At present, motor bike, Electrical Bicycle, bicycle is connected with trailer, have the many advantages of matter-loading amount, carry such as can directly goods being put in the trailer after the shopping, made things convenient for people's life, motor bike, when Electrical Bicycle is connected with trailer with bicycle, need attaching parts, in the existing attaching parts, relatively more commonly used is motor bike, Electrical Bicycle, bicycle and the simple part that directly links to each other of trailer, such as hook etc., make motor bike but the part that directly links to each other such as in the process of riding, link up with, Electrical Bicycle, bicycle is not close, dumb with cooperating of trailer, make motor bike easily, Electrical Bicycle, bicycle causes rollover in turning, vibrations are big in the process of riding, and cause controlling uncomfortable, and the difficulty of riding strengthens.

The utility model content

In view of this, the utility model provides a kind of part of pulling, with solve existing pull cause controlling when preceding vehicles such as motor bike that part in use occurs, Electrical Bicycle, bicycle are connected with trailer uncomfortable, the problem that the difficulty of riding is big.

For achieving the above object, the utility model provides following technical scheme:

A kind of part of pulling comprises: left and right sides rotating shaft, last lower rotary shaft, first fetching, second fetching and link, wherein:

Described first fetching is connected the two ends of described left and right sides rotating shaft, and can rotate with respect to the rotating shaft of the described left and right sides;

Described second fetching is connected described two ends of going up lower rotary shaft, and can rotate with respect to the described lower rotary shaft of going up;

Described upward lower rotary shaft and the rotating shaft of the described left and right sides connect into crosswise by described link.

Preferably, above-mentioned pulling in the part, described link is a screw rod.

Preferably, above-mentioned pulling in the part, the structure of described first fetching and second fetching is the U type.

From above-mentioned technical scheme as can be seen, first fetching that connects left and right sides rotating shaft in the part of pulling among the utility model embodiment is welded on motor bike, the tail end of preceding vehicle such as Electrical Bicycle or bicycle, second fetching of lower rotary shaft is welded on the trailer pipe fitting in the connection, left and right sides rotating shaft can left-right rotation, last lower rotary shaft can rotate up and down, when turning round, pull first fetching in the part with respect to left and right sides rotating shaft left-right rotation, make control in the turning process easier, when the Uneven road thing, second fetching of pulling in the part is rotated up and down with respect to last lower rotary shaft, cushioned the vibrations that Uneven road brings, more comfortable in the feasible process of riding, owing to pull the rotation that part can be regulated rotating shaft according to the situation of riding, solved control in the process of riding uncomfortable, the problem that the difficulty of riding is big.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 pulls part plan structure scheme drawing among the utility model embodiment;

Fig. 2 be among Fig. 1 A-A to structural representation;

Fig. 3 is for pulling the part plan structure scheme drawing that part and Electrical Bicycle are connected with trailer among the utility model embodiment;

Fig. 4 be among Fig. 3 A-A to structural representation.

The specific embodiment

For quote and know for the purpose of, hereinafter label in the accompanying drawing is explained as follows:

1, left and right sides rotating shaft, 2, go up lower rotary shaft, 3, the trailer pipe fitting, 4, the Electrical Bicycle shelf, 5, screw rod, 6, first fetching, 7, second fetching.

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

The utility model embodiment discloses a kind of part of pulling, with solve existing pull preceding vehicles such as motor bike that part in use occurs, Electrical Bicycle, bicycle cooperate with trailer do not cause closely controlling uncomfortable, the problem that the difficulty of riding is big.

The disclosed trailer spare of the utility model embodiment is useful between preceding vehicles such as motor bike, Electrical Bicycle, bicycle and the trailer; can be installed between automobile and the trailer, preceding vehicle can not limit the usage range of pulling part that the utility model is protected yet.

Be example below with the Electrical Bicycle, the part of pulling disclosed in the utility model described in conjunction with Fig. 1-Fig. 4 in the Figure of description.

A kind of part of pulling as Fig. 1-shown in Figure 2, comprising: left and right sides rotating shaft 1, go up lower rotary shaft 2, first fetching 6, second fetching 7 and screw rod 5, wherein:

First fetching 6 is connected the two ends of left and right sides rotating shaft 1, and can rotate with respect to left and right sides rotating shaft 1;

Second fetching 7 is connected the two ends of lower rotary shaft 2, and can rotate with respect to last lower rotary shaft 2;

Last lower rotary shaft 2 and left and right sides rotating shaft 1 are connected by screw rod, and last lower rotary shaft 2 and left and right sides rotating shaft 1 are crosswise.

Screw rod in the above-mentioned holder suspension member can be attaching partss such as screw.
