Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1-3, a symmetrical multi-purpose fixture for spot welder, it includes centre gripping frame 4 and base 13, the welding of top intermediate position department of base 13 has bracing piece 12, the top of bracing piece 12 is rotated through the activity and is connected with fixed block 10, the inside sliding connection of fixed block 10 has four dead levers 7, and the equidistant four spacing fixture blocks 8 that are provided with in the outside of dead lever 7, spacing fixture block 8 and the inside draw-in groove 9 sliding connection who sets up of fixed block 10, the welding of one end of dead lever 7 has gag lever post 6, and the inside threaded connection of gag lever post 6 has first hob 5, the welding of one end of gag lever post 6 has centre gripping frame 4, and the inside of centre gripping frame 4 is connected with clamp plate 1 through spring 2, the top of clamp plate 1 is rotated and is connected with bolt 3, and the inner wall threaded connection of bolt 3.
