本实用新型的目的就是要解决上述问题，提供一种新型套管固定装置。通过转动手柄固定套管的方式，提高了工作效率牢固可靠且拆卸方便The purpose of this utility model is to solve the above problems and provide a novel casing fixing device. By turning the handle to fix the sleeve, the work efficiency is improved. It is firm, reliable and easy to disassemble.

本实用新型所采取的技术方案是：The technical scheme that the utility model takes is:

新型套管固定装置，包括上固定夹板、通丝螺杆和套管，套管设置在上固定夹板下方并与其下表面相连接，通丝螺杆下端从上固定夹板上穿入并延伸到套管中，通丝螺杆与上固定夹板之间滑动连接，其特征在于，在上固定夹板下方的套管中还设有下固定夹板，前述通丝螺杆下端穿过下固定夹板并与其滑动链接，所述下固定夹板大小与套管内径相配合；A new casing fixing device, including an upper fixing splint, a threaded screw and a casing, the casing is arranged under the upper fixing splint and connected to its lower surface, and the lower end of the threaded screw penetrates from the upper fixing splint and extends into the casing , the sliding connection between the threaded screw and the upper fixed splint is characterized in that a lower fixed splint is also provided in the sleeve below the upper fixed splint, and the lower end of the aforementioned through threaded screw passes through the lower fixed splint and is slidably linked with it, the The size of the lower fixing splint matches the inner diameter of the casing;

在上固定夹板的上表面设有手拧螺母，该手拧螺母与通丝螺杆之间螺纹配合连接；A hand-tightened nut is provided on the upper surface of the upper fixing splint, and the hand-tightened nut is threadedly connected with the threaded screw rod;

在上固定夹板的上表面和下表面也分别设置有手拧螺母，手拧螺母与通丝螺杆之间螺纹配合连接。Thumb nuts are respectively arranged on the upper surface and the lower surface of the upper fixing splint, and the thumb nuts are threadedly connected with the threaded screw.

在通丝螺杆的最上端设置有用于控制通丝螺杆的手柄，该手柄与通丝螺杆相垂直设置。A handle for controlling the through screw is arranged on the uppermost end of the through screw, and the handle is vertically arranged with the through screw.

上固定夹板和下固定夹板之间平行设置，且通丝螺杆分别传过上固定夹板和下固定夹板的中心部位。The upper fixing splint and the lower fixing splint are arranged in parallel, and the threaded screw passes through the central parts of the upper fixing splint and the lower fixing splint respectively.

通丝螺杆的最下端设置为带有螺纹的锥形形状。The lowermost end of the threaded screw rod is set in a tapered shape with threads.

本实用新型通过螺丝替代铁钉，固定在模板上，安装及拆卸时仅需旋转手柄即可。同时对模板的破坏降低到最低。在螺杆中间增加固定夹板，可防止套管晃动。The utility model replaces iron nails with screws, and is fixed on the formwork, and only needs to rotate the handle during installation and disassembly. At the same time, the damage to the formwork is reduced to a minimum. A fixed splint is added in the middle of the screw to prevent the casing from shaking.

本实用新型的有益效果：The beneficial effects of the utility model:

1、节省时间，方便安装及拆卸，重复使用率高。1. Save time, easy to install and disassemble, high reuse rate.

2、原理简单，就地取材，模板破坏小。2. The principle is simple, local materials are used, and the damage to the formwork is small.
