Abstract

The utility model relates to an installing device for wood screws of electrical tool fittings, which is used for installing and positioning wood screws and is composed of components such as a positioning regulator, a material clamping head, a clamping head handle, etc., wherein, the wood screws are placed below a screw driver at the lower part of the material clamping head, the screw driver is driven to rotate by an electric drill through the clamping head handle, and the screws are nailed in a wood product. The screw driver can be replaced by flat-head screw drivers or cross-head screw drivers of different sizes according to the thickness of the wood screws and different end openings. The depth of the screws nailed in the wood product can be controlled by rotating a regulating disk. The installing device has the characteristics of labor saving, time saving, convenient use, controllable installing depth of the screws, etc.

Description

Mounting unit for wood screw

The utility model belongs to the electric tool accessory, installs, locatees as wood screw.At present usually the mode of rotary screw cutter is installed wood screw by hand, screws spiral shell after needing punch with analogs such as drill bits earlier and twist when wood screw is big, and work is inconvenient like this, take a lot of work, time-consuming, and the degree of depth that screw is installed is difficult to control.

The purpose of this utility model is a kind of easy to use for seeking, the wood screw erector that the screw emplacement depth is controlled.

For this purpose, adopted following technical scheme:

Adopt a chuck handle, this chuck handle one end is polygonal bar, the other end is the round bar with inner polygonal hole, inner polygonal hole matches with the screwdriver with polygonal nut head, the polygonal rod end and the electric drill of chuck handle match, electric drill rotates by the wood screw that the chuck handle drives under the screwdriver, so that screw is hammered in the plank.

Be with a location adjuster at the middle part of chuck handle.Positioning regulator is made up of adjustment disk and collet body.Adjustment disk is that inside has three groups of dovetail grooves that are mutually 120 degree different depths, and the outside is the disk of teeth groove.Collet body is the pipe that the periphery, end has three salient points that are mutually 120 degree, and its inner upper end and chuck handle match.The bar number of three groups of dovetail grooves is identical on the adjustment disk, and every group of dovetail groove be mutually 120 degree, and the degree of depth of corresponding three-flute is identical all by depth order arrangement, corresponding one by one.The rotation adjustment disk makes three salient points of collet body be arranged in the dovetail groove of different depth, with the control screw depth of packing into, makes the screw location.

A material folding head is joined at the pipe place in chuck handle bottom, and the material folding head is made up of material folding pipe, ball, straight shape spring, volute spring and spring housing.The material folding pipe is that the middle part has flange, and an end has the pipe in 3～6 holes at grade.Ball is positioned at the hole of material folding pipe, and straight shape spring is pressed between the flange and collet body of material folding pipe, and volute spring is stretched between bonnet and the spring housing.By overcoat, bonnet, packing ring, spring etc. material folding head, positioning regulator, chuck handle are formed one and constitute the wood screw erector.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 wood screw erector is always schemed;

Fig. 2 collet body front view;

Fig. 3 collet body BB view;

Fig. 4 adjustment disk front view;

Fig. 5 adjustment disk C is to view.

In Fig. 1, chuck handle (11) one ends are the hexagonal bar, and the other end is the round bar with inner hexagonal hole.Screwdriver (12) head is a hex nut, matches with the inner hexagonal hole of chuck handle, but according to the flathead screwdriver or the cross head drivers of the thickness difference and the different sizes of wood screw termination openings difference adapted of wood screw.The round bar end and the material folding head of chuck handle match.The material folding head is made up of material folding pipe (1), ball (2), straight shape spring (4), volute spring (5) and spring housing (6).Material folding pipe (1) has the pipe of flange for the middle part, and on the same plane of its end, have four across to the perforation, also can open a plurality of holes at grade, as 3～6 holes.Is furnished with the ball (2) that diameter is slightly less than the aperture in the hole.The ball both sides are exposed at outside the material folding tube wall, and straight shape spring (4) is between the flange and collet body (8) of material folding pipe (1), and volute spring (5) is stretched between spring housing (6) and the bonnet (7).Overcoat (3) is the tapered cylinder in end, and its end awl mouth matches with ball (2), and top and bonnet match.

From the front view (Fig. 2) of collet body (8) and BB view (Fig. 3) thereof as seen, collet body (8) is mutually the pipe of three salient points of 120 degree for the periphery, end has, and its inner matching with the chuck handle partly is hexagon.

Is that inside has three groups of dovetail grooves that are mutually 120 degree different depths from the front view (Fig. 4) and the C thereof of adjustment disk (10) to the visible adjustment disk of view (Fig. 5), and the outside is the disk of teeth groove.The bar number of three groups of dovetail grooves is identical, can be split into 8～10 grooves, and three groups of dovetail grooves are all arranged by depth order, corresponding one by one, be mutually 120 degree, corresponding three groove depth are identical, the degree of depth of groove can be regulated according to needs, and in the present embodiment, the degree of depth of groove can change between 3.5 millimeters to 8.5 millimeters.

Collet body (8), straight shape spring (9) are formed positioning regulator with adjustment disk (10), are sleeved on the pipe and the hexagonal intersection of chuck handle (11).

As shown in Figure 1, positioning regulator, material folding head, chuck handle etc. are formed one, constitute the wood screw erector by overcoat (3), bonnet (7), packing ring, straight shape spring (4), volute spring (5) and spring housing (6) etc.

During use, the material folding head is upwards pushed away, ball with on move, slip in the cone space of overcoat, the screwdriver edge of a knife exposes, the wood screw that desire is installed comes directly towards the edge of a knife that sulculus is aimed at screwdriver, remove upwards thrust, material folding pipe (1) resets, ball (2) is positioned at the hole of material folding pipe (1) again, clamp wood screw, make wood screw be in shape to be installed, rotate adjustment disk (10) then on demand, three salient points of collet body (8) are positioned at the bottom of the dovetail groove of adjustment disk (10), the hexagonal rod end of chuck handle (11) is linked to each other with electric drill, because the interior hexagonal of chuck handle (11) hexagonal bar and collet body (8) end etc. is connected, when electric drill drives chuck handle (11) rotation, screwdriver (12), wood screw, positioning regulator, material folding is first-class rotates thereupon, under exerting oneself simultaneously, press, wood screw then, screwdriver (12), positioning regulator, move down with chuck handle (11), the material folding pipe moves on relatively, screw hammers in the woodwork, when the lower surface of adjustment disk (10) and bonnet (7) when contacting, moves down and stops, wood screw hammers into the degree of depth and is restricted, when removing downward pressure, positioning regulator and material folding Guan Jun reset under spring action, finish wood screw and install.

When rotation adjustment disk (10) makes three salient points of collet body (8) be arranged in the dovetail groove of different depth of adjustment disk (10), adjustment disk (10) lower surface is different thereupon with distance between bonnet, it is also different thereupon that wood screw hammers into the degree of depth, thereby the available adjustment dish is regulated the injection degree of depth of wood screw, to reach the purpose of wood screw location and installation.

When having province worker, province when adopting the utility model and electric drill to join with the installation wood screw, the advantage such as easy for installation and screw fitting depth is controlled.
