[0002] During construction, in order to measure the construction project, it is generally necessary to sample and test the concrete used to build the building. In the existing technology, shovels, hammers and other devices are generally used for sampling. Sometimes, impact drills are used to sample concrete. Compared with hammers and shovels, impact drills are faster and more convenient. However, impact drills may cause debris to fly, which is more difficult to collect.

[0003] Referring to Chinese Patent Publication No. CN219757764U, a sampling device for engineering quality inspection is disclosed, which includes an impact drill, a drill bit connected to the front end of the impact drill, a collar provided at the connection between the drill bit and the impact drill, an insert block provided on the front wall of the collar, a screw hole provided on the top surface of the insert block, a positioning block connected to the front end of the insert block, a socket provided on the rear wall of the positioning block that fits the insert block, and a through hole provided on the top of the socket that aligns with the screw hole. The utility model is configured such that when the drill bit contacts the wall, the sleeve also contacts the wall surface, forming a seal, and the rear end of the sleeve is connected to a spring rod, so that the drill bit penetrates the wall during drilling. At this time, the pressure of the sleeve moving backward is received and compressed by the spring rod, so that the collection port of the sleeve remains in contact with the wall, and all concrete crushed by the drill bit is collected by the sleeve, achieving the beneficial effect of higher efficiency and better collection effect when collecting concrete.

[0004] When the device is in use, although the sleeve can be used to collect flying debris, the collected debris will be stored inside the sleeve during the sampling process. The stored debris may rub against the drill bit and cause damage to the drill bit. In order to protect the drill bit, the sleeve needs to be dumped multiple times during sampling to discharge the debris inside, which is inconvenient to use. Therefore, a sampling device for engineering quality inspection is proposed to solve the above problem. Utility Model Content
