In recent years, with the development of the electronics industry, the power tool industry has also undergone significant changes. Its products now boast superior performance, energy efficiency, environmental friendliness, and safety, giving consumers greater peace of mind and thus gaining popularity. To cater to outdoor workers, many DC lithium-ion power tools have been developed. Currently, the lithium-ion chargers and light guides provided by existing companies use an interference fit between the housing and the light guide, requiring workers to hammer them in with rubber hammers. This assembly method is labor-intensive, material-intensive, and time-consuming. Furthermore, the mass production of housing and light guide molds leads to wear and tear on the parts, causing the original interference fit to become a loose fit. When picked up, the light guide falls off, requiring complete rework, increasing workload, costs, and efficiency. Utility Model Content

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1 As shown, a light guide column assembly structure for easy installation of a charger includes an upper housing 1 and a light guide column 2. The upper housing 1 has a first positioning structure 11 for limiting and fitting the light guide column 2 within its installation area. The light guide column 2 has at least one snap-fit ​​part 21, and the upper housing 1 has a corresponding second positioning structure 12 that cooperates with the snap-fit ​​part 21. The light guide column 2 is assembled onto the upper housing 1 by the snap-fit ​​part 21 and the second positioning structure 12, and is limited circumferentially and radially by the first positioning structure 11.

[0018] The first positioning structure 11 includes a first mating part 101, a second mating part 102, and a third mating part 103 disposed in the mounting area of ​​the upper housing 1; the first mating part 101, the second mating part 102, and the third mating part 103 are protruding positioning posts or recessed positioning grooves, used to fit against the corresponding outer or inner surface of the light guide post 2.

[0019] The latching part 21 includes a first latch 201 and a second latch 202 disposed on the light guide post 2. The second positioning structure 12 includes a fourth mating part 104 and a fifth mating part 105 disposed on the upper housing 1. The fourth mating part 104 and the fifth mating part 105 are slots or latches that mate with the first latch 201 and the second latch 202. The first latch 201 and the second latch 202 are elastic barbed structures or L-shaped hooks. The fourth mating part 104 and the fifth mating part 105 are slots in the form of through holes or blind holes penetrating the upper housing 1, and their inner sidewalls are provided with recesses or protrusions that engage with the latching part 21.

[0020] The light guide post 2 is made of a light-transmitting material, and its main body is a columnar structure with one end being a light-emitting surface and the other end being a light-incident surface. The latching part 21 is disposed on the side wall or end of the light guide post 2. The first positioning structure 11 and the second positioning structure 12 are spatially staggered, so that the light guide post 2 is initially positioned by the first positioning structure 11 during assembly, and then finally fixed by the latching part 21 and the second positioning structure 12.

[0021] During assembly, the operator only needs to align the light guide column 2 with the mounting area of ​​the upper housing 1.

[0022] First, align the bottom groove or plane of the light guide post 2 with the third mating part 103 of the upper housing 1 and put it down. At this time, the outer wall of the light guide post 2 simultaneously contacts the first mating part 101 and the second mating part 102, completing the initial radial and axial positioning. This process does not require force.

[0023] Then, a small positive pressure perpendicular to the mounting plane is applied to the light-emitting surface of the light guide post 2. Under the action of the pressure, the light guide post 2 moves downward as a whole, and the barbed bevels of the first latch 201 and the second latch 202 on its side wall begin to contact and squeeze with the upper edges of the fourth mating part 104 and the fifth mating part 105, forcing the two L-shaped cantilever latches to produce an inward (towards the center of the light guide post 2) elastic bending deformation.

[0024] As pressure continues to be applied, once the barb crosses the upper edge of the slot, the two latching parts 21 quickly spring back to their original position due to their own elasticity. The barb at the end will "click" and engage with the anti-retraction rib in the slot. At this time, the bottom of the light guide post 2 is completely fitted with the third mating part 103, and the side is in contact with the first mating part 101 and the second mating part 102. The latching part 21 is firmly locked to the slot, thus limiting the position of the light guide post 2 in five degrees of freedom (X, Y, Z axis movement and rotation around the X and Y axes). Only the rotational degree of freedom around the Z axis (optical axis) is retained, but this degree of freedom is restricted by the non-circular bottom or platform structure of the light guide post 2, thereby achieving completely reliable fixation.

[0025] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
