The purpose of this utility model provides a kind of wire cutting machine tool bit, it is by being provided with the direction rotating mechanism between cutting blade and bent axle, make bent axle parallel, can hand wire cutting machine tool bit and carry out trimming, use convenient with set of blades, reduced labour intensity, increase work efficiency, whole tool tip and cutter head lid good airproof performance, it is little to leak gas, it is better to inhale the line effect, and noise is lower.
The utility model is achieved by the following technical solution: it comprises the jet blade seat, the cutter head lid, bent axle, bearing and set of blades, wherein set of blades comprises cutting blade, cutter stator and compressing tablet, the cutter head lid is installed in the top of tool tip and forms cavity volume between them, the bottom of tool tip is provided with the edge pipe respectively and inhales spool, the crankshaft installed of cover upper bearing (metal) is in the edge pipe, the bent axle top extend into the cavity volume the inside, inhaling spool is communicated with cavity volume, bottom at cavity volume, be provided with direction switching mechanism between cutting blade and bent axle, this direction switching mechanism comprises slide block, centering block and mandrel, slide block set is contained in the outside, top on the bent axle, slide block places the tail end groove the inside of centering block, the centering block middle part is installed on the mandrel, cutting blade, cutter stator is positioned at the side of bent axle and is installed on the side of tool tip, and the top boss of centering block is embedded in the chute of cutting blade.
Above-mentioned described in the cavity volume side, the set of blades afterbody is provided with the oil sealing felt.
Above-mentioned described cutter head lid regulates catch by air quantity and bonnet assembles, and air quantity is regulated catch and is provided with corresponding wire casing.
The utility model compared with prior art has following advantage: 1) make blade turn over certain angle by increasing the direction rotating mechanism, make bent axle parallel, can hand wire cutting machine tool bit and carry out trimming, use convenient with set of blades, reduced labour intensity, increased work efficiency; 2) the suction spool directly is set in tool tip, whole tool tip and cutter head lid good airproof performance, it is little to leak gas, and suction line effect is better, and noise is reduced greatly, and relatively power saving; 3) the oil sealing felt is set between direction rotating mechanism and cutting blade, can prevents that lubricating oil from overflowing; 4) on air quantity adjusting catch, be provided with corresponding wire casing, the easier set of blades that is inhaled into of the end of a thread is sheared.
