The invention provides an outlet pressing plate pin type experiment clip. An outlet pressure plate pin-type experimental clip, which includes a first clip, a second clip and a transition section, the first clip and the second clip are connected through the transition section, and the first clip A pin is set between the second clip and the first clip is provided with an experiment line connection hole, and a metal wire is arranged inside the experiment line connection hole, and the metal wire passes through the interior of the transition section and connects with the Pin electrical connection. The invention makes the signal current of the test line flow to the pin through the test line connection hole and the metal wire provided on the first clip of the test clip, and firmly clamps the first and second clips on the pin-type outlet pressure plate through the tensile structure superior.

The invention relates to a multifunctional wine cabinet. The wine cabinet comprises supporting plates, supporting frames, fixing pins, switches, hinges, cabinet doors and sponge bodies, wherein the two ends of the supporting plates run through via holes in the supporting frames respectively, and the supporting plates running through the via holes are fixed by making the fixing pins to run through bolt holes; the cabinet doors are fixed to the supporting plates through the hinges; the switches are hinged to the tops of the cabinet doors through transmission devices; when the switches are rotated clockwise, through the transmission devices, the cabinet doors rotate outwards with the hinges as fulcrums, and when the switches are rotated anticlockwise, the cabinet doors are closed; the sponge bodies are mounted at the bottoms of the cabinet doors; cup holders are arranged on the back surfaces of the supporting plates. The multifunctional wine cabinet is reasonable in structure design and easy and convenient to operate, and can effectively prevent jolting damage of wine when the wine is taken up and put down.

The invention discloses a carbon fiber walking stick which comprises a carbon fiber walking stick head and a first carbon fiber supporting pipe in matched connection with the walking stick head. The walking stick head is integrally formed with the first supporting pipe, and grooves are formed in the connecting position of the walking stick head and the first supporting pipe and are distributed in two sides of the connecting position to form a clamping portion. By the adoption of the structure, the potential safety hazard of an existing walking stick is effectively eliminated, and the carbon fiber walking stick is higher in reliability and is very suitable for patients, the old, outdoor travelers and other populations. The invention further discloses a manufacturing method of the carbon fiber walking stick. The manufacturing method is used for manufacturing the carbon fiber walking stick and is simple in steps and convenient to operate.

The invention discloses an oil drum carrying device for oil exploitation. The oil drum carrying device for oil exploitation comprises a carrying forklift main body, main body trundles and a forklift bearing plate are connected to the two sides of the bottom end of the carrying forklift main body correspondingly, bearing plate trundles are installed below the forklift bearing plate, a rotating baseis installed outside the upper portion of the carrying forklift main body, the top of the rotary base is connected with a supporting vertical rod, an extending fixing rod is installed at the top of the supporting vertical rod and is of a self-locking type telescopic rod structure, and an oil drum positioning rod is connected to the outer portion of the extending fixing rod and is of a J-shaped structure. According to the oil drum carrying device for oil exploitation, the position of an oil drum can be limited through the oil drum positioning rod, so that the oil drum is not prone to sliding down when a forklift moves down a slope. According to the oil drum carrying device for oil exploitation, the hook-shaped oil drum positioning rod is connected to the carrying forklift body through theextending fixing rod, so that the oil drum can be sleeved with the oil drum positioning rod to limit the oil drum.

The present invention relates to a cable quick connector, in particular to a cable quick connector with waterproof and fireproof performance, the cable quick connector includes a pair of upper covers made of high temperature resistant insulating material and a lower cover, wherein a plurality of vertical through holes for cables to pass through are opened in the middle of the lower cover, and a plurality of groups of metal needles are fixed on the inner side of the upper cover, and the metal needles include at least two needle-shaped conductors, The needle-shaped conductors are connected by wires, and the needle-shaped conductors are in one-to-one correspondence with the vertical through holes; the upper cover and the lower cover are connected by riveting, bolt fixing or bonding to form a closed The shell, the contact surface between the upper cover and the lower cover is equipped with a high temperature resistant sealing ring. This cable connector adopts a revolutionary new cable connection method, using metal needles to insert the wire core from the end face of the wire to form a path, with a significant contact area, which can significantly reduce the temperature rise of the contacts, the cable connection is firm, and the cable is in a natural state It will not slip off easily, effectively ensuring the connection of each cable.
