The specific implementation mode is as follows:
the design is illustrated below with reference to the accompanying drawings.
As shown in fig. 1, 2, 3, 4, 5, 6, 7, the ruler for drawing a straight line of the design comprises a marking pen 6, a ruler wheel 3, a rod-shaped handle 1, wherein the front end and the rear end of the handle 1 are both vertically connected with a fork-shaped frame rod 2 downwards, the frame rod 2 is an inverted T-shaped strip which comprises a longitudinal sliding chute, namely a frame rod groove 8, and two transverse sliding chutes, namely connecting rod grooves 17, in a side view state, and the two connecting rod grooves are distributed in a bilateral symmetry manner, as shown in fig. 5 and 6; the handle 1 is also provided with a pressure lever 7 connected with the horizontal brace rod 5 through a vertical notch on the handle, the front end and the rear end of the brace rod 5 respectively extend into a rack rod groove 8 on the front rack rod 2 and the rear rack rod 2 to be connected, and as shown in fig. 3 and 4, the brace rod can be driven to move downwards in the rack rod groove by pressing the operation pressure lever; two groups of identical four-grid parallelogram connecting rod assemblies 10 respectively extend into the fork openings of the front and rear frame rods 2 and are connected to the frame rods at the positions below the frame rod grooves and between the two connecting rod grooves through a middle connecting rod shaft 20 on the connecting rod assemblies, and meanwhile, the left and right connecting rod shafts on the connecting rod assemblies 10, which are close to the middle connecting rod shaft 20, are connected by extending towards the front and rear ends and placing the extending parts of the two connecting rod shafts in the corresponding connecting rod grooves, as shown in fig. 2, 4 and 7; the number of the tape wheels 3 is four, each tape wheel is connected with a pair of flat bar-shaped shaft rods 9 which comprise shaft holes 19 and shaft rod grooves 18 towards one side through the shafts 4, the shaft rods 9 are connected with the outer connecting rod shafts on the connecting rod component 10 through the shaft holes 19 on the shaft rods, meanwhile, the left and the right connecting rod shafts on the connecting rod component close to the middle connecting rod shaft are also arranged in the shaft rod groove 18 on the shaft rod 9 to be connected through the extending parts at the two ends, an extension spring 11 is hung between the left and right connecting rod shafts close to the middle connecting rod shaft on each group of connecting rod assemblies, and can pull each connecting rod of the connecting rod assemblies to contract so that the connecting rod assemblies are in a short length state, as shown in a detail enlarged view of figure 7, thus, the four rule wheels 3, together with the above components and structures, are combined into a straight line drawing rule like a four-wheel car, as shown in fig. 1 and 3; the hand-held handle 1 controls and clings four ruler wheels 3 of the straight ruler to the wall surface of a round rod-shaped object such as a tower-shaped rod 12 and then rolls along the axial direction of the round rod-shaped object, so that the marking pen 6 arranged on the handle 1 can draw a standard longitudinal straight line 13 on the wall surface, i.e. the straight line 13 means that the straight line projection (vertical projection of the straight line) 15 must be a line coinciding with the radial direction on the bottom of the tower-shaped rod (i.e. the circular truncated cone), if the drawn line is not normalized to the arc slope 14, the slope projection (the perpendicular projection of the arc slope) 16 must be an arc line, as shown in figure 8, whereas for a cylindrical rod the so-called normal longitudinal straight line will necessarily be parallel to the axis of this cylinder, namely, the vertical projection of the straight line is a point, and the straight line drawing ruler with four wheels can adapt to the longitudinal line drawing operation of the peripheral wall surfaces of the round rod-shaped objects with various straight wall surfaces and inclined wall surfaces; in addition, since the round bar-shaped object facing the drawing straight line ruler in actual operation is thick and thin, if the distance between the left and right rule wheels on the drawing straight line ruler is small, the drawing straight line ruler cannot be suitable for the line drawing operation of the wall surface of the thick round bar-shaped object, and for the thin round bar-shaped object, the left and right wheel spaces which are wide are also difficult to be suitable for the operation requirement, so that the line drawing device of the design is required to have the function of adjusting the distance between the left and right rule wheels: the pressing rod 7 on the handle 1 is pressed down by a thumb to control the support rod 5 to slide downwards along the rack rod groove 8 on the rack rod 2, so that the support rod 5 contacts with the two middle connecting rods on the connecting rod assembly 10 downwards and supports the two connecting rods towards the left and right sides, the crossing angle between the two connecting rods is increased, the rule wheels at the two ends of each corresponding connecting rod assembly synchronously move and adjust the widening distance towards the left and right sides, as shown in figures 3 and 4, compared with the states of figures 1 and 2, the distance between the left and right rule wheels is widened, the drawing line of the wall surface of a thick round rod object can be adapted, the thumb of the pressing rod is released after the drawing line is finished, the contraction elastic force of the spring 11 can restore the connecting rod assembly to be in a furled state, the distance between the left and right rule wheels is reduced, the two middle connecting rods on the connecting rod assembly 10, which are contacted with the support rod 5, can push the support rod upwards to drive the support rod to, during the reciprocating adjustment change, the left and right link shafts of the link assembly 10 close to the middle link shaft 20 slide horizontally in the link grooves of the hack lever 2 and the link grooves of the link 9 via the extensions at the two ends to coordinate the adjustment change operation. Therefore, after a standard straight line is drawn, an accurate pasting basis is provided, and good conditions are provided for subsequent pasting operation, for example, the zebra pasting can be made very standard without being skewed and inclined, which is an obstacle to looking.
