Description

Vapour-pressure type engraving utensil

Technical field

The utility model relates to a kind of engraving utensil, refers to a kind of vapour-pressure type engraving utensil especially.

Background technology

Abundant along with material life, the modern has than the time in leisure to be engaged in art activity, and engraving then is the activity that some people liked.Divide according to material, engraving then is divided into several fields again, as stone carving, woodcarving, ice sculpture, and the engraving of potted plant trees; No matter and be above-mentioned which kind of the engraving, accurately the turnover of lines is delineated out, the concavo-convex level of shape is engraved shaping, the beginning can be carved out lifelike works, the engraving utensil then playing the part of important role.See also shown in Figure 1, it is one to have carved the potted plant trees 10 of finishing, the engraving of the potted plant trees 10 of this kind, be the direction of growth of adjustment its trunk proper or its bark part divested or undercuted concaveconvex shape or shown in Figure 1 according to the growth form of trees, rear side trunk in the trunk position 12 that forms ring-type gives sawing again and is modified into spiral shell and executes shape; The centre position of this spire 11 is again to lower recess.See also shown in Figure 2, it is the hand sawing-machine 20 that a kind of known electric power formula is driven by motor, it is to grip for user's both hands with lever 21 and grip part 22, and (this is a universal architecture to order about internal motor and gear with electric power, do not give unnecessary details for this reason) transmission, and abrasive sheet 23 high speed rotating on making, treating carving with abrasive sheet 23 again carves, yet, this hand sawing-machine 20 is excessive because of volume, only can do rough lines cutting, and is inapplicable to 11 of above-mentioned spires, and the mounting direction of its abrasive sheet 23 is vertical with user's sight line, causes the position that the user can't align the desire cutting accurately.Again, if this known electric power formula hand sawing-machine 20 cuts to hard material accidentally, because of this hand sawing-machine 20 is to drive with motor, this abrasive sheet 23 can't stop automatically, is make 20 couples of users' of hand sawing-machine hand impose a reaction force, and makes the user that hand is sprained, and if this reaction force is excessive, the user must decontrol hand sawing-machine 20, if it is too late to dodge, the hand sawing-machine 20 in the rotation that will be dropped is hindered.Please consult shown in Figure 3 again, it is a kind of hand sawing-machine 30 that drives with air pressure, its terminal flexible pipe 31 that connects an air feed, its proximal end place is provided with an air valve 32 to open and close whether entering of gas, the outer ring surface of this hand sawing-machine 30 is provided with a switch 33 that supplies the user to push again, size with the control gas flow, be protruding to outside rotating shaft 34 high speed rotating from inside and drive hand sawing-machine 30 with air pressure, establish the saw blade 35 that is fixed in rotating shaft 34 front ends with group again and treat the carving engraving, should be with the hand sawing-machine 30 of air pressure driving, during use, if cut to hard material, saw blade 35 can stop and the tool security automatically, and organize the volume of establishing saw blade 35 places and also significantly dwindle, yet the mounting direction of its saw blade 35 still fails to be positioned at same direction with user's sight line, still can't cut accurately some trickle lines, and its position that can grip is too in narrow and bad operation.Please consult shown in Figure 4 again, it is the improvement of the third known hand sawing-machine 40, its end also is to connect a flexible pipe 41 air feed, its outer ring surface also is provided with the size of a switch 42 with the control gas flow, it is protruding to outside rotating shaft (figure does not show) and then organizes the bevel gears (figure does not show) of establishing one 45 degree from inside, this bevel gear is fixed in the bevel gears engagement of 45 degree in the rotating shaft 44 in addition that becomes vertical with it again with an assembling, thereby can drive this horizontal rotating shaft 44 rotates, make the saw blade 45 that horizontal rotating shaft 44 front ends are fixed in assembling become same direction with user's sight line, make the user align the position of desire cutting accurately, yet, this the third known hand sawing-machine 40, because of it is to be positioned at same horizontal level for the position that the conversion of position of assembling saw blade 45 and two rotating shafts turns to, and laterally rotating shaft 44 must can be placed in the bearing block 43 enough wheelbase beginnings of tool, and saw blade 45 must be clamped and fastened in the chuck of rotating shaft 44 front ends, it is excessive to the distance of 43 of bearing blocks to cause saw blade 45, and the space of circling round of causing it to need is bigger, spire 11 to ring-type trunk 12 rear sides that are positioned at potted plant trees 10, then can't carve, and in its when operation, still be difficult for gripping, more seriously, this saw blade 45 is amesiality, saw blade 45 is contacted with when treating carving at a high speed, can cause the situation towards saw blade 45 directions upsets, causing can't this hand sawing-machine 40 of normal running; Be with, above-mentioned three kinds of known hand sawing-machines, the demand when not being inconsistent engraving in fact, and remain to be improved.
