[0002] Table is a common piece of furniture, people can eat, drink tea, study and work on the table, etc. Generally, the height of common tables is fixed, and the fixed height table is not suitable for people of different body shapes or people with different needs.

[0003] In response to the above problems, the Chinese utility model patent with patent number CN202410059311.9 (publication number CN117652781A) discloses "An Electric Liftable Desk", which includes a base and two parallel uprights vertically arranged on the base, a lifting rod arranged in the uprights, a sleeve arranged between the two lifting rods, a driver arranged at one end of the sleeve, a hexagonal connecting rod arranged in the sleeve, and a desk body arranged at the top of the two lifting rods. The desk body includes a table top, a drawer arranged at the bottom of the table top, a battery storage cabinet arranged at the bottom of the table top and adjacent to the drawer, a switch arranged at one end of the battery storage cabinet, an aviation plug arranged at the other end of the battery storage cabinet, and an operating button arranged at the bottom of the battery storage cabinet below the switch.

[0004] The lifting rod is inserted into the vertical rod. Since the lifting rod needs to move up and down relative to the vertical rod, there must be a gap between the lifting rod and the vertical rod to facilitate the movement of the lifting rod. At the same time, due to the manufacturing deviation of the lifting rod and the vertical rod, there will also be a gap between the lifting rod and the vertical rod. The existence of this gap will cause the lifting rod and the vertical rod to shake easily, which will make the table unstable. Utility Model Content

[0008] The flexible structure can be a flexible material made of rubber, silicone or the like, or it can be: the fastener is annular and sleeved on the rod body, the peripheral wall of the fastener is provided with a groove with an open top or bottom, the side wall of the fastener forming the groove is the flexible structure, the extrusion piece is inserted into the groove from the opening of the groove, and the extrusion piece can extrude the side wall corresponding to the groove, so that the side wall is inclined in a direction away from the center of the groove to conflict with the peripheral wall of the rod body. The structure of the fastener is simple.

[0009] Preferably, the extrusion piece is in the form of a sheet, the wall thickness of the extrusion piece gradually becomes thinner along the direction in which it is inserted into the groove, and the depth of the extrusion piece inserted into the groove can be adjusted. In this way, as the depth of the extrusion piece inserted into the groove increases, the degree of extrusion on the side wall of the groove increases; the depth of the extrusion piece inserted into the groove can be adjusted according to the size of the gap between the two rods, otherwise the interference between the side wall corresponding to the groove and the rod body is too large, which will affect the axial movement of the rod body and generate noise during the movement of the rod body; if the interference is small, it will cause shaking between the two rod bodies; the utility model is provided with an extrusion piece, which can make the fastener have good versatility and can be applied to different table legs.

[0010] In order to position the extrusion when it is inserted into the groove to a suitable depth and ensure that the deformation of the fastener is constant, a positioning piece is detachably mounted on the fastener. When the extrusion is inserted into the groove, the positioning piece is detachably connected to the fastener and the extrusion. In this way, the extrusion is positioned by the positioning piece; if the insertion depth of the extrusion needs to be adjusted, the positioning piece can be removed, and the extrusion can be adjusted to the right position before the positioning piece is installed.

[0011] In order to realize that the positioning member can be detachably connected to the fastener and the extrusion member, the positioning member is a bolt, the screw rod of the bolt passes through the notch of the groove, the extrusion member and the fastener threaded connection in sequence, and the head of the bolt abuts against the extrusion member.

[0012] Preferably, there are at least two flexible structures, which are sequentially spaced and arranged along the circumference of the fastener, so that the fastener and the rod body contact at multiple points, thereby improving the stability between the two rod bodies.

[0013] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a table, characterized in that it includes a table top and the above-mentioned table legs, wherein the top of one of the rods is connected to the table top, and the bottom of the other rod is used to support on a supporting surface.

[0014] Preferably, there are two fasteners to improve the relative stability of the two rods;

[0015] Two fasteners may be fixedly installed on the same rod at the same time, but when relative displacement occurs between the two rods, noise will occur. Therefore, preferably, the two fasteners are respectively fixed to one rod via a connecting structure.

[0016] The connection structure can have a variety of structural forms, and the structure is simple. The connection structure includes a protrusion and a slot in which the protrusion can be locked. The fastener is provided with a protrusion and a corresponding slot on the rod body; or the fastener is provided with a slot and a corresponding protrusion is provided on the rod body.

One fastener is relatively fixed to the lower part of the lifting rod, and the other fastener is relatively fixed to the upper part of the fixed rod. When the lifting rod is raised or lowered, the two fasteners are always located between the lifting rod and the fixed rod to ensure the relative stability between the lifting rod and the fixed rod.

[0018] Compared with the prior art, the utility model has the following advantages: the utility model arranges a fastener between the two rod bodies, and the fastener has a flexible structure that can be deformed laterally. When the gap between the two rod bodies is large, the flexible structure can be squeezed by the extrusion piece, so that the flexible structure is deformed and conflicts with the two rod bodies, thereby compensating for the gap between the two rod bodies, avoiding shaking between the two rod bodies, and ensuring good relative stability between the two rod bodies.

[0030] In this embodiment, the fastener 3 is annular and is sleeved on the rod body. A groove 32 with an open top or bottom is provided on the peripheral wall of the fastener 3. The side wall of the fastener 3 that forms the groove 32 is a flexible structure 31. The extrusion member 4 is inserted into the groove 32 from the open end of the groove 32, and the extrusion member 4 can extrude the side wall corresponding to the groove 32, so that the side wall is inclined in a direction away from the center of the groove 32 to contact the peripheral wall of the rod body.

When the lifting rod 1 is raised or lowered, the two fasteners 3 are always located between the lifting rod 1 and the fixed rod 2, ensuring the relative stability between the lifting rod 1 and the fixed rod 2.

[0036] The connection structure includes a protrusion 61 and a slot 62 in which the protrusion 61 can be locked. In this embodiment, the fastener 3 is provided with a protrusion 61 and the corresponding rod body is provided with a slot 62.
