In use, the first rotating mechanism 4 can be driven first so that the first rotating mechanism 4 is rotated so as to drive
Slipping block 5 within mounting rail 2 is subjected to displacement, and is moved past in place in the position of horizontal level this makes it possible to control scale 8
Cheng Zhong, because annular tooth 11 engages with bar shaped tooth 9, such bar shaped tooth 9 will enter line slip in the between cog of annular tooth 11, no
Normal use adjustment can be influenceed.
Simultaneously can be by driving the second rotating mechanism 12 so that rotating cylinder 10 also rotates, so that annular tooth
11 drive bar shaped teeth 9, can thus control position of the scale 8 on vertical.
The first transmission mechanism and the second transmission mechanism can also be driven simultaneously, while adjusts horizontally and vertically position, so
Can enables scale 8 to be displaced on any position.
When needing picture oblique line, the 3rd rotating mechanism 20 can be driven so that the 3rd drive 15 rotates, and passes through
Two driving belts 17 drive the second drive 141 to be rotated, and in the rotation process of the second drive 141, pass through the first transmission
Belt 16, the first drive 14 is driven to be rotated, so as to drive bevel 13 to rotate so as to form an oblique line, thus
Angle of inclination can be turned to as required, and the oblique line of needs is drawn according to bevel 13.
, can be during regulation scale 8 due to the setting of the first hinge bar 18 and the second hinge bar 19, the 3rd transmission
Wheel 15 is integrally fixed on wall, and the first drive 14 and the second drive 141 are relative motions, the first hinge bar 18 and the
Two hinge bars 19 are all hinged on the first drive 14, the second drive 141, on the 3rd drive 15, on the one hand can risen
The supporting role for giving the first drive 14 and the second drive 141 to one, on the other hand, the energy in the motion process of scale 8
Enough so that the situation spacing that relative displacement also occurs for the first drive 14 and the second drive 141 will not change.
By the setting of holding tank 21, the receiving effect for bevel 13 can be played so that uncomfortable used in bevel 13
It can be housed in holding tank 21 in journey, save space so that overall structure is smaller, while inserting groove 22 and inserted block 23
Coordinate so that the first drive 14 can drive bevel 13 to move in motion process, the shape choosing of inserting groove 22 and inserted block 23
It is more suitable with regular polygon prism.
By the setting of the first sliding shoe 25 and the second sliding shoe 28, chalk directly can be inserted into the first chalk jack
26 and second in chalk jack 29, directly allows the first sliding shoe 25 or the second sliding shoe 28 to be slided in the first sliding groove or second
Enter line slip in groove, it is possible to directly draw more neat straight line and oblique line.So that using more convenient.
Pass through the cooperation of pellet 32 and caulking groove 33 so that in the first sliding shoe 25 and the second sliding shoe 28 in use
There is a position-limiting action, can be limited during impracticable, will not arbitrarily be slided.
By the cooperation of limited block 34 and stopper slot 35, slipping block 5 is enabled to be not easily disconnected from, make in installation process
Obtain more stable in slipping.
By the way that limited block 34 and stopper slot 35 are set in echelon, it can further strengthen position-limiting action.
Clockwise and anticlockwise motor is more conventional motor, and the function of rotating can be directly realized by switch.
By the setting of first annular groove 36, the second annular groove 37, the 3rd annular groove 38, fourth annular groove 381, can make
The first driving belt 16 and the second driving belt 17 fix it is more firm.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
