[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 3 , Figure 4 As shown, the conventional E26 / 27 solderless lamp holder 3 includes a cup-shaped lamp holder housing 301 and an insulator 302 disposed at the bottom of the lamp holder housing 301. The insulator 302 is made of plastic, and a circular groove 303 is formed at the bottom of the insulator 302. A cylindrical protrusion 304 protrudes downward in the middle of the top wall of the groove 303. A wire-passing hole 305 is formed at the center of the protrusion 304 for the drive power guide wire 4 to pass through. The wire-passing hole 305 is connected to the inner cavity of the lamp holder housing 301. A rivet 307 for fixing the guide wire 4 is installed in the wire-passing hole 305. A guide wire mounting cavity 306 is formed between the outer side wall of the protrusion 304 and the inner side wall of the groove 303.

[0027] To prevent the guide wire 4 from being pulled into the wire-threading hole 305 when the rivet 307 is pressed into it, this embodiment proposes a lamp guide wire installation device, such as... Figure 5-7 As shown, it includes a handle 1 and a cylindrical body 2 disposed at one end of the handle 1. The cylindrical body 2 and the handle 1 can be integrally formed or separate. If it is separate, the cylindrical body 2 can be installed on the handle 1 by means of threaded connection.

[0028] Furthermore, the cylindrical body 2 has a hollow cylindrical structure and is adapted to the wire mounting cavity 306 of the solderless lamp holder 3. When the cylindrical body 2 is inserted into the wire mounting cavity 306, the wire 4 passing through the wire hole 305 of the solderless lamp holder 3 is bent into the wire mounting cavity 306, and at the same time, the wire 4 is bent into a U-shape in the wire mounting cavity 306.

[0029] When using, such as Figure 8 As shown, hold the handle 1 with your hand, align the cylindrical body 2 with the guide wire mounting cavity 306 of the solderless lamp holder 3, and then press down on the guide wire 4; as shownFigure 9 As shown, the guide wire 4 is pressed and bent twice on the solderless lamp holder 3 to form a double U-shaped structure, one U-shaped structure is located in the guide wire mounting cavity 306, and the two free ends thereof abut the inner side wall of the groove 303 and the outer side wall of the protruding part 304 respectively, and the other U-shaped structure wraps the side wall of the protruding part 304, and the two free ends thereof abut the inner side wall and the outer side wall of the protruding part 304 respectively; then, as shown, Figure 10 As shown, the excess part of the guide wire 4 is cut off by the diagonal cutting pliers, and it is necessary to note that the wire foot of the guide wire 4 should not be higher than the end face of the groove, so as to avoid the gap after the rivet 307 is installed; finally, the rivet 307 is pressed into the wire passing hole 305 to fix the guide wire 4.

[0030] The guide wire 4 is bent twice by the cylindrical body 2 to form a double U-shaped structure, and the guide wire 4 is double-restricted by the guide wire mounting cavity 306 and the protruding part 304, so that the guide wire 4 is hooked and will not be brought into the wire passing hole 305 when the rivet 307 is pressed into the wire passing hole 305, thereby avoiding the poor contact between the rivet 307 and the guide wire 4.

[0031] As preferred, as shown, Figure 7 The end face of the cylindrical body 2 is arc-shaped. By setting the end face of the cylindrical body 2 as arc-shaped, the contact area with the guide wire 4 is increased, so that the guide wire 4 will not be damaged when being bent.

[0032] As preferred, the thickness of the cylinder wall of the cylindrical body 2 is slightly smaller than the difference between the guide wire mounting cavity 306 and twice the diameter of the guide wire 4. By adopting the above design, the guide wire 4 is effectively abutted against the inner side wall of the groove 303 and the side wall of the protruding part 304 respectively after being bent, so that the guide wire 4 is further restricted and prevented from shaking.

[0033] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above embodiments. Any technical solutions falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principle of the present application shall also be considered as the protection scope of the present application.
