Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] See also Figure 1-Figure 3 As shown, this embodiment is a cable testing device, comprising:

[0033] The main body assembly includes a support rod 12;

[0034] Auxiliary limiting assembly, the auxiliary limiting assembly includes a fixing rod 21, a set of mounting plates 22, mounting holes 23, and a push rod 24;

[0035] The fixing rod 21 is fixed to the lower side of the support rod 12, and the mounting plates 22 are respectively fixed to both sides of the outer end of the fixing rod 21. The mounting holes 23 are opened on both sides of the mounting plates 22, and the push rod 24 passes through the inner side of the mounting hole 23;

[0036] The fixing rod 21 is used to place other components, and the mounting plate 22 is used to connect and place other components. The mounting plate 22 is fixed to the left and right sides of the outer end of the fixing rod 21. The mounting hole 23 is used for the movement of the push rod 24, and the push rod 24 is used to drive other components to move together;

[0037] The inner end of the push rod 24 is fixedly connected to a clamping frame 25, one side of the clamping frame 25 is fixedly connected to a spring 26, and the other end of the spring 26 is fixedly connected to the inner side of the mounting plate 22;

[0038] The clamping frame 25 can clamp the cable, and the spring 26 is used to connect the clamping frame 25 and the mounting plate 22. At the same time, the spring 26 provides auxiliary support force for the push rod 24, and the spring 26 acts on the push rod 24;

[0039] The inner ends and outer side surfaces of the clamping frame 25 are both magnetic surfaces, and the outer end of the push rod 24 is fixedly connected to the limit ring 27;

[0040] The clamping frames 25 are connected and clamped together by the magnetic surfaces at both ends of the inner side. The clamping frames 25 are adsorbed and connected to the connecting rods 28 by the magnetic surfaces on the outer sides. The connecting rods 28 can limit the clamping frames 25, and the limiting rings 27 can prevent the push rods 24 from completely entering the mounting holes 23.

[0041] A set of connecting rods 28 are fixedly connected to the inner side of the mounting plate 22. The connecting rods 28 are located around the mounting holes 23 and are adsorbed on the outer side of the clamping frame 25.

[0042] The connecting rod 28 is connected to the clamping frame 25 by adsorption through the outer side surface of the clamping frame 25, and the connecting rod 28 limits the clamping frame 25;

[0043] Working principle:

[0044] After the top of the cable is connected to the upper clamp 13, the lower end of the cable is perpendicular to the clamping frame 25. The staff manually pushes the push rod 24, which moves inward of the mounting plate 22 in the mounting hole 23. The clamping frame 25 and the connecting rod 28 are separated. The push rod 24 drives the clamping frame 25 to move relative to each other. At this time, the push rod 24 drives the spring 26 to gradually expand.

[0045] Since both ends of the inner side of the clamping frame 25 are magnetic surfaces, the clamping frame 25 is adsorbed and connected together, so that the clamping frame 25 limits the lower end of the cable, making it easier for the staff to connect the lower end of the cable to the lower clamp 14;

[0046] In the above steps, the lower end of the cable is limited by the interaction between the clamping frames 25 .

[0047] See also Figure 1 、 Figure 4As shown, this embodiment is based on the above embodiment 1 and also includes:

[0048] protective components;

[0049] The protection assembly includes a mounting rod 31 and a vertical cylinder 32;

[0050] The mounting rod 31 is fixed below one side of the support rod 12 and is located above the fixing rod 21 , and the vertical tube 32 is fixed to the outer end of the mounting rod 31 ;

[0051] The mounting rod 31 is used to connect the vertical tube 32, and the vertical tube 32 is used to place the cable;

[0052] The top and bottom ends of the vertical tube 32 are fixedly connected to a short rod 33, and the inner side of the opening of the short rod 33 is fixedly connected to a rubber block 34;

[0053] The short rod 33 and the rubber block 34 are provided to increase the friction between the cable and the rubber block 34, thereby limiting the position of the cable inside the vertical cylinder 32;

[0054] The main assembly also includes a base 11, an upper holder 13, a lower holder 14, and a display 15;

[0055] The support rod 12 is fixed to one side of the top of the base 11, the upper clamp 13 is slidably connected to one side of the support rod 12, the lower clamp 14 is fixed to one side of the top of the base 11 and is located below the upper clamp 13, and the display 15 is fixed to the other side of the top of the base 11;

[0056] The base 11 is used to place other components. The upper clamp 13 and the lower clamp 14 are connected to the top and bottom ends of the cable respectively to facilitate tensile testing. The display 15 is used to display the test results, etc.

[0057] Working principle:

[0058] Insert the cable into the upper short rod 33, then pass through the vertical tube 32 into the lower short rod 33, and finally extend from the lower short rod 33. The rubber block 34 increases the friction of the cable. Then the staff connects the top and bottom ends of the cable to the upper clamp 13 and the lower clamp 14 respectively.

[0059] After connection, the upper clamp 13 is moved upward to gradually unfold the cable. If the cable is torn during the movement of the upper clamp 13, the vertical cylinder 32 can prevent the pieces of material generated at the torn part of the cable from splashing outward.
