Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Fig. 1-5 are referred to, the utility model provides a kind of technical scheme：A kind of Portable metering chi, including housing 1, button Ring 2, groove 3, protective jacket 4, angle scale 5, binding band 6, velcro 7, protractor 8, pointer 801, threaded post 802, bolt 803rd, abaculus 804, outlet 9, tape measure 10, gear buckle 11, hole 12, magnet 13, Pressing fastener 14 and rotating shaft 15, the upper end peace of housing 1 Equipped with clasp 2, the surface of housing 1 sets fluted 3, and angle scale 5 is inlaid with groove 3, and the side of housing 1 is fixed with protection Set 4, binding band 6 are connected by Pressing fastener 14 with housing 1, and binding band 6 is demountable structure, can be according to actual use demand Installing/dismounting, and material is soft ventilative sponge material, it is higher to be bundled in the comfort level carried on arm or thigh, binding There is velcro 7 with 6 surface inserting, and the bottom of housing 1 is provided with binding band 6, protractor 8 is connected with housing 1, angulation Device 8 includes pointer 801, threaded post 802, bolt 803 and abaculus 804, and threaded post 802, threaded post 802 are provided with pointer 801 Outside be provided with bolt 803, and the top of pointer 801 is provided with bolt 803, and the bottom of threaded post 802 is fixed with abaculus 804, the left and right ends of tape measure 10 are connected to rotating shaft 15 and gear buckles 11, and the inside of housing 1 is provided with rotating shaft 15, housing 1 Lower right be fixed with outlet 9, the cross-sectional area of gear button 11 is more than the cross-sectional area of outlet 9, is not in that gear button 11 enters shell Awkward situation in body 1, hole 12 are connected with rotating shaft 15, and the outside of housing 1 sets hole 12, and threaded post 802 is iron The prism structure of matter six, and the cross-sectional area of threaded post 802 is equal with the cross-sectional area of hole 12, using the shape of prism, uses hand During rotating pointer 801, abaculus 804 and the situation that hole 12 is not in skidding, rotation storage tape measure is relatively stable, hole 12 Inside is provided with magnet 13, and the distance between the lower surface of hole 12 and the upper surface of housing 1 are equal to threaded post 802 on protractor 8 The distance between top surface and the lower surface of abaculus 804, in same level, the space that protractor 8 takes is smaller, and And fixed by the absorption of magnet 13 and abaculus 804, it is allowed to more easily carry out metering work, promotes the steady of measuring ruler industry Development.
