In the various figures of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration, and thus, are used only to illustrate the basic structure of the subject matter of the present invention.

Terms such as "left", "right", and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "to the right" of other elements or features would then be oriented "to the left" of the other elements or features. Thus, the exemplary term "right side" may encompass both left and right orientations. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Referring to fig. 1, in an embodiment of the present invention, a serpentine spring coupling convenient to maintain includes a serpentine spring coupling body 1 and a shaft sleeve mechanism 2 sleeved on the serpentine spring coupling body 1.

Referring to fig. 1 to 2, a shaft sleeve mechanism 2 is sleeved on the outer side of a serpentine spring coupling body 1 to facilitate fixing of the serpentine spring coupling body 1, the shaft sleeve mechanism 2 includes a first shaft sleeve 201 and a second shaft sleeve 202, the first shaft sleeve 201 is matched with the second shaft sleeve 202, a plurality of mounting holes 203 are drilled on the first shaft sleeve 201, pins 204 matched with the mounting holes 203 are connected to the second shaft sleeve 202, the pins 204 are inserted into the mounting holes 203 to fix the first shaft sleeve 201 and the second shaft sleeve 202, a pair of sliding cavities 205 are drilled on the mounting holes 203, the pair of sliding cavities 205 are all arranged on the same side of the first shaft sleeve 201, the sliding cavities 205 are communicated with the mounting holes 203, and a clamping mechanism is inserted into the sliding cavities 205 to facilitate clamping the pins 204, so that the first shaft sleeve 201 is connected with the second shaft sleeve 202 more firmly.

Referring to fig. 2 to 4, the fastening mechanism includes a sliding rod 206, the sliding rod 206 is slidably disposed in a sliding cavity 205, a locking groove 207 matched with the sliding rod 206 is disposed on the pin 204, so that the sliding rod 206 can be inserted into the locking groove 207 to fix the first sleeve 201 and the second sleeve 202, a limiting member 208 is connected to a side wall of the sliding cavity 205 of the sliding rod 206, a spring 209 is connected between the first sleeve 201 and the limiting member 208, so that the sliding rod 206 has a better fixing effect, and an end cap 210 is connected to an end of the sliding rod 206 far away from the mounting hole 203.

The diameter of the end cap 210 is larger than the diameter of the sliding rod 206, so that the sliding rod 206 is easily limited, the sliding rod 206 is not easy to fall off, and a user can pull the sliding rod 206 conveniently.

Referring to fig. 2 to 4, a first magnet 211 is disposed at one end of the slide rod 206 close to the mounting hole 203, and a second magnet 212 matched with the first magnet 211 is disposed in the pin 204, so that the connection effect is better, and a rubber ring 213 is sleeved on the pin 204 to increase the connection stability between the first sleeve 201 and the second sleeve 202.

The working principle is as follows: when the flexible coupling is used specifically, a user clamps the first shaft sleeve 201 on the flexible coupling body 1, holds the end cap 210 by hand, pulls out the slide rod 206 with force, so that the slide rod 206 is completely retracted into the slide cavity 205, aligns the pin 204 on the second shaft sleeve 202 with the mounting hole 203 on the first shaft sleeve 201, inserts the pin 204 into the mounting hole 203, releases the end cap 210 by hand, slides the slide rod 206 in the slide cavity 205 under the combined action of the spring 209 and the limiting piece 208 until the slide rod 206 is inserted into the clamping groove 207 on the pin 204, so that the first shaft sleeve 201 and the second shaft sleeve 202 are fixed, and meanwhile, the first magnet 211 can adsorb the second magnet 212 in the pin 204, so that the slide rod 206 is not easy to slide in use, thereby increasing the connection effect of the first shaft sleeve 201 and the second shaft sleeve 202 and improving the connection stability; when a user needs to disassemble the serpentine spring coupling body 1, the user only needs to pull the end cap 210 by hand to make 2006 separate from the clamping groove 207, so that the pin 204 can be taken out of the mounting hole 203, the first shaft sleeve 201 and the second shaft sleeve 202 are separated, and the user can maintain the serpentine spring coupling body 1 conveniently.

According to the technical scheme, the invention has the following beneficial effects:
