Embodiment
Embodiment
See shown in Fig. 1 to Fig. 7, the scale pin fixed structure of a kind of electronic price computing scale of the present utility model, comprises four of being arranged on bottom upper shell 1 and can be used for the first groove 11 of setscrew nut, identical with the quantity of the first groove four nuts 2 and be arranged in lower shell body 3 and correspond to the open-work 31 of the first groove location; The shape of described first groove 31 and the shape of nut 2 suitable, described nut 2 is positioned in the first corresponding groove 31, and when upper shell 1 and lower shell body 3 fix, nut 2 is pressed in the first groove 11 corresponding to upper shell by lower shell body 3.
First groove of the present embodiment is four, and four the first grooves are located at the corner place of the bottom of upper shell respectively.
Described nut 2 is hexagon, and the cross section of described first groove 11 is set to the hexagon of nut 2 correspondence.
Described upper shell 1 is provided with four the first projections 12 extended to bottom, and described first groove 11 is located at the bottom of the first projection 12.
In described first projection 12, be upwards provided with the first resigning hole 13 by the first groove 11, be used for the screw rod 41 made way on scale pin 4.
Described lower shell body 3 is provided with four the second projections 32 upwards extended, and when upper shell 1 and lower shell body 3 fix, nut 2 is pressed in the first groove 11 of upper shell 1 correspondence by the second projection 32 of lower shell body; Described open-work 31 is located in the second projection 32.
