[0025] In a specific implementation manner, an electric push rod 19 is provided, and the plane of the workbench 2 can change its angle through the extension and retraction of the electric push rod 19. When the electric push rod 19 moves, the universal ball 15 is driven to move, so that one side of the second sealing block 16 contacts the extrusion rod 17, so that the extrusion rod 17 squeezes the second sealing block 16 and causes the second sealing block 16 to shrink inward, and drives the first sealing block 12 to seal the other end of the oil outlet groove 18 through the connecting rod 10, so as to avoid excessive outflow of lubricating oil in the oil storage tank 20 and cause waste. The lubricating liquid in the oil outlet groove 18 flows out through the second sealing block 16 being separated from the oil outlet groove 18, thereby lubricating the universal ball 15 to reduce wear and tear, thereby increasing the service life of the device.

[0026] Two through slots 3 are provided on the top of the workbench 2, and a bearing is embedded on one side of the inner wall of the through slot 3, and a rotating shaft is rotatably connected in the bearing, and a threaded rod 4 is connected to one end of the rotating shaft, and the other end of the threaded rod 4 extends out of the through slot 3 and is connected to a turntable 6, and a crank 7 is rotatably connected to one side of the turntable 6, a threaded seat 5 is threadedly connected to the outer wall of the threaded rod 4, and a splint 1 is connected to the top of the threaded seat 5, and the bottom of the splint 1 is in contact with the top of the workbench 2, a rubber pad is provided on the surface of the crank 7, and the surface of the rubber pad is provided with anti-slip convex patterns.

[0027] In a specific implementation manner, a crank 7 is provided and the crank 7 is shaken to rotate, so that the crank 7 drives the turntable 6 to rotate, and then the turntable 6 drives the threaded rod 4 to rotate, and the threaded rod 4 rotates to drive the threaded seat 5 to move, and then the threaded seat 5 drives the clamp 1 to move, so that the two clamps 1 clamp and fix the surface of the object to prevent the object from slipping during experimental operations, and by providing convex patterns on the surface of the clamp 1, the friction force on the surface of the clamp 1 is increased, so that the object can be better fixed.

[0028] Working principle: When in use, by turning the crank 7, the crank 7 drives the turntable 6 to rotate, and then the turntable 6 drives the threaded seat 5 to move through the threaded rod 4, so that the two clamping plates 1 move toward each other, so as to fix the objects, and then the electric push rod 19 is extended and retracted, so that the workbench 2 platform can change its angle. During the extension and retraction of the electric push rod 19, the universal ball 15 moves in the fixed sleeve 9, so that the second sealing block 16 contacts the extrusion rod 17, and then the second sealing block 16 shrinks inward, so that the lubricating fluid in the oil outlet groove 18 flows out, and then the surface of the universal ball 15 is lubricated, thereby reducing wear and increasing service life.
