The clamping member 200 includes a clamping plate 201 and an abutting block 203. The clamping plate 201 is provided with an abutting block 203. The abutting block 203 is movably plugged with the second plugging groove 104. A side of the abutting block 203 away from the clamping plate 201 is provided with an inclined surface.

[0024] The plug-in assembly 300 further includes a knocking platform 302. A plurality of knocking platforms 302 are disposed on the sliding seat 301. The knocking platforms 302 extend through the plug-in slot 103. By applying an impact along the extending direction of the sliding seat 301 on the knocking table 302 , the sliding seat 301 is moved in the sliding cavity 102 by knocking the knocking table 302 .

A mounting tube 410 is provided at each end of the base frame 413. A connecting seat 402 is provided at each end of the connecting column 401. The connecting seats 402 are both provided with a threaded column 403. The mounting tube 410 is plugged into one of the threaded columns 403. The threaded column 403 at the bottom end of the connecting column 401 passes through the mounting tube 410 and is threadedly connected with a positioning nut 412. The connection column 401 is connected to the base frame 413 by using the installation tube 410, and the installation frame 101 is fixed by the connection column 401 and the base frame 413.

[0029] The fixing mechanism 400 further includes a positioning cylinder 411, which is inserted into the inner side of the mounting cylinder 410 and is sleeved with the threaded column 403. A cylinder is provided on one side of the positioning nut 412 and is inserted into the inner side of the mounting cylinder 410. One end of the positioning cylinder 411 is inserted into the connecting seat 402 and the other end is in contact with the cylinder of the positioning nut 412. The mounting tube 410 is fixedly connected to the connecting column 401 by the cooperation of the positioning nut 412 , the positioning tube 411 and the connecting seat 402 .

The second connecting arm 407 is locked on the object to be fixed through the U-shaped hoop 409 and the third connecting arm 408, thereby fixing the main assembly 100 and the bus duct body 500.

[0033] The specific implementation method is as follows: the clamping member 200 is placed on both sides of the installation groove 105, and then the bus duct body 500 is placed between the two installation grooves 105, and then the plug-in assembly 300 is inserted into the sliding cavity 102, and the sliding seat 301 is continuously moved in the sliding cavity 102 by knocking the knocking table 302. During the process, the self-locking piece 305 locks the plug-in assembly 300 in the sliding cavity 102 in one direction and cannot retreat. After the sliding seat 301 is inserted into the sliding cavity 102 with the self-locking piece 305, the sliding seat 301 retreats out of the sliding cavity 102, which causes the self-locking piece 305 to swing and tend to become a vertical state, and the space provided by the sliding cavity 102 and the connecting groove 303 is not enough for it to stand vertically, resulting in locking; During this period, the V-shaped plate 307 abuts and pushes the abutment block 203 to move, so that the abutment block 203 brings the clamping plate 201 close to and locks the bus duct body 500, connects the fixing mechanism 400 with the bottom end of the main component 100, and then locks the connecting arm 2 407 on the object to be fixed through the U-shaped hoop 409 and the connecting arm 3 408, thereby fixing the main component 100 and the bus duct body 500.

[0034] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
