The invention discloses a self-locking type electrified lapping wire clamp. The self-locking type electrified lapping wire clamp comprises a top plate used for achieving an electric loop, a bottom plate used for forming a clamping structure with the top plate, a guide device used for allowing the top plate and the bottom plate to move in an opposite direction along a fixed track, a locking deviceused for fixing the top plate and the bottom plate at a working region and a handheld device used for moving. One end, far away from the locking device, on the top plate is provided with a wire connection portion used for connecting a newly added circuit. The whole self-locking type electrified lapping wire clamp is high in practicability and creativity, achieves quick connection and self-lockingwith the original wire, and is simple to operate and high in safety.

The invention relates to an elevator with multi-stage safety protection. Working ropes and safety ropes are arranged on the elevator, the elevator comprises at least one safety device, each safety device is arranged on the elevator and fixedly connected with the elevator, each safety device is glidingly connected with each working rope and each safety rope, respectively, a plurality of safety devices are symmetrically distributed and / or in stage-by-stage sequential connection, the stage-by-stage sequential connection means that the safety rope of the previous safety device is used as the working rope of the next safety device, and when a transmission rope of the electronically-controlled elevator breaks suddenly, each safety device can realize a self-locking function rapidly, so that the safety of the elevator is improved, and personal casualties are avoided; and the elevator is provided with the plurality of safety devices for multi-stage protection, so that the reliability is improved.

The invention discloses an unmanned aerial vehicle hold. The unmanned aerial vehicle hold comprises a set of parallel first connecting plates and a set of parallel second connecting plates, the bottoms of the first connecting plates and the bottoms of the second connecting plates are sealed through a bottom plate, and each first connecting plate and the corresponding adjacent second connecting plate are connected through a stand column on the corner; the corner position, close to one position, of at least one first connecting plate is provided with a movable locking block, a fixed locking block is arranged above each movable locking block, each fixed locking block can be arranged on a sliding rail of an unmanned aerial vehicle body, and the unmanned aerial vehicle hold can horizontally move along the sliding rail and is locked through the movable locking blocks and the fixed locking blocks. The unmanned aerial vehicle hold can be rapidly unloaded, loaded and self-locked.

The invention relates to a self-locking structure for a screen. The self-locking structure comprises a rotating shaft one end of which is provided with a screen connecting part, a steel ball guide rail is fixedly sleeved on the rotating shaft; the steel ball guide rail is provided with a first rail; the first rail comprises a downward pull rail groove formed in the outer surface of the steel ball guide rail and a limit rail groove; the downward pull rail groove is arranged close to the screen connecting part; the rotating shaft is sleeved with a shell in a rotating way; the shell is provided with a cavity capable of movably accommodating the steel ball guide rail; a second rail is concavely arranged on the inner wall of the cavity along the axis direction of the rotating shaft; steel balls are movably mounted on the first rail and the second rail; a first connection part used for fixedly mounting a screen spring is arranged on one end, far away from the screen connecting part, of the shell; the other end of the rotating shaft penetrates through and stretches out of the shell to form a second connecting part. The self-locking structure of the screen is unique in structure, the rapid self-locking is realized under the counter-acting force effect of the screen spring after the screen is pulled down, the self-locking stability is stronger, the convenience and rapidness in use are improved, and the production cost is lower.

Provided is a mouse trapping cage. One side of a base body is hinged to one side of a cage body. The bottom of a self-locking part is connected with the other side of the base body. The top of the self-locking part is provided with a clamping position for locking the cage body and the base body. A first connecting rod is connected with the cage body. One end of a top rod and the first connecting rod are buckled. The other end of the top rod and the locking rod are connected. A spring pressing piece is installed on the first connecting rod. An installation base is fixed to the base body. A groove locking position is arranged at one end of the installation base so that the locking rod can be placed at the groove locking position when the cage body is opened and the opening state of the cage body can be kept. The other end of the installation base is fixedly connected with the tail portion of a trigger ring through a rotating shaft. A rotating shaft is sleeved with a reset spring. One end of the reset spring abuts against the base body, and the other end of the reset spring is connected with the tail portion of the trigger ring. The two ends of the locking rod are located at the tail portion of the trigger ring. When the trigger ring is pressed down, the tail portion of the trigger ring is lifted up so that the locking rod can be disengaged from the groove locking position. One end of the self-locking spring is connected with the base body, and the other end of the self-locking spring is connected with the cage body. The mouse trapping cage is sensitive in reaction, rapid in self-locking operation, and capable of reducing the vigilance of mice and increasing the mouse trapping rate.

The invention relates to a portable multi-purpose quick self-locking fixture. The fixture comprises a clamping device, wherein the clamping device adopts a wedge clamping mechanism, the wedge clamping mechanism comprises a wedge column (11) and rollers (12), a piston rod mounting screw hole is formed in the back end surface of the wedge column (11), and the rollers (12) are arranged on two sides of the wedge column (11). Compared with the prior art, the fixture has the beneficial effects as follows: clamping self-locking is controlled by the aid of a single air source, and the fixture can clamp a to-be-machined part firmly and realize quick self-locking in an instant and can also release the to-be-machined part in an instant after machining is completed, so that the mounting and dismounting efficiency is substantially improved; the fixture is high in universality and applicable to machining equipment such as machining centers, gang drills, drilling machines, milling machines, special machines and the like; the fixture is small in shape and portable, an air cylinder can be used as a handle when the self-locking fixture is required to be moved on a workbench, thus quick movement is realized, and then machining of multiple to-be-machined planes or machining in multiple steps such as surface reaming, tapping, hole drilling, hole reaming and the like is realized.
