[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4A balance for facilitating adjustment of the horizontality of a base comprises a balance body 1, a base 2 being provided at the bottom of the balance body 1, a plurality of adjustment slots 3 being symmetrically opened on the outer side of the base 2 in a rectangular shape, an adjustment pin 6 being installed in each adjustment slot 3 through a worm 5 for limiting rotation, and the other end of the worm 5 extending into the interior of the base 2 and connected to a worm gear 11 through tooth-groove meshing transmission, the middle portion of the worm gear 11 being connected to a rotating rod 10, the bottom of the rotating rod 10 being connected to a support column 4 through a threaded rod 12, and the support column 4 being installed at the bottom of the base 2;

[0023] Furthermore, a threaded barrel 7 is installed in the middle of the upper end of the support column 4, and the threaded barrel 7 is screwed to the threaded rod 12, and a rotation groove 44 is opened at the bottom of the support column 4. A support pad 41 is installed on one side of the rotation groove 44 through a ball head 42, and the support pad 41 is realized through the ball head 42 to achieve a certain rotation function, thereby adapting to the adjusted placement surface.

[0024] Furthermore, a plurality of bubble levels 8 are provided on the outer side of the base 2 .

[0025] Furthermore, the interior of the base 2 is symmetrically provided with a plurality of installation grooves 9 in a rectangular shape, and a rotating rod 10 is vertically installed inside the installation groove 9. The top end of the rotating rod 10 is rotatably installed on the top wall inside the installation groove 9, and a threaded rod 12 is provided at the bottom of the rotating rod 10.

[0026] Furthermore, a support column 4 is installed at the bottom of the installation groove 9.

[0027] Furthermore, one side of the worm 5 is set as a smooth rod section, which extends out of the adjustment slot 3 and is connected to the adjustment needle 6, and the other side of the worm 5 is provided with a spiral tooth groove and is rotatably installed on the inner wall of the mounting slot 9, wherein a damping rubber ring 13 is provided at the rotating connection between the worm 5 and the base 2.

[0028] Furthermore, a worm gear 11 is fixedly mounted on the middle portion of the rotating rod 10 , and one end of the worm gear 11 is connected to the worm 5 via tooth-groove meshing transmission.

[0029] Furthermore, a damping rubber pad 43 is provided on the inner wall of the rotating groove 44 , and the damping rubber pad 43 is in frictional and extrusion contact with the ball head 42 .

[0030] In this embodiment, the adjusting needle 6 at the corresponding position is adjusted to drive the worm 5 to rotate, and the worm 5 rotates and rotates through its spiral tooth groove engagement transmission worm wheel 11, and the worm wheel 11 is connected to the rotating rod 10. A threaded rod 12 is provided at the bottom of the rotating rod 10.
