[0031] The adjusting mechanism 3 is located inside the guide body 1. The adjusting mechanism 3 adjusts the angle of the guide bracket 2 to facilitate fixing the puncture angle into the skin and determine the skin penetration depth through the puncture angle.

[0032] When the utility model is in use, the guide body 1 is placed above the skin to be punctured, and the puncture angle can be adjusted according to the puncture depth. The guide body 1 can be slid inside by pressing the buttons 47 at both ends. When it slides to the required position, the buttons 47 can be released to fix it. Not only can the puncture angle be adjusted, but it is also very convenient to use.

[0033] The adjustment mechanism 3 includes a guide bracket 2 arranged above the guide body 1, the guide bracket 2 is rotatably connected to the guide body 1, an adjustment slot 31 is provided above the guide body 1, a plurality of clamping blocks 32 are fixedly connected to the bottom of the adjustment slot 31, the clamping blocks 32 are arranged equidistantly, an adjustment member 4 for adjusting the angle of the guide bracket 2 is provided above the clamping block 32, the adjustment member 4 includes a slide bar 41 slidably connected above the clamping block 32, slide slots 42 are provided at both ends of the guide body 1, the slide bar 41 is located in the slide slot 42 and is slidably connected to the slide slot 42, a torsion spring 43 is fixedly connected to the outer wall of the slide bar 41, and the torsion spring 43 is fixedly connected to the end away from the slide bar 41 There is a pawl 44, which is rotatably connected to the slide bar 41. The pawl 44 is located above the clamping block 32 and is clamped with the clamping block 32. A protective shell 45 is provided above the pawl 44, and the protective shell 45 is fixedly connected to the guide body 1. Springs 46 are fixedly connected at both ends of the slide bar 41, and a button 47 is fixedly connected to the end of the spring 46 away from the slide bar 41. The button 47 is located on the periphery of the slide bar 41 and is slidably connected to the slide bar 41.
