The invention relates to a recyclable expansion anchor rod and a construction method thereof. The recyclable expansion anchor rod comprises an anchor head, a rod body, a protecting bag and a rod body protecting tube; the anchor head is composed of a screw, a herringbone expanding head, a spiral steel wire, a steel wire protecting tube and an anchoring piece; the herringbone expanding head is screwed in the screw; the spiral steel wire penetrates the herringbone expanding head to extend into the steel wire protecting tube; the steel wire protecting tube sleeves the screw; the anchoring piece is mounted at one end of the rod body; the rod body is composed of a plurality of equidistantly arranged steel strands, steel strand position fixing parts and steel strand tensioning parts, and the steel strands are respectively fixed on the anchoring piece, the steel strand position fixing parts and the steel strand tensioning parts; the protecting bag is arranged outside the anchor head; the rod body protecting tube sleeves the rod body and are in butt joint with the protecting bag. The recyclable expansion anchor rod and the construction method thereof have the advantages that simpleness in structure, convenience in mounting, repeated use and low cost are achieved and the like.

An aircraft seat fixing apparatus includes at least one insertion region and at least one retaining element, both of which are provided for fixing a shell half to a bracket. The insertion region comprises a recess for enabling the retaining element to be inserted into the insertion region by means of an insertion movement which has a component perpendicular to a main direction of the extent of the retaining element.

The invention relates to the field of optical connectors, in particular to a sealing accessory for an optical fiber connector and an optical fiber connector using the sealing accessory. The sealing accessories for optical fiber connectors include adhesive sleeves, sleeves and lock nuts. The front end of the sleeve is provided with threads for threaded connection with the optical connector housing, and the inner wall of the sleeve is provided with a The back end of the bonding sleeve is provided with a stop section, which passes through the stop edge in the sleeve backward, and there is a stop between the lock nut and the sleeve for simultaneous contact with the bonding sleeve. section and the anti-rotation sleeve of the lock sleeve anti-rotation fit. Since the rear end of the bonding sleeve is provided with an anti-rotation section, and the anti-rotation sleeve is provided between the lock nut and the sleeve, the anti-rotation sleeve can be used when the sealing accessory is assembled to the corresponding optical fiber connector. The relative rotation between the bonding sleeve and the sleeve is avoided, thereby preventing the optical fiber from being twisted, and solving the problem of inconvenient installation of existing connector accessories.

The invention discloses a fully automatic battery module locking device, which comprises: a battery module, on which a plurality of screw rods are arranged, each screw rod runs through the battery module group, and each screw rod includes a top end part and a threaded part The nut positioning mechanism is arranged on the side adjacent to the threaded part, and is used to locate the nut to be installed, so that the axis of the nut to be installed coincides with the axis of the screw rod, and each nut to be installed corresponds to a screw rod; the torque adjustable screw rod locking mechanism is arranged on The side adjacent to the top end is used to determine the locking torque, and under the action of the locking torque, the screw is driven to rotate around the axis of the screw, so that the nut to be installed is installed to a preset position of the threaded part. The invention realizes the automatic tightening of the screw and the nut through the nut positioning mechanism and the torque-adjustable screw locking mechanism, which not only avoids missing screwing, but also avoids inconsistent locking torque, so that the thickness of the battery module after locking is consistent, thereby reducing the It reduces labor costs and improves the quality and production efficiency of battery modules.

The invention provides a binding device for wooden poles, which comprises a U-shaped metal frame, a steel wire rope and a steel wire rope fixing piece. The wooden rod binding device of the present invention uses a U-shaped metal frame as a supporting point, uses a steel wire rope as a winding tool, and finally uses a steel wire rope fixing part to lock the steel wire rope, so that various materials are combined into a binding system to complete the binding process. The wooden pole binding The device has completely changed the traditional iron wire binding method, successfully avoiding the dead knot of the iron wire binding in the prior art, and the breakage of the iron wire caused by excessive tightening force, thereby preventing the iron wire from being broken due to the fatigue strength limit of the binding or due to torsional force. The twisting of the ambassador caused the collapse of the spanning frame, which completely eliminated the safety hazard of the spanning frame collapse and ensured personal safety and the safe operation of the spanning object. After the successful development of this achievement, it was immediately put into the field and received unanimous praise from the construction personnel during the field use.

The invention belongs to the field of screwdrivers, and particularly relates to a spring energy storage screwdriver. The problems that in the prior art, time and labor are wasted when a screwdriver isused for tightening a screw, and the screw cannot be continuously screwed are solved. According to the technical scheme, the spring energy storage screwdriver comprises a shell (1), a knife rod (2) and a coil spring (6); a transmission shaft (5) is fixedly connected to the inner end portion of the coil spring (6); one end of the transmission shaft (5) is connected with the knife rod (2); the other end of the transmission shaft (5) is connected with a knob (7); and the outer end portion of the coil spring (6) is fixedly connected with the shell (1). According to the spring energy storage screwdriver, continuous rotating of the knife rod can be realized through the coil spring, a user does not need to restore the positions of hands, alignment is not needed, and manpower and time are saved.The spring energy storage screwdriver is suitable for tightening or loosening various screws.
