Description

Rotatable spanner

Technical field

The utility model belongs to wrench group.

Background technology

Conventionally Wrench head has fixed or ratchet cassette, or the syllogic control operation of turning left right-hands rotation, stopping, but the level of driving head is applied industry use to reversing; Therefore have vertically to rotation ratchet head, with more convenient operator, general vertical deflection from an angle to rotation ratchet head that can only make, and 360 deg rotates comprehensively, for dead angle place and operability, operator cannot move flexibly; In addition, the handle of conventional spanner, often divides into the specification of short handle, middle handle and nigger, need to have the length of number of sizes to make, and except industry increases cost, user also needs to increase collection space, to use the spanner of different length, and more inconvenient.

Utility model content

Can not rotate and the inconvenient deficiency of adjusting spanner length by 360 degree in order to overcome existing driving end, the utility model provides a kind of rotatable spanner, and this rotatable spanner has not only improved the flexibility ratio using, and is convenient to storage, has increased the scope of application.

The utility model solves the technical scheme that its technical problem adopts: a kind of rotatable spanner, comprise, and leader's one handle, a front articulated section and a ratchet head, described handle front end is described handle, and described handle front end is front articulated section, and its structure is:

Closely, by described handle place, there is a vacancy described front articulated section, and described vacancy central authorities have one to crack, described in crack and extend to described handle and have a segment distance;

Described front articulated section is semicircular forked type, and being provided with hole in its front both sides can be for the projection pivot joint of described ratchet head, and there is a screw described front articulated section, is screwed into for a screw rod.

There is a driving head in the front of described ratchet head, and there is a driving head less than described driving head at the back side, and larger described driving head can be by described vacancy.

Above-mentioned rotatable spanner, its structure is: described handle is provided with a perforation radially running through, described gim peg can be through the cracking of described handle, described handle and described handle capable of regulating length be fixed together.

The beneficial effects of the utility model are because rotatable spanner has a front articulated section with pivot joint ratchet head, offer one cracks to shank precalculated position from front articulated section, described front articulated section wears a screw rod and cracks described in crossing, ratchet head just, reverse side is respectively provided with driving head, there is a vacancy at nearly shank place, described front articulated section, described driving head can pass through vacancy, described ratchet head can be done the rotation of longitudinal 360 deg, and just, the driving head of reverse side can be made horizontal 360 degree and reverse object to be driven, and the sheathed flexible handle of described handle, be used as retractable handle, to reach the object of person's flexible operating easy to use.

Detailed description of the invention

Detailed description of the invention of the present utility model is, as shown in the figure:

Embodiment 1, a kind of rotatable spanner, comprises, leader's 20 one handles 11, a front articulated section 12 and a ratchet head 13, described handle 20 front ends are described handle 11, and described handle 11 front ends are front articulated section 12, and its structure is:

Described front articulated section 12 is near has a vacancy 122 by described handle 11 places, and described vacancy 122 central authorities have one to crack 112, described in crack and 112 extend to described handle 11 and have a segment distance;

Described front articulated section 12 is semicircular forked types, and being provided with hole 121 in its front both sides can be for projection 131 pivot joint of described ratchet head 13, and there is a screw 123 described front articulated section 12, is screwed into for a screw rod 124.

There is a driving head 14 in the front of described ratchet head 13, and there is a driving head 15 less than described driving head 14 at the back side, and larger described driving head 14 can be by described vacancy 122.

According to above-mentioned textural association, as shown in Figure 2, when the utility model combination, first described front articulated section 12 is slightly outwards strutted, 112 summaries that make to crack become large, to make ratchet head 13 enter front articulated section 12, then the projection 131 of ratchet head 13 enters in the hole 121 of front articulated section 12 with pivot joint, screw in the hole 121 of front articulated section 12 with screw rod 124 again, the certain spacing of 112 maintenances makes to crack, described ratchet head 13 pivot joints are complete does not drop, also can bear certain twisting resistance, then handle 20 brute forces are engaged on handle 11, to complete assembling.

The described driving head 14,15 of described ratchet head 13 of the present utility model can be done forward and inverse turning, the even horizontal torsion of 360 degree, and described ratchet head 13 itself is complied with described projection 131 pivot joints, described larger driving head 14 can be by described vacancy 122, and make a predetermined angular or make longitudinal 360 degree rotation ratchet heads 13, just can utilize the described driving head 14,15 of double end, making various angles with convenient user reveals alive operation, even at dead angle place or confined space operation, also can play a role.

Above-mentioned rotatable spanner, described handle 20 is provided with a perforation radially running through 21, described gim peg 22 can through described handle 11 crack 112, described handle 20 and described handle 11 capable of regulating length be fixed together, described handle 20 can be harder plastic cement material and makes, or be clad metal pipe in plastic cement material, or entirely for metal material is made.
