4A, a connection board 123 is coupled to an upper portion of the lid 122, and a connection bracket 11 may be installed at one end of the connection board 123. It is possible to adjust the position of the fastening bracket 11 with respect to the lid 122 according to the design structure. Adjustment of the position of the fastening bracket 11 may be performed by adjusting the engagement position of the fastening bracket 11 with respect to the connection board 123 or changing the engagement position of the fastening bracket 11 with the lid 122 of the connection board 123. For example, the connection board 123 can be coupled to the cover 122 so that the coupling position can be adjusted by a sliding method.

The fastening bracket 11 is separated or joined to the electrode rail by an electrode fixing block 41 which can move up and down with respect to the lid 122. [ The electrode fixing block 41 may be configured to extend into the lid 122 and the pair of connecting electrodes 111 and 112 may be arranged to extend in different directions in the upper portion. And the engaging unit 42 may be disposed on the upper portion of the connecting board 123. [ The engaging unit 42 is inserted into a gap formed by the extending portion extending inwardly of the electrode rail from both sides of the electrode rail and the lower surface of the tunnel-shaped guide unit disposed on the inner wall of both side surfaces of the electrode rail So that the fastening bracket 11 is fixed to the electrode rail.

The engaging unit 42 may be shaped to extend on both sides of the circumferential surface of the cylindrical electrode fixing unit 41 in a rectangular shape while being fixed to the electrode fixing block 41. The electrode fixing block 41 can be made rotatable with respect to the connecting board 123 and the holding unit 42 can be rotated together with the rotation of the electrode fixing block 41. [ The electrode fixing block 41 may have a structure capable of moving up and down with respect to the connection substrate 123 by elastic means. Specifically, a resilient means such as a spring is disposed at a lower portion of the lid 121, so that the electrode fixing block 41 can be moved up and down by elasticity.

And the fixing piece 42a may be disposed on the side surface of the engaging unit 42. [ The moving plate 43 can be disposed above the connecting board 123 and the moving plate 43 can be moved up and down by the elastic means 452. [ The engaging unit 42 and the fixing member 42a are disposed on the upper surface of the moving plate 43 and the cylindrical electrode fixing block 41 can be arranged to penetrate the moving plate 43. [ A fixing member 462 in which a supporting plate 461 is disposed in the fastening housing 44 and connected to a lower portion of the electrode fixing block 41 and a connecting member 451 disposed in a lower portion of the moving plate 43, The resilient means 452 can be fixed to the housing.

The moving plate 43 having a relatively large disc shape as compared with the engaging unit 42 can not be inserted into the electrode rail. In this state, when the upward pressure is applied, the moving plate 43 descends downward, so that a clearance is formed between the moving plate 43 and the engaging unit 42, and the engaging bracket 11 can be rotated . When the fastening bracket 11 is rotated, the fastening unit 42 is rotated together with the fastening unit 42, so that a portion of the fastening unit 42 deviating from both sides of the circumferential surface of the cylindrical electrode fixing block 41 is rotated, As shown in FIG. In the fixed state, rotation of the fastening bracket 11 is prevented by the fastening piece 42a. The fixing piece 42a is fixed to the moving plate 43 and is moved up and down together with the moving plate 43. When the moving plate 43 is moved downward, Gaps may be formed between the upper surfaces of the first and second trenches 42a. The fixing piece 42a can be made to move up and down by the elasticity according to the design structure. The fixing piece 42a may have a rectangular shape in which one side has a curved shape and may have an extending length corresponding to the width of the open portion formed in the lower portion of the electrode rail. Due to such a shape, when the fastening bracket 11 is engaged with the electrode rail, the fastening piece 42a is located at the open portion, so that the fastening bracket 11 is prevented from rotating. Concretely, both short sides of the rectangle of the fixing piece 42a are brought into contact with both ends of the portion extending from the lower side to the inside of the electrode rail described above, so that the rotation of the fastening bracket 11 is prevented.

The fastening brackets 11 can be made of various structures that are joined to and separated from the electrode rails, and the present invention is not limited to the embodiments shown.
