The purpose of this utility model is to be achieved by following proposal;
The telescopic bag of braces of the present utility model, it comprises knapsack, braces, and described knapsack is provided with the device that can make braces retraction and the device of braking, and the restoring device of described knapsack is provided with runner, mandrel, clockwork spring; The brake apparatus of described knapsack is provided with tension spring shaft, extension spring, brake block, fixed axis; The retraction and the two sides of brake apparatus preferably also are provided with two outer covers, so that will bounce back and brake apparatus is installed on its inside.
The utility model has the advantages that:
1, simple in structure, be easy to make;
2, easy to use, with low cost.
Description of drawings
Fig. 1 is an embodiment overall schematic of the present utility model;
Fig. 2 is the flexible apparatus structure schematic diagram of braces that makes of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
In Fig. 1, the telescopic bag of braces of the present utility model, it comprises knapsack 1, braces 2, described knapsack 1 is provided with the device 3 that can make braces retraction and braking, the two sides of retraction and brake apparatus 3 preferably also is provided with two outer covers 11, be installed on its inside so that will bounce back with brake apparatus 3, outer cover 11 also is provided with installing hole, can rivet with knapsack 1 like this; The restoring device of described knapsack 1 is provided with runner 4, mandrel 5, clockwork spring 6, and mandrel 5 is fixed in the outer cover 11, and runner 4 centers are installed on the mandrel 5, clockwork spring 6 one ends are fixed on the mandrel 5, one end is fixed on the runner 4, and braces 2 is coiled on the runner 4, and runner 4 outer rims are gear shape; The brake apparatus of described knapsack 1 is provided with tension spring shaft 7, extension spring 8, brake block 9, fixed axis 10, fixed axis 10 is fixed in the outer cover 11, brake block 9 is installed on the fixed axis 10, but can be that rotate at the center with fixed axis 10, extension spring 8 one ends draw motion block 9 one ends and are fixed on the tension spring shaft 7, and brake block 7 one ends be the shape that can mesh with runner 4; In the time will elongating braces 2, available hand upwards pushes away an end (in outer cover 11 outsides) of brake block 7, the other end of brake block 7 separates with runner 4 like this, has not just braked, with the braces 2 that is coiled on the runner 4 being pulled out when pulling, but take-off the brake piece 7 when moving suitable length to, because the effect of extension spring 8 makes an end of brake block 7 pull to runner 4, this moment, brake block 7 closed up with runner 4, and engagement has just been braked, runner 4 can't be rotated, reach the purpose of braking braces 2; If allow braces 2 bounce back, also available hand upwards pushes away brake block 7 one ends toward (in outer cover 11 outsides), but does not spur braces 2, because clockwork spring 5 has gathered energy when braces 2 is drawn out, institute is so that runner 4 revolutions also just make braces 2 retractions, and this design principle is the same with ordinary tape measure.
