Pruning shears having both functions of hanging on a tree branch and absorbing a shock, the pruning shears comprising: a first body configured to include a first cutting portion in which a plurality of first slip prevention depressions configured to prevent a slip during cutting of a tree branch is formed, on one side thereof, and a first grip portion which has a sliding portable saw accommodation means configured to cut off a tree branch or stem outside a cutting range of the pruning shears, on a remaining side thereof; a second body configured to include a second cutting portion which corresponds to the first cutting portion 11 on one side thereof, and a second grip portion which is disposed on a remaining side thereof; a hinge member configured to hinge the first body and the second body to each other so that they can selectively approach each other and are separated from each other; a spring configured to be held on spring holding pins provided on opposite inner surfaces of the first grip portion and the second grip portion, and to impart elasticity between the first grip portion and the second grip portion; a shock-absorbing member provided on any one of the opposite inner surfaces of the first grip portion and the second grip portion, and configured to come into elastic contact with a remaining one of the opposite inner surfaces of the first grip portion and the second grip portion and then absorb an impact applied to a hand of an operator at a moment when the operator grips the first grip portion and the second grip portion, presses them inward and cuts off a branch or stem in order to cut off a tree branch; and a rubber elastic hanger member provided on any one of the opposite inner surfaces of the first grip portion and the second grip portion, and configured to enable the pruning shears to be hung on a tree branch within a work range of the operator in such a manner as to allow the tree branch to be pushed against it and to be held within a space inside it, characterized in that a stop depression is formed in the first cutting portion and an opening and closing lever configured to be struck in the stop depression through rotation is further provided on the second cutting portion so that rotation can be stopped in a state in which the first grip portion and the second grip portion have been pressed inward through gripping, and wherein the elastic hanger member is adapted to be bent in the direction of force when the tree branch pushes the elastic hanger member to be inserted between the first grip portion and the second grip portion. a first body configured to include a first cutting portion in which a plurality of first slip prevention depressions configured to prevent a slip during cutting of a tree branch is formed, on one side thereof, and a first grip portion which has a sliding portable saw accommodation means configured to cut off a tree branch or stem outside a cutting range of the pruning shears, on a remaining side thereof;
