The invention belongs to the field of luggage, and particularly relates to conveniently-pulled luggage. The conveniently-pulled luggage comprises a luggage body, a drawbar, a controller, universal wheels, a climbing unit and an anti-skidding unit, wherein the drawbar and the controller are arranged on the top of the luggage body; the universal wheels are arranged under the luggage body; the left side of the luggage body is connected with the climbing unit and the anti-skidding unit; a cuboid-shaped mounting groove is formed in the left side of the luggage body; the drawbar is positioned on theleft side of the controller; the climbing unit is positioned on the left side of the anti-skidding unit; a drawing plate can be pulled on a stair sliding plate; the right upper part of the stair sliding plate is connected with a damping device; a telescopic element is used for pushing the climbing unit; the cuboid-shaped mounting groove is used for mounting a telescopic element; a motor is used for driving a positive rotation sliding block and a negative rotation sliding block to move on a bidirectional lead screw in the backward direction; the anti-skidding unit is used for supporting the luggage and also has a damping effect, so that the stability of the luggage is further improved; a clamping buckle is arranged on the left side surface of the luggage body and is used for retracting theanti-skidding unit.

The invention discloses a convenient-to-move lifting support for mining equipment. The lifting support comprises a mining trolley body, fasteners and a fence, wherein a direction part is fixed on thesurface of the front end of the mining trolley body; an electric lifting platform, a stabilizing seat and an equipment placing area are sequentially arranged inside a lifting device from bottom to top; a reflecting strip is arranged on the surface of the rear end of the mining trolley body; the fasteners are arranged on the surface of the rear end of the equipment placing area; damping springs arearranged on the surfaces of the two sides of the lower end of the mining trolley body; connecting shafts are arranged on the two sides of a limiting piece; the fence is arranged on the inner surfaceof the equipment placing area; and second rotating shafts are fixed inside the fasteners. According to the convenient-to-move lifting support for the mining equipment, the damping springs are fixed onthe lower end of the mining trolley body so that a certain damping effect on the trolley body at the upper end can be achieved, and the equipment inside the device cannot be influenced easily even ifthe trolley is on a bumpy road; the fence is arranged so that the internal working equipment can be well protected, and potential safety hazards can be reduced; and the lifting support can well copewith the road conditions of the mining area.

The invention discloses a novel wiring harness connector. The novel wiring harness connector comprises a framework, wherein extension springs are symmetrically fixed on the top of the inner cavity ofthe framework; the bottom ends of the extension springs are connected with pushing parts; the top ends of the pushing parts penetrate through the framework; the inner cavity of the framework is provided with a pushing plate which is positioned below the pushing parts; the bottom of the pushing plate is connected with a pushing rod; one end of the pushing rod penetrates through the bottom of the framework, the other end of the pushing rod penetrates through a connecting plate, the bottom end of the pushing rod is fixedly connected with a pushing rod plate, the bottom of the framework is symmetrically provided with dampers; the dampers are positioned between the framework and the connecting plate; the connecting plate is provided with a bottom plate through symmetrical screws; and the bottomof the bottom plate is symmetrically provided with screw limiting holes. The novel wiring harness connector realizes collection or distribution of wiring harnesses, and protects the wiring harnesses,so that the wiring harness fixing effect can be realized, and the collection or distribution of the wiring harnesses can be freely regulated; and moreover, the novel wiring harness connector is convenient to dismount, is attractive, and has a wide application prospect.
