[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] During operation, since the existing electric measuring module is fixed, when the lengths of some branches of the electric measuring module are inconsistent or similar, the module needs to be pulled back and forth for detection, which makes the module easy to be damaged and affects the detection efficiency. In this solution, in the initial state, the spring 10 will always push the baffle 8 downward, so that the baffle 8 drives the slider 9 to remain at the lowest point of the slide slot 7, thereby keeping the bellows 5 in an extended state, and making the clamping block 13 stuck in the storage slot 2. When in use, the electric measuring module 15 is pulled, and the electric measuring module 15 drives the clamping block 13 to move, and the signal line 12 is connected to the electric measuring module 15 and the second fixing clip 14 is stuck on the signal line 12, so that when pulled, the signal line 12 drives the clamping block 13 to move. The baffle 8 moves upward, and when the baffle 8 moves upward, it will drive the slider 9 to slide upward in the slide groove 7. At the same time, when the baffle 8 moves upward, it will squeeze the spring 10 upward to make it contract. After the spring 10 contracts, it will contract the bellows 5 under the pressure of the baffle 8, and then the signal line 12 can be pulled out of the bellows 5. After the detection is completed, the signal line 12 will be retracted into the bellows 5 under the action of the spring 10, and the block 13 will be re-stored into the storage groove 2. The purpose of extension is achieved by cooperation, and the function of detecting electrical measurement modules with branches of different lengths is realized, which effectively improves the convenience of operation of the electrical measurement module detection and effectively improves the detection efficiency of the electrical measurement module.

[0026] See also Figure 4-8As shown, an external threaded tube 16 is installed in the hole of the fixed disk 3, an internal threaded tube 18 is arranged outside the external threaded tube 16, a connecting tube 19 is installed under the internal threaded tube 18, a No. 1 limiting ring 20 is installed at the bottom of the connecting tube 19, a fixing ring 4 is installed at the top inside the fixing ring 4, the connecting tube 19 is located in the No. 2 limiting ring 21, and the No. 2 limiting ring 21 is located directly above the No. 1 limiting ring 20, a hexagonal disk 17 is installed on the outside of the internal threaded tube 18, and the hexagonal disk 17 is located above the fixing ring 4, the No. 2 limiting ring 21 is located below the fixing ring 4, and the No. 2 limiting ring 21 and the fixing ring 4 are rotatably arranged on the outside of the connecting tube 19.

[0027] During operation, in order to ensure the normal use of the electrical measurement module in this scheme and avoid excessive twisting of the signal line during installation and use, which may cause line damage and affect the detection effect, in this scheme, the internal threaded tube 18 is aligned with the external threaded tube 16 during installation, and then the hexagonal disk 17 is rotated. When the hexagonal disk 17 rotates, it will drive the internal threaded tube 18 to rotate, and when the internal threaded tube 18 rotates, it will drive the No. 1 limit ring 20 to rotate under the No. 2 limit ring 21 through the connecting tube 19. At this time, since the bellows 5 and the sleeve 6 are installed under the fixing ring 4, and the fixing ring 4 is rotatably arranged outside the connecting tube 19 through the No. 2 limit ring 21, when the internal threaded tube 18 rotates, it will not drive the bellows 5 and the sleeve 6 to rotate, thereby avoiding twisting of the signal line 12, and when the internal threaded tube 18 rotates, it will be arranged on the outside of the external threaded tube 16 through the threaded sleeve, which achieves the effect of facilitating installation and effectively ensures the normal detection and use of the electrical measurement module in this scheme.

[0028] Working principle: in the initial state, the spring 10 will always push the baffle 8 downward, so that the baffle 8 drives the slider 9 to remain at the lowest point of the slide groove 7, thereby keeping the bellows 5 in an extended state, and the clamping block 13 is clamped in the storage groove 2. When in use, the electric measuring module 15 is pulled, and the electric measuring module 15 drives the clamping block 13 to move, and the signal line 12 is connected to the electric measuring module 15 and the second fixing clip 14 is clamped on the signal line 12, so that when pulled, the baffle 8 is driven to move upward through the signal line 12, and when the baffle 8 moves upward, it drives the slider 9 to slide upward in the slide groove 7. At the same time, when the baffle 8 moves upward, it will squeeze the spring 10 upward to shrink it. After the spring 10 shrinks, the bellows 5 will shrink under the squeezing of the baffle 8, and then the signal line 12 can be pulled out of the bellows 5. After the detection is completed, the signal line 12 will be retracted into the bellows 5 under the action of the spring 10, and the block 13 will be re-stored into the storage groove 2. The purpose of extension is achieved, and the function of detecting electrical measurement modules with branches of different lengths is realized, which effectively improves the convenience of operation of the electrical measurement module detection and effectively improves the detection efficiency of the electrical measurement module.

[0029] During installation, the internal threaded tube 18 is aligned with the external threaded tube 16, and then the hexagonal disk 17 is rotated. When the hexagonal disk 17 rotates, the internal threaded tube 18 is driven to rotate, and when the internal threaded tube 18 rotates, the No. 1 limit ring 20 is driven to rotate under the No. 2 limit ring 21 through the connecting tube 19. At this time, since the bellows 5 and the sleeve 6 are installed under the fixed ring 4, and the fixed ring 4 is rotatably arranged outside the connecting tube 19 through the No. 2 limit ring 21, when the internal threaded tube 18 rotates, it will not drive the bellows 5 and the sleeve 6 to rotate, thereby avoiding torsion of the signal line 12, and when the internal threaded tube 18 rotates, it will be arranged on the outside of the external threaded tube 16 through the threaded sleeve, so as to facilitate installation and effectively ensure the normal detection and use of the electrical measurement module in this scheme.
