Furthermore, it should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, and are not intended to limit the present invention. In the present invention, unless otherwise specified, the use of directional terms such as "upper", "lower", "left" and "right" may refer to directions in which the device is actually used or operated, may refer to directions in the drawings of the drawings, and may refer to two opposite directions; while "inner" and "outer" are with respect to the outline of the device.

Specifically, referring to fig. 1 to 5, the present invention provides a coupling device 200, wherein the coupling device 200 includes a mounting body 210, a sliding component 220 and a fixing element 230. The mounting body 210 includes a receiving cavity 211 and a fixing groove 213, and a through hole 2111 is formed at the bottom of the receiving cavity 211. The sliding assembly 220 includes a cam member 221, a pair of sliding members 222, a pair of first conductive members 223, and a pair of elastic members 224.

Specifically, referring to fig. 2 to 4B, the cam element 221 includes a cam portion 2211 and a mounting portion 2212. Preferably, the cam element 221 is a disc cam; as will be understood by those skilled in the art, a disc cam is a cam having a radial profile that varies in size and rotates about its axis, so that the cam element 221 rotates about the axis XX' of the cam element 221, thereby causing the pair of slide elements 222 to move relative to each other in the width direction of the mounting body 210. The cam portion 2211 includes at least one pair of curved surfaces 2213 symmetrically disposed about the axis XX' of the cam member 221, two first flat surfaces 2215 in the width direction of the cam member 221, and two second flat surfaces 2216 in the longitudinal direction of the cam member 221. The furthest rectilinear distance of the pair of curved surfaces 2213 from the axis XX' is greater than or equal to the length of the cam element 221; the closest linear distance of the pair of curved surfaces 2213 to the axis XX' is greater than or equal to the width of the cam element 221. Specifically, if the farthest linear distance between the pair of curved surfaces 2213 and the axis XX ' is a, the closest linear distance between the pair of curved surfaces 2213 and the axis XX ' is a ', the length of the cam element 221 is B, and the width of the cam element 221 is C, it is required to satisfy: a is more than or equal to B, and A' is more than or equal to C. Preferably, the furthest rectilinear distance of the pair of curved surfaces 2213 from the axis XX' is greater than the length of the cam element 221; the closest linear distance of the pair of curved surfaces 2213 to the axis XX' is greater than the width of the cam element 221, i.e. satisfies: a > B > A' > C; this arrangement ensures that the cam member 221 will not rotate backwards due to vibration or accidental contact, and thus acts as a limit.

Referring to fig. 5, in the present invention, the pair of sliding elements 222 includes a pair of sliding bodies 2221 and a pair of connecting bodies 2222 extending from a side of the pair of sliding bodies 2221 facing away from each other to a top of the pair of sliding bodies 2221; the thickness of the pair of sliding bodies 2221 is the same as the thickness of the cam part 2211, the thickness of the pair of sliding bodies 2221 refers to the farthest vertical distance of the pair of sliding bodies 2221 in the height direction of the coupling device 200, and the thickness of the cam part 2211 refers to the farthest vertical distance of the cam part 2211 in the height direction of the coupling device 200. This arrangement ensures that the cam portion 2211 can drive the pair of sliding bodies 2221 to move relatively in the width direction of the coupling device 200, so that the force is more uniformly applied and the transmission is more stable. Preferably, the thickness of the pair of sliding bodies 2221 and the thickness of the cam portion 2211 are the same as the depth of the receiving cavity 211, and the depth of the receiving cavity 211 refers to the farthest vertical distance of the receiving cavity 211 in the height direction of the coupling device 200.

In the present invention, a pair of first conductive elements 223 are oppositely disposed on the pair of connecting bodies 2222, specifically, protrusions located inside the connecting bodies 2222 are respectively formed on the inner wall and the outer wall of the connecting bodies 2222, and the end portions of the protrusions on the inner wall are bent toward the outer wall, so as to engage the two end portions of the first conductive elements 223 in the connecting bodies 2222, thereby effectively preventing the first conductive elements 223 from falling off. The middle portion of the first conductive element 223 protrudes beyond the inner wall of the connecting body 2222.

Referring to fig. 6, the assembly process of the coupling apparatus 200 is as follows: first, the first conductive element 223 is mounted on the connecting body 2222 of the sliding element 222, then the elastic element 224 is mounted on the mounting groove 2224, and the pair of sliding elements 222 mounted with the first conductive element 223 and the elastic element 224 are mounted in the receiving cavity 211 of the mounting body 210, so that the side wall of the sliding element 222 mounted with the elastic element 224 is close to the inner wall of the mounting body 210; mounting the cam member 221 in the receiving cavity 211 of the mounting body 210 such that the mounting portion 2212 of the cam member 221 is positioned in the through hole 2111 of the receiving cavity 211, the cam portion being in contact with a side wall of the slide body 2221 of the slide member 222; then, the fixing member 230 is placed in the fixing groove 213 and is fixedly coupled to the mounting body 210 by the fastening member 240.

As shown in fig. 7A to 7C, when the first plane 2215 is in contact with the sliding body 2221, the sliding assembly 220 is in an initial position with the relative distance between the pair of sliding elements 222 being closest.

As shown in fig. 8A to 8C, when the switch position 2214 is rotated counterclockwise, i.e. the cam element 221 is rotated, the curved surface 2213 is initially contacted with the sliding main body 2221, and when the switch position 2214 is rotated counterclockwise to 90 °, the second flat surface 2216 is contacted with the sliding main body 2221, and the relative distance between the pair of sliding elements 222 is farthest, where the farthest relative distance does not mean the farthest relative distance of movement, but the farthest relative distance of the pair of sliding elements 222 in the fixed state, and when the sliding main body 2221 has a certain gap with the inner wall of the receiving cavity 211; when the relative distance of the movement is the farthest, the sliding body 2221 is attached to the inner wall of the receiving cavity 211.

The fastener 240 in the present invention is preferably a screw.

In other words, the top surface of the fixing member 230 is at the same level as the inner top surface of the mounting body 210 to ensure the flatness of the inside of the coupling device 200. Preferably, the fixing element 230 is a fixing plate. Wherein the fixing element 230 does not exert a force on the sliding elements 222 in the width direction of the coupling device 200, that is, when the pair of sliding elements 222 relatively moves to a closest distance in the width direction of the coupling device 200, the closest distance is greater than or equal to the width of the fixing element 230, and the width of the fixing element 230 refers to the farthest vertical distance of the fixing element 230 in the width direction of the coupling device 200.
