Description

Technical Field

[0001] The deep hole sleeve driving rod of the present invention is mainly used for the driving head and driving tool of the deep hole sleeve driving rod, which can be quickly disassembled and assembled; at the same time, the true circle and coaxial accuracy between the deep hole sleeve driving rod, the driving head and the driving tool can be ensured technically, and no yaw or shaking will occur during operation. Background Art

[0002] Generally, the installation of air-conditioning ventilation pipes or fire-fighting pipes mainly involves installing multiple bolts arranged in pairs at appropriate positions on the ceiling, and inserting a horizontally arranged support plate between the two bolts. After adjusting the height of the support plate, two nuts are locked and fixed in the two bolts, so that the air-conditioning ventilation pipes or fire-fighting pipes can be installed on the support plate.

[0003] However, since the bolt is located at a high position and is very long, if the construction worker uses a general socket wrench tool to lock or remove the nut, he must climb up and down with a ladder, and must tighten or loosen the nut over a long distance, which makes the entire construction process quite troublesome and inconvenient. Therefore, a deep hole socket drive rod has been developed for the locking and fixing process of the bolt and the nut.

[0004] The traditional deep hole sleeve driving rod available on the market mainly has a driving head at the head end of a straight tube with an appropriate length, a connecting head is provided at the tail end of the straight tube by welding or heat melting, and then the straight tube and the connecting head are processed into one piece by grinding and polishing. The driving head is driven and rotated by an electric tool to directly assemble or disassemble the nut.

[0005] The conventional deep hole sleeve driving rod has at least the following existing problems and defects in actual operation and use that need to be overcome and solved.

[0006] First, the true circle and coaxial accuracy between the straight tube and the connector are poor, and during actual operation, it is easy for the straight tube to sway or shake.

[0007] Second, the straight tube, the drive head and the connector are integrally formed, and cannot be used to disassemble or assemble nuts of various sizes and specifications, and has a narrow scope of application.

[0008] 3. When the straight tube or the connector is broken (at the joint of the electric tool) or the driving head is worn out (at the joint of the nut), the whole thing must be scrapped, which is quite wasteful and not economically efficient. Summary of the invention

[0009] The inventor is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and insights. In view of the existing problems and defects of traditional deep hole sleeve driving rods, he actively invested in the spirit of innovation and improvement to complete the deep hole sleeve driving rod.

[0010] The technical means used by the invention to solve the problem are: two sleeve parts are provided at the head and tail ends of the hollow tube body, and two sleeve hole grooves are provided inside the two sleeve parts for sleeve connection of the drive head and the connector. The outer part of the sleeve part is provided with an external thread for locking and fixing the quick-disassembly nut. A fixed cap is provided at the outer end of the quick-disassembly nut. The fixed cap and the drive head and the connector are provided with corresponding inner steps and positioning steps. The quick-disassembly nut is used to drive the fixed cap to be positioned on the drive head and the connector. In addition to avoiding the locking of the quick-disassembly nut, the drive head and the connector can also be prevented from loosening due to the vibration of the electric tool. At the same time, the true circle and coaxial center accuracy between the hollow tube body and the drive head and the drive tool are high. In actual operation, there will be no yaw and shaking, so the purpose of quickly assembling and disassembling the drive head and the connector is achieved.

[0011] The invention has the following effects compared with the prior art:

[0012] First, the true circle and coaxial center between the hollow tube body, the drive head and the drive tool are of high precision, and no yaw or shaking will occur during actual operation.

[0013] Second, the hollow tube body, the driving head and the connecting head are detachable, and the driving heads and the connecting heads of various sizes and specifications can be quickly disassembled and assembled, which is suitable for disassembling or assembling a variety of nuts and has a wide range of applications.

[0014] 3. When the hollow tube body and the driving head are worn out (nut joint) and the connector is broken (electric tool joint), only the driving head and the connector kit need to be replaced without scrapping the entire tool, which is quite economical.
