Description

Technical Field

[0001] This utility model belongs to the field of veterinary syringe technology, specifically relating to a multi-purpose injection device with a gear adjustment structure. Background Technology

[0002] A semi-automatic continuous injection gun is a veterinary injection device primarily used for animal vaccination and drug injection. The key feature of this type of injection is that the maximum dosage for each injection can be pre-set via an adjustment dial, and then the handle is pulled to administer the injection. The amount of medication injected each time is fixed.

[0003] However, most commonly used semi-automatic gun-type continuous injectors currently employ a continuously variable adjustment disc, meaning the angle of the adjustment disc is not fixed each time it is turned. Furthermore, the continuously variable adjustment will fluctuate slightly during use, and the dosage will vary with repeated use. Therefore, the precision of each adjustment in this type of semi-automatic gun-type continuous injector is relatively poor.

[0004] To address the aforementioned problems, this invention aims to provide a multi-purpose injection device with a gear adjustment structure. This structure ensures that adjustments can be made according to the gear position when adjusting the adjustment dial, allowing for quantification of the adjustment angle with each adjustment. Furthermore, the fixed scale for each adjustment guarantees consistent accuracy. Utility Model Content
