[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] like Figures 1-4 As shown, the present invention proposes a foreign object removal device, including a sleeve A1, a sleeve B3 snapped onto the sleeve A1, and a handle 2 fixedly connected to one side of the sleeve B3. The sleeves A1 and B3 are internally provided with a gripping assembly 4 for gripping foreign objects. The gripping assembly 4 includes a foreign object fixing clamp 404 hinged inside the sleeve A1 and a connecting rod 407 fixedly connected to one side of the foreign object fixing clamp 404. A telescopic spring 405 is provided inside the foreign object fixing clamp 404. The gripping assembly 4 also includes a handle hinged to the foreign object fixing clamp 404. The clamping assembly 4 includes a fixing block 406 on one side and a clamping plate 403 fixedly connected to the other side of the foreign object clamping clamp 404. The other side of the fixing block 406 is fixedly connected to the connecting rod 407. The clamping assembly 4 also includes a telescopic spring A402 sleeved on the outside of the connecting rod 407 and a pressing block 401 fixedly connected to one side of the connecting rod 407. The connecting rod 407 extends to the outside of the sleeve B3, and the telescopic spring A402 is located outside the sleeve B3, thereby achieving the effect of removing and replacing the sleeve A1 and the sleeve B3 and replacing the foreign object clamping clamp 404 at regular intervals.

[0026] In this embodiment: when it is necessary to remove a foreign object, the worker presses the pressing block 401. The pressing block 401 compresses the telescopic spring A402, which in turn moves the connecting rod 407. The connecting rod 407 moves the telescopic spring B405, which in turn moves the foreign object fixing clamp 404. The foreign object fixing clamp 404 moves the clamping plate 403, and extends. Under the reaction force of the telescopic spring 405, the two foreign object fixing clamps 404 open, and the foreign object enters between the foreign object fixing clamps 404. When the pressing block 401 is released, the foreign object fixing clamps 404 move in the opposite direction, thereby achieving the effect of clamping the foreign object.

[0027] Example 2

[0028] like Figures 1-4 As shown, based on Embodiment 1, a snap-fit ​​assembly 5 for disassembly is provided between sleeve A1 and sleeve B3. The snap-fit ​​assembly 5 includes a circular slide plate 502 slidably connected to the top of sleeve A1, a compression groove 503 and two slots 508 formed in the circular slide plate 502, two hooks 512 fixedly connected to the bottom of sleeve B3, and a compression hook 504 slidably connected to one side inside sleeve B3. The two hooks 512 and the compression hook 504 are all distributed in a ring. The snap-fit ​​assembly 5 also includes a slide groove 506 set at the top of sleeve A1 and a fixing plate 505 fixedly connected to the inside of the slide groove 506. Pressure springs A507 are fixedly connected to both sides of the fixing plate 505. Both sides of the two pressure springs A507 are fixedly connected to the circular slide plate 502, thereby achieving the effect of disassembly between sleeve A1 and sleeve B3.

[0029] In this embodiment: when the worker wants to remove the foreign object fixing clip 404, he presses the pressing rod 509. The pressing rod 509 causes the pressure spring B511 to contract, and at the same time causes the squeezing hook 504 to move downward. The squeezing hook 504 squeezes the squeezing groove 503. The squeezing groove 503 causes the circular sliding plate 502 to move inside the sliding groove 506. The two hooks 501 disengage from the two slots 508, and the foreign object fixing clip 404 is removed, thereby achieving the disassembly and removal effect between the sleeve A1 and the sleeve B3.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
