Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in fig. 1-4, the present invention comprises an outer cover 1 and an ultrasonic probe 5, wherein the ultrasonic probe 5 can extend out of the outer cover 1 or retract into the outer cover 1 under the driving of a telescopic device.

The telescopic device comprises a power mechanism 6 and a telescopic assembly. The flexible subassembly includes along 1 axial settings of dustcoat and the first slide rail 8 of rigid coupling on 1 inner wall of dustcoat, sliding connection first slider 9 on first slide rail 8. The upper end and the lower end of the first slide rail 8 are respectively provided with a stopper for preventing the first slide block 9 from sliding out. The upper end of a second slide rail 3 which is arranged in the same direction as the first slide rail 8 is fixedly connected with a first slide block 9, and a second slide block 12 is connected on the second slide rail 3 in a sliding way. The upper end and the lower end of the second slide rail 3 are respectively provided with a stopper for preventing the second slide block 12 from sliding out. The upper end of the pull rod 4 which is arranged in the same direction with the second slide rail 3 is fixedly connected with a second slide block 12.
