[0024] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] The present application embodiment provides a tool for screwing, referring to Figure 1 and Figure 2 A screw-mounting tool comprises an upper die 1 and a lower die 2, which are connected by flipping. Specifically, the upper die 1 and the lower die 2 are connected by a self-locking hinge. A fixing groove 21 is provided on the side wall of the lower die 2 facing the upper die 1, and a plurality of fixing grooves 21 can be provided to improve the screw installation efficiency; a plurality of clamping blocks 22 are also fixed on the side wall of the lower die 2 facing the upper die 1 corresponding to each fixing groove 21, and a clamping block 22 is fixed at least at the diagonal position of each fixing groove 21.

[0027] Reference Figure 1 and Figure 2 The tooling provided in the present application is used to realize the installation of a fastening screw 100 of a specific electrical component, and to realize the installation connection between the first mounting member 200 and the second mounting member 300 by the fastening screw 100. Specifically, the first mounting member 200 is placed in the fixing groove 21, and the shape of the fixing groove 21 matches the shape contour of the first mounting member 200. After the first mounting member 200 is placed in the fixing groove 21, the top of the first mounting member 200 protrudes from the surface of the upper mold 1; the second mounting member 300 is placed above the first mounting member 200, and the second mounting member 300 is simultaneously abutted against multiple blocks 22, and the horizontal displacement of the second mounting member 300 is limited by the multiple blocks 22.

[0028] Reference Figure 1 and Figure 2, the upper die 1 is provided with a limit hole 11, the number and position of the limit hole 11 correspond to the fixed groove 21, and a guide sleeve 3 is installed in each limit hole 11. When the first mounting member 200 and the second mounting member 300 are installed on the lower die 2, and the upper die 1 is buckled on the upper part of the lower die 2, the limit hole 11 is located directly above the fixed point. A fastening screw 100 is placed in the guide sleeve 3, and the difference between the inner diameter of the guide sleeve 3 and the outer diameter of the head of the fastening screw 100 is less than the error value A. The fastening screw 100 is drilled along the guide sleeve 3 using an electric drill or other tools, and the vertical installation of the fastening screw 100 can be achieved. The error value A can be determined according to the vertical installation accuracy requirements of the fastening screw 100 of different electrical components.

[0029] Specifically, refer to Figure 1 and Figure 2 After the upper mold 1 and the lower mold 2 are buckled together, there is a gap between the opposite side walls of the upper mold 1 and the lower mold 2, and an operating part 12 is provided on the side wall of the lower mold 2 protruding from the side of the upper mold 1 away from the rotating end. The upper mold 1 and the lower mold 2 are flipped and connected through a self-locking hinge, which enables the staff to operate the tooling of the present application with one hand, making the operation more convenient and efficient.

[0030] Further, see Figure 1 and Figure 2 The guide sleeve 3 protrudes from the side of the upper mold 1 toward the lower mold 2, and when the upper mold 1 and the lower mold 2 are buckled, the end face of the guide sleeve 3 is as close to the surface of the second mounting member 300 as possible, thereby shortening the gap between the guide sleeve 3 and the surface of the second mounting member 300, so that the guide sleeve 3 can remain in a vertical state as much as possible during the entire installation process of the fastening screw 100.

[0031] Preferably, refer to Figure 1 and Figure 2 The length of the guide sleeve 3 is greater than the thickness of the upper mold 1, and the guide sleeve 3 is threadedly connected to the side wall of the limiting hole 11. By rotating the guide sleeve 3, the distance between the end face of the guide sleeve 3 and the surface of the second mounting member 300 can be adjusted. For the first mounting member 200 or the second mounting member 300 with different thicknesses, or adding other mounting members between the first mounting member 200 and the second mounting member 300, adaptation can be achieved by adjusting the position of the guide sleeve 3, thereby improving the scope of application of the tooling of the present application.

[0032] In addition, refer to Figure 1 and Figure 2, a positioning groove 23 is also provided at a corner of the side of the lower mold 2 away from the rotating end, and positioning blocks 13 are fixed at the corresponding corners of the upper mold 1 and the lower mold 2. When the upper mold 1 and the lower mold 2 are buckled, the positioning blocks 13 are correspondingly inserted into the positioning grooves 23, and there are gaps between the positioning blocks 13 and each side wall of the positioning grooves 23. A gap is set between the positioning blocks 13 and the side walls of the positioning grooves 23, so that when the upper mold 1 is buckled onto the lower mold 2, the positioning blocks 13 and the lower mold 2 do not interfere with each other, and the upper mold 1 is smoothly buckled; at the same time, the positioning blocks 13 and the positioning grooves 23 are set, so that when the upper mold 1 is buckled with the lower mold 2, the positioning accuracy can be improved, so that the guide sleeve 3 and the fixed point can be aligned.

[0033] In a preferred embodiment, a pair of pick-up and release grooves 24 are also provided on the surface of the lower mold 2 facing the upper mold 1, and the pick-up and release grooves 24 are provided on two opposite sides of the fixed groove 21 and are connected to the fixed groove 21; the pick-up and release grooves 24 are provided so that the operator can more conveniently remove the first mounting member 200 from the fixed groove 21.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
