This clamping fixture can improve the stability of ultrasonic scalpel holder positioning, and has strong versatility, adapting to various types of ultrasonic scalpel holders, thereby improving the efficiency of production testing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a clamping fixture for ultrasonic scalpel testing, wherein the ultrasonic scalpel handle includes: a body and a fixed grip and a movable grip respectively disposed at the lower end of the body, the movable grip having a grip groove, the inner wall of the grip groove, the outer surface of the movable grip, and the upper surface of the body being curved surfaces, the clamping fixture including: a carrier plate for contacting and engaging with the lower surface of the ultrasonic scalpel handle, wherein at least 3 positioning blocks respectively corresponding to the grip grooves on the body, fixed grip, and movable grip of the ultrasonic scalpel handle are movably mounted on the carrier plate;

[0005] The corners of the triangularly arranged positioning blocks are arc-shaped. One corner of one of the positioning blocks is embedded in the grip groove and in contact with the inner wall of the grip groove. The upper surface of the ultrasonic scalpel handle body and the outer surface of the fixed grip are each in contact with at least one positioning block. A pressure block is installed on the upper surface of at least one positioning block, and a quick clamp is installed on the upper surface of at least one pressure block. One end of the clamping arm of the quick clamp can extend above the ultrasonic scalpel handle and is equipped with a chuck. An elastic pad for contacting and engaging with the upper surface of the ultrasonic scalpel handle is attached to the surface of the chuck opposite to the clamping arm.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above scheme, the quick clamp is a manual quick clamp or a pneumatic quick clamp.

[0008] 2. In the above scheme, the elastic gasket is a silicone gasket, a rubber gasket, or a polyurethane gasket.

[0020] The aforementioned positioning block 2 has a first strip-shaped mounting hole 41 extending along its length direction; the upper surface of the aforementioned positioning block 2 is provided with a pressure block 3, and the pressure block 3 has a second strip-shaped mounting hole 42 that intersects with the first strip-shaped mounting hole 41.

[0021] The first strip-shaped mounting hole 41 is set as a triangle with the same shape as the positioning block 2; the second strip-shaped mounting hole 42 is set perpendicularly to the center line of the second strip-shaped mounting hole 42.

[0022] Example 2: A clamping fixture for ultrasonic scalpel testing, wherein the ultrasonic scalpel handle includes: a body 101 and a fixed grip 102 and a movable grip 103 respectively disposed at the lower end of the body 101. The movable grip 103 has a grip groove 104. The inner wall of the grip groove 104, the outer surface of the movable grip 103, and the upper surface of the body 101 are all curved surfaces. The clamping fixture includes: a carrier plate 1 for contacting and engaging with the lower surface of the ultrasonic scalpel handle. At least three positioning blocks 2 are movably mounted on the carrier plate 1, respectively corresponding to the grip groove 104 on the body 101, the fixed grip 102, and the movable grip 103 of the ultrasonic scalpel handle.

[0023] The corners of the triangularly arranged positioning blocks 2 are arc-shaped. One corner of one of the positioning blocks 2 is embedded in the grip groove 104 and in contact with the inner wall of the grip groove 104. The upper surface of the ultrasonic scalpel handle body 101 and the outer surface of the fixed grip 102 are each in contact with at least one positioning block 2. A pressure block 3 is installed on the upper surface of at least one positioning block 2, and a quick clamp 6 is installed on the upper surface of at least one pressure block 3. One end of the clamping arm 61 of the quick clamp 6 can extend to the top of the ultrasonic scalpel handle and is equipped with a chuck 62. An elastic pad 63 for contacting and engaging with the upper surface of the ultrasonic scalpel handle is attached to the surface of the chuck 62 opposite to the clamping arm 61.

[0024] The aforementioned quick clamp 6 is a pneumatic quick clamp; the aforementioned elastic pad 63 is a polyurethane pad.

[0025] The aforementioned positioning block 2 has a first strip-shaped mounting hole 41 extending along its length direction; the aforementioned first strip-shaped mounting hole 41 is set as a triangle with the same shape as the positioning block 2; the aforementioned positioning block 2 is an acute-angled triangular positioning block.

[0026] Working principle:

[0027] When using it, first place the ultrasonic scalpel handle to be clamped on the carrier plate, so that the lower surface of the ultrasonic scalpel handle is in contact with the upper surface of the carrier plate.

[0028] Then, embed one positioning block into the grip groove, place one positioning block on the side of the fixed grip away from the movable grip, and place one positioning block on the outer side of the upper end of the ultrasonic scalpel handle. Then, lock each positioning block onto the carrier plate by passing through the second strip mounting hole on the pressure block and the first strip mounting hole on the positioning block and threadedly connecting them to the carrier plate.

[0029] Before locking each positioning block, the position of each positioning block can be adjusted along the length of the first and second strip mounting holes respectively, so that the outer side of the positioning block is more closely fitted with the inner wall of the grip groove, the upper surface of the ultrasonic scalpel handle body or the outer surface of the fixed grip, thereby restricting the degree of freedom of movement and rotation of the ultrasonic scalpel handle in the horizontal direction.

[0030] After achieving horizontal positioning, the quick clamp is switched from the non-clamping state to the clamping state, causing one end of its clamping arm to rotate above the ultrasonic scalpel handle and the elastic pad on the clamp head to press and engage with the upper surface of the ultrasonic scalpel handle. This restricts the vertical vibration freedom of the ultrasonic scalpel handle, enabling omnidirectional positioning of the ultrasonic scalpel handle and improving the stability of the ultrasonic scalpel handle positioning to facilitate subsequent testing and other operations.

[0031] The aforementioned ultrasonic scalpel testing fixture can simultaneously restrict the horizontal and vertical degrees of freedom of the ultrasonic scalpel handle through the cooperation of the positioning block and the quick clamp, thereby improving the stability of the ultrasonic scalpel handle positioning to facilitate subsequent testing operations. It can also achieve quick clamping and unclamping of the ultrasonic scalpel handle, and has strong versatility, adapting to various models of ultrasonic scalpel handles, thus improving the efficiency of production testing.

[0032] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
