Description

Auxiliary sawing device for hand saw

The utility model is that coping saw is relevant, more detailed it, refer to that especially a kind of coping saw assists saw cutting device, it can provide the more accurate clever reviver of the oblique sawing operation of angle.

Press, the use of relevant coping saw in advance, except that know-how personnel of factory such as pincers worker etc. are often used, general housewife waits the non-professionality personnel also often to need to use, therefore before layman's operation, put, the dealer is a kind of auxiliary saw cutting device of development, it ties up to a base body bottom side one or two ends that are pivoted and has the elongate frame of holder, set firmly two straight-bars on the holder as the sheathed location of coping saw and utilize, base moves to change at the elongate frame level angle and leads whole coping saw translation predetermined angular orientation and in addition to the workpiece sawing, though these devices have definite guiding function in independent coping saw operation, but use is not then still applied in vertical mis-cut angle of sawing must make to(for) workpiece, and commonly using auxiliary saw cutting device at present can only operate at dual space, for the manual line of then still must going ahead of the rest of tridimensional angle, and then change with hand-held coping saw, the mat work operator experienced side that holds a sword in one's hand is accomplished, still very difficult to general unskilled personage, so the breakthrough of the auxiliary relevant mis-cut angle of saw cutting device of coping saw is the problem that present industry presses for solution.

The main purpose of the utility model, tying up to provides a kind of coping saw to assist saw cutting device, breaks through the restriction of traditional dual space, can allow the layman also carry out manipulating of vertical mis-cut angle easily and accurately.

It includes a base body the auxiliary saw cutting device of a kind of coping saw of the utility model, its bottom and for the angle pivot translation locate mode microscler framework that is pivoted, this microscler framework two sides and be provided with a holder, this holder top also uprightly sets firmly two slide bars, establishes for a coping saw positioning sleeve; The top of this base body then outwards is extended into the scallop section of one 90 degree angles with this microscler framework axle pivot place; Its feature tie up in:

Two ends of this microscler framework and radially enlarge the axle sleeve extend into a circle respectively, this axle sleeve central authorities and be arranged with the recess of a desired depth, the top of this recess also outwards enlarges and extends into an opening, its external diameter circumference and be arranged with plural locating hole in staggered mode; This holder system is a C shape collar that is sleeved on this axle sleeve external diameter, its internal diameter system is corresponding with footpath outside this axle sleeve and make the axle center of the two and this coping saw sawing bottom line be a straight line, to do the sawing use that axle closes pivoting angle, the locating hole of the relative axle sleeve of its external diameter also is concaved with plural dowel hole again, certain upright tip and spring wherein all are pivoted in this dowel hole, establish the locating hole that heads into correspondence to make relative axle, reach the broader correct guiding of going deep into the mis-cut angle sawing of coping saw in view of the above.

Now for a preferable embodiment and cooperate the graphic back that is illustrated in:

At first, see also shown in Fig. 1,2, a kind of coping saw of the utility model is assisted saw cutting device, is to include a base body (10), a microscler framework (20) and secondary holder (30); Wherein,

This base body (10) is to be Yi Jiaotai, its dorsal part is respectively equipped with two vertical retaining-walls (11), and in its middle breach (12) of reserving, this breach (12) center then is arranged with a shaft-pivot hole (13), and locate outwards to be extended into 1 in this shaft-pivot hole (13) and spend the scallop section (14) of angles, then be provided with the scale (141) that angle is cut apart on it, the bottom that this scallop section (14) is corresponding also is arranged with a location hole slot (15) respectively according to circumference predetermined angular (22.5 degree, 30 degree, 36 degree, 45 degree, 90 degree positions) again;

This microscler framework (20), lying in total length 1/3 place is arranged with a location axis hole (21) and cooperates a dowel (22) to wear axle to close shaft-pivot hole (13) in this base body (10) to keep the axle pivot translation of microscler framework (20) at this place, it is arranged with a through hole (23) and sets up a control lever (24) in its bottom side relative position axle pivot in end distance total length 1/3rd places (promptly with this base body (10) positioning hole groove (15) corresponding section) in addition, be that pivot button (241) and its front end articulate vertically upward a top tip (242) between among this control lever (24), it is connected with a spring (243) near rear end, and the top tip (242) of pulling the control front end for control lever (24) rear end upwards heads into its relative positioning hole groove (15); It is two distolateral and radially enlarge respectively and form rounded without exception axle sleeve (25), wherein entreat the recess (251) that is arranged with a desired depth simultaneously vertically to go deep among this axle sleeve (25) for saw blade, this recess (251) top and outwards enlarge the opening (252) that extends to form one 90 degree promoting the mis-cut angle scope, and directly predetermined angular position is as shown in Figure 3 and stagger and be arranged with plural locating hole (253) outside this axle sleeve (25);

This holder (30) is to be a C shape collar that is sleeved on this axle sleeve (25) external diameter, its open top (31) two sides and spaced and parallel set firmly two upright slide bars (32), for the positioning sleeve of a coping saw H if with (shown in Fig. 2 dotted line), its internal diameter (33) is corresponding with footpath outside this axle sleeve (25), and make the axle center (C) of the two be same straight line with sawing bottom line (E) unification of this coping saw (H), as Fig. 2, close pivoting angle sawing use to make axle shown in 3, its external diameter (34) locating hole (253) position of this axle sleeve (25) relatively is arranged with a dowel hole (35) respectively, wherein dowel hole (35) axle is provided with a dowel (36) and spring (37), establish the locating hole (253) that heads into correspondence for relative axle, make the angle pivot location of holder (30) at axle sleeve (25);

In addition, the axle sleeve (25) of above-mentioned its two end of microscler framework (20) can establish affixed one c-shaped scale plate (40) in its end face spiral shell in the lump, this scale plate is except portrayal angle in front is indicated for this holder (30) anglec of rotation, the female lug (42) that its below more is provided with a through hole (41) as shown in Figure 1, 2, utilize its perforation (41) to screw togather axle and establish a packing bolt (43), the axial packing of its packing bolt (43) of mat makes its bottom bracket axle (25) and holder (30) strong fix more;

The mat combinations thereof, and get the auxiliary saw cutting device of a kind of coping saw of the utility model, shown in Fig. 3,4; It is except possessing the person of commonly using the Plane Angle adjustment of base body (10) scallop section is used, more owing to the slick and sly and steady earth's axis pivot of holder (30) C shape collar internal diameter (33) and microscler framework (20) axle sleeve (25) external diameter cooperates, its the two axle center (C) of mat is concentric and be a straight line and can be swimmingly the coping saw sawing direction of (30) two pairs of slide bars of holder (32) be changed over required mis-cut angle shown in the figure center line with the sawing bottom line (E) of its sawtooth of coping saw, simultaneously and in that to make its recess of axle sleeve (25) (251) and cooperating of 90 degree openings (252) coping saw more deep and perpendicular to the use of machining object, it utilizes the launching of dowel (36) of holder (30) external diameter more can seek special angle rapidly and make surely.Therefore, also feel very easily and be very accurate at the vertical mis-cut angle operator bow saw in three-dimensional space, thus need to want artificial setting-out as the person of commonly using, easy to operate and practical.
