This utility model, when specifically applying, is chosen plectane retainer with M9 circular die external diameter 25, is chosen the circle of M6 external diameter 20
As a example by screw die, i.e. circular die external diameter selected by this example is 20, and the die sleeve inner ring internal diameter of plectane retainer is 25, in order to avoid circular die
Not level of placing in die sleeve causes mantle fiber waste product occur, or circular die drops out from die sleeve, chooses internal diameter and is less than 20
Packing ring puts into die sleeve together with circular die, during fixed disc facing silk, for avoiding each screw elongation different, causes circular die
Center is deviateed, and uses thin wall cylindrical to be enclosed within outside circular die, plays the role of positioning.
Folding rod in this utility model has two functions: one is in use more conform to human engineering,
Make work convenient, that it changes conventional horizontal hand grip, make cross bar vertical with montant, enter in corresponding pin-and-hole with bearing pin
Row is fixing；Two is when needs are laborsaving, makes cross bar and montant level, is fixed, so in the pin-and-hole that bearing pin is corresponding again
The arm of force can be increased, i.e. can reach labour-saving purpose and the most effectively save and deposit space shared when carrying.
When overlapping large-sized needs reinforcing with this plectane retainer, in order to laborsaving, length can be regulated by expansion link, will
The handlebar of one end screws off, and boosting-rod is screwed in, and can increase the arm of force, reaches labour-saving effect.
When folding rod is applicable to screw tap drift holder, operational approach is consistent with the above, can save space when carrying and deposit,
Can be laborsaving during use, but, folding rod can only be located at the right handles being fixedly mounted on the right side of strand hands frame.Expansion link is also suitable
In screw tap drift holder, can only be arranged at mobilizable handle end, operational approach is consistent with the above.In order to join with various sizes of screw tap
Closing convenience when using and place screw tap, the handle of screw tap drift holder is divided into movable end and fixing end, when changing screw tap, needs
First the handle of movable end is unscrewed, screw tap is taken out, places into screw tap, tighten, so, can only be in movable handle one end
Arranging expansion link, the other end arranges folding rod.
Plectane retainer of the present utility model can install many specifications circular die and laborsaving die handle, makes together with circular die
With, for threading, screw tap drift holder is laborsaving strand hands, and screw tap is used together, for machining internal thread.
The part added in this utility model all can be selected for standard component, low price, and production cost reduces.For avoiding making
Too much by the quantity of packing ring and thin-walled cylinder, according to GB, the specification of screw die and die handle can be divided, intend according to circle
Screw die external diameter, three are one group and divide, and manufacture die handle, the circular die that external diameter is little according to maximum outside diameter, divide as required
Not choosing the thin wall cylindrical of suitable packing ring, as a example by M1～M9, circular die external diameter is respectively 16,20,25, can divide one group into,
Die handle can be chosen according to Φ 25, choose packing ring and thin-walled cylinder further according to standard.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of this utility model claims.
