The lower pressing block (27) can be plugged into the lifting block (26) and extend from the lifting block (26). A spring is provided inside the lifting block (26). The other end of the spring is connected to the end of the lower pressing block (27). The spring has a pushing force on the lower pressing block (27), so that the lower pressing block (27) extends from the inside of the lifting block (26).

8. A skeleton coil wire end shearing device according to claim 7, characterized in that: A plurality of groups of limit bars (30) are arranged inside the skeleton coil (2), and the positions of the limit bars (30) correspond to the positions of the through slots (23). The surface of the supporting block (31) is provided with limit slots (29), and the limit bars (30) can be inserted into the limit slots (29). When the bottom of the plug-in block (22) is inserted into the through slot (23), the second lifting rod (32) descends to drive the pressing block (27) to descend through the cross bar (24) and the transverse rod (25), and the bottom of the pressing block (27) is supported on the top of the plug-in block (22), so that the plug-in block (22) descends inside the rectangular plate (21).

9. A skeleton coil wire end shearing device according to claim 8, characterized in that: The swing plate (19) swings along with the rotating shaft on the surface so that the second clamping plate (17) and the first clamping plate (16) are clamped on the surface of the wire (4); the first clamping plate (16) and the second clamping plate (17) move along with the slider (8), and the ends of the first clamping plate (16) and the second clamping plate (17) move into the winding groove of the skeleton coil (2); the plug-in block (22) descends and is plugged into the slot (15) on the surface of the second clamping plate (17), and the wire (4) is pushed out from between the first clamping plate (16) and the second clamping plate (17) through the slot (15) on the surface of the first clamping plate (16).

10. A skeleton coil wire end shearing device according to claim 9, characterized in that: The width of the groove (15) on the surface of the second clamping plate (17) is smaller than the width of the groove (15) on the surface of the first clamping plate (16); the first clamping plate (16) is elastic; the width of the groove (15) on the surface of the first clamping plate (16) is smaller than the diameter of the wire (4); when the wire (4) is inserted into the groove (15) on the surface of the first clamping plate (16), the first clamping plate (16) can be deformed so that the width of the groove (15) increases.
