TITLE:SHEARS BACKGROUND OF THE INVENTION

The present invention relates to a pair of shears. More particularly, the present invention relates to a pair of shears which has a main handle to be rotated and returned to its original direction.

Referring to FIG. 1, a pair of conventional shears 10 comprises a pair of blades 18, a main handle 12, an auxiliary handle 17, a lug 15, and a shaft 11. The lug 15 is connected to the auxiliary handle 17. The lug 15 has a blocking flange 151. The pair of blades 18 are disposed on the lug 15 and the auxiliary handle 17. The shaft 11 is disposed on a bottom of the lug 15. The shaft 11 has an annular groove 14. The main handle 12 has a protuded block 16, a round hole 121 receiving the shaft 11, and a circular hole 122 communicating with the round hole 121. A bolt 13 is inserted in the annular groove 14 via the circular hole 122. The protuded block 16 engages with the blocking flange 151. After the main handle 12 is rotated, the main handle 12 cannot return to its original direction.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a pair of shears which has a main handle to be rotated and returned to its original direction.

1 Another object of the present invention is to provide a pair of shears which has a main handle having a protection bow to protect fingers of a user.
