Description

Multifunctional saw

Technical field

The utility model relates to a kind of hand held electric tool, and particularly a kind of electric circular saw that can be used as uses, if the circular saw on the head tool spindle is pulled down, changes into grinding tool sheet and rotary handle and can make the multifunctional saw that electric angle grinder uses again.

Background technology

Commercially available electric circular saw is various in style, have desk-top, portable, portable etc., but function singleness, the consumer have to buy various instrument for different demands.

Number of patent application CN02118925.0 " electric circular saw of multi-position fixing auxiliary-handle " only mentions two auxiliary-handle jockeys is set on electric circular saw, auxiliary-handle both can be installed on the main handle, also can be installed on the secure shroud, the operator is adjustable auxiliary-handle position, tired and the damage that when improving the electric circular saw operation operator's wrist is brought reduces balance and validity that torsion and moment of torsion improve saw.

Number of patent application CN200510094730.3 " electric circular saw " is equipped with the saw blade indicating device on fuselage, indicating device moves with respect to fuselage, makes saw blade and work piece cut line accurately align, accurately cut.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of multifunctional saw is provided, both made electric circular saw and used, the machining tool on the transposing head working shaft can be made electric angle grinder again and use a tractor serves several purposes, make full use of, for market provides a kind of new tool easy to use again.

The technical scheme in the invention for solving the above technical problem is: multifunctional saw is by the motor case of band power line, motor bonnet and band lock-button with high low speed switch, tool spindle, the head of boss links into an integrated entity, also fix on the head tool spindle with pressing plate, by being connected with flexible blade guard, limited post, the fixed blade guard of saw blade is fixed on the electric circular saw workpiece that constitutes on the base plate and forms the handle that has auxiliary-handle, described handle is the separate piece that can rotate around motor case outward, described handle is by a left side, right handles and handle cover auxiliary-handle, the integral body that pinching screw is fixed into is gone back the electric angle grinder workpiece that interchangeable is made of the fixed blade guard of being with the grinding tool sheet on the described head tool spindle.

Compared with prior art; advantage of the present utility model is: the grinding tool sheet is the machining tool that uses as electric angle grinder in this multifunctional saw; saw blade and base plate are the machining tools that uses as electric circular saw; this two processing work all is that separate piece can be used separately; just can operate as long as be installed on the head working shaft; dismounting, transposing are convenient, and saw blade, grinding tool sheet all be equipped with protective devices such as fixing, flexible blade guard and fixed blade guard outward, use install, reliable.In addition because of the function difference of electric angle grinder, electric circular saw, the installation site of grinding tool sheet, saw blade is not both vertical each other with working face yet, and the handle of this saw and casing are isolating constructions, handle is the integral body of two semicircles through linking by symmetry, the convertible angle of handle turn 90 degrees around positive and negative the revolving of casing, satisfy the requirement of electric angle grinder, electric circular saw duty respectively, can not influence consumer's operation, make a tractor serves several purposes, make full use of, for market, consumer provide a kind of easy to use, new tool that service efficiency is high.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Be connected with tool spindle 23 in the middle of the boss 24 that one band groove is arranged on the head 5 front end lower surfaces, boss.

Motor case 8, the motor bonnet 9 of band power line, high low speed switch 16, the head 5 usefulness screws, the seam that have lock-button 4, tool spindle 23, boss 24 are fixing in aggregates.

It is trapezoidal location terminal 22 that uniform cross section is arranged on the motor case 8 front edge peripheries, the back stop slot 17 of ring spill is arranged, as shown in Figure 3 on the casing rear end periphery.

The reinforcement that lattice shape projection is arranged on the inner surface of left and right handle 29,25, the upper plane two ends have internal and external stopper are arranged respectively on through hole, screw, the edge, the bottom is that semicircle both sides of the edge have raised line 26, it is trapezoidal detent 28 that uniform cross section is arranged on the raised line of one side, lower limb has hinge hole 27, the sealing of right handles 25 tops, and an opening is arranged at left handle 29 tops, as Fig. 5, shown in Figure 6, the hinge hole of passing on the left and right handle with axle 27 is hinged to one with it.

The main switch 6 of live line is installed on the handle cover 30, handle cover 30 is screwed sealing place in right handles 25, the left and right handle that fuses is coated on the outer surface of motor case 8, raised line 26 on the left and right handle is embedded in the back stop slot 17 on the motor case 8, location terminal 22 on the motor case is embedded in the detent 28 on the left and right handle, and with the screw thread of housing screw 10, auxiliary-handle 3 ends, left and right handle is fixed into handle 7, and handle 7 is fixed on the motor case 8.
