Place the loading tray body 403 on the placement table 3, and align the docking hole groove 404 in the loading tray body 403 with the mounting hole body 31 on the placement table 3. Then, insert the plugging cylinder body 601 one by one, that is, insert the plugging cylinder body 601 from top to bottom. One end of the plugging cylinder body 601 is first inserted into the docking hole groove 404 on the loading tray body 403, and then passes through the mounting hole body 31 on the placement table 3 until the limit retaining ring 603 at the other end of the plugging cylinder body 601 contacts the loading tray body 403.

[0022] During the connection process, in order to ensure the connection stability of the plugging cylinder body 601, after inserting the plugging cylinder body 601, insert the connecting threaded column body 701 into the plugging cylinder body 601. During the insertion process of the connecting threaded column body 701, the connecting threaded column body 701 will drive the auxiliary structure, so that the fastening chuck 802 in the auxiliary structure is stuck in the corresponding fastening slot 501 in the docking hole groove 404. That is, the accommodating cavity 801 in the auxiliary structure is symmetrically arranged on the outer side wall of the plugging cylinder body 601, and the inner end of the accommodating cavity 801 is provided with an auxiliary slot. One end of the auxiliary slot is communicated with the accommodating cavity 801, and the other end of the auxiliary slot is communicated with the plugging cylinder body 601.

During this process, after the plug-in cylinder body 601 is inserted, if the positions of the receiving cavity 801 and the fastening slot 501 cannot be aligned, the fastening chuck 802 will not be clamped after being squeezed. At this time, the operator needs to rotate the plug-in cylinder body 601 while squeezing the movable insert 803 with the connecting threaded column body 701. When the fastening chuck 802 is aligned with a certain fastening slot 501 in the docking hole 404, the fastening chuck 802 is clamped with the fastening slot 501 at the corresponding position, realizing the stable position of the plug-in cylinder body 601, that is, the plug-in cylinder body 601 will not loosen and shift in the circumferential direction. Among them, a limiting retaining ring 603 is fixedly arranged on the outer side wall of one end of the plug-in cylinder body 601 in the connecting component, a connecting thread 602 is arranged on the outer side wall of the other end of the plug-in cylinder body 601, and the plug-in cylinder body 601 sequentially passes through the docking hole 404 and the mounting hole body 31; the internal thread fastening ring 604 is threadedly connected with the connecting thread 602 in a matching manner, and an auxiliary spring 606 is fixedly arranged at one end of the internal thread fastening ring 604, and a connecting ring body 607 is fixedly arranged at the other end of the auxiliary spring 606; an auxiliary convex head 605 is fixedly arranged on the end face of one end of the internal thread fastening ring 604, the auxiliary convex head 605 is inclined outwards, and the auxiliary convex heads 605 are arranged in an annular shape at equal intervals on the end face of the internal thread fastening ring 604.

[0024] One end of the plug-in cylinder body 601 with the connecting thread 602 passes through the mounting hole body 31 to reach the bottom side position of the placement table 3, and then the internal thread fastening ring 604 is threadedly connected with the connecting thread 602 on the plug-in cylinder body 601, and the internal thread fastening ring 604 is tightened, so that the auxiliary convex head 605 at one end of the internal thread fastening ring 604 contacts and presses against the bottom side of the placement table 3, that is, the connecting threaded column body 701 in the fastening component is inserted into the plug-in cylinder body 601 in a matching manner, and an auxiliary handle 702 is fixedly arranged at one end of the connecting threaded column body 701, and an annular auxiliary slope is arranged at the edge side position of the other end of the connecting threaded column body 701, and the connecting threaded column body 701 is threadedly connected with the docking thread groove 706 in the locking cap body 703 in a matching manner; among them, rotating auxiliary convex strips 704 are fixedly arranged at equal intervals on the outer side wall of the locking cap body 703, the docking thread groove 706 is arranged at the center position of one end of the locking cap body 703, and a limiting wrapping ring 705 is also fixedly arranged at the edge side position of one end of the locking cap body 703; among them, the limiting wrapping ring 705 and the connecting ring body 607 are set in the same number of groups, and the inner diameter of the limiting wrapping ring 705 is equal to the ring diameter of the connecting ring body 607.

[0025] In order to further improve the stability of the connection between the internal thread fastening ring 604 and the plug-in cylinder body 601, the present solution also designs a matching locking cap body 703 for locking. That is, after the connecting threaded column body 701 is inserted into the plug-in cylinder body 601 and one end of the movable insertion strip 803 is squeezed, it is necessary to continue to push down the connecting threaded column body 701 until the auxiliary handle 702 at one end of the connecting threaded column body 701 is in close contact with the limit retaining ring 603 at the end of the plug-in cylinder body 601. At the same time, the other end of the connecting threaded column body 701 extends to the outside of the bottom barrel opening of the plug-in cylinder body 601. When using the locking cap body 703 for connection and locking, the docking thread groove 706 in the locking cap body 703 is threadedly connected to the bottom end of the connecting threaded column body 701. A rotation assisting convex strip 704 is fixedly arranged on the outer side wall of the locking cap body 703, and its purpose is to facilitate the loosening and tightening of the locking cap body 703, so that the operation can be carried out without the need to rely on external auxiliary work, bringing convenience to the operation of the staff. During the process of tightening the locking cap body 703, the limit wrapping ring 705 at one end of the locking cap body 703 will limit and squeeze the connecting ring body 607 arranged at the end of the internal thread fastening ring 604. That is, after the locking cap body 703 is tightened, the arranged auxiliary spring 606 is in a compressed state, which has a corresponding locking assisting effect on both the internal thread fastening ring 604 and the locking cap body 703, further improving its connection and fixing effect.

[0026] In this solution, for the use of the extension table, in order to facilitate the placement and positioning of larger components so as to facilitate the vibration test work, for the test of smaller components, the placement and positioning can be satisfied by the provided placement table 3; the connection components provided in this solution are very convenient for their connection, installation and fixation and subsequent disassembly work on the basis of ensuring the firm connection between the placement table 3 and the loading disc body 403; that is, when the extension table needs to be removed, first loosen the locking cap body 703. After loosening the locking cap body 703 and removing it, then loosen and remove the internal thread fastening ring 604. After that, the positioning of the plug-in cylinder body 601 can be released. That is, the staff holds the auxiliary handle 702 at one end of the connection threaded column body 701 with their hand, and then pulls out the connection threaded column body 701 upward. When pulling out the connection threaded column body 701, the extrusion contact of the connection threaded column body 701 with the movable insert 803, that is, the extrusion of the fastening chuck 802 will also be released. The fastening chuck 802 and the movable insert 803 retract and reset under the elastic return of the connection spring 805. The fastening chuck 802 separates from the fastening slot 501 and retracts into the accommodation cavity 801, and the positioning of the plug-in cylinder body 601 can be quickly released. After that, the plug-in cylinder body 601 can be removed. That is, push it up from the bottom end of the plug-in cylinder body 601. A part of the top of the plug-in cylinder body 601 is exposed. Then hold the limit retaining ring 603 with your hand and pull out the plug-in cylinder body 601. The plug-in cylinder bodies 601 at other positions can be removed one by one according to the same operation above. The operation is convenient, and the connection and fixation between the extension table and the placement table 3 can be released.
