The invention relates to a blood sampling pen convenient for unloading pricking cap. The blood sampling pen comprises a shell, a shooting rod and a needle unloading rod, and is characterized in that an elastic lug and a blocking surface are arranged between sliding matching surfaces of the needle unloading rod and the shooting rod, wherein the elastic lug is arranged on one sliding matching surface, the blocking surface is arranged on the other sliding matching surface, and the elastic lug and the blocking surface are positioned on a same sliding path. In a needle unloading state, as the needle unloading rod moves forwards relative to the shooting rod, the elastic lug and the blocking surface move towards each other; and when the distance between the elastic lug and the blocking surface iszero on the sliding path, interference is generated, the needle unloading rod forced to move forwards relative to the shooting rod is stopped, a blood sampling needle moves forwards away from the original position in a needle seat, and the needle tip of the blood sampling needle is exposed from a blood sampling end face so as to facilitate cap pricking. The scheme solves the problem that the prior cap unloading-free blood sampling pen is inconvenient to operate due to the fact that the prior cap unloading-free blood sampling pen has no stopping of cap pricking and observation of the needle tip is limited when the needle is unloaded.

The invention relates to a blood sampling pen capable of preventing mistakenly operated needle unloading after loading. The blood sampling pen comprises a shell, a shooting rod and a needle unloadingrod, and is characterized in that an elastic arm specially used for needle unloading protection is designed on the shooting rod, a main trigger part is arranged on the arm of the elastic arm, and thearm end of the elastic arm is used as a bolt. Meanwhile, the main trigger part is provided with an auxiliary trigger part arranged on the shell, and aiming at the bolt, a lock opening is arranged on the needle unloading rod.

The invention relates to an embroidery method of a knotting embroidery with different colors of two surfaces. The method is characterized in that aiming at patterns which form mirror images mutually on the front and back surfaces of a same embroidery backing material, two sets of needles and threads are utilized, and a knotting embroidery stitching method is adopted to carry out embroidery on the front and back surfaces of the backing material at the same time. One set of needle and thread is used for knotting on the front surface and the needle is hidden on the back surface; and the other set of needle and thread is used for knotting on the back surface and the needle is hidden on the front surface. The operation of knotting on the front surface and the operation of knotting on the back surface are alternately performed in a one to one mode, and needle hiding is alternately performed relative to the knotting operation. The positions of knotting on the front and back surfaces are the same, and the stitch lengths are consistent. The first embroidery thread forms the knotting pattern on the front surface, and the second embroidery thread forms the knotting pattern on the back surface, wherein stitches left on the back surface by the first embroidery thread are hidden behind the knotting pattern on the back surface, and stitches left on the front surface by the second embroidery thread are hidden behind the knotting pattern on the front surface. As the front surface and the back surface are simultaneously subjected to equal and synchronous embroidering operation, a knotting embroidery work with different colors of two surfaces and the same effect can be obtained.
