Abstract

The utility model discloses a screw device with a bidirectional use function. The screw device is formed by a handle and a bidirectional screw; one end of the bidirectional screw is a threaded nail while the other end is of a square pillar structure; the end part of the square pillar is a plain end nail; magnets are embedded into the end parts of the threaded nail and the plain end nail; the handle is of a two-section telescopic structure; a square hole is formed in the head of the handle; the size of the square hole is matched with size of the square pillar of the bidirectional screw; the middle of the handle is a cavity; the tail of the handle is provided with a spherical cap capable of being opened by screwing; multiple dents are arranged on the spherical cap; the bidirectional screw has different models and is arranged in the cavity of the handle. When being used for nailing joints of timbers and timber plastic materials, the screw device with the bidirectional use function is not influenced by the screw length and the thickness influence of objects, no nailing marks exist on the surface, and the nailing firmness and appearance effect are good.

Description

Screw means that can two-way use

Technical field

Model utility relates to the repair outfit of a kind of timber, Wood-plastic article, particularly a kind of repair outfit of building composite plastic template.

Background technique

At wood quality, Wood-plastic, be can often occur piece, seam during each main article are processed at present, in most cases, the processing of piece, seam is adopt gluing or bind from outside, when gluing, the quality of piece, seam depends primarily on cohesiveencess and the intensity of colloid, receives again the limit value of nail length and article thickness while binding from outside, after having bound, from outside, can see ailhead part vestige, affect it and bind fastness and appearance effect.

Summary of the invention

Technical problem to be solved in the utility model is to take wood quality, Wood-plastic while being main sheet material, bulk piece overlap joint in order to solve, from outside, bind the defect that is limited to nail length and article thickness, a kind of a kind of two-way device of binding of binding from article inside is provided.

For solving this technical problem, the utility model provides a kind of screw means that can two-way use, by handle and Bidirectional screw, formed, one end of described Bidirectional screw is drive screw, the other end is square column structure, the end of this square column is flat mouth nail, and the end of described drive screw and flat mouth nail is inlaid with magnet; Described handle is 2 joint Collapsible structures, and its head is provided with a square hole, and the size of this square hole is mated with the square column of Bidirectional screw, and the middle part of described handle is cavity, at the afterbody of handle, is provided with the spherical cap that can outward winding, and this spherical cap is provided with many indentures.

Described Bidirectional screw is provided with different models, is placed in the cavity of handle.

Described Bidirectional screw is that steel sizing processing is made by cutting.

Described handle is that plastic material or timber are made.

Beneficial effect: while utilizing the utility model to bind the seam of wood quality, Wood-plastic, be not subject to nail length and article thickness effect, and surface is without determining trace, binds fastness and appearance effect good.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model Bidirectional screw.

In figure: 1 handle, 11 square holes, 12 cavitys, 13 spherical cap, 2 Bidirectional screws, 21 drive screws, 22 square column types, 23 flat mouth nails.

Embodiment

Below in conjunction with drawings and Examples, the utility model is specifically described.

Figure 1 shows that structural representation of the present utility model.

The utility model is comprised of handle 1 and Bidirectional screw 2.

Figure 2 shows that the structural representation of the utility model Bidirectional screw.

One end of described Bidirectional screw 2 is drive screw 21, and the other end is square column 22 structures, and the end of this square column is flat mouth nail 23, and the end of described drive screw 21 and flat mouth nail 23 is inlaid with magnet.

Described handle 1 is 2 joint Collapsible structures, its head is provided with a square hole 11, and the size of this square hole 11 is mated with the square column 22 of Bidirectional screw 2, and the middle part of described handle 1 is cavity 12, afterbody at handle 1 is provided with the spherical cap 13 that can outward winding, and this spherical cap 13 is provided with many indentures.

Described Bidirectional screw 2 is provided with different models, is placed in the cavity 12 of handle 1.

Described Bidirectional screw 2 is processed and is made by cutting for steel sizing.

Described handle 1 is made for plastic material or timber.

Using method of the present utility model: when wood quality, Wood-plastic relative article seam are bound, first square column one end of Bidirectional screw 2 is inserted in square hole corresponding in handle 1, then the screw of Bidirectional screw 2 21 one end are screwed into seam one side, then handle 1 is taken away, expose other one end square column 22,, required piece another part is placed in to flat mouth and follows closely 23 places, hammering is bound, and seam both sides article can be bound tightly; When the degree of depth is darker, the telescopic section of handle can be pulled out, after lengthening of handle, can install the position compared with the degree of depth.

While utilizing the utility model to bind the seam of wood quality, Wood-plastic, be not subject to nail length and article thickness effect, and surface is without determining trace, binds fastness and appearance effect good.

The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
