The invention discloses a kit for detecting goat pox virus. Include at least four primers of SEQ No. 1, SEQ No. 2, SEQ No. 3 and SEQ No. 4 in the kit of the present invention, also have dNTP, Tris-HC, KCl, (NH4) 2SO4, MgSO4, Tween20 and Bst in the kit enzyme, and template DNA. The primer of the invention has specificity, and cannot amplify the nucleic acid of sheep pox virus under the same conditions, and meanwhile, the detection sensitivity of the invention is high, and meanwhile, the detection operation is relatively simple and fast.

The invention provides an internal size detection device of a paper box. The device comprises a rectangular bracket. The rectangular bracket is composed of struts. A chute is arranged in each strut. The struts are connected through the chutes. Each strut is provided with a lifting mechanism. A scale is arranged on the surface of each strut. The bracket is placed into the paper box, and then the struts are adjusted by the scales to correspond to four side corners of the paper box. The bracket is taken out, and the length, the width and the height of the paper box can be directly acquired. The device has the advantages of simple and fast detection and high detection accuracy.

The invention discloses a method for testing opening and closing pressure of a gum cap of a safety valve of a lead-acid accumulator and a special testing device thereof. The method comprises the following steps: (1) testing in an environment at a temperature of between 20 and 30 DEG C, connecting the safety valve to a liquid filling port on a battery middle cap of the special testing device, dripping a proper amount of water in a groove surrounding the liquid filling port, covering a transparent cover plate on the battery middle cap, and inserting the pipe orifice on one end of a plastic pipeinto a liquid filling port under the battery middle cap; and (2) closing a pressure relief valve in the plastic pipe, opening a stop valve, pressurizing a boost valve, recording the reading on a pressure gauge when air bubbles emerge from the lower edge of the rubber cap as a open valve pressure, closing the stop valve, opening the pressure relief valve to relive pressure, and recording the reading on the pressure gauge when no air bubble emerges from the lower edge of the rubber cap and the pointer on the pressure gauge does not fall any more as a closed valve pressure. The method has the advantages that: the testing operation is convenient, visual and quick; and the tested data can be completely used for the quality control of the safety valve and production instruction.

The invention discloses a device for detecting the symmetry of a gearshift swing lever ball head. A positioning shaft is arranged on a bottom plate. A first support base is arranged on the back side of the positioning shaft; the first support base is composed of a vertical section and a transverse section; a lining is fixedly inserted in the vertical section of the first support base; a positioning pin passes through the lining; the positioning pin is a three-section cylindrical structure with the front part relatively small and the back part relatively big; a second support base is arranged on the right side of the positioning shaft; a through-groove is formed in the upper part of the second support base; the grooved opening of the through-groove is sealed by a cover lid which is fixed to the second support base via a bolt; a measuring shaft passes through the through-groove, and the measuring shaft is square column-shaped and moves in left-right direction; the left end of the measuring shaft is provided with a front measuring block and a back measuring block which are parallel and symmetrically arranged; a test opening is formed between the two measuring blocks. The device for detecting the symmetry of the gearshift swing lever ball head has the advantages of smart design, simple and compact structure, fewer parts, convenient assembling, convenient, quick and labor-saving detection operation, accurate and reliable detection results and high detection efficiency.

The invention discloses a measuring tool for symmetry of a ball of a shift swing rod. A positioning shaft is disposed on a base plate. The upper portion of the positioning shaft is equipped with a positioning hole in a radial direction. A first supporting stand is disposed behind the positioning shaft. A lining is fixedly embedded to the first supporting stand. A positioning pin passes through the lining. The front end of the positioning pin can pass through the positioning hole. A second supporting stand is disposed on the right side of the positioning shaft. The upper portion of the second supporting stand is equipped with a through groove, the notch of the groove is sealed by a cover plate, and the cover plate is fixed to the second supporting stand through bolts. A measuring shaft penetrates the through groove. The measuring shaft is a square column and can move leftwards and rightwards. The left end of the measuring shaft is equipped with two measuring blocks front and back. The two measuring blocks are parallel and symmetrical to each other, and a detection opening is formed between the two measuring blocks. The measuring tool is ingenious in design, simple and compact in structure, is convenient to assemble, and is equipped with fewer components. Moreover, the measuring tool is easy, fast and labor-saving to operate, provides an accurate and reliable detection result, and is high in detection efficiency.

The invention discloses a method of detecting ball grooves of a waveform surface of a shift swing rod. A measuring tool comprises a base plate, a positioning shaft, a first supporting block, a lining, a positioning pin, a second supporting block, measuring blocks, and a cover plate. The method comprises the following steps: 1) sleeving the positioning shaft with a spindle sleeve of a shift swing rod, and make the first ball groove of a waveform surface of the shift swing rod face the positioning pin; 2) enabling the right end of the positioning pin to press against the first ball groove of the waveform surface; 3) controlling the first measuring block to move leftwards to check whether a clamping groove in the left end of the first measuring block can clamp a ball head; 4) controlling the positioning pin to loosen the shift swing rod so that the second ball groove of the waveform surface of the shift swing rod faces the positioning pin; 5) enabling the right end of the positioning pin to press against the second ball groove of the waveform surface waveform surface; and 6) controlling the second measuring block to move leftwards to check whether a clamping groove in the left end of the second measuring block can clamp a ball head. The method can detect the positions of the two ball grooves of the waveform surface of the shift swing rod, is simple, fast and labor-saving to operate, and provides an accurate and reliable detection result.
