Detailed Description

The technical scheme of the utility model is further described below with reference to the attached drawings and specific embodiments.

Example 1

As shown in fig. 1, the novel medical skin preparation knife provided by the utility model comprises a knife body consisting of a knife handle 1 and a knife head assembly 2. The holder 1 includes a hand-held portion 11, and a connecting portion 12 is integrally provided at the tip of the hand-held portion 11. The inside of the connecting part 12 is provided with a clamping component 3 for clamping and fixing the tool bit component 2. The clamping assembly 3 comprises a cavity formed in the connecting part 12, and a sliding plate 31 is slidably connected in the cavity. The top fixedly connected with spring telescopic link 32 of slide 31, and the bottom of slide 31 is provided with reset spring 33 and moves frame group 34, moves the one end fixedly connected with push pedal 35 that frame group 34 kept away from slide 31.

The novel medical skin preparation knife based on the first embodiment adopts the working principle that: when the tool body 1 is in use, a suitable tool bit assembly 2 is selected for assembly. When the tool bit assembly 2 is assembled, the tool bit assembly 2 is directly assembled on the connecting part 12 in the tool handle 1 in a sliding connection mode. When the tool bit assembly 2 is slidably connected to the connecting portion 12, the spring telescopic rod 32 on the clamping assembly 3 in the connecting portion 12 is clamped on the tool bit assembly 2, so that clamping assembly of the tool bit assembly 2 is realized.
