H1546 iH1546 i

Opfindelsen angår et sugeredskab af den i kravets Indledning anførte art til fjernelse eller løftning og bortføring af små mængder af partikelformede, flydende eller smeltede emner ved 5 hjælp af luftsugeteknik og nærmere betegnet et håndbetjent vakuumslagrenseorgan, der kan holdes i hånden.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a suction tool of the kind set forth in the preamble of claim 1 for the removal or lifting and removal of small amounts of particulate, liquid or molten articles by means of air suction technique and more particularly, a hand operated vacuum cleaning means which can be held by hand.

Opfindelsen finder især anvendelse inden for området lodning, fralodning og omtrådning i elektroniske laboratorier, reparationsforretninger, fabrikker eller 10 på hobbymandens arbejdsbord, og selv om meget af den efterfølgende beskrivelse af eksempler på opfindelsen for klarheds og kortheds skyld er rettet imod dette felt, må det forstås, at fordelene ved opfindelsen lige vel manifesterer sig på andre områder, hvor 15 substanser skal fjernes eller renses bort fra en genstand, som f.eks. inden for det medicinske eller dentale område til fjernelse af fremmede objekter eller uønskede substanser fra dele af legemet såsom øjet, øret, næsen, halsen eller et åbent sår.The invention is particularly applicable in the field of soldering, stripping and retreading in electronic laboratories, repair shops, factories or 10 on the hobbyist's desk, and although much of the following description of examples of the invention is directed to this field for clarity and brevity, it must It is understood that the advantages of the invention manifest themselves in other areas where substances are to be removed or purified from an object such as e.g. in the medical or dental field for removing foreign objects or unwanted substances from parts of the body such as the eye, ear, nose, throat or open wound.

20 Inden for elektroteknikken ønsker man som nævnt ofte at fralodde en elektrisk forbindelse som f.eks. en trådomsnoet terminal eller en tråd til et kredsløbspladeøsken. Fjernelsen af det smeltede loddemateriale fra forbindelsen uden at dryp-25 pe eller sprøjte det på andre dele af udstyret er almindeligvis væsentlig. Bortblæsning eller -rystning af det smeltede metal er derfor ikke en acceptabel praksis, og i forbindelse med dets høje vægtfylde gør loddematerialets store overfladespænding 30 fjernelse af det særligt vanskeligt. Endvidere uddybes problemet ved kravet om, at loddematerialet skal fjernes hurtigt og uden påføring af kølemidler, før den mekaniske forbindelse, såsom en trådomsnoet terminal kan adskilles.20 As mentioned above, in electrical engineering, it is often desirable to disconnect an electrical connection, such as for example. a wire wrapped terminal or a wire for a circuit board case. The removal of the molten solder from the compound without dripping or spraying it on other parts of the equipment is generally essential. Blasting or shaking of the molten metal is therefore not an acceptable practice, and in connection with its high density, the high surface tension of the solder makes removal of it particularly difficult. Furthermore, the problem is compounded by the requirement that the solder be removed quickly and without the application of refrigerants before the mechanical connection, such as a wirewound terminal, can be separated.

35 Et sugeredskab af den indlednings vis nævnte art er omhandlet i USA-patentskrift 2 141546 nr. 3.263.889, ved hvilket redskab spændeskedens bevægelse er styret i slidser i et bageste endedæksel i cylinderen, idet dens forreste del under spænding af spændefjederen ligger an imod et fremspring på 5 stemplet. Denne konstruktion har i praksis vist sig at give anledning til funktioneringsvanskeligheder, idet spændeskeden under dens returbevægelse er tilbøjelig til at komme i klemme i slidserne og derved forhindrer eller vanskeliggør stemplets tilbageføring 10 således, at værktøjet ikke kan anvendes efter sin hensigt.35 A suction tool of the kind mentioned in the preamble is disclosed in United States Patent 2 141546 No. 3,263,889, in which the tool of the clamping spoon is guided in slots in a rear end cover of the cylinder, its front part under tension of the clamping spring abutting a projection of 5 stamped. In practice, this construction has been found to cause difficulties in functioning, since the clamping sheath during its return movement tends to become trapped in the slots thereby preventing or impeding the return of the piston 10 so that the tool cannot be used in its intended purpose.

Formålet nted den foreliggende opfindelse er at tilvejebringe et sugeredskab, som ikke frembyder den ovennævnte ulempe, og hvor spændeskeden ik-15 ke er tilbøjelig til at komme i klemme i sine føringer.The object of the present invention is to provide a suction tool which does not present the disadvantage mentioned above and in which the clamping spoon is not likely to get caught in its guides.

Dette opnås ifølge opfindelsen ved, at sugeredskabet er indrettet som angivet i kravets kendetegnende del.This is achieved according to the invention in that the suction tool is arranged as indicated in the characterizing part of the claim.

Idet spændeskedens bageste endedel under spæn-20 dingen af spændefjederen virker direkte mod stempelstangen undgår man, at spændeskeden over sin længde skal overføre trykkræfter, der kunne give anledning til deformation af spændeskeden. Sammen med den omstændighed, at parallelføringen af spændeskeden sker 25 ved hjælp af holde-styredele, der er ført aksialt forskydelige i slidser mellem huset og en på dette anbragt ydre beklædningsdel, bevirker dette forhold, at spændeskeden hverken under sin frem- eller tilbagegående bevægelse er tilbøjelig til at komme i klemme 30 i føringerne, men bestandig føres i en akseparallel beværelse.As the trailing end portion of the clamping shaft under the tension of the clamping spring acts directly against the piston rod, it is avoided that the clamping sheath over its length must transmit compressive forces which could cause deformation of the clamping sheath. Coupled with the fact that the parallel movement of the clamping spoon is effected by means of holding guide members which are axially slidable in slots between the housing and an outer cladding part, this condition causes the clamping spout to be neither in its reciprocating or reciprocating motion. prone to clamp 30 in the guides, but is always guided in axis parallel motion.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken fig. 1 viser i perspektiv et sugeredskab 35 ifølge opfindelsen i ikke spændt eller ikke ladt tilstand.The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 is a perspective view of a suction tool 35 according to the invention in an unstressed or unstressed state.

Sugeredskabet 10 i fig. 1 har et cylindrisk hus 12, der har en åben forreste ende 14 og en i hovedsagen . lukket ende 16, der som glideleje bærer etempelstangen.The suction tool 10 in FIG. 1 has a cylindrical housing 12 having an open front end 14 and one in the main case. closed end 16 which, as a sliding bearing, carries the template rod.

2ø En aftrækkerenhed 18, der samvirker med stempel stangen r bæres af huset 12's bageste ende 16.A trigger unit 18 cooperating with the piston rod r is supported by the rear end 16 of the housing 12.

En vakuumcylinder 20 bæres af og er delvis indeholdt i huset 12. I den viste udførelsesform er cylinderen 20 støbt af et stift, gennemsigtigt 25 formstof til synliggørelse af dens indre med henblik på inspektion. En spids- og mundetykkeenhed 22, 24 bares aftageligt af cylinderen 20's forreste ende 26.A vacuum cylinder 20 is supported and partially contained within the housing 12. In the embodiment shown, the cylinder 20 is molded from a rigid, transparent plastic material to make its interior visible for inspection. A tip and nozzle assembly 22, 24 is removably supported by the front end 26 of the cylinder 20.

En spandeskede 28 bæres også af huset 12 og 30 har et par holdestyredele 30, 32, der strækker sig fremad aksialt forskydeligt i holdekanaler, der er vist i senere figurer, i huset 12. Den bageste endedel 34 af spændeskeden er i hovedsagen lukket og er udformet til at indeholde en amboltoverflade 36, 35 der berører en spændestang. En spændéskedetilbage- føringsfjeder 38 holdes aksialt sammefttrykkelig i spæn-' deskeden mellem endedelen 34 og den bfigeste ende 16 4 141546 af huset 12. Hver af holdestyredelene 30, 32, er forsynet med en låseåbning 40, der samvirker med et låsefremspring, der er vist i senere figurer, og som bæres på den indre overflade af hver af et par bøje-5 lige låsefaner 44, der bæres af den bageste ende af huset 12. Låsefremspringene kan indføres i låseåbningerne 40, når man ønsker at holde spændeskeden i beskyttende, sammentrykket stilling i forhold til huset 12 ved transport eller opbevaring af redskabet i en værktøjskasse, idet spændeskeden i modsat fald af tilbageføringsfjederen 38 føres i sin aksialt udstrakte stilling som vist.A bucket sheath 28 is also supported by the housing 12 and 30 has a pair of holding guide members 30, 32 extending forwardly axially displaceable in retaining channels shown in later figures, in the housing 12. The rear end portion 34 of the clamping sheath is substantially closed and is designed to contain an anvil surface 36, 35 touching a tension bar. A tension sheath return spring 38 is held axially compressible in the tension between the end portion 34 and the upper end 16 of the housing 12. Each of the holding guide members 30, 32 is provided with a locking opening 40 cooperating with a locking projection shown. in later figures, and carried on the inner surface of each of a pair of flexible locking tabs 44 carried by the rear end of the housing 12. The locking projections can be inserted into the locking openings 40 when it is desired to hold the clamping sheath in protective compression. position relative to the housing 12 when transporting or storing the implement in a tool box, otherwise the clamping sheath of the return spring 38 is guided in its axially extended position as shown.

I fig. 2 er yderligere detaljer af redskabet 10's vigtigste elementer vist i en delvis gennemskåret 15 udgave af den tidligere figur. F.eks. er hele den gennemsigtige cylinder 20's længde blotlagt, og det bemærkes, at cylinderen er en enkel, hul og tyndvægget, ret cirkulær cylinder, der er åben i begge ender, idet den eneste uregelmæssighed er et par låseskuldre 20 46, der glider langs ikke viste styrekanaler, der er dannet i den indre overflade af huset 12, og som bevirker et låseindgreb af bajonettypen med en tilsvarende i senere figurer vist udformning af huset 12 anbragt ved dettes bageste ende 16.In FIG. 2, further details of the main elements of the implement 10 are shown in a partially cut-away 15 version of the previous figure. Eg. the entire length of the transparent cylinder 20 is exposed and it is noted that the cylinder is a simple, hollow and thin-walled, rather circular cylinder open at both ends, the only irregularity being a pair of locking shoulders 20 46 sliding along not shown. control channels formed in the inner surface of the housing 12, which cause a bayonet-type locking engagement with a corresponding embodiment of the housing 12 shown at its rear end 16 shown in later figures.

25 På fig. 2 er den forreste ende af det ene af holdestyredelene 32 ligeledes blotlagt. Spændeskeden 28 holdes i huset 12 ved hjælp af holdefremspring 48, der er støbt ud i et med den forreste ende af hvert af holde-styredelene. Holdefrem-30 springene glider aksialt langs hver sin samvirkende rille i huset 12’s indre overflade og fastholdes imod udstødning bagud ved hjælp af en stoppekant 50 på huset 12. Den bøjelige låsefane 44's låsefremspringsdel 52 er ligeledes vist.25 In FIG. 2, the front end of one of the holding guide members 32 is also exposed. The clamping sheath 28 is held in the housing 12 by means of retaining projections 48 which are cast into one with the front end of each of the retaining guide parts. The holding protrusions slide axially along each cooperating groove in the inner surface of the housing 12 and are held against rearward ejection by a stop edge 50 on the housing 12. The locking protrusion portion 52 of the flexible locking tab 44 is also shown.

35 Stempelorganet 54 er vist og indeholder et stempel 56 og en stempel-O-ring 58, der er anbragt 141546 5 som sugepumpe i forhold til cylinderen 20. En spidsrensestang 60 bæres af stempelorganet og strækker sig fremad fra dette ind i mundstykket 22, når stemplet presses ind i sin spændte stilling. En 5 forholdsvis stiv sugeslags- eller rekylfjeder 62 er koblet aksialt spændt mellem stemplet 56 og den bageste del 16 af huset 12.The piston member 54 is shown and contains a piston 56 and a piston O-ring 58 disposed as a suction pump relative to the cylinder 20. A tip cleaning rod 60 is carried by the piston member and extends forwardly therefrom into the mouthpiece 22 when the plunger is pressed into its tense position. A relatively rigid suction stroke or recoil spring 62 is coupled axially tensioned between the piston 56 and the rear portion 16 of the housing 12.

I fig. 3 er vist slidser 64, 66 i huset 12 til fastholdelse af tungeelementerne 30, 32's fremspring.In FIG. 3, slots 64, 66 are shown in the housing 12 for retaining the protuberances of the tongue members 30, 32.

10 Slidserne er støbt i huset 12's indre overflade og kan strække sig i hovedsagen i hele dennes længde.The slots are molded in the inner surface of the housing 12 and can extend substantially throughout its length.

På tegningen ses også husets skedelignende form i forw hold til cylinderen 20. Det ringformede mellemrum 67 mellem de to cylindriske elementer tjener to nyttige 15 funktioner, idet mellemrummet for det første danner en styringsvej for spændeskeden 28's aksialt forskydelige holde-styredele 30, 32, og for det andet tjener som skærm for luftudgangen fra stempelOrganet 54's sugepumpeslag. Udstødningsluft fra cylinderen 20 20 lukkes ud i det ringformede mellemrum 67 igennem en udstødningsåbning 68 i nærheden af cylinderen 20's bagende. Derfra presses luften brat fremad langs cylinderens ydre overflade og endelig ud i atmosfæren, der omgiver instrumentets spids. Skær-25 men søger at bringe små stykke af loddemateriale eller dråber af smørelse eller andre fremmedlegemer til aflejring i det ringformede mellemrum 67.The drawing also shows the casing-like shape of the housing in relation to cylinder 20. The annular gap 67 between the two cylindrical elements serves two useful functions, the gap first forming a guide path for the axially displaceable holding members 30, 32 of the clamping sheath 28, and secondly, serves as a shield for the air output from the suction pump stroke of piston member 54. Exhaust air from cylinder 20 20 is vented into annular space 67 through an exhaust opening 68 near the rear of cylinder 20. From there, the air is squeezed abruptly along the outer surface of the cylinder and finally into the atmosphere surrounding the tip of the instrument. Cut-25 but seeks to bring small pieces of solder or drops of grease or other foreign matter to deposit in the annular space 67.

Således beskyttes følsomme elektroniske kredsløb og lignende imod forurening eller anden lignende 30 beskadigelse. Som det fremgår af senere figurer, kan overfladerne, der begrænser det ringformede mellemrum, let renses for de opsamlede fremmedlegemer.Thus, sensitive electronic circuits and the like are protected against pollution or other similar damage. As can be seen in later figures, the surfaces which limit the annular space can be easily cleaned of the foreign matter collected.

Ser man på stempelorganet 54, ses det, at rensestangen 60 er en fremadrettet forlængelse af 35 stempelstangen 70, på hvilken stemplet 56 er monteret, og som har en spændestang 72, der Strækker 6 141546 sig bagud, og hvis ende 74 berøres af spændeskeden 28's amboltoverflade 36 under stemplets manuelle spændingsslag. Et blødt gummistøddæmperelement 75 kan være indlagt eller på anden måde fastgjort til den 5 ydre overflade af den bageste del 34 af spændeskeden til forbedret fastgriben, når redskabet spændes ved at lægge enden 34 imod arbejdsbordet og trykke spændeskeden ind i huset 12.Looking at the piston member 54, it is seen that the cleaning rod 60 is a forward extension of the piston rod 70, on which the piston 56 is mounted, and which has a clamping rod 72 which extends rearwardly and whose end 74 is touched by the clamping sheath 28 anvil surface 36 below the manual tension stroke of the piston. A soft rubber shock absorber element 75 may be inserted or otherwise attached to the outer surface of the rear portion 34 of the clamping spoon for improved grip when the implement is clamped by inserting the end 34 against the work table and pressing the clamping spoon into the housing 12.

Spænde- eller sugeslagsfjederen 62 er ud-10 spændt over stempelstangen 70 i spænding mellem sin krogende 76, der.er fastgjort til huset 12's bageste endedel, og sin forreste krogende 78, der er fastgjort til stemplet 56's bagside. Når stempelorganet skydes fremad i sit spændeslag imod spændefjederen 15 62's spænding, griber aftrækkerlåsedelen 88 ind i spændestangen 72's aftrækkerlåsedel 80 og holder stempelorganet i dets forreste stilling som vist i fig. 4, indtil aftrækkeren 82 trykkes ind for at udløse det og tillader det at løbe tilbage til dets 20 bageste, uspændte stilling bag i huset 12.The clamping or suction spring 62 is tensioned over the piston rod 70 in tension between its hook 76 which is attached to the rear end portion of the housing 12 and its front hook 78 attached to the back of the piston 56. As the piston member is pushed forward in its clamping stroke against the tension of the clamping spring 15 62, the trigger lock member 88 engages the trigger lock portion 80 of the clamping rod 72 and holds the piston member in its forward position as shown in FIG. 4 until the trigger 82 is depressed to release it and allows it to retract back to its rear 20 unstressed position in the rear of the housing 12.

Af fig. 4 ses det også, at spidsrensestang-fremspringet 60 i den spændte stilling automatisk indføres i mundstykket 22's boring 83 og således renser det for fremmed materiale, der er aflejret der 25 under tidligere sugeslag.In FIG. 4, it is also seen that the tip cleaning rod projection 60 in the tensioned position is automatically inserted into the bore 83 of the nozzle 22 and thus cleans it of foreign material deposited there 25 during previous suction blows.

I fig. 5 er adskillelsen af cylinderen 20 og huset 12 vist. Låseskuldrene 46 af bajonettypen glider aksialt i styreslidser 84, der som vist er fremstillet i huset 12's indre overflade. Under samling, 30 f.eks. efter rensning og smøring af cylinderen 20, sættes en inskription "tryk ind" på cylinderen 20 på linie med en inskription "ind" på huset 12's løb, hvilket lægger låseskuldrene 46 på linie med styreslidserne 84. Fuld indføring foretages derefter, 35 og cylinderen drejes nogle få grader i urets retning for at låse enheden ved bajonetindgreb med den bugtede del ved den bageste ende af slidsen 84. Styre 141546 7 slidserne 64, 66 for spændeskeden 28's holde-styredele 30, 32 er også vist i fig. 5 og må skelnes fra cylinderstyreslidserne 84.In FIG. 5, the separation of cylinder 20 and housing 12 is shown. The bayonet-type locking shoulders 46 slide axially into guide slots 84, as shown in the inner surface of the housing 12. During assembly, e.g. after cleaning and lubricating the cylinder 20, an inscription "push in" on the cylinder 20 is aligned with an inscription "in" on the housing of the housing 12, which aligns the locking shoulders 46 with the guide slots 84. Full insertion is then made, 35 and the cylinder is rotated. a few degrees in the clockwise direction to lock the unit in bayonet engagement with the curved portion at the rear end of slot 84. Guide slots 64, 66 for clamping spacer 28 holding guide members 30, 32 are also shown in FIG. 5 and must be distinguished from the cylinder guide slots 84.

Udstødningsporten 68 i siden af cylinderen 20 5 er i den viste udførelsesform anbragt på linie med en af slidserne 84, hvorved udstødningsluften fra sugeslaget yderligere begrænses til at løbe langs denne og kan kontrolleres, når den forlader redskabets umiddelbare omgivelser. Det skal bemærkes, at ud-10 stødningsporten med vilje ikke er anbragt ved cylinderen 20's helt bageste ende. Som det klarere fremgår af fig. 3, ligger porten foran stempelringen 58 i den ikke spændte stilling, hvorved en luftpude under stemplets tilbageløbsslag indespærres ^5 bag stemplet for gradvis at nedsætte dets hastighed og derved formindske stødimpulsen, når fjederen i modsat fald ville slå imod sine egne vindinger og bagenden af huset 12. Denne pudevipkning formindsker rekylvirkningen og følgelig mundstykket 22's for-2o skydning bort fra det ønskede anvendelsespunkt på arbejdsstykket.The exhaust port 68 in the side of the cylinder 20 5 is in the illustrated embodiment aligned with one of the slots 84, whereby the exhaust air from the suction stroke is further limited to run along it and can be controlled as it exits the immediate surroundings of the implement. It should be noted that the ejection port is not intentionally disposed at the far rear end of the cylinder 20. As can be seen more clearly in FIG. 3, the gate in front of the piston ring 58 is in the unstressed position whereby an air cushion during the return stroke of the piston is trapped 5 behind the piston to gradually decrease its speed, thereby reducing the shock pulse when the spring would otherwise strike its own turns and the rear of the housing. 12. This cushion tilt reduces the recoil effect and, consequently, the forward orifice 22 of the nozzle 22 away from the desired point of use of the workpiece.

Aftrækkermekanismen 18, der er vist i fig.The trigger mechanism 18 shown in FIG.

6, omfatter et hus, der er dannet ud i ét med den bageste del 16 af huset 12. En aftrækkerlåsedel 25 88 holdes i boringen 89 i huset ved hjælp af stempel stangen 70-72, der går igennem en åbning 90 i den.6, comprises a housing formed integrally with the rear portion 16 of the housing 12. A trigger lock portion 25 88 is held in the bore 89 of the housing by means of the piston rod 70-72 passing through an opening 90 therein.

Åbningen 90 har en holderand 92, der griber ind i aftrækkerlåsedelen 80 på stangen 70-72, når denne er skubbet fremad under spændeslaget. Randen 92's 30 kant kan være forstærket ved hjælp af en metalskive 94, der som vist er anbragt på åbningen 90's nedre overflade. Aftrækkerlåsedelen 88's holderand 92 holdes i indgreb med ansatsen 80 ved hjælp af en trykfjeder 96, der er anbragt mellem bunden af 35 boringen og bunden af aftrækkerlåsedelen 88. Når aftrækkerlåsedelen 88 trykkes ned, trykkes fjederen 96 yderligere sammen, og holderanden 92's kant for- 8 141546 skydes bort fra sin holdende berøring med låsedelen 80. Dette tillader stempelorganet at bevæge sig tilbage.The aperture 90 has a retainer edge 92 which engages the trigger lock portion 80 of the rod 70-72 as it is pushed forward under the tension stroke. The edge of the rim 92 may be reinforced by a metal disk 94, as shown on the lower surface of the opening 90. The retainer 92 of the trigger lock portion 88 is held in engagement with the shoulder 80 by a compression spring 96 disposed between the bottom of the bore and the bottom of the trigger lock portion 88. As the trigger lock portion 88 is depressed, the spring 96 is further compressed and the edge of the retainer 92 is pressed 8. 141546 is pushed away from its holding contact with the locking member 80. This allows the piston member to move back.

Når man ønsker at forskyde stempelstangen 5 70-72 yderligere fremad til grundig rensning af spidsen 22's boring 83 eller til udstødelse af spidselementet 24 ved at støde til det med stemplet 56 altsammen som vist i fig. 8, tillader aftrækkerholderanden 92's palvirkning yderligere 10 fremadgående bevægelse af stangen uden at tillade utilsigtet tilbageløb af stempelorganet, eftersom låsedelen 80, når den udløses, atter vil holdes af randen 92, indtil aftrækkerlåsedelen 88 forsætligt trykkes ind. I fig, 7 er de bøjelige låsefa-15 ner 44 på huset 12 vist med deres låsefremsprings-dele 52 i indgreb med holde-styredelens ikke viste låseåbninger 40. Låsefremspringsdelene 52 holdes i åbningerne 40 ved spændeskedetilbageføringsfjederen 38's sammentrykning. Når man ønsker at udløse spæn-20 deskeden fra lager- eller transportstilling, behøver man blot at trykke spændeskeden lidt fremad, dette tillader de eftergivende faner 44 at springe udad og automatisk bringe låsefremspringene ud af indgreb med åbningen 40. Derpå føres spændeskeden 28 .25 tilbage af fjederen 38 til sin fuldt udstrakte stilling som vist i fig. 8.When it is desired to move the piston rod 5 70-72 further forward to thoroughly clean the bore 83 of the tip 22 or to eject the tip member 24 by abutting it with the piston 56 as shown in FIG. 8, the paw action of the trigger retainer 92 permits further forward movement of the rod without allowing unintentional retraction of the piston member since, when released, the locking member 80 will again be held by the rim 92 until the trigger locking member 88 is intentionally pressed. In Fig. 7, the flexible locking tabs 44 on the housing 12 are shown with their locking projection portions 52 in engagement with the locking openings of the holding guide portion 40. The locking projection portions 52 are held in the openings 40 by the compression of the sheath return spring 38. When you want to release the clamp from storage or transport position, you just have to push the clamp spoon slightly forward, this allows the resilient tabs 44 to jump outwards and automatically bring the locking projections out of engagement with the opening 40. Then the clamp spoon 28 is inserted. back of the spring 38 to its fully extended position as shown in FIG. 8th

Særligt bemærkelsesværdige er fordelene ved det ringe rekyl som følge af stempelenhedens ringe masse og 30 sikkerheden for operatøren som følge af, at spændestemplet er skærmet under tilbageløbsslaget. Sammenpakningslåsningen af spændeskeden skal også specielt bemærkes på grund af den beskyttelse den giver redskabet, og den mere kompakte udformning af redskabet ved opbe-35 varing.Particularly noteworthy are the advantages of the low recoil due to the low mass of the piston unit and the safety of the operator due to the fact that the piston is shielded during the return stroke. The packing locking of the clamping spoon must also be particularly noted because of the protection it provides for the implement and the more compact design of the implement when stored.
