[0002] For example, the rigid catenary busbar jaw expander with the patent publication number CN216002282U includes a main body and an auxiliary main body; one end of the main body is hinged to one end of the auxiliary main body to form the hinged end of the expander; the cross-section of the other end of the auxiliary main body is L-shaped, and the shape of the other end of the main body is symmetrical to the L-shaped end of the auxiliary main body, and the two ends form the opening end of the expander. The cross-section size of the opening end is configured such that the opening end can be embedded into the jaws of the busbar; a threaded hole is provided on the side surface of the main body, and a top support member is screwed into the threaded hole, and the length of the top support member is greater than the minimum vertical distance between the side surface of the main body and the side surface of the auxiliary main body. The structure is simple and the operation is convenient, which can reduce the installation or maintenance time.
[0003] However, during the use of the above device, due to the setting of the internal main body and auxiliary main body, during use, due to the connection in the form of hinge, the expansion angle is easily restricted, reducing the working efficiency.

[0020] As Figures 1-3 shown, the present invention provides a technical solution: a busbar partial expander, including a support mechanism 1. The support mechanism 1 includes a first support plate 101. An expansion mechanism 2 is arranged on the top of the support mechanism 1. The expansion mechanism 2 includes a fixing plate 201. The first support plate 101 is connected to the fixing plate 201. A lifting component and an expansion component are arranged on one side of the fixing plate 201. The expansion component includes a sliding plate 205. A second support plate 207 is fixedly connected to the top of the sliding plate 205. A connecting plate 208 is fixedly connected to one side of the second support plate 207. A clamping plate 209 is rotatably connected to one side of the connecting plate 208.
[0021] As Figure 2 shown, a through hole is opened on one side of the top of the first support plate 101. A connecting shaft 102 is rotatably connected in the through hole. One end of the connecting shaft 102 is rotatably connected to a rotating plate 103. Through holes are opened on one side of the top of the first support plate 101 and the rotating plate 103. A screw rod 104 is slidably connected in the through hole. Lifting rings 105 are rotatably connected to both ends of the screw rod 104. A base 106 is fixedly connected to one end of the screw rod 104.
[0022] It should be noted that during the use process, first, according to the requirements, rotate the rotating plate 103 to a suitable angle through the connecting shaft 102 of the first support plate 101, and then manually rotate the lifting ring 105 to lift the equipment under the action of the screw rod 104 and the base 106. The structure of the support mechanism 1 can be quickly assembled and adjusted in height and angle according to needs, improving the operation flexibility.
[0023] As Figure 3As shown in the figure, the lifting component includes a bidirectional lead screw 202 which penetrates through the fixed plate 201 and is rotatably connected thereto. A servo motor 203 is installed on the top of the fixed plate 201, and the output end of the servo motor 203 is connected to the bidirectional lead screw 202.
