[0024] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] like Figure 1 As shown in the figure, a device for quickly removing the cone head of a three-stage tensioning waterstop screw comprises an expansion head 1, and a hexagonal screw bit 2 is installed on the upper end of the expansion head 1; the expansion head 1 comprises a mounting shell 11, and a tensioning and extruding column 12 is sleeved in the mounting shell 11, and a plurality of clamping columns 13 are squeezed on the outer side wall of the tensioning and extruding column 12, and the clamping column 13 is assembled on the mounting shell 11.

[0027] In a specific implementation, the mounting shell 11 includes a shell 111, a counterweight shell 112 is integrally formed at the upper end of the shell 111, a limiting spring ring 113 is clamped at the upper end of the inner wall of the counterweight shell 112, a plurality of chamfered grooves 114 are penetrated through the outer wall of the shell 111, the chamfered grooves 114 are sleeved together with the clamping column 13, and an insertion chamfer 115 is integrally formed on the lower side of the shell 111.

[0028] The weight shell 112 is used for installing the bearing 122 and for increasing the overall weight of the mounting shell 11 to prevent the compression column 12 from being easily driven to rotate when the compression column 13 is not squeezed out.

[0029] Specifically, the outer width of the chamfered groove 114 is smaller than the diameter of the pressing column 13. In order to prevent the pressing column 13 from falling out of the chamfered groove 114, it is necessary to ensure that the outer width of the chamfered groove 114 is smaller than the diameter of the pressing column 13.

[0030] In a specific implementation, the tensioning and extrusion column 12 includes an extrusion column 121 and a bearing 122. The extrusion column 121 is inserted into the interior of the shell 111. The outer wall of the extrusion column 121 is integrally formed with a plurality of socket grooves 123. The plurality of socket grooves 123 are respectively socketed with the plurality of clamping columns 13. The upper end of the outer wall of the extrusion column 121 is fixedly connected to the inner ring of the bearing 122. The bearing 122 is socketed in the counterweight shell 112 and is limited by the limiting spring ring 113. A hexagonal socket 124 is provided at the upper end of the extrusion column 121. A magnet block 125 is fixedly connected to the bottom surface of the hexagonal socket 124.

[0031] Specifically, the hexagonal screwdriver bit 2 includes a screwdriver bit body 21 , a hexagonal plug-in column 22 is integrally formed at the lower end of the screwdriver bit body 21 , the hexagonal plug-in column 22 is plugged into the hexagonal plug hole 124 , and the hexagonal plug-in column 22 is adsorbed together with the magnet block 125 .

[0032] Working principle: When the utility model is in use, the hexagonal prism bit 2 is installed on the hand-held electric drill. Since there is no hexagonal hole at the large diameter end of the cone head of the three-stage pull-to-stop water-stop screw, when it needs to be disassembled, its shell 111 can be directly inserted into the center hole of the cone head of the three-stage pull-to-stop water-stop screw. At this time, the hand-held electric drill is started, and the hand-held electric drill will drive the tensioning and extruding column 12 to rotate, and the tensioning and extruding column 12 is rotatably installed together with the mounting shell 11 through the bearing 122, so that when the tensioning and extruding column 12 rotates rapidly, a speed difference will be generated between the mounting shell 11, so that the extruding column 121 will squeeze out the compression column 13 in the shell 111 and squeeze it on the three-stage pull-to-stop water-stop screw. On the inner wall of the center hole of the rod cone head, a limit will be generated between the extrusion column 121 and the clamping column 13, which will drive the shell 111 to rotate, and the shell 111 will drive the clamping column 13 to rotate, so that the three-stage pull-to-pull water-stop screw cone head can be removed. When there is a hexagonal hole at the large diameter end of the three-stage pull-to-pull water-stop screw cone head, the expansion head 1 can be directly removed, and the hexagonal plug-in column 22 can be inserted into the hexagonal hole at the large diameter end of the three-stage pull-to-pull water-stop screw cone head, and it can be removed with the cooperation of a hand electric drill, so that the utility model realizes the function of convenient disassembly of the three-stage pull-to-pull water-stop screw cone head, and can meet the disassembly and use of different three-stage pull-to-pull water-stop screw cone heads.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
