A support column is fixedly arranged at the center position of the upper surface of the turntable, and one end of the support column away from the turntable is connected to the surface of the second ball bearing.
[0010] As a preferred technical solution of the utility model, the four side walls of the support block are fixedly provided with electric telescopic rods, and the free ends of the four electric telescopic rods are respectively fixedly connected to the four side walls of the slider.
[0011] As a preferred technical solution of the utility model, two limit rails are symmetrically arranged on the upper surface of the circular table, and two movable clamps are connected to the upper surface of the circular table in a sliding limit position between the two limit rails. A lead screw is threaded through the side walls of the two movable clamps, and steel jaws are fixedly arranged on the opposite surfaces of the two movable clamps.
[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0020] Example
[0021] Please refer to Figure 1-4 As shown, the utility model provides a benchwork fixture, a cavity is opened on the bottom wall of a bottom plate 1, two counterweights 5 are limitedly slidably connected in the cavity, one end of the two counterweights 5 is connected with a handle 6 for pulling the counterweights 5, and two eccentric wheels 7 for limiting and fixing the counterweights 5 are symmetrically arranged on the front and rear side walls of the bottom plate 1, and then a turbine 3 is rotatably arranged in the cavity of the bottom plate 1 and above the two counterweights 5, a vortex rod 4 is meshingly connected to the side wall of the turbine 3, one end of the vortex rod 4 passes through the side wall of the bottom plate 1 and is connected with an adjusting button for rotating the vortex rod 4, and then a turntable 2 is fixedly connected to the upper surface of the turbine 3 through a connecting block;
[0022] When in use, first rotate the eccentric wheel 7. Since the eccentric wheel 7 is rotatably connected to the side wall of the bottom plate 1 through a rotating column, and the rotating column is set at the eccentric position of the eccentric wheel 7, when the eccentric wheel 7 is rotated, the edge of the eccentric wheel 7 will gradually release the limit on the counterweight block 5. After the eccentric wheel 7 completely releases the limit on the counterweight block 5, the handle 6 is used to pull the counterweight block 5 out of the cavity of the bottom plate 1, thereby increasing the contact surface between the bottom plate 1 and the ground, thereby increasing the stability of the entire device, avoiding the device from shaking when processing the workpiece to be processed, affecting the processing effect of the workpiece to be processed;
[0023] As a further implementation of this embodiment, Figure 1-4 As shown, four electric lifting rods 8 are arranged on the upper surface of the turntable 2, and the four electric lifting rods 8 are distributed in a rectangular shape. The free ends of the four electric lifting rods 8 are connected to a first ball bearing 11, and a slider 10 is rotatably connected to the outer side of the first ball bearing 11. The top ends of the four sliders 10 are limitedly slidably connected to the bottom wall of the round table 15, and a support block 12 is fixedly connected at the center position of the bottom wall of the round table 15. The bottom wall of the support block 12 is rotatably connected to a second ball bearing 14, and a support column 13 is fixedly connected to the surface of the second ball bearing 14. The support column 13 One end is fixedly connected to the upper surface of the turntable 2, and at the same time, electric telescopic rods 9 are fixedly arranged on the four surfaces of the support block 12, and the free end of the electric telescopic rod 9 is fixedly connected to the side wall of the slider 10, and then two limit rails 16 are symmetrically arranged on the upper surface of the round table 15, and two movable clamps 17 are slidably connected between the two limit rails 16, and screws 18 are threadedly penetrated on the surfaces of the two movable clamps 17, and an adjusting knob for rotating the screw 18 is arranged at one end of the screw 18, and then steel jaws 19 are arranged on the opposite surfaces of the two movable clamps 17;
[0024] When in use, the workpiece to be processed is set between the two steel jaws 19, and then the lead screw 18 is rotated so that the two movable clamps 17 drive the two steel jaws 19 to clamp the workpiece to be processed. When adjusting the angle of the workpiece to be processed, the worm rod 4 can be rotated so that the turbine 3 drives the turntable 2 to rotate, thereby realizing the rotation of the steel jaws 19 set above the turntable 2. At the same time, the electric lifting rod 8 can be adjusted to tilt the round table 15. When one electric lifting rod 8 is raised, the height of the electric lifting rod 8 on the other side of the support column 13 symmetrical to it is lowered, and at the same time, the length of the corresponding electric telescopic rod 9 is adjusted to make the slider 10 slide at the lower end of the round table 15 in a direction away from the center of the round table 15, and the round table 15 rotates around the center of the second ball bearing 14 at the upper end of the support column 13. The electric lifting rod 8 and the electric telescopic rod 9 are coordinated and adjusted in multiple directions to make the rotation of the round table 15 more stable, thereby realizing the adjustment of the inclination angle of the workpiece to be processed.
[0025] Specific working principle:
[0026] When in use, first rotate the eccentric wheel 7 so that the eccentric wheel 7 completely releases the limit on the counterweight 5, and then pull the counterweight 5 out of the cavity of the bottom plate 1 by pulling the handle 6, thereby increasing the contact surface between the bottom plate 1 and the ground, thereby increasing the stability of the entire device, avoiding the device from shaking when processing the workpiece to be processed, affecting the processing effect of the workpiece to be processed, and then set the workpiece to be processed between the two steel jaws 19, and then rotate the lead screw 18 so that the two movable clamps 17 drive the two steel jaws 19 to clamp the workpiece to be processed. When adjusting the angle of the workpiece to be processed, the worm rod 4 can be rotated so that the turbine 3 drives the turntable 2 to rotate , thereby realizing the rotation of the steel jaws 19 arranged above the turntable 2, and at the same time, the electric lifting rod 8 can be adjusted to tilt the round table 15. When one electric lifting rod 8 is raised, the height of the electric lifting rod 8 on the other side of the support column 13 symmetrical to it is lowered, and at the same time, the length of the corresponding electric telescopic rod 9 is adjusted to make the slider 10 slide at the lower end of the round table 15 in the direction away from the center of the round table 15, and the round table 15 rotates around the center of the second ball bearing 14 at the upper end of the support column 13. Through the coordinated adjustment of the electric lifting rod 8 and the electric telescopic rod 9 in multiple directions, the rotation of the round table 15 is smoother, thereby realizing the adjustment of the inclination angle of the workpiece to be processed.
