Description

A kind of extending formula box spanner
Technical field
The utility model relates to a kind of spanner, and specifically a kind of extending formula box spanner, belongs to machine tool technical field.
Background technology
Box spanner is made up of multiple multiple members such as collet head and handle and connecting rod with hexagon ring or 12 jiaos of holes, be specially adapted to dismounting and fastening space of living in is very narrow or cave in very bolt or the nut of depths.
In machine work, often need to use box spanner to dismantle with fastening bolt or nut.In producing and living, the structure of widely used box spanner is generally all fixed at present, thereby cannot dismantle with fastening the bolt in different depth position or nut by the length of regulating sleeve spanner connecting rod, the box spanner that often needs workmen to carry multiple different length specification just can complete dismounting and fastening bolt in different depth position or the task of nut, so not only increase use cost, and increase workmen's labour intensity, be unfavorable for increasing work efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, easy to use, thereby and can dismantle and fastening extending formula box spanner the bolt in different depth position or nut by the length of regulating connecting rod.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of extending formula box spanner, comprise handle, through hole, screw rod, adjusting nut, fixed block, connecting rod, spring, expansion link, chamfering, collet head, one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the middle part of handle is provided with through hole, in through hole, be provided with screw rod, screw rod is provided with adjusting nut, the top of screw rod is provided with fixed block, one end of screw rod enters in connecting rod and is fixedly connected with the top of expansion link through the through hole that is arranged on handle middle part, the other end is fixedly connected with fixed block, in connecting rod, be provided with spring and expansion link, the lower end of expansion link is provided with chamfering, expansion link is by being arranged on the chamfering of lower end and the top of collet head is connected.
The drift of described spring is greater than the length of described screw rod.
In described connecting rod, be provided with hollow structure, thereby reach the flexible object of box spanner connecting rod by the length that adjustable telescopic rod stretches out connecting rod.
Compared with prior art, the utlity model has following beneficial effect: simple in structure, easy to use, the length of regulating sleeve spanner connecting rod in a big way, thereby can dismantle and fastening bolt or nut in different depth position, effectively reduce the quantity of the required box spanner carrying of workmen, not only can reduce use cost, and can reduce workmen's labour intensity, be conducive to increase work efficiency.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, shown in Figure 11 and Figure 12, a kind of extending formula box spanner, comprise handle 1, through hole 2, screw rod 3, adjusting nut 4, fixed block 5, connecting rod 6, spring 7, expansion link 8, chamfering 9, collet head 10, vertical being fixedly connected with in middle part of one end of described connecting rod 6 and handle 1, the middle part of handle 1 is provided with through hole 2, in through hole 2, be provided with screw rod 3, screw rod 3 is provided with adjusting nut 4, the top of screw rod 3 is provided with fixed block 5, one end of screw rod 3 enters in connecting rod 6 and is fixedly connected with the top of expansion link 8 through the through hole 2 that is arranged on handle 1 middle part, the other end is fixedly connected with fixed block 5, in connecting rod 6, be provided with spring 7 and expansion link 8, the lower end of expansion link 8 is provided with chamfering 9, expansion link 8 is connected with the top of collet head 10 by the chamfering 9 that is arranged on lower end.
The drift of described spring 7 is greater than the length of described screw rod 3.
In described connecting rod 6, be provided with hollow structure, thereby reach the flexible object of box spanner connecting rod 6 by the length that adjustable telescopic rod 8 stretches out connecting rod 6.
As Fig. 1, shown in Fig. 2 and Fig. 3, in the time of needs dismountings and fastening bolt in more shallow position or nut, first turn adjusting nut 4 screws out screw rod 3 in connecting rod 6, because one end of screw rod 3 enters in connecting rod 6 and is fixedly connected with the top of expansion link 8 through the through hole 2 that is arranged on handle 1 middle part, the other end is fixedly connected with fixed block 5, therefore expansion link 8 just can stretch into along the inwall of connecting rod 6 being arranged on when spring 7 in connecting rod 6 compresses, then collet head 10 is aimed at and need to be disassembled with fastening bolt or nut and be inserted in collet head 10, last turning handle 1 can be dismantled with fastening the bolt in more shallow position or nut.
As Fig. 4, shown in Fig. 5 and Fig. 6, in the time of needs dismountings and fastening bolt in putting compared with deep-seated or nut, first turn adjusting nut 4 screws in screw rod 3 in connecting rod 6, because one end of screw rod 3 enters in connecting rod 6 and is fixedly connected with the top of expansion link 8 through the through hole 2 that is arranged on handle 1 middle part, the other end is fixedly connected with fixed block 5, therefore expansion link 8 just can stretch out along the inwall of connecting rod 6 under the effect of spring 7 elastic force, then collet head 10 is aimed at and need to be disassembled with fastening bolt or nut and be inserted in collet head 10, last turning handle 1 can be dismantled with fastening the bolt in putting compared with deep-seated or nut.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
