First fixed axle is spacing to be led to the inslot in the arc on the one hand can restrict the opening home range of two protractors, and on the other hand can promote the stability of connecting between two protractors.
In this embodiment, the two angle gauges are respectively provided with a second arc-shaped through groove 4 which takes the hinge point as a circle center and has the same radius, the radius of the second arc-shaped through groove is 10mm, the second fixing shaft 41 passes through the two second arc-shaped through grooves and is fixed with the upper clamping plate and the lower clamping plate where the clamping portion is located, and the second fixing shaft is located on the symmetry axis where the hinge point is located and is relatively fixed with the hinge point and the first fixing shaft. And the two second arc-shaped through grooves are respectively provided with a return spring 42, one end of each return spring is respectively fixed on the second fixing shaft, and the other end of each return spring is respectively arranged at one end of the corresponding second arc-shaped through groove far away from the second fixing shaft. When the open angle slowly opens, the sector of two angle scales moves towards the symmetry axis position direction at pin joint place respectively, and at this moment first arc through groove and second arc through groove move along first fixed axle and second fixed axle direction respectively to reset spring in the second arc through groove can be compressed along with the removal in second arc through groove. However, since the maximum stroke of the first arc-shaped through groove can limit the maximum opening angle of the opening to 190 degrees, and the compression stroke of the spring is controlled within the elastic limit, the spring can be prevented from being excessively compressed to cause elastic deformation. When the measurement is finished, the angle measuring ruler is reset under the elastic force of the reset spring and is restored to the initial state.
In this embodiment, be provided with gasket 5 on the measuring foot of two measuring rulers respectively, the thickness of gasket can equal with the thickness of measuring ruler, the shape of gasket and the shape looks adaptation of measuring foot, the gasket is crisscross the setting respectively on the measuring foot of the open position that two measuring rulers correspond to through the fix with screw on the measuring angle, make the both ends face looks parallel and level of the measuring foot that the open position corresponds. Preferably, the two end faces of the measuring angle and the two end faces of the holding part can be aligned by increasing the thickness and the number of the gaskets. Therefore, when the measuring feet of the angle measuring ruler are abutted against the breast angle position of the poultry, the two end faces of the opening can be kept on the same plane, and the measuring result is more accurate.
In this embodiment, the hinge point, the first fixing shaft and the second fixing shaft of the two angle scales are projected in one direction and located on the same straight line, and the same straight line is a position of a symmetry axis between horizontal projection planes when planes in which the two angle scales are stacked on each other are placed on a horizontal plane.
In summary, the poultry breast angle gauge provided by the invention can form an opening for abutting against the poultry breast angle position together with the mutually hinged angle gauges for measuring the poultry breast muscle development condition. However, because the hinge point of the traditional thoraco-angle device is close to the opening position formed by the two angle scales, the position far away from the hinge point between the two angle scales is easy to generate the condition of offset after long-term use, and then the overall connection stability of the thoraco-angle device is influenced. Therefore, the first fixing shaft and the first arc-shaped through groove are further arranged on the two angle measuring rulers which are hinged with each other, so that the first fixing shaft penetrates through the two first arc-shaped through grooves and is fixed relative to the hinge point. And then avoid producing the skew between two articulated protractors, further promoted the connection stability between two articulated protractors each other.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
