The invention relates to a blood taking needle. The blood taking needle comprises a needle cap, a needle core, an inner cover, an outer cover and a bottom cover. The end, provided with a needle head, of the needle core is inserted into the needle cap in a connecting mode, and the other end of the needle core is provided with a needle core platform. The needle core platform is in contact with inner cover rib positions arranged at the lower end of the inner cover, a spring on the lower portion of the needle core platform is connected to the inner wall of the bottom cover and located in a bottom cover cylinder integrated with the bottom cover, and a rib position oblique plane is arranged on the outer wall of the bottom cover cylinder, extends downwards to form a boss and extends upwards to form a rib position protruding part. When the needle core is not popped up, the inner cover cannot move inwards due to needle cap supporting and inner cover rib position buckling, the inner cover is kept at the proper position through out cover limiting ribs, the needle core is prevented from being popped up mistakenly, and safety is guaranteed. When the needle core shoots, the inner cover is expanded by the rib position oblique plane after moving downwards for a section of distance along the protruding part; when the distance between rib positions on the two sides of the inner cover is larger than the width of the needle core platform, the needle core is popped up, the needle head can align to the position accurately and quickly, and the pain suffered by a patient is relieved.

The invention provides an electric motorcar with a start-up protection device, and relates to the field of electric motorcars. After a key is inserted in, an electric motor car or an electric bicycle can be driven through rotating a switch handle, but when the driver is off the electric motorcar, as the key is not pulled out, accidental rushing out of the electric motorcar can be caused due to careless rotation of the switch handle, so that a protection switch device is added in a driving circuit of the electric motorcar, and linkage of the switch handle or a motor is controlled through the protection switch device, as a result, during unmanned driving, circuit connection of the switch handle or the motor is cut off through the protection switch device, and accidental rushing out of the electric motorcar caused by misoperation is prevented. In order to prevent misoperation of the electric motorcar after parking, the protection switch device 6 is mounted on a motorcar frame in front of a driver, when the driver is on the electric motorcar, an induction switch induces the driver, and the protection switch device is in a closed state, and when the driver is off the electric motorcar, the induction switch induces getting-off of the driver, and the protection switch device is in an off state, so that accidental rushing out of an electric motorcar due to misoperation is prevented.

A mounting device includes a case that has an insertion inlet for a mobile information terminal, a connector that establishes electrical connection to the mobile information terminal inserted in the insertion inlet, and an ejection mechanism that ejects the mobile information terminal after completion of processing through the connector. After the completion of the processing, by an action of the ejection mechanism, the mobile information terminal is popped up from the mounting device, and a user is understandably notified of the completion of the processing.

An anti-ejection apparatus for wafer units includes a lock bar and a guide pin. The lock bar alternately has a plurality of lock portions and a plurality of unlock portions. The lock portions are located at heights corresponding to those of insertion slots of a side plate of a cassette, and enable blocking of the insertion slots. The unlock portions enable unblocking of the insertion slots. The guide pin is connected to the lock bar and is disposed protruding downward from a bottom portion of the side plate of the cassette. When the guide pin is pressed upward at its lower end portion, the unlock portions and the insertion slots are communicated with each other. When the pressing of the lower end portion of the guide pin is cancelled, on the other hand, the insertion slots are blocked by lock portions.

The invention relates to a clamp for a cold upsetting tester of titanium alloy wires, which comprises an upper clamp, a lower clamp and a material mechanical property tester connected with the upper clamp and the lower clamp through large-bore screw threads. The clamp is characterized in that the center positions of the support faces of the upper clamp and the lower clamp are provided with grooves with depths of 5mm, the grooves are used for placing and positioning support boards and preventing the support boards from protruding accidentally; upper support boards and lower support boards which are cylinders with the thicknesses of 10 mm are arranged in the grooves, and the diameters of the supports boards are smaller than those of the grooves. The invention has the advantages that the tester is simple and practical and convenient for assembly and disassembly and has efficient and safe testing process, is easy to accurately realize the cold upsetting test of titanium alloy wires with set speed and requirements of forging reduction ratio on a common material tester, is favorable for the test analysis, has very good cold upsetting effect of the sample, low test cost and changeable support boards, thereby belonging to the very efficient and practical cold upsetting tester of the titanium alloy wires.
