The assembling mode of the connecting piece of the invention is as follows:
step 1: embedding the embedded part 1 into a plate body; if the embedded part 1 is provided with a large hole as shown in CN201910534170.0, the embedded part 1 can be embedded into the plate body by the bracket, and if the embedded part 1 is not provided with a large hole, the embedded part 1 is assembled with the head 9 of the pull rod 2 in advance, and the head 9 of the pull rod 2 and the embedded part 1 are required to be embedded into the plate body together;
step 2: inserting the pull rod 2 into the shell 3, and placing the movable block 4 below the second expansion part 7; the shell 3 is inserted into the side edge of the other plate body, and a hole corresponding to the threaded hole 11 is formed in the panel of the plate body;
step 3: inserting the head 9 of the tie rod 2 into the embedment 1 of step 1 (this step is omitted if the head 9 and the embedment 1 are preassembled);

Therefore, one-time operation is realized, the purpose that the first expansion part 6 and the second expansion part 7 are simultaneously locked is realized, and meanwhile, as the movable block 4 moves upwards integrally, the first expansion part 6 and the plate body are simultaneously contacted, the occlusion is more uniform, and the locking device is more reliable when being used for a long time.
The movable block 4 and the pull rod 2 of the embodiment have no long-stroke threads, the structure is simple, only the screw 5 is needed during installation, and the installation is very convenient.
One of the preferred schemes of this embodiment is: the device also comprises an elastic reset piece 12, wherein one end of the elastic reset piece 12 is in abutting contact with the tail end of the shell 3, and the other end of the elastic reset piece is in abutting contact with the tail part 10 of the pull rod 2;
when the pull rod 2 moves to the preset position, the elastic restoring member 12 is compressed.
The elastic restoring member 12 has the function that when the connecting member is required to be disassembled, the screw 5 is loosened, the elastic restoring member 12 pushes the pull rod 2 in the opposite direction, and the first expansion part 6 and the second expansion part 7 are restored at the same time. An important function of the resilient return member 12 is to facilitate removal.
One of the preferred schemes of this embodiment is: a limiting piece is arranged in the shell 3 or on the movable block 4 and is used for limiting the pull rod 2 not to be ejected out of the shell 3 when the elastic reset piece 12 is received.

When the pull rod 2 is pulled to move away from the embedded part 1, the head 9 expands the first expansion part 6. In practical applications, the head 9 does not have to be selected to have a truncated cone shape, for example, a disc-shaped or block-shaped head 9 is all that is required, and as long as the first expansion part 6 can be exploded, the alternative of the present invention is all that is required.
Preferably, the tail portion 10 is a tapered end portion, the elastic restoring member 12 is a spring, one end of the spring contacts with the tail end of the housing 3, and the tail portion 10 is inserted into the other end of the spring.

Preferably, the second expansion part 7 is formed by two expansion plates which are arranged oppositely, one side edge of the expansion plates is connected with the shell 3, and the other side edges are suspended. Because the expansion plate is pulled by the movable block 4, the expansion plate needs to be manufactured into a cantilever structure so that the whole expansion plate is synchronously expanded when the movable block 4 ascends; the structural design can also lead the engagement of the expansion plate and the plate to be synchronous and uniform, and the service life of the expansion plate is longer and the expansion plate is not easy to loosen in the long-time connection process.
And compared with the expansion structure shown in CN201910534170.0, the expansion plate in this embodiment is a synchronous expansion structure, and the expansion structure in CN201910534170.0 is not a cantilever structure, and on one hand, the expansion plate cannot be synchronously expanded, and on the other hand, even if the side plate connecting piece moves to the limit position, the root of the expansion plate cannot be completely expanded due to the fact that the expansion plate is not a cantilever structure.
In the present embodiment, the housing 3 is formed by connecting a left housing 15 and a right housing 16; an expansion plate is arranged on each of the left shell 15 and the right shell 16; a gap at least for the screw 5 to pass through is arranged between the two expansion plates.
