This utility model discloses a porcine reproductive and respiratory syndrome virus (PRRSV) detection kit, relating to the field of detection kits. The PRRSV detection kit includes a kit body, a bracket at the bottom of the kit body, and a detection mechanism on the outside of the kit body. The detection mechanism includes a detection block disposed inside the kit body, a sealing block movably disposed above the detection block, and a fixing bracket movably engaged inside the bracket and movably disposed above the detection block, thus fixing the kit body and the bracket in place. This PRRSV detection kit allows for the determination of the injection site of the kit body without opening the kit body using the detection block. Subsequently, the sealing block sequentially seals the area above the kit body, and the moving fixing bracket secures all kit bodies above the bracket, reducing the complexity of this fixation method and ensuring that the use of the sealing block does not affect the overall fixation effect of the kit body and bracket.

The invention discloses a cardiovascular and cerebrovascular rehabilitation physiotherapy device which comprises a restraining piece, the restraining piece is provided with a fixing part, the middle of the restraining piece is disconnected and connected through a connecting piece, a first air bag and a second air bag are embedded in the inner wall of the connecting piece, and the first air bag and the second air bag are alternately arranged. A self-cleaning assembly for cleaning the surfaces of the first air bag and the second air bag is arranged on the inner wall of the restraining piece, and a pressure supply assembly for controlling the internal pressure of the first air bag and the second air bag to change alternately is arranged on the side end face of the restraining piece. The device can be suitable for the influence of vibration caused by frequent movement and high-strength use in an emergency department on equipment and internal medicaments, is convenient to use, can adapt to the use environment of rapid application in emergency treatment, and has better protection strength on the equipment and the medicaments.

The invention belongs to the technical field of electric welding machine supporting devices, and specifically discloses a portable overlapping structure of the secondary bottom line of an electric welding machine, comprising a connecting rod, a fixing piece is arranged on the outer wall of the connecting rod, a connecting assembly is arranged at the bottom of the connecting rod, both sides of the connecting assembly are fixedly connected with a connecting frame, one end of the connecting frame is provided with a fixing assembly, and two first magnetic blocks are arranged, the two first magnetic blocks are respectively placed on both sides of the connecting assembly and are far away from each other. In welding work, it is only necessary to fix it to one side edge of the welded object, so that one of the first magnetic blocks is far away from the welding area, and then even if the first magnetic block close to the welding area begins to decay due to the magnetism contained in the high temperature, the other first magnetic block can still maintain a strong magnetism to firmly fix the connecting assembly on the welded object, thereby solving the problem that the magnetic block is easily separated from the welded object in the prior art.

The invention discloses a coal mine digging and anchoring all-in-one machine construction testing device, and belongs to the technical field of mining, the coal mine digging and anchoring all-in-one machine construction testing device comprises a base and a cutting tool arranged above the base, a rock sample placing table is slidably arranged above the base, a moving plate is slidably arranged on the base, a cavity is formed in the rock sample placing table, and the moving plate is arranged in the cavity; the driving rack is fixedly arranged on one side of the moving plate; a two-way screw rod is rotationally connected into the rock sample placing table; according to the construction testing device for the coal mine digging and anchoring integrated machine, a hydraulic oil cylinder drives a moving plate to drive a cutting tool to move downwards, a driving rack is meshed with a gear ring, a driving part is matched to control a bidirectional screw rod to rotate, two clamping plates are close to each other, and then a rock sample can be automatically clamped and fixed; therefore, the rock sample is more stable in the cutting test process, the final test data is more accurate, and the construction test efficiency of the digging and anchoring integrated machine is improved.
