The scarf is not 'the thread of the externally-circulating ball screw 1 0, dry), H is inserted into the nut 1Q and is connected with the spiral groove (the figure is not attached to the 1 1 system) The number of grooves 1 2 2 of the mosquito parts "1 factory, 12 3 screw the fixing member 12 to the nut ,, the 122 is applied to each reflow element] - the female groove is located in the opposite concave Work 22 towel" so that the mother-reflow element 11 is limited to plastic or teacher, θ 2 'can not fall off, _ set 1 2 can be a spiral ball screw 1 load strength system and nut 1 Q spiral groove spiral The proportional relationship of the volume 'that is, the more the number of spiral coils, the greater the load strength, and the more the work, the more the axial length of the screw m 0 is, the required number of reflow components is the same number =, ' Γ 'fine The fixed part 12 of the reflow element 11 is read in order to avoid the return of the summer! i, it is necessary to pre-produce the m-pieces that are different in different specifications and different specifications! 2 ' g卩 paste is not the mold And the practice 'will increase the number of molds opened and the inventory of the fixed parts 12 itself is more than ^ 2 5 1313332, which in vain adds considerable cost. The conventional fixing member 12 needs to be added. [Invention] Based on the above-mentioned shortcomings of the conventional ball screw, the inventors have been researching and researching, researching and improving, and making sample tests, repeated tests, and improvement, based on years of experience in research and development of related products. The present invention has finally been achieved by the object of the present invention. That is, the main object of the present invention is to provide a solid φ component of a fixed reflow element as a block of a single size so that it can be fixed to adjacent ones. Between the two reflow elements, the same size of the fixing member can be provided between the plurality of reflow elements to fix all the reflow elements, thereby opening only one mold of the size fixing piece and fixing the single size fixing piece, thereby reducing the cost. And the stock pressure. In order to achieve the above object, the present invention is characterized in that it is provided between the reflow elements of the nut of the ball screw, and the upper end surface extends the two wings to be pressed against the reflow element. The lower end forms a bump between the two reflow elements, and the system has a through hole penetrating through the top and bottom for a screw to fix the screw The width of the bump is set to be equal to the distance between two adjacent reflow elements, such that the two sides of the bump abut against the adjacent two reflow elements; the two wings and the two of the bumps The side is set to be parallel with the reflow element - and can be made of plastic material or rubber material.
