as shown in fig. 4, one end of the adjusting block 17, which is close to the telescopic sleeve 8, is provided with an inclined surface matched with the inclined surface 15, the inclined surface of the adjusting block 17 is consistent with the inclined direction of the inclined surface 15, one side of the telescopic sleeve 8, which is close to the matching ring 10, is provided with a saw tooth 16 matched with the inclined surface of the adjusting block 17, the matching sleeve 9, the telescopic sleeve 8 and the guide sleeve 7 are all on the same axis, the thickness of the inclined surface of the adjusting block 17 is larger than that of the saw tooth 16, and on a section passing through the axis of the second circular cavity, the inner surface of the inclined surface of the adjusting block 17 can be flush with the inner surface of the saw tooth 16, and the outer surface of the inclined surface of the adjusting block 17 can be flush with the outer surface of the inclined surface 15, so that the inclined surface of the adjusting block 17 can be simultaneously contacted with the saw tooth 16 and the inclined surface 15;
when the matching sleeve 9 slides to the guide sleeve 7, the part of the inclined surface of the adjusting block 17, which is close to the axis of the matching sleeve 9, is firstly contacted with the saw teeth 16, and the pressure is applied to the telescopic sleeve 8 through the contact part of the saw teeth 16, so that the telescopic sleeve slides to the direction of the guide sleeve 7 against the elastic force of the return spring 6, and when the inclined surface of the adjusting block 17 slides to the end part of the guide sleeve 7, the part of the inclined surface of the adjusting block 17, which is far away from the axis of the matching sleeve 9, is contacted with the inclined surface 15;
the sawtooth 16 mainly comprises tooth tips, tooth bottoms and tooth surfaces which are connected end to end around the telescopic sleeve 8, the number of the tooth bottoms is identical to that of the partition boards, and because the telescopic sleeve 8 and the guide sleeve 7 are fixed in circumferential positions, when the telescopic sleeve 8 drives the tooth bottoms to slide to the position of the chamfer 15 of the partition boards, the tooth bottoms are positioned in the chamfer 15 and are close to the top of the chamfer 15, and when the adjusting block 17 is inserted from the matching ring 10, the tooth bottoms of the sawtooth 16 are just aligned with the top of the chamfer of the adjusting block 17;
as shown in fig. 6 to 10, a schematic diagram of a state process of energizing the contact point 20 and the contact block 18 through the resistor block 11 is shown after the mating sleeve 9 is inserted into the connecting slot 4 and the angle of the mating sleeve is adjusted for the first time by the angle adjusting assembly, and the specific process is as follows:
the hand-held grip 3 inserts the adjusting block 17 on the matching sleeve 9 in alignment with the inlet groove on the matching ring 10, continuously pushes the matching sleeve 9 into the second circular cavity completely, and the outer surface of the adjusting block 17 is matched with the connecting groove 4 to limit the matching sleeve 9 to slide along the axial direction;
when the matching sleeve 9 slides to the position that the inclined surface end part of the adjusting block 17 is in contact with the tooth bottom of the saw tooth 16, the matching sleeve 9 can give thrust to the telescopic sleeve 8 to enable the telescopic sleeve 8 to slide towards the guide sleeve 7, and the reset spring 6 is contracted by the extrusion force of the telescopic sleeve 8;
when the matching sleeve 9 drives the telescopic sleeve 8 to slide to the contact position of the tooth bottom and the bevel 15, the inclined surface of the adjusting block 17 is also contacted with the bevel 15 at the same time, the contact position is positioned at the position of the bevel 15 close to the end part, when the matching sleeve 9 is continuously pushed, the inclined surface of the adjusting block 17 is influenced by the pushing force to slide along the bevel 15 due to the fixed position of the guide sleeve 7, so that the matching sleeve 9 is driven to rotate, and meanwhile, the inclined surface end part of the adjusting block 17 also can give the tooth surface pressure of the saw teeth 16, so that the telescopic sleeve 8 continuously slides towards the direction far away from the matching ring 10;
because the guide sleeve 7 is of a cylindrical sleeve structure, the outer ring of the guide sleeve is matched with the connecting groove 4, and the saw teeth 16 and the bevel 15 are both in the rotation range of the adjusting block 17, the inclined surface of the matching sleeve 9 is always contacted with the bevel 15 and the saw teeth 16 of the telescopic sleeve 8 to be matched in the rotation process of the matching sleeve 9;
when the telescopic sleeve 8 slides until the tooth tips of the saw teeth 16 of the telescopic sleeve are contacted with the chamfer 15, the inclined surface of the adjusting block 17 slides over the tooth tips of the saw teeth 16 until the adjusting block 17 stops when the side surface of the adjusting block 17 slides to the position where the side surface of the adjusting block contacts with the side surface of the partition plate;
at the moment, when the handle 3 is released, the telescopic sleeve 8 can slide towards the direction of the matching ring 10 under the influence of the elasticity of the reset spring 6, the telescopic sleeve 8 also gives the acting force to the matching sleeve 9 to enable the telescopic sleeve 8 to slide towards the direction of the matching ring 10, and when the tooth bottoms of the saw teeth 16 on the telescopic sleeve 8 are separated from the guide sleeve 7, the inclined surfaces of the adjusting blocks 17 also slide into the tooth bottoms along the tooth surface ends of the saw teeth 16;
under the action of the elastic force of the return spring 6, the telescopic sleeve 8 finally pushes the adjusting block 17 to move to a position contacted with the resistor block 11, so that the contact block 18 is contacted with the resistor block 11, and at the moment, the elastic force of the return spring 6 is still larger than that of the pressure spring 19, so that the resistor block 11 also slides towards the matching ring 10 under the influence of pressure until the resistor block 11 is contacted with the side surface of the matching ring 10, so that one surface of the resistor block 11 away from the adjusting block 17 is contacted with the contact point 20, and the power wire 2 is communicated with the contact point 20 through the contact block 18 and the resistor block 11 to supply power to the concentrator 1;
through the matching of the bevel 15 and the inclined plane of the adjusting block 17, the rotation direction of the matching sleeve 9 is limited, so when the angle adjustment of the position of the contact block 18 is finished for the first time, the resistance block 11 between the contact block 18 and the contact point 20 is in the longest state, the resistance is larger, the current obtained by the contact point 20 through the resistance block 11 is the smallest, and the length of the resistance block 11 between the contact block 18 and the contact point 20 is shorter when the angle adjustment is repeated every time, so the current obtained by the contact point 20 is increased once when the angle adjustment is carried out once until the current obtained by the contact point 20 can enable the concentrator 1 to be started, so that the power supply current of the concentrator 1 can be safely and energy-effectively adjusted;
dividing the energizing positions of the contact block 18 and the contact point 20 into a plurality of equal parts, gradually increasing the energizing current between the contact block 18 and the contact point 20 by repeating the angle adjusting action, wherein the larger the angle of rotation of the matching sleeve 9 is, the shorter the length of the resistance block 11 between the contact block 18 and the contact point 20 is, the smaller the resistance is, so that the larger the current obtained by the concentrator 1 is;
when the matching sleeve 9 rotates 180 degrees, the matching sleeve automatically falls out of the inlet groove, and the former contact position is the position with the shortest distance between the contact block 18 and the resistance block 11 at the contact point 20;
when the contact block 18 is communicated with the contact point 20, the return spring 6 is not returned to the natural position, so that the extrusion force is still generated on the adjusting block 17, and the stability of the connection of the contact block 18 and the contact point 20 is improved;
as shown in fig. 2, in order to protect the concentrator 1 when overload of short-circuit current occurs, an electromagnet 5 is fixedly installed at one end of the connecting groove 4 away from the matching ring 10, a controller is installed in the concentrator 1, the controller is electrically connected with the contact point 20, the controller is suitable for energizing the electromagnet 5 when the current of the contact point 20 exceeds the rated range of the concentrator 1, and the telescopic sleeve 8 is made of magnetic materials;
when the power line 2 is short-circuited in the use process, the electromagnet 5 is electrified through the controller, the electromagnet 5 generates magnetism to attract the telescopic sleeve 8 to slide towards the electromagnet 5, the reset spring 6 is stressed and contracted, so that the adjusting block 17 loses the extrusion force of the telescopic sleeve 8 on the telescopic sleeve, the adjusting block 17 is pushed away from the matching ring 10 by the resistance block 11 under the action of the elastic force of the pressure spring 19, and the resistance block 11 is separated from the contact point 20, so that the concentrator 1 is protected from being burnt;
in order to enable the electromagnet 5 to be automatically powered off and reset after being electrified, an approaching photoelectric 12 is arranged in the telescopic sleeve 8, the approaching photoelectric 12 is electrically connected with a controller, a control power supply is arranged in the controller, whether the matching sleeve 9 is still in the connecting groove 4 is detected through the approaching photoelectric 12, when the electromagnet 5 is electrified, the matching sleeve 9 is taken out of the connecting groove 4 through rotating, and then the approaching photoelectric 12 loses a detection signal, so that the controller controls the electromagnet 5 to be powered off and the telescopic sleeve 8 is reset;
when the matching sleeve 9 is inserted into the connecting groove 4 again for power-on adjustment, the contact point 20 and the contact block 18 are gradually increased from the minimum current through adjustment, and a manual toggle switch is not needed for power-on reset.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
