Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a torsion-resistant wire sleeve. Background Technique
[0002] A hair clipper is an electric tool used for trimming and grooming hair. It usually consists of a motor with a rotating blade and can be powered by plugging into a power source. Hair clippers are widely used in places such as homes, barbershops, and beauty salons for cutting hair, trimming edges, trimming beards, etc.
[0003] During the use of the hair clipper, it often bends and twists repeatedly, seriously damaging the service life of the wire. There are often problems such as the wire breaking and losing power during use or the wire being damaged, posing a serious safety risk. Content of the Utility Model
[0004] The purpose of the utility model is to provide a torsion-resistant wire sleeve to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A torsion-resistant wire sleeve includes a plug body and a second wire sleeve body. A protective head is provided inside the plug body. One end of the protective head is connected to a first wire sleeve. A cable is provided inside the first wire sleeve, and one end of the cable is connected to the protective head. The outer surface of the plug body is provided with a second wire sleeve body. A half shell is provided inside the second wire sleeve body. A first screw sleeve is inserted through one end side of the half shell, and a first screw is inserted into the first screw sleeve. A second screw sleeve is inserted through the other end side of the half shell, and a second screw is inserted into the second screw sleeve.
[0006] When using a torsion-resistant curve sleeve in this technical solution, the staff needs to first install the second sleeve body on the plug body. The specific operation is that the staff takes the two half-shells inside the second sleeve body to the side of the plug body, places them on both sides and fits them together, places the first sleeve and the cable inside the plug body between them. After placing them between the two half-shells, the staff uses bolts to fixedly connect the two fixing blocks, and then fixedly connects the two half-shells. After the fixed connection, the staff pinches the two first rotating handles and applies a rotational force. The rotational force applied to the first rotating handle will be synchronized to the first screw rod. The first screw rod will rotate inside the first screw sleeve. Due to the meshing of the threads, the first screw rod will move inside the first screw sleeve. The moving first screw rod will push the clamping plate rotatably connected at one end, and the two clamping plates will shorten the distance between them and snap into the groove, completing the fixation of one end of the second sleeve body. After completing the fixation of one end of the second sleeve body, the staff pinches the second rotating handle and applies a rotational force. The rotational force applied to the second rotating handle will be synchronized to the second screw rod. The second screw rod will rotate inside the second screw sleeve. Due to the meshing of the threads, the second screw rod will move inside the second screw sleeve. The moving second screw rod will push the clamping plate rotatably connected at one end, and the two clamping plates will shorten the distance between them and clamp the cable therebetween, completing the fixation of the other end of the second sleeve body. Finally, the second sleeve body will externally connect and protect the cable and the first sleeve inside the plug body, prevent external pulling and disconnection damage and provide shielding protection, while the internal first sleeve will directly separate the force at the connection between the cable and the protective head, avoiding damage to the cable caused by bending and twisting.
[0007] Preferably, one end of the first screw rod is fixedly connected with a first rotating handle, and the other end of the first screw rod is rotatably connected with a clamping plate. The setting of the first rotating handle makes it convenient for the staff to apply a rotational force to the first screw rod and provides a force application point.
[0008] Preferably, the clamping plate is inserted into the inside of the groove, and the groove is opened on the surface of the first sleeve. Through the cooperation of the clamping plate and the groove, one end of the two half-shells inside the second sleeve body can be fixed on the surface of the first sleeve, achieving the effect of clamping connection. Another function of the groove is that the first sleeve can be bent, facilitating bending together with the cable to prevent the connection between the cable and the protective head from being disconnected and damaged.
[0009] Preferably, one end of the second screw rod is fixedly connected with a second rotating handle, and the other end of the second screw rod is rotatably connected with a clamping plate. The setting of the second rotating handle makes it convenient for the staff to apply a rotational force to the second screw rod and provides a force application point. The setting of the clamping plate enables it to clamp and fix the cable.
[0010] Preferably, there are two semi - shells. Fixed blocks are provided on the top and bottom surfaces at both ends of the two semi - shells, and bolts are inserted into the fixed blocks. The setting of the two semi - shells enables them to wrap the first wire sleeve and the cable inside, achieving the convenience of installing the second wire sleeve body on the surface of the plug body. Through the cooperation of the fixed blocks and the bolts, the two semi - shells can be fixedly connected, achieving the effect of fixed connection.
[0011] Preferably, the other end of the protective head is connected with a blade. The setting of the blade enables the plug body to be inserted into the socket, facilitating the power supply to the cable.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. The present utility model installs a first wire sleeve at the connection between the cable and the protective head. The surface of the first wire sleeve is provided with a groove in a rounded - corner style, which can disperse the force when the cable bends and twists, avoiding damage to the connection between the cable and the protective head. Additionally, a second wire sleeve body is installed on its outer surface. The second wire sleeve body can directly connect the first wire sleeve and the cable, avoiding damage caused by external pulling and disconnection and providing shielding protection.
