Thereby guaranteed the whole outward appearance of black subassembly and for the black demand, guaranteed the product percent of pass.

In this embodiment, handle 1 adopts cylindrically to make things convenient for operating personnel to grip, and carry out burnishing and polishing to handle 1 and pressing member 2 and handle, eliminate the burr that presses the frock surface, avoid pricking operating personnel.

Further, the handle 1 is detachably connected with the pressing piece 2. Thereby facilitating a quick replacement of the press 2. In the present embodiment, the handle 1 and the pressing member 2 are connected by a screw.

Further, the pressing pieces 2 are provided in plural, the plural pressing pieces 2 are respectively adapted to be fitted with bus bars of different models, and the handle 1 can be connected to any one of the pressing pieces 2. Therefore, the pressing tool can press different types of bus bars, and the application range of the pressing tool is expanded.

In this embodiment, the pressing member 2 with various specifications is prepared, and because the pressing member 2 is in threaded connection with the handle 1, the corresponding pressing member 2 can be replaced quickly according to the type of the bus bar, so that the situation that the glass plate is crushed due to the fact that the pressing member 2 is not matched with the bus bar type is avoided.

Alternatively, as shown in fig. 1-2, the pressing member 2 includes a pressing portion 22 and a connecting portion 23, the pressing portion 22 is fixedly disposed at one end of the connecting portion 23, the handle 1 is detachably connected to the other end of the connecting portion 23, and the pressing surface 21 is disposed at one end of the pressing portion 22 away from the connecting portion 23. By providing the connecting portion 23, the connection of the handle 1 and the pressing member 2 is facilitated, and a buffer zone is provided between the handle 1 and the pressing portion 22.

In the present embodiment, one end of the pressing portion 22 and the connecting portion 23 are fixed together by welding, and the other end of the connecting portion 23 and the handle 1 are screwed together.

Further, the pressing portion 22 is perpendicular to an end surface of the connecting portion 23 connected to the pressing portion 22. Through making pressing portion 22 and connecting portion 23 perpendicular setting to make things convenient for operating personnel according to the vertically characteristic, hold handle 1 and press repeatedly the protruding arch of bending of same position on the busbar, reach the bellied effect of bending of the busbar that flattens.

Alternatively, as shown in fig. 3, the handle 1 is a hollow cylinder. Through adopting hollow barrel structure with handle 1, greatly reduced handle 1's weight. Because the operator often needs to work for many hours in succession, the burden on the operator can be greatly reduced by using the hollow handle 1.

In this embodiment, the handle 1 is a hollow cylinder with two ends penetrating. In other embodiments, the handle 1 may be a cylinder, and a blind hole may be cut at one end to reduce the weight of the handle 1 according to the weight reduction requirement.
