Abstract
Description
Technical Field
[0001] The utility model relates to the field of razors, in particular to a razor with convenient blade replacement. Background Art
[0002] A razor is a personal care tool used to shave hair on the face or other parts of the body. It can be divided into two categories: manual razors and electric razors according to its design and usage.
[0003] A traditional manual razor usually consists of a blade holder and a blade head. The blade head has multiple sharp blades, and hair is shaved by the blades. However, when the blades of existing razors are worn, most of them directly replace the entire blade head, which is very costly.
[0004] Therefore, in view of the above problems, a razor which is convenient for replacing blades and can only replace blades and effectively save costs has been developed. Summary of the invention
[0005] In order to overcome the disadvantage that most existing razors require direct replacement of the entire blade head after the blade is worn, which is costly, the utility model provides a razor that is easy to replace the blade and can effectively save costs.
[0006] The technical solution is: a razor that is easy to replace blades, including a handle, a docking column, a docking frame, a rotating connection frame, a clamping frame, a fixed threaded column, a fixing nut and a blade. The upper and lower sides of the handle are connected to the docking columns, the docking frame is clamped on the docking column located at the upper part, the rotating connection frame is rotatably connected to the docking frame, a clamping frame is arranged above the rotating connection frame, the lower sides of the left and right parts of the clamping frame are connected to the fixed threaded columns, the fixed threaded columns are slidably connected to the rotating connection frame, the fixed threaded columns are threadedly connected to the fixing nuts, a plurality of blades are clamped on the upper part of the rotating connection frame, the fixing nut is rotated to disengage it from the fixed threaded column, so that the clamping frame no longer clamps and limits the blades, and the blades can be replaced.
[0007] Furthermore, the handle is provided with anti-slip grooves to increase friction.
[0008] Furthermore, a limiting piece is provided on the lower side of the positioning frame to facilitate the positioning of the blade.
[0009] Furthermore, it also includes an elastic part. The lower sides of the left and right parts of the clamping frame are connected to the rotating connecting frame with elastic parts. The elastic parts are all wound around the fixed threaded columns. Under the action of the elastic parts, the clamping frame is driven to move upward, so that the distance between the clamping frame and the rotating connecting frame is increased, and the clamping frame no longer clamps and limits the blade, thereby facilitating the user to replace the blade clamped on the rotating connecting frame.
[0010] Furthermore, the elastic member is a spring.
[0011] Furthermore, it also includes a protective cover. The front and rear parts of the rotating connecting frame are both rotatably connected with the protective cover. The blade is isolated by the protective cover to prevent the blade from accidentally scratching the user when not in use.
[0012] Compared with the prior art, the utility model has the following advantages: 1. The utility model rotates the fixing nut to disengage it from the fixed threaded column, and under the action of the spring, drives the clamping frame to move upward away from the rotating connecting frame, so that the clamping frame no longer clamps and limits the blade. Then, the blade can be replaced, which can achieve the effect of only replacing the blade and effectively saving costs.
[0013] 2. The utility model provides protective covers at the front and rear parts of the rotating connecting frame, so that the blade can be isolated by the protective cover to prevent the blade from accidentally scratching the user when not in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.
[0020] A razor with easy-to-replace blades, such as Figure 1-Figure 4As shown, it includes a handle 1, a docking column 2, a docking frame 3, a rotating connecting frame 4, a clamping frame 5, a fixed threaded column 6, a spring 7, a fixing nut 8, a blade 9 and a protective cover 10. The handle 1 is connected to the docking column 2 on the upper side, the docking frame 3 is clamped on the docking column 2 at the upper part, the rotating connecting frame 4 is rotatably connected to the docking frame 3, and a clamping frame 5 is arranged above the rotating connecting frame 4. The lower sides of the left and right parts of the clamping frame 5 are connected to the fixed threaded column 6, the fixed threaded column 6 is slidably connected to the rotating connecting frame 4, the lower sides of the left and right parts of the clamping frame 5 are connected to the rotating connecting frame 4 with springs 7, the springs 7 are wound on the fixed threaded column 6, the fixed threaded column 6 is threadedly connected to the fixing nut 8, three blades 9 are clamped on the upper part of the rotating connecting frame 4, and the front and rear parts of the rotating connecting frame 4 are rotatably connected to the protective cover 10.
[0021] When the utility model is in use, the user holds the handle 1 to pick up the utility model, then rotates and opens the protective cover 10 on one side, and makes the blade 9 close to the face. The user drives the blade 9 to move and shave the facial hair. During use, the rotating connecting frame 4 can be rotated on the docking frame 3 so that the blade 9 can better fit the user's face. After use, the protective cover 10 is rotated to reset it, so that the blade 9 can be isolated by the protective cover 10 to prevent the blade 9 from accidentally scratching the user when not in use. When one side of the blade 9 is worn, the protective cover 10 on the other side can be rotated to open. , use the other side of the blade 9, when the front and rear sides of the blade 9 are worn, the fixing nut 8 can be rotated to disengage it from the fixing threaded column 6, at this time, the clamping frame 5 is driven to move upward under the action of the spring 7, so that the distance between the clamping frame 5 and the rotating connecting frame 4 is increased, and the clamping frame 5 no longer clamps and limits the blade 9, and then the user can replace the blade 9 clamped on the rotating connecting frame 4. After the replacement is completed, the fixing nut 8 is rotated again, so that the clamping frame 5 is close to the rotating connecting frame 4 again, and the blade 9 is clamped and limited by the clamping frame 5, and the spring 7 is compressed.
[0022] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
