DETAILED DESCRIPTION

[0014] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0015] See Figure 1 —— Figure 3 As shown, this specific embodiment adopts the following technical scheme: it comprises an electronic ruler 1, an electronic ruler transition plate 2, an electronic ruler seat plate 3, a blow needle bracket 4, a blow needle seat plate 5, a guide rod 7, a connecting seat 8, a blow needle 9, a guide rod mounting seat 10, a blow needle mounting seat 11 and a blow needle cylinder 14; a connecting seat 8 is installed between the blow needle seat plate 5 and the blow needle bracket 4, a blow needle cylinder 14 is installed on the blow needle bracket 4, an electronic ruler transition plate 2 is installed on the blow needle seat plate 5, the electronic ruler 1 is fixedly connected to the blow needle bracket 4 through the electronic ruler seat plate 3, the electronic ruler 1 is vertically connected to the electronic ruler transition plate 2, a blow needle mounting seat 11 is fixed to the bottom of the blow needle seat plate 5, and the upper end of the blow needle 9 is installed on the blow needle mounting seat 14. On the mounting seat 11, the lower end of the blow needle 9 is inserted into the guide rod mounting seat 10, a guide rod 7 is installed between the guide rod mounting seat 10 and the blow needle bracket 4, the blow needle seat plate 5 is slidably connected to the guide rod 7, the upper end of the guide rod 7 is fixed to the blow needle bracket 4 through a pressing plate 17, a support plate 6 is fixed to the guide rod 7, a guide rail 15 is installed on the support plate 6, and two upper and lower induction switches 16 are installed on the guide rail 15 by screws.
