[0023] When in use, an external force is applied to the driving block 22, and the protrusion 220 abuts against the cutter 23, pushing the cutter 23 to move downward. The cutter 23 abuts against and compresses the elastic member 6 during the downward movement, and the fixing block 21 is pressed by the elastic member 6, thereby pressing the pins on both sides of the give way groove 12. The cutter 23 continues to move downward, passes through the through groove 211, and cuts the pins of the resistor 100.

[0024] Combination Figure 3 The driving block 22 is also provided with a guide rod 5, and a slider is provided on the guide rod 5. The two ends of the linkage rod 24 are respectively rotatably connected to the cutter 23 and the slider. The guide rod 5 is also sleeved with an elastic member 7, and the two ends of the elastic member 7 are respectively abutted against the driving block 22 and the slider. The elastic member 7 can push the slider to move along the guide rod 5, wherein the elastic member 7 can be a spring; after cutting the pins of the resistor 100, the elastic member 7 can push the slider, drive the cutter 23 to rotate out of the clearance groove 12, and lift it upward.

[0025] Combination Figure 2The fixing block 21 and the driving block 22 are respectively provided with clamping grooves 213 corresponding to the placement groove 11 at the bottom. When the pins of the resistor 100 are cut, the clamping grooves 213 are used to clamp and fix the pins of the resistor 100 on both sides of the placement groove 11 to prevent the pins of the resistor 100 from moving along the placement groove 11 when the pins are cut. An elastic rubber pad can be provided in the placement groove 11 to better fix the pins of the resistor 100.

[0026] Combination Figure 1 In order to facilitate the application of external force to the shearing mechanism 2, the pins of the resistor 100 can be cut more labor-savingly; a driving mechanism 3 is also provided on the base 1, and the driving mechanism 3 is rotatably connected to the shearing mechanism 2; specifically, the driving mechanism 3 includes a driving rod 31 and a pressure rod 32, the driving rod 31 is rotatably connected to the base 1, and at least one elastic member three 9 is provided at one end of the driving rod 31 and connected to the base 1, and the pressure rod 32 is rotatably connected to the driving rod 31 and the driving block 22, wherein the elastic member three 9 can be a spring or an elastic rubber strip, etc., and there are two elastic members three 9.

[0027] When in use, the driving rod 31 is rotated to drive the pressing rod 32 to press the shearing mechanism 2, so as to facilitate the shearing of the pins of the resistor 100 more conveniently and labor-savingly. During shearing, the elastic member 3 9 is in a stretched state. When the shearing mechanism 2 is in an idle state, the elastic member 3 9 can drive the driving rod 31 to lift the shearing mechanism 2 upward through its own elastic force, so as to facilitate the removal or placement of the resistor 100.

[0028] Combination Figure 4 In order to be able to cut out resistor 100 pins of various lengths, the base 1 is also provided with an adjustment mechanism 4, and the adjustment mechanism 4 is used to adjust the position of the shearing mechanism 2 on the base 1; specifically, the adjustment mechanism 4 includes a threaded rod 41 and an adjustment hand wheel 42, and a locking piece 43 arranged on the threaded rod 41, wherein the locking piece 43 can be a locking nut, the threaded rod 41 is screwed to the base 1, and the shearing mechanism 2 is rotatably connected to the threaded rod 41, and the adjustment hand wheel 42 is arranged at one end of the threaded rod 41. The position of the shearing mechanism 2 on the base 1 is adjusted by rotating the adjustment hand wheel 42, and the shearing mechanism 2 cooperates with the make way groove 12, so that pins of various lengths can be cut according to actual needs. The locking piece 43 is used to lock the threaded rod 41 after the adjustment is completed to prevent the threaded rod 41 from rotating during use, causing the position of the shearing mechanism 2 to shift.

[0029] Combination Figure 2The cutter 23 is provided with a rotating column 232 and a limiting column 231, the rotating column 232 is rotatably connected to the driving block 22 and the fixed block 21, and the driving block 22 and the fixed block 21 are both fixedly rotatably connected to the rotating column 232; the fixed block 21 is provided with a limiting groove 212, the limiting column 231 is slidably arranged in the limiting groove 212, and the limiting column 231 can limit the movement of the cutter 23 along the limiting groove 212.

[0030] After the shearing is completed, the driving mechanism 3 pulls up the driving block 22, the elastic member 7 pushes the slider, and the cutter 23 is pulled into the cavity 8 through the connecting rod 24. The limiting column 231 moves to the top of the limiting groove 212, abuts against the limiting groove 212 to drive the fixed block 21 to lift.

[0031] In actual use, the shearing mechanism 2 is in a raised state, and the resistor 100 is placed in the placement groove 11. When the shearing mechanism 2 is adjusted to a suitable position by the adjustment mechanism 4, the driving mechanism 3 is driven to drive the shearing mechanism 2 to move downward, and the fixed block 21 first contacts the pin of the resistor 100. When the protrusion 220 abuts the cutter 23, the cutter is driven to move downward along the limit groove 212. The cutter 23 abuts the elastic member 6, and an external force is applied to the fixed block 21 to press and fix the pin of the resistor 100. The cutter 23 continues to move downward through the through groove 211 and rotates to the corresponding give way groove 12. The shearing of the resistor 100 pin is completed, and the external force on the driving mechanism 3 is removed. The elastic member 3 9 pulls the shearing mechanism 2 to reset and lift it, which is convenient for removing the sheared resistor 100 or placing a new resistor 100.
