Compared with the related art, the spliced guardrail provided by the utility model has the following beneficial effects:

By turning the handle, the first gear is rotated, and because the first gear is meshed with the second gear, the second gear can be driven to rotate, causing the threaded rod to rotate. Under the action of the limit rod and the slider, the movable plate can be moved vertically up and down along the surface of the threaded rod, and under the action of the support rod, the position of the auxiliary plate can be adjusted. After the auxiliary plate is adjusted to a suitable position, stop turning the handle, and the position of the auxiliary plate can be adjusted according to the usage situation, so that the height intercepted by the guardrail as a whole can be adjusted, so that the guardrail can be suitable for various places, increasing the applicability of the guardrail.

By inserting the fixing block into the fixing groove, the block can be moved along the surface of the fixing block because it is a double-sided trapezoidal setting. At the same time, under the action of the spring, the block can be inserted into the groove to form a fixing effect, which can form a splicing effect between the columns. The operation is simple and can be operated by oneself. Compared with traditional guardrail splicing, it is faster and can greatly reduce the time required for workers to splice guardrails, thereby improving overall work efficiency.
