After installation, the frame base is horizontally fixed at the top of the door and window frame, the fixed seat is horizontally fixed at the top of the door and window sash, and both ends of the transmission bar are respectively connected to other hardware. Different floors have different heights, and users have different requirements for the ventilation volume of the door and window. However, this kind of diagonal tie rod has only one gear and can only realize the inward tilting opening and positioning of the door and window sash at a fixed angle, and cannot meet the multi-angle opening requirements of users for the door and window sash. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a diagonal tie rod with an arbitrarily positionable opening angle in view of the deficiencies of the prior art. The diagonal tie rod can realize the positioning of any opening angle, and while realizing the adjustment of different gears of the door and window sash, it can realize the stepless inward tilting of the door and window sash, so as to meet the different requirements of users on different floors for the ventilation volume of the inward tilting doors and windows.

[0004] The technical solution adopted by the present utility model to solve the above technical problems is as follows: An inclined pull rod with an arbitrarily positionable opening angle, comprising a frame base, a first support piece, a second support piece, a long pull rod, a short pull rod, a transmission bar and a fixed seat. One end of the first support piece is riveted to the middle of the frame base, and the other end of the first support piece is riveted to one end of the long pull rod. Both ends of the second support piece are respectively slidably connected to the frame base and the long pull rod, and the middle of the second support piece is cross-riveted to the middle of the first support piece. The other end of the long pull rod is slidably connected to the fixed seat. The transmission bar is slidably installed through the fixed seat in the left-right direction. An eccentric locking point is installed on the transmission bar, and a locking block cooperating with the eccentric locking point is fixed on the long pull rod. One end of the short pull rod is riveted to the long pull rod, and a positioning mechanism for positioning any opening angle of the inclined pull rod is arranged between the short pull rod and the fixed seat. The positioning mechanism comprises a gear, a steel ball, a positioning spring and a cylindrical head adjusting screw.
