[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-3As shown, a multifunctional shovel blade includes a shovel head 3, a hollow blade rod 4 and a screwdriver 6. The screwdriver 6 is inserted into one end of the hollow blade rod 4. The screwdriver 6 is detachably connected to the hollow blade rod 4. The shovel head 3 is fixedly connected to the other end of the hollow blade rod 4. The shovel head 3 includes two clamping plates 7. The two clamping plates 7 are fastened by screws 2 for clamping and fixing the blade 1. The groove shape at the end of the screw 2 is adapted to the blade head of the screwdriver 6.

[0030] When the blade 1 needs to be replaced, the screwdriver 6 is removed, the screw 2 is unscrewed by the screwdriver 6, and the fastening of the two clamping plates 7 is released. Then, the blade 1 can be pulled out from between the two clamping plates 7, and a new blade 1 is placed between the two clamping plates 7. The screw 2 is tightened and the blade 1 is clamped and fixed by the two clamping plates 7. After the replacement is completed, the screwdriver 6 is inserted into the hollow blade rod 4 for the next use. By providing a detachable screwdriver 6 at the end of the hollow blade rod 4, the screwdriver 6 can be easily taken out when replacing the blade 1, and there is no need to prepare a separate screwdriver 6, thereby making the replacement of the blade 1 more convenient.

[0031] In some embodiments, both the screwdriver 6 and the shovel head 3 are provided with external threads 13, and both ends of the hollow shank 4 are provided with internal threads 12. The hollow shank 4 and the shovel head 3 are both threadedly connected to the screwdriver 6. By using threads to securely connect the shovel head 3 to the hollow shank 4, the shovel head 3 can be easily removed and replaced. At the same time, the screwdriver 6 and the hollow shank 4 are threadedly connected to facilitate access to the screwdriver 6.

[0032] See also Figure 4 As shown, in some embodiments, the corresponding positions of the screwdriver 6 and the hollow shank 4 are fixedly connected with magnetic blocks 14, and the screwdriver 6 and the hollow shank 4 are fixed by magnetic attraction. The use of magnetic attraction fixation makes it more convenient to take the screwdriver 6.

[0033] In order to facilitate the insertion of the blade 1 , a slot 8 is provided between the two clamping plates 7 , and the width of the slot 8 is slightly larger than the thickness of the blade 1 .

[0034] Specifically, the screw 2 passes through one of the clamping plates 7 and is threadedly connected to the other clamping plate 7. When the blade 1 is clamped and fixed by the two clamping plates 7, as the screw 2 is tightened, the screw 2 pulls the two clamping plates 7 to generate elastic deformation to clamp and fix the blade 1.

[0035] To facilitate control of the installation position of blade 1, a limiting slot 10 is provided at the position corresponding to screw 2. When installing blade 1, screw 2 is pre-installed on clamping plate 7 using screwdriver 6, blade 1 is inserted into slot 8, and blade 1 is limited in position by the cooperation of screw 2 and limiting slot 10. Then screw 2 is tightened, and blade 1 is clamped and fixed by two clamping plates 7.

[0036] In order to facilitate gripping, a rubber handle 5 is fixedly connected to the outer side of one end of the hollow shank 4 away from the shovel head 3 .

[0037] In some embodiments, a metal block 9 is fixedly connected to the end of the handle of the screwdriver 6. The metal block 9 is provided to prevent the tail of the scraper from being worn when it is struck.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
