Strontium-running fold strontium pliers and processing method

Abstract

The invention discloses strontium-running fold strontium pliers and a processing method. The pliers comprise a left plier body and a right plier body, wherein pin joint grooves are respectively arranged on opposite inner sides of the right and left plier bodies; the right plier body and the left plier body are jogged through the pin joint grooves; a second pin joint groove in the position corresponding to the position of the pin joint groove on the inner side of the left plier body is arranged on the outer side of the left plier body and is provided with a cover plate; the upper and lower ends of the cover plate along the length direction of the plier bodies are fixedly welded with the joint surface of the right plier body; axle holes are correspondingly arranged on the cover plate, the left plier body and the right plier body; and pivots for folding and unfolding the plier bodies are assembled in the axle holes. The pliers can be designed with round fold strontium structure, thus reducing the fold strontium surface exposed when the plier bodies are unfolded to the greatest extent, ensuring the structure to be more compact and beautiful, solving the defect that the traditional strontium-running square fold strontium pliers processing method can not be used for processing the compact strontium-running round fold strontium pliers in the past, filling in the gap in production of the strontium-running round fold strontium pliers and beginning a new era.

Description

technical field [0001] The invention relates to medical forceps and scissors, in particular to a strontium-piercing strontium-stacked forceps and a processing method thereof. Background technique [0002] The strontium structure of the existing medical instrument forceps and scissors products includes three types: round strontium, square strontium and strontium-piercing square strontium. Such as figure 1 , figure 2 Shown is a schematic diagram of the structure of the circular stacked strontium pliers. The upper ends of the two pliers 1 and 2 are each provided with a recessed pivot joint groove 4 on the inner surface opposite to the upper end. The two pliers bodies 1 and 2 are stacked and fitted according to the pivot joint groove 4. Together and connected by screws 3, the upper and lower ends of the pivot groove 4 along the length direction of the pliers are in a symmetrical arc or circular arc shape. 12 is less, more beautiful, its disadvantage is that the force of the ...

Problems solved by technology

like figure 1 , figure 2 Shown is a schematic diagram of the structure of the circular stacked strontium pliers. The upper ends of the two pliers 1 and 2 are each provided with a recessed pivot joint groove 4 on the inner surface opposite to the upper end. The two pliers bodies 1 and 2 are stacked and fitted according to the pivot joint groove 4. Together and connected by screws 3, the upper and lower ends of the pivot groove 4 along the length direction of the pliers are in a symmetrical arc or circular arc shape. 12 is less, more beautiful, its disadvantage is that the force of the clamp body is equivalent to the cantilever beam form, which is not ideal, and because the joint surface of the side of the screw 3 and the counterbore of the clamp body 2 is quite small, it is easy to make the side joint wear, causing the pliers to lose their normal function; image 3 , Figure 4 It is a schematic diagram of the structure of the square stacked strontium pliers. The square stacked strontium pliers are also stacked and fitted together by two pliers 1 and 2 according to the pivot joint groove 4. They are also connected by screws 3, which are different from the round stacked strontium pliers. Yes, the upper and lower ends of the pivot joint groove 4 are linear, so that when the two pliers are opened, the stacked strontium surface 12 is exposed, which is not beautiful enough. Damaged Cons

[0003] The strontium piercing square stacked strontium pliers basically overcome the above-mentioned shortcomings of poor force and easy damage of the first two types of pliers, such as Figure 5 , Image 6 As shown, the strontium piercing type square stacked strontium forceps is characterized in that one of the forceps body 2 is provided with a strontium piercing hole 11, and the strontium piercing hole is an insertion slot, and the strontium piercing hole is heated and deformed so that the other forceps body 1 is inserted into the strontium piercing hole. Piercing the strontium hole 11, and then piercing the strontium hole through heating and reverse plastic deformation to keep the two pliers connected together; the advantage of adopting this structure is that the force bearing mode is changed from the cantilever beam type to the double support type, and the firmness is stronger th
