Description

A kind of telescopic sleeve spanner
Technical field
The utility model relates to a kind of spanner, and specifically a kind of telescopic sleeve spanner, belongs to machine tool technical field.
Background technology
Box spanner is made up of the sleeve of multiple band hexagon ring or 12 corner apertures and the multiple component such as handle and connecting rod, be specially adapted to dismantle and fastening residing for the bolt of the very narrow or very depths of caving in, space or nut.
Often need to use box spanner to carry out dismounting and fastening to bolt or nut in machine work.In production and life, the length of widely used box spanner connecting rod is all generally fixing at present, cannot dismantle and the fastening bolt or the nut that are in different depth position, the box spanner often needing workmen to carry multiple different length specification just can complete dismounting and fasteningly be in the bolt of different depth position or the task of nut, so not only increase use cost, and increase the labour intensity of personnel, 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 structure simple, easy to use, and the adjustable telescopic sleeve spanner of length of 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 telescopic sleeve spanner, comprise handle, connecting rod, spring, expansion link, collet head, trip bolt, tapped through hole, chute, chamfering, it is characterized in that: one end of described connecting rod is fixedly connected with the middle part of handle is vertical, the bottom of connecting rod is provided with tapped through hole, trip bolt is provided with in tapped through hole, spring and expansion link is provided with in connecting rod, the both sides of expansion link are provided with chute, trip bolt is through tapped through hole and embedding is arranged in the chute of expansion link both sides, the lower end of expansion link is provided with chamfering, expansion link is connected by the top of the chamfering with collet head that are arranged on lower end, the length of expansion link (4) is greater than the length of chute (8), the width of chute (8) is greater than the diameter of the screw rod of trip bolt (6), trip bolt (6) through tapped through hole (7) and embed be arranged in the chute (8) of expansion link (4) both sides.
The drift of described spring is greater than the length of described connecting rod.
The width of described chute is greater than the diameter of the screw rod of described trip bolt, and object trip bolt can be allowed to pass tapped through hole and embed be arranged in the chute of expansion link both sides.
Described trip bolt is through tapped through hole and embedding is arranged in the chute of expansion link both sides, and object prevents expansion link from coming off in connecting rod.
Compared with prior art, the utility model has following beneficial effect: structure is simple, easy to use, can the length of regulating sleeve spanner connecting rod in a big way, thus can dismantle and the fastening bolt or the nut that are in different depth position, effectively reduce the quantity of the box spanner carried required for personnel, not only can reduce use cost, and the labour intensity of personnel can be reduced, be conducive to increasing work efficiency.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is stereochemical structure exploded perspective view of the present utility model.
In figure: 1-handle, 2-connecting rod, 3-spring, 4-expansion link, 5-collet head, 6-trip bolt, 7-tapped through hole, 8-chute, 9-chamfering.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of telescopic sleeve spanner, comprise handle 1, connecting rod 2, spring 3, expansion link 4, collet head 5, trip bolt 6, tapped through hole 7, chute 8, chamfering 9, it is characterized in that: one end of described connecting rod 2 is fixedly connected with the middle part of handle 1 is vertical, the bottom of connecting rod 2 is provided with tapped through hole 7, trip bolt 6 is provided with in tapped through hole 7, spring 3 and expansion link 4 is provided with in connecting rod 2, the both sides of expansion link 4 are provided with chute 8, trip bolt 6 is through tapped through hole 7 and embedding is arranged in the chute 8 of expansion link 4 both sides, the lower end of expansion link 4 is provided with chamfering 9, expansion link 4 is connected with the top overlapping simple 5 by the chamfering 9 being arranged on lower end, the length of expansion link 4 is greater than the length of chute 8, the width of chute 8 is greater than the diameter of the screw rod of trip bolt 6, trip bolt 6 also embeds through tapped through hole 7 and is arranged in the chute 8 of expansion link 4 both sides.
The drift of described spring 3 is greater than the length of described connecting rod 2.
The width of described chute 8 is greater than the diameter of the screw rod of described trip bolt 6, and object trip bolt 6 can be allowed through tapped through hole 7 and embed be arranged in the chute 8 of expansion link 4 both sides.
Described trip bolt 6 is through tapped through hole 7 and embedding is arranged in the chute 8 of expansion link 4 both sides, and object prevents expansion link 4 from coming off in connecting rod 2.
When need dismounting and fastening be in compared with the bolt of deep location or nut time, first unclamp trip bolt 6, described expansion link 4 just can stretch out connecting rod 2 under the elastic force effect of spring 3, then manual adjustments expansion link 4 stretches out the length of connecting rod 2, finally screw trip bolt 6 and can lock expansion link 4, thus reach dismounting and the fastening object being in bolt compared with deep location or nut.
When need dismounting and fastening be in bolt or the nut of more shallow position time, first unclamp trip bolt 6, described expansion link 4 just can stretch out connecting rod 2 under the elastic force effect of spring 3, then manual compression by expansion link 4 enters in connecting rod 2, screw trip bolt 6 simultaneously and can lock expansion link 4, thus reach dismounting and be fasteningly in the bolt of more shallow position or the object of nut.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from 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.
