[0025] Embodiment two:

[0026] As Figures 2-5 shown, the utility model discloses a manual cannula mechanism based on the further improvement of embodiment one, connecting part 3 includes the cooperation of upper assembly sheet 31 and lower assembly sheet 32, clamping part 2 and handle part 1 are installed between upper assembly sheet 31 and lower assembly sheet 32, for making clamping part 2 and handle part 1 form stable support structure through the cooperation connection of upper assembly sheet 31 and lower assembly sheet 32, improve the overall strength and durability of mechanism, avoid the problem of deformation or loosening caused by uneven stress in long-term use.

[0027] The inner surface of upper assembly sheet 31 is provided with mounting shaft 33, and the mounting shaft 33 is multiple, and upper assembly sheet 31 and lower assembly sheet 32 are connected and fixed through mounting shaft 33, and the design of multiple mounting shafts 33 is used to make the connection between upper assembly sheet 31 and lower assembly sheet 32 more firm, can effectively disperse the mechanical stress generated in the operation process, improve the stability and anti-deformation ability of overall structure, in addition, the positioning design of mounting shaft 33 ensures the accurate alignment between upper assembly sheet 31 and lower assembly sheet 32, avoids the deviation that can appear in the assembly process, improves the assembly accuracy and reliability of mechanism.

[0028] Oil pipe interface clamping forceps 4 are provided with oil pipe forceps mouth 41 that cooperate with each other, for clamping the first end of oil pipe.

[0029] The clamping jaw part comprises a fixed arm 52 and a clamping groove 53; the fixed arm 52 is arranged inside the outer surface of the guide pipe 51; the opposite sides of the two fixed arms 52 are provided with matched clamping grooves 53, which are used to ensure that the oil pipe is uniformly clamped during the pipe insertion process, effectively prevent loosening, slipping or deviation caused by uneven force, and improve the stability of the pipe insertion process. At the same time, it can also enhance the clamping force and improve the success rate of pipe insertion.

[0030] The guide rod 6 is fixed with the oil pipe interface clamp 4 through the pipeline of the guide pipe 51, and connects the oil pipe interface clamp 4 and the oil pipe body clamp 5.

[0035] The operating rod 11 and the oil pipe body clamping pliers 5 are hingedly installed on the mounting shaft 33 of the upper assembly piece 31, the top end of the operating rod 11 is movably connected with the end of the guide rod 6, the guide rod 6 connects the oil pipe interface clamping pliers 4 and the oil pipe body clamping pliers 5, and the whole constitutes a transmission rod structure; when the handle part 1 operating rod 11 is opened outward, the guide rod 6 is forced to advance forward, the jaws of the oil pipe interface clamping pliers 4 and the oil pipe body clamping pliers 5 are opened at the same time, and the oil pipe interface clamping pliers 4 moves away from the position of the oil pipe body clamping pliers 5; when the handle part 1 operating rod 11 is closed inward, the guide rod 6 is forced to stretch backward, the jaws of the oil pipe interface clamping pliers 4 and the oil pipe body clamping pliers 5 are closed at the same time, and the oil pipe interface clamping pliers 4 moves to the position close to the oil pipe body clamping pliers 5.

[0036] The use steps of the device are as follows:

[0037] ①Preparation: Ensure that the manual cannulation mechanism is in the initial state, that is, the operating rod 11 is in the closed position, and the jaws of the oil pipe interface clamping pliers 4 and the oil pipe body clamping pliers 5 are closed.

At this time, the guide rod 6 is forced to stretch backward, and the jaws of the oil pipe interface clamping forceps 4 and the oil pipe body clamping forceps 5 are closed synchronously, so that the oil pipe interface can be clamped firmly by the oil pipe interface clamping forceps 4.

[0042] ⑥Positioning the pipe: the hand-operated pipe inserting mechanism for clamping the oil pipe is aligned with the interface of the oil tank oil port, so that the mechanism and the interface of the oil tank oil port are on the same axis, and then the mechanism moves the oil pipe to the interface of the oil tank oil port along the same axis.

[0043] ⑦Completing the pipe insertion: as the mechanism moves gradually, the oil pipe gradually approaches the interface of the oil tank oil port, and finally inserts into the interface of the oil tank oil port. The oil pipe is connected firmly and sealed well with the oil port interface.

Meanwhile, the clamping structure of the oil pipe interface clamping forceps 4 and the oil pipe body clamping forceps 5 is adopted, and the symmetrical guide pipes 51 are arranged on both sides of the oil pipe body clamping forceps 5, so that the stress is uniform during clamping, the oil pipe remains stable during insertion, the situation of loosening or sliding is prevented, and the operation reliability is improved. In addition, the overall design is compact, the occupied space is small, the operation steps are simplified, the pipe insertion can be completed only by the opening and closing action of the handle part 1, and the efficiency of on-site operation is improved.

[0045] Obviously, the above embodiments are only examples for clearly illustrating, and not limit the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted.
