[0030] In the scheme designed in the application, when it is needed to disengage the limiting insertion column 63 from the positioning insertion slot 621, the operator at this time sequentially counterclockwise pushes the push sliding assembly 7 in the swing groove, so that it can drive the limiting insertion column 63 to slide out of the positioning insertion slot 621 and shrink into the sliding guide groove, thereby facilitating the disengagement of the vertical insertion strip 61 and the arc-shaped insertion strip 62 from the T-shaped insertion slot 41; and when the vertical insertion strip 61 and the arc-shaped insertion strip 62 are completely inserted into the T-shaped insertion slot 41, the push sliding assembly 7 in the swing groove is clockwise pushed at this time, so that it drives the limiting insertion column 63 in the sliding guide groove to slide and insert into the aligned positioning insertion slot 621, thereby enabling the plurality of limiting insertion columns 63 to limit and fix the arc-shaped insertion strip 62 inserted into the T-shaped insertion slot 41, preventing the arc-shaped insertion strip 62 and the vertical insertion strip 61 from axially horizontally sliding in the T-shaped insertion slot 41.

[0031] As an embodiment of the application, the push sliding assembly 7 comprises an elastic cavity capsule 71, a flow guide hose 72, a cavity telescopic strip 73, an oval strip 74 and a rotating column 75. The top wall of each swing cavity 43 is provided with an elastic cavity capsule 71. The top end surface of each elastic cavity capsule 71 is fixedly connected with the upper cavity wall of the swing cavity 43, and the two side walls of the elastic cavity capsule 71 are in sliding contact with the cavity wall of the swing cavity 43. The side wall of the elastic cavity capsule 71 corresponding to the sliding guide groove 42 is communicated with the flow guide hose 72. The sliding guide groove 42 cut into two sections is provided with a cavity telescopic strip 73, and the open end of the cavity telescopic strip 73 is communicated with the flow guide hose 72.

[0032] In the scheme designed in the application, when the limiting plug 63 located in the sliding guide groove 42 needs to be slidingly inserted into the aligned positioning slot 621, at this time the maintenance personnel rotates the rotating column 75 located at the end opening of the swing cavity 43 to drive the oval strip 74 to rotate clockwise in the swing cavity 43, and the rotating of the vertical oval strip 74 will extrude the elastic cavity bag 71 at the top of the swing cavity 43, so that the gas or liquid medium filled in the elastic cavity bag 71 can enter into the cavity expansion strip 73 on both sides through the flow guide hose 72, and the medium filled in the cavity expansion strip 73 will make it expand in the sliding guide groove 42, and the expanded cavity expansion strip 73 will push the head of the limiting plug 63 in the sliding guide groove 42 to fill into the positioning slot 621, and a section of the tail of the limiting plug 63 will remain in the sliding guide groove 42, so that multiple limiting plugs 63 on the same side can be synchronously inserted into the side of the arc-shaped insertion strip 62, thereby achieving the effect of axially and horizontally limiting the sliding of the vertical insertion strip 61 and the arc-shaped insertion strip 62 inserted into the T-shaped slot 41, preventing the outer roller sleeve 5 from slightly axially and horizontally sliding on the inner roller column 4 when the polar piece is rolled by the assembled roller body 2, and when the limiting plug 63 needs to be separated from the positioning slot 621, at this time the rotating column 75 is counterclockwise rotated to make the oval strip 74 rotate counterclockwise in the swing cavity 43 to be horizontally separated from the extrusion of the elastic cavity bag 71, and the elastic restoring force of the supporting spring in the elastic cavity bag 71 will make it expand in the swing cavity 43, thereby the medium filled in the cavity expansion strip 73 will be drawn back, and the elastic restoring force of the elastic member in the cavity expansion strip 73 will drive it to shrink in the sliding guide groove 42, thereby facilitating the sliding shrink of the limiting plug 63 at the end thereof into the sliding guide groove 42, and the head of the limiting plug 63 can be withdrawn from the positioning slot 621, thereby facilitating the axial and horizontal separation of the vertical insertion strip 61 and the arc-shaped insertion strip 62 from the T-shaped slot 41. As an embodiment of the application, the pushing and sliding assembly 7 further comprises a limiting block 76, which is arranged in the swing cavity 43 and located below the right side of the elastic cavity bag 71. In the scheme designed in the application, in order to avoid the frequent rotation of the oval strip 74 in the swing cavity 43 from causing the continuous extrusion of the elastic cavity bag 71, when the rotating column 75 drives the oval strip 74 to rotate clockwise in the swing cavity 43 to extrude the elastic cavity bag 71, at this time the oval strip 74 is vertically rotated, and the top end of the oval strip 74 will contact the limiting block 76 arranged below the right side of the elastic cavity bag 71, thereby the limiting block 76 can block the limiting of the oval strip 74, preventing the continuous rotation of the oval strip 74 in the swing cavity 43 from causing the continuous extrusion of the elastic cavity bag 71.

[0033] As an embodiment of the present application, the front end of each of the plurality of swing cavities 43 is provided with a rotating locking assembly 8, the rotating locking assembly 8 comprises a blocking block 81, an internally threaded pipe 82 and a locking screw 83, the front end of each of the plurality of swing cavities 43 is fixed with a blocking block 81, and a rotating column 75 is rotatably connected to each blocking block 81, the internally threaded pipe 82 is connected to the end of the rotating column 75, and the internally threaded pipe 82 is located in the port of the swing cavity 43, a plurality of threaded holes 641 are arranged in the circumferential direction on the blocking disc 64, and each threaded hole 641 is aligned with the port of the internally threaded pipe 82, and the end of the plurality of locking screws 83 is connected to the internally threaded pipe 82 through the threaded hole 641;

[0034] In the design scheme of the present application, in order to facilitate the rotation of the elliptical strip 74 to the vertical state for fixation, prevent the self-rotation of the elliptical strip 74 in the swing cavity 43 when the roller body 2 rolls the pole piece, when the blocking disc 64 is sleeved on the transmission shaft 3, the blocking block 81 can block and support the elliptical strip 74 and the rotating column 75 in the swing cavity 43, at this time, the plurality of threaded holes 641 arranged on the blocking disc 64 are aligned with the ports of the internally threaded pipes 82 arranged in the plurality of swing cavities 43, then the blocking disc 64 is fixed by the snap spring 65, then the external hexagonal or internal hexagonal locking screw 83 is inserted into the threaded hole 641 in sequence, the locking screw 83 is rotated, and the locking screw 83 is continuously rotated into the internally threaded pipe 82, when the locking screw 83 is just rotated into the internally threaded pipe 82, the rotating column 75 is driven to rotate by the internally threaded pipe 82, so that the elliptical strip 74 is rotated to the vertical state to press the elastic cavity bag 71, when the elliptical strip 74 rotates and abuts against the limiting block 76, the rotating screw is continuously rotated, the rotating screw continuously enters the internally threaded pipe 82, and the elliptical strip 74 rotated to the vertical state is connected to the blocking disc 64 through the rotating column 75, the internally threaded pipe 82 and the locking screw 83, so as to fix the elliptical strip 74, and the self-rotation of the elliptical strip 74 in the swing cavity 43 is prevented; when the outer roller sleeve 5 needs to be disassembled, the locking screw 83 is counterclockwise at this time, when the locking screw 83 is counterclockwise, the rotating column 75 is first driven to rotate by the internally threaded pipe 82, so that the elliptical strip 74 in the swing cavity 43 is rotated to the horizontal state to separate from the pressing of the elastic cavity bag 71, at this time, the counterclockwise end face of the elliptical strip 74 abuts against the limiting block 76, therefore, with the continuous rotation of the locking screw 83, the locking screw 83 is separated from the internally threaded pipe 82 and the blocking plate, in sequence, the plurality of locking screws 83 are removed, then the snap spring 65 is removed, the blocking disc 64 can be removed from the end face of the inner roller column 4 and the outer roller sleeve 5, and the outer roller sleeve 5 can be removed from the inner roller column 4 for replacement.

[0035] As one of the embodiments of the present application, one end surface of the elliptical strip 74 is fixed with an arc-shaped extrusion strip 9, which is in extrusion contact with the elastic cavity capsule 71; in the design scheme of the present application, when the elliptical strip 74 is rotated to be vertical, at this time, the arc-shaped extrusion strip 9 arranged on the upper end surface of the elliptical strip 74 can increase the extrusion area of the elastic cavity capsule 71, so that the medium in the elastic cavity capsule 71 can fully enter the cavity expansion strip 73, thereby enabling the limiting insertion column 63 to be stably and accurately inserted into the positioning insertion slot 621, so as to further improve the stability and firmness of the vertical insertion strip 61 and the arc-shaped insertion strip 62 in the T-shaped insertion slot 41.
