The specific embodiment

As shown in Figure 1 and Figure 2, the utility model system is for being installed on the electric cycle 50.The utility model comprises base 10, main strut 20, adjusting lever 30 and is connected in fixed sturcture 40 on the main strut 20.

Base 10 is the U font and for being connected on the electric cycle 50, it has the bottom surface 11 that supplies to be connected on the electric cycle 50 and reaches toward each other and the two sides 12 that gone out by bottom surface 11 vertical extent.

As Fig. 1, shown in Figure 5, the bottom of main strut 20 system is hubbed at 12 of the two sides of base 10, and its top can be in conjunction with handle 21.

The bottom system of adjusting lever 30 is hubbed at 12 of base 10 two sides, its top and fixed sturcture 40 windings.

Fixed sturcture 40 comprises permanent seat 41, two locating dowel pins 42, block set 43, connecting pipe 44, sliding sleeve 45, elastic element 46, two wedge shape fixture blocks 47 and pull handle 48.

Permanent seat 41 is two to be fixedly arranged on the plates 410 on the main strut 20 toward each other and respectively, and each plates 410 is respectively equipped with corresponding perforation 411.

Block set 43 is for being arranged at the hollow tube of 410 of 41 liang of plates of permanent seat, which is provided with pin-and-hole 431, central hole 433 that corresponds respectively to perforation 411 and the screw 432 of being located at central hole 433 bottoms.Block set 43 is positioned on the permanent seat 41 by running through the locating dowel pin 42 that places in the pin-and-hole 431 after the perforation 411.

Connecting pipe 44 is that an end is provided with correspondence and is screwed together in the hollow tube of the external thread section 441 in block set 43 screws 432, and its other end is provided with two fixture block respect to one another holes 442.Connecting pipe 44 is screwed together in its external thread section 441 in the screw 432 of block set 43, so as to being incorporated on the block set 43.

Adjusting lever 30 is mounted in the connecting pipe 44 slidably, and the central hole 433 of connecting pipe 44 and block set 43 can be run through in its top, so that adjusting lever 30 is located in connecting pipe 44 and the block set 43 slidably.

Sliding sleeve 45 is to be mounted on slidably on the connecting pipe 44, which is provided with two elongated slots that correspond to each other 451 and be positioned at its bottom ring inclined-plane 452.

Elastic element 46 ring sets are located on the connecting pipe 44, and the one end is resisted against block set 43, and its other end is resisted against on the sliding sleeve 45, to provide sliding sleeve 45 back stretch.

Each wedge shape fixture block 47 is located at respectively in the connecting pipe 44 fixture block holes 442, and its part of protruding fixture block hole 442 is provided with the inclined-plane 471 that contacts with ring inclined-plane 452 in the sliding sleeve 45.

Pull handle 48 is the U font, and it has two pivot arms, 481, two pivot arms 481 and is respectively equipped with the end that is hubbed at main strut 20 and is mounted on dome piece 482 in sliding sleeve 45 elongated slots 451 slidably.

As Fig. 2, shown in Figure 5, when not adjusting state, sliding cover 45 under the elastic force of elastic element 46, make sliding sleeve 45 by itself and wedge shape fixture block 47 ramps 471 contacted in ring inclined-planes 452 wedge shape fixture block 47 pushed in the fixture block hole 442 with clamping adjusting lever 30 reach the fixedly relative position of main strut 20 and adjusting lever 30.

As Fig. 3, Fig. 4, shown in Figure 5, when adjusting handle 21 angle states, earlier pull handle 48 is upwards pivoted towards anticlockwise direction, so that sliding sleeve 45 moves to block set 43, while compression elastic element 46, wedge shape fixture block 47 can be free to slide adjusting lever 30 because of being subjected to sliding sleeve 45 compressings at this moment, with the relative position of adjusting main strut 20 and adjusting lever 30 after angle as shown in Figure 4, discharge sliding cover 45 under the elastic force that pull handle 48 makes elastic element 46, make the inclined-plane 471 of sliding sleeve 45 via the 452 compressing wedge shape fixture blocks 47 of ring inclined-plane in it, once again with 47 packings of wedge shape fixture block with clamping adjusting lever 30, to reach the fixedly purpose of the relative position of main strut 20 and adjusting lever 30.
