When the pushing sheet body 1 is pushed by the prying screw, under the action of the wear-resistant plastic plate 2, the pushing sheet body 1 is prevented from influencing the service life due to abrasion, the friction factor of the wear-resistant plastic plate 2 is smaller, so that the friction force between the prying screw and the wear-resistant plastic plate 2 is smaller, the pushing sheet body 1 is convenient to incline, the prying screw is gradually reduced in increasing amount of the force applied to the pushing sheet body 1 due to the fact that the pushing sheet body 1 is elliptical, the force applied by the prying screw is relatively smaller under the condition that the pushing sheet body 1 is inclined at the same angle with the existing pushing sheet, so that the force applied by a user is reduced, besides, under the action of the ball 9 and the sponge layer 10, a lubricant is coated on the surface of the prying screw, the friction force between the prying screw and the inner side face of the mounting hole 102 is reduced, and the force applied by the user is further reduced, providing convenience for the user.
When pushing away wear-resisting plastic slab 2 on piece body 1 surface and prizing and dialling the screw and prizing when the percutaneous pedicle of vertebral arch screw collision extrusion, elasticity is restoreed ball 11 and can be played the cushioning effect to dynamics when the collision, make wear-resisting plastic slab 2 can not damaged easily, when wear-resisting plastic slab 2 is damaged, the wax stone 3 on elasticity non-woven fabrics 7 surface can be damaged thereupon, the inside polyethylene powder 4 of elasticity restoration ball 11, high wear-resisting carbon black 5, the mixture of molybdenum dioxide 6 and gluing agent can extrude elasticity non-woven fabrics 7 through going out the jiao Kong, fill wear-resisting plastic slab 2's damaged department, treat after the mixture drying solidification, can realize wear-resisting plastic slab 2's repairing function, prolong this wear-resisting plastic slab 2's life.
In this pushing sheet body 1 use, can produce and rock, the inside carbonated water 13 of clean ball 14 can be because of rocking and produce a large amount of gases, thereby burst clean ball 14, make inside cleaner 12 of clean ball 14 and carbonated water 13 flow, cleaner 12 can wash the dust of pushing sheet body 1 both sides, carbonated water 13 has weak alkaline therefore has certain disinfection function simultaneously, can play the disinfection effect to pushing sheet body 1, guarantee the cleanliness of pushing sheet body 1, after pushing sheet body 1 is clean, replenish clean ball 14 in standing groove 103 again, in order to be ready for next use.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
