DETAILED DESCRIPTION

[0027] Below will combine attached Figures 1-5 , the technical scheme in the embodiment is clearly and completely described.

[0028] Specific implementation one: as Figures 1-2As shown, the clamp is composed of two clamp body parts 1, which are integrally formed and do not require thread processing, so the processing difficulty is low. The clamp body part 1 is semicircular. Two identical clamp body parts 1 are connected by the key groove pair 9 on the clamping surface of the base 3 fixedly installed at one end. The clamping cavity formed after the two identical clamp body parts 1 are clamped can accommodate the handle of the required ultrasonic probe 8, and there is a margin to clamp ultrasonic probes of different models. The base 3 is connected to the wire arrangement cavity through the reinforcing rib 2. The wire arrangement cavity is provided with wire arrangement openings 4 on both sides, which are convenient for the wire of the wired ultrasonic probe 8 to be arranged. The design of the double-sided wire arrangement opening 4 allows the two identical clamp body parts 1 to be symmetrically clamped. When in use, any wire arrangement opening 4 can be selected for wiring according to the needs. The probe cable can be arranged from one side of the clamp body part 1 after installation through the two wire arrangement openings 4. The clamp body part 1 is connected to the base 3 at the rear end through the reinforcing rib 2. The base 3 is square and is provided with a through hole. The installation hole is arranged on the tool flange of the mechanical arm.

[0029] The two sides of the clamp body part 1 are fixedly provided with protruding oval positioning members 10. When the two clamp body parts are clamped with each other, the two positioning members are combined to form an oval structure centered on the side buckle 5. The outer side wall of the clamp body part 1 is provided with a side buckle 5. The two clamped clamp body parts 1 are fixedly connected through the cooperation of the side buckle 5 and the positioning member 10. The outer side wall of the side buckle 5 is fixedly provided with a buckle handle 13. The buckle handle 13 is arranged on the long axis side of the central oval hole. The side buckle 5 is provided with a buckle positioning groove 12. The buckle positioning groove 12 is arranged on the short axis side of the central oval hole. The side buckle 5 is convenient for manual operation through the buckle handle 13 for fixing or loosening. The buckle positioning groove 12 prevents the side buckle from rotating.

[0030] The side of the clamp body part 1 is provided with a positioning member 10. The positioning member 10 is provided with a positioning rotation groove 17. The positioning member 10 can be cooperatively installed with a side fastener 6. The side and back of the clamp body part 1 are provided with an adjusting hole 11. The adjusting hole 11 is provided with a clamping adjusting bolt 7. The cavity at the adjusting hole is provided with a hexagonal groove, which can be embedded with a standard M5 hexagonal nut to adapt to the clamping adjusting bolt 7. The clamping adjusting bolt 7 can be installed through the adjusting hole 11. The entering depth of the clamping adjusting bolt 7 can be adjusted by rotating the clamping adjusting bolt 7. The threads required by the clamping adjusting bolt 7 are installed in the cavity wall in an embedded manner, which meets the requirement of limiting the freedom of the probe movement to achieve the fixed clamping of probes of different models.

[0031] The clamping cavity is larger than the handle volume of the common handheld ultrasonic probe 8. At this time, the movement state of the ultrasonic probe 8 is not limited. The coordinate system is established to illustrate the movement limitation of the clamp on the ultrasonic probe 8.

[0032] The ultrasonic probe 8 is defined as extending in the positive z-axis direction, and perpendicular to the fastening surface is defined as the x-direction. Each clamping body 1 has two adjustment holes 11 machined on its back, which can cooperate with clamping adjustment bolts 7 installed from the adjustment holes 11 on the outside of the clamping body 1. By rotating the clamping adjustment bolts, the movement of the probe 8 in the clamping cavity in the x-direction can be restricted longitudinally. For the y-direction, a clamping adjustment nut is mounted on the side fastener 6, and the movement of the probe 8 in the x-direction in the clamping cavity is also restricted by rotation adjustment, thereby realizing the clamping of the ultrasonic probe by the clamping device designed in this utility model.

[0033] Specific implementation method two: such as Figures 3-5 As shown, the internal structure of the positioning component 10 is divided into two parts: an outer guide hole and a rotating positioning groove 17. The outer guide hole can be used to insert the side fastener 6. By rotating it 90 degrees clockwise, the tightening sector lock 15 can hook onto the outer wall of the upper and lower clamping main body 1, providing support for the side clamping adjustment nut 7, thereby achieving the side clamping of the ultrasonic probe 8. At the same time, the reaction force applied by the ultrasonic probe 8 will also enhance the friction between the tightening sector lock 15 and the outer wall of the positioning rotating groove 17, further strengthening the fixed relationship between the two clamping main body 1.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments without departing from the scope of the present utility model's technical solution, based on the technical essence of the present utility model and within the spirit and principles of the present utility model, shall still fall within the protection scope of the present utility model's technical solution.
