[0027] 1. This utility model, through the arrangement of a control block, clamping plates, torsion spring shaft, gears, rack, and spring, allows the clamping plates to be opened by sliding the control block, which in turn moves the rack. The rack, in a Z-shape, meshes with the two sides of the two gears. Therefore, the rack's displacement drives the two gears to rotate in opposite directions, thus opening the clamping plates. The mounting bracket can then be attached to the ultrasonic probe or removed from it. When the clamping plates need to be closed, simply stop pushing the control block. The torsion spring shaft drives the clamping plates to reverse and reset, and the spring drives the rack to slide in the opposite direction, thus closing the clamping plates and gripping the ultrasonic probe tightly, preventing the puncture frame from falling off or shifting. It facilitates quick assembly and disassembly, and there is no relative sliding friction between the operator's fingers and the structure, thus minimizing finger injuries.

[0028] 2. This utility model increases the friction between the clamp and the ultrasonic probe by setting an anti-slip pad, thereby further preventing the puncture frame from falling off or shifting, and increasing the stability of the structure; increasing the friction also prevents the structure from loosening or shifting.

[0029] 3. By setting a limiting rod, this utility model can prevent the clamp from opening if the operator's movements are large. The limiting rod can be rotated to move to the back of the rack. Therefore, when the clamp is about to open, the rack will abut against the rack on the back and cannot move, thus preventing the clamp from opening. Moreover, the limiting rod limits the rack by blocking, so the limiting rod does not need to be tightened and the resistance is small, thus avoiding injury to the operator's fingers when rotating the limiting rod; it also increases the structural stability and prevents the structure from loosening and falling off.

[0040] Embodiment two:

[0041] In order to further increase the structural stability, the following settings are made based on the above embodiment one.

[0042] Referring to Figures 1-3 In the above embodiment, the fixed frame 1 is provided with a limiting rod 15 penetrating through one side of the upper part, and the rack 13 is in abutment with the limiting rod 15. The staff can move the limiting rod 15 to the back of the rack 13 by rotating the limiting rod 15, so that the rack 13 cannot be displaced when the clamping plate 8 is ready to be opened, thereby preventing the clamping plate 8 from being opened. One end of the limiting rod 15 is provided with a thread, and the limiting rod 15 is threadedly connected with the fixed frame 1. The limiting rod 15 limits the rack 13 by blocking, so that the limiting rod 15 does not need to be tightened and the resistance is small, thereby avoiding the abrasion of the staff's fingers when rotating the limiting rod 15.

[0043] The implementation principle of the utility model is as follows: first, the staff slides the operating block 10 to drive the displacement of the rack 13. The rack 13 is in mesh with the two sides of the two gears 12 in Z shape, so that the rack 13 drives the two gears 12 to rotate in opposite directions after displacement, thereby opening the two clamping plates 8. Then the staff can paste the fixed frame 1 with the ultrasonic probe.

The limiting rod 15 limits the rack 13 by blocking, so that the limiting rod 15 does not need to be tightened and the resistance is small, thereby avoiding the abrasion of the staff's fingers when rotating the limiting rod 15.

[0046] After the puncture frame is installed, the staff passes the puncture needle through the clamping frame 6 from the top of the clamping frame 6. Then the staff tightens the second bolt 7, so that the clamping frame 6 is closed to clamp the puncture needle. If it is necessary to adjust the angle of the puncture needle, the staff first loosens the first bolt 5. Then the staff can rotate the clamping frame 6 to adjust the angle of the clamping frame 6 and the puncture needle. At the same time, the outer surface of the swing frame 4 slides in the adjusting groove 3. After adjusting to the desired angle, the staff tightens the first bolt 5 to limit the swing frame 4, thereby limiting the angle of the clamping frame 6.
