Description

Le domaine de l'invention de la présente demande est celui de la fixation d'éléments du type clous ou agrafes à l'aide d'un outil à actionnement à main, mais dans un matériau support éloigné de l'opérateur et inaccessible à son outil, même tenu à bout de bras.The field of the invention of the present application is that of fixing nails or staples type elements using a hand-operated tool, but in a carrier material remote from the operator and inaccessible to his tool, even held at arm's length.

La présente invention se rapporte à une perche selon le préambule de la revendication 1.The present invention relates to a pole according to the preamble of claim 1.

Le matériau support qu'on évoque ici est par exemple celui d'un plafond.The support material mentioned here is for example that of a ceiling.

L'outil à actionnement à main qu'on évoque également ici est du genre appareil d'entraînement d'éléments de fixation à tir indirect, avec un piston propulsé vers l'avant sous l'action de la combustion d'une charge de poudre ou de l'explosion d'un mélange de gaz inflammable, pour entraîner un élément de fixation.The hand-operated tool which is also mentioned here is of the indirect firing element type, with a piston propelled forwards by the action of the combustion of a powder charge. or the explosion of a flammable gas mixture to drive a fastener.

L'invention vise à éviter à l'opérateur d'avoir à monter sur une chaise, un escabeau ou autre échelle, pour pouvoir actionner son outil dans de bonnes conditions de stabilité et d'attitude.The invention aims to prevent the operator to have to climb on a chair, a stool or other scale, to be able to operate his tool in good conditions of stability and attitude.

Par actionnement, dans le cas d'un appareil à tir indirect, il faut entendre l'actionnement de la détente de l'appareil.By actuation, in the case of an apparatus with indirect fire, it is meant to operate the trigger of the apparatus.

Par le document US.A.4655380 , on connaît une perche de télé actionnement d'un outil à main comportant, à une extrémité, des moyens de fixation de l'outil, une tringlerie d'actionnement de l'outil, un manchon d'actionnement de l'outil. Mais ce document n'enseigne pas de moyens d'actionnement agencés pour coulisser le long de la perche et pouvant être solidarisés à la tringlerie par des moyens pour solidariser le manchon.. Avec la perche de ce document, la distance de téléactionnement est prédéterminée et non réglable.By the document US.A.4655380 there is known a telescopic pole actuating a hand tool having, at one end, means for fixing the tool, a linkage for actuating the tool, an actuating sleeve of the tool. But this document does not teach actuating means arranged to slide along the pole and can be secured to the linkage by means for securing the sleeve. With the pole of this document, the distance of teleaction is predetermined and not adjustable.

Ainsi l'invention concerne une perche de télé actionnement d'un outil à main selon la revendication 1.Thus, the invention relates to a telescopic boom actuating a hand tool according to claim 1.

De préférence, la clavette de solidarisation est montée pivotante sur le manchon d'actionnement sous l'action de moyens de rappel de cette clavette en position de coincement sur la tringlerie.Preferably, the securing key is pivotally mounted on the actuating sleeve under the action of return means of this key in the jamming position on the linkage.

De préférence toujours, la perche de l'invention est télescopique et comporte au moins deux éléments tubulaires emmanchés l'un dans l'autre, les moyens de fixation de l'outil étant prévus sur l'élément tubulaire intérieur et le manchon d'actionnement, sur l'élément tubulaire extérieur.Preferably still, the pole of the invention is telescopic and comprises at least two tubular elements fitted one in the other, the attachment means of the tool being provided on the inner tubular member and the actuating sleeve, on the outer tubular member.

Dans ce cas, il peut être prévu des manchons de verrouillage de la position relative des deux éléments tubulaires.In this case, there can be provided locking sleeves of the relative position of the two tubular elements.

Alors, il peut être intéressant qu'un premier manchon de verrouillage soit fixé sur l'élément tubulaire extérieur à une extrémité et s'étende le long de l'élément tubulaire intérieur à l'autre extrémité , qui est agencée pour, par vissage et effet de coin avec un deuxième manchon disposé autour de l'élément tubulaire intérieur, être serrée contre l'élément tubulaire intérieur et solidariser ainsi les deux éléments tubulaires en position.Then, it may be interesting that a first locking sleeve is attached to the outer tubular member at one end and extends along the inner tubular member at the other end, which is arranged for, by screwing and wedge effect with a second sleeve disposed around the inner tubular member, be clamped against the inner tubular member and thus secure the two tubular elements in position.

Avantageusement encore, l'extrémité de fixation de la perche d'actionnement est tubulaire, un fourreau de réception de la tringlerie est emmanché par une extrémité dans l'extrémité tubulaire de la perche et un manchon de fixation de l'outil est emmanché sur l'extrémité tubulaire de la perche, l'extrémité tubulaire de la perche, le fourreau et le manchon de fixation étant solidaires en rotation.Advantageously, the fixing end of the actuating pole is tubular, a receiving sheath of the linkage is fitted with one end into the tubular end of the pole and a fixing sleeve of the tool is fitted on the tubular end of the pole, the tubular end of the pole, the sleeve and the fixing sleeve being secured in rotation.

Avantageusement, l'autre extrémité du fourreau est agencée pour coopérer avec un moyeu solidaire de tirants d'écartement de l'outil pour, par un étrier de retenue, créer un effet antagoniste sur ledit outil et ainsi immobiliser l'outil.Advantageously, the other end of the sheath is arranged to cooperate with a hub secured to spacers of the tool to, by a retaining clip, create an antagonistic effect on said tool and thus immobilize the tool.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée de la perche de télé actionnement selon l'invention en référence au dessin annexé sur lequel :

  • la figure 1 représente une vue perspective de l'ensemble de la perche de télé actionnement seule ;
  • la figure 2A est une vue en coupe longitudinale du manchon d'actionnement de l'outil en position de repos;

  • la figure 7 est une vue perspective de cette même extrémité et de l'outil y fixé, en position d'actionnement.
The invention will be better understood with the aid of the following description of a preferred embodiment of the remote control boom according to the invention with reference to the appended drawing in which:
  • the figure 1 represents a perspective view of the entire teleoperating boom alone;
  • the Figure 2A is a longitudinal sectional view of the actuating sleeve of the tool in the rest position;
  • the Figure 2B is a longitudinal sectional view of the actuating sleeve during actuation of the tool;
  • the figure 3 is a cross-sectional view of the actuating sleeve in the rest position;

  • the figure 6 is a side view of the attachment end of the actuating pole and the tool attached thereto, the linkage being in the rest position; and
  • the figure 7 is a perspective view of the same end and the tool attached to it in the actuating position.

En référence à la figure 1, la perche de télé actionnement comporte un élément tubulaire 40 cylindrique creux, une tringlerie 11 s'étendant à l'intérieur de l'élément tubulaire 40 et, en l'extrémité 10 de la perche 1, des moyens de fixation de l'outil 100 à télé - actionner (figures 6 et 7). Un manchon 12 d'actionnement, rendu solidaire de la tringlerie 11 quand on télé - actionne l'outil, coulisse sur ledit élément tubulaire 40 et permet, par l'extrémité 111 de la tringlerie 11, d'actionner la détente 101 de l'outil 100.With reference to the figure 1 , the actuating telescoping pole comprises a hollow cylindrical tubular element 40, a linkage 11 extending inside the tubular element 40 and, at the end 10 of the pole 1, means for fastening the tool 100 to be activated ( figures 6 and 7 ). An actuating sleeve 12, made integral with the linkage 11 when the tool is remotely actuated, slides on said tubular element 40 and allows, by the end 111 of the linkage 11, to actuate the trigger 101 of the tool 100.

Les moyens de fixation de l'outil sont composés d'un étrier en deux parties 21 et 25, s'appuyant sur un manchon 20 de fixation solidaire de l'extrémité 10 de la perche, munies chacune de deux griffes 22, 23 et 26, 27 agencées pour retenir l'outil sous l'action antagoniste d'une poussée l'écartant de l'extrémité 10, exercée par des tirants d'écartement 36, 37, 38, 39 montés sur un moyeu 30, comme expliqué plus loin.The attachment means of the tool are composed of a two-part stirrup 21 and 25, resting on a fastening sleeve 20 secured to the end 10 of the pole, each provided with two claws 22, 23 and 26 , 27 arranged to retain the tool under the counteracting action of a thrust away from the end 10, exerted by spacer rods 36, 37, 38, 39 mounted on a hub 30, as explained below .

Le manchon d'actionnement 12, en référence aux figures 2A, 2B, 3, comporte une clavette 13 de solidarisation pour le solidariser à la tringlerie 11. Ladite clavette, de forme globalement parallélépipédique, est montée pour pivoter autour d'un axe 19 prévu dans le manchon 12. A cet effet, la clavette s'étend à travers deux fenêtres 41, 42 ménagées dans l'élément tubulaire 40, sensiblement symétriques par rapport à l'axe du manchon 12, d'une longueur sensiblement égale à la course du manchon 12 sur le tube 40. La clavette est percée d'un orifice 18, ici cylindrique, permettant le passage avec jeu de la tringlerie 11. Le jeu permet à la clavette de pivoter, mais d'un angle 180 limité par ses bords opposés 181 les plus éloignés. Du fait que la clavette s'étend dans deux fenêtres opposées de l'élément tubulaire 40, tout arc-boutement gênant est évité lors du réglage de la longueur de la perche.The actuating sleeve 12, with reference to Figures 2A , 2B , 3 , comprises a locking key 13 for securing it to the linkage 11. Said key, of generally parallelepipedal shape, is mounted to pivot about an axis 19 provided in the sleeve 12. For this purpose, the key extends through two windows 41, 42 formed in the tubular element 40, substantially symmetrical relative to the axis of the sleeve 12, a length substantially equal to the stroke of the sleeve 12 of the tube 40. The key is pierced with an orifice 18, here cylindrical, allowing the passage with play of the linkage 11. The game allows the key to rotate, but an angle 180 limited by its opposite edges 181 the farthest. Because the key extends in two opposite windows of the tubular member 40, any annoying bridging is avoided when adjusting the length of the pole.

Un piston 14, poussé par un ressort 15 en appui sur une bague 17, est appliqué plus ou moins fortement, ou pas du tout, sur la clavette 13, la bague 17 étant solidaire de l'élément tubulaire 40, ici au moyen d'une goupille 16.A piston 14, pushed by a spring 15 bearing on a ring 17, is applied more or less strongly, or not at all, on the key 13, the ring 17 being integral with the tubular element 40, here by means of a pin 16.

Alors que sur la figure 2A, la clavette 13 n'est pas inclinée de l'angle 180 et que par conséquent la tringlerie est libre de coulisser dans l'orifice 18, sur la figure 2B, le manchon d'actionnement 12 peut être sollicité manuellement vers le bas en compressant le ressort 15, ce qui entraîne que, sous l'action du ressort 15 et du piston 14, la clavette 13 pivote et coince la tringlerie par les bords 181 de son orifice 18, ce qui la solidarise au manchon 12. A l'inverse, le manchon 12 est rappelé vers le haut par un dispositif présenté plus loin.While on the Figure 2A , the key 13 is not inclined at the angle 180 and that consequently the linkage is free to slide in the orifice 18, on the Figure 2B , the actuating sleeve 12 can be manually biased downwardly by compressing the spring 15, resulting that, under the action of the spring 15 and the piston 14, the key 13 pivots and jams the linkage by the edges 181 of its orifice 18, which secures it to the sleeve 12. In contrast, the sleeve 12 is biased upwards by a device shown below.

La perche de télé actionnement est prévue pour être télescopique et comporter un autre élément tubulaire 50, ici intérieur, et coulissant dans l'élément tubulaire extérieur 40, et pouvant y être fixé en fonction de la longueur d'emmanchement souhaitée.The tele actuating boom is intended to be telescopic and include another tubular element 50, here inner, and sliding in the outer tubular element 40, and can be fixed there depending on the desired fitting length.

La bague 17 et le piston 14 laissant un passage libre à la tringlerie 11, prévue de longueur suffisante, la solidarisation de la tringlerie 11 au manchon d'actionnement 12 peut être réalisée en une zone de ladite tringlerie qui correspond à cette longueur d'emmanchement.The ring 17 and the piston 14 leaving a free passage to the linkage 11, provided of sufficient length, the fastening of the linkage 11 to the actuating sleeve 12 can be made in an area of said linkage which corresponds to this fitting length .

Pour régler la longueur d'emmanchement souhaitée, en référence à la figure 4, l'élément tubulaire extérieur 40 comporte un manchon 60 de verrouillage, qui lui est solidaire en son extrémité la plus éloignée de l'extrémité 10 de la perche, grâce à une goupille 62, et l'élément tubulaire intérieur 50 comporte un manchon de verrouillage 70, monté coulissant sur l'élément tubulaire 50.To adjust the desired fitting length, with reference to the figure 4 , the outer tubular element 40 comprises a locking sleeve 60, which is secured to its end farthest from the end 10 of the pole, by means of a pin 62, and the inner tubular element 50 comprises a sleeve of latch 70, slidably mounted on the tubular element 50.

Les manchons de verrouillage 60 et 70 coopèrent pour solidariser les éléments tubulaires 40 et 50 entre eux en une zone quelconque de l'élément tubulaire 50 de la façon suivante :

  • le manchon de verrouillage 70 comporte un alésage axial taraudé 72 pouvant se visser sur une partie cylindrique externe filetée 63 du manchon de verrouillage 60,
  • le manchon de verrouillage 70 comporte un alésage conique axial 71 en deçà de l'alésage taraudé 72 et le manchon de verrouillage 60 comporte, au-delà de sa partie cylindrique externe filetée 63, une jupe fendue 64 s'étendant le long de l'élément tubulaire intérieur 50 et se terminant par une surface conique agencée pour épouser l'alésage conique 71 du manchon 70, présentant une certaine élasticité, et assurer ainsi un effet de coin,
  • quand on visse le manchon de verrouillage 70 sur le manchon de verrouillage 60 à l'endroit choisi de l'élément tubulaire 50, les languettes de fixation de la jupe 64, entre les fentes, sont serrées sur ledit élément tubulaire par l'alésage conique 71, ce qui, par effet de coin, solidarise l'élément tubulaire interne 50 au manchon de verrouillage 60 donc à l'élément tubulaire externe 40 en position relative par rapport à celui-ci.
The locking sleeves 60 and 70 cooperate to secure the tubular elements 40 and 50 together at any zone of the tubular element 50 as follows:
  • the locking sleeve 70 has a tapped axial bore 72 which can be screwed onto a threaded outer cylindrical portion 63 of the locking sleeve 60,
  • the locking sleeve 70 has an axial conical bore 71 below the threaded bore 72 and the locking sleeve 60 has, beyond its threaded outer cylindrical portion 63, a slotted skirt 64 extending along the inner tubular element 50 and ending in a conical surface arranged to fit the conical bore 71 of the sleeve 70, having a certain elasticity, and thus to provide a wedge effect,
  • when the locking sleeve 70 is screwed onto the locking sleeve 60 at the chosen location of the tubular member 50, the fastening tabs of the skirt 64 between the slots are clamped to said tubular member by the tapered bore 71, which, by wedge effect, secures the inner tubular member 50 to the locking sleeve 60 and the outer tubular member 40 in relative position relative thereto.

Autour de l'élément tubulaire 50, on a inséré un ressort 90 de protection entre le manchon de verrouillage 70 et le manchon de fixation 20, de sorte que lors du desserrage des languettes de la jupe 64, lesdits manchons ne viennent pas brutalement en butée l'un contre l'autre et ne risquent pas de blesser l'utilisateur.Around the tubular element 50, a protective spring 90 is inserted between the locking sleeve 70 and the fixing sleeve 20, so that, when the tongues of the skirt 64 are loosened, said sleeves do not come abruptly in abutment. against each other and are not likely to injure the user.

Les moyens de fixation de l'outil 100 à l'extrémité 10 de la perche 1 vont maintenant être présentés en référence aux figures 5 et 6.The attachment means of the tool 100 at the end 10 of the pole 1 will now be presented with reference to the figures 5 and 6 .

Le manchon de fixation 20 est fixé à l'extrémité supérieure de l'élément tubulaire interne 50, qui est l'extrémité 10 de la perche, et dans laquelle est emmanchée l'extrémité 81 d'un fourreau 80 de réception de la tringlerie 11. L'extrémité tubulaire de la perche (le tube interne 50), le fourreau 80 et le manchon de fixation 20 sont solidarisés par une goupille 91.The fixing sleeve 20 is fixed to the upper end of the inner tubular element 50, which is the end 10 of the pole, and in which is fitted the end 81 of a sheath 80 for receiving the linkage 11 The tubular end of the pole (the inner tube 50), the sleeve 80 and the fixing sleeve 20 are secured by a pin 91.

L'autre extrémité 82 du fourreau 80 comporte un filetage sur lequel est vissée la bague de blocage 31 d'un moyeu 30, le taraudage de la bague étant « à gauche ». Le moyeu 30 est solidaire de tirants d'écartement, dans l'exemple ici considéré, au nombre de quatre, 36, 37, 38, 39, régulièrement disposés et comportant en leur extrémité libre des doigts 360, 370, 380, 390 cylindriques agencés pour pouvoir être mis en appui sur des surfaces 110 de la structure arrière de l'outil 100.The other end 82 of the sleeve 80 has a thread on which is screwed the locking ring 31 of a hub 30, the tapping of the ring being "left". The hub 30 is secured to spacers, in the example here considered, four in number, 36, 37, 38, 39, regularly arranged and having at their free end of the fingers 360, 370, 380, 390 arranged cylindrical to be able to bear on surfaces 110 of the rear structure of the tool 100.

En sa partie médiane, le fourreau 80 comporte une collerette 84 agencée pour coopérer avec le manchon 20 de fixation pour maintenir un étrier comportant deux parties, une mâle 25 et une femelle 21, séparables mais agencées pour s'assembler l'une dans l'autre par des semelles mâle 29 et femelle 28 lorsqu'elles s'emboîtent entre la collerette 84 et le manchon 20 sur le fourreau 80.In its middle part, the sheath 80 comprises a flange 84 arranged to cooperate with the fixing sleeve 20 to maintain a stirrup comprising two parts, a male 25 and a female 21, separable but arranged to assemble one into the other. other by male soles 29 and female 28 when they fit between the flange 84 and the sleeve 20 on the sheath 80.

Quand l'outil 100 est en place dans l'étrier, les parties d'étrier 21 et 25 s'étendent au delà de la structure arrière de l'outil 100 jusqu'à une conformation de ladite structure présentant des surfaces 112 en creux à concavité orientée vers l'avant_et sur lesquelles des griffes 22, 23, 26, 27 desdites parties d'étrier 21 et 25 peuvent prendre appui et s'encastrer dans les creux de ces surfaces 112.When the tool 100 is in place in the stirrup, the stirrup portions 21 and 25 extend beyond the rear structure of the tool 100 to a conformation of said structure having surfaces 112 hollow to concavity oriented forward and on which claws 22, 23, 26, 27 of said stirrup portions 21 and 25 can bear and fit into the recesses of these surfaces 112.

De plus, un doigt 390 du tirant 39 traverse une patte 251 de la partie 25 de l'étrier (voir figures 1 et 5) de sorte que lorsqu'on fait tourner l'étrier autour de la perche, les tirants d'écartement 36, 37, 38, 39 tournent également autour de la perche et entraînent le moyeu 30 dans cette rotation, moyeu qui se visse alors sur le fourreau 80.In addition, a finger 390 of the tie rod 39 passes through a tab 251 of the part 25 of the stirrup (see figures 1 and 5 ) so that when the stirrup is rotated around the pole, the spacing rods 36, 37, 38, 39 also rotate around the pole and drive the hub 30 in this rotation, which hub then screws on the sheath 80.

De même, la tringlerie 11 est entraînée dans cette rotation par des pattes 211 et 212 (voir figure 7) solidaires de la partie 21 de l'étrier. Il en résulte qu'en serrant l'outil 100 entre l'étrier et les tirants d'écartement, l'outil, les parties 21 et 25 de l'étrier, les tirants d'écartement 36, 37, 38, 39, le moyeu 30, et la tringlerie 11 restent solidaires en rotation.Similarly, the linkage 11 is driven in this rotation by legs 211 and 212 (see figure 7 ) integral with the part 21 of the stirrup. As a result, by tightening the tool 100 between the stirrup and the spacer rods, the tool, the parts 21 and 25 of the stirrup, the spacing rods 36, 37, 38, 39, the hub 30, and linkage 11 remain integral in rotation.

Enfin, la tringlerie 11 comporte un piston 9 coulissant dans l'extrémité 82 du fourreau 80 et soumis à une force de rappel exercée par un ressort 83.Finally, the linkage 11 comprises a piston 9 sliding in the end 82 of the sleeve 80 and subjected to a restoring force exerted by a spring 83.

Pour mettre en place l'outil entre les deux parties 21 et 25 de l'étrier, il faut les écarter l'une de l'autre transversalement à la perche en faisant coulisser leurs semelles mâle 29 et femelle 28 l'une dans l'autre, placer la structure arrière de l'outil entre leurs griffes 22, 23, 26, 27 puis rapprocher ces deux parties dans le mouvement inverse pour mettre leurs griffes en face des surfaces 112.To set up the tool between the two parts 21 and 25 of the stirrup, it is necessary to separate them from one another transversely to the pole by sliding their soles male 29 and female 28 one in the other, place the rear structure of the tool between their claws 22, 23, 26, 27 then bring these two parts in the opposite movement to put their claws in front of the surfaces 112.

Pour le serrage de l'outil 100 entre les griffes de l'étrier 22, 23, 26, 27 et les doigts 360, 370, 380, 390 des tirants d'écartement 36, 37, 38, 39, on le tourne autour de la perche 1, ou on visse le manchon de fixation 20 de la perche autour de l'ensemble étrier et outil. Ce faisant, cet ensemble étant solidaire en rotation du moyeu 30, ce dernier se visse autour du fourreau 80. Le filetage du fourreau et de la bague 31 étant à gauche, les doigts 360, 370, 380, 390 s'écartent de l'extrémité 10 de la perche, puis écartent, en s'appuyant sur les surfaces 110 de la structure arrière de l'outil 100, l'outil lui-même de la perche, et appliquent les surfaces 112 contre les griffes 22, 23, 26, 27 de l'étrier. Par effet antagoniste dû à l'étrier, les semelles 28, 29 exercent une traction sur la collerette 84 du fourreau 80, ce qui les solidarise au fourreau 80, donc à l'extrémité 10 de la perche 1.For the clamping of the tool 100 between the claws of the stirrup 22, 23, 26, 27 and the fingers 360, 370, 380, 390 of the spacer rods 36, 37, 38, 39, it is rotated around the pole 1, or we screw the fixing sleeve 20 of the boom around the caliper and tool assembly. In doing so, this assembly being integral in rotation with the hub 30, the latter is screwed around the sleeve 80. The thread of the sleeve and the ring 31 being on the left, the fingers 360, 370, 380, 390 deviate from the end 10 of the pole, then spread, relying on the surfaces 110 of the rear structure of the tool 100, the tool itself of the pole, and apply the surfaces 112 against the claws 22, 23, 26 , 27 of the stirrup. By antagonistic effect due to the stirrup, the soles 28, 29 exert traction on the flange 84 of the sheath 80, which secures them to the sleeve 80, thus to the end 10 of the pole 1.

Pour actionner l'outil, on actionne le manchon d'actionnement 12 vers le bas (si l'outil doit être présenté vers le haut), lequel comprime le ressort 15 par l'intermédiaire du piston 14. Le piston 15 repousse et fait pivoter la clavette 13 dans une position de solidarisation (181) de la tringlerie 11. Par suite, la tringlerie est tirée vers le bas, et actionne la détente 101 de l'outil grâce à un bec terminal 111. En même temps, par l'intermédiaire du piston 9, la tringlerie 11 comprime le ressort 83.To actuate the tool, the actuating sleeve 12 is actuated downwards (if the tool must be presented upwards), which compresses the spring 15 via the piston 14. The piston 15 pushes and rotates the key 13 in a securing position (181) of the linkage 11. As a result, the linkage is pulled down, and actuates the trigger 101 of the tool through a terminal nozzle 111. At the same time, by the intermediate piston 9, the linkage 11 compresses the spring 83.

Après actionnement de l'outil, on relâche le manchon d'actionnement 12, le ressort 83 repousse le piston 9, ce qui a pour effet de tirer la tringlerie 11 vers le haut (toujours dans l'hypothèse d'une action de l'outil vers le haut), d'écarter le bec terminal 111 de la détente 101 et de désolidariser ladite tringlerie du manchon d'actionnement 12, lequel, sous l'action du ressort 15, du piston 14, et de la clavette 13, revient à sa position de repos, c'est-à-dire avant actionnement.After actuation of the tool, it releases the actuating sleeve 12, the spring 83 pushes the piston 9, which has the effect of pulling the linkage 11 upwards (always in the event of an action of the tool upwards), to separate the terminal nozzle 111 from the trigger 101 and to disengage said linkage from the actuating sleeve 12, which, under the action of the spring 15, the piston 14, and the key 13, returns at its rest position, that is to say before actuation.
