[0018] 2. The coffee table with lifting and extending functions has an extension mechanism. When the staff pulls the handle outward to drive the extended table plate to move outward, after the extended table plate moves outward to the extreme position, the extended table plate can automatically clamp downward to the left and right sides of the top of the top plate under the action of the slide tube and the positioning slider. The staff only needs to lift the extended table plate upward, and the slide plate can automatically drive the extended table plate inward to complete the reset under the action of the reset spring, which reduces the difficulty of the staff in resetting the extended table plate and is convenient for the staff to use.
[0019] 3. The coffee table with lifting and extending functions has a positioning mechanism. The slide drives the card block to move inward by itself under the action of compression spring 1, so that the card block passes through slide tube 1 and is connected to the front and rear sides of the top plate. After the extended table plate is retracted or extended, the position of the extended table plate can be fixed, which increases the stability of the coffee table after the state conversion during use. At the same time, slide tube 2 drives the positioning card rod to move inward under the action of compression spring 2, so that the positioning card rod can be connected to the embedded seat or the pull rod to complete the positioning of the card block at different positions. While increasing the stability of the card block being connected to the top plate, the card block can also be fixed in slide tube 1, which is convenient for the staff to move the position of the extended table plate and to convert the state of the coffee table.
[0020] 4. The coffee table with lifting and extending functions is provided with a lifting mechanism. During the use of the coffee table, the staff only needs to start the progressive motor to drive the threaded shaft to move up and down on the inner circle of the threaded cylinder to complete the lifting and adjusting processing of the entire coffee table, so that the specific horizontal height of the top plate of the coffee table can be adjusted according to the needs of use, which increases the applicability of the coffee table when in use, and is simple to operate and convenient for the staff to use.

Embodiment 3
[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 On the basis of the first and second embodiments, it is further obtained that the lifting mechanism 3 includes a lifting component 31 and a driving component 32, the lifting component 31 is arranged below the bottom plate 4, and the driving component 32 is arranged in the bottom of the top plate 6.
[0033] The lifting assembly 31 includes a base 3101, which is arranged below the bottom plate 4. The four corners of the top of the base 3101 are fixedly connected with telescopic legs 3102.

The connecting rod 3204 is fixedly connected to the inner side of the telescopic leg 3102, and the connecting rod 3204 is slidably connected to the outer circle of the telescopic leg 3103.
[0034] Furthermore: during the use of the coffee table, the staff only needs to start the progressive motor 3201 to drive the threaded shaft 3202 to move up and down on the inner circle of the threaded cylinder 3203, thereby completing the overall lifting and lowering adjustment of the coffee table, so that the specific horizontal height of the top plate 6 can be adjusted according to the needs of use when the coffee table is in use, thereby increasing the applicability of the coffee table when in use, and the operation is simple and convenient for the staff to use.
[0035] In actual operation, when the device is used and the height of the coffee table needs to be adjusted, the staff only needs to start the progressive motor 3201. The progressive motor 3201 starts to drive the threaded shaft 3202 to rotate, and the threaded shaft 3202 rotates on the inner circle of the threaded cylinder 3203 to move up and down. The threaded cylinder 3203 moves upward to drive the bottom plate 4 and the top plate 6 upward, and the threaded cylinder 3203 moves downward to drive the bottom plate 4 and the top plate 6 downward until the top plate 6 moves to a suitable height and then turn off the progressive motor 3201. At this time, the threaded shaft 3202 can complete the positioning of the top plate 6 by self-locking the thread between the threaded cylinder 3203, and the horizontal height adjustment of the top plate 6 is completed at this time. When the coffee table needs to be extended, the staff first pushes the levers 2305 on the left and right sides to move outwards. The levers 2305 move outwards and drive the positioning rods 2303 to move outwards through the national moving slide bar 2304 and the slide tube 2301, so that the positioning rods 2303 are retracted into the extended table 1101. Then the staff pulls the pull rings 2204 on the front and back sides to move outwards. The pull rings 2204 move outwards and drive the embedded seat 2202 to move outwards through the protruding rod 2203. The embedded seat 2202 moves outwards and drives the card block 2103 to move outwards through the pull rod 2201 and the slide 2101. The card block 2103 moves outwards and retracts into the slide tube 1103. Then the staff The movement of the moving slide bar 2304 is released. At this time, the slide barrel 2301 drives the positioning clamping rod 2303 to move inward and be connected to the pull rod 2201 under the action of the compression spring 2302, until all the positioning clamping rods 2303 are connected to the pull rod 2201. Then the staff can pull the handle 1303 outward, and the handle 1303 moves outward to drive the extension table 1101 to move outward until the extension table 1101 moves outward to the red limit distance. At this time, the slide barrel 1103 and the positioning slider 1104 drive the extension table 1101 to move downward under the action of the slide groove, so that the top of the extension table 1101 is flush with the top of the top plate 6, and the extension of the coffee table is completed at this time; Finally, the staff pushes the lever 2305 outward one by one. At this time, the lever 2305 drives the positioning rod 2303 outward to release the connection with the pull rod 2201, so that the slide 2101 drives the block 2103 inward to be connected to the front and rear sides of the top plate 6 under the action of the compression spring 1 2104, and then releases the push of the lever 2305. At this time, the slide cylinder 2301 drives the positioning rod 2303 to move inward and be connected to the seat 2202 under the action of the compression spring 2302. At this time, the position of the extended table 1101 is fixed.
