When the lifting table is lifted and adjusted, the motor 9 drives the transmission shaft 8 to rotate, the transmission shaft 8 drives the two lead screws 4 to synchronously rotate, the lead screws 4 act on the nuts 6 to drive the inner tube 2 to stretch out and draw back along the outer tube 3, and then the inner tube 2 drives the table plate 1 to rise or fall.

The bottom fixed mounting of table 1 has the installation axle 10 of vertical extension, the upper end of installation axle 10 passes through bolt fixed mounting in the bottom of table 1, install mounting panel 11 on the installation axle 10 rotation, the middle part of mounting panel 11 passes through three rotations of bearing and installs the lower extreme at installation axle 10, connecting pipe 7 is located the below of mounting panel 11, the front end of mounting panel 11 is equipped with the installation department 12 of buckling downwards, the lower extreme forward slope setting of installation department 12, the front side of installation department 12 has the hand controller 13 that is used for controlling the support frame flexible through bolt fixed mounting, the front side of hand controller 13 is equipped with the button that is used for controlling motor 9 pivoted.

Specifically, the hand controller 13 is connected with the motor 9 through a wire, and the motor 9 can be driven to rotate positively and negatively by controlling the hand controller 13, so that the height of the table plate 1 is adjusted. When a user sits on the front side of the lifting table, the user faces the control panel of the hand controller 13, and the user can easily control the hand controller 13 so as to lift and adjust the lifting table; or when the user sits at the rear side of the lifting table, the control panel of the hand controller 13 is positioned at one side deviating from the user, and the user can rotate the mounting plate 11 by one hundred eighty degrees around the mounting shaft 10, so that the control panel of the hand controller 13 can rotate to one side facing the user, and the user can easily control the hand controller 13 to lift and adjust the lifting table, so that the lifting table is more flexible to use.

The bottom of mounting panel 11 is through bolt fixed mounting having mounting box 14, mounting panel 11 seals the top of mounting box 14, the lower extreme of installation axle 10 extends to in the mounting box 14 and coaxial fixed mounting has circular positioning disk 15, the even interval of outer peripheral face of positioning disk 15 is equipped with a plurality of triangle-shaped constant head tanks 16, slide mounting fixture block 17 around the diameter of positioning disk 15 in the mounting box 14 that is located positioning disk 15 directly behind, the front end of fixture block 17 is the triangle-shaped that coincides with constant head tanks 16, be equipped with in the mounting box 14 and be used for promoting the front end card of fixture block 17 and go into the spring 18 in the constant head tanks 16. When the position of the hand controller 13 is adjusted by rotating the adjusting mounting plate 11, the mounting plate 11 drives the clamping block 17 to rotate around the positioning disc 15, when the mounting plate 11 drives one end of the clamping block 17 to rotate to be opposite to one of the positioning grooves 16, the spring 18 pushes the clamping block 17 to move to the side close to the positioning disc 15, so that one end of the clamping block 17, which is triangular, is clamped into the positioning groove 16, and the damping sense of the mounting plate 11 during rotation is increased.

Two slide bars 19 which are arranged in parallel are fixedly arranged on the inner wall of the mounting box 14 in a left-right opposite mode, the slide bars 19 are parallel to one diameter of the positioning disc 15, the slide bars 19 extend front and back, external threads are arranged at the rear ends of the slide bars 19 and are screwed on the rear side wall of the mounting box 14, a supporting plate 20 is welded at the rear ends of the clamping blocks 17, the supporting plate 20 is slidably arranged on the two slide bars 19, and a spring 18 is sleeved on the slide bars 19 between the rear side wall of the mounting box 14 and the supporting plate 20. The sliding rod 19 provides supporting and guiding functions for the clamping block 17, so that the moving stability of the clamping block 17 is improved.

The installation box 14 below the clamping block 17 is internally provided with a swinging plate 21, the swinging plate 21 and the sliding rod 19 are arranged in parallel, the inner side of the bottom wall of the installation box 14 is fixedly provided with a hinge seat 22 through bolts, the front end of the swinging plate 21 is rotatably arranged on the hinge seat 22 through a pin shaft 23 extending transversely, a torsion spring 24 for driving the swinging plate 21 to rotate upwards around the pin shaft 23 is sleeved on the pin shaft 23, one side of the swinging plate 21 is provided with a convex baffle 25, one end of the torsion spring 24 is supported at the bottom of the baffle 25, the other end of the torsion spring is supported on the hinge seat 22, the bottom of the clamping block 17 is welded with a convex plate 26, the top of the swinging plate 21 is provided with a limiting groove 27 for the convex plate 26 to be clamped in, when one end of the clamping block 17 is clamped in the limiting groove 16, the swinging plate 21 is rotated upwards around the pin shaft 23 so as to be clamped in the limiting groove 27, and one end of the clamping block 17 is prevented from being separated from the limiting groove 16 when clamped in the limiting groove 27 through the convex plate 26.

Specifically, when the adjustment mounting plate 11 is rotated to adjust the position of the hand controller 13, the rear end of the swinging plate 21 is pressed against the torsion of the torsion spring 24 to drive the swinging plate 21 to rotate downwards around the pin 23, so that the convex plate 26 is separated from the limiting groove 27, the limiting groove 27 does not limit the radial movement of the clamping block 17 and the convex plate 26 along the positioning disk 15, and when the mounting plate 11 is rotated by applying force, the clamping block 17 can smoothly move to the side far from the positioning disk 15 and separate from the positioning groove 16.

After the installation plate 11 is rotated and the hand controller 13 is rotated to a required position, the pressing of the swinging plate 21 is canceled, the torsion of the torsion spring 24 drives the swinging plate 21 to rotate upwards around the pin shaft 23, so that the convex plate 26 is clamped into the limiting groove 27, the limiting groove 27 plays a role in limiting the moving distance of the clamping block 17 and the convex plate 26 to the side far away from the positioning disc 15, when the convex plate 26 abuts against one end of the limiting groove 27 far away from the positioning disc 15, one triangular end of the clamping block 17 is insufficient to be separated from the positioning groove 16, the rotation of the installation plate 11 is limited, the position of the hand controller 13 is kept fixed, and the position of the hand controller 13 is prevented from being offset due to the fact that the installation plate 11 is touched by mistake.

In order to facilitate adjusting the swinging plate 21, a shifting handle 28 is integrally formed at one end of the swinging plate 21 far away from the pin shaft 23, a through hole for the shifting handle 28 to penetrate is formed in the rear side wall of the mounting box 14, and an anti-slip sleeve 29 is sleeved on the shifting handle 28.

The foregoing has shown and described the basic principles, main features and advantages of the present utility model.
