[0041] Optionally, the connecting handle sleeve 220 is a conical structure, and the connecting handle sleeve 220 is made of plastic material. The insertion portion sleeve 210 and the connecting handle sleeve 220 can be connected by welding.

[0042] For further information, please refer to Figure 4 The connecting handle sleeve 220 is provided with a limit block 230, and the limit block 230 is provided with a through hole 231 for the piercing portion 110 to pass through. The limit block 230 is used to limit the piercing position of the piercing portion 110 through the through hole 231. The size of the through hole 231 matches the outer diameter of the piercing portion 110.

[0043] In this embodiment, the limit block 230 can be welded or integrally formed with the connecting handle sleeve 220. A through hole 231 is set at the center of the limit block 230. When the insertion part 110 passes through the through hole 231, passes through the connecting handle sleeve 220, and enters the insertion part sleeve 210, the limit block 230 can fix, position and limit the insertion part 110, prevent the insertion part 110 from shaking when passing through the insertion part sleeve 210, and further improve the stability of the sleeve 200.

[0044] During installation, the limit block 230 contacts and abuts against one end of the connecting rod portion 120, and then the holding portion 300 is sleeved outside the connecting rod portion 120, so that one end of the holding portion 300 abuts against the connecting handle sleeve 220, and then the connecting handle sleeve 220 and the holding portion 300 are fixed by superconducting welding.

[0045] For further information, please refer to Figure 6 The syringe 1 further includes: a pressing operation part 400, the connecting rod part 120 is provided with a groove 121, and the pressing operation part 400 is installed in the groove 121. Please refer to Figure 5, the grip part 300 is provided with an opening 310, and the pressing operation part 400 passes through the opening 310 and can move in the opening 310.

[0046] The gripping portion 300 protects the connecting rod portion 120. Optionally, a gripping surface may be provided on the outer surface of the gripping portion 300 to facilitate gripping and fixed installation of the gripping portion 300.

[0047] Optional, see Figure 2 , Figure 6 The pressing operation part 400 includes: a fixing part 410 and a pressing part 420, the fixing part 410 is connected to the pressing part 420, the fixing part 410 is provided with a slot 411 matching the groove 121, the slot 411 of the fixing part 410 is engaged in the groove 121, and the pressing part 420 passes through the opening 310 and moves in the opening 310.

[0048] In this embodiment, please refer to Figure 7An arc-shaped slot 411 is provided on the fixing portion 410, and the shape of the arc-shaped slot 411 matches the shape of the groove 121 on the connecting rod portion 120. With such a configuration, when the fixing portion 410 is installed on the connecting rod portion 120, the slot 411 can be engaged in the groove 121, so that the fixing portion 410 is connected and fixed to the connecting rod portion 120.

[0049] In other embodiments, the fixing portion 410 may also be directly sleeved in the groove 121 of the connecting rod portion 120 , so that the fixing portion 410 is fixedly connected to the connecting rod portion 120 .

[0050] Since the pressing portion 420 can be moved forward and backward by the operator within a relatively small range of the opening 310, when the operator moves the pressing portion 420, the fixing portion 410 and the connecting rod portion 120 move backward in the gripping portion 300 to achieve the retraction of the piercing portion 110, the sleeve 200 can be installed and inserted into the main body 100. Specifically, the piercing portion 110 is inserted through the through hole 231 of the limit block 230 on the connecting handle sleeve 220, so that the piercing portion sleeve 210 is sleeved outside the piercing portion 110. At the same time, the connecting handle sleeve 220 and the gripping portion 300 are fixed by superconducting welding.

[0051] After the sleeve 200 is installed in place, the operator moves the pressing portion 420 to drive the fixing portion 410 and the connecting rod portion 120 to move forward in the gripping portion 300, and pushes the piercing portion 110 forward.

[0052] Therefore, the piercing portion 110 can be pushed out and retracted by operating the pressing operation portion 400 , thereby achieving leakage and covering of the piercing portion 110 , and further allowing the sleeve 200 to effectively protect the piercing portion 110 .

[0053] Further, to prevent the pressing portion 420 from moving in the opening 310 after being pushed forward or backward, please refer to Figure 5 The grip portion 300 is provided with a first blocking portion 320 and a second blocking portion 330 , and the opening 310 is an opening formed by a downward depression on the grip portion 300 . The first blocking portion 320 and the second blocking portion 330 are both portions that protrude upward relative to the opening 310 formed by the downward depression.

[0054] When the operator operates the toggle pressing portion 420 to drive the fixing portion 410 and the connecting rod portion 120 to move forward in the grip portion 300 so as to push the piercing portion 110 forward, the pressing portion 420 will not move forward due to the restriction of the first blocking portion 320; similarly, when the operator operates the toggle pressing portion 420 to drive the fixing portion 410 and the connecting rod portion 120 to move backward in the grip portion 300 so as to retract the piercing portion 110 backward, the restriction of the second blocking portion 330 prevents the pressing portion 420 from moving backward.

[0055] The syringe 1 of the present application can effectively protect the piercing portion 110 of the syringe 1 by providing the sleeve 200. The grip portion 300 is integrally formed with a simple structure and is easy to install. The piercing portion 110 of the present application can be replaced in time according to surgical needs.

[0056] Secondly, in the present application, the insertion portion 110 can be pushed out and retracted by operating the pressing operation portion 400, thereby achieving leakage and covering of the insertion portion 110, and the sleeve 200 can effectively protect the insertion portion 110.
