Description
Technical field
It is to be related to a kind of tap wrench specifically the present invention relates to machining tool.
Background technology
At present, the tap wrench often used, including handle, connecting rod and chuck, it is harder in the material of fastening because handle is shorter, then it is difficult to throw into, and arduously.In addition in face of different distance job requirements and different size of nut fastening when, the tap wrench that length immobilizes, chuck is non-exchange can not then meet the use demand of people.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of tap wrench, the spanner can increase handle on handle, increase moment of torsion, the length of spanner can be accurately adjusted by being provided with graduation mark in connecting rod, different distance operation is adapted to, the tapping-head of different model can also be installed, different job requirements are adapted to.
To achieve the above object, the present invention is achieved by the following technical solutions：A kind of tap wrench, including handle, connecting rod and chuck, the handle two ends are provided with the internal thread hole of opening outwardly, the one or both ends of the handle can be threadedly coupled the lengthening handle with screw rod by internal thread hole, the connecting rod includes outer tie rod and the inside connecting rod that can be stretched in outer tie rod, it is equipped with the inside connecting rod and outer tie rod several to first through hole, the inside connecting rod is fixedly connected after passing through correspondence first through hole by the first screw rod with outer tie rod using the first nut, the outer tie rod, graduation mark is provided with inside connecting rod, the chuck upper end is provided with the second paired through hole, the second through hole of the inside connecting rod correspondence is provided with third through-hole, the chuck is connected after passing through the second through hole and third through-hole by the second screw rod with inside connecting rod using the second nut.
Further illustrate, the top of the handle is provided with circular link.
Further illustrate, handle two ends end is provided with Anti-slip cover.
Further illustrate, the described one end of lengthening handle away from its screw rod is provided with Anti-slip cover.
Compared with prior art, the present invention has the advantages that：The tap wrench can increase handle on handle one or both ends, lengthen handle, moment of torsion can be increased, strength is reduced, the length of spanner can be accurately adjusted by being provided with graduation mark in connecting rod, adapt to different distance operation, the tapping-head of different model can also be installed, different job requirements are adapted to, it is simple in construction, it is practical.
Brief description of the drawings
Fig. 1 is used for the schematic diagram for illustrating tap wrench of the embodiment of the present invention.
Parts title and sequence number in figure：1- handle 2- connecting rod 21- outer tie rod 22- inside connecting rods 3- the second nut 4- chucks 6- lengthens handle 7- links 8- the first nut 9- Anti-slip covers.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments, but not limited the scope of the invention and application：
As shown in Figure 1, a kind of tap wrench, including handle 1, connecting rod 2 and chuck 4, the two ends of handle 1 are provided with the internal thread hole of opening outwardly, the one or both ends of handle 1 can be threadedly coupled the lengthening handle 6 with screw rod by internal thread hole, and the two ends end of handle 1 is provided with Anti-slip cover 9, lengthens the one end of handle 6 away from its screw rod and is provided with Anti-slip cover 9, Anti-slip cover 9 is made of elastic silica gel, and twisting can be avoided to skid.Connecting rod 2 includes outer tie rod 21 and the inside connecting rod 22 that can be stretched in outer tie rod 21, it is equipped with inside connecting rod 22 and outer tie rod 21 several to first through hole, inside connecting rod 22 is fixedly connected after passing through correspondence first through hole by the first screw rod with outer tie rod 21 using the first nut 8, outer tie rod 21, graduation mark is provided with inside connecting rod 22, 0 degree of line of graduation mark is arranged on the lower end of inside connecting rod 22, numerical value gradually increases from the bottom up, the scale value line of fixed numbers is carved with outer tie rod 21, and be connected with the graduation mark of inside connecting rod 22, numerical value can be facilitated to read using this set, the length of spanner connecting rod 2 can also accurately be adjusted, adapt to different distance operation.The upper end of chuck 4 is provided with the second paired through hole, and the second through hole of correspondence of inside connecting rod 22 is provided with third through-hole, and chuck 4 is connected after passing through the second through hole and third through-hole by the second screw rod with inside connecting rod 22 using the second nut 3.Use this set can be with, the chuck 4 of different model can be exchanged by tightening nut, adapt to different job requirements, simple in construction, practical, the top of handle 1 is provided with circular link 7, facilitates putting in order for tap wrench.
Above is being set forth to tap wrench of the present invention; it is used to help understand the present invention; but embodiments of the present invention are simultaneously not restricted to the described embodiments; it is any without departing from the change made under the principle of the invention, modification, replacement, combination, simplify; equivalent substitute mode is should be, is included within protection scope of the present invention.
