DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-3 The utility model provides a technical solution: a handle sub-assembly welding jig, comprising a shell 1, a through hole 12 is opened from top to bottom in the middle of the shell 1, an inner chamber 11 is extended downward from the top of the shell 1, a guide column 23 is fixed to the inner wall of the bottom of the inner chamber 11 by welding, and a handle fixing arm 2 is slidably installed on the top of the two guide columns 23, and the handle is placed on the handle fixing arm 2 by extending the lock core into the through hole 12, so as to locate the position of the handle, which is convenient for welding;
[0019] An extended table is provided at the top of the handle fixing arm 2, and an insertion hole 22 is provided at the bottom of the handle fixing arm 2. Oblique clamping blocks 21 are evenly fixed to the side walls of the handle fixing arm 2 by welding. The oblique clamping blocks 21 are arranged in a straight line from top to bottom. When adjusting, different height positioning effects are formed by different oblique clamping blocks 21.
