[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1-5 As shown, this embodiment of a quick-connect structure for a depilatory razor head and handle includes a razor head seat 4, a handle 1 on one side of the back of the razor head seat 4, and a connecting component 5 installed between the handle 1 and the razor head seat 4. The connecting component 5 includes a locking block 501, a connecting frame 502, and a connecting plate 503. The connecting plate 503 is located in the middle of the back of the razor head seat 4. The locking block 501 is connected to the hollow structure in the middle of the connecting plate 503, and the locking block 501 protrudes from one side wall of the connecting plate 503. The connecting frame 502 is installed at the top of the handle 1. The part of the connecting frame 502 that mates with the locking block 501 has a locking hole. After the built-in slot on the 2 is inserted into the locking block 501 on the connecting plate 503, the cutter head rear seat 4 and the handle 1 can be quickly connected. A cutter head front seat 2 is set on one side of the cutter head rear seat 4. A floating component 6 is installed between the cutter head rear seat 4 and the cutter head front seat 2. The floating component 6 includes an elastic sheet 601, a linkage plate 602 and a blade mounting plate 603. With the integrated assembly structure of the elastic sheet 601, the linkage plate 602 and the blade mounting plate 603, the button of the original cutter head part and the elastic component are integrated into one, making the assembly process of the cutter head part more efficient and further improving the connection efficiency between the cutter head and the handle.

[0026] like Figures 1-5 As shown, in this embodiment, the connecting plate 503 is bonded to the cutter head seat 4, the locking block 501 is connected to the connecting frame 502 by a snap-fit ​​method, and the connecting frame 502 is bonded to the housing of the handle 1, which can ensure the stable installation of the connecting frame 502 and the locking block 501.

[0027] like Figures 1-5 As shown, in this embodiment, the linkage plate 602 is installed between the cutter head rear seat 4 and the cutter head front seat 2. The blade mounting plate 603 is installed on the side wall of the linkage plate 602 facing the cutter head front seat 2. The elastic sheet 601 is installed on the side wall of the linkage plate 602 facing the cutter head rear seat 4. The cutter head rear seat 4 is mainly used to provide an installation base for the floating component 6. The linkage plate 602 and the blade mounting plate 603 are connected by a snap-fit ​​method. The blade mounting plate 603 has a shaving blade. With the help of the blade on the blade mounting plate 603, the hair on the user's body can be easily shaved. There are four elastic sheets 601. 01 is bonded to the linkage plate 602. The elastic sheet 601 and the linkage plate 602 are an integral structure and are arc-shaped. When the front seat 2 of the cutter head is subjected to external force, the elastic sheet 601 can realize the sliding of the blade mounting plate 603 and the linkage plate 602 into the rear seat 4 of the cutter head. After the linkage plate 602 slides, the elastic sheet 601 will be compressed. After the external force is removed, the elastic sheet 601 will return to its original shape, thereby realizing the floating function of the cutter head. When shaving, the elasticity of the elastic sheet 601 can be used to make the blade float conveniently with the blade mounting plate 603, so as to ensure convenient shaving of hair on the user's body.

[0028] like Figures 1-5 As shown in this embodiment, a protective cover plate 3 is also installed on the outside of the front seat 2 of the blade head. The protective cover plate 3 is inserted into the front seat 2 of the blade head. The protective cover plate 3 can protect the front seat 2 of the blade head when the depilator is not in use. The connection part between the front seat 2 of the blade head and the rear seat 4 of the blade head is also equipped with a sealing ring. The front seat 2 of the blade head and the rear seat 4 of the blade head are connected by a snap-fit ​​method, which can ensure a reliable connection between the rear seat 4 of the blade head and the front seat 2 of the blade head.

[0029] The specific implementation process of this embodiment is as follows: In use, first install the blade mounting plate 603 on the linkage plate 602, and then install the linkage plate 602 on the blade head rear seat 4. Then connect the blade head rear seat 4 and the blade head front seat 2 in a snap-fit ​​manner, and snap the locking block 501 on the connecting plate 503 into the locking hole on the connecting frame 502. This allows for the quick assembly of the handle 1 and the blade head rear seat 4, ensuring that the depilator can be put into use quickly. During use, the design of the connecting component 5 allows the blade head rear seat 4 to be quickly connected to the handle 1 by direct insertion, eliminating the tedious twisting operation and shortening the connection time between the blade head rear seat 4 and the handle 1. At the same time, the connection between the blade head rear seat 4 and the blade head front seat 2 is achieved by using the elastic plate 601, the linkage plate 602, and the blade mounting plate 603, realizing the integrated assembly of the original button and elastic component on the blade head rear seat 4, making the connection between the blade head rear seat 4 and the handle 1 more efficient and with higher connection efficiency.

[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
