Abstract
The utility model relates to a hand tool for fixing cement steel nails when an electrician lays sheathed wires along a wall surface or a ceiling, which is mainly composed of an inner case, an outer case, springs, hammers, a subbase, and a steel nail block and uses compression spring energy storage of the inner case in the outer case, and the hammers obtain kinetic energy and stroke cement steel nails to be fixed on the wall surface after releasing. Owing to the nylon clamp of the cement steel nail isn't used to be depressed by hand in use, and hence, avoids the danger of the accidental injury by hammer; in the meantime, owing to small volume, light weight, and easy operation, and thus, reduces labor strength of the executive and enhances work efficiency.
Description
The utility model is a kind of electrician is used for fixing 6 millimeters or 8 millimeters cement steel nails when laying protective case wire a hand-operated tools.
The electrician uses the cement steel nail that protective case wire is fixed on metope or the ceiling at the indoor protective case wire that lays along metope or along ceiling often.Existing mode of operation is that the operator blocks protective case wire with the nylon clamp of cement steel nail and on the other hand by on metope, another hand-held hammer impacts steel nail in the body of wall, this mode of operation needs bimanualness, need ascend a height during laying wires on ceiling especially and face upward an operation, and labour intensity is big.Because the nylon clamp volume of cement steel nail is less, pin its careless slightly will the accidental injury of finger by hammer.
Task of the present utility model provides a kind of hand-operated tools that is used for fixing the cement steel nail of 6 millimeters or 8 millimeters, and it can be fixed on the cement steel nail on metope or the ceiling easily.The nylon clamp of cement steel nail because it needn't press...with one's finger in use, the danger of therefore having avoided finger to be accidentally injured by hammer.Because its volume is little, in light weight, the simple and one-hand operation of operational motion has alleviated the labour intensity of construction, has improved operating efficiency simultaneously.
The utility model is to utilize spring energy-storage, makes tup obtain kinetic energy after the release, impacts the cement steel nail with tup again, the inner casing ［ 8 ］ that has an energy to slide in shell ［ 13 ］ according to this reason cement steel nail fixator.For inner casing can being slided in shell and can not breaking away from, on shell, fix a return pin ［ 14 ］, the gathering sill that the other end of pin is passed on the inner casing stretches in the inner casing.Return pin plays two effects, and the one, make tup get back to cocked orientation, the 2nd, place restrictions on the move distance between inner casing and the shell, they can not broken away from.Tup ［ 4 ］ is used for impacting steel nail, and it can slide in inner casing.When tup was in cocked orientation, ［ 7 ］ fond of gossip were stretched into inner casing and are blocked tup.(can reduce axial length like this) other end is against on the bonnet ［ 1 ］ that connects with shell in ［ 2 ］ insertions of kinetic energy spring tup hole.A base ［ 15 ］ is installed in the bottom of inner casing, and the effect of base is to support steel nail box ［ 9 ］.A groove is arranged at the bottom of base, when in the steel nail box insertion groove, the steel nail axis that is positioned at first piece of cement steel nail ［ 16 ］ of steel nail box just be in the same axis of tup on.Can be not crooked when guide shaft ［ 11 ］ can make the kinetic energy spring be compressed.Opening a groove on the shell is that the cover fond of gossip ［ 6 ］ that is fixed on when shell moves on the inner casing stops.
Earlier the cement steel nail is packed into during operation cement steel nail fixator in the steel nail box, again the steel nail box is inserted in the groove of base bottom, nylon clamp ［ 17 ］ with first piece of cement steel nail in the steel nail box blocks protective case wire and base is against on the metope then, postpone lid and make the shell motion, the kinetic energy spring is compressed simultaneously, make tup obtain kinetic energy, when the collision block on being fixed on shell ［ 3 ］ promoted the lateral pin ［ 5 ］ on fond of gossip and makes fond of gossip retreating, tup impacted steel nail towards the motion of base direction under the effect of kinetic energy spring.When for the first time impacting to be pinned to steel nail the time, can repeat to impact, but base will be propped up metope all the time will note operating the time.Base leaves the first piece of cement steel nail that is positioned at the steel nail box behind the metope and breaks away from the steel nail box on the metope owing to being fixed on during EO, and the second piece of cement steel nail that at this moment is positioned at the steel nail box is pulled to the steel nail box under the effect of sending langrage spring ［ 10 ］ forefront is in to be waited to impact on the seat.Inner casing stretches out shell under the effect of back-moving spring ［ 12 ］ simultaneously, and the return pin drive tup that is fixed on the shell is got back to cocked orientation.
The inside and outside shell of cement steel nail fixator can be made with seamless steel pipe.Tup is because impact steel nail, so tup head hardness should be more than HRC60.Bonnet and base are injection molded into engineering plastics.The sheet metal punching out of steel nail box.
Claims (3)
1, a kind of hand-operated tools that is used for fixing the cement steel nail, mainly contain shell [13], inner casing [8], tup [4], collision block [3], [7] fond of gossip, cover fond of gossip [6], base [15], kinetic energy spring [2] and steel nail box compositions such as [9], the other end that it is characterized in that being fixed on the return pin [14] on the shell stretches into inner casing.
2, the instrument of saying according to claim 1, it is characterized in that being fixed on can promote when collision block ［ 3 ］ on the shell ［ 13 ］ moves with shell ［ 7 ］ fond of gossip flexible in cover fond of gossip ［ 6 ］, stretch into during fond of gossip stretching out in the inner casing ［ 8 ］, retreat to the inner casing outer wall during retraction.
3, the instrument of saying according to claim 1 is characterized in that the groove that can insert steel nail box ［ 9 ］ is arranged at the bottom of base ［ 15 ］.
