[0046] In actual application, the width of the top surface 41 of the annular step 4 is only 2.5 mm, the outer diameter of the lock head 13 is slightly smaller than the inner diameter of the annular step 4, that is, the lock head 13 only needs to be offset by 2.5 mm to make the lock head 13 be dislocated with the annular step 4 and lock the expansion seat 2; and in the utility model, the rotation angle of the guide plate 8 from the unlocking position 72 to the locking position 71 is as high as 30 degrees, the arc-shaped guide hole 11 in the guide plate 8, the guide waist hole 6 of the base 1 and the structure and connection relationship of the moving shaft 12 are designed, so that small displacement offset of the lock head can be realized in the case that the guide plate 8 has a large rotation angle, the structure is compact and disassembly and assembly are convenient.

[0047] Before work, the device one (such as a first-aid device) and the device two (such as a stretcher on an ambulance or a rotating trolley) which need to be combined or separated are fixedly installed, wherein the device one needs to be taken off or installed on the device two, the base 1 of the connecting seat of the utility model is fixedly installed on the device two, and the expansion seat 2 of the utility model is fixedly installed on the bottom of the device one.

[0048] When the device one needs to be installed on the device two, first, the toggle switch 10 is toggled to the unlocking position 72, when the toggle switch 10 is toggled to the unlocking position, the toggle switch 10 drives the moving shaft 12 and the lock head 13 to move inward along the guide waist hole 6 relative to the base 1 and the expansion seat 2 through the guide arc-shaped hole 11 of the guide plate 8, so that the lock head 13 is moved to the inside of the positioning boss 5 as a whole, so that the position of the lock head 13 does not hinder the insertion hole 3 and the annular step 4 of the expansion seat 2 from being sleeved; then, the device one is aligned with the positioning boss 5 and the lock head 13 on the base 1 on the top of the device two through the bottom insertion hole 3 of the expansion seat and is sleeved downward, until the device one is placed on the base 1 on the top of the device two as a whole through the expansion seat 2; then, the toggle switch 10 is toggled from the unlocking position 72 to the locking position 71, when the toggle switch 10 is toggled to the locking position 71, the toggle switch 10 drives the moving shaft 12 and the lock head 13 to move outward along the guide waist hole 6 relative to the base 1 and the expansion seat 2 through the guide arc-shaped hole 11 of the guide plate 8, to be out of position with the top surface 41 of the annular step 4, at this time, the bottom surface 131 of the lock head 13 is just moved to the top of the top surface 41 of the annular step 4, the expansion seat 2 is locked and connected to the base 1 through the limitation of the lock head 13 to the annular step 4, and at this time, the expansion seat 2 can still rotate freely relative to the base 1 around the positioning boss 5 through the cooperation of the annular step 4 and the positioning boss 5, so that the device one is installed on the device two and the device one can still rotate relative to the device two.

[0049] When the device one needs to be separated from the device two, the toggle switch 10 is only toggled from the locking position to the unlocking position 72 again, so that the toggle switch 10 drives the moving shaft 12 and the lock head 13 to move inward relative to the base 1 and the expansion seat 2 along the guide waist hole 6 through the guide arc-shaped hole 11 of the guide plate 8, to be reset so that the lock head 13 is moved to the inside of the positioning boss 5 as a whole, so that the position of the lock head 13 does not hinder the expansion seat 2 from being pulled out of the base 1, then the device one and the expansion seat 2 are pulled out of the base 1, so that the device one is separated from the device two.

[0050] The utility model has the advantages of simple structure, good sealing, high stability, convenient and fast locking and connection of the expansion seat to the base, or separation of the expansion seat from the base, convenient operation, free rotation of the expansion seat relative to the base when the expansion seat is locked and connected to the base, and convenient use.

[0051] The above description is only a preferred embodiment of the utility model, and does not limit the utility model in any other form, and any modification or equivalent change made according to the technical essence of the utility model still belongs to the scope of protection of the utility model.
