Benefits of technology
The present invention provides a pair of bidirectional pipe bending pliers that have improved convenience of use by being provided with bidirectional pipe-bending paths. The pliers can bend two differently sized pipes. The pliers have a first handle and a second handle, with a first pipe-bending portion and a second pipe-bending portion. The first and second pipe-bending portions have different bending paths, which allows for easier bending of pipes in different directions. The pliers can be opened and closed to carry out clamping operation on the pipes. The technical effects of the invention are improved convenience and ease of use, as well as the ability to bend pipes in different directions.
Problems solved by technology
However, a pair of conventional pipe bending pliers is only provided for single direction bending and is only used for single sized pipe bending since the jaw size of the pipe bending pliers is not adjustable.
Hence, different pipe bending pliers should be prepared when bending different sized pipes, causing inconvenience when carrying and using the pipe bending pliers.

Embodiment Construction
[0020]The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
[0021]Referring to FIGS. 1-9, a pair of bidirectional pipe bending pliers in accordance with the present invention comprises: a first handle 10, a second handle 20 and a pivot member 30 for connecting the first and second handles 10, 20 together.
[0022]The first handle 10 includes a first handle portion 11, a first pipe-bending portion 12 and a first pivoting portion 13 connected between the first handle portion 11 and the first pipe-bending portion 12. The first handle portion 11 for user's grip is located at one end of the first handle 10, and the first pipe-bending portion 12 is located at another end of the first handle 10. Along an inner surface of the first pipe-bending portion 12 are formed a semicircular first bending groove 121 and a semi...

Abstract
A pair of bidirectional pipe bending pliers comprises: a first handle and a second handle. The first handle includes a first handle portion and a first pipe-bending portion, and the second handle includes a second handle portion and a second pipe-bending portion. When the first and second pipe-bending portions are closed toward each other to carry out clamping operation, the first and third bending grooves will define a first pipe-bending path therebetween, while the second and fourth bending grooves will also define a second pipe-bending path, the first and second pipe-bending paths extend in different axial directions.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a pair of pliers, and more particularly to a pair of bidirectional pipe bending pliers.[0003]2. Description of the Prior Art[0004]Conventionally, large-diameter pipe bending requires the use of professional pipe bending machine, while small-diameter pipe bending is normally carried out with manual pipe bending pliers. However, a pair of conventional pipe bending pliers is only provided for single direction bending and is only used for single sized pipe bending since the jaw size of the pipe bending pliers is not adjustable. Hence, different pipe bending pliers should be prepared when bending different sized pipes, causing inconvenience when carrying and using the pipe bending pliers.[0005]The present, invention has arisen to mitigate and / or obviate the afore-described disadvantages.SUMMARY OF THE INVENTION[0006]The primary object of the present invention is to provide a pair of bidirecti...
