[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.
[0023] Reference Figure 1-2A clamping device for welding electrical iron accessories includes a base 1 and a clamping mechanism mounted on the base 1 via a placement seat 2. The clamping mechanism includes an adjusting part 3, a locking pin 4, a stud 5, a nut 6, a limiting plate 7, a locking pin 8, a washer 9, and a limiting seat 10. The limiting seat 10 slides against the placement seat 2. The adjusting part 3 passes through the placement seat 2 and is fixedly connected to the limiting seat 10. The adjusting part 3 is locked to the placement seat 2 by the locking pin 4. The stud 5 is fixed to the limiting seat 10. The nut 6 consists of two nuts that rotate on the stud 5 and are used to limit the position of the limiting plate 7. The locking pin 8 also limits the position of the limiting plate 7 via the washer 9.
[0024] According to the size of the electric iron accessory, push the two limiting seats 10 closer together so that the electric iron accessory is clamped between the two limiting seats 10. At this time, rotate the locking pin 4 to move downward and apply pressure to the adjusting part 3 to limit the adjusting part 3. This also limits the limiting seat 10. Then adjust the position of the limiting plate 7 so that the end of the limiting plate 7 fits against the upper edge of the electric iron accessory. Then rotate the nut 6 on the stud 5 and the locking pin 8 to lock the limiting plate 7, thereby limiting the upper end of the electric iron accessory. (It should be noted that when the limiting plate 7 applies pressure to the electric iron accessory, it is in an inclined state, with the end in contact with the electric iron accessory being the highest position, so as to facilitate the subsequent loosening of the limitation of the limiting plate 7 and removal of the processed electric iron accessory.)
[0025] The vertical cross-section of the placement seat 2 is L-shaped; a limiting seat 10 is placed on the upper surface of the longer side of the placement seat 2 so that the limiting seat 10 can move, and a slot with a trapezoidal opening is opened on the limiting seat 10 so as to place and clamp electric iron accessories of different sizes.
[0026] A sliding groove is provided in the middle of the adjusting part 3, and the locking pin 4 passes through the sliding groove. In order to allow the limiting seat 10 to move and adjust the distance between the two limiting seats 10 and clamp the electric iron accessory, a sliding groove is provided in the middle of the adjusting part 3 so that the adjusting part 3 can move without being obstructed by the locking pin 4. After the adjustment is completed, the locking pin 4 is rotated to limit the adjusting part 3 to the placement seat 2.
[0027] The upper end of the locking pin 4 is provided with a pad, the diameter of which is larger than the width of the groove of the adjusting part 3; the lower end of the locking pin 4 is provided with a thread, and rotating the locking pin 4 can apply pressure to the adjusting part 3 through the pad at its upper end, thereby limiting the adjusting part 3 on the placement seat 2.
[0028] The limiting plate 7 has a T-shaped structure. A latch is provided at the end of the limiting plate 7 to restrict the electric iron accessory. Two waist holes are also provided on the limiting plate 7, and the stud 5 and the second locking pin 8 pass through one waist hole respectively. When moving the limiting seat 10, the limiting plate 7 is adjusted according to the position of the electric iron accessory in the trapezoidal groove of the limiting seat 10, so that the latch at the end of the limiting plate 7 abuts against the upper edge of the electric iron accessory. The limiting plate 7 is then restricted by rotating the nut 6 on the stud 5 and rotating the second locking pin 8, thereby achieving stable restriction of the electric iron accessory. A distance is set between the two placement seats 2 so that the welding position of the electric iron accessory can be placed between the two placement seats 2 for easy welding. External pads can be selected as needed to temporarily support the welding position of the electric iron accessory and then removed for welding.
[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
