[0010] In a preferred embodiment of the present invention, the length of the forceps arm is adjustable, and the forceps arm includes a plurality of telescopic sections which are nested.

[0011] The above technical solution can adjust the length of the tweezers arm according to actual conditions to meet usage requirements.

[0012] In a preferred embodiment of the present invention, two adjacent telescopic joints are interference fit or fixed by locking bolts.

[0013] In another preferred embodiment of the present invention, the outer sides of the two forceps arms are provided with anti-slip grooves.

[0014] In another preferred embodiment of the present invention, the cross-section of the tweezer head is a circle whose size is larger than the diameter of the tweezer arm or an ellipse extending along the length direction of the tweezer arm; when the cross-section of the tweezer head is a circle, the diameter of the tweezer head is 10-15mm; when the cross-section of the tweezer head is an ellipse, the long axis length of the tweezer head is 10-15mm, and the short axis length is greater than 2 / 3 of the long axis length.

[0015] In the above technical solution, the size and shape of the tweezer heads are reasonable, and cotton balls of different sizes can be easily clamped at the same time.

[0016] In another preferred embodiment of the present invention, a collar is clamped on the ends of the two tweezer arms fixed to each other, and the collar can slide on the tweezer arms toward the tweezer heads.

[0017] The above technical solution, by providing a sleeve ring, when the tweezers are not in use, the two tweezer arms are closed, and then the sleeve ring is slid toward the direction of the tweezer head, and the tweezers are kept in a closed state by the sleeve ring, which is convenient for storage.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0025] The utility model provides a medical cotton ball tweezers, such as Figure 1 As shown, the tweezers include two tweezer arms 10 arranged opposite to each other, one end of the two tweezer arms 10 is fixedly connected, and the other end of the two tweezer arms 10 is fixedly connected to a tweezer head 20 arranged opposite to each other, and the two tweezer arms 10 are in an open state by elastic force, and preferably, the outer side of the tweezer arms 10 is provided with an anti-slip pattern 12. The inner sides of the two tweezer heads 20 are both sunken to form a groove 21, and the two grooves 21 are arranged correspondingly, and the groove 21 is arranged through the outer side of the tweezer head 20, or the outer side of the tweezer head 20 is provided with a through hole 22 communicating with the groove 21.

[0026] The grooves 21 corresponding to the inner sides of the two tweezer heads 20 of the utility model can form a storage cavity for accommodating some cotton balls. By setting a through hole 22 communicated with the groove 21, the cotton balls can also be partially exposed through the through hole 22, which has a better clamping effect on the cotton balls, and the cotton balls are stable when wiping the surface of objects; and the groove 21 is a storage cavity, so that enough disinfectant or lubricating liquid can be retained on the cotton balls to ensure the wiping effect; in addition, the cotton balls are clamped by the grooves 21 and the through hole 22, and more areas of the cotton balls can be exposed between the two tweezer heads 20 and outside the through hole 22, thereby increasing the exposed area of ​​the cotton balls and achieving a good wiping effect. Especially when wiping the inner wall of a pipe, the cotton balls are exposed at multiple locations around the tweezer heads 20, and the wiping efficiency is higher.

[0027] In the present invention, the cross section of the tweezer head 20 is a circle whose size is larger than the diameter of the tweezer arm 10 or an ellipse extending along the length direction of the tweezer arm 10. When the cross section of the tweezer head 20 is a circle, the diameter of the tweezer head 20 is preferably 10-15 mm, and the tweezer head 20 is of suitable size and can clamp small and large cotton balls; when the cross section of the tweezer head 20 is an ellipse, the long axis length of the tweezer head 20 is 10-15 mm, and the short axis length is greater than 2 / 3 of the long axis length. It should be noted that, according to actual conditions, the tweezer head 20 can also be made into a variety of specifications according to size.

[0028] In another preferred embodiment, a plurality of saw teeth 23 are arranged around the groove 21 inside the tweezer head 20, and a tooth groove 24 is provided between two adjacent saw teeth 23. The saw teeth 23 are provided to increase the friction force and contact area with the surface of the cotton ball, making it easier to clamp the cotton ball. Preferably, the saw teeth 23 and the tooth groove 24 inside the two tweezer heads 20 are staggered and can be interlocked with each other, so that when the two tweezer heads 20 clamp the cotton ball, the saw teeth 23 and the tooth groove 24 are interlocked to ensure that the two tweezer heads 20 are aligned, which can avoid the situation where the saw teeth 23 scratch the wiping surface due to the staggered two tweezer heads 20.

[0029] In another preferred embodiment, the length of the forceps arm 10 is adjustable, and the forceps arm 10 includes a plurality of telescopic sections 11 arranged in a nested manner, and two adjacent telescopic sections 11 are interference-fitted or fixed by locking bolts to fix the length of the forceps arm 10. In normal state, the forceps arm 10 is shortened for easy storage, and conventional disinfection and lubrication can also be performed; when it is necessary to enter the elongated channel for disinfection or lubrication of its surface, the forceps arm 10 can be extended.

[0030] In another preferred embodiment, a collar 30 is further clamped on the ends of the two forceps arms 10 fixed to each other, and a step is provided on the forceps arm 10 to limit the left end of the collar 30 to prevent the collar 30 from being separated from the forceps arm 10. The collar 30 is sleeved on the two forceps arms 10 and can slide on the forceps arms 10 toward the tweezer head 20. In normal state, the two forceps arms 10 of the tweezers can be closed, and then the collar 30 can be slid to the right, and the collar 30 can keep the tweezers in a closed state for easy storage.
