Composed of a clamping rod, V-shaped clamp, clamping ring and clamping head, this device is engraved with V-shaped grooves in three directions of the clamping head to facilitate the clamping and guiding of injection needles or electrodes. It is used for micro-syringe administration experiments, which can fix both the syringe barrel and the needle at the same time to achieve more stable clamping. The clamping range of the syringe barrel is 3mm-12mm, and the clamping range of the syringe needle is 0.3mm-1.5mm.
