Abstract
The utility model discloses a dual blade cutting machine comprising a machine body and a machine head which are connected through a center cover, wherein the machine head comprises a head shell, a transmission mechanism, an inner blade, an outer blade and a protective cover; the transmission mechanism comprises a power gear shaft, a first gear, a second gear, a flange and an output shaft; the first gear and the second gear are sheathed on the output shaft and meshed with the power gear shaft respectively; the flange is sheathed on the output shaft and fixedly connected with a front cover of the head shell; the first gear is provided with an internal thread; the tail end of the flange is correspondingly provided with an external thread matched with the internal thread; and the tail end of the flange is arranged in the first gear and fixedly connected with the first gear through the threads. For the dual blade cutting machine, the first gear is provided with the internal thread, the tail end of the flange is correspondingly provided with the external thread, and the tail end of the flange is arranged in the first gear and fixedly connected with the first gear through the threads, therefore, due to the threaded connection mode, the assembly length is shortened, the jump in the rotating process is small and the running is more stable and safer.
Description
(1) technical field
The utility model relates to cutting machine, relates in particular to cutter with double saw bits.
(2) background technology
Cutter with double saw bits is a kind of special electric tool, owing to adopt two saw blades, can improve cutting efficiency, noise-decreasing and vibration greatly.Existing cutter with double saw bits includes head capsule, transmission mechanism, first gear, second gear, flange, interior saw blade, outer saw blade etc., first gear is provided with external screw thread, described flange tail end correspondence is provided with the internal thread that matches, and described first gear parts is built in the described flange, and is affixed by screw thread with flange, the thread connecting mode of this structure, need part long, assembling back axiality is bad, has in the rotary course and beats, stability in use is poor, and is dangerous.
(3) summary of the invention
In order to solve the shortcoming that existing cutter with double saw bits exists, the utility model provides a kind of novel cutter with double saw bits, by being threaded in built-in first gear of flange tail end, has solved the problem of stability in use difference, has improved safety in utilization.
For this reason, the utility model is taked following technical scheme:
A kind of cutter with double saw bits, comprise fuselage, head, described fuselage is connected by middle cover with head, described head includes head capsule, transmission mechanism, interior saw blade, outer saw blade and protective cover, described transmission mechanism includes power tooth axle, first gear, second gear, flange and output shaft, described first gear and second geared sleeve are connected on the output shaft, mesh with power tooth axle respectively, flange is enclosed within on the output shaft, affixed with the protecgulum of head capsule, described first gear is provided with internal thread, and described flange tail end correspondence is provided with the external screw thread that matches, described flange tail end is built in described first gear, and is affixed by screw thread with first gear.
Described flange is fixed on the protecgulum by a bearing.
Employing the utlity model has following advantage: 1, establish internal thread on first gear, flange tail end correspondence is established external screw thread, the flange tail end is built in described first gear, affixed with first gear by screw thread, adopt this thread connecting mode, the assembling contraction in length, it is little to beat in the rotary course, operates more stable, safety; 2, simple in structure, cost of manufacture is low, result of use good.
