[0003] A concrete strength detection device is disclosed in Chinese utility model CN217484025U. The concrete strength detection device realizes the function of conveniently replacing the extrusion head. When the connection between the extrusion head and the device body is to be released, it is only necessary to push both sets of push plates in the direction away from the extrusion head to the limit, and then pull the extrusion head in the direction away from the device body to remove the extrusion head. When the extrusion head and the device body are to be connected, it is only necessary to align the plug block with the slot and then push the extrusion head to the device body to the limit to connect the extrusion head and the device body. This solves the problem that most existing concrete strength detection devices cannot replace the extrusion head, and saves the cost of replacing the entire detection device when the extrusion head is damaged.
