Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides an embodiment: a welding rotary screw, comprising a connecting pad 6 for support, a hexagonal clamping plate 7 is fixedly arranged at the center of the upper end surface of the connecting pad 6, and a threaded shaft 5 is fixedly arranged at the center of the lower end surface of the connecting pad 6,

[0024] A connecting rotating groove 1 is provided at the center of the upper end surface of the hexagonal clamping plate 7, and four groups of fixed clamping grooves 2 are equidistantly provided on the inner end surface of the connecting rotating groove 1, and four groups of welding grooves 4 are equidistantly provided on the inner end surface of the connecting rotating groove 1 near the fixed clamping grooves 2 and penetrate to the bottom of the hexagonal clamping plate 7;

[0025] The welding plate 8 is fixedly arranged at the bottom of the inner end surface of the welding groove 4, and a clamping groove for limiting is opened at the bottom of the inner end surface of the connecting rotating groove 1;

[0026] The protective device 3 is elastically rotatably connected to the inner end surface of the connecting rotating groove 1 through the connecting groove.

[0027] The protective device 3 includes a closed rotating plate 32, an inner concave handle 31 is arranged at the center of the upper end surface of the closed rotating plate 32, and four groups of alignment grooves 33 are equidistantly provided on the side end surface of the closed rotating plate 32, four groups of positioning clamping plates 34 are equidistantly arranged on the lower end surface of the closed rotating plate 32, and a spring guide shaft 36 is fixedly arranged at the center of the lower end surface of the closed rotating plate 32, and a limiting chassis 35 is fixedly installed at the center of the lower end surface of the spring guide shaft 36.

[0028] The closed rotating plate 32 is adapted to the limiting chassis 35 through the clamping groove and then rotatably clamped on the inner end surface of the connecting rotating groove 1, which can effectively improve the stability of the closed rotating plate 32 rotating inside the connecting rotating groove 1.

[0029] The shapes of the fixing slot 2 and the welding slot 4 are the same as the alignment slot 33 , which facilitates the subsequent rapid and stable positioning and limiting.

[0030] The positioning card plate 34 is fixedly connected with the fixed card slot 2, and the positioning card plate 34 is fixedly connected with the welding slot 4, which can effectively improve the stability of the subsequent sealing of the welding plate 8 inside the welding slot 4 by the positioning card plate 34 after welding.

[0031] The closed rotating plate 32 is elastically connected to the inside of the connecting rotating groove 1 through the spring guide shaft 36. The spring guide shaft 36 can provide sufficient elastic force for the closed rotating plate 32, so that the closed rotating plate 32 can be stably limited inside the connecting rotating groove 1, thereby improving the stability of subsequent locking.

[0032] Working principle: During use, if it is necessary to weld the screws to the upper part of the accessory to be connected, the user can insert the threaded shaft 5 into the pre-drilled threaded hole, and then limit it to the outside of the hexagonal clamping plate 7 through an external tool for rotation. At this time, the threaded shaft 5 can lock the accessory through the threaded hole. When the threaded shaft 5 and the threaded hole are rotated until the connecting pad 6 fits the upper part of the accessory to be fixed to the limit, the user can insert the welding tool into the welding groove 4, and then weld the welding plate 8 to the accessory to be fixed for secondary fixation. At the same time, after the welding is completed, the user can hold the concave handle 31, and then pull it upward and rotate it. At this time, the spring guide shaft 36 stretches elastically, and at the same time drives the limiting chassis 35 and the closed rotating plate 32 to rotate inside the connecting rotating groove 1 until the welding groove 4 is directly opposite to the positioning clamping plate 34. At this time, the user can loosen the concave handle 31, and the closed rotating plate 32 and the positioning clamping plate 34 complete the protective closure of the upper part of the welding groove 4 under the elastic reset of the spring guide shaft 36.
