Column, the stud are fixedly connected with No. two gear rack sections, and the gear rack passes through screw hole and spiral shell by No.1 gear rack section and No. two gear rack sections
Column is formed by connecting.
Further, No. two gear rack sections are equipped with several groups, and No. two gear rack sections are connected by screw hole and stud head and the tail.
Further, the No.1 gear rack section and No. two gear rack Duan Jun include inner cylinder and outer cylindrical body, the inner cylinder and
Outer cylindrical body is fixedly connected and inner cylinder and column jacket body support frame are equipped with reinforcing rib, and reinforcing rib is fixedly connected on inner cylinder and outer
Between cylinder.
Further, it is equipped with screw thread on the screw hole inner wall, seal gasket is embedded in the screw thread.
Compared with prior art, the utility model has the advantages that：
1, the utility model is by being arranged No.1 gear rack section and No. two gear rack sections, and utilizes stud and screw hole by No.1 gear rack
Section and No. two gear rack sections are combined connection, can the length appropriate that gear rack be increased, easy to use, convenient disassembly, convenient for taking
Band, flexibility are good.
2, on the one hand the utility model can increase No.1 gear rack by being equipped with reinforcing rib between inner cylinder and outer cylindrical body
On the other hand the intensity of section and No. two gear rack sections changes the solid construction of gear rack to increase the intensity of gear rack entirety, reduce
The weight of gear rack saves material.
3, the utility model is equipped with seal gasket by embedded on the screw thread of screw hole inner wall, can make No.1 gear rack section and
No. two gear rack sections are completely embedded, not easily to fall off, and safety and stability is high.
