[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the utility model, it is to be explained that, unless there is definite stipulation and limitation, the term "connects", "connects" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connects, can be mechanical connection, also can be electrical connection, can be direct connection, also can indirectly connect through intermediate medium.

[0023] As shown in the accompanying Figure 1 The technical scheme is mainly aimed at cylindrical or planar products that need to be transported by dovetail table, and the connection mode between the dovetail table and the product is the same as the prior art, and welding or integrated design of the product can be used, and the design of the upper end of the dovetail table can be flat or arc-shaped according to the needs of the product.

[0024] Therefore, the main body of the device of the technical scheme is the connecting base 1, four positioning countersunk holes 11 are arranged at the upper end of the connecting base 1, and the connecting base 1 is fixed or welded on the vehicle or other shelves by screws, so that the device and the vehicle body form a fixed connection.

[0025] The mounting groove 2 is arranged on the connecting base 1, the cross section of the mounting groove 2 is dovetail-shaped, the mounting groove 2 is provided with a flared mouth 21 at the front end, which is mainly used for guiding, so that the dovetail table can smoothly enter the mounting groove 2, and the mounting groove 2 is provided with a positioning plate 5 at the rear end through bolt fixing.

[0026] The fixing slide 3 is arranged on the connecting base 1 and is at a certain angle with the mounting groove 2, and the optimal state is perpendicular, because the contact area is wider, the fixing effect is better, the pushing slide block 4 is slidably connected in the fixing slide, which is used for transversely fixing the dovetail table, and the fixing slide is in an open state at both ends.

[0027] The side plate 6 is fixed on the side of the connecting base 1 by four screws, spring washers and flat washers, and the pushing screw 7 is screwed in the middle of the side plate 6, and the pushing screw 7 is connected with the pushing slide block 4, which is used to control the forward and backward movement of the pushing slide block 4 in the fixing slide 3.

[0028] At the same time, the fixing slide is symmetrically arranged on the left and right sides of the mounting groove 2, when the position on the carrier is not enough, thereby affecting the screwing of the pushing screw 7, the side plate 6 can be removed together with the pushing screw 7 and the pushing slide block 4, and assembled to the other side of the connecting base 1.

[0029] Meanwhile, in order to facilitate the dismounting of the pushing screw 7 and the pushing slider 4, the pushing screw 7 and the pushing slider 4 are detachable, the pushing slider 4 is provided with a convex connection groove 41, the pushing screw 7 is provided with a convex connection block 71, and the pushing screw 7 and the pushing slider 4 are connected through clamping.

[0030] The use process of the utility model is:

[0031] 1. First, screw the pushing screw 7 into the side panel 6, then put the pushing slider 4 into the fixed sliding groove corresponding to the dovetail groove of the connecting base 1, then embed the head of the convex connection block 71 of the pushing screw 7 into the corresponding convex connection groove 41 of the pushing slider 4, push the pushing slider 4 to make the side panel 6 tightly contact the corresponding mounting position of the connecting base 1, fix with four screws, spring washers and flat washers, and fix the positioning plate 5 on the connecting base 1 with screws.

[0032] 2. Install the whole on the vehicle body or other shelves through the four positioning countersunk holes 11.

[0033] 3. When installing the dovetail table, put the dovetail table into the horn mouth 21 of the connecting base 1, push the dovetail table into the mounting groove 2 of the connecting base 1 until it is blocked by the positioning plate 5,

[0034] 4. Turn the pushing screw 7 to make the pushing slider 4 enter the dovetail table gap on the product and clamp tightly until it cannot be turned, so as to fix the product. Since the contact surface of the pushing slider 4 and the dovetail table gap has a taper, under the action of the pushing screw 7, the article cannot be moved in three dimensions.

[0035] 5. When taking out the product, loosen the pushing screw 7 to make the pushing slider 4 exit the dovetail table gap of the article, and take out the product in the opposite direction of the installation.

[0036] According to the above operation process, the device can realize quick installation and fixation, and when the product needs to be taken out, the fixation can be quickly cancelled, and the product can be taken out
