Detailed Description

The following detailed description of the preferred embodiments of the present invention is provided to enable those skilled in the art to more easily understand the advantages and features of the present invention, and to make more clear and definite definitions of the scope of the present invention.

The utility model relates to a combination soldering lug shaping sword, as shown in fig. 1 with the combination of fig. 2-7, including handle of a knife 1 and tool bit 2.

The cutter handle 1 extends towards one side of the cutter head 2 and is provided with a cutter bar 3 connected with the cutter head 2. The cutter arbor 3 is the cylindrical structure setting, the rotation regulation of being convenient for. The cutter bar is characterized in that one side of the end part of the cutter bar 3 is provided with a cross-shaped fixture block 4 of an integrated structure, and two ends of a long edge of the cross-shaped fixture block 4 are respectively arranged on the end surface of the cutter bar 3 in a protruding mode so as to be convenient for later-stage rotation adjustment and fixation.

2 middle parts of tool bit run through and are provided with mounting groove 5 and the setting of closely laminating of guide arm, guarantee the use precision of handle of a knife and tool bit and the stability in use in later stage. The cutter arbor 3 is inserted in mounting groove 5 by the front end of cutting edge 7 one side of tool bit 2, and special design processing is carried out according to the product needs to this structure, just cutting edge 7 is soldering lug form welding on tool bit 2, can effectively practice thrift the cost. And the two opposite sides in the mounting groove 5 are respectively provided with a sliding groove 6 for the movement of the long edge of the cross-shaped fixture block 4. The limiting groove 8 communicated with the sliding groove 6 in the clockwise direction is further annularly arranged at the edge of the mounting groove 5 at the tail end of the cutter head 2, after the long guide rod is inserted into the mounting groove 5, the long edge of the cross-shaped fixture block penetrates through the sliding groove, and the long edge of the cross-shaped fixture block 4 is rotated into the limiting groove 8 by rotating the cutter handle, so that the rotary positioning of the cutter handle 1 and the cutter head 2 is achieved.

During the specific use, insert the cutter arbor from the bolt hole left side earlier, the tool bit gets into from the right side, with the cutter arbor assembly, carries out clockwise rotation locking, and it is more and more firm to make the cutter assembly with the help of the power of cutter processing clockwise rotation, the tool bit phenomenon that drops can not appear in the course of working, and whole novel in design is simple and convenient, helps the customer to solve the difficult point that traditional whole cutter can't satisfy processing. Secondly, because the aperture of the product is close to D50, the cutting edge (blade carbide, base 42 CRMO) is welded on the cutter head in a welding piece mode, so that the cost is saved for customers.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can be covered within the protection scope of the present invention without the changes or substitutions thought by the inventive work within the technical scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
