[0003] Generally speaking, after the extension tube is installed, the operation of the blood collection needle will be more convenient. Because of its advantages of being far away from the puncture point and easy to replace the test tube, the application of the blood collection needle with a flexible extension tube is more common, but the delivery, interception, and fixation of the extension tube , transfer and other aspects become more difficult

The invention discloses a cutting-off mechanism. The cutting-off mechanism comprises a clamping assembly and a cutter assembly. The clamping assembly is composed of a first clamping jaw and a second clamping jaw which can pivot around a first pivotal axis and are hinged to each other. Flexible clamping heads are used as clamping heads of the first clamping jaw and the second clamping jaw correspondingly. The cutter assembly comprises a cutter arm and a cutter edge which is located at the front end of the cutter arm and used for cutting hoses off. The tail end of the cutter arm is rotationallyarranged on a third pivotal axis of the first clamping jaw. The second clamping jaw is provided with a fourth pivotal axis. The cutter arm is provided with a kidney-shaped sliding groove matched withthe fourth pivotal axis of the second clamping jaw. A power of the second clamping jaw to the cutter arm is shorter than a resisting arm of the cutter arm to the second clamping jaw, and thus the cutter edge at the front end of the cutter arm can synchronously cut clamped objects off when the second clamping jaw and the first clamping jaw are driven to clamp the objects tightly. The invention further provides a hose winding device using the cutting-off mechanism and blood taking needle assembling equipment using the cutting-off mechanism.
Description
technical field [0001] The present application relates to the technical field of medical device production equipment, in particular to a hose winding device and a cutting mechanism for assembling a blood collection needle. [0002] In addition, the present application also provides a blood collection needle assembly device using the above hose winding device. Background technique [0003] Generally speaking, after the extension tube is installed, the operation of the blood collection needle will be more convenient. Because of its advantages of being far away from the puncture point and easy to replace the test tube, the application of the blood collection needle with a flexible extension tube is more common, but the delivery, interception, and fixation of the extension tube , Transfer and other aspects are more difficult. During the manufacturing and assembly process, the extension tube needs to be wound to facilitate the assembly of the blood collection needle assembly. ...
