Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

As shown in Figures 1 to 4, a fat protection retractor includes a connection assembly and a protective pad 2 installed on a base 1, the connection assembly is a pair of forearms 4 that can be opened and closed by two handles 3 , the handle 3 is provided with a limiter for limiting the opening and closing size of the two forearms 4, the bottom surface of the front end of the forearm 4 is provided with a connecting sleeve 8, and a ring of positioning grooves is arranged side by side in the connecting sleeve 8 The front and the top surface of the base 1 are provided with an insertion slot 9 matched with the connecting sleeve 8, a telescopic rod 10 is arranged in the insertion slot 9, and a pair of telescopic rods 10 are arranged on the outside of the top The positioning protrusion 11 is movably embedded in the positioning groove, and the two protective pads 2 are detachably mounted on the connecting sleeve 8 through the telescopic rod 10 facing outward.

As shown in Figure 1, the shape of the connection assembly is similar to scissors, and the tail ends of the two handles 3 are provided with operation ports that can pass through fingers; the front ends of the handles 3 are connected to the forearm 4, and pins are provided at the connection The shaft 5 and the two handles 3 rotate around the pin shaft 5 to control the opening and closing of the two forearms 4 to adjust the opening and closing of the two protection pads 2 .

The limiter includes a bayonet pin and a clip bar 6, the bayonet pin is arranged on one of the handles 3, one end of the clip bar 6 is hinged on the other handle 3, and the side of the clip bar 6 is provided with Several bayonets 7 that can be embedded in the bayonet.

Wherein, the shape of the clip 6 is arc, so that when the two handles 3 are at different openings, it is convenient to snap the latch 7 into the bayonet; the clip 6 can be hinged to the handle 3 through a universal ball head. to facilitate the operation of the card bar 6.

In one embodiment, the insertion slot 9 is provided with a detachable gasket cover to prevent blood, tissue, etc. from entering the insertion slot 9 .
