[0026] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0027] like Figures 1 to 6The embodiment of the utility model shown preferably provides a toilet brush head anti-detachment clamping structure, including a grip rod 1 and a clamping member arranged at one end of the grip rod 1 for clamping the brush head, wherein a clamping assembly is arranged at one end of the grip rod 1, and the clamping assembly includes two clamping members 2 arranged to rotate relative to each other, and the two clamping members 2 can rotate relative to each other to fit together or rotate apart, and a brush head clamping area 3 is formed between the two clamping members 2; wherein, a movable assembly 4 that can elastically stretch and contract along its axial direction is movably arranged in the grip rod 1, and two guide bevel grooves 5 are respectively provided on the movable assembly 4, and one end of the two clamping members 2 is respectively provided with a movable shaft 6, and the movable shaft 6 is movably arranged in the guide bevel groove 5 in a one-to-one correspondence, and the two clamping members 2 are driven to rotate and open and close by moving along the guide bevel groove 5 through the movable shaft 6, and when the movable assembly 4 is elastically moved toward the clamping assembly direction, the two clamping members 2 are kept in a fitted and closed state through the guide limit of the guide bevel groove 5.

[0028] Specifically, the opening and closing rotation of the two clamping members are limited respectively by the guidance of the guiding inclined grooves in the movable component, thereby effectively enhancing the firmness of the clamping members on the brush head, thereby avoiding the problem of the brush head being easily loosened due to relying solely on the spring to maintain the clamping closed state; and the utility model adopts the movable component to elastically move toward the clamping component to maintain the closed clamping state of the two clamping members, thereby forming a more reasonable front-pull locking and clamping, rear-pull unlocking and loosening structure, that is, when the movable component elastically moves forward in the direction of the clamping component, the two clamping members are in a coordinated state of locking and clamping the brush head, conversely, when the brush head needs to be disassembled, the movable component is compressed by force and elastically moves backward in the direction away from the clamping component, and the two clamping members are in an open state.

[0029] Furthermore, a limited movable groove 11 is provided in the grip 1, and the clamping assembly is movably provided in the limited movable groove 11 so that it can move up and down along the axis of the grip 1. Specifically, the clamping assembly can move up and down along the limited movable groove, so that the two clamping members in the clamping assembly can move up and down accordingly, and the movable shafts on the two clamping members respectively cooperate with the guide inclined grooves in the movable assembly, and cooperate with the elastic abutment of the movable assembly, so that the two clamping members are in an openable and closable state that can move up and down relative to the movable assembly;

[0030] Furthermore, when the utility model is in use, there is no need for the user to manually drive the movable component to move to control the opening and closing of the two clamping parts to clamp the brush head. That is, the connecting part of the brush head can be directly pressed against the clamping part so that the two clamping parts are driven to open by force. When the connecting part of the brush head moves into the brush head clamping area, the clamping part is reset by the elastic action of the movable component to maintain the clamped state, thereby effectively and quickly installing the brush head.

[0031] Furthermore, the grip 1 has a cavity 12, and one end of the grip 1 is penetrated by an inlet 13 connected to the cavity 12, the limit movable groove 11 is formed in the cavity 12, the clamping assembly and the movable assembly 4 are respectively arranged in the cavity 12, and the brush head clamping area 3 is located near the inlet 13. When the clamping assembly clamps and fixes the brush head, one end of the grip 1 is in conflict with the brush head limit. Specifically, when the connecting part of the brush head enters from the inlet and is clamped in the brush head clamping area between the two clamps, the lower end of the grip 1 is in conflict with the upper limit of the brush head, thereby realizing the double limit locking of the brush head;

[0032] That is, the connecting part of the brush head is restricted and clamped in the brush head clamping area, so that the brush head cannot move downward and away from the grip rod. At this time, the upper side of the brush head contacts the lower end of the grip rod, and the brush head cannot continue to move in the direction of the grip rod, driving the two clamping parts to open again, thereby firmly clamping the brush head and avoiding the problem of the brush head falling off easily.

[0033] Furthermore, the movable assembly 4 includes a movable rod 41 and a first spring 42, a slot 43 is formed through one side of the movable rod 41, a limit block 44 is provided in the slot 43 on the grip 1, the first spring 42 is provided in the slot 43 and abuts between the limit block 44 and the movable rod 41, and two guide inclined grooves 5 are respectively formed on the movable rod 41. Specifically, the first spring is used to enable the movable rod to be elastically telescopic along the axial direction of the grip.

[0034] Furthermore, a positioning protrusion 45 is protruded outwardly from one side of the slot 43, and the first spring 42 is sleeved on the positioning protrusion 45. Then, the positioning and guiding installation of the first spring is realized through the positioning flange.

[0035] Further, the clamping member 2 includes a connecting rod 21 and a clamping head 22 disposed at one end of the connecting rod 21, a rotating shaft 23 protrudes from one side of the connecting rod 21, and the connecting rod 21 is provided with a first connecting block 24, a second connecting block 25 is provided on the first connecting block 24, and a limiting hole 26 that can cooperate with the rotating shaft 23 is provided on the second connecting block 25; the two clamping members 2 are arranged in a cross-displaced distribution, and the rotating shaft 23 of one clamping member 2 is rotatably arranged in the limiting hole 26 of the other clamping member 2. And the second connecting block 25 is movably arranged in the limiting movable groove 11, so that the clamping member can move up and down along the limiting movable groove.

[0036] Furthermore, the two clamping members are arranged in a cross-displaced distribution, and the rotating shaft of one clamping member is rotatably arranged in the limiting hole of the other clamping member to simplify the rotating installation connection of the two clamping members, without the need to install an external rotating shaft accessory.

[0037] Furthermore, the second connection block 25 can be elastically deformed and arranged on the first connection block 24 , and the rotating shaft 23 can be pressed against the second connection block 25 and pass over the second connection block 25 to be accommodated in the limiting hole 26 .

[0038] Furthermore, the movable assembly 4 is provided with notches 46 corresponding to one side of the guide slant groove 5, and the movable shaft 6 is movably accommodated in the guide slant groove 5 through the notches 46, so as to facilitate the installation connection between the movable assembly and the clamping member.

[0039] Furthermore, the handle 1 is provided with a pull rod 91 that can move along its axial direction, and the pull rod 91 is connected to the movable rod 41 and the two can move relatively. Specifically, the upper end of the movable rod is concave with a cavity, the lower end of the pull rod is movably inserted into the groove, and the lower end of the pull rod abuts against the upper side wall of the cavity.

[0040] The user can apply force to move the pull rod to drive the movable rod to move synchronously and compress the elastic force of the first spring, thereby realizing the opening and loosening of the two clamping parts; and when the clamping assembly and the movable assembly cooperate to clamp and fix the brush head, because the pull rod and the movable rod can move telescopically, when the movable rod moves upward under force to compress the elastic force of the first spring, the upper side wall of the concave cavity of the movable rod is separated from the lower end of the pull rod and will not drive the pull rod to move, while the pull rod can drive the movable rod to move and compress the elastic force of the first spring when it moves upward.

[0041] Furthermore, a driving button 92 capable of driving the pull rod 91 to move away from the movable rod 41 is movably provided on one side of the grip 1; wherein a slot hole 93 is provided through one side of the pull rod 91, and an oblique pressing block 94 is provided on one side of the driving button 92 in the slot hole 93, and a second spring 95 is abutted between the pull rod 91 and the grip 1, and the second spring 95 is used to keep the inclined surface of the oblique pressing block 94 pressed against one end of the slot hole 93. Specifically, the user can directly press the driving button, and the inclined surface of the oblique pressing block of the driving button is used to guide and drive the pull rod to move relative to the grip, thereby driving the two clamps to open and loosen the brush head through the transmission of the movable rod.
