Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
It should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are intended to be construed broadly, as if they were connected either fixedly or removably, or as integrally formed structures. To those of ordinary skill in the art, the specific meaning of such terms in this patent may be understood as appropriate.
As shown in fig. 1-3, the fixing device for processing a medical injector needle according to the present invention comprises a fixing base 1 and a fixing splint 2; the fixed seat 1 is provided with a motor 4; a plurality of arc-shaped grooves 21 are formed in the fixed clamping plate 2. A movable clamping plate 3, a screw 6 and a plurality of limiting rods 5 are arranged between the fixed seat 1 and the fixed clamping plate 2. The movable clamping plate 3 is provided with a limiting through hole 33; the limiting rod 5 penetrates through the limiting through hole 33, and two ends of the limiting rod are fixedly connected with the fixing seat 1 and the fixing clamp plate 2 respectively. The screw rod 6 is in threaded connection with the movable clamping plate 3, one end of the screw rod is fixedly connected with the output end of the motor 4, and the other end of the screw rod is rotatably connected with the fixed clamping plate 2.
The limiting rod 5 has the functions of limiting and guiding the movable clamping plate 3, namely, the movable clamping plate 3 is limited to move only along the axial direction of the screw 6. The screw rod 6 is driven to rotate by the motor 4, and the screw rod 6 drives the movable clamping plate 3 to move along the axis direction of the screw rod 6, so that the position of the movable clamping plate 3 is controlled, and the needle head is clamped or loosened. Because the clamping distance can be flexibly adjusted, the fixing device is suitable for medical syringe needles with different diameters, and the clamping stability is good.
