[0002] A shovel is a hand tool composed of a wide shovel bucket or a shovel body slightly concave in the middle with a handle installed, used for excavating or throwing materials. The existing shovels have only one function and are too simple in function. Therefore, people usually need to prepare various tools such as iron shovels and hoes, and they also cannot meet various needs in the wild. Designing a new type of multifunctional shovel blade to improve the practicality of the overall multifunctional shovel is particularly important. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multifunctional shovel blade that can be used in different occasions.

[0031] The present utility model will be further described below in conjunction with the accompanying drawings through specific embodiments, but it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present invention.
[0032] Embodiment
[0033] A multifunctional shovel blade includes a connecting block 4, which is made of a material with high strength, bendability, and ease of welding, preferably cold-rolled steel plate. As Figure 1 and Figure 7 shown, serrations 3 are provided on the left and right sides of the connecting block 4. A plurality of connecting block fixing holes 12 are horizontally and equidistantly opened in the lower half of the connecting block 4, and the connecting block fixing holes 12 are symmetrically distributed left and right. The upper end of the connecting block 4 is bent forward by 90 degrees to form a baffle 5. The baffle 5 can also be set at different bending angles according to the actual use environment, and an isosceles triangle-shaped notch is opened at the vertical center of the connecting block 4 as an inner triangular connecting groove 10.
[0034] The distance between the upper and lower ends of the connecting block 4 is 12 cm, and it can also be processed into 10 cm, 11 cm, 13 cm, 14 cm or other suitable distances.
[0035] As Figure 3 、 Figure 2 and Figure 7 shown, the pipe handle connector 7 is a circular sleeve structure as a whole. The lower end is stamped to form an outer triangular embedded head 6 with an isosceles triangle structure. The specific dimensions need to be consistent with the inner triangular connecting groove 10, so that the outer triangular embedded head 6 and the inner triangular connecting groove 10 cooperate with each other, and the outer triangular embedded head 6 and the inner triangular connecting groove 10 are fixed by double-sided welding. The isosceles triangle-shaped inner triangular connecting groove 10 increases the welding area, improves the welding strength, and increases the service life. Two pipe handle fixing holes 11 are vertically spaced on the axis of the pipe wall of the pipe handle connector 7. The front and rear hole center lines of the pipe handle fixing holes 11 on the front and rear walls coincide, and a dovetail fixing screw 8 is inserted. A telescopic handle is fixed in the pipe handle connector 7 through the dovetail fixing screw 8, and the screw rod of the dovetail fixing screw 8 passes through the pipe handle fixing holes 11 with coincident front and rear hole center lines.
[0036] It also includes a blade 1, which is made of a metal material with high strength, strong toughness, not easy to bend and wear, preferably high-carbon manganese steel.
[0037] The distance between the upper and lower ends of the blade 1 is 10 cm, and it can also be processed into 8 cm, 9 cm, 11 cm, 12 cm or other suitable distances.
[0038] As Figure 1 and Figure 7As shown, the blade 1 is an isosceles trapezoid structure. The long side of the blade 1 is edge-ground to ensure the sharpness during cutting and can be used to shovel off foreign objects on the surface of an object. A number of blade fixing holes 14 are symmetrically arranged at equal intervals up and down on the short side, preferably 5. Place the short side end of the blade 1 on the front side of the lower end of the connecting block 4. The blade fixing holes 14 and the connecting block fixing holes 12 are aligned. A reinforcing rib plate 2 is placed on the front side of the blade 1 at the blade fixing holes 14. The reinforcing rib plate 2 is provided with reinforcing rib plate fixing holes 13 at positions corresponding to the blade fixing holes 14. The reinforcing rib plate fixing holes 13 and the blade fixing holes 14 are aligned. Prepare 5 fixing rivets 9. The fixing rivets 9 pass through the reinforcing rib plate fixing holes 13, the blade fixing holes 14 and the connecting block fixing holes 12 to rivet and fix the three of the reinforcing rib plate fixing holes 13, the blade fixing holes 14 and the connecting block fixing holes 12. The reinforcing rib plate 2 can prevent the fixing rivets 9 from directly contacting the blade 1, making the blade 1 in a sandwich, with more uniform stress and better protection for the blade 1. During later use, the anti-wear effect between the holes is enhanced to increase the service life.
[0039] The blade 1 with an isosceles trapezoid structure increases the width of the lower end edge. At the same time, the upper end of the blade 1 is narrower than the lower end, with a lighter weight, reducing the pressure on the user during long-term use.
[0040] The fixing rivets 9 are evenly spaced left and right and are symmetrically arranged left and right along the vertical center line of the connecting block 4. The symmetrically arranged fixing rivets 9 ensure the stability during use, evenly disperse the stress, and make it easier to use.
[0041] As Figure 5 、 Figure 6 and Figure 7 shown, the saw teeth 3 can be separately opened at the left and right ends of the connecting block 4 or the blade 1, or the saw teeth 3 can be opened at the left and right ends of both the blade 1 and the connecting block 4, for sawing small branches and hemp ropes that are not easy to break. The specific opening position is determined according to the use requirements, but they all need to be symmetrically opened to ensure the overall balance during use.
[0042] Before use, as Figure 7 shown, first take out the dovetail fixing screw 8, then thread the telescopic handle or other similar handle from the upper end of the pipe handle connector 7 downward, and then thread the dovetail fixing screw 8 to fix between the pipe handle connector 7 and the handle. The two dovetail fixing screws 8 are for ensuring the stability during use, and at the same time, the dovetail fixing screws 8 also enable the user to perform tool-free disassembly and assembly.
[0043] When using this design for ordinary cement roads or courtyards, the blade 1 can shovel off silt and weeds, and the saw teeth 3 can cut off small branches and weed roots on both sides of the road.
[0044] When building or renovating a house, the blade 1 can remove the excess cement ash layer on the ground and walls.
[0045] When cultivating the field, the serrated edge 3 can cut flexible items such as plastic mulch and drawstrings.
[0046] When used in a factory, the blade 1 made of high-carbon manganese steel can cut ordinary iron wires with a diameter of 1 to 3 millimeters and remove excess grease and other debris on the surface of machinery or metal products.
[0047] When removing snow, the blade 1 can clear the accumulated snow and ice on the road and the ice slag hanging on the buildings.
[0048] When raising livestock, the blade 1 can remove the residual feces and other debris in the breeding base.
[0049] From the above examples, it can be seen that this design scheme is applicable to various environments and tasks, taking into account versatility and portability, enabling users to use it in different situations without having to carry multiple tools. The baffle 5 can prevent the items being shoveled from splashing everywhere when the blade 1 shovels silt, weeds, snow and ice, etc., thus facilitating workers to collect and clean the items being shoveled, thereby improving work efficiency, because it reduces the subsequent work that needs to be cleaned after the shoveling operation, making the shoveling cleaner and neater.
