The left wound patch body and the right wound patch body are attached to two sides of a wound of a patient respectively, when the wound needs to be sutured, a medical worker controls the occlusion buckle assemblies on the left wound patch to be buckled on the clamping groove buckle assemblies, closing of the skin wound below the left wound patch body and the right wound patch body, suture-free wound is closed, and problems that an existing skin suture method causes secondary trauma to the skin, infection and suture allergy are likely to happen, new scars are left after healing, and pain and inconvenience are caused during suture removal or nail removal.

The invention is suitable for the technical field of machines, and provides a nail removing device. The nail removing device comprises a supporting assembly and a nail removing assembly, the supporting assembly comprises a wood board, a nail cap, a nail body, a support and a strut, the nail cap is fixedly connected to the nail body and located at the upper end of the nail body, the nail body penetrates the wood board, the support is located above the nail body, and the strut is fixedly connected to the support; when nail removal is carried out, an inner ring abuts against the two sides of thenail cap, the inner ring clamps the nail cap at the time, then a grip is pressed down, a connecting rod drives the inner ring to be upwards lifted through an outer ring under the effect of the lever principle at the time, and a nail is taken out from the wood board; and compared with an existing nail removing machine, the novel nail removing device does not need to be inserted into a gap between the nail cap and the wood board in the using process, and the nail removing device is easy and convenient to use and meanwhile saves more force.

The invention discloses a portable stapler capable of detaching staples and using two types of staples. The portable stapler solves the problem of failure to simultaneously bind thick data and thin data in the existing stapler, basically meets the binding requirements of data or books with different thicknesses, and avoids damage to the data when the staples are removed. The portable stapler adopts the technical scheme that the portable stapler comprises a press cover, a staple box and a base, wherein the press cover is hinged to the end part of the base; the middle part of the staple box is rotationally connected with a switching plate of the staple box, and the switching plate of the staple box is connected with the base; the staple box is separated into a first staple area and a secondstaple area, and can be rotated along the switching plate of the staple box, so as to position the first staple area or the second staple area corresponding to the base; a staple removal shear is arranged at the side part of the staple box, and can be rotated at the connecting part with the staple box.

The invention discloses a method of nail-removal chicken feet with pickled pepper, taking frozen chicken feet as the main material and comprising the following preparation steps: thawing and cleaning the frozen chicken feet; roasting skin: roasting the surfaces of the chicken feet with slow fire; removing nails: removing nails manually; tidying: cutting the chicken feet into geometric configuration for standby; cooking, sterilization and elimination of toxicant: boiling by boiling water with the temperature of 100 DEG C; brewing: putting for 10-15 days after the chicken feet are seasoned and improved with aroma; and vacuum packaging. In the method of the invention, the chicken nails are removed after the skin of the chicken feet is roasted; sterilization and disinfection measures of boiling by boiling water are adopted, moderate seasoning and aroma-improving brewing are carried out to ensure that the produced chicken feet with the pickled pepper are cleaner and healthier, and the pickled pepper has more favourable taste; in addition, the produced chicken feet have no obvious chicken skin and nail oily flavour; and the chicken nails can not be seen from the outer package, thereby bringing mental comfort for people and being safe for people to eat.
