A pruning hook includes an extension pipe 20, a cutting unit 10, an operation cord 111mounted on the pipe and connected with the cutting unit, a control sleeve 21 mounted on the pipe and connected with the cord, a guide unit 30 including two rollers, and an angle adjusting device 40. The angle adjusting device includes: a first rotation disk 41 having a plurality of peripheral positioning holes 412; a second rotation disk 42 rotatably mounted on the first and having at least one peripheral through hole 422; a mounting sleeve 43 extending through the disks; a retainer 432 secured on the sleeve and abutting the first disk to limit the mounting sleeve onto the first disk; an adjusting cap 44 rotatably mounted on the second disk; at least one fixing pin 444 extending from the cap and through the hole of the second disk and detachably locked into one of the positioning holes of the first disk; a control shaft 441 secured on the cap; a locking member 443 locked onto a distal end of the control shaft; and an elastic member 442 mounted on the control shaft.The guide unit guides and limit the operation cord to prevent it from rubbing the inner wall of the extension pipe so that it is moved easily and smoothly. In addition, the user can adjust the angle between the cutting unit and the extension pipe by operation of the angle adjusting device.
