Figure 5 As shown, a support plunger countersunk hole 41 for connecting a floating spring 5 is provided at the bottom end of the support plunger 4, and the bottom end of the floating spring 5 is fixed by an adjusting screw plug 7. The support plunger 4 slides axially under the action of the floating spring 5, and after contacting the workpiece 9, the support plunger 4 still rises to the end of the stroke, and the raised spring force load is applied to the workpiece 9, and the adaptive height difference reaches a horizontal state; the locking mechanism includes a locking chuck 2 and a limit spring 6, and the bottom end of the locking chuck 2 is symmetrically installed on the outer cylindrical surface of the support seat 1 along the axial direction by 180° through the limit spring 6, and the upper end is connected to the support seat 1 through a locating pin 3, and is provided with a toothed portion 23 that engages with the surface of the support plunger 4, so as to realize the engagement and fixation of the support plunger 4 and perform axial limiting.

[0021] Without replacing other parts, the position of the adjusting screw plug 7 is changed to control the elastic deformation of the floating spring 5 , thereby controlling the supporting force of the supporting plunger 4 on the workpiece 9 .

[0022] The outer cylindrical surface of the support plunger 4 is symmetrically provided with a groove track for connecting the limit screw 8 along the axial direction to control the limit position of the activity of the support plunger 4.
