[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 4 As shown, in this embodiment, a special grounding connection structure includes a mounting frame 1, which is characterized in that: a fastening component 7 is installed in the mounting frame 1, the fastening component 7 includes a socket 701 opened on one side of the top outer wall of the mounting frame 1, a fastening rod 702 is slidably inserted in the socket 701, the area of ​​the top end of the fastening rod 702 is larger than the area of ​​the socket 701, and mounting grooves 703 are opened on the inner walls on both sides of the fastening rod 702, and two clamping blocks 704 are slidably connected inside the mounting groove 703, and the two clamping blocks 704 are symmetrically arranged, and the sides of the two clamping blocks 704 close to each other are rotatably connected to a connecting plate 705, and the two connecting plates 705 are rotatably connected to the same connecting frame 706, and the bottom outer wall of the connecting frame 706 and the bottom inner wall of the mounting groove 703 are fixedly connected to the same spring 2 707.

[0024] A pull rod 708 is fixedly connected to the outer wall at the bottom of the connecting frame 706 , and the pull rod 708 is slidably inserted into the fastening rod 702 . The inner walls on both sides of the insertion hole 701 are respectively provided with card slots adapted to the two card blocks 704 .

[0025] When the clamping plate 705 is folded, the two clamping blocks 704 can be pressed into the mounting groove 703, and the two connecting plates 705 can be folded. The two can compress the spring 2 707 to shorten, and when the spring 2 707 is moved to the clamping groove position set in the socket 701, the two connecting plates 705 can be restored to the inclination due to the unrestricted spring 2 707, and the two clamping blocks 704 can enter the two clamping holes. Under the restriction of the clamping blocks 704, the wire nose 4 can be firmly restricted to the top wall of the mounting frame 1. If the clamping rod 702 needs to be removed, one end of the pull rod 708 can be pulled downward, which drives the connecting frame 706 to move synchronously. The connecting frame 706 can drive the two clamping blocks 704 to retract into the mounting groove 703 through the connecting plate 705, and the clamping rod 702 is no longer restricted, and can be easily taken out by pushing the clamping rod 702 upward.

[0026] like Figure 1 As shown, the external sliding sleeve of the fastening rod 702 is provided with a wire nose 4, and the area of ​​one end of the wire nose 4 is smaller than the area of ​​the top end of the fastening rod 702, and a soft copper stranded wire 5 is fixedly installed inside the wire nose 4.

[0027] like Figure 2 and Figure 3As shown, a connecting component 6 is installed inside the mounting frame 1, and the connecting component 6 includes a limiting slide groove 601 opened inside the mounting frame 1, and a movable hoop 602 is slidably connected in the limiting slide groove 601, and a fixed hoop 2 matched with the movable hoop 602 is fixedly connected to the outer wall at one end of the mounting frame 1, and a plurality of springs 604 are fixedly connected to the movable hoop 602 and the inner wall of one side of the mounting frame 1, and a plurality of limiting rods 603 are fixedly connected to the inner walls on both sides of the limiting slide groove 601, and the movable hoop 602 is slidably sleeved on the outside of the plurality of limiting rods 603.

[0028] An extension block 605 is provided at one end of the top and bottom outer walls of the movable hoop 602. Press the two extension blocks 605 respectively with two fingers and press the outer wall of the mounting frame 1 with another finger, so that it is easier to use force when moving the movable hoop 602.

[0029] The movable hoop 602 is driven by the extension block 605 to slide along the limiting slide groove 601. At this time, the thrust of the spring 1 604 is also offset and shortened, and then the external connecting column is located between the fixed hoop 2 and the movable hoop 602. After the restriction of the movable hoop 602 is released, the spring 1 604 will resume its lengthening, and the movable hoop 602 will be pushed to squeeze the external connecting column, and it can be fixed by cooperating with the fixed hoop 2, so that the device can adapt to the grounding connection work of different motors.

[0030] like Figure 1 As shown, a same reinforcing bolt 3 is installed between the fixed hoop 2 and the movable hoop 602, and the fixed hoop 2 and one end of the movable hoop 602 are connected by the reinforcing bolt 3, so as to further reinforce them.

[0032] The utility model provides a special grounding connection structure, and the specific working principle is as follows:

[0033] When the device is working, two fingers are respectively pressed on the two extension blocks 605, and another finger is against the outer wall of the mounting frame 1, so that it is easier to use force when moving the movable hoop 602. The movable hoop 602 is driven by the extension block 605 to slide along the limiting slide groove 601. At this time, the thrust of the spring 1 604 is also offset and shortened, and then the external connecting column is placed between the fixed hoop 2 and the movable hoop 602. After releasing the restriction of the movable hoop 602, the spring 1 604 will resume its lengthening, and the movable hoop 602 will be pushed to squeeze the external connecting column, and can be fixed with the fixed hoop 2, so that the device can adapt to the grounding connection of different motors. Finally, the fixed hoop 2 and one end of the movable hoop 602 are connected with the reinforcing bolt 3, so as to further reinforce it, and then one end of the wire nose 4 is placed on the top of the jack 701, and then the fastening rod 70 2 is inserted into the socket 701, and the two clamping blocks 704 will move toward the inside of the installation slot 703 under the restriction of the socket 701, and the two connecting plates 705 will also fold. The two can compress the second spring 707 to shorten through the connecting frame 706. When it moves to the clamping slot position set in the socket 701, the second spring 707 is not restricted so that the two connecting plates 705 restore the inclination, and the two clamping blocks 704 will also enter the two clamping holes. Under the restriction of the clamping blocks 704, it can ensure that the wire nose 4 is firmly restricted to the top wall of the installation frame 1. If it is necessary to remove the fastening rod 702, just pull one end of the pull rod 708 downward, which drives the connecting frame 706 to move synchronously. The connecting frame 706 can drive the two clamping blocks 704 to retract into the installation slot 703 through the connecting plate 705, and the fastening rod 702 is no longer restricted. It can be easily taken out by pushing the fastening rod 702 upward.
