Description

Reverse tweezers with adjusting function

Technical Field

The invention relates to the field of articles for daily use and medical supplies, in particular to reverse tweezers with an adjusting function.

Background

The tweezers in the prior art generally comprise two identical tweezers arms, wherein one ends of the two tweezers arms are fixedly connected to form a certain included angle, and the other ends of the two tweezers arms are used for clamping an object; when in use, a user is required to apply pressure to the two forceps arms to enable the heads of the two forceps arms to approach and clamp an object. The prior art forceps have the defects that: 1. if the user needs to clamp the object for a long time, the user needs to correspondingly clamp the tweezers for a long time, which is not convenient enough; 2. the included angle of the two forceps arms is fixed and cannot be adjusted.

Disclosure of Invention

The technical problem to be solved by the invention is that the tweezers in the prior art are not suitable for clamping objects for a long time and do not have an adjusting function.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows: reverse tweezers with an adjustment function, comprising:

one ends of the two forceps arms are connected with each other to form a connecting part, and the other ends of the two forceps arms are oppositely and crosswise bent to form a clamping part; the reverse tweezers enable the clamping part to be in a closed state in a natural state, and can clamp objects for a long time; when a user presses the two forceps arms, the clamping part is loosened;

the adjusting mechanism comprises a sliding block and an adjusting rod, the sliding block is arranged between the two forceps arms, one end of the adjusting rod is in threaded connection with the sliding block, the other end of the adjusting rod extends to the connecting part, and the sliding block is driven to move along the length direction of the forceps arms when the adjusting rod is rotated;

the adjusting rod can only rotate but cannot move back and forth between the two forceps arms, when a user rotates the adjusting rod, the sliding block in threaded connection with the adjusting rod cannot rotate under the clamping action of the forceps arms, so that the sliding block can only move back and forth along the adjusting rod, and the sliding block moving back and forth can change the included angle between the two forceps arms; because the tweezers are reverse tweezers, the clamping degree of the clamping part on the object can be changed by changing the included angle of the two tweezers arms, and a user can properly adjust the position of the sliding block according to the volume and the clamping degree of the object to be clamped, so that the effects of stably clamping objects with different sizes and avoiding damaging the object are achieved.

Further, hollow layers with uniform thickness are arranged in the two forceps arms, the hollow layers of the two forceps arms are equal in length and aligned in position; the hollow layer enables the clamping parts of the two forceps arms to be in full contact, namely the clamping surfaces of the two clamping parts apply uniform force to an object, the clamping parts are different from common forceps in that the contact surface is gradually enlarged after the tip is closed.

Further, the clamping part forms an included angle relative to the thickness direction of the forceps arm, and the included angle is 10-80 degrees; the clamping part of the forceps is inclined towards the upper surface direction or the lower surface direction of the forceps arm, so that a user can clamp a front object without inclining the forceps, and the forceps are very suitable for medical occasions such as cardiac surgery and the like.

Further, the bending part of the clamping part is positioned in the middle area of the clamping part.

Furthermore, the connecting part is provided with a through hole, and the other end of the adjusting rod is arranged in the through hole; in order to ensure that the adjusting rod cannot move back and forth, the other end of the adjusting rod is generally provided with a larger head which can be used for rotating, and a knob can be directly arranged at the other end of the adjusting rod; the knob is arranged in the through hole, so that the purpose of limiting the adjusting rod can be achieved, and the adjusting rod can be conveniently rotated.

Further, insert pieces are detachably arranged on the inner side of the clamping part, the surfaces of the two insert pieces are provided with concave-convex grains, and the concave-convex grains on the surfaces of the two insert pieces can be meshed with each other; the insert made of different materials and the different concave-convex lines can enable the reverse tweezers to stably clamp various objects.

Has the advantages that: (1) the reverse tweezers with the adjusting function are provided with the clamping parts formed by mutually reversely crossing and bending, so that the natural clamping function of the tweezers is realized, and the tweezers can stably clamp objects without force application of a user in a natural state; the included angle of the two forceps arms is controlled by the movable sliding block arranged between the forceps arms, so that the clamping degree of the reverse forceps is adjustable, objects with different sizes can be stably clamped, and the objects can be prevented from being damaged; (2) the reverse tweezers with the adjusting function are provided with the hollow layers in the tweezers arms, so that the clamping parts of the two tweezers arms can be in full contact, and the clamping surfaces of the two clamping parts apply uniform force to an object.

Detailed Description

The present invention will be described in further detail with reference to specific embodiments.

Example 1

As shown in fig. 1 to 5, the reverse forceps with an adjusting function of the present embodiment includes a forceps arm 100 and an adjusting mechanism 200;

the number of the forceps arms 100 is two, one ends of the two forceps arms 100 are connected with each other to form a connecting part 110, the other ends of the two forceps arms 100 are bent in a mutually reverse crossing manner to form a clamping part 120, the middle of the clamping part 120 is bent to enable the front part of the clamping part 120 and the forceps arms 100 to form an included angle a shown in figure 7, the included angle a is 10-80 degrees, a detachable insert 130 is arranged at the clamping surface of the clamping part 120, the surfaces of the two inserts 130 are provided with concave-convex grains, and the concave-convex grains on the surfaces of the two inserts 130 can be meshed with each; the hollow layers 140 with uniform thickness are arranged in the two forceps arms 100, the hollow layers 140 of the two forceps arms 100 are equal in length and are aligned in position;
