More specifically, in the relative sliding direction (the left-right direction in fig. 3) of the first clamping plate 112 and the second clamping plate 122, the two connecting plates 130 are inclined outward, and a large-sized clamping space is formed therebetween. Meanwhile, the two clamping plates 140 are inclined inward, and an entrance having a size smaller than the clamping space is formed between the ends of the two clamping plates 140.

With continued reference to fig. 1 to 4, further, the first clamping plate 112 and the second clamping plate 122 are provided with elastic pads 150 on the sides contacting with the driving component, so that the first clamping plate 112 and the second clamping plate 122 are attached to the driving component. In the clamped state, the elastic pad 150 is pressed by two sides, the side wall contacting with the driving part can be completely jointed with the side wall of the driving part, the curvature of the outer shell of the balance car is automatically formed, and the first clamping plate 112 and the second clamping plate 122 are more jointed with the driving part. The resilient pads 150 are disposed on the inner sides of the first clamping plate 112 and the second clamping plate 122. In this embodiment, the inner side refers to a side of the first clamping plate 112 and the second clamping plate 122 facing the clamping space. Accordingly, the outer side of the first clamping plate 112 and the second clamping plate 122 refers to the side facing away from the clamping space.

In this embodiment, the elastic pad 150 can be selected from a foaming pad, and the foaming pad can automatically form the curvature of the outer shell of the balance car when the first clamping plate 112 and the second clamping plate 122 are connected and clamped with the driving part through the structural gap inside the foaming pad, so that the connecting structure is more attached to the driving part.

With reference to fig. 2 to fig. 3, further, one of the first connecting portion 111 and the second connecting portion 121 is provided with a sliding rail 160, and the other of the first connecting portion 111 and the second connecting portion 121 is slidably connected to the sliding rail 160. For example, the slide rail 160 is provided in the second connection portion 121, and the slide rail 160 and the first connection portion 111 can slide, or the slide rail 160 is provided in the first connection portion 111, and the slide rail 160 and the second connection portion 121 can slide.

Referring to fig. 1 to fig. 3, further, the slide rail 160 and the first connecting portion 111 or the second connecting portion 121 are an integral structure, and the slide rail 160 is formed by folding the edge of the first connecting portion 111 or the second connecting portion 121. In the present embodiment, when the slide rail 160 is disposed at the first connecting portion 111, the slide rail 160 is formed by turning up the edge of the first connecting portion 111, and when the slide rail 160 is disposed at the second connecting portion 121, the slide rail 160 is formed by turning up the edge of the second connecting portion 121.

The integral structure is not limited to integral molding, and may be fixedly connected by welding or the like.

With reference to fig. 2 to fig. 3, further, the length adjustment mechanism 180 includes a quick-release screw 181 and a handle 182, the quick-release screw 181 connects the two limiting blocks 170, and both of the two limiting blocks 170 are provided with threaded holes adapted to the quick-release screw 181. The quick-release screws 181 are inserted into the threaded holes of the two limit blocks 170, and the length of the quick-release screws 181 is adjusted by rotating the handle 182 to adjust the distance between the two limit blocks 170, so that the effect of adjusting the distance between the first clamping plate 112 and the second clamping plate 122 is achieved.

With reference to fig. 2, further, the handle 182 is hinged to the quick-release screw 181 through the rotating shaft 183, the rotating shaft 183 is perpendicular to the quick-release screw 181, and the handle 182 can rotate around the rotating shaft 183, so that after the distance between the first clamping plate 112 and the second clamping plate 122 is adjusted in place, the handle 182 is rotated to be close to the first clamping plate 112 or the second clamping plate 122, and therefore, foreign objects are prevented from being scratched when the balance car frame is used, and potential safety hazards are avoided.

In this embodiment, as shown in fig. 3, the handle 182 is an eccentric handle, one end of the eccentric handle is a hinged end 1821, which is circular in profile and hinged to the quick release screw 181; the other end is a gripping end 1822. When the distance between the first clamping plate 112 and the second clamping plate 122 needs to be adjusted, the holding end 1822 is held by a hand to enable the eccentric handle to drive the quick-release screw 181 to rotate, and the distance between the two limiting blocks 170 is increased or decreased through the threaded matching between the limiting blocks 170 and the quick-release screw 181, so that the distance between the first clamping plate 112 and the second clamping plate 122 is adjusted; when the distance between the first clamping plate 112 and the second clamping plate 122 is adjusted to a predetermined position, the eccentric handle is rotated about the rotating shaft 183 to make the holding end 1822 close to the first clamping plate 112 or the second clamping plate 122, and the hinged end 1821 presses the stopper 170, so that the stopper 170 is locked.

It should be noted that the hinged end of the eccentric handle is eccentrically disposed, and specifically, when the holding end 1822 is close to the first clamping plate 112 or the second clamping plate 122, the distance between the rotating shaft 183 and the outer contour of the hinged end 1821 is greater than the distance between the rotating shaft 183 and the outer contour of the hinged end 1821 when the holding end 1822 and the quick release screw 181 are horizontal. Further, when the holding end 1822 is adjacent to the first jaw 112 or the second jaw 122, the hinged end 1821 abuts the stop block 170, and when the holding end 1822 is horizontal with the quick release screw 181, the hinged end and the stop block 170 are in a clearance fit. Thus, when the gripping end 1822 is pressed down adjacent to the first jaw 112 or the second jaw 122, the hinged end 1821 compresses the stop block 170, thereby locking the stop block 170.

With reference to fig. 1 to fig. 3, further, the first clamping plate 112 and the second clamping plate 122 are provided with a reinforcing rib 190 at the outer side thereof to prevent the first clamping plate 112 and the second clamping plate 122 from being broken under an excessive force or a long-term stress. Specifically, the reinforcing rib 190 may be made of the same material as the first clamping plate 112 and the second clamping plate 122, and may be integrally formed with the first clamping plate 112 or the second clamping plate 122.

Specifically, when the frame needs to be mounted on the driving part, the quick-release screw 181 is detached by using the handle 182, so that the first clamping member 110 and the second clamping member 120 move relatively along the slide rail 160, when the distance between the first clamping member 112 and the second clamping member 122 is larger than that of the driving part, the driving part is placed between the first clamping member 112 and the second clamping member 122, the first clamping member 110 and the second clamping member 120 move back along the slide rail 160, and after the two limit blocks 170 are connected by using the quick-release screw 181, the quick-release screw 181 is screwed by using the handle 182, so that the mounting can be completed. After the installation, the first clamping plate 112 and the second clamping plate 122 can be attached to the outer surface of the driving member by the elastic pad 150, so as to achieve the fastening effect. This mounting means utilizes the handle 182 of taking certainly to drive the quick detach screw 181 and rotates, fastens first holder 110 and second holder 120 then, need not utilize other instruments outside the connection structure, has avoided not having the inconvenience that standby tool caused when needing to install and dismantling, can install and dismantle anytime and anywhere, has broken away from external conditions's restriction.
