DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying Figures 1-4 The application will be further described in detail.

[0021] The application embodiment discloses a shovel for waterproof engineering. Referring to Figures 1-4The utility model provides a spade for waterproof engineering, including extension rod 1, hold pole 4 and spade 7, the bottom end fixedly connected with mounting seat 5 of hold pole 4, the lower surface of mounting seat 5 is seted up with movable slot 10, the inside of movable slot 10 is provided with mounting plate 8, one side of mounting plate 8 is fixedly connected with spade 7, the lateral wall of mounting seat 5 is installed with two fixed bolts 6 in screw thread, the lateral wall of mounting plate 8 is seted up with two thread holes 11 with fixed bolt 6 screw thread cooperation, the top of hold pole 4 is seted up with the accommodation groove 19, the inside of accommodation groove 19 is provided with the screw rod 16 with fixed bolt 6 cooperation use, the bottom end of extension rod 1 is seted up with the insertion slot 12, the top of hold pole 4 is located in insertion slot 12, the inside wall of insertion slot 12 is seted up with inner thread 13, the lateral wall on the top of hold pole 4 is seted up with outer thread 14 with inner thread 13 cooperation use, the bottom end of screw rod 16 is fixedly connected with first magnetic sheet 17, the bottom wall of accommodation groove 19 is fixedly connected with second magnetic sheet 18 with first magnetic sheet 17 magnetic attraction, the one side of mounting seat 5 is seted up with two round grooves 9, and fixed bolt 6 is located in the inside of round groove 9, and the lateral wall on the top of extension rod 1 is provided with rubber sleeve 2, and the lateral wall of hold pole 4 is evenly provided with a plurality of rubber protrusions 3, and the top of screw rod 16 is fixedly connected with knob 15.

[0022] The implementation principle of the shovel for waterproof engineering is as follows: in use, according to the actual needs of the construction scene, if it is necessary to adjust the length of the shovel 7, the insertion slot 12 at the bottom end of the extension rod 1 is aligned with the top end of the handle 4, and the top end of the handle 4 is inserted into the insertion slot 12, because the inner wall of the insertion slot 12 is provided with an internal thread 13, and the side wall of the top end of the handle 4 is provided with an external thread 14 matched with the internal thread 13, the extension rod 1 is rotated to be tightly fixed with the handle 4 through the threaded connection, so that the overall length of the shovel 7 is extended, and it is convenient to perform construction operation in a narrow space or at a high place. When it is necessary to replace the shovel 7, the twisting rod 16 fixed with the first magnetic sheet 17 at the bottom end is taken out from the storage groove 19 at the top end of the handle 4, the second magnetic sheet 18 magnetically attracted to the first magnetic sheet 17 is fixed to the bottom wall of the storage groove 19, the twisting rod 16 is stably stored in the storage groove 19 through the magnetic attraction, and the twisting rod 16 can be taken out by being gently pulled out in use. The knob 15 at the top end of the twisting rod 16 is held, the twisting rod 16 is aligned with the fixing bolt 6 in the circular groove 9 on the side wall of the mounting seat 5, the fixing bolt 6 is rotated by the twisting rod 16, and the fixing bolt 6 is rotated out of the threaded hole 11 in the side wall of the mounting plate 8. The fixing bolt 6 is located in the circular groove 9, which plays a role in protecting the fixing bolt 6 and facilitating the operation of the twisting rod 16. After the fixing bolt 6 is rotated out, the mounting plate 8 and the shovel 7 can be taken out from the movable groove 10 in the lower surface of the mounting seat 5, then a new shovel 7 and a mounting plate 8 are replaced, the fixing bolt 6 is rotated into the threaded hole 11, and the replacement of the shovel 7 is completed. In the actual construction process, the construction personnel hold the handle 4 to work, and the rubber protrusions 3 uniformly arranged on the side wall of the handle 4 and the rubber sleeve 2 at the top end of the extension rod 1 can increase the friction between the hands and the shovel 7 and improve the stability of holding to prevent the shovel 7 from slipping off in the construction process. When the construction personnel use the shovel 7 to shovel off the floating slurry, oil stains, sundries or old waterproof coating on the surface of the waterproof engineering base layer, the angle and force of the handle 4 are controlled, and the shovel edge of the shovel 7 is used for work. In this process, the length of the shovel 7 can be flexibly adjusted according to the actual construction needs through the threaded connection design of the extension rod 1 and the handle 4, the convenience and efficiency of construction are improved, the replacement process of the shovel 7 is simple and fast through the setting of the fixing bolt 6 and the threaded hole 11 on the mounting seat 5 and the mounting plate 8 and the operation of the twisting rod 16 stored in the handle 4, the construction cost is reduced, the twisting rod 16 is stored in the storage groove 19 of the handle 4 through the magnetic attraction, the twisting rod 16 is avoided from being lost, and the twisting rod 16 is conveniently taken out at any time, so that the construction personnel do not need to additionally find tools when replacing the shovel 7, and the convenience of construction is further improved.
