[0052] According to a further improvement of the present invention, the rack and pinion mechanism 26 includes a gear 29 and a rack 30. The gear 29 is coaxially fixed to the bevel gear shaft. The rack 30 is engaged with the gear 29 and is slidably connected to the protective cover 8. The rack 30 is fixed to the movable frame 13.

[0053] A further improvement of the present invention is that the guidewire connecting mechanism 7 includes a support rod 31, a tension sensor 32, and a guidewire holder 33. The support rod 31 is movable through the bracket 3, the tension sensor 32 is fixed to the support rod 31, and there are two guidewire holders 33, one of which is fixed to the bracket 3 and the other is fixed to the support rod 31. The center ends of the two guidewire holders 33 are concentrically arranged with the guide tube 5, so that the guidewire is in a vertical state when straightened.

[0054] The present invention further improves the scheme that the bracket 3 is fixed with a support vertical plate 34, the driving motor 24 is fixed on the support vertical plate 34, and a movable warehouse is provided in the support vertical plate 34, and a gear 2 35 and a rack 2 36 are provided in the movable warehouse, and the gear 2 35 is arranged in the movable warehouse and is rotatably connected with the support vertical plate 34, and the gear 2 35 is coaxially fixedly connected to the motor shaft, and the rack 2 36 is arranged in the movable warehouse and is slidably connected with the support vertical plate 34, and the support vertical plate 34 is provided with a movable groove 37 communicating with the movable warehouse, and the rack 2 is fixed with a connecting frame 38 extending from the movable groove 37, and the connecting frame 38 is fixed to the support rod 31. When the driving motor 24 is started, it drives the motor shaft to rotate, drives the gear 2 35 to rotate, drives the rack 2 36 to move in the vertical direction, drives the connecting frame 38 to move, drives the support rod 31 to move, and then drives the tension sensor 32 to move, and then drives the medical guide wire end to move for tension testing.

[0055] Principle of the present invention:

[0056] When in use, in the vertical direction, there is space for the movable frame 13 to move downward between the two-stage displacement guide wire breakage protection mechanism 4 and the lower end fixture 33. One end of the medical guide wire passes through the lower end of the guide tube 5 from the upper end. The lower end of the medical guide wire is fixed to the guide wire fixture 33 on the bracket 3, and the upper end of the medical guide wire is fixed to the guide wire fixture 33 on the support rod 31.

[0057] After the medical guide wire is fixed, the driving motor 24 is started, driving the motor shaft to rotate, driving the bevel gear 1 27 to rotate, and then driving the two bevel gears 28 to rotate. The rotation directions of the two bevel gears 28 are opposite, driving the two bevel gear shafts to rotate in the opposite direction, and then driving the two gears 1 29 to rotate in the opposite direction. Under the action of the two racks 1 30, the upper and lower moving frames 13 move upward and downward respectively, and then drive the upper and lower corrugated covers 12 to move and unfold. When the moving frame 13 moves, it will drive the corrugated cover 2 14 and the moving frame 2 15 to move in one section. When the moving frame 13 moves, the pull rope 23 is no longer tight. Under the action of the extrusion force of the spring 20, it will drive the moving frame 2 15 and the corrugated cover 2 14 to move in two sections. The corrugated cover 2 14 moves and unfolds, and the medical wire is wrapped by the corrugated cover 1 12, the corrugated cover 2 14 and the protective cover 8 to prevent the broken end from collapsing when it breaks.

[0058] When the drive motor 24 is started, it drives the motor shaft to rotate. The rotation of the motor shaft drives the bevel gear 1 27 to rotate, and at the same time drives the gear 2 35 on the motor shaft to rotate, drives the rack 2 36 to move in the vertical direction, drives the connecting frame 38 to move, drives the support rod 31 to move, and then drives the tension sensor 32 to move, and then drives the medical guide wire end to move for tension testing. When the medical guide wire is in a taut state, through one-stage displacement and two-stage displacement, the corrugated cover 1 12, the corrugated cover 2 14, and the protective cover 8 have wrapped the medical guide wire, avoiding the possible breakage of the medical guide wire and the damage to the operator.

[0059] Although the present invention has been disclosed above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
