The invention provides a detachable handle device with multiple locking functions, including a slide plate, an upper locking block, a push twist, an upper cover, a lower cover, a sliding plate spring, an upper locking block spring, an upper unlocking button, a lower locking block, lower locking block spring, lower unlocking button, pinch plate and pinch plate spring; the push button can drive the slide plate to move back and forth, and the upper unlocking button and upper locking block groove are arranged at the front of the handle cavity, and the upper locking block groove is provided with There is a spring and an upper locking block, and the upper locking block is always under the upward force of the spring; after the upper locking assembly, there is a lower unlocking button and a lower locking block slot, and a gusset assembly is provided at the end of the slide; the upper locking The assembly, the lower locking assembly and the rear end gusset cooperate to realize the locking of the handle. The pot handle is easy to disassemble, and one pot handle can be matched with multiple pots, so that it is easy to disassemble and assemble, and one handle has multiple pots. At the same time, the setting of multiple locking components can prevent the handle of the pot from falling off automatically when external force or misuse occurs, and the use safety is higher.

The invention discloses an anti-drop hanger which is additionally provided with a self-locking mechanism compared with general hangers, and a closed loop can be formed between a hook and a hanger body and automatically locked without self-opening after the hanger is normally suspended, thereby preventing the hanger from non-artificially and automatically dropping under a suspension state. In order to achieve the aim, the anti-drop hanger comprises a hook 1 and a hanger body 2, wherein the hook 1 is provided with the self-locking mechanism, the closed loop can be formed between the hook 1 and the hanger body 2 and automatically locked after the hanger is normally suspended, the free end of the hook 1 is used as a suspension end, and the other end of the hook 1 is connected with the hanger body 2. The invention has the advantages of simple structure, convenient operation and good firmness.

The invention provides a hot stamping die structure which comprises an upper die with a plunger chip, a core die, a core die frame and a base plate, wherein the core die frame is installed on the base plate through fixing plates which are located at the two sides of the core die frame; the core die is provided with a stamping cavity; the plunger chip is a hexagonal plunger chip; the core die frame is provided with a first ejecting hole and a second ejecting hole; the core die is erected on the core die frame through a rotation mechanism and is butted with the first ejecting hole and the second ejecting hole; and an ejecting mechanism which is used for supporting blanks and ejecting finished products out is arranged between the core die frame and the base plate. In the whole hot stamping process, the automatic ejection of the finished products from the die is achieved by the hot stamping die structure without manual operation of a worker, so that the production is simple; and the finished products can be smoothly ejected out by using the ejecting mechanism, thereby brining convenience for continuous production and greatly improving production efficiency.

The invention discloses an extendable prosthesis for children. The extendable prosthesis comprises a jacket, an inner core, a plurality of unidirectional buckle assemblies, a plurality of bidirectional buckle assemblies and a sealing ring. A slide hole is formed in the jacket, an opening is formed in the bottom of the slide hole, the inner core is slidably arranged in the slide hole of the jacket and is in close fit with the slide hole of the jacket, stepped clamp sections are arranged at the lower end of the slide hole, a liquid injection hole which is communicated with the slide hole is formed in the jacket, all the unidirectional buckle assemblies are equidistantly mounted on the left and right side walls of the inner core, all the bidirectional buckle assemblies are equidistantly mounted on the front and rear walls of the inner core, and the sealing ring is arranged at the end of the top of the inner core. The extendable prosthesis has the advantages that the unidirectional buckle assemblies are matched with the clamp sections of the slide hole, so that the inner core can downwardly slide relative to the jacket without upwardly sliding; upper and lower positioning grooves are formed in the slide hole, smooth oblique planes are respectively arranged on two side surfaces of each positioning groove, the positioning grooves are matched with the bidirectional buckle assemblies, and accordingly the problem that an existing inner core downwardly slides relative to an existing jacket to automatically fall off without external force or under the effect of low external force can be solved.

The invention discloses a compact circuit breaker of a grounding circuit. The structure of the compact circuit comprises a rear shell, wiring devices, a front cover, an assembly nut, a wiring label, amanual panel, a signal indication lamp, a reset button and a manual switch, wherein the front cover and the rear shell are connected in a buckling mode, and two wiring devices are arranged and are arranged at an upper end and a lower end of a middle part of the front cover by an embedment mode. The compact circuit breaker has the beneficial effects a wire core of a cable penetrates through the wiring devices via an incoming line hole in a wire clamping rack and then is upwards pulled and fixed by a warp plate, a high-efficient fixing effect can be achieved by anti-slip sawtooth, the raising and the descending of a wire clamping device can be conveniently controlled by a line loosen lifting handle, wiring convenience is improved, and the wire core of the cable is effectively prevented fromautomatically falling off.
