[0017] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0018] like Figure 1-2 As shown, a connection plate bolt quick installation device comprises a handheld bracket 1 and a reduction motor 2 fixedly mounted on the handheld bracket;

[0019] It also includes an axle tube 3, which is tilted, and axle forks 4 are fixed at both ends of the axle tube. An upper rotating shaft and a lower rotating shaft are rotatably mounted on the handheld bracket. The upper rotating shaft is fixedly connected to an upper flange fork 5, and the lower rotating shaft is fixedly connected to a lower flange fork 6. The two axle forks are respectively connected to the upper flange fork and the lower flange fork through a cross-axis universal joint assembly 7.

[0020] The output shaft of the reduction motor is fixedly connected to the upper rotating shaft, the reduction motor circuit is connected with a forward and reverse rotation button, the lower rotating shaft is fixedly connected to a bit holder 8, and a bit 9 is installed on the bit holder.

[0021] In this way, the hand-held bracket is set to avoid the pipeline 11 and avoid interference with the pipeline. When in use, the bit is installed through the bit holder, and the reduction motor drives the bit holder to rotate through the shaft tube and the cross shaft universal joint assembly structure to drive the bit to rotate, and the bit drives the bolt to rotate to achieve the quick connection of the two connecting plates.

[0022] Before connection, the nut 10 is embedded in one of the connection plates and fixed in the connection plate. The shaft tube, the cross shaft universal joint assembly, the shaft fork, the upper flange fork and the lower flange fork are all existing structures and can realize rotation transmission.

[0023] During implementation, a diagonal brace 12 is fixed on the handheld bracket, and the shaft tube is connected to the diagonal brace through a bearing, so as to better support the shaft tube and improve stability.
