Double-purpose forceps

Abstract

The invention provides a pair of dual-purpose forceps, comprising a first forceps body and a second forceps body. When the first forceps body is connected with the second forceps body by means of a first pressurizing connecting member and a second pressurizing connecting member, a first handheld member and a second handheld member move towards each other, and a first pressurizing functional member and a second pressurizing functional member also move towards each other to complete pressurizing; when the first forceps body is connected with the second forceps body by means of a first opening connecting member and a second opening connecting member, the first handheld member and the second handheld member move towards each other, and a first opening function member and a second opening function portion face away from each other to complete opening. The dual-purpose forceps is simple in structure and is operated conveniently so that the double-purpose forceps can switch freely between opening and pressurizing functions conveniently and quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) A detailed description of the dual-purpose forceps of the invention is given below in combination with the embodiments of the invention:

(7) In order to achieve the purposes of the invention, FIG. 1 shows a three-dimensional structure diagram of the dual-purpose forceps. The dual-purpose forceps comprise two forceps bodies which are connected with each other through the articulated shaft and can be moved freely, and the two forceps bodies include a first forceps body and a second forceps body. Except for the connection mode of the articulated shaft, other proper connection modes can be also adopted certainly. The first forceps body 1 and the second forceps body 2 are made from the ixef 1022 plastic. The relief slots or the relief holes can be arranged in the forceps bodies 1 and 2, and in this way the dead weight of the forceps is reduced greatly on the premise of meeting the requirement of service strength of the forceps so that the physical load and fatigue of operation personnel are reduced. The hinge holes are arranged in the first pressurizing connecting member 14 and the first opening connecting member 15 of the first forceps body 1, and correspondingly the hinge holes are arranged in the second pressurizing connecting member 24 and the second opening connecting member 25 of the first forceps body 2; the positions of the hinge holes in the first forceps body 1 correspond to the positions of the hinge holes in the second forceps body 2 one by one separately; and the articulated shaft is used to disengage or engage the two forceps bodies 1 and 2. The outer edge of the head of the articulated shaft 3 is arranged to be non-circular, and the outer edge of at least one of two corresponding hinge holes connected through the articulated shaft is arranged to be non-circular coinciding with the outer edge of the head of the articulated shaft, and the non-circular is rhombus preferably, and can also be any other proper shape. The outer edge of the head of the articulated shaft the corresponding hinge holes coincide with each other, and have a certain rational clearance. Such design enables the articulated shaft 3 to conveniently and efficiently insert into or separate from the corresponding hinge hole in the function switching process of the forceps, and the forceps is facilitated to freely switch between the opening and pressurizing functions; the articulated shaft 3 is not liable to escape from the hinge holes in the using process and after disengagement and engagement. In order to avoid the situation that the hinge holes are worn in the long-time use process and consequently the service life of the forceps is shortened and the accuracy of the forceps is reduced, the wear resistant layers can be arranged on the inner walls of the hinge holes. In order to facilitate control over the rod, the shape of the first pressurizing functional member 12 of the first forceps body 1 is arranged to an arc, and the shape of the first opening function member 13 is arranged to a line; the shape of the second pressurizing functional member 22 and the second opening function portion 23 are symmetrical to the shape of the first pressurizing functional member 12 and the first opening function member 13, thereby facilitating control over pressurization and expansion of the rod. Certainly, the shape of the function portions on the first forceps body 1 and the second forceps body 2 can also be arranged to any other shape meeting the requirement of the using functions of the forceps. The U-shaped clamping slots which are perpendicular to the working faces of the first pressurizing functional member 12 and the first opening function member 13 are arranged in the first pressurizing functional member and the first opening function member, and the corresponding U-shaped clamping slots are also arranged in the second pressurizing functional member 22 and the second opening function portion 23. Certainly, the specific design form of the U-shaped clamping slots can also be determined according to the shape of the rod, and can be any other proper form. The opening size of the above U-shaped clamping slots can be determined according to the outer diameter of the specific rod; in order to prevent the U-shaped clamping slots from being worn by the rod, the wear resistant layers can be coated on the walls of the U-shaped clamping slots.

(8) FIG. 2 is a structure diagram of the pressurized state of the dual-purpose forceps. When the first pressurizing connecting member 14 on the first forceps body 1 and the second pressurizing connecting member 24 on the second forceps body 2 can be rotated through the articulated shaft 3 freely and the first opening connecting member 15 on the first forceps body 1 is disengaged from the second opening connecting member 25 on the second forceps body 2, the first pressurizing connecting member 12 and the second pressurizing connecting member 22 can reduce the spacing between the screws through the U-shaped slots at the tail ends of the first pressurizing connecting member and the second pressurizing connecting member.

(9) FIG. 3 is a structure diagram of the opening state of the dual-purpose forceps. When the first opening connecting member 15 on the first forceps body 1 and the second opening connecting member 25 on the second forceps body 2 can be rotated through the articulated shaft 3 freely and the first pressurizing connecting member 14 on the first forceps body 1 is disengaged from the second pressurizing connecting member 24 on the second forceps body 2, the spacing between the screws through the U-shaped slots at the tail ends of the first pressurizing connecting member and the second pressurizing connecting member.

(10) The above description of the disclosed embodiments enables those skilled in the art to achieve or use the dual-purpose forceps. Different kinds of modifications for these embodiments are apparent to those skilled in the art, and general principles defined in this paper can be achieved in other embodiments without separating from the spirit or range of the invention. Thus, the invention is not limited to the embodiments shown in this paper, but needs to meet the widest range which is consistent with the principles and novel features disclosed in this paper.
