[0036] In the specific, when the corrugated sleeve 2 needs to be stretched, the elastic force of the first elastic member 5 makes the inner arc plate 3 move out from the inside of the inner groove 401 until the inner concave surface of the inner arc plate 3 is attached to the circumferential outer side surface of the laser head 1, the pushing component makes the outer frame 4 move away from the workpiece 14, the moving outer frame 4 drives the inner arc plate 3 to move synchronously through the rotating component until the outer frame 4 is outside the ring groove 101, at this time the inner arc plate 3 corresponds to the ring groove 101, the elastic force of the first elastic member 5 makes the inner arc plate 3 move to the inside of the ring groove 101, the inner arc plate 3 pulls the connecting rod of the rotating component 9, at this time the rotating component 9 rotates, the rotating component 9 makes the convex rod 10 slide in the arc-shaped groove 11, the distance between the two rotating components 9 gradually decreases until the inner concave surface of the inner arc plate 3 is attached to the inner side wall of the ring groove 101.

[0037] When the corrugated sleeve 2 needs to be contracted, the convex rod 10 is pushed to move in the arc-shaped groove 11, the distance between the two rotating components 9 gradually increases, the rotating rotating component 9 makes the inner arc plate 3 move out from the inside of the ring groove 101, the inner arc plate 3 extrudes the first elastic member 5 in the process of moving out, until the inner arc plate 3 moves to the inside of the inner groove 401 of the outer frame 4, when the outer frame 4 approaches the workpiece 14 through the pushing component, the outer frame 4 extrudes the corrugated sleeve 2, the tension on the convex rod 10 is released, the elastic force of the first elastic member 5 makes the inner concave surface of the inner arc plate 3 attached to the circumferential outer side surface of the laser head 1 until the outer frame 4 cannot continue to approach the workpiece 14.

[0038] In the embodiment, the pushing component makes the outer frame 4 outside the ring groove 101, the first elastic member 5 cooperates with the rotating part to make the inner arc plate 3 clamped inside the ring groove 101, and the outer frame 4 cooperates with the corrugated sleeve 2 to protect the laser head 1. At this time, the protection device corresponds to the protection of the laser head 1, and direct impact of external components on the surface of the laser head 1 is avoided. When the laser head 1 is damaged, the pushing component makes the outer frame 4 extrude the corrugated sleeve 2 until the outer frame 4 cannot continue to approach the working piece 14, so that the laser head 1 is conveniently replaced. When the new laser head 1 is installed on the front side of the working piece 14, the pushing component pulls the corrugated sleeve 2 by the outer frame 4, and the locking component makes the outer frame 4 continue to lock outside the laser head 1.

[0039] In order to protect the front side end of the laser head 1, the buffer device is used to protect the laser head 1. Figure 1 、 Figure 2 、 Figure 5 and Figure 7 , the buffer device comprises: a sleeve ring 12 and a second elastic member 13, the second elastic member 13 is provided as a spring, the outer frame 4 is provided with a first side edge 402 on the outer convex surface, the first side edge 402 is provided with a moving rod 403 penetrating through the top and the bottom, the moving rod 403 is provided with a second side edge 121 on the front side end, and the second side edge 121 is installed on the outer convex surface of the sleeve ring 12.

[0040] Specifically, when the locking component makes the outer frame 4 lock outside the laser head 1, at this time, the elastic force of the second elastic member 13 makes the sleeve ring 12 away from the working piece 14, until the front side of the sleeve ring 12 is located in front of the front side of the laser head 1, and the laser cleaning head is placed on the top surface of the workbench by hand. At this time, the front side end of the laser head 1 may impact on the top surface of the workbench, and the reaction force of the top surface of the workbench on the sleeve ring 12 makes the sleeve ring 12 close to the working piece 14.

[0042] Working principle of the application:

[0043] Refer to Figures 1 to 7As shown, the rotating circular plate drives the rotating rod 6 to rotate inside the moving groove 181. Since the rotating rod 6 spirally penetrates the outer side of the movable frame 7, the rotating rod 6 drives the movable frame 7 to move horizontally inside the moving groove 181. The movable frame 7 drives the outer frame 4 to move outside the laser head 1 through the connecting piece 8.

[0044] When the laser head 1 is damaged, the convex rod 10 is pushed to move inside the arc-shaped groove 11. The distance between the outer side ends of the two rotating frames 9 gradually increases. The rotating frame 9 drives the inner arc plate 3 to move out of the ring groove 101. The inner arc plate 3 extrudes the first elastic member 5 during the moving-out process. When the outer frame 4 is close to the working member 14 through the pushing component, the outer frame 4 extrudes the corrugated sleeve 2. The tension on the convex rod 10 is released. The elastic force of the first elastic member 5 makes the inner concave surface of the inner arc plate 3 fit the circumferential outer side surface of the laser head 1. When the new laser head 1 is installed on the front side of the working member 14, the pushing component pulls the corrugated sleeve 2 through the outer frame 4. The outer frame 4 is continuously locked outside the laser head 1 through the locking component.

[0045] When the laser head 1 needs to be protected, the elastic force of the first elastic member 5 makes the inner arc plate 3 move out of the inner groove 401. The inner concave surface of the inner arc plate 3 fits the circumferential outer side surface of the laser head 1. The outer frame 4 is moved away from the working member 14 through the pushing component. The moving outer frame 4 drives the inner arc plate 3 to move synchronously through the rotating part. When the outer frame 4 is outside the ring groove 101, the inner arc plate 3 corresponds to the ring groove 101. The elastic force of the first elastic member 5 makes the inner arc plate 3 move into the ring groove 101. The inner arc plate 3 pulls the connecting rod of the rotating frame 9. At this time, the rotating frame 9 rotates. The rotating frame 9 makes the convex rod 10 slide inside the arc-shaped groove 11. The distance between the outer side ends of the two rotating frames 9 gradually decreases. The inner concave surface of the inner arc plate 3 fits the inner side wall of the ring groove 101.

[0046] When the pushing component makes the outer frame 4 outside the ring groove 101, the first elastic member 5 cooperates with the rotating part to make the inner arc plate 3 clamped inside the ring groove 101. The outer frame 4 cooperates with the corrugated sleeve 2 to protect the laser head 1. At this time, the protection device corresponds to the protection of the laser head 1 to avoid the direct impact of external components on the surface of the laser head 1.

[0047] The workpiece to be cleaned is placed on the workbench, the handgrip 15 is held, the front end of the laser head 1 is aligned with the workpiece, the button 16 is pressed, the power supply device supplies power to the workpiece 14 through the wire 19, and the workpiece 14 irradiates laser on the surface of the workpiece through the front end of the laser head 1, so that the machining pattern forms a circle. The laser head 1 is moved by the handgrip 15, so that the entire workpiece can be quickly and conveniently cleaned by laser. After the workpiece is cleaned, the workpiece 14 is placed on the workbench by the side plate 18, the laser head 1 is protected by the side plate 18, and the laser head 1 is prevented from directly impacting on the workbench.

[0048] After the cleaning of the workpiece is completed, the entire laser cleaning head is placed on the top surface of the workbench by hand, the front end of the laser head 1 may impact on the top surface of the workbench, at this time, the reaction force of the top surface of the workbench on the sleeve ring 12 makes the sleeve ring 12 close to the workpiece 14, and the moving sleeve ring 12 extrudes the second elastic member 13 by the second side edge 121, so that the laser head 1 is protected.
