[0009] Preferably, the supporting feet are located on both sides of the blocking bolt and are symmetrical to each other, and the height of the supporting feet is such that the blocking bolt is suspended in the air when the supporting feet are erected.

[0010] The utility model has the following beneficial effects: the structure is simple, the cable protection tube is formed by splicing, the protection tube can be bent and extended, and can also be formed into a straight tube with a reinforcement mechanism, the protection tube is easy to assemble and disassemble, and has strong practicality, as follows:

[0011] (1) The utility model is provided with a splicing pipe. When assembling into a protective pipe, the front pipe of the splicing pipe is inserted into the insertion pipe of another splicing pipe. During the insertion process, the blocking bolt is lifted up by the upper paddle, and the supporting feet of the two splicing pipes are placed on the ground so that the blocking bolt is aligned with the sliding rail. After the front pipe is inserted into the slot of the insertion pipe, the blocking bolt is lowered to complete the assembly. Multiple splicing pipes are spliced ​​into a straight pipe to form a protective pipe. When the protective pipe needs to be bent, the splicing pipe at the part that needs to be bent is pulled to separate the front end of the front pipe from the slot. Under the action of the flared wall, the closer the front pipe is to the opening of the insertion pipe, the larger the bending angle between the two splicing pipes is, thereby forming a bent pipe.

[0012] (2) The utility model is provided with a blocking bolt. When the front pipe is inserted into the insertion tube, it is lifted by the upper paddle. When the blocking bolt is lowered, the blocking bolt is rotated to allow the bar rod and the sliding rail to pass through the sliding rail. The bar rod is then rotated to be misaligned with the sliding rail. Under the action of friction, the blocking bolt is not easy to slide with the insertion tube. When the front pipe is pulled outward, the blocking bolt prevents the two splicing pipes from separating, and the two splicing pipes rotate with the blocking bolt as a fulcrum to complete the pipe bending.
