[0002] like Figure 1 The contact 8 shown includes a bracket, an upper contact piece and a lower contact piece. The upper contact piece and the lower contact piece are installed on the bracket. The upper contact piece and the lower contact piece are suitable for elastic opening and closing on the bracket. The front side of the upper contact piece and the lower contact piece form a front socket 81, and the rear side forms a rear socket 82.

[0003] like Figure 2 The chassis component 9 shown is a part of the switch cabinet drawer frame. The chassis component 9 includes a chassis, and a plurality of mounting positions are provided on the chassis for mounting contacts 8. Each mounting position is fixed with a drawer seat external busbar 91. When mounting the contact 8 on the chassis, it is necessary to open the rear socket 82 of the contact 8 and then plug it with the drawer seat external busbar 91, so that the rear socket 82 of the contact 8 clamps the drawer seat external busbar 91.

[0004] During the manufacturing process of the chassis component 9, each contact needs to be installed in the mounting position of the chassis. Since the contact is a part that opens and closes elastically, it is currently operated manually, and the following problems mainly exist: First, the operator holds a pliers-like auxiliary tool with both hands, clamps the contact by manpower and puts it into the mounting position of the chassis, and the operator needs to visually inspect the relative position of the workpiece and the mounting position; Second, long-term operation can easily lead to worker fatigue, affecting production efficiency and is not suitable for female operators to operate; Third, since it is a manual operation, it is impossible to accurately control the strength, and if the force is small, the parts will not be opened enough and cannot be installed; if the force is too large, the spring will be over-stretched and cannot meet the design life.

[0055] The sliding sleeve is used to increase the guiding performance of the clamping seat on the base 1.

[0056] As a preferred embodiment of this embodiment, the base 1 is fixedly connected to the front clamping base 2 .
