Abstract
The utility model discloses a screw. The screw comprises a screw head and a threaded rod, wherein a groove is formed in the screw head; a wire winding device is arranged in the groove; a strip-shaped groove is formed between the head and the tail of the threaded rod and is communicated with the groove; a thin steel wire penetrates in the strip-shaped groove; one end of the thin steel wire is fixedly connected with the tail of the threaded rod; and the other end of the thin steel wire is wound on the wire winding device. The screw can be conveniently detached when broken, and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of fastening piece, is specifically related to a kind of screw.
Background technique
Screw is very common a kind of fastening piece in life.Screw in use, screw is driven in wall with tup, on wall, will form the mounting hole of mounting screw, screw is fixed on wall, sometimes improper what use, tup is too exerted oneself, screw can rupture, after screw extraction, general dismounting can only be by one end dismounting place being connected with screw head, and the other end rupturing will be embedded in mounting hole, cannot conveniently take apart, screw in mounting hole takes apart not in time, just cannot continue new work, affects working efficiency.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of screw, and while there is broken nail, for convenience detach, working efficiency is higher.
For achieving the above object, the utility model provides following technological scheme: a kind of screw, comprise screw head and screw rod, described screw head is provided with groove, in described groove, be provided with coiling apparatus, between the head and the tail of described screw rod, be provided with bar-shaped trough and described bar-shaped trough and groove and be connected, in described bar-shaped trough, be equipped with finer wire, one end of described finer wire is fixedly connected with the afterbody of screw rod, the other end of described finer wire be set around on coiling apparatus.
By adopting technique scheme, screw is driven in after wall, if there is the situation of broken nail in screw, now this section of screw head is taken out in mounting hole, head at screw is provided with groove, in groove, be provided with coiling apparatus, on screw rod, establish bar-shaped trough, in bar-shaped trough, be equipped with finer wire, one end of finer wire is fixedly connected with the afterbody of screw rod, the other end winding of finer wire is on Winder, when taking out after the head of broken nail, finer wire on coiling apparatus can constantly elongate along with the motion of screw head, screw head is taken out completely in mounting hole, between the screw breaking, just connected by finer wire, can other one section of screw breaking in mounting hole be pulled out along finer wire, such setting, can fast the broken nail in wall mounting hole be pulled out, new screw is installed, increase work efficiency, time saving and energy saving.
The utility model is further set to: described coiling apparatus comprises distaff, and the two ends of described distaff are embedded at screw head and described distaff and can rotate in a circumferential direction.
By adopting technique scheme, after screw extraction, by after one section of taking-up of screw head, the finer wire of winding on distaff can constantly extend along with rotating in a circumferential direction of distaff, well avoid the screw situation that fracture causes finer wire also and then to rupture suddenly, the length of finer wire can extend, and facilitates the dismounting of broken nail, ensures the working efficiency causing.
The utility model is further set to: the cross section of described bar-shaped trough is less than 1/8th of screw rod cross section
By adopting technique scheme, the cross section size of bar-shaped trough is arranged to be less than 1/8th of screw rod cross section, when can ensureing to wear finer wire in screw rod, can not reduce again the intensity of screw rod itself, when use, reliability is higher.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model screw.
In figure: 1, screw head; 2, screw rod; 3, groove; 4, coiling apparatus; 5, bar-shaped trough; 6, distaff; 7, finer wire.
Embodiment
Shown in Fig. 1, a kind of screw of the present embodiment, comprise screw head 1 and screw rod 2, described screw head 1 is provided with groove 3, in described groove 3, be provided with coiling apparatus 4, between the head and the tail of described screw rod 2, be provided with bar-shaped trough 5 and described bar-shaped trough 5 and groove 3 and be connected, in described bar-shaped trough 5, be equipped with finer wire 7, one end of described finer wire 7 is fixedly connected with the afterbody of screw rod 2, the other end of described finer wire 7 be set around on coiling apparatus 4.
By adopting technique scheme, screw is driven in after wall, if there is the situation of broken nail in screw, now this section of screw head 1 is taken out in mounting hole, head 1 at screw is provided with groove 3, in groove 3, be provided with coiling apparatus 4, on screw rod 2, establish bar-shaped trough 5, in bar-shaped trough 5, be equipped with finer wire 7, one end of finer wire 7 is fixedly connected with the afterbody of screw rod 2, the other end winding of finer wire 7 is on Winder, when taking out after the head 1 of broken nail, finer wire 7 on coiling apparatus 4 can be along with the motion of screw head 1 is constantly elongated, screw head 1 is taken out completely in mounting hole, between the screw breaking, just connected by finer wire 7, can other one section of screw breaking in mounting hole be pulled out along finer wire 7, such setting, can fast the broken nail in wall mounting hole be pulled out, new screw is installed, increase work efficiency, time saving and energy saving.
Described coiling apparatus 4 comprises distaff 6, and the two ends of described distaff 6 are embedded at screw head 1 and described distaff 6 and can rotate in a circumferential direction.
By adopting technique scheme, after screw extraction, by after one section of taking-up of screw head 1, the finer wire 7 of winding on distaff 6 can constantly extend along with rotating in a circumferential direction of distaff 6, well avoid the screw situation that fracture causes finer wire 7 also and then to rupture suddenly, the length of finer wire 7 can extend, and facilitates the dismounting of broken nail, ensures the working efficiency causing.
The cross section of described bar-shaped trough 5 is less than 1/8th of screw rod 2 cross sections
By adopting technique scheme, the cross section size of bar-shaped trough 5 is arranged to be less than 1/8th of screw rod 2 cross sections, when can ensureing that screw rod 2 is interior and can wear finer wire 7, can not reduce again the intensity of screw rod 2 itself, when use, reliability is higher.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technological schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
