[0036] With reference to Figure 3 - Figure 5 The lower portions of the upper fixed plate 43 and the lower fixed plate 44 are fixedly connected with a connecting rod 47, four groups of connecting rods 47 are arranged, the length of the connecting rod 47 fixed to the lower portion of the upper fixed plate 43 is longer, and the connecting rod 47 slides in the inner wall of the moving seat 41, the lower portion of the moving seat 41 is rotatably connected with a supporting seat 45, the four groups of connecting rods 47 are driven to slide in the sliding groove 46 by rotating the supporting seat 45, so that the limiting of the upper fixed plate 43 and the lower fixed plate 44 is released, the upper fixed plate 43 and the lower fixed plate 44 are separated under the elastic force of the compression spring 49, the upper portion of the supporting seat 45 is provided with the sliding groove 46, the sliding groove 46 provides a sliding track for the connecting rod 47, the lower portion of the connecting rod 47 is slidably connected to the inner wall of the sliding groove 46, the inner wall of the front portion of the supporting seat 45 is rotatably connected with a limiting rod 48, the limiting rod 48 is connected to the outer side of the moving seat 41, the opposite side of the upper fixed plate 43 and the lower fixed plate 44 is provided with the compression spring 49, the compression spring 49 applies a force in the opposite direction to the upper fixed plate 43 and the lower fixed plate 44, so that the upper fixed plate 43 and the lower fixed plate 44 are separated from the threaded rod 5.

[0037] With reference to Figure 4 - Figure 6The fixing assembly comprises a limiting column 51 which is slidingly connected to the inner wall of the limiting rod 48, and the upper portion of the limiting column 51 is inserted into the inner wall of the moving seat 41. When the limiting column 51 is inserted into the moving seat 41, the rotation of the limiting rod 48 is limited, thereby fixing the position of the supporting seat 45. The limiting column 51 and the limiting rod 48 are elastically connected through a return spring 53, so as to provide elastic force for the limiting column 51, thereby stably inserting the limiting column 51 into the inner wall of the moving seat 41 and improving the stability of the limiting rod 48. The return spring 53 is arranged on the periphery of the limiting column 51. The lower portion of the limiting column 51 is fixedly connected with a pulling plate 52, which facilitates the medical staff to pull the limiting column 51. The pulling plate 52 is slidingly arranged on the outer side of the limiting rod 48. The lower portion of the upper fixing plate 43 and the upper portion of the lower fixing plate 44 are provided with threaded grooves. The threaded grooves of the upper portion of the upper fixing plate 43 and the lower portion of the lower fixing plate 44 are attached to the outer side of the threaded rod 5. The threaded grooves can be clamped to the outer side of the threaded rod 5, so as to realize quick angle adjustment. The connecting rod 47 on the lower side of the upper fixing plate 43 penetrates and slidingly moves in the inner wall of the lower fixing plate 44. The lower portion of the connecting rod 47 is provided with a spherical shape, so as to slidingly move the connecting rod 47 in the inner wall of the sliding groove 46 and prevent disengagement.

[0038] With reference to Figure 3 , Figure 4 and Figure 7 , the rear portion of the workbench 2 is provided with a limiting assembly. The limiting assembly comprises a limiting block 61 which is slidingly connected to the inner wall of the workbench 2. Under the elastic force of the compression spring two 62, the limiting block 61 can extrude the anti-skid groove on the threaded rod 5, thereby preventing the threaded rod 5 from rotating. The limiting block 61 and the workbench 2 are elastically connected through the compression spring two 62, and are provided with two groups, which can provide upward extrusion force for the limiting block 61. The lower portion of the limiting block 61 is rotatably connected with a pull ring 63, which facilitates the medical staff to pull the limiting block 61 to release the limiting of the threaded rod 5, so that the threaded rod 5 can be steplessly adjusted. The outer side of the threaded rod 5 is provided with an anti-skid groove. The upper portion of the limiting block 61 is provided with a groove. The groove on the upper portion of the limiting block 61 can cooperate with the threaded rod 5 to extrude and limit the threaded rod 5, thereby preventing the threaded rod 5 from rotating when it is not needed to be adjusted. The inner wall of the groove is provided with an anti-skid strip, which enhances the friction between the threaded rod 5 and the anti-skid strip and improves the limiting effect.

[0039] Working principle: when it is needed to quickly adjust the angle of the supporting plate 3 during use, the medical staff pulls the pulling plate 52. The pulling plate 52 drives the limiting column 51 to slidingly move in the inner wall of the limiting rod 48, so that the upper portion of the limiting column 51 is separated from the inner wall of the moving seat 41, thereby releasing the fixing of the limiting rod 48. Then, the supporting seat 45 is rotated. When the supporting seat 45 is rotated, the connecting rod 47 in the sliding groove 46 on the upper portion of the supporting seat 45 is slidingly moved, thereby driving the upper fixing plate 43 and the lower fixing plate 44 to move. At the same time, the compression spring one 49 between the upper fixing plate 43 and the lower fixing plate 44 is in action, so that the upper fixing plate 43 and the lower fixing plate 44 are separated from the outer side of the threaded rod 5.

[0040] At this time, the moving seat 41 is no longer limited by the threaded rod 5 and can slide freely in the inner wall of the workbench 2. When the moving seat 41 slides, the support plate 3 is driven to rotate by the rotatingly connected support rod 42, the angle of the support plate 3 is quickly adjusted to adapt to the general posture requirement of the blood sampling personnel. When the elastic outer rear pull drives the limiting rod 48, the limiting column 51 is inserted into the inner wall of the moving seat 41 again, the support seat 45 is limited, the threaded slots on the upper fixed plate 43 and the lower fixed plate 44 are clamped outside the threaded rod 5, and the angle of the support plate 3 is fixed.

[0041] If the angle of the support plate 3 needs to be adjusted more accurately, the pull ring 63 is pulled, the limiting block 61 drives the elastic force of the compression spring two 62 to separate the upper groove of the limiting block 61 from the outer anti-skid groove of the threaded rod 5, and the extrusion limiting of the threaded rod 5 is released.

[0042] Subsequently, the threaded rod 5 is rotated, the threaded slots on the upper fixed plate 43 and the lower fixed plate 44 are attached to the outer side of the threaded rod 5, the threaded rod 5 is rotated, the upper fixed plate 43 and the lower fixed plate 44 are moved axially along the threaded rod 5, the angle of the support plate 3 is accurately adjusted through the support rod 42, stepless adjustment is realized, and the individualized requirement of different blood sampling personnel is met.

[0043] Finally, it should be noted that: the above only describes preferred embodiments of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
