[0025] Fixing mechanism, the fixing mechanism is arranged on the second mounting plate 4, the fixing mechanism includes two first rotating rods 5 and two rotating plates 6, two first mounting grooves 7 are opened on the lower surface of the upper cross plate of the second mounting plate 4, and the two first rotating rods 5 are respectively rotatably installed on the inner walls of the two first mounting grooves 7, and the two rotating plates 6 are respectively fixedly installed on the two first rotating rods 5.

[0026] Further, by starting the motor 12, the two rotating plates 6 move downward on the fixed plate 16 to fix multiple thermal protectors. Fixing multiple thermal protectors at one time improves the welding efficiency of the thermal protectors, thereby improving the work efficiency of workers.

[0027] Further, the fixing mechanism further includes a second rotating rod 8, two first gears 9 and two second gears 10. Second mounting grooves 11 are opened on the rear inner walls of the two first mounting grooves 7. The second rotating rod 8 is rotatably installed on the inner wall of the second mounting groove 11. The two first gears 9 are respectively fixedly installed on the second rotating rod 8, the two second gears 10 are respectively fixedly installed on the two first rotating rods 5, and the two first gears 9 are respectively meshed with the two second gears 10.

[0028] Further, a motor 12 is fixedly installed on the left surface of the second mounting plate 4. The output end of the motor 12 rotatably extends into the second mounting plate 4, and the motor 12 is fixedly connected to the second rotating rod 8.

[0029] Further, three circular grooves 13 are formed on the lower surface of the upper cross plate of the second mounting plate 4. Springs 14 are fixedly installed on the inner walls of the upper parts of the two circular grooves 13 at the left and right ends, and a sliding rod 15 is slidably installed on the inner wall of the circular groove 13 in the middle.

[0030] Further, a fixing plate 16 is fixedly installed at the lower ends of the sliding rod 15 and the two springs 14, and the fixing plate 16 is slidably connected to the inner wall of the second mounting plate 4.

[0031] Further, a placing plate 17 is slidably installed on the lower cross plate of the second mounting plate 4. Two limiting plates 18 are formed on the lower surface of the placing plate 17, and two limiting grooves 19 are fixedly installed on the lower cross plate of the second mounting plate 4 at positions corresponding to the two limiting plates 18.

[0032] Further, by placing a plurality of thermal protectors on the placing plate 17 and replacing the plurality of thermal protectors at one time through the placing plate 17, the replacement frequency of the thermal protectors by workers is reduced, thereby improving the welding efficiency of the thermal protectors by workers and improving the production efficiency of the thermal protectors.

[0033] Working principle: When using this device, multiple thermal protectors that need to be welded with leads are placed in the placement grooves on the placement plate 17. After placement, the placement plate 17 is lifted by the handles at both left and right ends of the placement plate 17, so that the limiting plate 18 under the placement plate 17 is aligned with the limiting groove 19, and then the placement plate 17 is placed on the second mounting plate 4. After placement, the hydraulic telescopic rod 3 is started, and the hydraulic telescopic rod 3 drives the second mounting plate 4 to move forward, so that the thermal protector moves forward, facilitating the welding by the worker. The motor 12 is started, the output end of the motor 12 rotates, driving the second mounting groove 11 fixedly connected to the output end of the motor 12 to rotate. Two first gears 9 fixedly connected to the outer surface of the second mounting groove 11 start to rotate, thereby driving two second gears 10 respectively meshed with the two first gears 9 to rotate. The two second gears 10 drive the corresponding two first rotating rods 5 to rotate. Two rotating plates 6 fixedly installed on the two first rotating rods 5 start to rotate. The front ends of the two rotating plates 6 rotate downward and leave the inside of the corresponding first mounting groove 7. The fixing plate 16 on the lower surface of the cross plate on the second mounting plate 4 presses downward. When the fixing plate 16 moves downward, it drives the sliding rod 15 fixedly connected to the upper surface of the fixing plate 16 to move downward in the corresponding circular groove 13. Two springs 14 fixedly connected to the upper surface of the fixing plate 16 are stretched. The fixing plate 16 fixes the multiple thermal protectors placed on the placement plate 17. At this time, the leads can be welded to the multiple thermal protectors. After welding is completed, the motor 12 is started, and the motor 12 rotates in the reverse direction, so that the two rotating plates 6 enter the inside of the two first mounting grooves 7 again and no longer press the fixing plate 16. The two springs 14 drive the fixing plate 16 upward, so that the fixing plate 16 returns to the upper position again. Then, the placement plate 17 is removed, and the welded thermal protectors are taken off, and the thermal protectors that need to be welded with leads are replaced and welded again. There is no need to weld one by one and then replace, reducing the labor intensity of the worker.
