Referring to fig. 1-4, an embodiment of the present invention is shown:

a multi-functional replaceable head painting knife comprising:

the frame body 1 comprises a knife handle 11, a thread groove 12 is formed in the surface of the knife handle 11, a drawing knife head 13 is inserted and connected to the inner side of the knife handle 11, and the thread groove 12 formed in the surface of the knife handle 11 increases the friction force of the surface of the knife handle 11, so that the anti-skid performance of a user when holding the knife handle 11 is guaranteed;

fixed establishment 2, fixed establishment 2 includes connecting plate 21, connecting plate 21 fixed connection is on the surface of handle of a knife 11, connecting plate 21's inboard is inserted and is established and be connected with screw rod 22, screw rod 22 has fixed plate 23 through pivot swing joint, the fixed surface of fixed plate 23 is connected with fixed column 24, the fixed surface swing joint of fixed column 24 has movable jack-post 25, the surface of movable jack-post 25 is connected with first movable rod 26, the surface swing joint of movable jack-post 25 has second movable rod 27, the surface of second movable rod 27 is connected with connecting spring 28, spacing groove 29 has been seted up on the surface of drawing tool bit 13, be through pivot connection fixed plate 23 through screw rod 22, thereby when guarantee rotatory screw rod 22, fixed plate 23 can not take place rotatoryly.

Further, the connecting plates 21 are symmetrically distributed on the surface of the tool holder 11 in two groups, screw grooves are formed in the surfaces of the connecting plates 21, and when the screw 22 is rotated, the screw 22 rotates in the screw grooves, so that the screw 22 is displaced in the horizontal direction.

Further, the screw 22 is movably connected to the inner side of the connecting plate 21 through a screw groove, the limiting groove 29 is uniformly formed on the surface of the painting blade 13, and when the second movable rod 27 is engaged with the inner side of the limiting groove 29, the position of the painting blade 13 is limited, so that the painting blade 13 is fixed to the inner side of the holder 11.

Further, one end of the connection spring 28 is connected to the surface of the second movable rod 27, and the other end of the connection spring 28 is connected to the surface of the fixed plate 23, so that the connection spring 28 has certain elasticity, thereby ensuring that the connection spring 28 pulls the second movable rod 27 and the second movable rod 27 is kept at the same position under the condition that the first movable rod 26 is not subjected to an external force.

Further, the inner side surface of handle of a knife 11 is connected with protection machanism 3, protection machanism 3 includes first support and closes spring 31, first support closes spring 31 and connects the inner side surface at handle of a knife 11, first support closes spring 31 and keeps away from the one end surface of handle of a knife 11 and is connected with rubber slab 32, the inner side surface of handle of a knife 11 is connected with second support and closes spring 33, the surface that second support closed spring 33 is connected with and supports and close piece 34, it has certain elasticity to close spring 31 through first support, thereby guarantee rubber slab 32 supports the stability when closing drawing tool bit 13.

Further, first support and close spring 31 evenly distributed at the inboard surface of handle of a knife 11, support and close the surface of piece 34 and be the arc shape, be the arc shape through the surface that supports and close piece 34 to the guarantee draws under the tool bit 13 and inserts when handle of a knife 11 is inboard, draws tool bit 13 and supports and close piece 34, thereby makes the second support close spring 33 and takes place the shrink, and then the stability when guaranteeing that the second supports and closes the piece 34 that supports that spring 33 connects and support and close drawing tool bit 13.

The working principle is as follows: the painting tool bit 13 is inserted into the inner side of the knife handle 11 by a user, so that the surface of the painting tool bit 13 abuts against the first movable rod 26, the second movable rod 27 is driven to rotate, when the second movable rod 27 is clamped in the inner side of the limiting groove 29, the position of the painting tool bit 13 is limited and fixed, when the painting tool bit 13 needs to be replaced, the user drives the fixed plate 23 to move towards one side far away from the surface of the painting tool bit 13 in the horizontal direction by rotating the screw rod 22, so that the second movable rod 27 is not inserted into the inner side of the limiting groove 29 any more, the position of the painting tool bit 13 is convenient to move, the painting tool bit 13 is replaced, the fixed plate 23 is connected with the connecting plate 21 through a telescopic rod, the telescopic length of the telescopic rod is limited, and when the rotary screw rod 22 moves, the moving range of the fixed plate 23 is limited, thereby limiting the moving range of the movable shaft column 25 and ensuring that the second movable rod 27 can be normally positioned at the inner side of the limiting groove 29.

Insert when establishing the inboard at handle of a knife 11 through drawing tool bit 13, first butt closes spring 31 and has certain elasticity, thereby guarantee first butt close the surface that closes drawing tool bit 13 of tightly abutting of rubber slab 32 that spring 31 connects, when drawing tool bit 13 and insert the inboard bottom of establishing handle of a knife 11, thereby make the second butt close spring 33 take place deformation, and then make to abut and close the piece 34 and abut and close the surface of drawing tool bit 13, thereby fix the position of drawing tool bit 13, thereby the guarantee is drawn tool bit 13 and is inserted the stability of establishing behind handle of a knife 11 inboard.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
