[0009] As a further solution of the utility model, the size of the interior of the shell is matched with the size of the outer side of the installation sleeve, ensuring that the shell can be embedded in the interior of the installation sleeve, so that the shell can be supported and fixed.

[0010] As a further solution of the utility model, the waterproof pad, fireproof pad and moisture-proof layer are arranged in sequence inside the shell to ensure that the waterproof pad, fireproof pad and moisture-proof layer can all be arranged inside the shell, thereby playing the role of waterproofing, fireproofing and moisture-proofing for the interior of the shell.

[0011] As a further solution of the utility model, the shell and the fixing sleeve are arranged at the right end of the installation sleeve at the same level.

[0012] As a further solution of the utility model, the buffer is provided with two groups, and the two groups of buffers are respectively arranged at the front and rear ends of the shell, so as to ensure that the buffers on both sides can play a buffering role on the shell.

[0017] 1. The utility model is provided with a protective device, the shell is embedded in the other end of the installation sleeve, and the shell and the installation sleeve are fixed as a whole by a fixing bolt, so that the shell can protect the detection probe. In this process, the waterproof pad, the fireproof pad and the moisture-proof layer can play a role in waterproofing, fireproofing and moisture-proofing for the detection probe, and then play a protective role for the protective shell and the detection probe, so that the detection probe will not be corroded by air for a long time, and then prevent the problem of floating results in the detection results detected by the detection probe, and then ensure that the detection equipment can accurately perform strength detection on the concrete wall through the detection probe. Further, a buffer is arranged outside the shell, so that the buffer can play a role in buffering and unloading the shell and the detection probe, and then prevent the detection probe from being affected by the vibration force during the accidental landing, causing the detection probe to be damaged, and then causing the detection result to float, so as to achieve the protection of the detection probe through the protective device, prevent the equipment from being affected by the vibration, and cause the equipment to wear, and then solve the problem that the original equipment is easily affected by the vibration force during the accident, causing the equipment to be damaged, and then causing the detection efficiency of the equipment to decrease.

The shell 71 and the fixing sleeve 73 are arranged at the right end of the installation sleeve 3 at the same level.
