The pruning shears (100) comprise a wheel (150) having a frusto-conical shape connected rotatably to the handle (140)； the wheel (150) comprises a first end (151) and a second end (152), the diameter (D1) of the wheel (150) at the first (151) end being smaller than the diameter (D2) of the wheel at the second end (152)； the driving line (120) is arranged into the spiral groove (153) and wound at least once around the wheel (150) along the spiral groove (153) at the first (151) end of the wheel (150)； a second end (122) of the driving line (120) is attached to a second end (132) of the elongated body (130)； and the driving line (120) wound around the wheel (150) is arranged to move towards the second end (152) of the wheel (150) as a result of unwinding of a part of the driving line (120) from around the wheel (150) and winding of another part of the driving line (120) to around the wheel (150) for decreasing the distance between the first end (121) of the driving line (120) and the second end (122) of the driving line (120) resulting in a movement of the spring-biased blade (111) in relation to the jaw (112), when the handle (140) is moved along the elongated body (130).
