[0052] When the auxiliary component 400 is located at the pre-installation position, the base 100 and the handle base 200 are positioned;

[0053] When the auxiliary member 400 is located at the fixed position, the base 100 and the handle base 200 are locked.

[0054] The above is the basic solution of this embodiment.

[0055] Specific reference Figure 1 As shown, a recess is provided on the base 100 to form a mounting groove 101, and the handle seat 200 is in a bowl shape and is embedded in the mounting groove 101. The shape of the handle seat 200 is consistent with the mounting groove 101; the handle 300 is installed in the handle seat 200, and the bent arm on the handle 300 is hinged to the handle seat 200, and is consistent with the structure of the handle 300 in the prior art. The bent arm is provided at the upper end of the handle 300, and the lower end of the handle 300 can be pulled out by hand;

[0056] In addition, in order to facilitate human hand insertion and operation, in this embodiment, the pull groove 301 is set on the lower end surface of the handle 300. At the same time, when the handle 300 is located in the handle groove 201, there is still space for human hand insertion at the bottom of the handle groove 201.

[0057] In this embodiment, the auxiliary component 400 has at least a first guide portion and a second guide portion, wherein a guiding movement is formed between the first guide portion and the base 100 ; and a guiding movement is formed between the second guide portion and the handle seat 200 and the handle seat 200 is locked.

[0058] During assembly, the auxiliary component 400 is first positioned on the back of the base 100 through the first guide portion, and then the handle base 200 to which the handle 300 has been hinged is embedded into the mounting groove 101. The mounting portion on the back of the handle base 200 passes through the base 100 and the auxiliary component 400 on the back of the base 100 is positioned through the second guide portion. The auxiliary component 400 is operated to move it to a fixed position, and the base 100 and the handle base 200 are locked and fixed.

[0059] In order to ensure the installation stability of the auxiliary component 400, the auxiliary component 400 and the base 100 are fixedly connected by screws.

[0060] In this embodiment, the specific implementation of the auxiliary component 400 is as follows: the first guiding portion is a first guiding groove 401, the first guiding groove 401 is arranged between two lift pieces 410, and the auxiliary component 400 is provided with a first avoidance groove 402 to enable the first guiding portion 110 on the base 100 to extend into and be located at the corresponding position of the first guiding groove 401.

[0061] Reference Figure 2 and Figure 5 As shown, the two tilting pieces 410 are tilted relative to the end surface of the auxiliary component 400, a narrow groove is formed between the two tilting pieces 410, and the first avoidance groove 402 is connected with the first guide groove 401. When the first guide part 110 is extended into the first avoidance groove 402, it can slide into the first guide groove 401, so that the auxiliary component 400 and the base 100 are positioned.

[0062] In order to cooperate with the first guide groove 401 , in this embodiment, the first guide portion 110 is a protrusion extending from the back of the base 100 , and the first guide portion 110 is provided with a first pressing portion 111 extending toward at least one side of the tilting piece 410 .

[0063] In this embodiment, the function of the first guide portion 110 is to press the lifter 410 tightly, so that the auxiliary component 400 and the back of the base 100 are in close contact;

[0064] During the pre-installation process, the first guide portion 110 extends into the first avoidance groove 402, and the positions of the first guide portion 110 and the first guide groove 401 are made to correspond, and the auxiliary member 400 is slid to make the first guide portion 110 slide into the first guide groove 401. At this time, the first pressing portion 111 on the side of the first guide portion 110 presses the tilting piece 410 on this side, that is, in this state, the tilting piece 410 is located in the small gap formed by the first pressing portion 111 and the back of the base 100, thereby completing the positioning connection between the auxiliary member 400 and the back of the base 100, referring to Figure 8 and Fig. 9 shown.

[0065] In other embodiments, two first pressing portions 111 may be provided, respectively disposed on both sides of the first guide portion 110 , to press the two lift pieces 410 simultaneously.

[0066] In this embodiment, the second guide groove 403 is used to guide the relative movement between the handle seat 200 and the auxiliary member 400. The specific implementation method is as follows: the second guide groove 403 is a narrow groove, and the starting end of the narrow groove is connected to the second avoidance groove 404. The handle seat 200 is provided with a second guide portion 210 that passes through the base 100 and extends into the second avoidance groove 404, and slides along the second guide groove 403. Figure 2 and Figure 6 shown.

[0067] Preferably, in this embodiment, two of the second guide groove 403 , the second avoidance groove 404 and the second guide portion 210 are provided in cooperation and are symmetrically arranged.

[0068] Reference Figure 2As shown, the second guide groove 403 and the second avoidance groove 404 are connected and arranged, and the second guide portion 210 first extends into the second avoidance groove 404 and corresponds to the guide path of the second guide groove 403. During assembly, the auxiliary component 400 is moved to move the second guide portion 210 relative to the auxiliary component 400. When the second guide portion 210 moves into the second guide groove 403, the fixation of the handle 300 seat 200 on the base 100 is completed.

[0069] In this embodiment, during assembly, the base 100 and the handle base 200 are fixed, and only the auxiliary component 400 is moved, and the auxiliary component 400 completes its pre-installation on the back of the base 100 by moving in the first direction. Figure 5 , and then the installation of the handle seat 200 is completed by moving in the second direction, and the first direction is opposite to the second direction, refer to Figure 8 .

[0070] Therefore, in the setting of the first guide groove 401 and the second guide groove 403, the opening positions of the two guide grooves are opposite. It can also be seen that the relative position of the first guide groove 401 and the first avoidance groove 402 is set in the opposite direction to the relative position of the second guide groove 403 and the second avoidance groove 404.

[0071] At the same time, in order to allow the second guide portion 210 on the handle base 200 to pass through the base 100 , a third avoidance groove 102 is provided on the base 100 .

[0072] To ensure stable installation of the handle base 200 , in this embodiment, the width of the second guide portion 210 is consistent with the width of the second guide groove 403 , and a limiting portion 211 is extended from at least one of the side portions.

[0073] Specific reference Figure 4 As shown, in this embodiment, the purpose of the limiting portion 211 is to limit the base 100 and the auxiliary component 400 in the limiting groove formed between the back of the handle base 200 and the limiting portion 211, so as to prevent the handle base 200 from coming off the base 100 and the auxiliary component 400;

[0074] Therefore, the limiting portion 211 in this embodiment can be set on any one side or multiple sides of the second guide portion 210, so that the cross-section of the second guide portion 210 at the position of the limiting portion 211 is larger than the second guide groove 403, so that the second guide portion 210 cannot be separated from the second guide groove 403.

[0075] In this embodiment, the movable position of the auxiliary component 400 is limited, and the specific implementation is as follows: the auxiliary component 400 is pressed and arranged on the back of the base 100 , and the back of the base 100 is provided with an assembly groove 103 capable of accommodating the auxiliary component 400 .

[0076] The auxiliary member 400 is slidable within the fitting groove 103 .

[0077] Specifically, the groove edge of the assembly groove 103 is extended toward one side of the assembly groove 103 with an auxiliary protrusion 120, a clamping groove 103.1 is formed between the auxiliary protrusion 120 and the groove bottom of the assembly groove 103, and the auxiliary component 400 is provided with an auxiliary part 420 that can be inserted into the clamping groove 103.1.

[0078] Reference Figure 3 and Figure 6 As shown, in this embodiment, the clamping groove 103.1 formed between the auxiliary protrusion 120 and the bottom of the assembly groove 103 is a side groove, the groove width of the side groove is consistent with the height of the auxiliary part 420, and in the pre-installed state, the auxiliary part 420 is located outside the clamping groove 103.1. When the sliding auxiliary component 400 is tightened, the auxiliary part 420 slides into the clamping groove 103.1, so that the clamping groove 103.1 on the base 100 limits the auxiliary component 400. At the same time, the auxiliary component 400 limits the handle 300 seat 200, and the base 100 is clamped between the handle 300 seat 200 and the auxiliary component 400, thereby forming a mutual limit fixation between the three.

[0079] To ensure that the auxiliary part 420 can slide smoothly into the clamping groove 103.1, in this embodiment, an auxiliary groove 103.2 is also provided on the groove wall of the assembly groove 103, and the auxiliary groove 103.2 is formed by an elastic hook 130 arranged on the groove wall of the assembly groove 103, and the auxiliary groove 103.2 is arranged parallel to the clamping groove 103.1.

[0080] When the auxiliary component 400 is pre-installed in the assembly groove 103, interference occurs between the hook portion of the elastic hook 130 and the auxiliary portion 420, and the auxiliary portion 420 presses the elastic hook 130 downward, and the elastic hook 130 deforms and bends outward, so that the auxiliary portion 420 can pass over the hook portion of the elastic hook 130 and enter the auxiliary groove 103.2. At this time, the elastic hook 130 is reset and the auxiliary portion 420 is limited to the auxiliary groove 103.2, so that the auxiliary portion 420 can directly slide from the auxiliary groove 103.2 into the clamping groove 103.1. Figure 5 shown.

[0081] Preferably, the auxiliary component 400 is a mounting plate, and the auxiliary portion 420 is a bent plate disposed on the edge of the mounting plate.

[0082] During assembly, the mounting piece is in close contact with the bottom of the assembly groove 103, and the bending piece is bent outward.

[0083] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
