[0043] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings and examples. Example 1

[0044] As shown in Fig. Figure 1 As shown in Fig. The lamp cap 110 includes an end cover 111, a shaft column 112, a first channel 113 and a second channel 114. The end cover 111 can be a circular plate structure, and the shaft column 112 can be a cylindrical column structure. The shaft column 112 is connected perpendicularly to one side of the end cover 111, and the connection method can be various, including but not limited to integral molding or separate fixing by threads, buckles, etc. The first channel 113 is arranged in the shaft column 112 and extends towards the end cover 111. Preferably, the first channel 113 extends along the axial direction of the shaft column 112 to the connection between the end cover 111 and the shaft column 112. The main function of the first channel 113 is to accommodate the wick 200. In some cases, the first channel 113 can prevent the wick 200 from being skewed. The second channel 114 is formed by two openings on the shaft column 112 perpendicular to the direction of the first channel 113 and the part of the inner space of the first channel 113, and is used to accommodate the lamp wire 300.

[0045] As shown in Fig. Figure 2As shown, the lamp cap 110 design includes an end cap 111 and a post 112 perpendicular to the end cap 111. The post 112 has a first channel 113 for accommodating the lamp wick 200, and a second channel 114 at the connection between the post 112 and the end cap 111, through which the lamp wire 300 passes directly. During assembly, the lamp wire 300 is first connected to the end of the lamp wick 200, and then one end of the lamp wick 200 with the lamp wire 300 is inserted along the first channel 113 to the bottom of the end cap 111. At this point, the lamp wire 300 is inserted into the second channel 114, forming a "T"-shaped structure between the lamp wire 300 and the lamp wick 200. After the lamp wick 200 and lamp wire 300 are installed, the lamp cap 110 is directly inserted into the lamp holder 120 and snapped in place, thus completing the assembly of the lamp head 100 and the lamp wire 300. The entire process is simple to install and highly stable.

[0046] like Figure 2 As shown, to facilitate the engagement of the post 112 with the lamp holder 120, a locking protrusion 115 is provided on the outer periphery of the post 112 for engaging with the lamp holder 120. The locking protrusion 115 has an inclined surface 116 on the side facing away from the end cover 111. When the post 112 is engaged with the lamp holder 120, the locking protrusion 115, under force, causes the post 112 to taper, thus facilitating its smooth insertion into the lamp holder 120. Once the post 112 is inside the lamp holder 120, the locking protrusion 115 returns to its original shape under elastic force, allowing it to directly engage with the lamp holder 120, achieving a secure connection between the lamp head 100 and the lamp holder 120. Furthermore, the inclined surface 116 on the locking protrusion 115 has a guiding function, further aiding in the smooth entry of the locking protrusion 115 into the lamp holder 120.

[0047] like Figure 2 As shown, the end cap 111 has a circular protrusion 117 on the side opposite to the shaft post 112, and a hook 118 is fixed in the middle of the circular protrusion 117. The circular protrusion 117 increases the distance between the hook 118 and the end cap 111, making it easier for the hook 118 to be suspended on the rope. The direction of the rope opening of the hook 118 is perpendicular to the extension direction of the second channel 114. The direction of the rope opening of the hook 118 is set to be perpendicular to the extension direction of the second channel 114, so that when the hook 118 is suspended on the rope through the rope opening, there will be no interference between the hook 118 and the lamp wire 300. Example 2

[0048] like Figure 4As shown in Figure 5, an adjustment device 119 is provided on the shaft post 112 or the end cap 111. The adjustment device 119 changes the size of the first channel 113 or the second channel 114 to accommodate lamp wicks 200 or lamp wires 300 of different sizes. The adjustment device 119, located on the shaft post 112 or the end cap 111, can change the size of the first channel 113 or the second channel 114. Changing the size of the first channel 113 allows it to fit different sizes of lamp wicks 200, thus fixing the lamp wick 200. Changing the size of the second channel 114 allows it to fit lamp wires 300 of different thicknesses, ensuring the lamp wire 300 can be smoothly inserted into the second channel 114 without wobbling. Example 3

[0049] like Figure 4 As shown, the adjusting device 119 includes two arc-shaped thin plates 1191 fixed within the first channel 113, extending axially along the first channel 113. The concave surfaces of the two arc-shaped thin plates 1191 are arranged opposite each other to form a secondary channel 1192 coaxially arranged with the second channel 114. The edges of the two arc-shaped thin plates 1191 have a gap 1193, which faces the second channel 114. The size of the gap 1193 is adapted to the size of the lamp wire 300, allowing the lamp wire 300 to pass straight through the second channel 114 from the connection between the end cap 111 and the shaft post 112. The arc-shaped thin plates 1191 are embedded within the main channel, and the secondary channel 1192 formed between the two arc-shaped thin plates 1191 is used to insert the lamp wick 200. The secondary channel 1192 can further refine the dimensions of the first channel 113, thereby achieving adaptive fixing for lamp wicks 200 of different sizes. The gap 1193 between the two curved thin plates 1191 can also be adjusted according to the size of the lamp wire 300. The gap 1193 further changes the size of the second channel 114 so that the lamp wire 300 can be smoothly inserted into the second channel 114 without shaking. Example 4

[0050] like Figure 5 As shown, the adjusting device 119 includes multiple thin pillars 1194 fixed within the first channel 113. The multiple thin pillars 1194 can be arranged in parallel, forming a secondary channel 1192 between them to accommodate the lamp wick 200. The multiple thin pillars 1194 can be flexibly combined, and the secondary channel 1192 formed between them can further reduce the size of the first channel 113, thereby achieving adaptive fixing for lamp wicks 200 of different sizes. Example 5

[0051] like Figure 6As shown in Figure 7, in the lamp holder 100 provided in this application, the lamp base 120 includes a connecting seat 121 and a bushing 123. The connecting seat 121 can be made of plastic or metal and is annular. The connecting seat 121 is equipped with a snap-fit ​​surface 122 that mates with the snap-fit ​​protrusion 115, and the snap-fit ​​surface 122 is located at one end face of the connecting seat 121. The connecting seat 121 is designed to snap-fit ​​with the lamp cap 110. After the lamp wick 200 and the lamp wire 300 are embedded in the lamp cap 110, the lamp wick 200 and the lamp wire 300 can be quickly fixed by simply snapping the snap-fit ​​protrusion 115 of the lamp cap 110 into the snap-fit ​​surface 122 of the connecting seat 121. This design greatly improves the installation efficiency of the lamp wire 300 and the lamp wick 200.

[0052] like Figure 7 As shown in Figure 8, the connector 121 is provided with a third channel 125. The third channel 125 runs straight through the outer peripheral sidewall of the connector 121. Preferably, the third channel 125 includes two notches opened at the upper end of the connector 121, and the channel formed by the two notches running in a straight line through the connector 121 is the third channel 125. When the connector 121 is connected to the lamp cap 110, the third channel 125 coincides with the second channel 114, specifically, the third channel 125 and the second channel 114 are kept in a straight line. The third channel 125 runs through the outer peripheral sidewall of the connector 121, so that after the connector 121 and the lamp cap 110 are engaged, the third channel 125 can be interlocked with the second channel 114, thereby confining the lamp wire 300 within the second channel 114 and the third channel 125, ensuring the stability of the connection between the lamp wire 300 and the lamp holder 100.

[0053] like Figure 7 As shown, the connecting seat 121 has a fourth channel 126 along its axial direction, which extends through the body of the connecting seat 121 from the center of its end face. The fourth channel 126 is used to accommodate and connect the shaft post 112. The fourth channel 126 can be used to connect the shaft post 112 of the lamp cap 110, so that the shaft post 112 and the connecting seat 121 can be smoothly connected. The inner wall of the fourth channel 126 is provided with a protrusion 128, which is used to prevent the lamp cap 110 from rotating within the lamp holder 120. The protrusion 128 can act as a barrier to prevent the lamp cap 110 from rotating relative to the lamp holder 120, thereby preventing the lamp wire 300 from twisting and breaking.

[0054] like Figure 7As shown, the connecting seat 121 is provided with a guide surface 127 at the end surface away from the sleeve 123. The guide surface 127 can cooperate with the inclined surface of the clamping portion, and can guide the shaft column 112 to be inserted into the connecting seat 121, so that the connection is more smooth. The sleeve 123 is fixedly connected to the outer periphery of the connecting seat 121, and has a thread 124 or a buckle for connecting the bulb on one end. The sleeve 123 can be made of metal or plastic. After the sleeve 123 is fixedly connected to the connecting seat 121, the bulb can be directly installed on the sleeve 123 by rotating the thread 124, so that the fixing work of the whole lamp holder 100 and the lamp holder 120 is completed. Example 6

[0055] The application provides a lamp holder 100 included in a lamp string. A plurality of lamp holders 100 are connected in series on a lamp cord 300, and a plurality of lamp holders 100 are connected with lamp wicks 200 and bulbs.

[0056] The above description is illustrative only, and is not limiting. The embodiments shown in the drawings are only one of the embodiments of the application, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above description, and without departing from the spirit of the application, similar structural modes and embodiments can be designed without creativity, and all of them should belong to the protection scope of the application.
