[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1-3 , which is the first embodiment of the present utility model, and provides a fixing mechanism, including a mounting block 100, a top of which is provided with an insertion slot 101, a side of which is provided with a telescopic hole 102, a cavity 103 inside which is provided, and a handle 200 is provided inside the insertion slot 101; a locking component 300, which includes a locking rod 301 slidably connected to the inside of the telescopic hole 102, a locking assembly 302 provided inside the cavity 103 and a first return spring 303, and the insertion slot 101, the telescopic hole 102 and the cavity 103 are mutually connected; when in use, by inserting the handle 200 into the insertion slot When the handle 200 is locked, the locking rod 301 is pushed out of the telescopic hole 102 to complete the unlocking. When the handle 200 is locked, the locking rod 301 is pushed out of the telescopic hole 102 to complete the unlocking. When the handle 200 is locked, the locking rod 301 is pushed out of the telescopic hole 102 to complete the unlocking.

[0038] Furthermore, the locking assembly 302 includes a tilting block 302a, a base plate 302b and a first connecting plate 302c, the tilting block 302a is connected to the first connecting plate 302c through the base plate 302b, the tilting block 302a, the base plate 302b and the first connecting plate 302c are all slidably connected to the bottom of the inner cavity of the cavity 103, one end of the locking rod 301 is connected to the first connecting plate 302c, and the two ends of the first return spring 303 are respectively connected to the tilting block 302a and the inner wall of the cavity 103; when the handle 200 contacts and squeezes the tilting block 302a, since the surface of the tilting block 302a is an inclined surface, the tilting block 302a will move to the right, and while the first return spring 303 is compressed, the locking rod 301 will move synchronously under the connection between the base plate 302b and the first connecting plate 302c.

[0039] Among them, two limit plates 302d are installed on the top of the tilting block 302a. The inner length of the two limit plates 302d is adapted to the diameter of the handle 200. By setting the limit plates 302d, the handle 200 can be limited, so that the tilting block 302a can move horizontally.

[0040] Operation process: When in use, the handle 200 is inserted into the insertion slot 101, and the bottom of the handle 200 contacts and squeezes the locking assembly 302. When the locking assembly 302 is squeezed, it will move to the right and compress the first return spring 303, while causing the locking rod 301 to shrink to the inside of the telescopic hole 102, thereby completing the unlocking. When locking is required, the handle 200 moves upward, and the squeezing of the handle 200 is lost. Under the action of the reset force of the first return spring 303, the locking rod 301 and the locking assembly 302 will move, and the locking rod 301 extends out of the telescopic hole 102 to complete the locking operation.

[0041] Example 2

[0042] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fixing mechanism. It also includes a limiting component 400 and a positioning component 500 used in conjunction with each other. By providing the limiting component 400 and the positioning component 500, the handle 200 can be locked after being pressed down. At the same time, by pressing the handle 200 down again, the mounting block 100 and the handle 200 can be unlocked.

[0043] Among them, the limiting component 400 includes a limiting groove 401 opened at the bottom end of the handle 200, a through groove 402 opened on the inner wall of the limiting groove 401, and a limiting component 403 arranged inside the through groove 402; the positioning component 500 includes a through groove 501 opened at the top of the bottom plate 302b, a positioning groove 502 opened at the bottom of the inner cavity of the cavity 103, and a positioning component 503 arranged at the bottom of the inner cavity of the positioning groove 502; after the handle 200 is pressed down to the position of the bottom plate 302b, the handle 200 passes through the through groove 501 and is inserted into the interior of the positioning groove 502. Through the mutual cooperation between the limiting component 403 and the positioning component 503, the handle 200 and the mounting block 100 can be locked.

[0044] Specifically, the limiting assembly 403 includes a positioning plate 403a installed on the inner wall of the through groove 402, a second return spring 403b is installed on one side of the positioning plate 403a, a second connecting plate 403c is installed on one end of the second return spring 403b, a connecting rod 403d is installed on one side of the second connecting plate 403c, and an extrusion block 403e is installed on one end of the connecting rod 403d; the second connecting plate 403c and the extrusion block 403e are both slidably connected to the inside of the through groove 402; the positioning assembly 503 includes a vertical rod 503 a, positioning block 503b and disengagement block 503c, one end of the vertical rod 503a is installed at the bottom of the inner cavity of the positioning groove 502, the other end of the positioning block 503b is connected to the positioning block 503b, and the disengagement block 503c is slidably sleeved on the surface of the vertical rod 503a; the maximum outer diameter of the positioning block 503b and the disengagement block 503c is adapted to the inner diameter of the limiting groove 401, and the outer edges of the positioning block 503b and the disengagement block 503c are arc-shaped; after the handle 200 is pressed down to the position of the bottom plate 302b, the handle 200 passes through the through groove 501 Inserted into the interior of the positioning groove 502 and continue to move downward until the positioning block 503b contacts and squeezes the extrusion block 403e. Under the squeezing of the positioning block 503b, the extrusion block 403e shrinks to the inner wall of the through groove 402. When the extrusion block 403e moves away from the positioning block 503b, the extrusion block 403e extends from the interior of the through groove 402. At this time, the top of the extrusion block 403e contacts and engages with the bottom of the positioning block 503b, thereby completing the alignment between the mounting block 100 and the handle 200. Fixed; when unlocking is required, the handle 200 is pressed down again, the squeezing block 403e contacts the disengaging block 503c and shrinks to the inside of the through groove 402, then extends to contact and clamp the disengaging block 503c, and then the handle 200 is pulled up until the disengaging block 503c is connected to the positioning block 503b. At this time, the squeezing block 403e disengages from the positioning block 503b along the outer edge of the disengaging block 503c and the positioning block 503b, and the handle 200 is continuously pulled up to complete the unlocking between the mounting block 100 and the handle 200.
