Description
Technical field:
The utility model relates to hardware ﹠ tools, relates in particular to a kind of screw and recognizes and buckle device.
Background technology:
At present, in the maintenance electrical work, run into the installation screw through regular meeting, because the screw volume is little, and a lot of installation site is to be in the deep hole, and it is very inconvenient that hand is taken screw to recognize to buckle, and also often loses screw, inefficiency.
The utility model content:
The purpose of this utility model provides a kind of screw easy to use, high efficiency and recognizes and buckle device.
A kind of screw is recognized and is buckled device, comprise screwdriver, wherein: be arranged with first sleeve pipe, second sleeve pipe successively from a end on the knife bar of screwdriver near handle of a knife, it is little stepped before big that first sleeve outer wall is the back, the outer wall dimension coupling socket of the inwall of second sleeve pipe and the first sleeve pipe front end, be equipped with spring on the knife bar in second sleeve pipe, the knife bar front portion is provided with the spring steady pin, and spring is between the first sleeve pipe front end and spring steady pin; The front end of second sleeve pipe is provided with for the head of screw to be installed and the screw fixing hole that lead screw radially penetrated and be connected to the second sleeve pipe front portion.
Described screw is recognized and is buckled device, and wherein: described screw fixing hole is umbrella.
Described screw is recognized and is buckled device, wherein: described screw fixing hole ovalize, oval-shaped long edge second sleeve outer wall circumferentially.
Described screw is recognized and is buckled device, and wherein: described screw fixing hole is the T type.
The utility model will reach following technique effect after adopting technique scheme:
Screw of the present utility model is recognized and is buckled device, when needing screw is installed, earlier first sleeve pipe is pressed forward, spring in second sleeve pipe is compressed between the spring steady pin and the first sleeve pipe front end, in edge of a knife retraction second sleeve pipe of screwdriver, the head and the lead screw of screw to be installed is fastened on second sleeve pipe by the screw fixing hole front end, unclamp first sleeve pipe, because recoil of spring stretches, pressing first sleeve pipe moves backward, drive second sleeve pipe, make the edge of a knife of screwdriver be pressed in the crown of screw to be installed at last, at this moment, the tip of screw to be installed is easy to towards position to be installed just screw to be installed to be recognized buckles, this moment, the rotary screw cutter just can be installed screw, after screw installs, screw is recognized buckle device and withdraw from from screw and get final product, therefore, screw of the present utility model is recognized and is buckled device and screw efficient is installed improves greatly, also is not easy to lose screw, greatly facilitates operating personnel.
Description of drawings:
Fig. 1 recognizes the overall structure figure that buckles device for screw of the present utility model;
Fig. 2 for screw shown in Figure 1 recognize buckle the device second sleeve pipe front end overlook the direction enlarged diagram;
Fig. 3 recognizes and buckles the device second sleeve pipe front end forward enlarged diagram for screw shown in Figure 1.
The specific embodiment:
Screw of the present utility model is recognized and is buckled device as shown in Figure 1, comprise screwdriver, wherein: be arranged with first sleeve pipe 2, second sleeve pipe 3 successively from a end on the knife bar 1 of screwdriver near handle of a knife, it is little stepped before big that first sleeve pipe, 2 outer walls are the back, the outer wall dimension coupling socket of the inwall of second sleeve pipe 3 and first sleeve pipe, 2 front ends, be equipped with spring 4 on the screwdriver rod 1 in second sleeve pipe 3, knife bar 1 front portion of screwdriver is provided with spring steady pin 5, and spring 4 is between first sleeve pipe, 2 front ends and spring steady pin 5; The front end of second sleeve pipe 3 is provided with for the head of screw to be installed and the screw fixing hole 6 that lead screw radially penetrated and be connected to the second sleeve pipe front portion.
As shown in Figures 2 and 3, described screw fixing hole 6 is umbrella; Described screw fixing hole 6 can also be arranged to ellipse, oval-shaped long edge second sleeve pipe, 3 outer walls circumferentially; Described screw fixing hole 6 can also be arranged to the T type.
When needing screw is installed, earlier first sleeve pipe 2 is pressed forward, spring 4 in second sleeve pipe 3 is compressed between the front end face of the spring steady pin 5 and first sleeve pipe 2, in edge of a knife retraction second sleeve pipe 3 of screwdriver rod 1 front end, the head and the lead screw of screw to be installed is fastened on second sleeve pipe 3 by screw fixing hole 6 front end, unclamp first sleeve pipe 2, because spring 4 resiliences are stretched, pressing first sleeve pipe 2 moves backward, drive second sleeve pipe 3, the edge of a knife of screwdriver rod 1 front end is pressed in the screw edge of a knife holddown groove on the crown of screw to be installed, at this moment, the tip of screw to be installed is easy to towards position to be installed just screw to be installed to be recognized buckles, this moment, the rotary screw cutter just can be installed screw, after screw installs, screw recognized buckle device and withdraw from from screw and get final product, therefore screw of the present utility model is recognized and buckled device and screw efficient is installed improves greatly, also be not easy to lose screw, greatly facilitate operating personnel.
