It should be understood that in some embodiments, the distance adjusting mechanism 2 may only include a distance adjusting mobile station 22, and the screw micrometer 231 and the guide post 232 are connected to the fixed blade set 11 to change the relative position between the integrated circuit 100 and the fixed blade set 11 carried on the distance adjusting mobile station 22, so as to adjust the cutting length of the pins.
A notch (not shown) is disposed on the distance-adjusting mobile station 22 and corresponds to the upper portion of the placement portion 3, more specifically, a second mounting portion 226 is fixed on the table surface of the placement station 31, and the notch is correspondingly disposed on the second mounting portion 226 and corresponds to the upper portion of the placement portion 3. A circuit board 6 is fixed on the notch, for fixing the integrated circuit 100 and limiting the shortest dimension of the integrated circuit 100 after cutting the pins, wherein the shortest dimension is the length from the circuit board 6 to the edge of the first cutting plane 112b when the first concave surface 221a is attached to the corresponding surface of the fixed knife set 11 and the second concave surface 223a is attached to the corresponding surface of the distance-adjusting fixing plate 431, and the shortest dimension is the smallest dimension of the cutting tool capable of realizing processing. A gap for the pins of the integrated circuit 100 to pass through is formed between the circuit board 6 and the table board at the corresponding position of the distance-adjusting mobile station 22, and the gap is the clipping window 32.
The second mounting portion 226 is disposed on a side facing away from the shearing mechanism 1 and above the circuit board 6, and a protection plate 7 is further disposed on the second mounting portion to prevent an operator from touching the moving blade 122 or the blade of the fixed blade 112 during cutting of the bar.

When the application works, firstly, according to the shearing requirement of the pin length, the screw micrometer 231 is rotated, so that the thimble 231a extends out to push the distance-adjusting movable table 22 away from the distance-adjusting fixed table 21, and the distance between the distance-adjusting movable table 22 and the distance-adjusting fixed table 21 is adjusted to a required position; then, the integrated circuit 100 to be sheared is placed on the placing table 31 to be abutted against the circuit board 6, and the integrated circuit 100 is held by hand to be fixed, and the pins are flatly placed on the first shearing face 112b through the shearing window; then, the controller 51 steps down the foot switch 54, the controller 51 detects that the foot switch 54 is closed, the two-position five-way valve 52 is controlled to drive the push rod 421 of the reciprocating cylinder 42 to move downwards, the movable knife 122 is driven to be close to the fixed knife 112 downwards, pins exceeding the edge of the first shearing surface 112b are cut off under the cooperation of the first shearing surface 112b and the second shearing surface, broken pin scraps exit the shearing knife through the material returning groove 113 and the inclined plane, meanwhile, the cylinder magnetic switch 53 detects the position of the push rod 421 in the descending process of the push rod 421, the action is stopped when the push rod 421 descends to the lower limit, the cylinder magnetic switch 53 sends a feedback signal to the controller 51, and the controller 51 controls the two-position five-way valve 52 to drive the push rod 421 of the reciprocating cylinder 42 to move upwards according to the feedback signal, and the movable knife 122 is driven to be far away from the fixed knife 112; finally, the finished integrated circuit 100 may be removed from the placement unit 3.
After the cutting is completed, if other pins of the integrated circuit 100 need to be cut again according to the length, only the cutting operation is needed to be repeated; if other lengths are required to be sheared, the distance between the distance-adjusting movable table 22 and the distance-adjusting fixed table 21 is required to be adjusted to the required width, and then shearing operation is performed, so that a specific cutter is not required to be replaced in the whole process, and the device is simple in structure and convenient to operate.
