The working process and principle of the invention are as follows:

the protection mechanism 3 is placed on the electrolytic bath 1 to be operated, the middle part of the protection mechanism 3 corresponds to the position of the copper bar 2 to be polished, then an operator enters the device from one side of the short side of the device and operates under the protection of the protection rods 13 on the left side and the right side, the balance of the operator is improved, after one-bath operation is finished, the operator leaves the device and simultaneously pushes the device from two ends by using the universal wheels 11 to transfer to the next bath surface to be operated, in the transferring process, when the guide wheel 174 on the fixing frame 173 is close to the electrolytic bath 1, the guide wheel 174 rotates to avoid the friction caused by the contact with the electrolytic bath 1 in the process of moving the protection mechanism 3, the protection effect is achieved, in the moving operation is repeated, and through the mutual matching of the protection rods 13 and the supporting round rods 15, various dangers caused by the bath falling of the operator in the operation process can be completely avoided, meanwhile, the operation efficiency of operators is enhanced, the operation speed is increased, the potential safety hazard is solved, and meanwhile, when the work is finished, the protection mechanism 3 is moved out of the electrolytic bath 1, the protection mechanism 3 is disassembled, the second downward-pressing buckle 16 pulls the limit plate 141, when the limit plate 141 is pulled, the pin 142 of the retainer plate 141 drives the first catch 144 to be pulled out from the second catch 16, and at the same time, the extension spring 143 is elastically deformed, then, the supporting round rod 15 is pulled upwards to take the second buckle 16 out of the splicing rod 8, the cylindrical rod 12 and the bearing rods 4 are disassembled in the same operation, the splicing rods 8 connecting the two bearing rods 4 are disassembled in the same manner, and the equipment with large floor area is disassembled into small parts to be placed, so that the effect of reducing the floor area of the equipment is achieved, the problem of large floor area of the equipment is solved, and meanwhile, the protection mechanism 3 is convenient to disassemble and assemble quickly;

in addition, when the equipment is assembled, the height of the protection mechanism 3 is adjusted according to the height of the electrolytic cell 1 so as to meet the operation requirements of adapting to different heights of the electrolytic cell 1, the lower end of the bearing rod 4 is inserted into the matched hollow tube 92, the adjusted height is controlled by observing the scale bars on the surface of the bearing rod 4 so as to ensure that the adjusted heights of the four bearing rods 4 are the same, the stability of the protection mechanism 3 is improved, after the height of the bearing rod 4 is adjusted, the adjusting rotary tube 91 is rotated, the adjusting rotary tube 91 drives the convex plate 93 on the inner wall to rotate, the convex plate 93 extrudes the positioning bayonet lock 94 during the rotation process, the positioning bayonet lock 94 is enabled to move towards the inside of the matched hollow tube 92, meanwhile, the reset spring 95 is enabled to generate elastic deformation, the positioning bayonet lock 94 drives the positioning clamping plates 96 on the two sides of the bearing rod 4 to carry out limiting clamping on the bearing rod 4, so reach the effect of fixing a position and the effect of reasonable height-adjusting to bearing bar 4, solve the problem that the equipment application range that exists is little through height-adjusting.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the following claims.
