Description
Technical field
The utility model belongs to hand thread class machining tool, more particularly to a kind of multi-functional tap wrench.
Background technique
It so far need to be respectively using clamping screw tap and clamping circular die when internal screw thread and external screw thread on articulation parts
Two kinds of spanners are not capable of the combination wrench of two kinds of tools of clamping simultaneously, and the whorl work piece of simultaneous processing different size often needs
Different spanners is replaced, it is excessive thus to often result in the quantity that tool uses, and complicates.
Summary of the invention
In view of the deficiency of the prior art, the utility model provides one kind and had not only been able to achieve tapping but also had been able to achieve mantle fiber
And can the different screw tap of clamping specification and circular die multi-functional tap wrench.
Technical solution adopted in the utility model is: a kind of multi-functional tap wrench, including handle, two latch segments and
Two locking nuts;The handle is cylindrical body, and middle handle offers square central through-hole, close side on handle outer circumference surface
The left and right sides of shape central through hole offers external screw thread, and described two latch segments are oppositely arranged and sliding sleeve is mounted in handle
On, two latch segments are located at the left and right sides of square central through-hole, and described two locking nuts are separately positioned on two locks
The outside of tight block, two locking nuts are connect with handle threads.
The utility model has the beneficial effects that:
1. the utility model had not only been able to achieve tapping but also had been able to achieve mantle fiber and can the different screw tap of clamping specification and circular die
Spanner can cope with the screw tap of most of models in the market and most of common screw die, and use scope is very extensive, alleviates
Labor intensity improves work efficiency, and saves the working time, while greatly reducing the expense of tool buying.
2. the utility model has abandoned the structure of former windeisen and the handle locking of die-stock both ends, and uses independent
Locking nut locked, hand grip control is integral, the intensity of device and the stability of operation have been greatly reinforced, to mechanical row
Screw thread class work pieces process brings very big convenience in industry.
3. the utility model is on the basis of the windeisen and die-stock of former single slot, innovative design a pair has eight
Respectively there is a various sizes of taper gap in the latch segment in face, each face, each gap can fill a certain range of silk
Cone, and semicircle gap is also outputed on the taper gap of two sides above and below handle square central through-hole, to clamp screw die, thus
The tap and die that the overwhelming majority may be implemented, to realize the threaded of the internal and external threads of different size.
4. investigation discovery in machining, may require that 5 to 6 even more pull screw tap in threaded M1-M30 internal screw thread
Hand is also required to 2 to 3 die-stocks in threaded M3-M9 external screw thread, and tap wrench with screw die retail price is average currently on the market
At 50 yuan or so, assorts this kit and probably need to spend 400 yuan or so, and the utility model cost adds manufacturing expense only
100 yuan or so are needed, there is very big economic value.

Specific embodiment
As shown in Fig. 1 ~ Fig. 9, a kind of multi-functional tap wrench, including 1, two latch segment 3 of handle and two locking nuts
2;1 both ends of handle are cylindrical body, and square central through-hole 1-1, close side on 1 outer circumference surface of handle are offered in the middle part of handle 1
The left and right sides of shape central through hole 1-1 offers external screw thread 1-2, and the external screw thread 1-2 is respectively provided on the cylinder, and described two
A latch segment 3 is oppositely arranged and for sliding sleeve on handle 1, two latch segments 3 are located at a left side of square central through-hole 1-1
Right two sides, described two locking nuts 2 are separately positioned on the outside of two latch segments 3, two locking nuts 2 with handle 1
External screw thread 1-2 is threadedly coupled.
Two locking nuts 2 are circle.
As shown in Figure 4, Figure 5, the handle 1 includes square central plate 1-3 and two circular shaft 1-4;The square central plate
Offer square central through-hole 1-1 in the middle part of 1-3, the one end described two circular shaft 1-4 left and right sides with square central plate 1-3 respectively
One is made in face integrally connected, handle 1, has greatly reinforced the intensity of device and the stability of operation, outside two one end circular shaft 1-4
Periphery offers external screw thread 1-2, and two circular shaft 1-4 other ends offer external splines 1-5.
Diameter of the thickness less than two circular shaft 1-4 of the square central plate 1-3.
As shown in Fig. 6 ~ Fig. 9, each 3 middle part of the latch segment offer the circular shaft 1-4 that can slide through handle 1 and
The vertical middle part locking the through-hole 3-1, the locking through-hole 3-1 of square central plate 1-3 is can be with the circle of circular shaft 1-4 clearance fit
Shape, locking through-hole 3-1 horizontal middle is can be rectangular with square central plate 1-3 clearance fit;
Relatively matched eight kinds of specification screw tap bayonet 3-2 and two one by one are offered on the opposite face of described two latch segments 3
A screw die bayonet 3-3.
Each screw tap bayonet 3-2 is taper gap, and each screw die bayonet 3-3 is semicircle gap.
The opposite end of described two latch segments 3 is octahedron, respectively offers a kind of specification on octahedral each face
