When the clamp is designed, the fillet ruler 5 and the pointer 6 can be arranged on the same side of the rear parts of the first clamp rod and the second clamp rod (as shown in figure 2).
As shown in fig. 4, the first forceps lever includes: a first forceps rod body 1; a first handle bar 10 perpendicular to the first jaw body 1 and located at the rear portion thereof for easy gripping; the branch bar, which is connected to the front of the first jaw body 1, has a parallel body 12 parallel to the first jaw body 1. The first measuring foot 3 is hinged with the front end of the first clamp rod body 1, the second measuring foot 4 is hinged with the front end of the parallel rod body 12, and the pointer 6 is hinged with the rear part of the first clamp rod body 1.
In addition, the first forceps rod may further include a pair of vertical rods (as shown in fig. 3, 4, and 1) that fixedly connect two sides of the rear end of the parallel rod 12 and two sides of the first forceps rod 1, respectively, and the pair of vertical rods, the parallel rod 12, and the first forceps rod 1 enclose a cavity for the front end of the second forceps rod to pass through. Alternatively, a vertical plate (not shown) may be used to connect the first clamping bar body 1 and the parallel bar body 12 together, and a through hole for the front end of the second clamping bar to pass through is formed in the middle of the vertical plate. The front end of the second clamp rod passes through the cavity or the through hole and then is hinged with the rear ends of the pair of measuring feet through a hinge shaft, so that the pair of measuring feet can rotate around the hinge shaft to be relatively opened or closed for a certain angle.
It should be noted that, a pair of measurement feet are short-distance opening split-track feet, and are easy to open after entering the external auditory canal. The front ends of the pair of measuring feet (i.e. the ends for measuring the perforation of the tympanic membrane) can be referred to the structure of the tool for measuring the perforation diameter of the tympanic membrane in the prior art, so that the broadsides of the front ends of the pair of measuring feet can be abutted to the edge of the perforated tympanic membrane, and the structure of the front ends is not described in detail herein.
