[0027] like Figures 1 to 3As shown, a specific embodiment of the utility model discloses a double-handled trowel for plastering, including a scraper 100, a support bar 110 is welded and fixed on the top surface of the scraper 100, and a slide groove 120 extending along the length direction is provided on the support bar 110; a plurality of card grooves 130 are provided at the bottom of the slide groove 120, and the card grooves extend along the width direction of the support bar, and the plurality of card grooves are evenly spaced along the length direction of the support bar; two handle structures 200 are installed at the slide groove 120, and the handle structure slides along the slide groove; a locking assembly 300 is provided on the handle structure 200, and the handle structure 200 is snap-fitted with the card groove 130 through the locking assembly 300 to form a lock.

[0028] The above-mentioned double-handled trowel for plastering has a novel structure. The handle structure is locked by a locking assembly and maintained in a corresponding position. Construction workers can adjust the position of the handle according to needs to provide comfortable operating conditions and improve work efficiency and quality.

[0029] In addition, a card slot is provided at the bottom of the slide slot, and the locking assembly and the card slot are engaged with each other to achieve locking, which can block the lock in both the width and length directions, thereby improving the locking stability and effectively preventing loosening or displacement.

[0030] Furthermore, if Figure 3 , Figure 4 The handle structure 200 includes a slide 210, and a handle 220 is fixed on the top surface of the slide 210; the slide is slidably clamped in the slide groove; the slide and the handle are provided with a receiving space along the axial direction, and the locking assembly is installed in the receiving space, and the clamping part of the locking assembly can pass through the bottom surface of the slide and extend out of the bottom, and the adjustment part of the locking assembly passes through the top of the handle and extends out of the outside; the slide is slidably clamped in the slide groove, and only moves along the length direction, and will not detach from the notch of the slide groove. It is locked with the locking assembly, which effectively ensures the overall connection strength and prevents loosening or movement during use.

[0031] Furthermore, if Figures 2 to 6As shown, the accommodating space includes a guide hole 230 and a sink 240 which are interconnected. The sink 240 is a rectangular structure. The sink 240 is arranged at the bottom of the slide 210. The guide hole 230 is located at the center of the bottom of the sink 240. The guide hole 230 passes through the top of the handle 220 along the axial direction of the handle. A limiting ring 250 is fixedly provided on the inner wall of the top of the guide hole 230. The locking assembly 300 includes a guide rod 310. A clamping block 320 is fixedly provided at the bottom of the guide rod 310. A clamping strip 330 is fixedly provided on the bottom surface of the clamping block 320. The shape of the clamping strip 330 matches the shape of the clamping slot 130. A slider 350 is installed on the top of the guide rod 310. 40; the guide rod 310 is slidably arranged at the guide hole 230, the block 320 slides along the inner wall of the recessed groove 240, and the pull head 340 passes through the limiting ring 250 and extends to the outside; a spring 350 is arranged between the guide rod 310 and the limiting ring 250, which provides the guide rod with an elastic force to push downward, so that the card strip remains stuck in the card slot; when the pull head is pulled upward, the card strip can be separated from the card slot and the lock is released; the overall assembly structure is adopted, which can facilitate the processing and production of various structural components, the assembly method is simple, and can provide an effective matching effect, and the spring is used to maintain the required card connection and locking action, and subsequent adjustments can overcome the elastic force of the spring, which is easy to use and operate.

[0032] Furthermore, the depth of the sink is greater than the thickness of the card block and the card strip and is 2mm-5mm. When the card strip is pulled to the point where the movement is limited, the card strip is completely separated from the card slot to achieve the unlocking action. Moreover, this limitation can also prevent excessive extrusion and deformation of the spring, prevent damage to the spring, extend its service life, and maintain the necessary subsequent pushing and locking force.

[0033] Furthermore, if Figure 7 As shown, the pull head 340 includes a support column 341, the diameter of the support column 341 is adapted to the inner diameter of the limit ring 250; a ball head 342 is fixedly provided at the top of the support column 341, and the diameter of the ball head 342 is larger than the diameter of the support column 341; Figure 6 As shown, a threaded column 343 is fixedly provided at the bottom end of the support column 341, and the diameter of the threaded column 343 is smaller than the diameter of the support column 341; a threaded hole 311 is provided on the top surface of the guide rod 310, and the support column slides through a limiting ring, and the threaded column 343 is threadedly connected at the threaded hole 311; the spring 350 is located inside the guide hole and is sleeved on the outside of the support column 341; the outer ring diameter of the spring is adapted to the inner diameter of the guide hole; the pull head is a detachable structure. During installation, the spring is placed in the guide hole, and then the guide rod is inserted into the guide hole, and the block is pushed against the bottom of the groove, and then the support column is inserted into the limiting ring, and the threaded column is connected to the threaded hole, the pull head is fixed, and the assembly is completed; the overall assembly is simple, convenient for disassembly and assembly, and also convenient for subsequent disassembly and replacement of parts.

[0034] Furthermore, a plurality of card strips 330 are fixedly provided on the bottom surface of the card block 320, and the spacing between the card strips 330 is adapted to the spacing between the card slots 130; the locking effect is further enhanced by the card strips being engaged with the card slots, effectively preventing loosening and displacement.

[0035] Furthermore, L-shaped limit plates 260 are fixedly provided on both sides of the bottom of the handle 220. One side of the inner wall of the limit plate 260 slides against the outer wall of the support bar 110, which can further increase the coordination with the support bar, enhance the supporting strength, prevent structural breakage or damage, and extend the service life.

[0036] Furthermore, the slide seat, the handle and the limit plate are an integrated structure, which can ensure the connection strength and structural strength of the handle structure itself, prevent easy breakage and damage, and provide effective support in subsequent use;

[0037] Furthermore, a groove is provided on the side wall of the handle, and the groove forms a closed loop structure around the axis of the handle, serving as a gripping portion, which has an anti-slip effect and is convenient for gripping and use.

[0038] The present invention is described by preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
