The present invention relates to water suction device with two ear handles specially designed for infant and child to drink liquid or water; it can automatically close the valve when not sucting water, and it can automatically supplement inlet air when sucking water and does not need to stop sucking. It is plastic cup and cover cable of heat insulating and preventing break while falling. The two ear handles on the cup body are made of soft plastic material. The top part of cup body and bottom part of cup cover has mutually matched thread, and on the external upper end of cup cover is attachedwith a suction mouth made of heat insulating flexible plastic material.

The invention discloses an eyeglasses protection pad, which comprises a pair of raised soft pads arranged at the edges of the upper ends of two eyeglasses lenses, wherein the raised soft pads are soft pads made of elastic material, and the thickness of the raised soft pads is 1 to 3 millimeters. When the eyeglasses protection pad is used, because the raised soft pads are small, the eyesight is not obstructed; when the eyeglasses are randomly laid on a table, the eyeglasses protection pad can play a role in supporting the eyeglasses and avoid the contact of the lens and the table to prevent the lens from being abraded; and in addition, if the eyeglasses are dropped accidently, the protection pad can also play a buffering role, protect the eyeglasses and avoid loss of property. The eyeglasses protection pad has simple structure, is economic and practical, and is convenient for popularization.

The invention relates to an oil pipe cutter. The oil pipe cutter is characterized in that the oil pipe cutter comprises a cutter body, wherein the cuter body is formed by extending a cutter root (3) to a cutter blade (1) through a cutter face (2), an installation hole (4) is formed in the center of the cutter body, the cutter face (2) is a full circle, and the thickness of the cutter face (2) is gradually increased from the cutter blade (1) to the cutter root (3). The oil pipe cutter has the advantages of being capable of resisting clamping, preventing break, and resisting shock, incisions of oil pipes are neat, chips are absent during cutting processes, and use requirements for cutting oil pipes on site can be met.

The invention provides a geotextile material. The geotextile material is characterized by comprising a stacked complex formed by stacking 16-3,000 layers of double-layer complexes of B and C, wherein B is glass fiber-modified polypropylene or carbon fiber-modified polypropylene, and C is HDPE (high-density polyethylene). The geotextile material is a novel multifunctional geotextile material integrating earth (sand) fixation, water seepage, breaking prevention and load bearing functions.

An electronic thermometer with heat conductive unit consists of a measuring end, a container, sensing element in container, wire and contact part. It is featured as forming said contact part to be pot cover form with certain radian and preparing said contact part by metal heat conductive material, embedding said contact part in said container and setting top surface of said contact to be higher than surface of measuring end of thermometer.

The invention discloses a method for manufacturing a rigid-flex PCB (printed circuit board). The method includes the following steps that S1, copper foil is cut; S2, the copper foil is coated with a cover membrane; S3, positioning is performed; S4, pressing is conducted, and the copper foil, the cover membrane, a prepreg and a rigid board are pressed; S5, cutting is carried out, the copper foil on the upper portion of the rigid board and the prepreg are cut and removed, and the rigid board below the cover membrane is removed. According to the method, the copper foil is directly coated with the cover membrane which replaces a traditional PI soft board material, so that the binding force between the copper foil and the cover membrane is high, the abnormal condition that the joint of a flex board and the rigid board is layered in the pressing process of the rigid-flex PCB is effectively avoided, and the problem that prepreg powder ejects the flex board after pressing is completed, and thus bad white spots happen to the board surface is further effectively solved; meanwhile, by the adoption of the manufacturing method, the production cost is lowered.

The present invention relates to an insulation rod assembling and disassembling ground lead assistant device. The device comprises: a detachable insulation operation rod body, a metal head arranged atthe top end of the insulation operation rod and ground lead hanging devices installed on the operation rod body at intervals. The insulation operation rod body comprises an upper rod body, a middle rod body and a lower rod body which are in threaded connection, each of the upper, middle and the lower rod bodies is respectively provided with the two ground lead hanging devices at intervals, the ground lead hanging devices can be detachably and foldingly installed on the upper rod body and the middle rod body. A first clamping plate, a second clamping plate and a first fixing bolt are employedto fasten a lantern ring to conveniently disassemble the ground lead hanging devices and regulate the positions of the ground lead hanging devices; when the insulation rod assembling and disassemblingground lead assistant device is completely used, a second regulation nut is loosened, a connection rod is folded upwards or downwards to be parallel to a corresponding rod body, and then the second regulation nut is screwed up so as to save the space; and moreover, the structure is simple, the design is reasonable, the operation is convenient, and the generation of the collision accident of the ground lead and live devices around is avoided. When the ground lead is assembled and disassembled, the insulation rod assembling and disassembling ground lead assistant device can avoid human body damaging by induced electricity.
