The synchronous belt 2122 is arranged in transmission between the first synchronous wheel 2121 and the second synchronous wheel 2123, so that the rotation of the first synchronous wheel 2121 can drive the rotation of the second synchronous wheel 2123 through the synchronous belt 2122.

The second synchronous wheel 2123 at the bottom of the holder 2101 is arranged to penetrate the outer wall of the holder 2101 through a rotating shaft and is in transmission connection with the second rotating disc 2119, so that the rotation of the second synchronous wheel 2123 can drive the rotation of the second rotating disc 2119 through the rotating shaft.
[0036] The specific working process is as follows: Firstly, the wire harness is sleeved on the outer surfaces of the plurality of arc sleeves 2105, and then the double-shaft motor 2103 is started. The rotation of the double-shaft motor 2103 drives the rotation of the two first synchronous wheels 2121, the rotation of the first synchronous wheels 2121 drives the rotation of the second synchronous wheels 2123 through the synchronous belts 2122, and the rotation of the two second synchronous wheels 2123 drives the rotation of the first rotating disc 2117 and the second rotating disc 2119, respectively. Since the second sliding rod 2118 and the third sliding rod 2120 are slidably connected with the first sliding groove 2114 and the second sliding groove 2116, respectively, the rotation of the first rotating disc 2117 and the second rotating disc 2119 can drive the reciprocating movement of the first moving block 2113 and the second moving block 2115, respectively. The first moving block 2113 and the second moving block 2115 drive the reciprocating movement of the sliding sleeve 2107 and the first sliding rod 2108, respectively. Since the radius of the second rotating disc 2119 is greater than the radius of the first rotating disc 2117, the stroke of the sliding sleeve 2107 is greater than that of the first sliding rod 2108. When the first moving block 2113 moves to the maximum distance, the second sliding rod 2118 slides into the semicircular sliding groove of the first sliding groove 2114. Since the radius of the semicircular sliding groove of the first sliding groove 2114 is equal to the center distance between the second sliding rod 2118 and the first rotating disc 2117, the first moving block 2113 will stop moving at this time. Since the stroke of the sliding sleeve 2107 is greater than that of the first sliding rod 2108, the plurality of sliding sleeves 2107 will continue to move. Thus, the fixed ring 2112 drives the swinging of the first connecting rod 2110, thereby swinging the first connecting rod 2110 and the second connecting rod 2111 to drive the opening of the arc sleeves 2105, thereby fixing the wire harness. Then, the second sliding rod 2118 and the third sliding rod 2120 drive the arc sleeves 2105 to move to the side of the first moving block 2113 through the first moving block 2113, the first sliding rod 2108, the limiting table 2109, the second connecting rod 2111, the second moving block 2115, the sliding sleeve 2107, and the first connecting rod 2110. The arc sleeves 2105 drive the wire harness to move. When the first moving block 2113 moves to the maximum distance, the second sliding rod 2118 slides into the semicircular sliding groove of the first sliding groove 2114 again, and the first moving block 2113, the first sliding rod 2108, and the limiting table 2109 stop moving. Since the stroke of the sliding sleeve 2107 is greater than that of the first sliding rod 2108, the sliding sleeve 2107 continues to drive the swinging of the first connecting rod 2110, so that the plurality of arc sleeves 2105 are retracted to each other, thereby ending the fixation of the wire harness by the plurality of arc sleeves 2105, and achieving the step-by-step conveying of the wire harness. While conveying, the first stepping motor 2004 is started to drive the step-by-step conveying device 210 to rotate.Then the laser cutter 1004 is started, and the laser cutter 1004 cuts the rotating and moving wire harness, so that the cut of the wire harness is spiral, and because the material of the circular arc sleeve 2105 is copper, the high reflection and high thermal conductivity of copper can effectively block the cutting of the laser, and then the cut wire harness is wound on the take-up reel 2003, and the second stepping motor 2005 is started, and the second stepping motor 2005 drives the take-up reel 2003 to rotate, so as to wind the cut wire harness on the take-up reel 2003.
