The various items in the embodiment are drawn according to the proportions, dimensions, amounts of deformation or displacements that are suitable for the description, rather than the proportions of the actual components. In the following description, similar elements are denoted by the same reference numerals. As shown in the first circle and the second circle, the present invention is a shearing tool capable of adjusting the cutting angle, comprising: a first shank 10, the first shank 10 having a locking piece at one end The cutting edge 12 is movably positioned thereon, and the first shank-end is provided with a first grip 201249618 13 ' for gripping and the first grip 13 is provided with an inwardly tapered recess a second shank 20, the first shank 10 and the second shank 20 are coupled by a plurality of teeth 101, 201, and are disposed on the side of the teeth 1 〇 1, 201 The connecting piece 21 is respectively connected to the first shank 10 and the second shank 20 at least one end, and a spring 22 is disposed between the first shank 1 〇 and the second shank 20 to enable the first a handle 1〇 cooperates with the second handle 2〇 movable; wherein the second handle 20 is provided with a second grip 23 for gripping the other end of the cutting edge 12, the first handle 23 A shank 231 is disposed on the inner side of the second handle 23 for the second shank 2, and the two ends of the second handle 23 are respectively connected by a shaft 232 and a lock 233 and the second handle. The rods 20 are connected to each other and to the handle The inner walls of the two sides of the 231 are respectively provided with an opening 234 and a slot 235 for receiving the 7712; the second handle 23 is also provided with a recess 24 which is tapered inwardly; a cobalt table 30 is active The lock is disposed on one end of the second shank 2 〇 relative to the cutting edge , to cooperate with the shearing 7712 to generate a shearing motion, wherein the miscellaneous 3Q is formed to extend to the side of the second shank 20- The secret (4) is provided with - minus & and the drill stand is combined with the side to form a - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - There are a plurality of positioning holes 33 in the concave portion of the stern near the sliding edge of the stern. The movable piece 40 is made of elastic material such as plastic, and is worn at one end. And a rotating shaft 41 in the shaft hole 31. The end of the rotating shaft 41 is provided with a larger diameter locking end 411 ', and the rotating shaft 41 is provided with at least an elastic groove 412, so that the rotating shaft 41 can be elasticized. The cymbal is retracted to penetrate into the shaft hole 31, and the rotation end of the shaft is prevented from being disengaged by the setting of the locking end 411, and the other end of the 纠4Q is provided with the hooking at the riding edge 32. 201249618 The slot 42 is configured such that the movable flap 40 can be pivoted on the rig 30 and adjusts the relative angle between the movable flap 40 and the cutting edge 12; and a positioning clip 50 is disposed on the movable block. The locating clip 50 and the movable dam 40 are provided with an elastic member 51 so that the locating clip 50 is elastically clamped at the bottom side of the rig 30, and the locating clip 50 has an movable portion. The positioning end 52 is embedded in the positioning hole 33. After the above structure is clarified, the following is a detailed description of the operation and principle of the present invention. As shown in the third figure, when the user wants to change the cutting angle, the positioning clip 50 may be pressed first to make the positioning end 52. Separating from the positioning hole 33, the movable blocking piece 40 is in a movable rotating state, so as to force the one end of the fitting groove 42 to slide along the sliding edge 32 to a predetermined angle, and then release the positioning clip. 50, by the elastic force of the elastic member 51, the positioning end 52 is re-inserted in the positioning hole 33 (as shown in the fourth figure). The positioning holes 33 are disposed at a common angle for facilitating rapid adjustment. Even if the positioning holes 33 are not properly positioned at a predetermined angle, the movable blocking piece 40 can be fixed to the movable blocking piece 40 by the clamping force of the positioning clips 50. At a predetermined angle. As shown in the fifth and sixth figures, when the relative angle between the movable flap 4 and the cutting edge 12 is changed to a predetermined cutting angle, the working member can be abutted against the movable flap 40, and then pressed. The first grip 13 and the second grip 23 are combined to cut the cutting edge 12 at the drill floor 30 and form a predetermined angle. The coupling of the teeth 101, 201 can reduce the force required for the user to cut the work piece, and the design of the recesses 14, 24 can further improve the grip of the palm of the hand. As shown in the seventh figure, the present invention can perform the dismounting operation of the cutting edge 12 only after the locking piece 1彳 is removed, and the locking member 233 on the second grip 23 can be removed. The second grip 23 6 201249618 can be rotated and rotated by the shaft 232 so that the edge groove 235 in the shank 23 is exposed outside the second shank 20, so that the preparatory cutting edge stored in the cutting edge 235 12 can be taken out from the opening 234 for replacement work; or when the cutting tool is not in use, the cutting edge 12 is removed and placed in the cutting edge groove 235 for storage, when the second grip 23 is returned to the original position and locked After the fastener 233 is locked, the blade groove 235 is blocked by the second shank 20 to surely prevent the stored cutting edge 12 from accidentally falling out.
