Description
Technical field
The utility model relates to a kind of tools, more particularly, to a kind of high-intensitive screw tap drift holder.
Background technique
Windeisen is a kind of tool for twisting hand for clamping set tap in machining internal thread.Traditional windeisen
A kind of screw tap or a kind of screw die can only be often operated, use scope is smaller, and versatility is poor.Chinese patent discloses a kind of silk
Cone twists hand (publication number: CN205074972U) comprising left handle, right handles twist hand frame, jacking block, left handle, right handles difference
Including section, the changeover portion of connecting sleeve, casing, connection strand hand frame section can be rotated by 90 ° upwards；The outer circle that connection twists hand frame section, which has, matches
The screw thread of trap pipe；It can be rotated by 90 ° the changeover portion of section and connecting sleeve upwards by bolted splice, can be rotated by 90 ° upwards；Even
The outer circle of the changeover portion of female connector pipe has the screw thread of cooperation casing, can suitably adjust left hand by adjusting threaded connection length at two
Handle, right handles length carry out cooperating needs.But the use of this screw tap drift holder is for a long time, twists hand ontology due to wall thickness
It is relatively thin, it is broken to will lead to and twist hand ontology in edge, and positioning is more inaccurate when screw tap drift holder clamping, is easy to disengage.
Utility model content
The utility model is to provide a kind of high-intensitive screw tap drift holder, mainly solves screw tap present in the prior art and twists
The use of hand for a long time, twists hand ontology since wall thickness is relatively thin, is broken to will lead to and twist hand ontology in edge, and screw tap
It is more inaccurate to twist positioning when hand clamps, the technical problem of easy disengagement etc..
Above technical problems of the utility model are mainly solved by the following technical scheme:
The high-intensitive screw tap drift holder of the utility model, including hand ontology is twisted, the strand hand is set inside the body cavity,
The edge at cavity both ends is equipped with cavity fillet, and the wherein one end for twisting hand ontology, which is worn, is connected to fixed handle, and fixed handle inner end connects
It is connected to fixed block, the other end for twisting hand ontology is threaded with flexible handle, and the inner end of flexible handle is connected with movable block.This reality
Cavity fillet is set with the novel edge at cavity both ends, so that its arc transition increases the wall thickness of corner, fixed
Ambassador will not be crossed because of stress when block and movable block clamping screw tap twists the fracture of hand ontology.
Preferably, the outer end edge of the fixed block is equipped with the fixed block fillet to match with cavity fillet, it is living
The outer end edge of motion block is equipped with the movable block fillet to match with cavity fillet.The utility model is in fixed block, movable block
End adds fillet, makes itself and the cavity fillet precision-fit in cavity, stress is more uniform when clamping in this way.
Preferably, the inner end of the fixed block is right-angle notch, the inner end of movable block is equipped with forked tail port.Right-angle notch
Angle be 90 °.
Preferably, the strand hand ontology generally octagonal.It twists hand ontology both ends to shrink, cavity fillet is just arranged in
Contraction place.
Preferably, twisting for the movable block two sides is equipped with longitudinal sliding slot in hand ontology, slidably connected in sliding slot
Jacking block is positioned, one end that positioning jacking block is contacted with movable block is equipped with rubber block, and the other end for positioning jacking block is equipped with pressure spring.Positioning top
Block can be moved in sliding slot, and under the action of pressure spring, rubber block can be withstood on movable block, and such movable block is run to
It can be compacted behind position, to should not be disengaged when clamping screw tap.
Preferably, embedded with the idler wheel being arranged in pairs, the two sides of idler wheel contact positioning jacking block in the sliding slot.It utilizes
Idler wheel can guarantee the smoothness that positioning jacking block moves up and down, it is prevented to get stuck when pushing.
Therefore, the screw tap drift holder of the utility model after prolonged use, twists hand ontology due to the corner at cavity both ends
Place is equipped with cavity fillet, is broken so as to prevent from twisting hand ontology in edge, and positioning is more smart when screw tap drift holder clamping
Really, it is not easy to it disengages, it is simple and reasonable for structure.
