The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments, such as "inside", "outside", "left", "right" and similar expressions are only for the purpose of explanation and are not intended to limit the present invention.

[0022] Please refer to Figures 1 to 3 , is a schematic diagram of a rubber scraper 100 of the utility model, Figure 4 For scraper 100

[0023] Schematic diagram of various types of scraper blades. The scraper blade 100 includes a handle 20, a locking assembly 30 installed on the handle 20, and a scraper blade 40 with one end inserted into the handle 20 and engaged with the locking assembly 30. The handle 20 is provided with an insertion slot 21 extending along the length direction, a female nail hole 22 extending along the thickness direction, and a screw hole 23. The female nail hole 22 is arranged opposite to the screw hole 23 and is connected to the insertion slot 21. The locking assembly 30 includes a female nail 31 and a compression spring 32 installed in the female nail hole 22, and a screw 33 installed in the screw hole 23. The female nail 31 passes through the compression spring 32 and is connected to the screw 33. A card interface 41 is provided at one end of the scraper blade 40, and the card interface 41 is adapted to be engaged with the screw 33.

[0024] The above-mentioned scraper blade 100, since the handle 20 is provided with an insertion groove 21, a female nail hole 22 and a screw hole 23, the locking assembly 30 includes a female nail 31, a compression spring 32 and a screw 33, and one end of the scraper blade 40 is provided with a card interface 41 that is adapted to be connected with the screw 33, when in use, the handle 20 and the scraper blade 40 can be disassembled or replaced as needed. Because the handle 20 and the scraper blade 40 can be disassembled or replaced as needed, when disassembling, the space occupied can be reduced, which is convenient for carrying and storage. When the original scraper blade 40 is damaged and needs to be replaced or a new size scraper blade needs to be replaced to adapt to a new working scene, the scraper blade 40 can be quickly replaced without scrapping the handle 20, and the use will not cause waste, which is highly practical.

[0025] Furthermore, a support step 24 is provided on the handle 20 , one end of the compression spring 32 abuts against the support step 24 , and the other end of the compression spring 32 abuts against the female nail 31 , so that the compression spring 32 is clamped between the support step 24 and the female nail 31 .

[0026] Furthermore, the screw 33 is provided with a limiting step 34, and the limiting step 34 is adapted to be engaged with the card interface 41. The screw 33 is provided with a conical column 35, and the female nail 31 is provided with a tapered groove (not shown), and the conical column 35 is adapted to the tapered groove. During installation, the compression spring 32 and the female nail 31 are first placed in the female nail hole 22, wherein the compression spring 32 is sleeved on the outer periphery of the female nail 31, and then the screw 33 is inserted from the screw hole 23 and fixedly connected through the interference fit between the conical column 35 and the tapered groove.

[0027] Furthermore, the scraper blade 40 is provided with a guide opening 42 connected to the card interface 41, and the diameter of the guide opening 42 is smaller than the diameter of the card interface 41. When assembling the scraper blade 40, first press the female nail 31 downward to make it move the screw 33 downward and compress the compression spring 32 to store elastic force, then insert the scraper blade 40 from the insertion slot 21, move inward toward the conical column 35 through the guide opening 42 until the card interface 41 is located just above the limit step 34, then release the female nail 31, the screw 33 will rise under the reset elastic force of the compression spring 32, and then the limit step 34 will rise into the card interface 41 to complete the card connection and fixation, and finally the scraper blade 40 is locked on the handle 20. When it is necessary to remove the scraper blade 40, just press the female nail 31 downward to drive the limit step 34 to withdraw from the card interface 41, and then pull the scraper blade 40 out of the insertion slot 21.

[0028] Furthermore, the scraping blade 40 is provided with symmetrically distributed notches 43 . The provision of the notches 43 can save materials and also increase the elasticity of the scraping end of the scraping blade 40 .

[0029] Furthermore, the handle 20 is provided with a plurality of anti-slip strips 25, which are located on the top and bottom surfaces of the handle 20. The anti-slip strips 25 are arranged at equal intervals, so that the anti-slip effect is further improved. Furthermore, the handle 20 is provided with a plurality of convex patterns 26, which are located on both sides of the handle 20, so that the handle 20 is not easy to slip on both sides when in use, and is held firmly when scraping glue.

[0030] Furthermore, the handle 20 is provided with two recessed portions 27 , which are symmetrically located on both sides of the handle 20 . The provision of the recessed portions 27 can improve the comfort of hand holding.

[0031] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
