Abstract
The utility model relates to an improved hand-held electric slotting cutter, which comprises a main body and a machine head, wherein the top portion of the machine head is provided with a dust cap, and two saw blades are arranged on the machine head. The improved hand-held electric slotting cutter is characterized in that either of the two saw blades is fixed on a rotary shaft, the end portion of the rotary shaft is fixed with a detachable extended drive shaft, a plurality of distance sleeves are sleeved on the extended drive shaft, and the other saw blade is fixed on the extension drive shaft. The improved hand-held electric slotting cutter has the advantages of wide application scope, convenient operation, high efficiency and multiple functions.
Description
Technical field
The utility model relates to a kind of equipment of the cutting that is used to slot, and specifically, it is wide to relate to a kind of scope of application, the hand-hold electric grooving cutting machine of high-efficiency multifunctional.
Background technology
The saw blade of existing hand-hold electric grooving cutting machine is monolithic mostly, the not random flexibility of tool of inefficiency, groove width.Recently the hand-hold electric grooving cutting machine that two saw blades occurred, for example Chinese utility model patent publication number are that CN201092094Y discloses a kind of like this hand-hold electric grooving cutting machine.But two saw blades of this hand-hold electric grooving cutting machine are to be fixed on the power transmission shaft, and usability is more single, saw blade dismounting difficulty, and operating efficiency can not get significantly improving.Dust cover is located at the head top in addition, also will change dust cover after removing a saw blade, operation inconvenience.Particularly when cutting machine was used for the body of wall turning, because the power transmission shaft of lengthening is arranged, its use was then more restricted.Therefore how overcoming above difficulty, is that prior art has problem to be solved.
The utility model content
The purpose of this utility model provides that a kind of scope of application is wide, easy to operate, the hand-hold electric grooving cutting machine of high-efficiency multifunctional.
The technical solution adopted in the utility model is: a kind of improved hand-hold electric grooving cutting machine, comprise fuselage and head, described head top is provided with dust cover, described head is provided with two saw blades, a saw blade in described two saw blades is fixed on the power transmission shaft, described power transmission shaft end is fixed with dismountable lengthening power transmission shaft, is socketed with a plurality of distance covers on the described lengthening power transmission shaft, and described second saw blade is fixed on the lengthening power transmission shaft.
Further, described lengthening power transmission shaft is fixedlyed connected with screw thread with the power transmission shaft end.
Further, the distance between described second saw blade and first saw blade is determined by the number of adjustable range cover.
Further, be provided with chute between described dust cover and the head top, described chute is fixedly connected on the fuselage cover.
Because two saw blades are installed in respectively on power transmission shaft and the lengthening power transmission shaft, and the lengthening power transmission shaft is connected on the power transmission shaft by jam nut, dismounting easily, and two saw blade segregations are convenient, so not only improve the scope of application of this hand-hold electric grooving cutting machine, and improved operating efficiency.
Be provided with a plurality of distance covers between two saw blades, the number of adjustable range cover can be controlled the distance of two saw blades, thereby has realized the randomness and the multifunctionality that has improved this hand-hold electric grooving cutting machine of groove width.
Be provided with chute between dust cover and head, chute is fixedly connected on the fuselage, makes the dust cover conveniently moving like this, has guaranteed that after unloading next saw blade this hand-hold electric grooving cutting machine still can operate as normal, has guaranteed the scope of application.
Advantage of the present utility model: the scope of application is wide, and is easy to operate, high-efficiency multifunctional.

The specific embodiment
As shown in Figure 1, 2, a kind of improved hand-hold electric grooving cutting machine, comprise fuselage and head, described head top is provided with dust cover 1, described head is provided with two saw blades 2, and a saw blade in described two saw blades 2 is fixed on the power transmission shaft 3, and described power transmission shaft 3 ends are fixed with dismountable lengthening power transmission shaft 4, be socketed with a plurality of distance covers 5 on the described lengthening power transmission shaft, described second saw blade is fixed on the end of lengthening power transmission shaft 4 by nut 7.Described lengthening power transmission shaft 4 is fixedlyed connected with screw thread 6 with power transmission shaft 5 ends.Distance between described second saw blade and first saw blade is determined by the number of adjustable range cover 5.Be provided with chute 8 between described dust cover 1 and fuselage cover 9 tops, described chute 8 is fixedly connected on the fuselage cover 9.
The utility model is running like this: open handle place switch, motor energising in the fuselage is rotated, motor drives last group of meshing gear by rotating shaft and rotates, under the drive of last group of meshing gear, back group gear rotates, the rotation of back group gear drives power transmission shaft 3 and rotates, and the rotation of power transmission shaft 3 drives the high speed rotating of saw blade 2, and the high speed rotating of saw blade 2 is finished fluting and cutting process.In the fluting cutting process, can regulate out distance between two saw blades 2 by the number of suitable adjustable range cover 5, thus determine the width between slotting.When only needing under the situation of a saw blade job, can dismantle lengthening turning cylinder 4, by nut 7 firmly remaining saw blades, suitably regulate slidably dust cover 1 again, so just can finish the operate as normal of a saw blade.
Claims (4)
