[0045] The trigger head 24 and the lifting sleeve rod 25 adopt the principle similar to umbrella locking technology, and when loosening is needed, only the lifting rod is lifted downward, the traction rod 22 loses the influence of the trigger head 24 in the limit trigger groove 23 and is pulled back to the original position due to the spring 26.

[0046] In the embodiment: the side wall of disassembling ring 11 is also provided with sliding rail 27, and the top of sliding rail 27 is also provided with track limiting clamp block 28, and the track limiting clamp block 28 is provided with square block 29 for corresponding, and the end of square block 29 is provided with adjusting block 291, and the middle of the end of adjusting block 291 is provided with circular hole 292.

[0047] The main purpose of the circular hole 292 and the adjusting block 291 is that the traction rod 22 can be stretched and retracted according to the angle of the roller shaft 121.

[0048] In the embodiment: the top middle of the circular hole 292 is provided with clamping spring 293 for connection, and the bottom of the clamping spring 293 penetrates the square block 29 and is connected with the corresponding trigger head 24.

[0049] There is an additional safety function, that is, the elastic reset potential of the bottom connecting end of the clamping spring 293 is supplemented in some cases.

[0050] In this embodiment: the metal clamp A12 and the metal clamp B13 clamp the insulin needle 294 between them;

[0051] The top end of the insulin needle 294 is provided with the top end of the needle tube 295, and the top end of the needle tube 295 is provided with the pneumatic telescopic rod 296. The end head piston end of the pneumatic telescopic rod 296 pushes the insulin in the needle tube 295.

[0052] The metal clamp A12 and the metal clamp B13 can adjust and pull out the insulin needle 294 according to different clinical needle sizes.

[0053] In this embodiment: the top surface of the disassembling ring 11 is also provided with an arc-shaped supporting mechanism 3, which includes an arc-shaped supporting frame 31 installed on the top end side of the disassembling ring 11. The top end of the arc-shaped supporting frame 31 is provided with a U-shaped arc-shaped push piece 32. The middle part of the U-shaped arc-shaped push piece 32 is adjustably provided with a ball seat 33. The end head of the ball seat 33 is provided with a ball 34 on the surface thereof.

[0054] The purpose of using the ball 34 and the U-shaped arc-shaped push piece 32 is that when the insulin needle tube 295 is rotated, the ball 34 can be sufficiently lubricated to easily disassemble.

[0055] In this embodiment: the end side wall of the disassembling ring 11 is provided with a threaded connection groove. A fastening bolt 14 is transversely installed at the groove end of the threaded connection groove. The end head of the fastening bolt 14 is provided with a connecting gasket 15.

[0056] After the fastening bolt 14 and the connecting gasket 15 are threadedly installed, some ampoule bottle caps are broken by using the principle of a lever.

[0057] In this embodiment: the bottom side of the disassembling ring 11 is provided with a clamping piece 4 for bending the needle by 90 degrees through a rotating shaft. The side wall edge of the clamping piece 4 is also provided with a thumb elastic presser 41 for elastic connection.

[0058] Specifically, in use, first step one: clamping of the insulin needle 294;

[0059] The disassembling ring 11 and the disassembling cavity 111 face the insulin needle 294 (only one of them, with different sizes and specifications of the needle);

[0060] Place it into the disassembling cavity 111. Change the activity range of the metal clamp A12 through the shaft hinging of the roller shaft 121 and the lever 122 until the side wall of the insulin needle 294 is tightly attached. The other side of the needle is clamped with the metal clamp B13.

[0061] Step two: change the interval distance between the clamps;

[0062] Handheld in the pull of the pull rod 22, the telescopic rear control pull seat 21 moves to the right, and the buckle spring 293 is buckled by the elastic force of movement. The elastic sliding stage adjusts one end of the trigger head 24 and the elastic telescopic elastic clamping of the elastic buckle spring 293, and the surface of the trigger head 24 is buckled. The spring 26 is tightened to avoid resetting, driving the metal clamp A12 to clamp the side wall of the insulin needle 294, and the position of the needle tube 295 is attached to the surface of the U-shaped arc-shaped paddle 32. As long as the hand is pinched on the arc-shaped support frame 31, the needle tube 295 is rotated with the ball 34 to achieve damping rotation, and the needle tube 295 is separated after being removed. However, the insulin needle 294 is still clamped by the clamp;

[0063] Step three: loosen the clamp;

[0064] The personnel only need to press the reset spring 297. At this moment, the trigger lifting rod 25 and the trigger head 24 are shortened in position. Then the pull rod 22 is pulled back to the original position by the spring 26 without locking. The metal clamp A12 is opened, and the needle head is automatically dropped;

[0065] Step four: change to a wrench walking position ampoule bottle opener;

[0066] The same method, the difference is that the ampoule bottle is the head in the upper part, which is clamped by the metal clamp A12, and the connecting pad 15 is additionally connected by the fastening bolt 14. The personnel only need to hold the lever of the connecting pad 15 with the force to pry open the ampoule bottle head. In addition, the adjustable metal clamp A12 can cope with some different specifications and sizes of needle heads.

[0067] In addition, in order to facilitate the 90° bending of the needle head, the personnel only need to press the thumb on the position of the thumb elastic presser 41, and then press hard. The clamping piece 4 triggered by the rotating shaft is abutted on the outer wall of the needle to realize the bending.

[0068] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
