Abstract

The utility model relates to a kind of screwdriver with exclusive PCR line function, comprise the knife bar at driver bit and cutter head rear portion, knife bar installs the rectangle rigid clamp blade of sliding along knife bar, the symmetry rigid intermediate plate bent integrally is made respectively left at the two ends up and down of clip blade, two intermediate plates are restrained to knife bar direction, extend to knife bar both sides, and keep stepping up state to knife bar, be fixedly mounted with intermediate plate handle at the reverse bearing of trend of two rigid clip.The utility model improves existing screwdriver, is ensureing, on the basis that screw uses flexibly, easily, knife bar to install the Small clamp dialling line additional, effectively get rid of outer field interfering line, make screwdriver easily insert inner layer terminals row work, reduce hand labor intensity, increase work efficiency.

Description

A kind of screwdriver with exclusive PCR line function

Technical field

The utility model belongs to power plant governing system testing technical field, particularly a kind of screwdriver with exclusive PCR line function.

Background technology

After maintenance for generation companies, the test of regulating system static and dynamic c haracteristics be done.The object doing regulating system static test is the static characteristic curve, momentary speed variation, the dead-band that measure mediation system, and whether the service behaviour of overall understanding regulating system is correct, reliable, flexible; Analyze the reason that mediation system produces defect, with correct elimination defect.The object of mediation system dynamic characteristic test is speed fling lifting curve when measuring removal of load, so that the quality of evaluated transient exactly, improves the dynamic adjustments quality of regulating system.

In process of the test, need the signals (voltage signal or current signal) such as pitch signal, tach signal to be connected in tester.During wiring, one of test connection is connected on instrument, with screwdriver, the screw in terminal block is back-outed, together with the other end of test connection line is screwed in the original signal line in terminal block, the two upper corresponding signal locations of line inserted terminals row will combined again, fix with screwdriver tighten the screws.Part terminal block is divided into internal layer and skin, when signal is voltage signal, by holding wire parallel connection access terminal block, namely need insert respectively in internal layer and outer field terminal block.When slotting test wire enters inner layer terminals row, in outer terminal block, original holding wire can block screwdriver, makes screwdriver be difficult to insert the terminal block of internal layer, need be pushed aside by the line of outer terminal block, make screwdriver enter inner layer terminals row work with hand or other instruments.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of screwdriver with exclusive PCR line function.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of screwdriver with exclusive PCR line function, comprise the knife bar at driver bit and cutter head rear portion, knife bar installs the rectangle rigid clamp blade of sliding along knife bar, the symmetry rigid intermediate plate bent integrally is made respectively left at the two ends up and down of clip blade, two intermediate plates are restrained to knife bar direction, extend to knife bar both sides, and keep stepping up state to knife bar, be fixedly mounted with intermediate plate handle at the reverse bearing of trend of two rigid clip.

And two rigid clip left end edges roll into the hollow cylinder that diameter is 3mm respectively.

And described two rigid clip are long × wide is 25mm × 15mm.

Advantage of the present utility model and good effect are:

The utility model improves existing screwdriver, is ensureing, on the basis that screw uses flexibly, easily, knife bar to install the Small clamp dialling line additional, effectively get rid of outer field interfering line, make screwdriver easily insert inner layer terminals row work, reduce hand labor intensity, increase work efficiency.

Detailed description of the invention

Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of screwdriver with exclusive PCR line function, as shown in the figures 1 and 2, comprise the knife bar 2 at driver bit 1 and bull rear portion, knife bar installs the rectangle rigid clamp blade 5 of sliding along knife bar, the symmetry rigid intermediate plate 4 bent integrally is made respectively left at the two ends up and down of clip blade, two intermediate plates extend to knife bar both sides to the convergence of knife bar direction, and keep stepping up state to knife bar, are fixedly mounted with intermediate plate handle 6 at the reverse bearing of trend of two rigid clip.

In concrete enforcement of the present utility model, two rigid clip left end edges roll into the hollow cylinder 3 that diameter is 3mm respectively, and hollow cylinder not only can keep contacting with the flatness of knife bar, avoid the damage to interfering line when separating interfere with guidewire simultaneously.

In concrete enforcement of the present utility model, described two rigid clip are long × wide is 25mm × 15mm; This size not only effectively can realize the operation of separately interfering line, and separately the space of interfering line can realize again the flexible operating of driver bit just, and cost control is low.

The using method of the utility model instrument is

As shown in figure 3 or 4, withstand respectively with the hollow cylinder of two on Small clamp " interfering line " of upper and lower two outer terminals; Left hand mediates intermediate plate handle, and intermediate plate is strutted " interfering line ", and screwdriver is inserted the screw of inner layer terminals row by the right hand, turns screw, fulfils assignment.

Claims

1. one kind has the screwdriver of exclusive PCR line function, comprise the knife bar at driver bit and cutter head rear portion, it is characterized in that: on knife bar, install the rectangle rigid clamp blade of sliding along knife bar, the symmetry rigid intermediate plate bent integrally is made respectively left at the two ends up and down of clip blade, two intermediate plates are restrained to knife bar direction, extend to knife bar both sides, and keep stepping up state to knife bar, be fixedly mounted with intermediate plate handle at the reverse bearing of trend of two rigid clip.

2. the screwdriver with exclusive PCR line function according to claim 1, is characterized in that: two rigid clip left end edges roll into the hollow cylinder that diameter is 3mm respectively.

3. the screwdriver with exclusive PCR line function according to claim 1, is characterized in that: described two rigid clip are long × wide is 25mm × 15mm.
