[0039] A retractable scale 19 is provided on the top surface of the fixed workbench 4 and the panel 8 .

[0040] The panel 8 and the fixed workbench 4 are made of steel.

[0041] The working principle of the above technical scheme: the main frame 1 is a frame structure, including four columns and longitudinal bars respectively arranged between the two front columns and the two rear columns. The upper cross bar 2 is rotatably set on the top of the main frame 1, and arc grooves are symmetrically set on the longitudinal bars on the front and rear sides of the main frame 1. The two ends of the upper cross bar 2 are respectively rotatably set in the arc grooves. The position between the front and rear cross bars of the main frame 1 is suspended. When installing the photovoltaic coil, the upper cross bar 2 is inserted into the center hole of the photovoltaic coil 100, and then the upper cross bar 2 is placed in the arc groove. The suspended position between the front and rear cross bars of the main frame 1 is used to accommodate the photovoltaic coil 100. The lower cross bar 3 is fixedly set on the side of the two columns 15 on the right side of the main frame 1, and the upper cross bar 2 is set parallel to the lower cross bar 3. The fixed workbench 4 is fixedly set below the lower cross bar 3 and is fixedly connected to the side of the two columns 15. The telescopic workbench is movably connected to the main frame 1 through a movable bracket. The top surface of the telescopic workbench and the top surface of the fixed workbench 4 are in the same horizontal plane. Lockable universal wheels 5 are provided at the bottom of the main frame 1 and the telescopic workbench.

[0042] The telescopic workbench is arranged on one side of the main frame connected to the fixed workbench, and the telescopic workbench is arranged parallel to the fixed workbench.

[0043] The telescopic workbench includes a first movable workbench 6 and a second movable workbench 7. The first movable workbench 6 is connected to the column 15 and the second movable workbench 7 through movable brackets respectively. The movable brackets connecting the first workbench 6 and the column 15 and the movable brackets connecting the first workbench 6 and the second workbench 7 are respectively arranged on both sides of the legs 10 of the first workbench 6 to prevent interference between the movable brackets.

[0044] The first movable workbench 6 and the second movable workbench 7 both include a panel 8, cross beams 9 are symmetrically arranged on the bottom surface of the panel 8, and legs 10 are fixedly arranged in the middle position of the lower end surface of the cross beam 9. The bottom surface of the legs 10 is fixedly connected to the lockable universal wheels 5. In order to increase the stability of the legs 10, connecting rods can be arranged at the upper and lower parts between the two legs 10 of the first movable workbench 6 to increase the stability of the legs. The legs of the second movable workbench 7 can also be provided with connecting rods in the same way.

[0045] A retractable ruler 19 is set on the top surface of the fixed workbench 4 and the panel 8. The retractable ruler can be a tape measure. The outer shell of the tape measure is fixedly set on the column 15 or the fixed workbench 4. The tape of the tape measure is in contact with the top surface of the fixed workbench 4 and the panel 8.

The retractable ruler can be symmetrically set front and back on the top surface of the fixed workbench and the panel 8 to facilitate use during cutting.

[0046] Before cutting the photovoltaic coil, push the photovoltaic coil cutting trolley to a suitable position, lock the lockable universal wheel 5 at the lower end of the main frame 1, and fix the position of the main frame 1.

[0047] When cutting the photovoltaic coil, pull the photovoltaic coil out from under the lower cross bar 3, and then lay the photovoltaic coil on the top surface of the fixed workbench and the telescopic workbench along the direction of the fixed workbench 4, the first movable workbench 6 and the second movable workbench 7, align the edge of the photovoltaic coil with the right edge of the second movable workbench 7, that is, align with the zero scale of the telescopic scale, and then adjust the position of the second movable workbench and the first movable workbench. Since the lower ends of the first connecting rod 11 and the second connecting rod 12 of the movable bracket are rotatably connected to the slider 18, the slider 18 can slide in the first slide groove 14 and the second slide groove 17. When pushing and pulling the second movable workbench 7 and the first movable workbench 6, the middle hinged position of the first connecting rod 11 and the second connecting rod 12 rotates with each other, so that the distance between the first movable workbench and the fixed workbench can be adjusted, and the distance between the second movable workbench and the first movable workbench can also be adjusted. After adjusting the positions of the first movable workbench and the second movable workbench, the universal wheels at the lower ends of the legs 10 are locked to fix the positions of the first movable workbench and the second movable workbench, and then the photovoltaic coils of appropriate sizes are cut.

[0048] After the photovoltaic coil is cut, the lockable universal wheel is unlocked, the first movable workbench is pressed against the fixed workbench, and the second movable workbench is pressed against the first movable workbench. Then the photovoltaic coil cutting trolley is pushed to a position where it does not affect the work. In order to prevent the two from moving when the first movable workbench is pressed against the fixed workbench, a clamping structure can be set between the fixed workbench and the first movable workbench. When pushing the photovoltaic coil cutting trolley, the first movable workbench is clamped with the fixed workbench. When adjusting the position of the first movable workbench, the clamping mechanism is released. The clamping mechanism is a clamping structure suitable for clamping the fixed workbench 4 and the crossbeam 9 in the prior art. There are many clamping structures in the prior art, such as the clamping mechanism described in the CN113608302B patent, which will not be described here. The same clamping mechanism can also be used between the second movable workbench and the first movable workbench.

[0049] The panel 8 and the fixed workbench 4 are made of steel, and when cutting is performed, cutting can be performed directly on the panel or the fixed workbench.
