[0006] As a further description of the above technical scheme:

[0007] Two section positioning sleeve are all circular tubes, and the axis of two section positioning sleeve coincides.

[0008] As a further description of the above technical scheme:

[0009] Open circular tube is against the inner wall of two section positioning sleeve, and open circular tube is against the inner wall of open card piece.

[0010] As a further description of the above technical scheme:

[0011] Locking piece includes screw rod, support sleeve and eccentric wheel wrench, screw rod passes through both ends of open card piece, eccentric wheel wrench is screwed at the end of screw rod, support sleeve is set up on screw rod, and both ends of support sleeve are respectively against open card piece and eccentric wheel wrench.

[0012] As a further description of the above technical scheme:

[0013] The end of support sleeve is provided with arc surface, and the surface of eccentric wheel wrench is attached to arc surface.

[0014] As a further description of the above technical solution:

[0015] A buffer pad is provided between the support sleeve and the end portion of the opening clamp.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In the utility model, the opening of the opening clamp is tightened by triggering the locking member to squeeze the open round tube, and the tightening of the open round tube squeezes the head and leg board plugs, thereby slowly locking the head and leg board plugs in two stages. The compression and friction of the open round tube on the head and leg board plugs is used to avoid abrupt locking, thereby avoiding locking failure. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-5The utility model provides a technical scheme: a locking device for operating table head leg plate, including two section positioning sleeve 1, open circular tube 2, open clamping piece 3, locking piece 4 and head leg plate plug 5, two section positioning sleeve 1 is installed on fixed frame 6, open circular tube 2 passes through two section positioning sleeve 1, open clamping piece 3 is set on open circular tube 2, and open clamping piece 3 is located between two section positioning sleeve 1, locking piece 4 is installed in both ends of open clamping piece 3, head leg plate plug 5 is inserted in open circular tube 2,
