[0022] It needs to be explained that, since the fixing operation of the anti-disengagement limiting structure of the existing electronic connector is relatively cumbersome, the length is fixed and cannot be adjusted, therefore, in order to solve the problems in the use of the anti-disengagement limiting structure of the existing electronic connector, the present scheme solves the problems of the fixing operation of the anti-disengagement limiting structure of the existing electronic connector being relatively cumbersome and the length being fixed and cannot be adjusted by additionally arranging the fixed assembly 2 and the cooperation of the components inside and on the top of the outer cylinder 1 in the inner cavities of the two fixed bases 3.

[0023] As shown in the further preferred embodiment of the present application, Figures 1-3 two connecting shafts 22 are connected to the front side of each of the two fixed plates 21 near the center, and a support base 24 is connected to the front end of each of the two connecting shafts 22, a driving plate 28 is arranged on the front side of each of the two fixed plates 21, a connecting rod 25 is connected to the rear side of each of the two driving plates 28 near the center, and a pressing base 29 is connected to the rear end of each of the two connecting rods 25, a threaded rod 27 is connected to the front side of each of the two driving plates 28 near the center, and an opening is arranged on the front side of each of the two fixed assemblies 2 near the center, and the front end of each of the two threaded rods 27 near the front end is movably connected to the adjacent opening.

[0024] In the present embodiment, when the anti-disengagement limiting structure is to be fixed at the line connection of the electronic connector for use, the worker first passes the line on one side through the inside of the two fixed bases 3 and the inner cylinder 7 and connects it with the line on the electronic connector, then adjusts the length of the anti-disengagement limiting structure, and when the length of the anti-disengagement limiting structure is adjusted to the length that can completely cover the line connection, the worker moves the anti-disengagement limiting structure so that the line connection is completely located inside the inner cylinder 7, and then the worker moves the two threaded rods 27 towards the inside of the two fixed bases 3, and when the two threaded rods 27 move towards the inside of the two fixed bases 3, they can drive the two driving plates 28 to move towards the center of the inner cavities of the two fixed bases 3, and thus the two driving plates 28 can drive the two pressing bases 29 to move towards the center of the inner cavities of the two fixed bases 3 through the adjacent connecting rods 25, so that the line can be quickly fixed between the adjacent support bases 24 and the pressing bases 29, thereby achieving the purpose of conveniently fixing the anti-disengagement limiting structure, and the worker can quickly fix it at the line connection for use, thereby improving the installation efficiency to a certain extent.

[0025] As shown in the further preferred embodiment of the present application, Figures 1-3 a handle 210 is sleeved on each of the two threaded rods 27 near the front end, and the rear side of each of the two handles 210 is movably connected to the front side of the adjacent fixed base 3 near the center, a driving hole is arranged in the inner cavity of each of the two handles 210 near the center, and an inner thread matched with the threaded rod 27 is arranged on the inner wall of each of the two driving holes.

[0026] In this embodiment, the operator rotates the two handles 210 in the forward direction in sequence. Since the two handles 210 are threadedly engaged with the adjacent threaded rods 27 through the drive holes, the two handles 210 can quickly drive the two threaded rods 27 to move into the two fixed seats 3.

[0027] In a further preferred embodiment of this utility model, such as Figure 3 As shown, limit holes are provided in the inner cavities of the two drive plates 28 near the center of the upper and lower sides. T-shaped limit rods 26 are movably connected to the inner cavities of the two limit holes on the left and right sides. The two T-shaped limit rods 26 on the left and right sides are symmetrically arranged with the center of the inner cavity of the adjacent drive plates 28 as the axis of symmetry. The narrower end of the T-shaped structure of the two T-shaped limit rods 26 on the left and right sides penetrates the inner cavity of the adjacent limit hole and is connected to the inner wall of the front side of the adjacent fixed seat 3 near the center.

[0028] In this embodiment, when the two drive plates 28 move toward the center of the inner cavity of the two fixed seats 3, they can slide on the two adjacent T-shaped limiting rods 26, thereby limiting the position of the two drive plates 28 and allowing the two drive plates 28 to move smoothly.

[0029] In a further preferred embodiment of this utility model, such as Figures 1-3 As shown, both threaded rods 27 have a baffle 211 at their front ends, and the rear side of both baffles 211 is connected to the front end of the adjacent threaded rod 27 near the center.

[0030] In this embodiment, by connecting baffles 211 to the front ends of both threaded rods 27, the positions of the two threaded rods 27 can be limited, thus preventing the two threaded rods 27 from moving and overloading.

[0031] In a further preferred embodiment of this utility model, such as Figure 1 , 2 As shown in Figure 4, a return spring 9 is sleeved on the lever 8 near its top end. The top end of the return spring 9 is connected to the bottom of the handle 4 near the center, and the bottom end of the return spring 9 is connected to the bottom inner wall of the fixed cylinder 5 near the center.

[0032] In this embodiment, when the operator needs to adjust the length of the anti-detachment limiting structure, the operator pulls the handle 4 upwards. As the handle 4 moves upwards, it moves the locking rod 8 upwards, allowing it to be pulled out from the adjacent locking hole. This releases the restriction on the inner cylinder 7, allowing the operator to pull the inner cylinder 7 out from the outer cylinder 1 and extend the length of the anti-detachment limiting structure. This achieves the purpose of adjusting the length of the anti-detachment limiting structure, enabling it to better cover the wiring connection for practical use. After adjusting the anti-detachment limiting structure to the required length, the operator stops pulling the handle 4. The external force on the return spring 9 disappears, and it begins to contract inwards, causing the handle 4 to move downwards. This allows the handle 4 to push the locking rod 8 back into the adjacent locking hole, thus limiting the position of the inner cylinder 7 and fixing the length of the anti-detachment limiting structure, allowing it to better cover the wiring connection for use.

[0033] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a slide is provided near the center of the inner cavity of the outer cylinder 1. A limiting plate 6 is movably connected to the inner cavity of the slide, and the top of the limiting plate 6 passes through the inner cavity of the slide and is connected to the bottom of the inner cylinder 7 near the center of the right side.

[0034] In this embodiment, when the inner cylinder 7 moves from inside the outer cylinder 1, it can drive the limiting plate 6 to slide inside the slide, thereby limiting the position of the inner cylinder 7 and allowing the inner cylinder 7 to move smoothly.
