The invention discloses a folding knife locking structure. The locking structure comprises a lock bridge, a button gasket, a screw gasket, a button, a main shaft, a main shaft screw, a locking spring and a button spring. The lock bridge can be automatically inserted into the locking groove or the closing groove formed in the cutting edge according to the rotation angle of the cutting edge under the pushing of the locking spring, the locking effect is automatically achieved, the lock bridge is provided with the locking contact face and is divided into the flat section and the inclined section with different angles, the double effects of abrasion compensation and locking safety are achieved, and the service life of the blade is prolonged. The locking structure is simple in structure and convenient to operate, does not need manual insurance operation, has the advantages of being convenient to control and firm in locking at the same time, operation gestures do not need fingers to appear on a blade turning-back path, and the locking structure only needs one main shaft screw for fastening, does not have any specific structure exposure in appearance and has the advantages of being simple and attractive. According to the invention, the overall occupied space is small, avoiding interference to the cutting edge is little, the storage proportion during closing is high, and the advantage of saving space is achieved.

This application discloses a hemostatic device, including a carrier cap, a fitting forceps, a guide tube, a driving component, and multiple hemostatic clips. The carrier cap includes a fixed end cap and a rotating end cap. The fixed end cap is fixedly fitted onto the distal end of the endoscope, and the rotating end cap is rotatably fitted onto the distal end of the endoscope. Multiple hemostatic clips are disposed inside the rotating end cap, and the hemostatic clips are integrally connected to the rotating end cap via at least one connecting portion. The fitting forceps are configured to extend into the rotating end cap through the instrument channel of the endoscope, and to clamp and apply force to the hemostatic clips to break the connecting portion, thereby removing the hemostatic clips from the rotating end cap, and to control the closure of the hemostatic clips. The driving component is located at the proximal end of the endoscope, and the rotating end cap is connected to the driving component via a rotating driving tendon. The guide tube is located on the outer peripheral wall of the endoscope, and the rotating driving tendon passes through the fixed end cap and the guide tube. The driving component is configured to drive the rotating end cap to rotate via the rotating driving tendon. This hemostatic device can shorten the operation time when used.

The utility model relates to underwater archaeological instrument technical field, concretely relates to a kind of underwater archaeological multilayer screening box, including box, at least one water inlet is equipped in box top, screening cavity corresponding with water inlet is equipped in box, collecting cavity is opened in the place of screening cavity just below in box, collecting assembly for collecting filtering residue is equipped in collecting cavity, several pullable drawers are slidably arranged in screening layer along height direction, and the mesh number of upper drawer screen is less than the mesh number of lower drawer screen, and the bottom of drawer inboard wall is fixedly connected with several support rings along its circumference direction. The utility model is filtered by the filter screen of different mesh number, and small cultural relics and tiny sample cultural relics in archaeological site are screened out, so that the loss of archaeological sample with silt is reduced.

The utility model relates to a gas circuit structure of an air compressor, which comprises a first compressor, a second compressor, a driving motor connected between the first compressor and the second compressor, and a filter arranged at a gas input end, the electromagnetic valve assembly comprises a first electromagnetic valve and a second electromagnetic valve which are arranged on one side of the filter; in a series connection mode, the first electromagnetic valve controls the first airflow passage to be conducted, the second airflow passage is closed, and external air enters the first compressor at the moment; in the parallel connection mode, the first electromagnetic valve controls the first air flow channel and the second air flow channel to be communicated, and air enters the first compressor and the second compressor. Series-parallel connection dynamic switching can be achieved, the series connection mode improves the pressure output capacity, the parallel connection mode meets the requirement for large flow, and the production cost is reduced while different pressure and flow requirements are met.

The utility model discloses a generator set air intake device, including the installation pipe, be equipped with the fan in the installation pipe, the fixed mounting of installation box and mounting seat has on the installation pipe, be equipped with two groups of symmetrical distribution's winding rod in the installation box, two groups winding rod all have the filter screen that has wound, two groups winding rod all have the disc spring that has sleeved, the winding rod upper end has two groups of ratchet that sets up reversely, be equipped with two groups with the ratchet corresponding setting's pawl in the installation box, be equipped with two groups of symmetrical distribution's cleaning brush in the installation box, the cleaning brush is attached with the filter screen outer surface, be equipped with two groups of symmetrical distribution's fixed link in the installation box, realize the conversion to the filter screen at the air inlet through the filter screen cooperation two groups winding rod, keep the clean of filter screen aperture, avoid the influence of the flow of air intake, clean the filter screen surface in time after using through the cleaning brush setting, reduce the input of manual labor.
