Abstract
The utility model discloses a wrench for joints of a folding bike. The wrench comprises a handle including an outer handle and an inner handle, wherein a bike rotating shaft mounting hole is formed on the outer handle and a wrench rotating shaft mounting hole is formed on the inner handle, and the centers of the bike rotating shaft mounting hole and the wrench rotating shaft mounting hole deviate; a wrench rotating shaft and a screw rod are arranged in the wrench rotating shaft mounting hole, the screw rod is guided by a locating slot and a jackscrew is arranged on the wrench rotating shaft, and an inner hexagon is arranged at the tail end of the threads of the screw rod. The utility model has the benefits of practicability, low manufacturing cost, convenient use, labor conservation when assembling the folding bike, and safer assembled bicycle.
Description
Technical field
The utility model relates to a kind of spanner, and particularly a kind of folding bicycle closes saves spanner.
Background technology
Because the folding bicycle occupation space is little, the people that use are also more and more, when using folding bicycle, can use spanner and tighten the connection of the joint part of bicycle, present general this kind spanner is in the middle of the process of using, can't form integrative-structure with bicycle body, eccentric handle is free to rotate to any angle on car body, has potential safety hazard, and is very much effort when using.
The utility model content
At existing shortcoming, the utility model provides a kind of novel folding bicycle to close and saves spanner.
To achieve these goals, the measure taked of the utility model:
A kind of folding bicycle closes saves spanner, comprise handle, described handle is divided into outdoor handle and inner handle, have car body rotating shaft installing hole on the outdoor handle, inner handle is provided with spanner rotating shaft installing hole, and has an off-centre between the center of described car body rotating shaft installing hole and spanner rotating shaft installing hole;
In the described spanner rotating shaft installing hole spanner rotating shaft and screw rod are housed, screw rod leads by locating slot, and the spanner rotating shaft is provided with jackscrew, and the screw flight end is provided with interior hexagonal.
The beneficial effects of the utility model: practicality, production cost is low, and is easy to use, and in the time of the locking folding bicycle, more laborsaving, the bicycle that installs is safer.
Description of drawings

Fig. 2, side structure schematic diagram of the present utility model.
The specific embodiment
A kind of folding bicycle closes saves spanner, comprise handle, described handle is divided into outdoor handle 1 and inner handle 2, have car body rotating shaft installing hole 7 on the outdoor handle 1, inner handle 2 is provided with spanner rotating shaft installing hole 8, and has an off-centre between the center of described car body rotating shaft installing hole 7 and spanner rotating shaft installing hole 8; In the described spanner rotating shaft installing hole 8 spanner rotating shaft 4 and screw rod 5 are housed, screw rod 5 is by locating slot 9 guiding, and spanner rotating shaft 4 is provided with jackscrew 6, and the screw tip of screw rod 5 is provided with interior hexagonal 10.
In the middle of the use of reality process of the present utility model, can come the locking part stroke in mobile bicycle joint by hexagonal in the rotary screw 10, set the clamping force in bicycle folding joint, wherein, jackscrew 6 can hold out against regulate go into after screw rod 5, prevent that screw rod 5 from becoming flexible in spanner rotating shaft 4; Forming an off-centre between car body rotating shaft installing hole 7 and the spanner rotating shaft installing hole 8, because spanner is to be fixed on the car body by hole 7, is the pivot of spanner.When the utility model is in releasing orientation, the center of spanner rotating shaft installing hole 8 is lower than the center of car body rotating shaft installing hole 7, with hole 7 is that the pivot of spanner clockwise rotates the time of the present utility model, because eccentric center changes, pulling has screw rod 5 guiding spanner rotating shafts 4 rotations to do the axial motion that the bent axle motion drives screw rod 5, otherwise in the time of backwards rotation, screw rod 5 resets; Unclamp, locking then is that the axially-movable by screw rod 5 reaches the purpose of unclamping and locking, thereby realizes this practical purpose.
Those skilled in the art's simple change and replacement in this area all are within the protection domain of the present utility model.
