The invention relates to the technical field of spraying bottles for containing liquid, in particular to a novel detachable and refillable liquid spraying bottle. The whole spraying bottle comprises a bottle body and a bottle bottom which are detachably connected through an integral valve seat. Positioning ribs, a seal groove and concave-convex toothed structures are disposed on the outer wall of the valve seat and connected with the bottle body. Threads are disposed on the outer wall of the valve seat and connected with the bottle bottom. A valve element is inserted in the inner cavity of the valve seat. The inner cavity of the valve seat is matched with the outer contour of the valve element and of an overall asymmetrical structure. The valve element can be inserted into the inner cavity of the valve seat at an only angle. A positioning device is disposed at the top end of the valve element and used for positioning an inner cavity spring. The overall asymmetrical structure of the inner cavity of the valve seat and the valve element is characterized in that one side of a contour line is a circular edge, and the other side thereof is a linear edge with an arc angle. The liquid spraying bottle has the advantages that the liquid spraying bottle is convenient to carry, convenient to demount and clean, good in airtightness and simple in production process, following rotation can be prevented, circulating refilling and repeated using can be achieved, and odor tainting of different gases is avoided.

The invention relates to an anti-falling device for a bolt. The anti-falling device comprises a substrate, a bolt, a fixing frame and a clamping plate, wherein the bolt is connected to the substrate; the fixing frame is fixedly connected with the bolt; the clamping plate is connected with the fixing frame; and the fixing frame and the clamping plate are positioned on both sides of the substrate respectively. According to the device disclosed by the invention, the fixing frame which is fixedly connected with the bolt and the clamping plate which is connected with the fixing frame are arranged on both sides of the substrate, so that the bolt is prevented from falling unexpectedly after a nut falls off.

The present invention discloses an open-typed ratchet spanner, which comprises a handle part that extends longitudinally and a jaw part composed of two separated claws; wherein, at least one claw is provided with a pallet with a workpiece occlusal surface on the end close to the jaw; the pallet rotates around a pivot which is perpendicular to the vertical shaft of the handle; when in a first position, the workpiece occlusal surface prevents the workpiece from breaking away from the jaw, when in a second position, the work piece occlusal surface allows the workpiece break away from the jaw. The open-typed ratchet spanner provided by the present invention has the advantage that the open-typed spanner can be inserted from the side and also has the advantages of continuous operation, simple structure and convenient use.

The invention relates to the technical field of locking devices, and discloses a bolt following rotation preventing device which comprises a sliding plate, a mounting plate and two plate sleeves. The plate sleeves are provided with sleeved connection parts, sleeve holes are formed in the sleeved connection parts, mounting holes and sliding grooves are formed in the mounting plate, the sleeved connection parts are inserted into the mounting holes, fixing pieces are inserted into the sliding grooves, the fixing pieces can slide along the sliding grooves, the fixing pieces are connected with the plate sleeves and the sliding plate, a clamping groove is formed in the sliding plate, and a limiting hole is formed in the position, corresponding to the clamping groove, of the mounting plate. A rotating shaft sequentially penetrates through the clamping groove and the limiting hole, the two ends of the rotating shaft are connected with the sliding plate and the mounting plate correspondingly, the clamping groove is provided with a limiting part and an unloading part which communicate with each other, the unloading part communicate extends towards the two sides of the limiting part, the rotating shaft is provided with an abutting connection part connected with the limiting part, the abutting connection part and the limiting part can be disconnected or connected by driving the rotating shaft to rotate, and the abutting connection part is connected in the unloading part in a sliding manner. According to the technical scheme, the bolt following rotation preventing device can avoid bolt following rotation, and the potential safety hazards that hands are pinched and people are hurt are avoided.

A locomotive fortuitous accident automatic warning help-seeking safety management system is characterized by at least comprising an induction assembly, direction lights and a parking light switch, wherein the locomotive fortuitous accident automatic warning help-seeking safety management system can be connected with a control system, vehicle states are detected through using of the induction assembly, signals of the direction lights and the parking light switch are utilized, and detection signals and switching signals are provided for the control system in good time; the control system is provided with an integrated circuit and a stabilization line, wherein the integrated circuit has the functions of starting mode detection, signal detection, calculation and analyzing, and the detection signals and the switching signals are converted into warning signals to be outputted to a control circuit; and the control system has the function of a digit type flasher and a direction light fault automatic inspection and warning function, and when any one direction light breaks down, a work indicating lamp shows in a mode of extinguishing / constant lighting or flicker frequency changing, or parking warning lighting is started. Fortuitous accident signals are detected, and various warning devises of a vehicle are started; lamp signals or sounds and others are emitted according to requirements; or through a mobile phone, a global positioning system (GPS) and the like, help-seeking information and safety warning help-seeking signals are sent out.
