The main body has a first side, a second side, and a through hole communicating the first and the second sides, wherein the through hole can be passed through by the covering material. The blade is provided corresponding to the second side, and can be moved back and forth. The blade has a cutting edge, which passes over the through hole as the blade slides, whereby to cut off a part of the covering material beyond the second side. The elastic holding member is provided corresponding to the through hole to maintain the covering material at a predetermined position for cutting. ## Claims ### Claim 1 A cutting module of a cutting machine for trimming a window covering, wherein the window covering comprises a covering material; comprising: a main body, wherein the main body has two opposite sides, which are a first side and a second side, respectively; the main body has a through hole communicating the first side and the second side, wherein the through hole is adapted to be passed through by the covering material of the window covering; a blade, which has a cutting edge, wherein the blade is provided corresponding to the second side of the main body, and is movable back and forth along a sliding path; the cutting edge passes over the through hole as the blade slides, and therefore is adapted to cut off a part of the covering material beyond the second side when the covering material passes through the through hole; and an elastic holding member, which is provided corresponding to the through hole, and is adapted to exert an elastic force on the covering material when the covering material passes through the through hole to be trimmed, whereby to maintain the covering material at a predetermined position where the covering material does not contact at least a wall of the through hole; wherein the elastic holding member has two elastic plates which are adapted to provide the elastic force to the covering material passing through the through hole by being deformed, whereby to maintain the covering material at the predetermined position; wherein the two elastic plates are provided on the first side of the main body on opposite sides of the through hole, respectively, to provide the elastic force on opposite sides of the covering material, wherein the elastic plates are configured to deform by the covering material toward the blade. ### Claim 2 (depends on 1) The cutting module of claim 1, wherein the elastic holding member is provided on the main body, and is adapted to maintain the covering material passing through the through hole at the predetermined position. ### Claim 3 (depends on 1) The cutting module of claim 1, wherein the cutting edge has two corresponding chamfers; when the elastic holding member maintains the covering material at the predetermined position, and when the blade slides and the cutting edge passes over the through hole, the chamfers of the cutting edge are adapted to cut out two corresponding chamfers on the covering material. ### Claim 4 (depends on 1) The cutting module of claim 1, wherein the predetermined position of the covering material maintained by the elastic holding member refers to a centered position in a predetermined direction of the through hole. ### Claim 5 (depends on 4) The cutting module of claim 4, wherein the predetermined direction is perpendicular to the sliding path of the blade. ### Claim 6 (depends on 1) The cutting module of claim 1, wherein the elastic holding member is provided on the first side of the main body. ### Claim 7 (depends on 1) The cutting module of claim 1, wherein the side on which one of the two elastic plates is provided on the main body is an upper side of the through hole, while the side on which the other one of the two elastic plates is provided is a lower side of the through hole. ### Claim 8 (depends on 1) The cutting module of claim 1, wherein the two elastic plates are deformed as being bent from the first side of the main body toward the second side thereof. ### Claim 9 (depends on 8) The cutting module of claim 8, wherein, when the two elastic plates are deformed, a top end of each of the elastic plates does not exceed the second side of the main body through the through hole. ### Claim 10 (depends on 9) The cutting module of claim 9, wherein a shortest distance between the top end of each of the elastic plates and the second side of the main body in a direction from the first side to the second side is defined as a first length, and a depth of the through hole communicating the first side and the second side of the main body is defined as a second length; when the cover material passes through the through hole, the first length is less than or equal to the second length. ### Claim 11 (depends on 1) The cutting module of claim 1, wherein the two elastic plates are made of silicone rubber.
