That is, when the drum 200 rotates to the position where the first limiting hole 211 and the second limiting hole 161 are located, the two ends of the inserted pin are inserted into the first limiting hole 211 and the second limiting hole 161, respectively, and the base 110 is fixed, so that the inserted pin inserted into the second limiting hole 161 at one end is also fixed, and when the other end of the inserted pin is inserted into the first limiting hole 211 on the drum 200, the drum 200 can be limited, so that the drum 200 cannot rotate relative to the base 110.

In some embodiments, the axes of the first limiting hole 211 and the second limiting hole 161 may form an included angle, and at this time, the plug pin needs to be composed of two parts forming an included angle with each other, so that when the first limiting hole 211 and the second limiting hole 161 are located at corresponding positions, two ends of the plug pin can be respectively inserted into the corresponding first limiting hole 211 and the second limiting hole 161, and further the rotation of the drum 200 relative to the base 110 can be prevented.

Specifically, the axis of the first position-limiting hole 211 and the axis of the second position-limiting hole 161 form an included angle, that is, the axes of the first position-limiting hole 211 and the second position-limiting hole 161 cannot coincide, so that the plug pin needs to be composed of two parts, and when one part of the plug pin is inserted into the first position-limiting hole 211, the axis of the other part of the plug pin just coincides with the second position-limiting hole 161, so that the other part of the plug pin can be inserted into the second position-limiting hole 161, and the two ends of the plug pin are respectively inserted into the first position-limiting hole 211 and the second position-limiting hole 161, so as to limit the drum 200.

In some embodiments, as shown in fig. 12, the axes of the first limiting hole 211 and the second limiting hole 161 may also be both parallel to the axis of the drum 200, and on a cross section perpendicular to the axis of the drum 200, the axes of the first limiting hole 211 and the second limiting hole 161 are located on the same circumference, under this structure, the plug pin may adopt a straight rod structure, and when the first limiting hole 211 and the second limiting hole 161 are located at corresponding positions, the plug pin may be sequentially inserted into the first limiting hole 211 and the second limiting hole 161.

It should be noted that, the parts of the straight rod structure provided by the present disclosure need to adopt parts with strong rigidity, and flexible materials, that is, parts capable of bearing large force without bending or breaking, cannot be used.

In addition, the position of the first limiting hole 211 corresponding to the position of the second limiting hole 161 means that two ends of the plug pin can be inserted into the first limiting hole 211 and the second limiting hole 161 at the same time, so that the plug pin can limit the barrel 210 from rotating relative to the base 110. For example, in a scheme that the axes of the first and second limiting holes 211 and 161 are parallel to the axis of the drum 200, the corresponding positions of the first and second limiting holes 211 and 161 refer to positions where the axes of the first and second limiting holes 211 and 161 coincide, and at this time, the plug pins may be sequentially inserted into the first and second limiting holes 211 and 161.

In some embodiments, as shown in fig. 12, a protrusion 160 is disposed on a top surface of a side of the base 110 away from the support frame 120, and the second position-limiting hole 161 is opened on the protrusion 160, so that after the protrusion 160 is disposed, compared with the case where the second position-limiting hole 161 is opened on the base 110 directly, the height of the second position-limiting hole 161 is increased, which can prevent the roller 200 from being disposed too low, and thus other components (e.g., the treatment head) on the roller 200 from contacting the ground; moreover, the thickness of the protrusion 160 does not need to be too thick, so that the processing difficulty of forming the second limiting hole 161 can be reduced.

In some embodiments, as shown in fig. 12, a plurality of first position-limiting holes 211 are formed in an end surface of the cylinder 210 away from the driving disc 220, and the plurality of first position-limiting holes 211 are distributed around the circumference of the cylinder 210. Through setting up a plurality of first spacing holes 211, when needs lock barrel 210, only need make barrel 210 go up apart from the spacing hole 161 of second nearest a first spacing hole 211 rotate to corresponding position can, be favorable to reducing pivoted angle, the operation is more convenient.

As shown in fig. 11, the driving mechanism 300 is in transmission connection with the gear ring 230 disposed on the driving disc 220, that is, the driving mechanism 300 is in transmission connection with only one end of the drum 200, so that the driving mechanism 300 can be disposed at the end of the drum 200 where the driving disc 220 is disposed, thereby preventing the driving mechanism 300 from colliding with other components on the drum 200, and the driving mechanism 300 can be disposed at a position close to the gear ring 230 without being connected through the gear shaft, thereby preventing the transmission efficiency from being reduced.

In addition, the driving mechanism 300 is connected with the friction wheel through a long driving shaft, which affects transmission efficiency, and the friction wheel transmission has a large positioning error, which causes play along the axial direction of the drum 200 during supporting, which affects the rotation precision of the drum 200.
