DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0038] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "set", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application should be understood according to the specific circumstances.

[0039] As Figures 1-4As shown in the figure, an angle adjusting device of a gypsum board cutting saw includes: a base 1, a gear strip 2, a sliding rail 3, a sliding roller 4, a sliding plate 5, a transmission rod 6, an auxiliary gear 7, a clamping base 8; the gear strip 2 is arranged on the base 1, the gear strip 2 is arc-shaped, the sliding rail 3 is arranged on one side of the gear strip 2, one end of the sliding roller 4 is embedded in the sliding rail 3, the other end of the sliding roller 4 is installed on the sliding plate 5, one end of the transmission rod 6 is fixedly connected with the sliding plate 5, the auxiliary gear 7 is located above the gear strip 2, and the auxiliary gear 7 is sleeved on the transmission rod 6; when the sliding plate 5 is pushed, the sliding roller 4 will roll in the sliding rail 3, and the auxiliary gear 7 will roll on the gear strip 2; since the auxiliary gear 7 is engaged with the gear strip 2, the auxiliary gear 7 can provide resistance for rolling, and can prevent the sliding roller 4 from starting to slide downward due to gravity after stopping rolling. The clamping base 8 is fixedly installed on the other end of the transmission rod 6, and the clamping base 8 is arranged to provide support for the installation of the sliding plate 5 by providing support for the auxiliary gear 7; the embedded arrangement of the sliding roller 4 and the support of the auxiliary gear 7 make the installation of the sliding plate 5 and the clamping base 8 more stable.

[0040] As shown in the figure, Figure 1 In order to be able to install the cutting saw, a clamping mechanism is designed, which includes two clamping grooves 9 arranged symmetrically on the clamping base 8, a first screw rod 10 arranged in the two clamping grooves 9, two clamping pieces 11, one end of each of the two clamping pieces 11 being sleeved on the rod body of the first screw rod 10, one end of a second screw rod 12 being arranged in the other end of the two clamping pieces 11, and a plurality of nuts 13 being sleeved on the first screw rod 10 and the second screw rod 12; once it is necessary to install the cutting saw, the nuts 13 are loosened, the clamping pieces 11 are opened to expand the clamping range, then the handle 17 of the cutting saw is placed in the clamping range, the clamping pieces 11 are adjusted to clamp the handle 17 of the cutting saw, and the nuts 13 are tightened again.

[0041] In the above embodiment, even though the embedded arrangement of the sliding roller 4 and the support of the auxiliary gear 7 make the installation of the sliding plate 5 and the clamping base 8 more stable, the arrangement of the clamping mechanism is likely to cause the center of gravity to deviate to one side of the clamping base 8, so a sliding strip 14 is arranged on the side wheel bottom of the gear strip 2, a lower roller 15 is arranged on one side of the sliding plate 5, and the lower roller 15 is located below the sliding roller 4; the wheel surface of the lower roller 15 is provided with an annular recess, and the sliding strip 14 is embedded in the annular recess of the lower roller 15; the arrangement of the lower roller 15 increases the connection between the gear strip 2 and the sliding plate 5, so that the installation of the sliding plate 5 is more stable. At this time, if the center of gravity deviates to one side of the clamping base 8, it is equivalent to needing to drive the gear strip 2 and the base 1 to deviate, and the mass of the base 1 of the gear strip 2 is large, so the deviation is not established.

[0042] As shown in the figure, Figures 3-4As shown, the clamping piece 16 is movably installed on the top of the sliding plate 5, and the clamping end of the clamping piece 16 is inserted into the auxiliary gear 7, and the clamping piece 16 can effectively prevent the auxiliary gear 7 from rolling downward due to gravity after being positioned at a proper position.

[0043] It should be noted that the angle adjusting device of the gypsum board cutting saw designed by the utility model, when in use, only needs to manually expand the clamping range of the clamping piece 11 by loosening the nut 13, then the handle 17 of the cutting saw is placed into the clamping range, the clamping piece 11 is adjusted to clamp the handle 17 of the cutting saw and the nut 13 is tightened again for fixation, at this time, the sliding plate 5 is manually pushed, the sliding plate 5 drives the clamping base 8 and the clamping piece 11 to move, the sliding plate 5 drives the sliding roller 4 to slide on the slide rail 3, and the auxiliary gear 7 also rolls on the gear strip 2, when reaching a proper angle, the clamping piece 16 is clamped into the pinch of the auxiliary gear 7, so that the auxiliary gear 7 cannot rotate, and then the cutting work can be started.

[0044] Although the embodiments of the utility model have been shown and described, for those skilled in the art, it is understood that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
