Abstract
Description
More particularly, the present invention relates to a direct coupling and a use auxiliary bit assembly. More particularly, a person who is inexperienced in operating a screwdriver or a drill can also insert a direct coupling screw in a state of forming a right angle with a mounting surface, And to prevent the flaking of the sliced wall surface from falling to the floor or from being blown.
There are cases where nails are stuck in steel, such as when a safety gate or a door stopper is placed on a security door, or when a hinge is attached to a seat. At this time, the nail end is sharp, so use the direct screw that drills through the iron.
Direct-connection screws are drilled or pointed at the ends of the screws, so they are drilled directly into the mounting material without any additional processing. That is, the pointed end of the direct-coupling screw is strongly rotated by a screwdriver using a safety screw or an iron screwdriver which is to be inserted through a hole formed in a door stopper. The nail force is strong and can be used to fix the horseshoe in the iron gate.
However, it is practically difficult for a skilled engineer to insert the direct coupling screw so that it is exactly perpendicular to the installation surface. If the direct coupling screw is not perpendicular to the installation surface and is inclined at either side, the head of the direct- There is a problem that the door stopper or the hinge is easily shaken due to the failure to form a rigid coupling structure by fixing the door stopper or the hinge.
In addition, when a direct-coupling screw used for fixing an object easily seen from the outside such as a door stopper or a hinge is not perpendicular to the installation surface but is inclined to either side, the head of the tilted direct- .
It is an object of the present invention to provide a screwdriver capable of forming a right-handed screw in a state in which a screwdriver is formed at a right angle to the mounting surface, and that the powder of the wall surface cut off when the screw- And to provide a direct connection or use auxiliary bit assembly which is made to prevent the use.
According to an aspect of the present invention, there is provided an insertion portion to be inserted into a groove formed in a head of a direct-coupling screw is formed at one end of a mounting portion to be mounted on a chuck of a drill, A bit formed with a rotation part of the magnet; An outer tube having both ends opened to be elongated in the lengthwise direction of the bit, the inserting portion slidably moving in the inserting portion; And a compression spring which is provided in the outer cylinder and presses the rotary portion toward the mounting portion, wherein an external force other than a direction of the linear force exerted on the fastening screw by the fastening screw from the drill, Is canceled by the frictional force between the rotating part and the outer tube and the static friction between the outer tube and the engaged member.
The packing member elastically deformed by the linear external force applied from the drill to the mounting portion is engaged with the end portion of the outer cylinder which is brought into close contact with the engaged member by the recovery force of the compression spring, And the frictional force between the clamped member and the clamped member may be increased.
Wherein the compression spring includes a first compression spring and a second compression spring that are spaced apart from each other in the longitudinal direction of the outer cylinder and between the first compression spring and the second compression spring, And a guide member for guiding the head of the direct coupling screw to the insertion portion.
The outer tube may further include a plurality of through holes formed along the circumferential direction, respectively, openings formed at both ends of the outer tube, and a storage vinyl covering the outer tube to surround the through hole.
According to the present invention, among the linear external forces exerted from the drill to the mounting portion, external forces other than directions in which the direct-connection screw is fastened to the fastened member are canceled by the frictional force between the rotary portion and the external cylinder and the static friction between the external cylinder and the engaged member, It is possible to provide a direct connection or a use auxiliary bit assembly in which an inexperienced person in the operation of the drill can pinch the direct screw in a state in which the direct screw is formed at a right angle with the mounting surface.
The present invention further provides a direct connection or use auxiliary bit assembly for preventing the powder on the wall surface, which is cut off when the direct coupling screw is screwed on, from falling to the floor or from being blown, by further comprising the storage vinyl which is wrapped around the through- .

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.
The direct connection or the use auxiliary bit assembly of the present invention can be formed in a state in which a driver and a drill are inexperienced even in the operation of the drill and the direct coupling screw forms a right angle with the installation surface. As shown in Fig.
