The working principle is as follows:

firstly, when a user holds the grip 7 to support the bottom plate 2, the grip 7 can slide off the hand due to water in the hand of the user, so that the anti-slip sleeve 8 with uneven surface is arranged on the periphery of the grip 7, then the user can hold the grip 7 through the anti-slip sleeve 8, the anti-slip sleeve 8 can increase the friction force between the hand of the user and the grip 7, and the grip 7 is prevented from sliding due to water in the hand of the user when in use;

then, when the user does not hold the whole clamp 1, the handle 7 can drive the connecting rod 701 to be screwed out from the connecting hole I501 of the connecting plate 5 in the anticlockwise direction, then the whole clamp 1 can be directly rotated on a desktop for use, when the user needs to adjust the position of the handle 7, the handle 7 can be screwed out from the connecting hole I501 and then put into the connecting hole II 502 for screwing and fixing, and then the user can drive the whole clamp 1 to use through the handle 7, so that the arrangement of the connecting rod 701 is convenient for the user to install and detach the handle 7 according to actual conditions;

then, when the height of the support plate 3 is not consistent with the middle height of the milling workpiece, a user can press the button 6 on one side of the connecting plate 5 to start the control circuit board 10, so that the control circuit board 10 controls the four hydraulic telescopic rods 4, so that the hydraulic telescopic rods 4 push the support plate 3 upwards through corresponding piston rods, when the support plate 3 is pushed to the corresponding height, the button 6 on one side is released, so that the control circuit board 10 stops the hydraulic telescopic rods 4, so that the support plate 3 stops at the corresponding position, then the user can rotate the knob 901 of the fixing mechanism 9 to enable the fixing mechanisms 9 on two sides to attach and fix the surface of the milling workpiece under the rotation of the knob 901 and the threaded rod 902, the button 6 on the other side of the corresponding connecting plate 5 can move the support plate 3 downwards, so that the adjusting mechanism is convenient for the user to fix the milling workpieces with different heights, the condition that the milling workpiece is too high and cannot be fixed stably is avoided, so that the adjustability of the whole fixture 1 is greatly improved;

next, when the clamping plate 905 directly clamps the surface of the milling workpiece, the collision force on the surface of the milling workpiece is damaged, so that a rubber pad 906 with good resilience is arranged at the joint of the clamping plate 905 and the surface of the milling workpiece, and when the clamping plate 905 drives the rubber pad 906 to be jointed with the surface of the milling workpiece, the rubber pad 906 rebounds and offsets the collision force generated between the clamping plate 905 and the surface of the milling workpiece, so that the surface of the milling workpiece is not damaged by the larger collision force;

finally, when the clamping plate 905 is damaged, a user can rotate the bolt 908 out of the groove at the other side of the splicing cylinder 904 and the hole of the splicing column 903 in the anticlockwise direction by a corresponding screwdriver (a common cross screwdriver), and after the bolt 908 is taken out, the user can hold the clamping plate 905 to drive the splicing cylinder 904 to be taken out of the splicing column 903, so that a new clamping plate 905 can be lapped with the splicing column 903 through corresponding steps for use, wherein the splicing cylinder 904 and the clamping plate 905 are lapped through the limiting column 907, and the front cross section of the limiting column 907 is narrow at one side and wide at the other side, so that the clamping plate 905 cannot drive the limiting column 907 to be directly pulled out from the splicing cylinder 904, but the splicing cylinder 904 rotates along with the threaded rod 902 because the limiting column 907 is movably connected with the splicing cylinder 904, the clamping plate 905 and the limiting column 907 cannot rotate along with the splicing cylinder 904, so that the replacing mechanism is convenient for the user to separately take down and replace the clamping plate 905 and the splicing cylinder 904, the condition that the cost is wasted due to the fact that the clamp body 1 needs to be replaced when the clamping plate 905 is damaged is avoided, and therefore the dismounting performance of the clamp body 1 is greatly improved, and the clamp is the working principle of the clamp for milling the surface of a workpiece.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
