[0005] The pole body can be clamped by the pole ring to avoid the pole body from being skewed. During installation, press the two limit blocks and make the limit blocks in the limit groove. At this time, the limit spring is squeezed. When the pole body slides to a suitable position, the limit block can slide out of the limit groove and slide into the limit opening under the elastic force of the limit spring, thereby completing the fixing operation of the pole body. The two are in a clamping connection to avoid separation during welding. Then the rotating block is rotated. The rotation of the rotating block can rotate the rotating shaft.

The rotation of the sleeve can make the threaded rod move in the inner wall of the sleeve, so that the pole body and the cover plate can fit more closely. Therefore, the effect of ensuring the conductivity between the cover plate and the pole can be achieved.

[0006] Preferably, limiting grooves are provided on both sides of the pole body, and a limiting spring is fixedly connected to an inner wall of one side of the limiting groove. The limiting spring is fixedly connected to the limiting block, and a sliding fit is formed between the limiting block and the inner wall of the limiting groove.

[0008] Preferably, an insulating pad is fixedly connected to the inner wall of the bottom of the connecting groove, and the insulating pad is made of rubber. A cavity is opened in the insulating pad. The setting of the insulating pad can act in the opposite direction to the connecting block when the connecting block squeezes it, and promote a tighter connection between the pole body and the cover plate.

[0009] Preferably, the locking mechanism includes two threaded rods respectively fixedly connected to the two sides of the bottom of the cover plate, and the two sides of the top of the insulating plate are rotatably connected with sleeves through bearings. The inner wall of the sleeve is connected to the threaded rod through a threaded connection. The arrangement of the sleeve can cause relative movement between the sleeve and the threaded rod when it is rotated, so that the insulating plate can be fixed.

[0010] Preferably, the bottom of the sleeve is fixedly connected with a rotating shaft, and the bottom of the rotating shaft is fixedly connected with a rotating block. The setting of the rotating block can make the rotating shaft rotate when rotating, and the rotation of the rotating shaft can make the sleeve rotate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The pole body can be clamped by the pole ring to avoid the pole body from being skewed. During installation, press the two limit blocks and make the limit blocks in the limit groove. At this time, the limit spring is squeezed. When the pole body slides to a suitable position, the limit block can slide out of the limit groove and slide into the limit opening under the elastic force of the limit spring, so that the fixing operation of the pole body can be completed. The two are in a clamping connection to avoid separation due to welding. Then rotate the rotating block. The rotation of the rotating block can rotate the rotating shaft. The rotation of the rotating shaft can rotate the sleeve. The rotation of the sleeve can make the threaded rod move in the inner wall of the sleeve, so that the pole body and the cover plate can be more closely fitted. Therefore, the effect of ensuring the conductivity between the cover plate and the pole can be achieved.

[0013] 2. The connecting block can slide in the inner wall of the connecting groove. When the insulating plate is installed, the limit between the two can prevent the insulating plate from moving laterally. The insulating pad can act in the opposite direction to the connecting block when the connecting block squeezes it, and make the connection between the pole body and the cover plate tighter. The sleeve can move relative to the threaded rod when it rotates, so that the insulating plate can be fixed. BRIEF DESCRIPTION OF THE DRAWINGS
