Definitions

  • the applicant has detected the problem and his diagnosis is that he is found in the lug, which is positioned inappropriately in the gear.
  • the applicant has found that the longitudinal stroke of the lug is excessive from the moment the jaws of the pincers touch the workpiece until the teeth mesh and the final fixation of the part takes place, what is at the origin of the difficulties mentioned of seizure-fixing of the part.
  • Applicant solved the problem with an additional spring which allows the lug to pivot quickly from the moment the jaws come into contact with the workpiece and, therefore, decrease the longitudinal stroke.
  • the pincers consist, as is known, of a male arm (6) with a head (7) with the upper toothed jaw (10) in which a window (8) has been made with teeth (9) and a female arm (11) having a large opening, which allows the passage of the head (7) of the male arm (6) and which carries the toothed jaw (13) lower and a lug (14) toothed element which pivots and meshes with the teeth (9) of window (8).
  • male arm (6) and the female arm (11) are united by a connecting rod (15) which pivots at its ends on the male and female arms (6), (11) and with a inner spring (3).
  • the spring (5) tends to keep the male-female arms (6), (11) open.
  • the lug (14) has front teeth (17) which must mesh with the teeth (9) of the head (7) of the male arm (6).
  • the spring (5) tends to bring the posterior surface (30) into contact of the lug (14) with the surface (31) of the window (8) facing the teeth (9) (figures 2 and 3).
  • the jaws (10), (13) of the pincers must grip the part (20) to work so that the user only has to tighten the male and female arms (6), (11). At when the jaws (10), (13) come into contact with the workpiece, we found in the position of figure 2.
  • the linear component 0 1 0 ' 1 is guilty of the fact that the teeth (17) of the lug (14) mesh with the teeth (9) which immediately follow those corresponding to them which face them.
  • this additional spring (m) is continuous, but it is not observed until the jaws (10) (13) are in contact with the part (20) and the hand of the user has overcome the action of the spring (5) which tends to put the lug (14) in a rest position - non-meshing.
  • the additional spring (m) tends to pivot the lug (14) on its center of rotation (0 1 ), which is added to the conventional action of the user who tightens the arms (6 ), (11), which is at the origin of the following cause-effect chain: the low rotation ( ⁇ ) 0 " 1 0 3 is very quickly obtained; the consequence is a linear component 0 1 0" 1 very small; hence a rapid meshing, as a result of which the teeth (17-1), (17-2), (17-3) of the lug (14) mesh with their corresponding teeth facing them (9 1 -1), (9-2), (9-3) of the head (7).
  • the spring (m) is installed by compression, preferably in a perforation of the lug (14) practiced in its rear part, in an area as far as possible from the center of rotation (0 1 ) and of action against the surface (31) of the window facing the teeth (9).
