The utility model discloses a further improvement, be provided with the gasket between driven bevel gear and the support.

The utility model discloses a further improvement, drive bevel gear and driven bevel gear tooth ratio do not exceed 1: 3.

The utility model discloses a further improvement, the sleeve is omnipotent sleeve, and the sleeve tip is six claw chuck structures.

The utility model provides a novel box spanner has following characteristic:

1) when the tool is used, the handle is rotated to rotate around the axis of the tool, the driving bevel gear and the driven bevel gear are meshed and rotate with each other, the handle rotates around the connector to adjust the angle of the handle, when the handle is rotated to a proper angle, the handle is gripped to be fixed without autorotation, the driving bevel gear and the driven bevel gear are meshed but do not rotate relatively, the connector can be driven to rotate by pulling the handle at the moment, and the connector drives the sleeve to rotate to finish screwing or unscrewing actions of a workpiece;

2) the wrench is simple in integral structure, easy to implement, lower in cost and longer in service life compared with the existing wrench which can be adjusted randomly;

3) the spanner adopts omnipotent sleeve in this application, and application scope is wide and easily carry.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 and 2, the novel socket wrench comprises a handle 1 and a connector 5, wherein the handle 1 is of a cylindrical rod-shaped structure, a connecting cylinder 2 is movably sleeved on the handle 1, and the handle 1 rotates around the axis of the handle 1 in the connecting cylinder 2. Be provided with support 3 on connecting cylinder 2, support 3 has two crooked bar boards to constitute, 3 one end fixed connection of support in connecting cylinder 2, and the bar board of the 3 other ends of support is parallel to each other and corresponds and be provided with connecting hole 301, and connecting hole 301 is circular through-hole. The support 3 is provided with a connector 5, as shown in fig. 3, the connector 5 includes a mandrel 501, the mandrel 501 is a cylindrical shaft, one end of the mandrel 501 is provided with a connecting square head 503 for connecting a sleeve, the mandrel 501 is connected with a driven bevel gear 502 through a key, the end of the handle 1 is fixedly connected with a driving bevel gear 4 engaged with the driven bevel gear 502, and the gear ratio of the driving bevel gear 4 to the driven bevel gear 502 is 1: 3.
