SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a jaw head of a pair of tongs for preventing the alimentary canal from being scratched so as to solve the problems in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a prevent jaw pincers binding clip of disappearance way fish tail, is the tong arm that is the scattering form and distributes between a plurality of left ends, sets up the annular coupler body of inside bending at the tong arm left end, cup joints the soft sleeve pipe of tong arm right-hand member and is located the intraductal seal wire of fixing at the tong arm right-hand member of cover.

Still including cup jointing the elastic lag of the loudspeaker form on the tong arm, and leave between tong arm and the sleeve pipe and supply the lag shrink back male clearance, the lag can separate the tong arm in order to avoid fish tail antrum stomach and esophagus when the tong arm is retrieved.

Preferably, the protective sleeve is an elastic rubber film.

Preferably, the left end of the protective sleeve extends inwards to form an extension part fixed on the hook body.

Preferably, the extension extends with a cylindrical protrusion that can be inserted into the hook body.

Preferably, the joint of the extension part and the protective sleeve is in circular arc transition.

Preferably, the protecting sleeve is connected with the forceps arms in a bonding mode through glue.

Preferably, a chamfer convenient for inserting the sleeve is arranged at the right end of the protecting sleeve in the circumferential direction.

Compared with the prior art, the utility model has the beneficial effects that:

1. the elastic protective sleeve is arranged on the forceps arm, the protective sleeve can isolate the forceps arm in the process of pulling back, and the protective sleeve is smooth and soft, so that the esophagus or the antrum of the stomach can be well protected;

2. the extension that the tip of lag set up has increased fixed area, and the arch is then the block to be fixed in the hook body, and fixed more durable.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 6, the present invention provides a technical solution of a claw head for preventing a chemical tract scratch: a claw tong head for preventing and eliminating scratches of a road comprises a plurality of tong arms 1 distributed in a scattering shape between the left ends, an annular hook body 11 arranged at the left end of each tong arm 1 and bent inwards, a soft sleeve 12 sleeved at the right end of each tong arm 1, and a guide wire 13 positioned in the sleeve 12 and fixed at the right end of each tong arm 1. An operating handle for pulling the forceps arm 1 is arranged between the end of the guide wire 13 and the sleeve 12, which is prior art and will not be described in detail.

Still including cup jointing the elastic lag 2 of the loudspeaker form on tong arm 1, and leave between tong arm 1 and the sleeve pipe 12 and supply lag 2 male clearance after the shrink, lag 2 can separate tong arm 1 in order to avoid fish tail antrum stomach and esophagus when tong arm 1 retrieves. The protective cover 2 is an elastic rubber film. Lag 2 here adopts the rubber membrane, and mainly toughness is good, and the contractility is good, is convenient for accomodate into sleeve pipe 12, and sleeve pipe 12 diameter is at 2mm to 3mm after all, in addition, does not adopt the umbrella cloth material here, mainly considers the contractility. Tong arm 1 is then the metal, has toughness, when accomodating, tends to the straight line, just because adopt the metal, when intensity is good, has the risk of fish tail esophagus and stomach sinus. It should be noted that the present invention is not limited to the storage of the forceps arms 1, but is also applicable to the flip-grip type, such as a biopsy forceps.

The left end of the protective sleeve 2 extends inwards to form an extension part 21 fixed on the hook body 11. The contact area is increased, the fixing effect is better, and meanwhile, when the fixing device is inserted, the protection of the left end is formed. The extension 21 is extended with a cylindrical protrusion 22 that can be inserted into the hook body 11. The protrusion 22 can be engaged in the hole of the hook body 11, and the fixing effect is good. The junction of the extension 21 and the protective sleeve 2 is in circular arc transition. The edges and corners are avoided, the process is smoother, and friction is reduced. The protective sleeve 2 is connected with the clamp arm 1 through glue in a bonding mode. The fixing is convenient and the fixing area is large. The right-hand member circumference of lag 2 is provided with the chamfer of conveniently inserting sleeve pipe 12. Is convenient to store and avoids being blocked.

The working principle is as follows: be provided with elastic lag 2 on tong arm 1, at the in-process of pulling back, tong arm 1 can be kept apart to lag 2, and lag 2 itself is more smooth, and is more soft again, consequently, protection esophagus or antrum of stomach that can be fine. The extension part 21 arranged at the end part of the protective sleeve 2 increases the fixing area, and the protrusion 22 is clamped and fixed in the hook body 11, so that the fixing is firmer.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
