Abstract
The utility model discloses a socket spanner. The socket spanner comprises a clamp socket (2). A clamp hole is arranged at the front end of the clamp socket (2). The socket spanner is characterized in that a main force arm (3) perpendicular to the axis of the clamp socket (2) is fixedly connected to the rear end of the clamp socket (2), the other end of the main force arm (3) is movably connected with a rotation arm (6), and a socket (7) is movably sleeved on the rotation arm (6). According to the socket spanner, the structure is simple, the main force arm and the rotation arm are arranged, and the position of the rotation arm changes to enable a nut or a bolt to be screwed up or dismounted rapidly, and the operation speed can be accelerated greatly.
Description
Technical field
The utility model relates to a kind of box spanner, is mainly used in installing and removing nut.
Background technology
In the prior art, the installation and removal of bolt or nut are to adopt common spanner mostly, usually will constantly adjust the position that spanner engages with nut when tightening or unclamp nut, effort and speed are slow, and is especially just more difficult for screw rod long its installation of bolt and dismounting.In construction, often relate to the installation and removal work of a large amount of bolts, nut, owing to use the general tool operating speed slow, therefore often influence construction speed.
Summary of the invention
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of bolt and nut peace that can improve to tear the box spanner of speed open.
The utility model is achieved by the following technical solution: a kind of box spanner, comprise the jig sleeve, the front end of jig sleeve has the jig hole, its special character is, the rear end of described jig sleeve be fixedly connected with one with main force's arm of its axis normal, the other end of described main force arm is connected with a turning arm, and movable sleeve is provided with sleeve on the described turning arm.
In the utility model, turning arm and main force's arm flexibly connect, turning arm is rotatable, when turning arm rotation when being certain angle with main force arm, only with hand is held sleeve on the turning arm and is utilized wrist to rotate can to drive main force's arm by turning arm and rotate continuously, thereby drive the rotation of jig sleeve, realize the screw/unscrew to bolt or nut.When turning arm rotation when consistent with the direction of main force arm, at this moment, main force's arm and the turning arm formation one long arm of force can carry out fastening or make bolt or nut loosening the turning arm application of force bolt or nut.
Be the position of restriction turning arm rotation, an end that is connected with turning arm on the described main force arm is provided with postive stop baffle corresponding to the head of turning arm link.Can limit turning arm and rotate to the arm direction consistent location with the main force by postive stop baffle is set, make more convenient operation.
The beneficial effects of the utility model are: the utility model is simple in structure, it is by arranging main force's arm and rotatable rotary arm at the jig sleeve, when turning arm rotation when being certain angle with main force arm, only need utilize wrist to rotate and to make nut or bolt rotation become a continuous action, thereby the peace that has improved nut or bolt is torn speed open.The utility model is easy to operate, utilizes the evolution of turning arm, and nut or bolt can be tightened or remove fast, can improve operating speed greatly.
Description of drawings
Fig. 1 is the structural representation in the utility model specific embodiment;
Among the figure, 1, the jig hole, 2, the jig sleeve, 3, main force's arm, 4, postive stop baffle, 5, rotating shaft, 6, turning arm, 7, sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of box spanner, comprise jig sleeve 2, the front end of jig sleeve 2 has jig hole 1, and the rear end of described jig sleeve 2 is fixedly connected with main force's arm 3, the axis normal setting of main force's arm 3 and jig sleeve 2, the other end of main force's arm 3 is connected with a turning arm 6 rotationally by a rotating shaft 5, turning arm 6 can rotate around rotating shaft 5, goes back movable sleeve at turning arm 6 and is provided with sleeve 7, can relatively rotate between sleeve 7 and the turning arm 6.
In order to limit the position of turning arm 6 rotations, an end that is connected with turning arm 6 on the described main force arm 3 is provided with postive stop baffle 4 corresponding to the head of turning arm 6 links.Postive stop baffle 4 can limit turning arm 6 and rotate to the arm direction consistent location with the main force.
Using method of the present utility model is: when being used for jack panel or bolt, block the head of nut or bolt with jig hole 1, turning arm 6 rotations 2 places, position extremely as shown in the figure, main force's arm 3 is angled with turning arm 6, at this moment, utilize wrist to rotate fast nut or bolt are screwed onto the position that needs.Then, with turning arm 6 rotations 1 place, position extremely as shown in the figure, turning arm 6 is consistent with the direction of main force's arm, and at this moment, main force's arm 3 and turning arm 6 form a long arm of force, can be with bolt or nut screwing clamping to the turning arm application of force.
When being used for dismounting, block the head of nut or bolt with jig hole 1, turning arm 6 rotations 1 place, position extremely as shown in the figure, the long arm of force elder generation's loose nut or the bolt that utilize main force's arm 3 and turning arm 6 to form, again with turning arm 6 rotations 2 places, position extremely as shown in the figure, at this moment, can utilize wrist to rotate pulls down nut or bolt fast.
Other parts in the present embodiment adopt prior art, do not repeat them here.
Claims (2)
