[0048] By adopting the above technical scheme, it is convenient to limit the driving gear 8 and avoid the situation that the driving gear 8 is separated from the gear cylinder 9, so that the height adjustment screw 3 can be limited to avoid the situation that the height adjustment screw 3 is separated from the screw cylinder 4. , reducing unnecessary troubles.
[0049] The working principle and application process of the present invention: when using the present invention, firstly, the switch of the height drive motor 7 can be activated, and under the meshing action, the driving gear 8 can drive the four gear cylinders 9 to rotate, so that the screw cylinder 4 can rotate along the height The adjustment screw 3 rotates, and under the meshing action, the four height adjustment screws 3 drive the support platform 1 to move longitudinally. During this process, the base 10 plays an effective supporting role. Carry out longitudinal movement along the gear cylinder 9 (the limit ring 5 plays an effective limit effect), until the support table 1 is adjusted to a height suitable for the operator to operate, and the switch of the height drive motor 7 is turned off;
[0050] The operator then places the electric drive axle between the two L-shaped clamping plates 11, starts the switch of the clamping drive motor 2, and under the meshing action, the driving bevel gear 20 drives the driven bevel gear 21 to rotate, thereby Make the clamping adjustment screw 13 rotate inside the support screw 15, and under the meshing action, the two support screws 15 drive the L-shaped clamping plate 11 to move toward each other along the limit chute 14, and then the L-shaped protective gasket 22 Under the action of clamping the electric drive axle, it also plays an effective role in protecting the electric drive axle;
[0051] When performing the test operation, if it is necessary to test different positions of the electric drive axle, it is only necessary to start the switch of the mobile drive motor 6 to make the mobile adjustment screw 19 rotate inside the mobile screw block 16. The block 16 moves along the inside of the moving groove 18, and then the mounting plate 12 drives the electric drive bridge above it to move, and moves to the designated position, and then closes the switch of the mobile driving motor 6;
[0052] During the movement of the mounting plate 12, the supporting slider 17 moves along the inside of the balance chute 25, which effectively balances the mounting plate 12, and when the supporting slider 17 moves, the anti-wear beads 28 roll along the concave frame 27 At the same time, sliding along the inside of the limit rail 26 effectively reduces the wear between the support slider 17 and the inner wall of the balance chute 25;
[0053] After the device has been used for a period of time, if the L-shaped protective gasket 22 is aging, the lower end of the L-shaped protective gasket 22 can be pulled under the action of an external force, and under the elastic force of the elastic clip 29, the elastic clip 29 is disengaged. slot 30, and then pull up the T-shaped guide block 24, so that the T-shaped guide block 24 moves along the T-shaped guide slot 23 until the T-shaped guide block 24 is completely separated from the T-shaped guide slot 23, that is, the L-shaped protective gasket 22 is completely removed. Next, the new L-shaped protective gasket 22 is reinstalled.
[0054] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
