[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0027] A semi-automatic fastening clamp mechanism is provided, which is located on the rear side of a pump body. A base of a first rotating mechanism is embedded in a mounting groove on the rear side of the pump body. The first rotating mechanism includes a central rotating shaft mounted on the base. A sleeve that can rotate around the central rotating shaft is fitted around the central rotating shaft. A second rotating mechanism is located on the outer side of the sleeve. The rotation plane of the first rotating mechanism is parallel to the rotation plane of the second rotating mechanism. The second rotating mechanism includes a double-ear seat and a fastening clamp located on the outer side of the sleeve. A single-ear seat that matches the double-ear seat is located inside the lower side of the fastening clamp. The double-ear seat and the single-ear seat are hinged together by a limiting pin. The fastening clamp is used to fix the semi-automatic fastening clamp mechanism at the attachment.

[0028] When applying this application, it is installed on the rear side of the syringe pump. The operator needs to adjust the angle between the first and second rotating mechanisms according to the usage, orientation, and the condition of the attached material. This solution allows the syringe pump to be fixed to the attached horizontal or vertical column, increasing the number of application scenarios. The rotating base is fixed to the pump body using bolts passing through the central rotating shaft.

[0029] As per the instruction manual Figure 1 As shown, the first rotating mechanism includes a rotating base, and the housing includes a fastening clamp fixing seat and a washer pressure block. The rear side of the fastening clamp fixing seat and the washer pressure block form a semi-circular rotating fixing mechanism. The fastening clamp fixing seat and the washer pressure block are assembled and fitted onto the raised central rotating shaft on the rotating base.

[0030] As per the instruction manual Figure 1 and7 As shown, a limiting platform is provided at the top of the central shaft. The ring structure formed by the rear side of the fastening clamp and the washer pressure block is a double ring through hole structure from bottom to top. The radius of the ring close to the rotating base is smaller than the radius of the top ring. The double ring through hole interface is adapted to the size of the central shaft.

[0031] The setting of the limiting platform circle ensures that when the sleeve rotates around the rotating base, it only has the freedom of normal rotation, which can prevent the sleeve from detaching.

[0032] A damping washer is installed between the pivot shaft and the housing. The damping washer prevents excessive flexibility between the housing and the rotating base during use, which could affect operation.

[0033] A button is located on one side of the limiting pin after it passes through the double-ear seat and the single-ear seat, and a positioning protrusion is located on the other side. A spring is located on one side of the double-ear seat, and two grooves that match the positioning protrusion are vertically arranged on the other side of the double-ear seat. These two grooves overlap on one side and form a 90° angle on the other side. A locking block is located on the lower side of the single-ear seat in the fastening chuck, and a notch that matches the locking block is located on the lower side of the washer pressure block. The limiting platform circle of the central rotating shaft has two notches, and the two notches of the central rotating shaft are perpendicular to the line connecting their centers. These three notches are identical in shape. A slider is located on the outer surface of the limiting platform circle, and the slider is positioned in the middle of the two notches of the limiting platform circle. An arc-shaped slide is located in the middle of the lower side of the washer pressure block. The width of the arc-shaped slide is adapted to the diameter of the slider, and the length of the arc-shaped slide allows the limiting platform circle to rotate from the first notch facing the locking block to the second notch facing the locking block.

[0034] The operating principle is as follows:

[0035] 1: The fastening clamp fixing seat-03 can be freely suspended from 0 to 90 degrees by relying on the friction generated by the damping washer-02.

[0036] 2: When the fastening clamp base rotates 0 degrees, press button-07. The locking spring-06 is compressed and pushes out the rotation limit pin-05. At this time, the fastening clamp base-03 can be rotated 90 degrees. Release the button-07. The locking spring-06 and the rotation limit pin-05 are reset, so that the head of the rotation limit pin-05 is limited and embedded in the limiting groove of the fastening chuck-08 and the fastening clamp base-03. The fastening chuck-08 is embedded in the limiting groove of the rotating base-01.

[0037] 3: When the fastening clamp base rotates 90 degrees, press button-07. The locking spring-06 is compressed and pushes out the rotation limit pin-05. At this time, the fastening clamp base-03 can be rotated 90 degrees. Release the button-07, and the locking spring-06 and the rotation limit pin-05 will return to their original positions. The head of the rotation limit pin-05 will be limited and embedded in the limiting groove of the fastening chuck-08 and the fastening clamp base-03. The fastening chuck-08 will be embedded in the limiting groove of the rotating base-01.

[0038] The fastening chuck includes a C-shaped chuck and a fixing screw. One side of the C-shaped chuck has a bolt through hole, and the fixing screw has a through-hole for the pipe bolt. A grip is provided on the outer side of the fixing screw. The above is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
