[0023] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0024] Example

[0025] See also Figures 1 to 7 In this embodiment, a hand drill BV line end paralleling tool is provided, including a casing 1, a core protection shaft 2 and a connecting rod 3. The core protection shaft 2 is arranged inside the casing 1, and the core protection shaft 2 and the casing 1 are detachably connected. The core protection shaft 2 is inserted into the casing 1, and the two can be separated. An outer bell mouth 11 is provided at one end of the casing 1, and the connecting rod 3 is threadedly installed at the other end. After one end of the connecting rod 3 is installed in the casing 1, it can limit the core protection shaft 2, thereby limiting and fixing the core protection shaft 2, and the end of the connecting rod 3 away from the casing 1 is connected and fixed to the electric drill, so that when in use, after the electric drill is started, it drives the connecting rod 3 to rotate together, and the connecting rod 3 can drive the casing 1 and the core protection shaft 2 to rotate together, and the line paralleling operation can be achieved when the casing 1 rotates;

[0026] Specifically, a vertical groove 13 is provided at one end of the outer bell mouth 11 of the casing 1, and an arc-shaped groove 14 is provided on the inner side of the vertical groove 13. The vertical groove 13 is connected to the arc-shaped groove 14 and together constitutes a parallel line groove. At the same time, the inner wall of the outer bell mouth 11 is provided with a chamfer. During the parallel line operation, one wire is placed in the parallel line groove, and the other wires are inserted into the casing 1. The design of the chamfer and the outer bell mouth 11 are conducive to the insertion of the wires. After the wires are placed, the electric drill is used as the power source to drive the casing 1 to rotate through the connecting rod 3, thereby realizing the automated parallel line operation. Compared with manual operation, the speed is faster, the efficiency is higher, the effect is better, and the dense and tight parallel line effect can be achieved.

[0027] Moreover, a step 12 is provided at one end of the sleeve 1 near the parallel groove. The core protection shaft 2 is located in the sleeve 1, with one end thereof limited by the step 12 and the other end limited by the connecting rod 3. The core protection shaft 2 is fixed by the cooperation of the step 12 and the connecting rod 3.

[0028] The interior of the core protection shaft 2 is also vacuum, and its interior is a through-hole design, and an inner bell mouth 21 is provided at one end thereof close to the step 12. When paralleling, except for the wound wires, other wires will enter the through-hole of the core protection shaft 2 after being inserted into the sleeve 1, and the inner bell mouth 21 also plays a role in avoiding obstruction of the wires, facilitating better insertion of the wires;

[0029] An internal thread 15 is provided on the inner wall of the end of the sleeve 1 away from the step 12. The sleeve 1 is threadedly connected to the connecting rod 3 through the internal thread 15. The connecting rod 3 includes a mounting rod 31 and a screw 32. The mounting rod 31 is fixed to the electric drill, and a screw 32 is provided at one end of the mounting rod 31. The screw 32 is adapted to the internal thread 15 of the sleeve 1 to achieve the installation of the connecting rod 3. At the same time, it is also convenient for disassembly, and the core shaft 2 can be installed and removed.

[0030] The mounting rod 31 may be cylindrical, with a circular cross section (e.g. Figure 1 、 Figure 2 As shown), it can also be set as a columnar structure with a hexagonal cross section (as shown Figure 7 As shown), it can also be set to a columnar structure with a triangular cross-section, which is mainly compatible with an electric drill and can be determined according to actual installation requirements.

[0031] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
