Abstract

The utility model discloses a screwdriver, which comprises a handle and a toolbar, and also comprises a grip and a connecting strip. The grip is fixedly arranged at one end of the connecting strip; the other end of the connecting strip is fixedly arranged at one end of the handle, which approaches the toolbar; one connecting strip groove is arranged at the side end of the handle; and one grip groove is arranged at the tail end of the handle. When the screwdriver is not in use, the grip is placed in the grip groove; the connecting strip is placed in the connecting strip groove; and the length of the connecting strip is equivalent with that of the toolbar. The connecting strip and the grip are both made of elastic materials. The cross section of the connecting strip groove is C-shaped. One cylindrical boss is arranged corresponding to the central position of the grip in the grip groove, and when the grip is placed in the grip groove, the grip is gripped on the cylindrical boss. By using the screwdriver, a screw can be prevented from falling when the screw is assembled and disassembled.

Description

A kind of screwdriver

Technical field

The utility model belongs to the screwdriver design field, particularly a kind of screwdriver that can prevent the screw landing.

Background technology

Screwdriver is people's a kind of instruments commonly used in daily life, when using screwdriver, often need be used with screw.In the prior art, be mostly people directly with screw hand held in, left hand is with the place of screw fixings at need nails; The right hand is tightened with screwdriver; Need two hands to cooperate, the end of some screwdriver is magnetic, can hold screw; But screw tends to rotate, and still needs the people to adjust by hand.When especially the people carries out work high above the ground,, can be easy to cause danger, and the problem of screw landing takes place in the words of a hand easily if two hands all need operation.

Therefore, a kind of screwdriver that can when setscrew, prevent the screw landing need be provided.

The utility model content

The shortcoming that the main purpose of the utility model is to overcome prior art provides a kind of screwdriver with not enough, and this screwdriver is the while setscrew in use, prevents the screw landing.

The purpose of the utility model realizes through following technical scheme: a kind of screwdriver, comprise handle and knife bar, and also comprise folder mouth and connection strap; Said folder mouth is " C " type, and said folder mouth is fixed on an end of connection strap, and the connection strap other end is fixed on the end of handle near knife bar; The handle side has a connection strap groove, and the handle tail end has a folder port recess, when not using; The folder mouth is placed in the folder port recess, and connection strap is placed in the connection strap groove; The length of said connection strap is suitable with the length of knife bar.In use, screw is placed in the folder mouth.

Preferably, said connection strap is processed by elastomeric material with the folder mouth.For example rubber, plastics etc.Because the size of screw is varied; A folder mouthful employing elastomeric material can make this utility model ability screw that is applicable to different-diameter as much as possible; Thickness because of the screw head of a nail also has nothing in common with each other simultaneously, the distance that connection strap adopts elastomeric material can suitably regulate knife bar top and screw.

Further, said connection strap groove cross section becomes " C " type.After finishing using, can give the connection strap certain pressure, it is embedded in the connection strap groove, thereby can influence the use of screwdriver because connection strap crosses pine.

As preferred version, be provided with a cylinder convexity corresponding to the Jia Kou center in the said folder port recess, in the time of in Jia Kou is positioned over the folder port recess, the folder mouth is clipped on the cylinder convexity.Thereby make the folder mouth can not drop out folder port recess or mobile in the folder port recess.

The course of work of the utility model: when not using screwdriver; The folder mouth is fixed in the folder port recess of handle tail end, and connection strap is fixed in the connection strap groove, when using screwdriver; If screw will be installed; Then will press from both sides mouthful with connection strap and all in groove, pull out, folder mouthful is clamped the screw ailhead and is installed then, just can take off the folder mouth after screw is installed to a certain degree and continue an installation again; If will dismantle screw, then can, screw load onto the folder mouth when taking apart certain length, and clamp ailhead, thereby can make the unlikely landing of screw after the dismounting.

The utility model compared with prior art has following advantage and beneficial effect:

1, the utility model can prevent the screw landing through folder mouthful and connection strap are set when the installation and removal screw on screwdriver, and should folder mouth and connection strap all be positioned in the groove that is provided with on the handle, can not influence other normal uses.

2, folder mouth in the utility model and connection strap all adopt elastomeric material to process, and can adjust according to the model of screw, and range of application is wider.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but the embodiment of the utility model is not limited thereto.

Embodiment 1

As shown in Figure 1, a kind of screwdriver comprises handle 1, knife bar 2, folder mouth 3 and connection strap 4; Said folder mouth 3 is fixed on an end of connection strap 4, and connection strap 4 other ends are fixed on the end of handle 1 near knife bar 2, and handle 1 side has a connection strap groove 6; Handle 1 tail end has a folder port recess 5; When not using, folder mouth 3 is placed in the folder port recess 5, and connection strap 4 is placed in the connection strap groove 6; The length of the length of said connection strap 4 and knife bar 2 is suitable.In use, screw is placed in the folder mouth 3.

Connection strap 4 and folder mouthfuls 3 are processed by this elastomeric material of rubber in the present embodiment.A folder mouthful employing elastomeric material can make this utility model ability screw that is applicable to different-diameter as much as possible, simultaneously because the thickness of the screw head of a nail also has nothing in common with each other, and the distance that connection strap adopts elastomeric material can suitably regulate knife bar top and screw.

As shown in Figure 1, connection strap groove 6 cross sections become " C " type.After finishing using, can give the connection strap certain pressure, it is embedded in the connection strap groove, thereby can influence the use of screwdriver because connection strap crosses pine.

As shown in Figure 2, said folder mouthfuls 3 be " C " type, and it is protruding 7 to be provided with a cylinder corresponding to the Jia Kou center in the said folder port recess 5, and when folder mouthfuls 3 was positioned in the folder port recess 5, folder mouth 3 was clipped on the cylinder convexity 7.Thereby make the folder mouth can not drop out folder port recess or mobile in the folder port recess.

The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
