The invention discloses a pair of clamping applying pincers for surgical ligation. The clamping applying pincers comprise a tubular shell, a pair of pincers and a magazine, wherein a guide groove is formed in the tubular shell; the magazine is arranged in the guide groove and can move left and right along the guide groove; the pincers comprise an upper pincer opening, a lower pincer opening, an upper pincer opening rotating shaft and a lower pincer opening rotating shaft; the upper pincer opening is fixed to the guide groove through the upper pincer opening rotating shaft and can rotate along the upper pincer opening rotating shaft; the lower pincer opening is fixed to the guide groove through the lower pincer opening rotating shaft and can rotate along the lower pincer opening rotating shaft; the upper pincer opening rotating shaft and the lower pincer opening rotating shaft are respectively arranged on the upper side and the lower side of the magazine; the upper side and the lower side correspond to each other; the upper pincer opening rotating shaft and the lower pincer opening rotating shaft can rotate to the opposite direction when the magazine moves left and right. The clamping applying pincers for surgical ligation provided by the invention are simple in structure and convenient to use, and can clamp and use a ligating clip.

This invention is a garbage bin lid, comprising of a lid frame, a lid, a lid open-and-close units and a joining unit. One end of the lid and the lid frame are joined and positioned by a lid open-and-close unit that controls the opening and closing of the lid. The other end of the lid and lid frame has a joining unit in which there is a spring that can push the lid up. By pressing the lid open-and-close unit, the lid will unclip and spring up. When closing the lid, it is necessary to push the lid down to the lid open-and-close unit on the lid frame then it will clip into place and close.

The sealed superthin food container includes a box cover and a box body. The box cover has downward opened ring slot comprising inner slot wall, slot top and outer slot wall in the edge; and the box body has complex edge comprising inner straight edge, flat edge and outer straight edge. After the ring slot is fitted with the complex edge, one inner sealing part and one outer sealing part are formed. The slot has also protuberant blocks for locking the outer straight edge to form the separation preventing part. Therefore, the box cover may be covered to the box body to form a sealed structure with high sealing performance and high compression strength to avoid food soup leakage, and the box cover will not separate from the box body while the flexible box is extruded.

The present invention relates to a pressure oven with a pressurized inner container. The pressure oven includes an oven body, the inner container, an oven door and a handle, where the bottom side of the oven door is rotatably connected with the oven body, the handle is provided on top of the oven door, two locking catches are horizontally provided on the front face of the oven body, the corresponding inner surface of the oven door is provided with two locking hooks, and the handle drives the two locking hooks to rotate via a linkage drive device so as to achieve locking or unlocking between the locking hooks and the locking catches. The pressure oven has a rational structural design, the oven door is convenient for opening and closing, and a pressure relief valve is designed to be on the oven door so as to help combine the oven as an integral part of the entire kitchen. In addition, heating electronic elements are located at the back faces of the oven door and the oven body, such that two side faces of the oven body do not have a heating element. The heating element in the oven door is cooled by a cooling fan, the heat from the heating element at the back face of the oven body is dissipated via heat dissipation holes, such that no heat dissipation hole is needed on the two side faces of the oven body. The oven has an attractive appearance, the inner container is an integral body with a high tensile strength, has no gap, and is easy to clean. The pressure oven can be secured by a hanging hook and can be easily dismounted.

The invention discloses a concealed socket capable of rolling towards multi-directions, which comprises a body, a pivoting part, a holding part, and at least one jack group. At least one jack group is arranged on the body; the holding part is used for holding the body; the pivoting part is pivoted with the body, and comprises a first rotating shaft, and a second rotating shaft; the first rotating shaft leads the body pivoted on the first rotating shaft to rotate along the axis direction of the first rotating shaft through the drive of the first rotating shaft; the second rotating shaft is pivoted with the holding part and the first rotating shaft; moreover, the axis direction of the second rotating shaft and the axis direction of the first rotating shaft are mutually vertical; and the first rotating shaft rotates along the axis direction of the second rotating shaft through the drive of the second rotating shaft; therefore, the body is driven by the rotation of the first rotating shaft and the second rotating shaft, can combine the rotations on two directions, and is beneficial for the reversing as well as opening and closing motions of the concealed socket to lead the concealed socket to reach concealed holding effect.

The invention relates to an automatic zipper head which comprises a pull head body, a pull piece, a hook, a straight elastic piece and a cap which are sequentially arranged from bottom to top. Two ends of the hook are both embedded in the pull head body, a containing space is formed by the hook and the pull head body to contain the end portion of the pull piece, two ends of the cap are mechanically connected with the pull head body, two ends of the straight elastic piece are mechanically connected on the inner wall of the cap, and the middle of the straight elastic piece is adjacently connected with the hook. The automatic zipper head has the advantages of being simple and convenient to operate, convenient to assemble and the like.

The invention relates to a fuel cell hydrogen recovery device. The fuel cell hydrogen recovery device comprises a fuel cell, a controller, a hydrogen recovery pipe provided with a hydrogen circulatingpump and a stop valve, an air inlet pipe connected with the fuel cell, an air exhaust pipe connected with the fuel cell, a hydrogen inlet pipe provided with a hydrogen inlet valve and a hydrogen exhaust pipe provided with a exhaust outlet valve, and the hydrogen recovery pipe is connected with the hydrogen inlet pipe. The fuel cell hydrogen recovery device is characterized in that the fuel cell hydrogen recovery device further comprises an integrated type gas-liquid separation storage tank, an gas-liquid separation storage tank is integrally formed by a storage tank on the upper part and a gas-liquid separation separator on the lower part, the storage tank is correspondingly connected with the hydrogen exhaust pipe and the hydrogen recovery pipe, and the gas-liquid separation separator discharges waste water and redundant nitrogen through a waste discharging pipe provided with a waste discharging valve. Compared with the prior art, the fuel cell hydrogen recovery device has the advantages of exhaust gas buffering, effective cooling, uniform and safe exhaust, noninterference of discharging liquid water and hydrogen and the like.
