Technical Field

The invention relates to a connector, in particular to a six-diamond self-tapping screw connector.

Background

With the continuous development of modern society industry, a plurality of self-tapping screws or quick-threading screws of different types and models are available on the market, and are steel quick-mounting fasteners with surfaces galvanized and passivated. Tapping screws are often used for connecting thin metal plates (steel plates, saw plates, etc.). During connection, a thread bottom hole is formed in the connected piece, then the self-tapping screw is screwed into the thread bottom hole of the connected piece, and the self-tapping screw needs to form a bottom hole in a steel plate, so that high requirements are required on tools during drilling of the self-tapping screw.

At present, the mode of drilling the self-tapping screw into the steel plate or the saw plate is usually operated by a manual operation using a hexagonal wrench, and although the operation by using the hexagonal wrench is stable, the working efficiency is low because the hexagonal wrench is rotated by the manual operation to drill the self-tapping screw into the saw plate.

In addition, some application electric drills will self-tapping screw bore into the saw board, and the speed of application electric drill is even fast, but is difficult to guarantee self-tapping screw's stability when the electric drill high-speed rotation, needs to apply pressure toward the saw board direction in addition, more is difficult to with self-tapping screw fixed, and easy direct drilling with self-tapping screw is inclined to one side or structural dropping from the electric drill influences self-tapping screw and bores efficiency and effect.

Therefore, there is a need to develop a hexagonal self-tapping screw connector which can improve work efficiency and can stabilize a self-tapping screw when screwing.

Disclosure of Invention

In order to overcome the defects that when a hexagonal wrench is used for turning a self-tapping screw into a saw plate, the working efficiency is low, the stability of the self-tapping screw is difficult to ensure by using an electric drill, and the drilling efficiency and the drilling effect of the self-tapping screw are influenced, the technical problems of the invention are as follows: provided is a hexagonal self-tapping screw connector which can improve work efficiency and can stabilize a self-tapping screw when a screw is turned.

The utility model provides a six rhombus self tapping screw connectors, including rotary joint and butt joint axle, be connected with the butt joint axle on the rotary joint, still including the pivot, the slider, the swinging arms, the arc stopper, the one end that butt joint axle was kept away from to the rotary joint is opened there is hexagonal draw-in groove, the equal rotary type in both sides is equipped with the pivot about the hexagonal draw-in groove, the pivot is connected with the rotary joint rotary type, the pivot front end is connected with the slider, both sides all are equipped with the swinging arms about the hexagonal draw-in groove, it has a word groove to open on the swinging arms, the slider is located with a word inslot and sliding fit, first spout has all been opened to both sides about in the rotary joint, first spout and hexagonal draw-in groove intercommunication, the tail end of two swinging arms all is equipped with the arc stopper, two upper and.

Further explaining, still including the linkage subassembly, the linkage subassembly is including driving frame, rack, gear and first spring, and the second spout has all been opened to both sides in the rotary joint, and the second spout communicates with hexagonal draw-in groove and first spout respectively, and second spout internal sliding formula is equipped with the driving frame, is connected with first spring between driving frame and the hexagonal draw-in groove inner wall, and the upper and lower both sides of driving frame all are equipped with the rack, are equipped with the gear in the pivot, and wheel and rack toothing.

Further explain, still including the subassembly that resets, the subassembly that resets is equipped with the sliding block including second spring and sliding block on the first spout, and be connected with the second spring between sliding block and the first spout inner wall.

The beneficial effects are that: according to the invention, the self-tapping screw is fixed and limited by matching the hexagonal clamping groove and the arc-shaped limiting block, so that the self-tapping screw is prevented from swinging to cause deviation or falling of the self-tapping screw when rotating at a high speed, and the swinging rod is driven to swing by the linkage assembly when the self-tapping screw is inserted into the hexagonal clamping groove, so that the swinging rod does not need to be manually rotated, the working efficiency is improved, and the swinging rod does not need to be manually pulled out from the first sliding groove under the action of the reset assembly, so that the labor is saved.
