  The present invention will now be described at

  For example, in connection with the accompanying drawings.

  In one embodiment, an outer rod 1 has a seat 3 for a securing ring 2 which has

  a predetermined length from its posterior end

  re and has a large diameter throughout its length. A

  circumferential groove 4 is provided on the inner surface

  seat 3 near the front end; to a party

  in front of the circumferential groove 4 is formed a rim-

  8 type L-shaped cam member which consists of a longitudinal groove

  tudinal 6 in the axial direction and a transverse groove 7

  in the circumferential direction (FIGS. 5 and 6).

  longitudinal re 6 has an open posterior end 5.

  at a front step 5 of the seat 3, and the transverse groove 7-

  is made along a front step 5 of the seat 3 in the circumferential direction, where the two grooves 6 and 7 are

  connected to each other at the posterior end of the reason-

  longitudinal section 6 so as to form an L. On the other hand, the securing ring 2 which is

  consisting of an insertion rod 10 and a rim 11 is shown

  inside the seat 3 of the outer rod so

  to be able to turn and not be able to move

  in the axial direction. The rim 11 is formed on the surface

  this outside of the ring 2 at a place located at the back of

  the anterior end of the insertion rod at a specific distance

  specific, and a multitude of longitudinal grooves 12 are formed at specific locations on the inner surface of the

the ring 2.

  In addition, on a percussion cylinder 15 which is

  open at its anterior extremity and closed at its extremity

  and has a diameter slightly smaller than the diameter

  inside the ring 2, a projection 13 and a multitude of ribs 14 are provided. Each rib 14 is formed at a location corresponding to the longitudinal groove 12 on the same length.

  The percussion cylinder is inserted into the ring of

  2 and the outer rod 1 so that the projection 13 can be in sliding contact with the cam groove 8 of the outer rod 1, and the rear portion of the cylinder of

  percussion 15 may be beyond a surface of the ring-2.

  The percussion cylinder 15 is received in the outer rod 1, a spiral spring 17 being held in its interior, so that the front end of the cylinder

  can be attached to the posterior end of the inner shaft.

  16. The spiral spring is weaker than the percussion spring (not shown) without affecting the movement of the

inner shaft 16.

  In the state where the applicator is running, the

  13 of the percussion cylinder 15 is placed in a groove 6.

  6 of the cam groove 8 formed in the outer rod

  in the out-of-service position, the projection 13 is placed

  in place B of FIG. 5 and can be brought to the location where the front limit is located (FIG. 2). Thus, a percussion operation is performed by slidably moving the sail 13 along the longitudinal groove 6 of the groove

cam 8.

  When the applicator is not in use, the percussion cylinder 15 is rotated to operate without percussion. The percussion cylinder can not rotate relative to the securing ring 2; however, the cylinder can be rotated simultaneously with the ring 2 relative to the outer rod 1 because the ring 2 can slide by

  relative to this rod by displacement of the flange 11 in the groove

  circumferential re 4 of the outer rod 1. At the same time, the projection 13 of the percussion cylinder 15 is moved in the transverse groove 7 along the cam groove 8 of the rod

  exterior. The projection 13 can reach the position C in FIG.

  5. This is a state in which the percussion cylinder

  sion is anchored (Figure 1). If we hit the percussion cylinder

  at this stage, a percussion operation can not take place

  because the protrusion 13 abuts against a side wall of the groove

  crosswise 7. Note that the spiral spring 17

  is intended to prevent the play of the percussion cylinder in the

  external geometry and has nothing to do with the percussion function

according to the present invention.

  In another embodiment (hereinafter referred to as a second embodiment), the projection 13 may be formed on the ring 2 and not on the percussion cylinder 15. By

  therefore, a cam groove 8 consisting of a transom groove

  7, and a longitudinal groove 6 can be formed on

  the outer surface of the percussion cylinder near the former

  anterior tremity. In order to lock a percussion means, a longitudinal groove 6 'of short length may be formed which is interconnected with the groove 7.

  at the end opposite to the longitudinal groove

  6 (Figure 9). The securing ring 2, the percussion cylinder 15 and the inner rod can be assembled

  in a similar way to that described above.

  In the second embodiment, the projection 13 of

  the ring 2 is placed in a zone of the longitudinal groove

  6 in the cam groove 8 when the applicator is in use. When the percussion cylinder abuts against the percussion spring, the projection 13 can be displaced by

  position A at a position B o is a front limit (fig.

  re 9). After release of the percussion force, the projection is returned to the position A as a result of the elasticity of the spring

of percussion.

  If the applicator is not used,

  cussion must be protected. Therefore, we turn the cylinder

  percussion so that the protrusion 13 can be

  born in the transverse groove 7 of the cam groove 8. In this situation, a percussion operation can not take place because the projection 13 abuts against a side wall of the groove

  7. If we turn the cylinder of percussion a little more

  in order to reach the position C, the projection 13 moves in the longitudinal groove 6 'of short length to be pushed to a position D under the effect of the spring

  spiral 17. This is a state where the percussion cylinder

  sion is anchored. When using the applicator from

  the anchored state, the percussion cylinder should be slightly

  so that the projection 13 can be brought from the position D to the position C. However, as the distance of such a recoil

  is quite short, and is within the limits of the game of

  9, the distance does not suffer from an action of

cussion.

  In yet another embodiment (hereinafter

  after the third mode), the projection 13 may be formed on the percussion cylinder 15 or on the inner rod 16, and

  a cam groove 8 may be provided in the interior surface

  1 of the outer rod 1 and the securing ring 2. The cam groove 8 consists of a longitudinal groove 6 on the inner surface of the rod

  1 having the same length as the

  and a step groove consisting of a transverse groove

  7, a longitudinal groove 6 "and another groove

  crosswise 7 '. The posterior end of the longitudinal groove

  tudinal 6 of the outer rod 1 is connected to the end of

  the transverse groove 7 of the ring 2 so that the groove

  The cam follower 8 may have a stepped shape as a whole.

  The projection 13 of the percussion cylinder or the inner rod

  re 16 is engaged by sliding in the groove 8.

  The means of percussion of the third mode of

  It is assembled so that the inner rod 16, the spiral spring 17 and the percussion cylinder 15 are introduced in this order into the outer rod 1. After engagement of the

  projection 13 of the percussion cylinder 15 in the longitudinal groove

  6 of the rod 1, the securing ring 2 is mounted

  of force so as to connect the end of the trans-

  versale 7 of the ring 2 at the rear end of the groove

  longitudinal 6, o the completion of the groove 8 in step.

  A percussion operation occurs by moving

  the projection 13 of the percussion cylinder in the longitudinal groove

  6 between position D and position E of FIG.

  The position E is a limit before the percussion operation,

  while the position D is a rear limit.

  When the applicator is not in use, the percussion cylinder 15 is rotated so as to bring the projection 13

in the transverse groove 7.

  In this state, a percussion action is prevented except to turn the percussion cylinder. In order to prevent further percussion movement, the cylinder is still rotated

  percussion so as to bring the projection 13 to the other ex-

  tremity, position C, of the transverse groove 7, operation

  which is followed by the arrival in the longitudinal groove 6 ".

  After subsequent movement of the projection 13 towards the B position of the posterior end under the effect of the force of the spiral spring 17 etc., the percussion cylinder is rotated again to bring the projection 13 position A of

  the transverse groove 7 'and anchor it. Thus, the double lock

  the percussion means is completed. In the third embodiment, the groove

  cam 8 may alternatively be formed so that the longitudinal groove

  6 "and / or the transverse groove 7 'are formed either on the outer rod 1 or on the securing ring 2 unless the longitudinal groove 6 and the transverse groove 7 are formed on the inner surfaces of the rod 1 and the ring 2, respectively, For example, the transverse groove 7 'can be formed along

  of the stepped part of the outer rod 1.

  The present invention is not limited to the examples

  described above, it is, on the contrary,

  re susceptible to modifications and variants that will appear

to the man of the art.
