Further, described cutting guide frame comprises and the spigot surface of altitude datum Plane intersects that described burning torch and spigot surface are slidingly matched; Described spigot surface is made of the guiding ruler side, and described altitude datum face is made of the guiding ruler end face.

Further, described cutting guide frame comprises the slide block structure of fixedlying connected with burning torch, and described slide block structure comprises guide runner, and described burning torch is slidingly matched by guide runner and spigot surface.

Further, described slide block structure comprises the position limiting slide block that is slidingly matched with the altitude datum face, the height adjusting structure of position limiting slide block, determines the height of burning torch by position limiting slide block and cooperating of altitude datum plane; Described position limiting slide block links to each other with burning torch by height adjusting structure.

As a kind of preferred, described slide block structure is the inverted L shape slide block, one side described guide runner and position limiting slide block constituting by the inverted L shape slide block respectively; Described inverted L shape slide block is fixedlyed connected with burning torch by detachable fixed structure, and the height adjusting structure of described position limiting slide block is made of this detachable fixed structure.

As a kind of preferred, described dismounting syndeton is the clip by screw lock.

As a kind of preferred, described cushion block is made of magnet.

The beneficial effects of the utility model are: during cutting, burning torch moves along the cutting guide frame, guarantees the linearity and the perpendicularity of cut surface, has avoided the artificial hand-held problem that is difficult to stablize burning torch; Simultaneously, in motion process, make that by the altitude datum plane spacing is constant between burning torch and the surface of the work, guaranteed that effectively cutting speed is stable.Therefore, manually cut by this device and can avoid the cut quality problem that causes owing to the manually-operated reason substantially, satisfy the design specification requirement, guarantee cut quality.The allowance of the following process of reserving is little, the stock utilization height, and the allowance of following process is little, and the material-saving of saving trouble saves time.Above-mentioned cushion block has then guaranteed the distance between guiding ruler 1 and the workpiece, avoids the damage of cutting flame team guiding ruler.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is a side view of the present utility model;

Fig. 3 is a vertical view of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 2, shown in Figure 3, hand cut device of the present utility model, comprise burning torch 4, be provided with guiding ruler 1, one of them side of described guiding ruler 1 is provided with the altitude datum plane of definite burning torch 4 height and the cutting guide frame of definite burning torch 4 cutting paths, and extend along the cutting guide frame on described altitude datum plane; Described guiding ruler 1 end face 11 is fixed with handle 2, bottom surface 12 is provided with at least two cushion blocks; Described burning torch 4 links to each other with guiding ruler 1 by the cutting guide frame.

During cutting, burning torch 4 moves along the cutting guide frame, guarantees the linearity and the perpendicularity of cut surface, has avoided the artificial hand-held problem that is difficult to stablize burning torch 4; Simultaneously, in motion process, make that by the altitude datum plane spacing is constant between burning torch 4 and the surface of the work, guaranteed that effectively cutting speed is stable.Therefore, manually cut by this device and can avoid the cut quality problem that causes owing to the manually-operated reason substantially, satisfy the design specification requirement, guarantee cut quality.The allowance of the following process of reserving is little, the stock utilization height, and the allowance of following process is little, and the material-saving of saving trouble saves time.Above-mentioned cushion block has then guaranteed the distance between guiding ruler 1 and the workpiece, avoids the damage of cutting flame team guiding ruler 1.

Observe the cutting situation for convenience, simultaneously for simplified structure, described cutting guide frame comprises the spigot surface 13 with the altitude datum Plane intersects, and described burning torch 4 is slidingly matched with spigot surface 13; Described spigot surface 13 is made of guiding ruler 1 side, and described altitude datum face is made of guiding ruler 1 end face 13.Directly burning torch 4 is leaned against on the spigot surface 13 during use, and slide along spigot surface 13.Owing in the cutting process, influenced by cutting flame, to stablize higherly, said structure is simple, so reliability is also high.
