In the concaveconvex structure at described sleeve two ends, wherein the concaveconvex structure of an end comprises corresponding two projections and two grooves that are provided with, and the inwall of two projections is an angular structure; The concaveconvex structure of the other end comprises corresponding two grooves or two grooves that are provided with, and the inwall of two grooves is an angular structure.

The relative both sides of described through-hole wall are respectively equipped with axial raised line, and the relative both sides of described each sleeve outer wall are respectively equipped with the axial notch adaptive with above-mentioned raised line.

The lower port of described T-handle is provided with external screw thread and is provided with axial slits, described screw to be covered with internal thread and can when screwing in the handle end opening, the handle end opening to be tightened up diminish.

Described location-plate comprises connecting plate and the positioning cap that fuses, and the end of connecting plate links to each other by a pivot pin and handle are rotatable, positioning cap be provided with sleeve on the suitable groove of projection, the inwall of groove is an angular structure.

Described T-handle is provided with the peep hole that is used to observe sleeve.

The utility model T-socket spanner since adopt above technical scheme, make it compared with prior art, have following advantage and characteristics:

1, utilizes interconnecting of sleeve itself, replaced sleeve extension rod;

2, each sleeve all is contained in the handle, forms an integral body, need not other accessory, and compact conformation is easy to use and carry;

3, possessed the punching function that conventional sleeve does not possess.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is depicted as a preferred embodiment of the present utility model, and the utility model is not limited to present embodiment.

Referring to Fig. 1, Fig. 2, Fig. 3, the T-socket spanner of present embodiment comprises T-handle 1, a plurality of sleeve 2, screws and cover 3 and location-plate 4.

Cooperation is referring to Fig. 4, Fig. 5, Fig. 6, be provided with the through hole 11 of up/down perforation in the straight-bar of the T-handle 1 in the utility model, the relative both sides of through hole 11 inwalls are respectively equipped with axial raised line 12, the lower port of T-handle is provided with external screw thread 13 and is provided with axial slits 14, and the straight-bar of T-handle is provided with the peep hole 15 that is used to observe sleeve.

Cooperation is referring to Fig. 7, Fig. 8, Fig. 9, Figure 10, a plurality of sleeves 2 mutually nested integral body that are connected to form in the utility model are arranged in the through hole 11 of handle, a plurality of sleeves 2 have the identical external diameter and the endoporus of different size, and the two ends of each sleeve are respectively equipped with and are used for mutually nested continuous concaveconvex structure.Wherein the concaveconvex structure of an end comprises that corresponding two projections 21 that are provided with and the inwall 211 of 22, two projections of two grooves are angular structure; The concaveconvex structure of the other end comprises that corresponding two grooves 23 that are provided with or the inwall 231 of 24, two grooves of two grooves are angular structure.The relative both sides of each sleeve 2 outer wall are respectively equipped with the axial notch 25 adaptive with the axial raised line 12 of handle through-hole wall.

Cooperation is referring to Fig. 3, and screwing in the utility model covered 4 lower ends that are connected T-handle, and this screws to be covered with internal thread 31 and can when screwing in the handle end opening handle end opening to be tightened up and diminishes.Screwing lid is positioned at a plurality of sleeves in the through hole 11 of handle from the lower end.

Cooperation is referring to Figure 11, location-plate 4 in the utility model comprises connecting plate 41 and the positioning cap 42 that fuses, the end of connecting plate is by 1 rotatable linking to each other an of pivot pin 5 and handle, positioning cap 42 be provided with sleeve 2 on the suitable groove 43 of projection 21, the inwall 431 of groove is an angular structure.Location-plate 4 is positioned at a plurality of sleeves in the through hole 11 of handle from the upper end.

Each sleeve in the utility model all can take out above or below handle.A plurality of sleeves permutation and combination arbitrarily are integral in the through hole that is arranged on handle, when needs use the sleeve of which specification, this sleeve need only be arranged on bottom and get final product.After sleeve installs, will screw lid and tighten, the end opening of handle promptly draws in and diminishes, and can not drop from the below thereby sleeve is positioned in the through hole of handle.After covering location-plate, location-plate is positioned at sleeve in the through hole of handle from the top again.Axial notch 25 on each sleeve links to each other with the axial raised line of handle through-hole wall 12 mutual cutting ferrules, makes sleeve can not take place radially to rotate.At this moment turning handle can drive the sleeve unitary rotation, thereby plays the effect of spanner.
