DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments.

[0023] With reference to Figures 1-4 The utility model discloses a building decoration draws coating device, including trowel 1, the upper welding of trowel 1 has handle 2, the inside of trowel 1 is seted up with containing groove 3, and the inside of containing groove 3 is inserted with telescopic toothed plate 4, the top of telescopic toothed plate 4 is connected with connecting rod 5, the inside of trowel 1 is seted up with the sliding way of being adapted with connecting rod 5, through the setting of sliding way, can satisfy the horizontal movement demand of connecting rod 5 drive telescopic toothed plate 4, to satisfy the drawing coating operation of making texture, in the storage of telescopic toothed plate 4 in the inside of containing groove 3, can satisfy the demand of smooth drawing coating.

[0024] Further, with reference to Figure 3 And Figure 4 It can be known that the outer side of connecting rod 5 is sleeved with sleeve block 6, and the lower side of sleeve block 6 is connected with limiting rod 7, the top of trowel 1 is seted up with two groups of limiting slot of being adapted with limiting rod 7, in the use process, through the mutual cooperation of sleeve block 6, limiting rod 7 and two groups of limiting slot, the telescopic toothed plate 4 of drawing out or storage can be limited.

[0025] Further, with reference to Figure 4 It can be known that the center position of sleeve block 6 is connected with rectangular block 8, the inside of connecting rod 5 is seted up with rectangular slot 9 of being adapted with rectangular block 8, through the mutual cooperation of rectangular block 8 and rectangular slot 9, the vertical guiding operation of sleeve block 6 can be realized, and sleeve block 6 is prevented from accidental loss by external force.

[0026] Further, with reference to Figure 3 And Figure 4 It can be known that the inner wall of rectangular slot 9 is connected with connecting spring 10 vertically, and the bottom of connecting spring 10 is connected with rectangular block 8, through the elastic characteristic that connecting spring 10 itself possesses, the tightness when limiting rod 7 is inserted in the top limiting slot of trowel 1 can be satisfied.

[0027] Further, with reference to Figure 3It can be known that the recess is arranged at the opening position of the accommodating groove 3, and the inner wall of the recess is connected with the fixed shaft 12, the outer side of the fixed shaft 12 is sleeved with the rotating plate 13, and the side edge of the rotating plate 13 is connected with the inner wall of the accommodating groove 3 through the torsion spring 14. When the telescopic tooth plate 4 is accommodated in the accommodating groove 3, the sealing of the opening of the accommodating groove 3 can be realized through the arrangement of the two groups of rotating plates 13, so as to prevent the mortar from entering the inside of the accommodating groove 3. When the telescopic tooth plate 4 is pushed out, the telescopic tooth plate 4 drives the two groups of rotating plates 13 to slide along the outer wall of the fixed shaft 12 under stress, so as to realize the opening operation of the opening of the accommodating groove 3. When the telescopic tooth plate 4 is accommodated, the rotating plate 13 is reset through the elastic force of the torsion spring 14, so as to realize the sealing of the opening again.

[0028] Further, referring to Figure 2 It can be known that the inner wall of the accommodating groove 3 is symmetrically connected with the cross rod 11, and the inside of the telescopic tooth plate 4 is provided with the guide groove matched with the cross rod 11. In the use process, when the telescopic tooth plate 4 moves transversely, the telescopic tooth plate 4 slides along the outer wall of the cross rod 11 under stress, so as to realize the guiding operation of the telescopic tooth plate 4.

[0029] Further, referring to Figure 1 It can be known that the outer side of the handle 2 is sleeved with the rubber sleeve 15, and the outer surface of the rubber sleeve 15 is provided with anti-skid lines.
