[0002] In the prior art, when the door frame is processed, there is more or less the phenomenon that the space inside the door frame is too small. The method of shaping is generally to hit with a hammer, which makes the staff need to spend a lot of effort and skill to correct the door frame. At the same time , using this method to correct the door frame is not very accurate, and it is easy to cause deformation of the door frame due to excessive force

Embodiment Construction
[0015] Now in conjunction with accompanying drawing, the present invention will be further described:
[0016] Such as figure 1 As shown, a door frame inner hollow bracket includes: a manual main rod 1 and an auxiliary rod 4, one end of the manual main rod 1 is a hand-held part, the other end is a first correction end, and one end of the auxiliary rod 4 is hinged on the first correction end. Near the end, the other end is the second correcting end, and the manual main rod 1 and auxiliary rod 4 constitute a lever structure.
[0017] The first correcting end is fixed with a main correcting cross bar 5 perpendicular to the manual main bar 1 .
[0018] The second correction end is fixed with a secondary correction cross bar 2 perpendicular to the secondary rod 4 .
[0019] The main correction cross bar 5 and the auxiliary correction cross bar 2 are round bars.
[0020] A limiting plate 3 for controlling the angle between the manual main rod 1 and the auxiliary rod 4 is fixed on...

The invention discloses a door frame inner-space bracket, which comprises a manual main rod and an auxiliary rod, wherein one end of the manual main rod is a handheld part, and the other end of the manual main rod is a first correcting end; one end of the auxiliary rod is hinged in the position near the first correcting end, and the other end of the auxiliary rod is a second correcting end; the manual main rod and the auxiliary rod form a lever structure; a main correcting cross rod perpendicular to the manual main rod is fixed at the first correcting end, and an auxiliary correcting cross rod perpendicular to the auxiliary rod is fixed at the second correcting end; the main correcting cross rod and the auxiliary correcting cross rod are circular rods; the auxiliary rod is fixed with a limiting plate used for controlling the included angle between the manual main rod and the auxiliary rod; and correspondingly, the manual main rod is fixed with a limiting rod, which comprises a stop screw, a first nut and a second nut, and the stop screw penetrates through a through hole in the manual main rod, and is tightly clamped and fixed by the first nut and the second nut. The door frame inner-space bracket has the benefits of simple structure, low cost, convenience and labor saving in operation, strong practicability and high operating efficiency.
Description
technical field [0001] The invention relates to a tool for door industry manufacturing, especially a tool for designing door frame processing. Background technique [0002] In the prior art, when the door frame is processed, there is more or less the phenomenon that the space inside the door frame is too small. The method of shaping is generally to hit with a hammer, which makes the staff need to spend a lot of effort and skill to correct the door frame. At the same time However, it is not very accurate to use this method to correct the door frame, and it is easy to deform the door frame due to excessive force. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention proposes a door frame inner hollow brace, which corrects the size reduction of the door frame by using the principle of leverage. [0004] Technical scheme of the present invention is: [0005] A door frame inner hollow bracket, comprising: a manual main rod an...
