[0008] Furthermore, the limit block forms a telescopic structure between the spring and the groove, and the surface of the docking sleeve is provided with a limit groove and a sliding hole. Through the arrangement of the limit block and the spring, the support frame can be limited when it is rotated to a specified angle.

[0009] Furthermore, a storage groove is provided inside the support frame, and a threaded rod is rotatably connected to the inner wall of the storage groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model rotates the support frame so that the limit block is inserted into the limit groove. At this time, the support frame is in a limit state and is connected to the position of the wire through the first docking groove. Since the position of the wiring head has a larger and thicker protective cover, the diameter of the first docking groove is smaller than the protective cover of the wiring head, so that the wiring head cannot fall off from the wiring port;

[0015] 2. The utility model rotates the rotating cap, which drives the threaded rod to rotate. Since the threaded rod and the threaded sleeve are threadedly driven, the movable seat can move. When the movable seat contacts and squeezes the protective cover of the terminal head, the rotating cap stops rotating, so that the terminal heads are more closely connected, thereby avoiding poor contact.

[0024] like Figure 1-Figure 6As shown, an assembled anti-fall impedance tester comprises: a panel 1, a side panel 2, a display screen 3, a wiring port 4 and a support leg 5, wherein a connection seat 6 is connected to the edge of the display screen 3, a support rod 7 is arranged between the two connection seats 6, a docking sleeve 8 is sleeved on the outer side of the support rod 7, a support frame 9 is installed on the outer side of the docking sleeve 8, a first docking groove 15 is provided at one end of the support frame 9 away from the docking sleeve 8, a groove 18 is provided on the surface of the support rod 7, a limit block 19 is slidably connected inside the groove 18, a spring 20 is connected to one end of the limit block 19, and the end of the spring 20 away from the limit block 19 is docked with the groove 18; side panel 2 is made of iron sheet, and the cross-sectional shape of the support frame 9 is "L"-shaped. Through the setting of the support frame 9, the wires can be regulated; the limit block 19 forms a telescopic structure through the spring 20 and the groove 18, and the surface of the docking sleeve 8 is provided with a limit groove 21 and a slide hole 22. Through the setting of the limit block 19 and the spring 20, the support frame 9 can be limited when it is rotated to a specified angle; the limit groove 21 and the slide hole 22 are interconnected, and the inside of the slide hole 22 is slidably connected with a slide rod 23. Through the setting of the slide rod 23, through the setting of the limit groove 21 and the slide hole 22, the support frame 9 can be reset after limiting.

[0025] like Figure 1-Figure 3 As shown, when the assembled anti-fall impedance tester is used, a receiving groove 10 is provided inside the support frame 9, and a threaded rod 11 is rotatably connected to the inner wall of the receiving groove 10, and a threaded sleeve 12 is threadedly transmitted on the outer side of the threaded rod 11. Through the arrangement of the threaded rod 11 and the threaded sleeve 12, the movable seat 13 can be moved; a movable seat 13 is provided on the outer side of the threaded sleeve 12, and a rotating cap 14 is connected to one end of the threaded rod 11 extending out of the receiving groove 10, and the arrangement of the rotating cap 14 facilitates the operation of the threaded rod 11; a second docking groove 16 is provided on the surface of the movable seat 13, and a magnetic suction plate 17 is provided on the back of the support frame 9. Through the arrangement of the magnetic suction plate 17, the support frame 9 is not easy to rotate at will after being stored.

[0026] Working principle: When using the assembled anti-falling impedance tester, first, when the device is connected, the support frame 9 at the corresponding position is rotated so that the limit block 19 is inserted into the limit groove 21. At this time, the support frame 9 is in a limited state and is not easy to be rotated at will. It is docked with the wire position through the first docking groove 15. Since the position of the terminal head will have a larger and thicker protective cover, the diameter of the first docking groove 15 is smaller than the protective cover of the terminal head, so that the terminal head cannot fall off from the wiring port 4. At the same time, by rotating the rotating cap 14, the rotating cap 14 drives the threaded rod 11 to rotate. Since the threaded rod 11 and the threaded sleeve 12 are threaded transmission, the movable seat 13 can move. When the movable seat 13 contacts and squeezes the protective cover of the terminal head, stop rotating the rotating cap 14, so that the terminal head is docked more tightly, thereby avoiding poor contact. This is the working principle of the assembled anti-falling impedance tester.
