Description
Technical field
The utility model relates to a kind of hand-hold electric grooving instrument, particularly a kind of wall-slotting machine of burying underground for ground and wall pipeline.
Background technology
At present, in office and household upholster process, all need wiring, the laying of water-gas pipeline, TV and the communication line wiring carried out, the general wall-slotting machine that adopts is slotted on ground or wall, because wall-slotting machine fluting efficiency is high, its operating efficiency is even tens times of artificial several times of slotting, and is therefore doubly the user's favorite; But in use have the following disadvantages: existing wall-slotting machine can only be opened straight trough on same metope or ground, between metope and metope, ground and metope corner, exist dead angle to slot owing to being subject to the obstruct of cast-cutting saw slice guard shield, in the time that slotting, corner also needs manual completing, directly the operating efficiency of impact wiring or stringing; For this reason, many manufacturers and knowledgeable people have carried out development, but not yet have so far good product to emerge.
Summary of the invention
The above-mentioned disadvantage existing for overcoming existing wall-slotting machine industry, the purpose of this utility model is a kind of simple and reasonable, easy for operation, safe and reliable, wall-slotting machine without cutting dead angle that corner also can be slotted of exploitation.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises body, head capsule, movable shield, cast-cutting saw slice, head capsule is fixed on body, described cast-cutting saw slice is arranged on head capsule foremost rotationally, and body drives cast-cutting saw slice rotary work by the speed change gear being arranged in head capsule; Head capsule is provided with saw blade and protects groove, and movable shield is arranged on rotationally on head capsule and is covered on cast-cutting saw slice by torsion spring, and the saw blade that movable shield can be accommodated in head capsule protects in groove.
The further scheme of the utility model, described head capsule is provided with flexible lock pin, and movable shield is provided with the lockhole matching with flexible lock pin.
The utility model is scheme further, and described movable shield is provided with positive stop.
The utility model is scheme further, on described head capsule, is fixed with front hand grip.
Adopt after said structure, compared with prior art have the following advantages and effect: the one, because movable shield is arranged on rotationally on head capsule and is covered on cast-cutting saw slice by torsion spring, can reach the object that existing wall-slotting machine is slotted on same metope or ground; The 2nd, when encountering while slotting between metope and metope, ground and metope corner, movable shield can be protected in groove by the saw blade that is accommodated in flexible lock pin and coordinating of lockhole head capsule, make cast-cutting saw slice expose part and reach 270 ° of left and right, reach the function without dead angle cutting, thereby reach the object that also can slot between metope and metope, ground and metope corner, simple to operate, easy to use.
Accompanying drawing explanation
Structural representation when Fig. 1 is the utility model movable shield closure.
Fig. 2 is the structural representation of the utility model movable shield while opening.
Fig. 3 is the fluting schematic diagram of the utility model in the time that movable shield is closed.
Fig. 4 is the corner fluting schematic diagram of the utility model in the time that movable shield is opened.
Wherein 1 movable shield, 2 head capsules, 3 flexible lock pins, 4 front hand grip, 5 bodies, 6 lockholes, 7 positive stops, 8 cast-cutting saw slices, 9 metopes or ground.
The specific embodiment
Shown in Fig. 1 and Fig. 2, for the utility model is without the specific embodiments of the wall-slotting machine at cutting dead angle, it comprises body 5, head capsule 2, movable shield 1, cast-cutting saw slice 8, head capsule 2 is fixed on body 5, cast-cutting saw slice 8 is arranged on head capsule 2 rotationally, and body 5 drives cast-cutting saw slice 8 rotary works by the speed change gear being arranged in head capsule 2; Described head capsule 2 is provided with saw blade and protects groove, and movable shield 1 is arranged on rotationally on head capsule 2 by torsion spring and covers on cast-cutting saw slice 8, and the saw blade that movable shield 1 can be accommodated in head capsule 2 protects in groove.In order to make can to lock between movable shield 1 and head capsule, described head capsule 2 is provided with flexible lock pin 3, and movable shield 1 is provided with the lockhole 6 matching with flexible lock pin 3.Reliable for movable shield 1 is used, described movable shield 1 is provided with positive stop 7.For easy for operation, on described head capsule 2, be fixed with front hand grip 4.
Shown in Fig. 3, the schematic diagram while fluting on same metope or ground 9 for the utility model, movable shield 1 cover cap is on exposed cast-cutting saw slice 8, safe and reliable while guaranteeing operation.
Shown in Fig. 4, the schematic diagram while fluting on metope or ground 9 corners for the utility model, now movable shield 1 be accommodated in head capsule 2 saw blade protect in groove, movable shield 1 does not affect the fluting work of cast-cutting saw slice 8 at corner.
The above; be an embodiment of the present utility model, not the utility model made to any pro forma restriction, do not departing from the technical solution of the utility model basis; simple modification, equivalent variations or the modification done, all fall into protection domain of the present utility model.
