[0062] The shell 100 is provided with a limiting block 110 matched with the fastening pawl 320, and the fastening pawl 320 has two states relative to the limiting block 110.

[0063] When the fastening pawl 320 abuts against the limiting block 110, the cable tie can be fed and moved relative to the fastening pawl 320.

[0064] When the fastening pawl 320 is separated from the limiting block 110, the fastening pawl 320 fastens the cable tie.

[0065] The fastening connecting rod 310 is provided with a plurality of sliding rods 312, and the shell 100 is provided with a fastening sliding groove 140 matched with the sliding rods 312. The fastening connecting rod 310 moves along the length direction of the fastening sliding groove 140 through the sliding rods 312, and the other end of the fastening connecting rod 310 is connected with the driving rod 520 through the connecting rod 530.

[0066] In addition, the connecting rod 530 is connected with the fastening connecting rod 310 through the sliding rod 312.

[0067] The outer side of the arm rod 540 is further provided with a fixed plate 550, one end of the fixed plate 550 is connected with the arm rod 540 through a rotating shaft and is connected with the driving rod 520, and the other end of the fixed plate 550 is positioned and connected with the shell 100. The fixed plate 550 ensures the smoothness and stability of the whole connecting rod assembly 500 during movement.

[0068] The cutting connecting rod 410 is provided with a cutting positioning shaft 411, and the shell 100 is provided with a cutting positioning hole 120 matched with the cutting positioning shaft 411. The cutting connecting rod 410 can rotate along the axial direction of the cutting positioning shaft 411 to realize the cutting of the cable tie.

[0069] As mentioned above, the driving rod 520 is connected with the arm rod 540 through a rotating shaft, and the arm rod 540 is connected with the cutting connecting rod 410 through a rotating shaft. Therefore, the whole cutting process of the cable tie is as follows:

[0070] When the cable is tightened, the position of the fastening connecting rod 310 will not change, the motor 210 drives the guide rod 220 to continue to rotate, at this time the connecting rod 530 and the driving rod 520 pivot connection as a lever, the driving rod 520 rotates along the axis of the connecting rod 530 and the driving rod 520 pivot, the driving rod 520 rotates to drive the arm rod 540 to rotate, and then the arm rod 540 transmits the external force to the cutting connecting rod 410, the cutting connecting rod 410 rotates along the axis of the cutting positioning shaft 411 to drive the blade 420 to cut the cable. In this process, the cutting positioning shaft 411, the driving rod 520 and the connecting rod 530 pivot as a lever to achieve the entire cutting process.

[0071] The connection between the driving rod 520 and the arm rod 540 is provided with a reset mechanism, the reset mechanism includes a link block 610 connected to the connection between the driving rod 520 and the arm rod 540, the link block 610 is provided with two shafts and includes a link positioning shaft 611 and a link sliding shaft 612, the shell 100 is provided with a link positioning hole 130 and a link sliding groove 170 for use of the link positioning shaft 611 and the link sliding shaft 612;

[0072] The link sliding shaft 612 is connected to the tension adjusting mechanism 600 through a bracket 620.

[0073] Since the link block 610 is connected to the connection between the arm rod 540 and the driving rod 520, when the position of the arm rod 540 and the driving rod 520 changes, one end of the link block 610 is always connected to the connection between the arm rod 540 and the driving rod 520, and the link block 610 rotates along the axis of the link positioning shaft 611, during the rotation, the link sliding shaft 612 moves along the length direction of the link sliding groove 170 of the shell 100, and then moves relative to the tension adjusting mechanism 600 through the bracket 620.

[0074] The tension adjusting mechanism 600 includes an adjusting rod 630 provided in the shell 100 through a fixing sleeve 640, the adjusting rod 630 is connected to a knob 650 through the bracket 620, a spring 631 is arranged between the adjusting rod 630 and the bracket 620, and the adjusting rod 630 is rotated to adjust the tension of the spring 631 through the knob 650.

[0075] During the entire process, the position of the adjusting rod 630 will not change unless the tension of the spring 631 is adjusted through the knob 650; when the bracket 620 moves relative to the adjusting rod 630, the spring 631 between the bracket 620 and the adjusting rod 630 will be compressed or reset.

[0076] The change of the position of the adjusting rod 630 affects the tension of the spring 631 between the adjusting rod 630 and the bracket 620, and then affects the entire cutting process and the tightening process.

[0077] According to different scenarios of the application of the cable tie, the tightness of the spring 631 is adjusted by the knob 650, and then the tightness of the cable tie is adjusted.

[0078] When there is a cable tie, the cable tie gun idles, the transmission rod 510 is provided with a guide block, and the shell 100 is provided with a guide groove 150 matched with the guide block. When the motor 210 starts, the transmission rod 510 reciprocates along the length direction of the guide groove 150.

[0079] The force for moving the fastening connecting rod 310 passes through the guide rod 220, the transmission rod 510, the drive rod 520, and the connecting rod 530 in sequence, and finally reaches the fastening connecting rod 310, driving the fastening connecting rod 310 to move.

[0080] In this process, the fastening connecting rod 310 always reciprocates, the position of the adapter block 610 does not change, and then the adapter block 610 does not drive the bracket 620 to move relative to the adjusting rod 630, and the tension of the spring 631 does not change.

[0081] When there is a cable tie, the force for moving the fastening connecting rod 310 passes through the guide rod 220, the transmission rod 510, the drive rod 520, and the connecting rod 530 in sequence, and finally reaches the fastening connecting rod 310, driving the fastening connecting rod 310 to move.

[0082] In this process, the drive rod 520 slightly rotates, and in the rotating process, the adapter block 610 is driven to rotate by the drive rod 520, and the bracket 620 is driven to move relative to the adjusting rod 630 by the adapter block 610 through the adapter sliding shaft 612. When the tension of the cable tie reaches the value adjusted by the knob 650, the movement of the bracket 620 relative to the adjusting rod 620 stops, and due to the above-mentioned connection relationship, the fastening connecting rod 310 cannot move again.

[0083] In addition, when the motor 210 continues to rotate, in the rotating process, the adapter block 610 is driven to rotate by the drive rod 520, and the bracket 620 is driven to move relative to the adjusting rod 630 by the adapter block 610 through the adapter sliding shaft 612. At this time, the force applied by the motor 210 has exceeded the value set by the knob 650, so the cutting process is directly entered. The amplitude of the rotation of the drive rod 520 is increased to drive the arm rod 540 to move, and then the cutting of the cable tie is completed.

[0084] In combination with the above-described cable cutting process, when the adapter block 610 rotates along the adapter positioning shaft 611, the support 620 moves relative to the adjusting rod 630, thereby compressing the spring 631 between the support 620 and the adjusting rod 630; after the cable cutting is completed, the spring 631 is used again to reset the adapter block 610, thereby resetting the blade 420. The entire resetting process and the external force transmission process during cutting are similar, except that the adapter block 610 moves the driving rod 520, thereby rotating the arm rod 540 through the driving rod 520.

[0085] The locking block 700 is further provided on the housing 100 through the torsion spring shaft assembly, one end of the locking block 700 abuts against the adapter block 610, the other end of the locking block 700 is provided with a driving tooth 710, the end of the fastening connecting rod 310 is provided with a rack 313 used in cooperation with the driving tooth 710, the driving tooth 710 is engaged with the rack 313 to fix the fastening connecting rod 310.

[0086] The housing 100 is provided with a locking positioning hole 160 used in cooperation with the torsion spring shaft assembly.

[0087] During the cutting process, since the adapter block 610 rotates along the adapter positioning shaft 611, and one end of the locking block 700 always abuts against the adapter block 610, the torsion spring of the locking block 700 is always in a compressed state during this process. When the adapter block 610 rotates, the locking block 700 also rotates through the spring 631 of the torsion spring. Finally, the driving tooth 710 provided on the locking block 700 is engaged with the rack 313 of the fastening connecting rod 310, thereby avoiding the position change or component shaking of the fastening connecting rod 310 due to the loss of the tensioning force of the cable at the moment of cable cutting.

[0088] When the cutting is completed and the blade 420 enters the resetting action, the locking block 700 is rotated through the adapter block 610. During the rotation process, the driving tooth 710 is separated from the rack 313, thereby enabling the fastening connecting rod 310 to move again.

[0089] The fastening connecting rod 310 is provided with a pawl guard 311 used in cooperation with the fastening pawl 320.
