New description: [New technical field] This creation is a technical field related to compasses, especially a compass improvement I ° [Previous technique] The used compass mainly consists of a compass head, a support foot and a rounded foot, one end of the support leg and one end of the rounded foot are pivotally connected to the compass head, and the other end of the rounded foot ^ is fixed with a chalk, and the user abuts the support foot The blackboard can be used as a fulcrum, and the circular stroke can be performed through the rounded foot. However, the conventional compass structure can only be used on the blackboard alone, and the function is quite limited, which cannot effectively meet the needs of the current modern people. The problem is really necessary for improvement. [New content] The technical problem to be solved: the conventional compass mainly includes a compass head, a supporting leg and a rounded foot, and the end of the supporting leg and the end of the rounded foot are connected to the compass On the head, the other end of the rounded foot is fixed with a piece of chalk. The user can press the support foot against the blackboard, and the support foot can be used as a fulcrum to perform a circular cutting operation through the lining. It is only on the blackboard, and the functions are quite limited, which can not effectively meet the needs of the current modern people. Technical features for solving the problem: providing a modified compass structure, comprising: a compass head, a support rod, a round rod, a first pen body and a second pen body. The compass head includes a pivoting portion and a “limit block”; the read lever includes a first pivoting structure and a stop slider, and the first pivoting structure is located at one end of the support rod. The slider is located at the other end of the cutting rod, and the support rod is pivotally connected to the pivoting portion of the compass head through the first frame 3 M363398. The rounding rod includes an n-connection structure and a pivot The dual-purpose structure includes: a first fixing portion and a first W-axis, wherein the second pivoting structure is located at an end of the closed-rod, the frame-transferring structure is pivotally positioned The other end of the coffee bar is pivotally connected to the pivoting portion of the compass head through the second splicing structure. The first pen system is fixed on the first fixing portion. The two-pronged system is fixed on the second fixing portion, and the stopping slider of the supporting rod is used as a fulcrum, and the rounding rod can perform a circular motion through the first pen body or the second pen body. / wherein the round bar further includes a -th pole portion and a second pole portion, the first pole portion, the second pole portion being symmetrically disposed in parallel with each other, the end of the first stem portion and the ^ One end of the two rod portions is pivotally connected to the pivoting dual-purpose structure. And / wherein the first fixing portion can be a taper pressing device. Wherein, the first pen system is - chalk "the chalk system is forced to taper with the cone. The second fixing portion may be a screw locking device. The whiteboard pen is tied to the screw lock. The second pen system is a whiteboard pen, and the device is screwed tightly. Wherein the first solid portion and the second fixed portion intersect at a right angle. Compared with the effect of the prior art: the creation of the leaf by the insertion and rotation structure can make the - a compass have the circular function of different pens at the same time, for example, can be combined with chalk and whiteboard pen cutting. In the case of snow 1 , the L ^ t疋 needs to enter the (4) circle on the blackboard to pivotally position a piece of chalk through the pivoting dual-purpose structure. If it is necessary to perform a rounding on the whiteboard, the pivoting structure can be pivoted through the pivoting structure. Positioning—Whiteboard pen, use the upper heart ^ Tian Erli 1丨 _ Tian Zhe preferred embodiment of the technology, means and functions used in this creation, M363398, structure and its special cooperation with the detailed description of the following I believe that the above-mentioned purpose of this creation can be obtained from an in-depth and specific understanding.
