[0031] A suction cup 2 is provided at the bottom of the base 1 . The number of the suction cup 2 is one or more, and is used to suck tightly onto the desktop to fix the base 1 .

[0032] The hole seat 3 is located on the upper part of the base 1 and is provided with a positioning hole 4 which is vertically arranged for placing the head cap of the syringe.

[0033] The positioning rubber ring 6 is located in the positioning hole 4, and the positioning rubber ring 6 is used to firmly position the head cap. The positioning rubber ring 6 includes an upper rubber ring 61 and a lower rubber ring 62. The upper rubber ring 61 and the lower rubber ring 62 are respectively used to position the upper middle part and the lower middle part of the head cap to enhance the positioning stability.

[0034] The force-storage lifting mechanism 7 is located in the positioning hole 4, and the positioning rubber ring 6 corresponds to the upper and lower positions of the force-storage lifting mechanism 7. The force-storage lifting mechanism 7 is used to store force when the head cap moves downward, and push the head cap upward through elastic force to achieve the removal of the head cap.

[0035] The force storage lifting mechanism 7 includes a lifting plate 72 and a spring 73 , wherein the top of the spring 73 is connected to the bottom end surface of the lifting plate 72 .

[0036] The hole seat 3 is coaxially arranged with the base 1, and the opening of the positioning hole 4 is specifically located at the middle position of the top of the base 1, which is aesthetically pleasing and convenient for medical staff to place the head cap.

[0037] A guide reamer 5 is provided at the opening of the positioning hole 4. The guide reamer 5 is coaxially arranged with the positioning hole 4. The guide reamer 5 is specifically located at the top of the positioning hole 4 and is outwardly expanded, so as to provide guidance during the insertion of the head cap.

[0038] The upper rubber ring 61 and the lower rubber ring 62 are both located in the annular groove on the inner wall of the positioning hole 4. The annular groove is used to accommodate and position the upper rubber ring 61 and the lower rubber ring 62. The upper rubber ring 61 and the lower rubber ring 62 are both coaxially arranged with the positioning hole 4, and the upper and lower positions of the upper rubber ring 61 and the lower rubber ring 62 correspond to each other, so as to jointly position the same head cap.

[0039] The force-storage lifting mechanism 7 further includes a bottom hole 71 , which is located at the bottom of the positioning hole 4 and is coaxially arranged with the positioning hole 4 . The bottom hole 71 is used to accommodate and place a spring 73 .

[0040] The spring 73 is located in the bottom hole 71, the lifting plate 72 is located at the bottom of the positioning hole 4, and the top of the spring 73 is connected to the lifting plate 72, that is, the lifting plate 72 is connected to the bottom hole 71 through the spring 73. The spring 73 can form elastic force storage during the downward movement of the lifting plate 72.

[0041] The lifting plate 72 is in a disc shape, and the outer diameter of the lifting plate 72 is smaller than the inner diameter of the positioning hole 4 , so as to ensure that the lifting plate 72 can move up and down in the positioning hole 4 .

[0042] An alignment cone 74 is provided on the lifting plate 72. The alignment cone 74 is conical and is specifically located in the middle of the top end surface of the lifting plate 72. The alignment cone 74 is inserted and positioned through the through hole at the end of the head cap, thereby achieving alignment.

[0043] The suction cup 2 is detachably connected to the bottom end surface of the base 1, and the suction cup 2 is specifically a vacuum suction cup. The vacuum suction cup is an existing mature technology, has a good suction and positioning effect, and is low in cost.

[0044] The preferred use skills of the utility model are:

[0045] First, remove the head cap of the syringe from the needle, and then you can perform operations such as liquid medicine aspiration and subcutaneous injection; at this time, the opening of the head cap can be facing upwards and inserted vertically from top to bottom into the positioning hole 4 on the hole seat 3.

[0046] During the insertion process, the guide expansion hole 5 at the top of the positioning hole 4 can guide the bottom of the head cap, and the outer wall of the head cap is tightened by the positioning rubber ring 6. At this time, the bottom end of the head cap contacts the tip of the alignment cone 74 on the lifting plate 72 of the power storage lifting mechanism 7, so that the alignment cone 74 forms a through-type alignment with the through hole at the bottom of the head cap.

[0047] When the use of the syringe is completed, the head cap needs to be put back on the outside of the needle of the syringe.

[0048] At this time, the needle of the syringe is facing downward, aligned with the head cap on the hole seat 3, and the needle is inserted into the head cap from top to bottom; since the suction cup 2 at the bottom of the base 1 is sucked and fixed on the desktop, it does not need to be held in the hand, thus avoiding the needle from pricking the hand.

[0049] When the needle is inserted into the head cap, the head cap presses down the lifting plate 72 of the force-storing lifting mechanism 7 due to the downward axial force during the insertion operation; the lifting plate 72 moves downward under the pressure, and the spring 73 compresses and stores force. When the needle is fully inserted into the head cap, the syringe is moved upward, and the spring 73 applies an upward elastic force toward the lifting plate 72, so that the lifting plate 72 can lift the head cap upward, so that the head cap is separated from the positioning rubber ring 6, thereby facilitating removal.

[0050] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
