[0003] According to patent No. CN202110296122.X, a copper busbar fixing seat with variable spacing is disclosed, including a fixing seat main body, and a plurality of fixing through holes are arranged at intervals on the fixing seat main body; the fixing seat main body includes a first fixing plate and a second fixing plate connected to each other, and the fixing through holes include a first fixing half-hole and a second fixing half-hole, and each first fixing half-hole is respectively arranged at intervals at the end of the first fixing plate connected to the second fixing plate, and each second fixing half-hole is respectively arranged at intervals at the end of the second fixing plate connected to the first fixing plate; the first fixing plate is provided with at least one limit block, and the limit block is provided with a connecting screw hole; the second fixing plate is provided with at least one limit groove, and the bottom of the limit groove is provided with a connecting through hole, and the connecting through hole respectively connects the limit groove and an end of the second fixing plate away from the first fixing plate; the fixing seat main body also includes at least one connecting screw.

[0004] The above scheme still has certain technical defects in actual use. When adjusting the upper fixing plate, it is necessary to adjust multiple connecting screws at the same time to achieve the adjustment function. Otherwise, the upper fixing plate is prone to tilt, which will cause damage to the threads of the connecting screws and affect subsequent use. For this reason, we propose a new copper busbar fixing seat. Utility Model Content

[0007] Preferably, a limiting block is fixedly provided at the bottom of the threaded sleeve, a limiting groove is provided on the inner bottom surface of the movable groove, and the limiting block extends into the interior of the limiting groove and is slidably connected to the inner wall thereof.

[0008] Preferably, one end of the screw rod extends to the outside of the lower fixing plate, and the end of the screw rod extending to the outside of the lower fixing plate is fixedly connected to a knob.

[0009] Preferably, a spacer is provided in the middle of the screw, and the spacer is sleeved on the outer circumference of the screw and fixedly connected thereto.

[0010] Preferably, an upper plug plate is arranged on the inner side of the upper fixed plate, a compression spring is arranged on the top of the upper plug plate, and two ends of the compression spring are fixedly connected to the upper plug plate and the upper fixed plate respectively.

[0011] Preferably, a lower plug plate is provided on the inner side of the lower fixing plate, and the lower plug plate is fixedly connected to the lower fixing plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The movable plate is driven by using a screw, a threaded sleeve, a movable connecting seat and a movable rod to push it up and down, and the extension plate is used to transmit power to the upper fixed plate, so as to achieve the purpose of adjusting the distance between the upper fixed plate and the lower fixed plate. This design makes it possible to achieve the adjustment function by turning a single knob alone, thereby avoiding the upper fixed plate from tilting.

[0014] 2. By setting a limit groove inside the movable groove, cooperating with the limit block at the bottom of the threaded sleeve, and utilizing the limit sliding connection of the limit block inside the limit groove, the threaded sleeve can be limited to prevent the threaded sleeve from rotating with the screw and affecting the stability of the adjustment effect.
