessary to disassemble the cutting blade 170 and the saw blade 160 that are not used.

As shown in FIG. 4, more specifically, the first handle joint portion 121 The proximal L-shaped sawing bracket 120 can be formed as a separate sleeve on a bracket handle connecting rod 180.

The two ends of the reciprocating plate respectively have a saw bar limiting groove 152 and a shank end engaging hole 153 to specifically define the mounting manner of the saw blade 160 and the cutting shank 170. For example, the reciprocating plate may have a plurality of fixing holes 154 on both sides of the blade limiting slot 152. A saw blade fixing member 161 is mounted on the fixing holes 154 to fix the saw blade 160. The saw blade fixing member 161 may be in the form of a block, and the inner end of the saw blade 160 fixed in the pressing and snapping manner is pressed against the blade limiting slot 152. on. Therefore, the saw blade fixing member 161 is attached to one end of the reciprocating plate projecting toward the proximal L-shaped sawing bracket 120. The shape of the shank end engaging hole 153 may correspond to the rod engaging end 172 of the cutting shank 170 (as shown in FIG. 4) to fix the cutting shank 170 and the reciprocating plate.

As shown in FIG. 4, the interlocking slot 151 of the reciprocating plate A length may be less than the length of the proximal L-shaped sawing bracket 120 extending from one of the sawing sides 112 such that the blade holder 161 is movable within the extended space of the proximal L-shaped sawing bracket 120. Therefore, the speed of the "automatic saw" and "automatic cutting" can be judged by the reciprocating linear motion frequency of the saw blade fixing member 161. More specifically, the multi-purpose sawing tool 100 can further include a safety cover 123 that can be mounted to the proximal L-shaped sawing bracket 120 to cover the extended space (as shown in Figures 1 and 3). The material of the safety cover 123 can be a transparent plastic. The mounting of the safety cover 123 prevents the reciprocating linear motion of foreign matter from entering the saw blade fixing member, and also prevents accidental operation damage in the extended space.
