The bottom end of the vertical rods 4 is fixedly installed on the upper surface of the lower body 2. Multiple rectangular openings are circumferentially formed on the surface of the hollow rods 3. Locking blocks 5 with right-angled triangular cross-sections are slidably arranged in the rectangular openings. Multiple spring rods 6 are fixedly installed on the surface of the vertical rods 4. One end of each spring rod 6 is fixedly connected to the surface of the locking blocks 5. Mounting blocks 7 are fixedly installed on both the left and right ends of the upper body 1. Through holes 8 are formed on the surface of the mounting blocks 7. Two through holes 8 are respectively used for two vertical rods 4 to pass through. The distance between the lower surface of the locking block 5 and the upper surface of the lower body 2 is adapted to the thickness of the mounting block 7.
[0024] Multiple spring rods 6 fixedly installed on the surface of the vertical rod 4 retract together under the control of a pressing assembly. The pressing assembly includes multiple vertical plates 9 respectively fixedly sleeved on the multiple spring rods 6 and multiple inclined plates 10 respectively fixedly installed on the surface of the bottom end of the multiple spring rods 6. The surface of the lower seat 2 is provided with a concave opening 11. Abutment rings 12 are symmetrically and vertically slidably installed in the concave opening 11 through a sliding component. The sliding component includes two sliding rods 13 respectively fixedly installed on the surface of the two abutment rings 12. The opening wall of the concave opening 11 is symmetrically and vertically provided with sliding grooves 14. One end of the two sliding rods 13 is slidably arranged in the two sliding grooves 14 respectively. The top wall of the concave opening 11 is provided with multiple through openings 18 respectively connected to the inside of the two hollow rods 3. The bottom ends of the multiple vertical plates 9 pass through the multiple through openings 18 respectively. The two abutment rings 12 are in sliding contact with the multiple inclined plates 10 respectively.
[0025] When it is needed to install the upper seat body 1 and the lower seat body 2, first, the two through holes 8 opened on the surfaces of the two installation blocks 7 on the two sides of the upper seat body 1 are respectively corresponded to the positions of the two vertical rods 4, then the upper seat body 1 is controlled to move downwards, after the top ends of the two vertical rods 4 pass through the two through holes 8 respectively, with the moving downwards of the upper seat body 1, the mouth walls of the through holes 8 will slide in contact with the inclined surfaces of the plurality of clamping blocks 5, under the abutting of the inclined surfaces, the plurality of clamping blocks 5 will move close to each other, and the plurality of spring rods 6 will contract together, until the lower surfaces of the two installation blocks 7 are all in abutment with the upper surface of the lower seat body 2, at this time, the installation blocks 7 are located between the plurality of clamping blocks 5 and the lower seat body 2, and the installation blocks 7 no longer abut against the plurality of clamping blocks 5, the abutting force of the installation blocks 7 on the plurality of clamping blocks 5 disappears, and the plurality of clamping blocks 5 will quickly move back to the original positions under the elastic potential energy of the plurality of spring rods 6, at this time, the installation blocks 7 will cooperate with the gaps between the lower surfaces of the plurality of clamping blocks 5 and the upper surface of the lower seat body 2, so as to complete the locking between the upper seat body 1 and the lower seat body 2.
[0026] When it is needed to release the locking between the upper seat body 1 and the lower seat body 2, the two abutting rings 12 can be controlled to move upwards, so that the outer ring walls of the abutting rings 12 slide in contact with the inclined surfaces of the plurality of inclined plates 10, under the abutting, the plurality of clamping blocks 5 will move close to each other, and the plurality of spring rods 6 will also contract together, until the plurality of clamping blocks 5 move to the lower surfaces which no longer contact with the upper surfaces of the installation blocks 7, at this time, the upper seat body 1 and the lower seat body 2 can be separated, which is convenient and fast.
