Specifically, the second threaded hole is located at the upper and lower ends of the right side of the second door body, and the door handle mechanism is located on the left side of the first door body.

[0042] It should be noted that when the safety gate is installed on the external door frame and the distance between the door handle mechanism 3 and the door frame mechanism 1 needs to be fine-tuned, the nut 39 can be rotated to move the nut 39 away from the end of the second threaded hole, and then the safety gate can be fine-tuned by rotating the rotating screw 38 through a tool. After adjustment, the nut 39 can be rotated again so that the nut 39 is close to one side of the door body 4.

[0043] Preferably, in the process of adjusting the width of the door barrier mechanism 2, in order to reduce the friction between the door body 4 and the ground and support the door body 4 so that the width adjustment of the door barrier mechanism 2 is smoother, a pulley structure 25 is provided on the lower side of the door body 4, and the pulley structure 25 and the door handle mechanism 3 are located on the same door body 4. The pulley structure 25 is fixed to the door body 4 by screws.

[0044] The working principle of the utility model is roughly as follows: when installing the safety gate fence, a bracket (second bracket) hinged to the gate fence mechanism 2 through the hinge shaft 26 and the rotating shaft sleeve 27 can be first fixed to one side wall of the outer door frame through screws and other fixing parts, and then another bracket (first bracket) can be fixed to the other side wall of the outer door frame, and then the bolt structure 8 is rotated to separate the bolt structure 8 from the fixing holes 6 of the two door bodies 4, and then a door body 4 (first door body) with a handle 13 is moved along the width direction to adjust to a suitable width, and then the bolt structure 8 is rotated so that the bolt structure 8 is successively penetrated through the first threaded hole 10, the fixing hole 6, the avoidance hole 11 and the fixing hole 6 and then abuts against the groove, and then a tool can be used to rotate the rotating screw 38 to achieve fine-tuning of the gate fence mechanism 2 to the door frame mechanism 1, so that the limiting hole on the fixing sleeve 12 can be plugged into the limiting protrusion 21 on the handle 13, thereby completing the installation of the safety gate fence. The above installation sequence is not unique and can be adjusted according to habit.

[0045] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
