[0039] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] The following will be combined with the attached Figure 1-5 , the present invention is further described.

[0041] In the embodiment of the present invention, Figure 1-Figure 3 As shown, the connection auxiliary structure of the insulating operating rod includes: a first connecting sleeve 1, a second connecting sleeve 2, a folding assembly 3 and a locking assembly; the first connecting sleeve 1 and the second connecting sleeve 2 are independently arranged; the folding assembly 3 includes a first folding link 301 and a second folding link 302, one end of the first folding link 301 is movably arranged in the first connecting sleeve 1, and the other end thereof is hinged in the second connecting sleeve 2, one end of the second folding link 302 is movably arranged in the second connecting sleeve 2, and the other end thereof is hinged in the first connecting sleeve 1, the first folding link 301 and the second folding link 302 are rotatably connected, so that under the action of external force, The first and second folding links 301, 302 rotate simultaneously and link the first and second connecting sleeves 1, 2 to form a folded state or an upright state. In the folded state, the first and second folding links 301, 302 are partially protruded from the outside of the first and second connecting sleeves 1, 2. In the upright state, the first and second folding links 301, 302 are hidden in the first and second connecting sleeves 1, 2. The locking assembly includes a locking member 4 and a matching member 5, which are respectively arranged on the first connecting sleeve 1 and the second connecting sleeve 2, and can lock the first and second connecting sleeves 1, 2 in the upright state to limit the relative movement of the first and second connecting sleeves 1, 2.

[0042] Specifically, in an embodiment of the present invention, the first connecting sleeve 1 and the second connecting sleeve 2 are arranged independently of each other, and a first folding link 301 and a second folding link 302 are arranged at the same end surface of the two. The two connecting sleeves can be linked to form a folded state or an upright state. In the folded state, the axes of the two connecting sleeves are arranged in parallel to shorten the length of the overall structure for easy storage and carrying; conversely, in the upright state, the axes of the two connecting sleeves are arranged in a collinear manner to extend the length of the overall structure for easy achievement of an ideal length.

[0043] Specifically, both folding links have two end portions; wherein, one end of the first folding link 301 is movably disposed in the first connecting sleeve 1, and the other end thereof is hinged in the second connecting sleeve 2; one end of the second folding link 302 is movably disposed in the second connecting sleeve 2, and the other end thereof is hinged in the first connecting sleeve 1, and the first folding link 301 and the second folding link 302 are rotatably connected; in this way, under the action of external force, the ends of the two folding links can be rotated around their corresponding hinge points, and the corresponding folding links can be pushed to gradually extend into or out of the corresponding connecting sleeves, so as to be hidden or protruded from the connecting sleeves, thereby linking the two connecting sleeves to form a folded state or an upright state. That is: in the folded state, the two folding connecting rods are partially located outside the two connecting sleeves; conversely, in the upright state, the two folding connecting rods are hidden inside the two connecting sleeves; on the one hand, the two connecting sleeves can be quickly switched between the two states, and the operation is quick and simple, and does not require the cooperation of multiple people; on the other hand, the installation of the two folding connecting rods does not require other installation space, and the internal space of the two connecting sleeves can be reasonably utilized to make the structure more compact; and the two connecting sleeves can be connected by extending the corresponding folding connecting rod, thereby improving the strength of the connection between the two connecting sleeves, and preventing the two connecting sleeves from separating without the action of external force. Of course, if Figure 3 As shown, in order to adapt to the installation positions of various components, the two folding connecting rods in this embodiment are approximately in the shape of a "door".

[0044] In the embodiment of the present invention, the locking assembly is defined to include a locking member 4 and a matching member 5, which are respectively arranged on the first connecting sleeve 1 and the second connecting sleeve 2, and the locking assembly has a locking state and an unlocking state. In the locked state, the locking member 4 and the matching member 5 are connected to keep the two connecting sleeves in an upright state; on the contrary, in the unlocking state, the locking member 4 and the matching member 5 are separated to release the two connecting sleeves so that they can form a folded state. By setting the locking assembly, the stability of the two connecting sleeves in the upright state can be improved to prevent loosening.

[0045] In this embodiment, the first folding link 301 and the second folding link 302 are matched to change the connection mode of the two connecting sleeves, so that the two connecting sleeves can be folded and connected upright; it is easy to carry and store, and can be quickly switched between the folded state and the upright state by a simple external force, without complicated operations; at the same time, the design of the folding link fully utilizes the internal space of the connecting sleeve, making the overall structure more compact. In addition, in the upright state, the locking assembly can effectively fix the position of the connecting sleeve, increasing the stability during use; in the absence of external force, the locking assembly can prevent the connecting sleeve from accidentally separating, improving the safety of use.

[0046] In one embodiment, if Figure 3 As shown, a first slide groove 101 is provided in the first connecting sleeve 1 along its axial direction, and a first slider 102 is slidably provided in the first slide groove 101 for rotationally connecting to the first folding link 301; a second slide groove 201 is provided in the second connecting sleeve 2 along its axial direction, and a second slider 202 is slidably provided in the second slide groove 201 for rotationally connecting to the second folding link 302. Specifically, since the first connecting sleeve 1 and the second connecting sleeve 2 need to switch between the folded state and the upright state, in this process, in order to make the two folding links extend into or out of the corresponding connecting sleeves; in this embodiment, the first slide groove 101 and the second slide groove 201 are respectively provided in the two connecting sleeves along their respective axial directions, and a slider is slidably provided in each slide groove, namely: the first slider 102 and the second slider 202, so that the end of the first folding link 301 connected to the first connecting sleeve 1 is actually rotationally connected to the first slider 102, and the end of the second folding link 302 connected to the second connecting sleeve 2 is actually rotationally connected to the second slider 202; in this way, when the folded state is switched to the upright state, , an external force acts on any one of the connecting sleeves, driving the connecting sleeve to flip toward the other connecting sleeve, so that the first slider 102 and the second slider 202 slide along the first slide groove 101 and the second slide groove 201 respectively, and pull the corresponding first folding link 301 and the second folding link 302 to gradually extend into the two connecting sleeves; at the same time, the first hinge point formed by the first folding link 301 and the second connecting sleeve 2, the second hinge point formed by the second folding link 302 and the first connecting sleeve 1, and the third hinge point formed by the first folding link 301 and the second folding link 302 all rotate until the two folding links are completely located in the two connecting sleeves, realizing the upright docking of the two connecting sleeves. Conversely, when the upright state is switched to the folded state, the above movement direction is reversed, which will not be described in detail here.

[0047] In this way, the first slide groove 101 and the second slide groove 201 are respectively provided with the first slider 102 and the second slider 202, which enables the first folding link 301 and the second folding link 302 to move more smoothly during the movement, reduces friction and jamming, and ensures that the movement of the connecting sleeve is smoother when folding and unfolding. At the same time, the design of the slider and the slide groove provides a precise guiding effect for the folding link, so that the folding link can accurately move along the predetermined track during the sliding process, and improves the accuracy of the folding and unfolding action; and the sliding contact between the slider and the slide groove can reduce the direct wear between the parts, prolong the service life of the folding link and the connecting sleeve, help maintain the stability of the folding link during the movement, and prevent shaking or instability in the folded or upright state. Of course, the slide groove is hidden in the connecting sleeve, so that the folding link can be completely hidden inside the connecting sleeve in the upright state, further optimizing the compactness of the structure, making the overall structure more compact and simple, and reducing the safety hazards caused by loose parts.

[0048] Further, in one embodiment, if Figure 3 As shown, in the folded state, the first slider 102 and the second slider 202 are located at the head end of the first slide 101 and the head end of the second slide 201, respectively. That is, in the upright state, the folding link has been extended to the maximum extent outside the connecting sleeve, so that the overall structure is more compact in the folded state, which is convenient for storage and carrying; and a clear positioning point can be provided, so that the folding link is not easy to slide out of the slide in the folded state, which increases the stability and reliability of the structure, reduces the interference between the slider and other parts of the slide, and avoids the problem of jamming or inconvenience in operation caused by improper position of the slider. Similarly, in the upright state, the first slider 102 and the second slider 202 are located at the end of the first slide 101 and the end of the second slide 201, respectively; used to bring the two folding links into the two connecting sleeves under the action of the two sliders, the hidden design can reduce the interference of the folding link on the connection of the connecting sleeve, and can also improve the structural strength of the connection.

[0049] Further, in one embodiment, if Figure 3As shown, the hinge point between the first folding link 301 and the second connecting sleeve 2 is arranged near the head end of the second slide slot 201. In the folded state, the connection point between the first folding link 301 and the second connecting sleeve 2 is closer to the innermost position of the second slide slot 201, reducing the interference of the folding link with other components during the folding process, making the folding action smoother; the space inside the connecting sleeve can also be used to the maximum extent, and in the upright state, the first folding link 301 can enter the second connecting sleeve 2 more deeply, making the overall structure more compact; at the same time, the hinge point is close to the head end of the second slide slot 201, which helps the first folding link 301 to be more stably hidden in the second connecting sleeve 2 in the upright state, reducing the shaking or instability caused by the unreasonable position of the hinge point, making it easier to control the movement path of the folding link, simplifying the operation process, and making the folding and unfolding actions smoother. Of course, the travel length of the slider in the slide slot can also be reduced, thereby reducing the possible offset or jamming of the slider during the sliding process, improving the reliability of the mechanism, and the sliding distance is short, thereby reducing the friction between the slider and the slide slot, which helps to extend the service life of the slider and the slide slot. Similarly, the hinge point between the second folding link 302 and the first connecting sleeve 1 is arranged close to the head end of the first slide slot 101.

[0050] Furthermore, in one embodiment, in the upright state, the head end of the first slide groove 101 is arranged close to the head end of the second slide groove 201. Specifically, in order to realize the switching of the two connecting sleeves from the folded state to the upright state, this embodiment defines that the head ends of the two slide grooves are close to each other in the upright state, and the ends thereof are far away from each other; in this way, one connecting sleeve can be flipped relative to the other connecting sleeve for upright docking, and the rotation angle between the two connecting sleeves can be reduced, thereby facilitating quick installation and disassembly without the participation of too many people. In this embodiment, Figure 3 As shown, the head end of the first slide groove 101 and the head end of the second slide groove 201 are respectively close to the upper end of the first connecting sleeve 1 and the upper end of the second connecting sleeve 2; similarly, the ends of the two are respectively located at the lower end of the first connecting sleeve 1 and the lower end of the second connecting sleeve 2.

[0051] In one embodiment, if Figure 1-Figure 3As shown, the locking member 4 includes a plurality of opening and closing parts 401, which are arranged around the first connecting sleeve 1 and can expand outward or contract inward relative to the first connecting sleeve 1; the matching member 5 includes a limiting ring 501 arranged on the second connecting sleeve 2, which, in an upright state, wraps around the plurality of opening and closing parts 401 to limit the opening and closing parts 401 from moving outward. Specifically, in order to achieve the locking state of the two connecting sleeves in an upright state; this embodiment defines the locking member 4 as a plurality of opening and closing parts 401, and the matching part as the limiting ring 501; in this way, the limiting ring 501 can be used to limit the opening and closing parts 401 to lock the two connecting sleeves.

[0052] Specifically, a plurality of opening and closing parts 401 are arranged on the outer surface of the first connecting sleeve 1 in a circular array with the axis of the first connecting sleeve 1, and the plurality of opening and closing parts 401 can expand outward or contract inward relative to the first connecting sleeve 1 therein; when the plurality of opening and closing parts 401 expand outward synchronously, they will gradually abut against the inner surface of the limiting ring 501 to form a stable limiting locking structure, thereby locking the two connecting sleeves; conversely, when the plurality of opening and closing parts 401 contract inward synchronously, they gradually move away from the limiting ring 501, and the two connecting sleeves can be unlocked after the two are separated. On the other hand, the plurality of opening and closing parts 401 are arranged around the first connecting sleeve 1, and can also play a role in restraining the first connecting sleeve 1 in an upright state, and can provide a uniform locking force to ensure that there is no relative movement between the two connecting sleeves in an upright state. Furthermore, the opening and closing portion 401 can expand outward or contract inward relative to the first connecting sleeve 1, so that the operator can achieve locking or unlocking through simple manual operation, and the locking and unlocking actions can be quickly completed without tools, thereby improving work efficiency. Of course, the arrangement of multiple opening and closing portions 401 allows the locking member 4 to adapt to certain size changes. Even if there is a slight tolerance between the connecting sleeves, reliable locking can be achieved through the elastic deformation of the opening and closing portion 401, and it can withstand repeated expansion and contraction, thereby extending the service life of the locking assembly. In addition, the design of the opening and closing portion 401 and the limiting ring 501 makes full use of the existing space, so that the entire locking assembly has a compact structure and does not occupy too much extra space, so that the operating rod remains compact in the folded state, which is convenient for carrying and storage. In the upright state, the limiting ring 501 can firmly wrap the opening and closing portion 401 to prevent accidental unlocking during use, thereby ensuring the stability of the entire device during use and reducing the potential safety hazards caused by locking failure.

[0053] In one embodiment, if Figure 1-Figure 4As shown, the locking member 4 also includes: a driving part 402, a mounting part 403 and a guiding part; the driving part 402 is movably arranged on the first connecting sleeve 1; the mounting part 403 is fixed to the first connecting sleeve 1 and is spaced apart from the driving part 402, and a plurality of the opening and closing parts 401 are slidably arranged on the mounting part 403; the guiding part includes a plurality of guiding links 405 and a plurality of guiding columns 406 which are arranged in a one-to-one correspondence, one end of the guiding link 405 is rotatably arranged on the driving part 402, and the other end thereof is rotatably connected to one end of the guiding column 406, and the other end of the guiding column 406 passes through the mounting part 403 and is connected to the corresponding opening and closing part 401, and under the action of external force, the driving part 402 moves in a direction close to or away from the mounting part 403, so as to link the opening and closing part 401 to move outward or inward through the guiding link 405 and the guiding column 406.

[0054] Specifically, in order to drive the multiple opening and closing parts 401 to expand outward or contract inward synchronously, the present embodiment sequentially sleeves the driving part 402 and the mounting part 403 on the outer surface of the first connecting sleeve 1, and the driving part 402 is connected to the opening and closing parts 401 through the guide part, which is used to guide the opening and closing parts 401. Figure 3 , Figure 4 As shown, the driving part 402 is a circular ring structure surrounding the first connecting sleeve 1, which can move back and forth along the axial direction of the first connecting sleeve 1 under the action of external force, causing the guide connecting rod 405 of the guide part to rotate, and linking the corresponding opening and closing part 401 to move along the radial direction of the first connecting sleeve 1 through the guide column 406. When the external force acts on the driving part 402, the driving part 402 will move in the direction close to or away from the mounting part 403.

[0055] That is, the movement of the driving part 402 is transmitted to the guide column 406 through the guide link 405, and the guide column 406 drives the opening and closing part 401 to expand outward or contract inward through its connection with the opening and closing part 401. In the upright state, multiple opening and closing parts 401 expand outward, and the limit ring 501 wraps the opening and closing part 401 to limit its outward movement, thereby achieving the locking of the two connecting sleeves; when unlocking is required, an external force is applied in the reverse direction to make the opening and closing part 401 contract inward, release the constraint of the limit ring 501, and thus unlock the two connecting sleeves. The locking assembly ensures the uniform expansion and contraction of the opening and closing part 401 through the linkage mechanism of the driving part 402, the guide link 405 and the guide column 406, thereby providing a reliable locking effect and strong reliability; the user only needs to apply external force to the driving part 402 to achieve locking or unlocking, which is simple and quick to operate, does not require additional tools, and is easy to operate. In addition, the arrangement of multiple opening and closing parts 401 can adapt to the small-range size changes between the connecting sleeves, ensuring that effective locking can be achieved in different situations. All components are integrated in a compact space without taking up additional space, so that the operating rod remains compact in the folded state. In the upright state, the limit ring 501 can firmly wrap the opening and closing part 401 to prevent accidental unlocking, ensuring the stability of the entire device during use. Of course, in other embodiments, the positions of the locking member 4 and the matching member 5 can be interchanged, that is, the locking member 4 is arranged at the second connecting sleeve 2, and the matching member 5 is arranged at the first connecting sleeve 1, which will not be described in detail here.

[0056] Furthermore, in one embodiment, if Figure 4As shown, the mounting portion 403 is provided with a plurality of guide grooves 404 , and the plurality of guide grooves 404 are arranged in one-to-one correspondence with the plurality of guide posts 406 , and extend along the corresponding moving direction of the opening and closing portion 401 . Specifically, in order to define the moving path of the opening and closing portion 401 so that it can reciprocately expand outward or contract inward along the radial direction of the first connecting sleeve 1; this embodiment provides a plurality of guide grooves 404 on the mounting portion 403, the number of the plurality of guide grooves 404 is consistent with the number of the plurality of guide posts 406, and the guide grooves 404 extend along the radial direction of the first connecting sleeve 1; in this way, the guide posts 406 penetrate the mounting portion 403 using the guide grooves 404, and connect the opening and closing portion 401 and the guide connecting rod 405, so that when the guide connecting rod rotates, it can pull or push the guide posts 406 to slide in the guide grooves 404, and then the opening and closing portion 401 can be expanded outward or contracted inward, ensuring that the guide posts 406 slide smoothly along the preset direction when moving, reducing the risk of deviation from the track, reducing friction, avoiding unnecessary shaking or jamming, making the movement of the guide posts 406 smoother, and reducing energy loss. At the same time, the guide groove 404 also ensures the symmetry and consistency of the opening and closing part 401 when expanding and contracting, making the locking and unlocking actions more reliable. In the upright state, the guide groove 404 helps maintain the correct position of the opening and closing part 401 to prevent it from deviating due to external forces, ensuring the reliability of the locking, and the user can achieve locking or unlocking with simple actions without complicated operation steps.

[0057] like Figure 1 As shown, in one embodiment, the first connecting sleeve 1 is threadedly sleeved with a first locking nut 407 for supporting and pushing the driving part 402. Specifically, in order to push the driving part 402 to move back and forth along the axial direction of the first connecting sleeve 1, in this embodiment, the first locking nut 407 is sleeved on the external thread of the first connecting sleeve 1, and the first locking nut 407 can be rotated by external force to change its position height at the first connecting sleeve 1, so that the driving part 402 can be pushed to move in the direction of the mounting part 403 or away from the mounting part 403, and then the purpose of expansion or contraction of the opening and closing part 401 can be achieved. At the same time, the first locking nut 407 can be suspended at any height of the first connecting sleeve 1, which is convenient and quick to operate, and can prevent the opening and closing part 401 from detaching from the limit ring 501 without the action of external force.

[0058] On the other hand, the second connecting sleeve 2 is threadedly sleeved with a second locking nut 502, which is used to support and push the limiting ring 501. Specifically, in order to reduce or eliminate the obstruction of the limiting ring 501 to the docking or folding of the two connecting sleeves; in this embodiment, the second locking nut 502 is arranged on the outer surface of the second connecting sleeve 2, and the feeding of the second locking nut 502 can push the limiting ring 501 close to or away from the clutch 401, so that the limiting ring 501 has an avoidance function, and the locking assembly can be operated after the two connecting sleeves are completed. Of course, in the folded state, in order to prevent the limit ring 501 from sliding freely at the second connecting sleeve 2, the limit ring 501 and the second locking nut 502 which are independently arranged are fixed in this embodiment so that the two form a whole; that is, when the external force acts on the second locking nut 502, the second locking nut 502 and the limit ring 501 rotate synchronously, and the first locking nut 407 is operated to control the opening and closing size of the opening and closing part 401 after rotating to a suitable position; at the same time, a plurality of reinforcing ribs are arranged between the limit ring 501 and the second connecting sleeve 2, which play a role in structural reinforcement. In actual operation, the length of the thread structure on the two connecting sleeves can be controlled, that is, the specific moving distance of the two locking nuts can be controlled; or a scale line can be set on the surface, and the scale line can be used to visually check the moving distance of the corresponding locking nut. Of course, in other embodiments, in order to protect the locking assembly, two shells are provided, one of which is used for the guide part of the locking member 4, and the other shell is used to wrap the limit ring 501, which can not only prevent the damage of the corresponding parts, but also make the overall structure more beautiful and complete.
