DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments.

[0026] As Figures 1-5As shown, this embodiment proposes a fixing device for drilling holes in a plastic shell, including a base 1. An adjusting plate 3 is fixedly installed on the top of the base 1. Multiple fixing mechanisms 5 are installed on the outer side of the adjusting plate 3 on the top of the base 1. Multiple elastic support mechanisms 4 for supporting the plastic shell are adjustablely installed on the adjusting plate 3. A positioning component that cooperates with the elastic support mechanism 4 is installed on the top of the base 1. The positioning component is located on the outer side of the adjusting plate 3. Through the arrangement of the adjusting plate 3, the elastic support mechanism 4, and the fixing mechanism 5, the elastic support mechanism 4 can support the suspended part of the inner wall of the plastic shell during use. Moreover, the position of the support mechanism can be flexibly adjusted in conjunction with the adjusting plate 3. At the same time, with the fixing mechanism 5 fixed on the outer side of the plastic shell, it can better provide stable support and fixation for the shell. Compared with the traditional support method of wooden blocks or plastic waste, this design can effectively avoid the problem of drilling deformation caused by unstable support. Through the setting of the elastic support mechanism 4, the elastic support mechanism 4 can adaptively support the top of the inner wall of the plastic shell under its own elastic force during use. There is no need to adjust the height during use, which can effectively improve the fixing speed and make it more flexible and convenient to use.

[0027] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the adjusting plate 3 is further provided with through holes 7 that cooperate with the elastic support mechanism 4. Multiple through holes 7 are provided and evenly distributed on the adjusting plate 3. It should be noted that the through holes 7 allow for flexible adjustment of the position of the elastic support mechanism 4, thereby facilitating the support of different parts of the plastic shell.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the elastic support mechanism 4 further includes an adjusting rod 401 movably connected to the adjusting plate 3 through a through hole 7. A first pad 402 is installed on the top of the adjusting rod 401, and a spring 403 located outside the adjusting rod 401 is connected to the bottom of the first pad 402. The bottom of the spring 403 abuts against the top of the adjusting plate 3. It should be noted that during use, the spring 403 can abut against the adjusting plate 3 to support the first pad 402. At the same time, the spring 403 will shorten when subjected to compressive force, which can effectively adapt to different heights of the plastic shell. The first pad 402 has a hollow structure, which can prevent the drill bit from getting stuck on the first pad 402.

[0029] like Figure 1 and Figure 2As shown, in a preferred embodiment, based on the above method, the fixing mechanism 5 further includes a first threaded rod 501 and a second threaded rod 502 symmetrically installed on the top of the base 1. The first threaded rod 501 and the second threaded rod 502 are jointly mounted with a fixing plate 503 that is slidably connected to them. A second pad 505 is provided at the bottom of the inner wall of the fixing plate 503. Adjusting nuts 504 for adjusting the position of the fixing plate 503 are installed on both the first threaded rod 501 and the second threaded rod 502. It should be noted that during use, the fixing plate 503, in conjunction with the adjusting nut 504, the first threaded rod 501, and the second threaded rod 502, can fix the plastic shell to the top of the adjusting plate 3. The second pad 505, placed between the plastic shell and the fixing plate 503, can protect the plastic shell.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the positioning component further includes a first limiting plate 2 installed on the top of the base 1 and a first adjustable limiting mechanism 6 and a second adjustable limiting mechanism 8 disposed opposite to each other. The first limiting plate 2 is located on one side of the adjusting plate 3. It should be noted that the arrangement of the first limiting plate 2, the first adjustable limiting mechanism 6 and the second adjustable limiting mechanism 8 facilitates the positioning of the plastic shell.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, both the first adjustable limiting mechanism 6 and the second adjustable limiting mechanism 8 include a mounting base 601 installed on the top of the base 1. A third threaded rod 602 is threadedly connected to the mounting base 601, and a second limiting plate 603 is rotatably mounted on one end of the third threaded rod 602. It should be noted that, during use, rotating the third threaded rod 602 can drive the second limiting plate 603 to move, thereby causing the second limiting plate 603 to come close to the edge of the plastic shell.

[0032] Specifically, the working principle of this fixing device for drilling holes in plastic housings is as follows: During use, the position of the elastic support mechanism 4 is adjusted according to the hole position of the plastic housing through the adjusting plate 3 and the through hole 7. Then, the plastic housing is fixed to the top of the adjusting plate 3 through the fixing mechanism 5. The elastic support mechanism 4 will adaptively support the inner wall of the plastic housing under its own elastic force, so that the first limiting plate 2, the first adjustable limiting mechanism 6 and the second adjustable limiting mechanism 8 abut against the edge of the plastic housing for positioning. After drilling, when processing the same plastic housing again, it is placed between the first limiting plate 2, the first adjustable limiting mechanism 6 and the second adjustable limiting mechanism 8, and then fixed by the fixing mechanism 5. There is no need to adjust the position of the elastic support mechanism 4 again.
