Description

Technical Field

[0001] This utility model pertains to aquarium cleaning tools, specifically an algae scraper. Background Technology

[0002] Algae and limescale inside the aquarium need to be cleaned regularly with an algae scraper. Currently, there are two common blade fixing methods for such products on the market. The first method uses screws to fix the blade, generally including the blade body, a clamping plate, and two fixing screws. The two fixing screws also serve to position the blade. During installation, the two screws need to pass through the two positioning holes of the clamping plate, then through the positioning hole of the blade, and then be screwed into the screw hole of the blade body. Fixing blades with screws is the most common, and theoretically the most common, method of fixing objects. However, in practice, due to the need to control the thickness of the blade body, relatively thin screws are generally used to achieve a good ratio between the screw diameter and depth, which increases the difficulty of installation. Most importantly, the two screws serve to position the blade. Before tightening the screws, the clamping plate and blade are generally not positioned, and it is necessary to keep the clamping plate, blade, and blade body in the correct position at the same time, without any slippage. Otherwise, the screws will not be able to be screwed into the screw holes, making blade replacement more complicated, and improper operation can easily result in finger cuts.

[0003] Another method involves slightly deforming the blade body to clamp the blade. Typically, the blade body has a pre-designed space for blade installation, with the clamping end being less than the blade thickness. During installation, the blade is inserted into the blade body from one side to secure it. This method requires precise control of the blade's manufacturing tolerances; large tolerances can result in insufficient clamping or loosening. Furthermore, installation requires holding the blade and inserting it into the blade body, and the blades are usually razor blades or algae scraper blades, which are extremely sharp and can easily cut fingers. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems and provide a scraper algae.

[0005] To achieve the above objectives, this utility model provides a scraper algae, including a blade head, a handle connected to the blade head, a blade mounted on the blade head, and a fixing piece located on the blade and cooperating with the blade head.

[0006] Furthermore, the cutter head is provided with a positioning post, and the fixing plate is provided with a positioning hole that cooperates with the positioning post; The positioning post has a groove, and the positioning hole has a first elastic positioning buckle and a second elastic positioning slot that are arranged opposite to each other and cooperate with the groove.

[0007] Furthermore, the fixing piece is also provided with a finger groove.

[0008] Furthermore, the positioning hole has an arc-shaped groove on its edge.

[0009] Furthermore, it also includes an extension shank that is threaded to the tool holder, with a hanging ring at the end of the extension shank away from the tool holder.

[0010] Furthermore, it also includes a protective case.

[0011] The beneficial effects of this utility model are as follows: This utility model's algae scraper, through its structure of a positioning post, groove, first elastic buckle, second elastic buckle, and finger groove, makes the installation and replacement of the blade simple and convenient, and also provides good safety, preventing blade scratches.

[0013] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0015] Combination Figures 1-6 As shown, this utility model provides an algae scraper, including a blade head 1, a handle 2 connected to the blade head 1, and an extension handle 5 threadedly connected to the handle 2. The end of the extension handle 5 away from the handle 2 is provided with a hanging ring 51.

[0016] The algae scraper of this utility model includes a blade 3 mounted on a blade head 1, and a fixing piece 4 located above the blade 3 and cooperating with the blade head 1. In this embodiment, the blade head 1 is provided with a positioning 11, and the fixing piece 4 is provided with a positioning hole 41 that cooperates with the positioning post 11. The positioning post 11 is provided with a groove 111, the top of the groove is inclined to a certain extent, and the two sides of the groove are rounded chamfered. The positioning hole 41 has a first elastic positioning buckle 411 and a second elastic positioning slot 412 that are oppositely arranged and cooperate with the groove 111. The fixing piece 4 is also provided with a finger groove 42. The edge of the positioning hole 41 is provided with an arc-shaped groove 413.

[0017] The algae scraper of this utility model, with the above-described structural design, is installed and used as follows: During installation, align the positioning hole of the blade 3 with the positioning post 11 of the cutter head 1, and place the blade 3 on the cutter head 1. Then align the center position of the positioning hole 41 of the fixing plate 4 with the positioning post 11 on the cutter head 1, and place it on the cutter head 1. The installation state at this time is as follows. Figure 4 As shown. Then, the fixing piece 4 can be pushed to the bottom of the blade head 1 through the finger groove 42, exposing the blade 3. The blade is then pressed and fixed by the first elastic buckle 411 engaging with the groove 111 of the positioning post 11. After use, the fixing piece 4 is pushed outward through the finger groove 42 so that the outer side of the fixing piece 4 extends beyond the blade 3. The blade is then pressed and fixed by the second elastic buckle 412 engaging with the groove 111 of the positioning post 11. At this time, the blade is in the retracted state, avoiding the risk of scratching during installation.

[0018] According to the concept of this utility model, it also includes a protective sleeve 6, which can be installed on the cutter head 1 to provide overall protection when not in use.

[0019] The algae scraper of this utility model, through the above-mentioned structural design, makes the installation and replacement of the blade simple and convenient, and has good safety, preventing blade scratches.

[0020] The above description is merely one embodiment of this utility model and is not intended to limit the utility model.
