Abstract

The utility model discloses a screw installation fixing device, which is composed of an outer sleeve and two inner clamp plates, wherein the two inner clamp plates can dovetail to form a circular ring and the inner section of the circular ring which is formed by the inner clamp plates is in a big end up taper. Fixing columns are arranged on the inner clamp plates, fixing holes are arranged on the outer sleeve, the inner clamp plates are fixed in the outer sleeve through the fixing columns and the fixing holes and springs are sheathed on the fixing columns. The design of the tapered slotted holes of the inner clamp plates of the utility model make the inner clamp plates separate toward both sides of the utility model by screw caps follow the embedding of screws, the screw caps can not be clamped and the force generated by the springs can prevent the excursion of the screws. Therefore, when the screws are installed, the outer sleeve can be supported by hands, the screws do not need to be directly supported by hands, the situation that a screwdriver slides off to damage the hands of people can be avoided, and simultaneously, the installation of the screws can be convenient and quick.

Description

The screw fixing holder

Technical field:

The utility model relates to a kind of fixator that screw is used of installing.

Background technology:

When on woodenware, screw being installed, normally hold screwdriver with one, an other hand steered firmly screw, firmly the rotary screw cutter makes screw pierce woodenware, and for convenience of the application of force, the center line of screw and screwdriver should be consistent.But because the specification difference of screw, the size of the notch on the screw terminal is also inequality, the situation that the edge of a knife of the screwdriver of use and the notch on the screw occur misfitting through regular meeting; And sometimes screw hammer into the angle on woodenware plane neither be vertical, more strengthened the difficulty of operation.Will cause like this exerting oneself when excessive when the rotary screw cutter, the center line of screw and screwdriver has deviation slightly, and screwdriver just skids off from the notch of screw easily, and damaging buttresses the finger of screw.

Summary of the invention:

The purpose of this utility model is that a kind of screw fixing holder is provided.It can make things convenient for the fitting operation of screw, solves the problem of screwdriver landing wound hand.

The technical solution of the utility model.The screw fixing holder, it is made up of outer sleeve 1 and 2

inner splints

2,2 inner splints 2 coincide into annular, and the interior cross section of the annulus that inner splint 2 forms is up big and down small taper 3, on inner splint, be provided with fixed leg 4, have fixing hole 5 on outer sleeve 1, inner splint 2 is fixed in the outer sleeve 1 by fixed leg 4 and fixing hole 5, and is with spring 6 on fixed leg 4.

Aforesaid screw fixing holder is provided with lasso 7 above inner splint 2.

Aforesaid screw fixing holder is provided with base 8 below inner splint 2.

Aforesaid screw fixing holder is connected with connecting rod 9 on outer sleeve 1, the top of connecting rod 9 is connected with the clamping ring 10 that can be enclosed within on the screwdriver knife bar 11.

The utility model adopts the taper slotted eye in the middle of the inner splint to clamp screw, and screwdriver stretches into from the outer sleeve top, with hand steered firmly outer sleeve, screw is installed.The design of inner splint taper slotted eye makes inner splint along with the going deep into of screw, and by screw cap inner splint is separated to both sides, can not block screw cap, and the power that spring produces can prevent the screw skew.After in screw enters woodenware, take out screwdriver, under the effect of spring, inner splint closes up again.By using the utility model, with hand steered firmly outer sleeve, no longer need directly to buttress screw, the situation of having avoided the screwdriver landing to hinder hand occurs, simultaneously because the restriction of outer sleeve and inner splint, make the center line of screw and screwdriver be consistent, allow the easier for installation of screw, quick.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment:

Embodiment of the present utility model: as shown in Figure 1, the screw fixing holder is made up of outer sleeve 1 and 2 inner splints 2, inner splint 2 is made into semicircular arc, 2 inner splints 2 coincide into annular, the interior cross section of the annulus of its formation is up big and down small taper 3, the diameter on taper 3 tops is greater than the diameter of the screw ailhead of installation, on inner splint 2, produce 2 fixed legs 4, open 2 fixing holes 5 respectively in the both sides of outer sleeve 1, cover upper spring 6 on fixed leg 4, first fixed leg 4 with an inner splint 2 passes the fixing hole 5 on the outer sleeve 1, then spring 6 is compressed, make inner splint 2 be adjacent to the inwall of outer sleeve 1, in the outer sleeve 1 of again another piece inner splint 2 being packed into.For easy to use, a lasso 7 is installed above inner splint 2, the interior circle of lasso 7 can further limit the skew of screwdriver, guarantees the application of force direction of screwdriver.Screw thread is produced in lower end at outer sleeve 1, installs a base 8, and the interior circular diameter of base 8 can make the fixing more stable of inner splint 2 like this greater than the diameter of the screw ailhead of installing.Flexibly connect the connecting rod 9 of a L type on outer sleeve 1, the top of connecting rod 9 connects a clamping ring 10, clamping ring 10 can about open.Clamping ring 10 be positioned at outer sleeve 1 directly over, the knife bar 11 of screwdriver can be passed clamping ring 10 during use, to fix screwdriver, the flexible connection of connecting rod 9 and outer sleeve 1 makes outer sleeve 1 and the screwdriver knife bar 11 can free opening and closing, so just can from inner splint 2, take out screwdriver easily, screw is packed in the inner splint 2.The utility model in use, entangle with the knife bar 11 of clamping ring 10 with screwdriver, tilt linkage 9 makes screwdriver offset from outer sleeve 1, screw is put into outer sleeve 1, clamp by inner splint 2, return positive connecting rod 9 then, in the knife bar 11 insertion outer sleeves 1 with screwdriver, the right hand is held screwdriver, left hand buttresses outer sleeve 1, and the rotation screw cutter can pierce screw in the woodenware easily and fast.
