[0027] The drilling part comprises a limiting part and a drill bit, the limiting part comprises a supporting rod 106 mounted on the box 101 and a limiting frame 107 clamped on the supporting rod 106, and a regular polygon through hole is formed in the limiting frame 107; the drill bit comprises a drill bit rod 108, the drill bit rod 108 is provided with a hexagonal connecting shaft 113, a limiting block 115 and a cutting edge 116, the hexagonal connecting shaft 113 is in driving connection with the power transmission member, the limiting block 115 is matched with the regular polygon through hole of the limiting frame 107, and the cutting edge 116 is used for drilling a hole in wood, and the blade profile of the cutting edge 116 is coincided with the intersection point of two surfaces of the limiting block 115.

[0028] When it is needed to drill a hole in wood, the staff starts the motor 104 while holding the handle 102 with both hands, so that the cutting edge 116 is aligned with the position of the wood to be drilled, the power of the motor 104 reaches the drill bit rod 108 through the power transmission member, so as to drive the cutting edge 116 to rotate, and since the limiting block 115 is limited by the regular polygon through hole on the limiting frame 107 when rotating, the cutting edge 116 will generate a profile corresponding to the regular polygon through hole when rotating on the wood, so as to drill a hole in the wood, and the shape of the hole is basically the same as that of the regular polygon through hole. In the embodiment, the number of edges of the regular polygon through hole is 4, at this time, the cross-sectional shape of the limiting block 115 is approximately a Reuleaux triangle, that is, the shape of the hole drilled in the wood is a square hole, which is suitable for furniture splicing, riveting and other processes.

[0029] If a triangular hole is needed, the number of edges of the regular polygon through hole is 3, and the shape of the limiting block 115 is changed to adapt to it; if an internal hexagonal hole is needed, the number of edges of the regular polygon through hole is 6, and the internal pushing can be performed accordingly. In the actual operation process, the limiting frame 107 is used in combination with the drill bit rod 108, and has multiple specifications; the staff can install a limiting frame 107 and a drill bit rod 108 of a certain specification on the supporting rod 106 as needed; the clamping type connection makes it more convenient to replace.

[0030] Through the above setting, the hole drilled in the wood is not limited to a circular hole, but can be a polygonal hole, and diversified design is realized; in the furniture manufacturing splicing and riveting process, the hole is formed in one time, without the need of first drilling a circular hole and then trimming the shape, so that the processing efficiency is greatly improved.

The second transmission member 111 is slidably connected with the first transmission member 109 and the third transmission member 110, respectively, to realize eccentric power output of the third transmission member 110.

[0033] The motor 104 transmits power to the first transmission member 109. The first transmission member 109 drives the second transmission member 111, and the second transmission member 111 drives the third transmission member 110 to transmit power to the hexagonal connecting shaft 113. When the hexagonal connecting shaft 113 deviates from the shaft center of the motor 104, the third transmission member 110 slides relative to the second transmission member 111, and the second transmission member 111 slides relative to the first transmission member 109 to realize displacement compensation. In a certain range, the motor 104 can always transmit power to the hexagonal connecting shaft 113 through the power transmission member regardless of the deviation of the hexagonal connecting shaft 113.

[0037] When the hexagonal connecting shaft 113 needs to be connected with the third transmission member 110, the relative angle between the hexagonal connecting shaft 113 and the third transmission member 110 is first adjusted. Then, the hexagonal connecting shaft 113 is inserted into the third transmission member 110, and the screw 114 is twisted to make the screw 114 retract along the radial direction of the third transmission member 110. At this time, the screw 114 is inserted into the limiting hole of the hexagonal connecting shaft 113, so that the hexagonal connecting shaft 113 and the third transmission member 110 cannot be separated.
