When, connecting rod 18 can also slide to the left or to the right with two horizontal round bars 9, at this moment pointer II19 can on ruler II20 to the left or
Person slides to the right, accurately controls two horizontal round bars, 9, two saddles according to the pointer II19 scale number on ruler II20 of passing by
6 and the distance slided to the left or to the right of two slide track bars 5, and then accurately control the length that detail pen 2 draws horizontal line.
Specific embodiment 9:
Illustrate that present embodiment, the round seat 1 can be fixed at any time when moving in left and right directions below with reference to Fig. 1-11
Mode are as follows:
Fastening screw I is connected through a screw thread on two saddles 6, two fastening screw I are by holding out against in rectangle frame 10
On mode two saddles 6 are fixed, and then round seat 1 is fixed in the lateral direction；As shown in the A in Figure 11；
Alternatively, the position that is slidably connected of two plush coppers 11 and two horizontal round bars 9 is provided with non-slip mat, by frictional force by two
A horizontal round bar 9 is fixed, and then round seat 1 is fixed in the lateral direction；As shown in the B in Figure 11；
Alternatively, being slidably connected on ruler II20 there are two sliding block 21, two sliding blocks 21 are located at the left and right two of connecting rod 18
Side has been connected through a screw thread fastening screw II on two sliding blocks 21, and two two sliding blocks 21 are fitted in a left side for connecting rod 18 respectively
Right two sides, and two sliding blocks 21 are withstood on ruler II20 by fastening screw II and are fixed, and then connecting rod 18 is fixed, and incite somebody to action
Round seat 1 is fixed in the lateral direction.As shown in the C in Figure 11.
Three of the above mode can fix round seat 1 in the lateral direction, and then when detail pen 2 draws vertical line by round seat
1 fixes in the lateral direction.And when detail pen 2 draws horizontal line, anterior-posterior translation item 12 is controlled forward due to revolving screw rod 15 by hand
Or slide backward, hand rotation screw rod 15 has the function of screw thread self-locking, so anterior-posterior translation item 12 can also be therewith in front-rear direction
