[0033] Example 1 (Inner rod pressing down to clamp the fabric)

[0034] like Figures 1-7 As shown, the cloth clamping drive structure of the cloth clamping mop includes a mop head and a mop handle. The mop head and the mop handle are rotatably connected. The mop head includes a housing 1, a drive component 3 rotatably installed in the housing 1, a transmission gear 4 rotatably installed in the housing 1 and meshing with the drive component 3, and clamping plates 2 meshing with the transmission gear 4 and retractably disposed on both sides of the housing 1. The mop handle includes a rotating component 8 rotatably connected to the housing 1, an outer rod 5 rotatably connected to the rotating component 8, an inner rod 6 inserted between the rotating component 8 and the outer rod 5 and obliquely slidably connected to the drive component 3, and a limiting component 7 retractably disposed on the inner rod 6 and capable of engaging with the outer rod 5. When the limiting component 7 restricts the inner rod 6 from retracting relative to the outer rod 5, the clamping plates 2 are attached to the side of the housing 1.

[0035] Preferably, the housing 1 and the outer rod 5 are arranged perpendicularly to the rotation axis on the rotating member 8, and when the inner rod 6 extends or retracts relative to the outer rod 5, the direction of extension or retraction of the inner rod 6 is along the center line of the length of the outer rod 5.

[0036] When the limiting member 7 is disengaged from the outer rod 5, the inner rod 6 can be operated to extend or retract relative to the outer rod 5. Through the extension or retraction of the inner rod 6, the inner rod 6 can drive the driving member 3 to rotate forward or reverse. The driving member 3 drives the clamping plate 2 to approach or move away from the two sides of the shell 1 through the meshing transmission gear 4.

[0037] In the present application, the meshing transmission arrangement of the driving member 3 and the clamping plate 2 does not have an upward or downward external force acting on the clamping plate 2. Under the limiting and guiding action of the mop head shell 1, when the driving member 3 extends or retracts relative to the shell 1, no upward or downward force is applied to the shell 1, thereby ensuring the stability of the shell 1 structure and preventing deformation.

[0038] As shown in Figure 2 and Figures 5-6 , the inner rod 6 includes a driving segment 6a that is connected to the driving member 3 and can drive the driving member 3 to rotate, a hinged segment 6b that is rotationally connected to the lower end of the driving segment 6a, a connecting segment 6c that is rotationally connected to the upper end of the hinged segment 6b, and a sleeve 6d that is fixed to the connecting segment 6c.

The action tube 31 is provided with an inclined or arc-shaped guide groove 32, and the driving segment 6a is provided with a matching portion 6a1 that is inserted into the guide groove 32. When the hook portion 72 of the limiting member 7 is disengaged from the hook 51 of the outer rod 5, and the inner rod 6 is operated to extend or retract along the lengthwise center line of the outer rod 5, the matching portion 6a1 on the driving segment 6a of the inner rod 6 slides along the guide groove 32 and can drive the driving member 3 to rotate.

[0043] To ensure the comfort of the inner rod 6 when holding, the outer wall of the inner rod 6 is usually a cylindrical outer wall, to avoid the hooking part from the hook 51 after the inner rod 6 in the outer rod 5 rotating, the shell 1 is provided with a convex column 11, and the inner rod 6 is provided with a lower opening and can be inserted into the insertion hole 6a2 matched with the convex column 11, that is, the insertion hole 6a2 is arranged on the lower end surface of the driving section 6a, the convex column 11 and the insertion hole 6a2 are matched by a non-circular structure, and the non-circular structure includes square or elliptical or triangular structure.

[0047] As shown in Figures 2-4 The shell 1 includes an upper cover 1a and a bottom plate 1b, the upper cover 1a and the bottom plate 1b are fixedly connected by screw connection or buckle connection and the like, the driving part 3, the transmission gear 4 and the two clamping plates 2 are installed between the upper cover 1a and the bottom plate 1b, the upper cover 1a and the bottom plate 1b are spaced apart to form a through groove 13, the rack part 21 and the guide rail part 22 of the clamping plate 2 are inserted into the shell 1 through the through groove 13, and the convex column 11 in the shell 1 protrudes from the upper end surface of the bottom plate 1b.

[0048] The upper cover 1a is provided with a through hole 14, the action pipe part 31 of the driving part 3 is exposed to the through hole 14, and the upper cover 1a is provided with a ring part 15 located outside the action pipe part 31 of the driving part 3, the ring part 15 is located above the gear part 33, when the inner rod 6 is lifted and the driving part 3 is rotated, the ring part 15 offsets the upward force received by the driving part 3, and can be used as a reinforcing rib on the upper cover 1a to improve the structural strength of the upper cover 1a.

[0049] In order to avoid the sliding of the clamping plate 2 out of the shell 1, the upper end surface of the bottom plate 1b is provided with a protruding stop edge, the guide rail part 22 is in a 7-shaped or Z-shaped structure, and the stop edge limits the sliding of the guide rail part 22 out of the shell 1.

[0050] When the two clamping plates 2 are attached to the two sides of the shell 1, the rotation axis between the hinged section 6b and the connecting section 6c is collinear with the rotation axis between the outer rod 5 and the rotating part 8, and the rotation axis between the hinged section 6b and the driving section 6a is collinear with the rotation axis between the rotating part 8 and the shell 1, that is, the rotating part 8 rotates relative to the shell 1 while the hinged section 6b rotates relative to the driving section 6a, and the outer rod 5 rotates relative to the rotating part 8 while the connecting section 6c rotates relative to the hinged section 6b.

[0051] In order to avoid the interference of the action pipe part 31 on the driving part 3 with the rotation of the hinged section 6b, the action pipe part 31 is provided with a through avoiding opening 34, so that the hinged section 6b can rotate into the avoiding opening 34.
