[0031] When the electrical elements are connected, the two fixing plates 55 are manually separated, the two fixing grooves 56 combined to form the threading hole are separated, at this time, the electric wire 4 is conveniently threaded from the threading hole, after the electric wire 4 is connected with the electrical elements, the two fixing plates 55 are close to each other until the threading hole stably clamps the electric wire 4, the fixing of the electric wire 4 is completed, the electric wire 4 is more orderly in the box 1, the installation of the electric wire 4 is more beautiful, and the installation and dismounting of the electrical elements 3 are more convenient and simple.

[0033] It should be noted that two first return springs 57 are symmetrically arranged on the outer circumferential side of the guide rod 53, one end of the two first return springs 57 is respectively connected to the opposite sides of the sliding groove 52, and the other end of the two first return springs 57 is respectively connected to the side surface of the two sliding blocks 54. In the initial state, the first return spring 57 is in the elongated state. When the electric wire 4 needs to pass through the threading hole, the two fixed plates 55 are manually separated, at which time the two first return springs 57 are in the compressed state. After the electric wire 4 passes through the threading hole, the fixed plate 55 is loosened, and the two first return springs 57 in the same guide groove respectively hold the two sliding blocks 54 close to each other, and the two sliding blocks 54 respectively push the two fixed plates 55 close to each other, until the threading hole can stably clamp the electric wire 4.

[0034] In an embodiment of the utility model, two vertical sliding rails are symmetrically arranged on the inner side of the box body 1. Specifically, the length direction of the vertical sliding rail is consistent with the height direction of the box body 1, and the side of the vertical sliding rail close to the fixed frame 51 is provided with a lifting groove 59. Two lifting blocks 58 are symmetrically arranged on the two sides of the fixed frame 51, and the lifting block 58 is slidingly connected with the lifting groove 59 of the vertical sliding rail. Through the sliding cooperation of the lifting block 58 and the lifting groove 59, the fixed frame 51 can be freely slid up and down in the box body 1. During the process of the fixed frame 51 sliding up and down in the box body 1 along the length direction of the lifting groove 59, the threading hole can straighten the bent electric wire 4, so as to solve the problem of the bending of the electric wire 4, improve the beauty of the installation of the electric wire 4, and make the electric wire 4 more orderly and orderly in the box body 1, and the installation and disassembly of each electrical element 3 are more convenient.

[0035] In addition, a plurality of fixing holes 61 are arranged in the extension direction of the lifting groove 59 on one side of the vertical sliding rail, the side surface of the lifting block 58 is inserted with a fixing rod 60, the first end of the fixing rod 60 is matched with the fixing hole 61, the fixing rod 60 is matched with the fixing hole 61 at different height positions according to the requirement, the fixed frame 51 can be stopped at different heights in the box body 1 as a whole, and preferably, the number of the fixing holes 61 on each vertical guide rail is three, and the two fixing holes 61 at the same height on the two vertical guide rails form a group, and the two fixing rods 60 on the fixed frame 51 are simultaneously connected with the corresponding fixing holes 61, so as to horizontally fix the fixed frame 51 in the box body 1.

[0036] The side of the lifting block 58 is provided with an assembly cavity, a sliding plate 62 is slidably arranged in the assembly cavity, the sliding plate 62 is connected to the second end of the fixed rod 60, and the fixed rod 60 can stably stretch and retract in the assembly cavity through the sliding cooperation of the sliding plate 62 and the assembly cavity, thereby ensuring that the fixed block can be accurately matched with the fixed hole 61. At the same time, the second reset spring 63 is arranged in the assembly cavity, one end of the second reset spring 63 is connected to the side of the assembly cavity away from the fixed rod 60, and the other end of the second reset spring 63 is connected to the sliding plate 62. When the fixed rod 60 moves to the coaxial position of the fixed hole 61, the fixed rod 60 can be accurately inserted into the fixed hole 61 under the top-holding action of the second reset spring 63, thereby ensuring the sensitive cooperation of the fixed rod 60 and the fixed hole 61.

[0037] It should be noted that the fixed hole 61 penetrates one side of the vertical sliding rail, and when the fixed rod 60 is inserted into the corresponding fixed hole 61, the fixed rod 60 can be pushed into the assembly cavity by a pin or a jacking rod, so that the fixed rod 60 is separated from the fixed hole 61, and the fixed rod 60 loses the limiting position of the fixed frame 51. At this time, the lifting block 58 can freely slide in the lifting groove, that is, the fixed frame 51 can move up and down in the box body 1. In addition, the inner diameter of the fixed hole 61 is greater than the outer diameter of the fixed rod 60, so as to ensure that the end of the fixed rod 60 can freely enter the fixed hole 61.

[0038] Preferably, the fixed hole 61 is a threaded hole, and the fixed hole 61 is threadedly connected with a plugging screw. When the fixed rod 60 does not need to be inserted into the corresponding fixed hole 61, the plugging screw is forwardly screwed in the corresponding fixed hole 61, and the end of the plugging screw is flush with the side of the lifting groove 59, which does not affect the free sliding of the lifting block 58 in the lifting groove 59. When the fixed rod 60 needs to be inserted into the corresponding fixed hole 61, the plugging screw in the corresponding fixed hole 61 is removed or screwed out to a certain length in the reverse direction, so that the fixed rod 60 can be inserted into the corresponding fixed hole 61, thereby locking the fixed frame 51 at the corresponding height position. On the other hand, for ordinary fixed holes 61, the fixed rods 60 on both sides of the fixed frame 51 need to be pushed out of the corresponding fixed holes 61, and it is difficult for one person to complete the operation while holding the fixed frame 51 with one hand. By arranging the fixed hole 61 as a threaded hole, the worker can hold the fixed frame 51 with one hand and push the fixed rod 60 out of the fixed hole 61 by screwing the plugging screw with the other hand, which is more convenient to use.
