At this time, if the user attempts to continue The operating member 2g is pushed forward. Since the front stop concave surface 221 has a concave curvature, the front support 7 M382133: the surface 221 will be closer to each other than the first blocking portion 15 (four), and further narrowed down. The width of the front communication & 143, thus, prevents the operating member 2 from slipping forward out of the protection kit 10; then, as shown in Figures u and 12: the user can The butterfly sheets 12 are folded inwardly to the folded state, so that the click recesses 121 of the butterfly discs 12 and the rear concave concave surfaces of the pushing portions 23 are snapped into each other, so that the operating member 20 cannot be retracted. When the rear bump Φ 231 has a concave curvature, the rear stop concave s 231 can temporarily catch the butterfly discs 12 to prevent the butterfly discs 12 from being related to material properties. Bounce back to the unfolded state (see Fig. 5), so that when the user pinches the butterfly discs 12, the operating member 2 can be placed between the first stoppers 15 (see Fig. 10). Between the butterfly discs 12 and the first position, the process of preventing the operating member 2 from slipping is prevented from slipping relative to the protection kit 10. Then, as shown in FIGS. 13 and 14, after the application is completed, the user can push the operating member 20 rearward to the third position, in the process, since the rear end width of the temporary limiting portion 144 becomes smaller. And the introduction slope is formed. Therefore, the trailing slope 222 of the slider portion 22 can smoothly guide the slider portion 22 through the rear communication portion 146 to enter the accommodating portion 145 when in the third position. The front stop concave surface 221 of the slider portion 22 is in contact with the second stop portion 17, and the slider portion 22 can be positioned on the receiving portion 145, so that the operating member 2 is located at the third portion. Position, at this time, the needle is located in the passage 13; thereafter, if the user attempts to push the operating member 2 forward again, since the front stop concave surface 221 has a concave curvature, the front stop concave surface 22i will drive the second blocking portions 17 toward each other inwardly, and further reduce the width of the rear connecting portion 146 by 8 M382133. Thus, the slider portion n can be prevented from sliding forwardly out of the receiving portion 145. And achieve the purpose of a disposable use. It is worth mentioning that the assembly process of the present invention is as follows: 1. The tube 40 is passed forward through the passage 13 of the protection kit 10. 2. The tube 4G is sleeved with the rod portion 21 of the operating member 2G. 3. Aligning the slider portion 22 of the operating member 20 with the front lead-in section (4), 'push the rod portion 21 rearwardly toward the channel 13, in the process, the back end width of the front lead-in section (4) becomes smaller. The introduction slope is formed, so that the rear guide slope 222 of the slider portion 22 can smoothly guide the slider portion 22 through the front introduction portion 141 and slide backward into the guide portion 142. The operating member 20 is pushed forward to the second position, and the needle 30 is fixed to the stem portion 21 of the operating member 2''. 5. Push the operating member 20 rearward to the first position. Through the above description, the advantages of the present invention can be further summarized as follows. 1. When the present invention is to be applied, the latter can pinch the butterfly discs 12 so that the operating member 20 is limited to the first- The shutter portion 12 is blocked. Between the two positions, the new money is effectively prevented from slipping relative to the protection kit 1 in the process of pinning. 2. After the present invention is applied, the surface (2) of the slider portion 22 of the Lee (4) abuts against the second stopper portion 17, so that the slider portion is located in the valley portion 145, thereby making the operating member 2〇 Positioned in the first, so 'this new wealth effective anti-cutting piece 2Q once again set to 145' to achieve the purpose of the - disposable use. When the operating member 20 of the present invention is in the second position, the front stop concave surface 221 of the slider portion 2 can abut against the first stopping portions 15 to prevent the / member 20 from facing Front slide out of the protection kit 〇. 4. When the operating member 20 is in the second position and the butterfly sheets 12 are folded inwardly to the folded state, the rear stop concave surface 231 of the pushing portion 23 can temporarily buckle the butterfly discs 12, Therefore, the new ^ can prevent the butterfly discs 12 from automatically rebounding to the unfolded state. 5. Since the wrinkle grooves 123 of the butterfly sheets 12 contribute to the bending deformation of the butterfly sheets 12 adjacent to the protective cover 1 (), the butterfly sheets 12 are in the folded state, two The gap between the four (4) gaps can be effectively reduced so that the card recesses 121 of the butterfly discs 12 are effectively engaged with the rear stop concave surface 231 of the pushing portion 23. In summary, the infusion type safety needle of the present invention, Not only is it safe to use, but it also has the function of disposable use, so it can achieve the purpose of this new type. 7 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 ^ are still within the scope of this new patent. 10 M382133 [Simplified illustration of the drawings] Fig. 1 is a schematic cross-sectional view of a conventional disposable safety needle; Fig. 2 is an exploded perspective view of a conventional safety butterfly needle structure; Figure 3 is a top plan view of a protection kit of the preferred embodiment; Figure 5 is a bottom perspective view of the protection kit; Figure 6 is a perspective view of the preferred embodiment of the present invention; Figure 7 is a cross-sectional view of the preferred embodiment illustrating the operating member in a first position; Figure 8 is a cross-sectional view of the \i_vm cut line in Figure 7; Figure 9 is a similar Figure 7 is a cross-sectional view showing the X-X cut surface line of Figure 9; Figure 10 is a front elevational view of the preferred embodiment of the preferred embodiment, illustrating the operation member The second position 'and the two butterfly sheets of the protection kit are bent inwardly to a folded state; FIG. 12 is a side view of FIG. 11; FIG. 13 is a view similar to FIG.
