US Patent 7370423 Long-arm gardening shears having angle adjustable function

A pair of long-arm gardening shears include a main body, a first casing, a second casing, a cutting blade assembly, a retaining member, a push button, and a spring. Thus, the angle between the cutting blade assembly and the main body is adjusted so that the length of the long-arm gardening shears is adjusted, thereby facilitating a user operating the long-arm gardening shears to shear the lawn at a lower height and the branches at a higher level. In addition, the use only needs to press the push button so as to rotate the cutting blade assembly and to release the push button so as to lock the cutting blade assembly, thereby facilitating the user adjusting the angles of the long-arm gardening shears.
