[0055] The basic embodiment of the present invention provides a rotating stone extraction basket, referring to Figure 1-Figure 8 ,include:

[0056] The handle housing 100 is provided with an inner cavity 110 and a front opening 120 and a rear opening 130 at the front and rear ends respectively, and the front opening 120 and the rear opening 130 are both connected to the inner cavity 110;

[0057] The basket portion 510 is disposed in front of the handle housing 100 . A core wire extends backward from the basket portion 510 . The core wire passes through the front opening 120 and extends into the inner cavity 110 .

[0058] A rotating member 600 is connected to the rear end of the core wire. The rotating member 600 is rotatably disposed at the rear opening 130. The rotation of the rotating member 600 can drive the basket portion 510 to rotate.

[0059] The movable bracket 300 is partially or entirely disposed in the inner cavity 110. The movable bracket 300 can slide back and forth relative to the handle housing 100 and can pass through the front opening 120. The side of the movable bracket 300 is provided with a mounting groove 310.

[0060] The fixed bracket 200 is disposed in the inner cavity 110 and is detachably fixedly connected to the handle housing 100. The fixed bracket 200 is located between the movable bracket 300 and the rotating member 600. The front end of the fixed bracket 200 is disposed in the mounting groove 310, and the rear end of the fixed bracket 200 contacts the front end of the rotating member 600.

[0061] The front guide tube 720 is sleeved outside the core wire, and is connected to the movable bracket 300 and can slide with the movable bracket 300. The movable bracket 300 slides forward and backward relative to the handle housing 100 to gradually retract and release the front guide tube 720 into and out of the basket part 510.

[0062] The beneficial effects of the present invention are as follows:

[0063] The user can press the movable bracket 300 to drive the front guide tube 720 to slide back and forth relative to the core wire, thereby gradually retracting and releasing the basket portion 510, and can drive the basket portion 510 to rotate by rotating the rotating member 600. In this way, during the stone removal process, the user can adjust the size of the basket gap in the basket portion 510 and the angle of the basket gap relative to the stone according to the size and position of the stone, thereby facilitating rapid fixation of the stone, effectively reducing the difficulty of the operation and reducing the time of the operation.

[0064] The setting of the front opening 120 and the movable bracket 300 being able to slide through the front opening 120 facilitate the installation of the rotating member 600, the fixed bracket 200 and the movable bracket 300. The rotating member 600, the fixed bracket 200 and the movable bracket 300 can all be set into the inner cavity 110 through the front opening 120, which is convenient for installation.

[0065] The provision of the fixed bracket 200 can facilitate the limiting of the rotating member 600 , so that the rotating member 600 can be conveniently rotated and disposed at the rear opening 130 .

[0066] The installation groove 310 is provided to more efficiently utilize the space of the inner cavity 110 and also facilitate the installation between the fixed bracket 200 and the movable bracket 300 .

[0067] It can be understood that the inner cavity can be used to accommodate the rotating part, the fixed bracket and the movable bracket; the fixed bracket and the movable bracket can be partially located in the inner cavity and partially located outside the inner cavity; the fixed bracket and the movable bracket can also be located in the inner cavity as a whole.

[0068] It can be understood that the front opening is used to accommodate the rotating part, the fixed bracket and the movable bracket to pass through and enter the inner cavity during the product installation process. During the use process after the product is installed, the front opening accommodates the movable bracket whose sliding stroke is limited by the fixed bracket and the limit assembly during the sliding process. That is, during the forward sliding process of the movable bracket, the front end of the movable bracket or the part close to the front end can extend forward from the front opening. During the backward sliding process of the movable bracket, the front end of the movable bracket or the part close to the front end can be retracted backward into the front opening. When the movable bracket is in the final position of the sliding stroke, the front end of the movable bracket can be in front of the front opening or in the rear of the front opening. At this time, the distance between the front end of the movable bracket and the front opening can be smaller, and the distance can be limited to within one tenth of the front and rear length of the movable bracket, and the distance can be zero.

[0069] It can be understood that the cross-sectional shape of the inner cavity can correspond to the cross-sectional shape of the rotating part, the fixed bracket and the movable bracket. The cross-section takes the front-to-back direction as the normal direction, and the cross-section is set to be non-circular, preferably a symmetrical shape such as a rectangle or a waist. Under this setting, the rotating part, the fixed bracket and the movable bracket will not rotate around the front-to-back direction during the process of being placed in the inner cavity, making the installation more convenient, and the rotating part, the fixed bracket and the movable bracket are more closely matched in the inner cavity, and the rotating part, the fixed bracket, the movable bracket and the handle shell are also more closely matched.

[0070] For the expansion of the basic implementation example, refer to Figure 1-Figure 3 , the rotating member 600 comprises:

[0071] The embedded part 610 and the knob part 620 are arranged at the front and rear, the embedded part 610 is arranged at the rear end of the inner cavity 110, the knob part 620 passes through the rear opening 130 and extends to the rear of the handle shell 100, the rear end of the embedded part 610 can abut against the inner wall of the rear end of the handle shell 100, the cross-sectional area of ​​the embedded part 610 is larger than the cross-sectional area of ​​the knob part 620, and the cross-sectional direction is normal to the front-to-rear direction.

[0072] Under this setting, when the fixing bracket 200 is fixedly connected to the handle shell 100, the fixing bracket 200 can abut against the front end of the embedded portion 610 by abutting, so that the rear end of the embedded portion 610 abuts against the inner wall of the rear end of the handle shell 100, and the rotating member 600 can be stably rotated under the action of the human hand, and the user can stably rotate the basket portion 510 by turning the knob portion 620.

[0073] The cross-sectional area of ​​the embedded portion 610 is larger than the cross-sectional area of ​​the knob portion 620, so that when the embedded portion 610 is pressed by the fixing bracket 200, the knob portion 620 can pass through the rear opening 130, and the embedded portion 610 is blocked by the rear end of the handle housing 100. This arrangement facilitates the installation of the rotating member 600 from the front opening 120. The rear opening 130 can be a round hole.

[0074] It can be understood that an anti-foolproof protrusion can be provided at the rear end of the fixed bracket, and an anti-foolproof groove for accommodating the anti-foolproof protrusion to be buckled into can be provided at the front end of the rotating part. A compression spring can be provided between the inner wall at the rear end of the handle shell and the embedded part. The elastic force of the compression spring makes the anti-foolproof protrusion buckle into the anti-foolproof groove under normal conditions. At this time, there can be a gap between the rear end of the embedded part and the inner wall at the rear end of the handle shell for accommodating the compression spring. When the user needs to rotate the rotating part, the knob part can be pulled back and then rotated. This setting is to maintain the circumferential position of the rotating part when there is no need to rotate the rotating part, thereby maintaining the circumferential position of the basket part, and the circumferential direction is the circumferential direction with the front-to-back direction as the axis.

[0075] For the expansion of the basic implementation example, refer to Figure 3 , the core wire includes:

[0076] The body 520 and the steel pipe 530 are riveted at the rear end of the body 520 and the front end of the steel pipe 530, and the rear end of the steel pipe 530 is detachably fixedly connected to the rotating member 600. Under this arrangement, the body 520 of the core wire is relatively softer than the steel pipe 530, and the steel pipe 530 is more convenient to be fixedly connected to the rotating member 600.

[0077] For the expansion of the basic implementation example, refer to Figure 3 The rear end of the steel pipe 530 is inserted into the rotating member 600, and the rotating member 600 is provided with a top screw for fixing the rear end of the steel pipe 530. The top screw fixation method can quickly complete the fixed connection between the steel pipe 530 and the rotating member 600, and can facilitate disassembly for parts recovery or replacement.

[0078] As an extension of the basic embodiment, the rear end of the fixed bracket is pressed against the front end of the rotating member. Under this configuration, the pressing of the fixed bracket can provide appropriate damping for the rotation of the rotating member, and the rotating member is not easy to move in the inner cavity.

[0079] For the expansion of the basic implementation example, refer to Figure 1-Figure 3 A positioning hole 140 is provided on the handle housing 100, a spring sheet 210 is provided on the fixing bracket 200, and a button 220 is provided on the spring sheet 210. The button 220 can be buckled into the positioning hole 140 from the inside to the outside, and the deformation of the spring sheet 210 can make the button 220 leave the positioning hole 140 from the outside to the inside.

[0080] The spring sheet 210 provides power for the button 220 to maintain a fixed state after entering the positioning hole 140. Under this setting, when the fixed bracket 200 is set into the inner cavity 110, the inner wall of the handle shell 100 can abut against the button 220 to deform the spring sheet 210 inwardly. When the fixed bracket 200 moves to a position that allows the button 220 to be set into the positioning hole 140, the spring sheet 210 returns to its original position so that the button 220 is buckled into the positioning hole 140. The installation process of the fixed bracket 200 is very convenient, and the fixed state between the fixed bracket 200 and the handle shell 100 is stable. The relatively fixed state between the fixed bracket 200 and the handle shell 100 can be released by manually pressing the button 220 inward, and the rotating part 600, the fixed bracket 200 and the movable bracket 300 can be taken out.

[0081] It is understandable that the positioning assembly may also be a structure of other forms, for example, an elastic protrusion may be provided on the inner wall of the handle housing and then cooperate with a buckle groove provided on the outer wall of the fixing bracket.

[0082] It can be understood that the inward and outward directions in the technical solution of the present invention are based on the radial direction of the front-rear direction, radially outward is the outward direction, and radially inward is the inward direction.

[0083] It is understandable that the fixing bracket can be made of plastic material to facilitate the formation of the spring sheet and the button, and the button, the spring sheet and the fixing bracket can be formed in one piece.

[0084] For the expansion of the basic implementation example, refer to Figure 1-Figure 8 The movable bracket 300 is provided with an inner slide groove 330 extending forward and backward, and a stopper 340 is formed on the movable bracket 300 corresponding to the rear end of the inner slide groove 330;

[0085] A front stopper 230 and a rear stopper 240 are provided on the fixed bracket 200 at intervals in front and back. The front stopper 230 is located in the inner slide groove 330, and the rear stopper 240 is located behind the stopper 340.

[0086] A limiting rod 400 is disposed in the inner slide groove 330 and is located between the front stop block 230 and the stop portion 340 . The dimension of the limiting rod 400 in the front-to-back direction is not greater than the distance between the front stop block 230 and the stop portion 340 in the front-to-back direction.

[0087] Under this setting, it is convenient to install the movable bracket 300 and the fixed bracket 200 before entering the inner cavity 110. First, the limit rod 400 is set into the inner slide groove 330, and then the front stop block 230 is also set into the inner slide groove 330, so that the limit rod 400 is located between the front stop block 230 and the stop portion 340. The setting of the limit rod 400 is to limit the sliding stroke of the movable bracket 300 relative to the fixed bracket 200. Limit rods 400 of different lengths can be replaced according to usage requirements, and this product can include multiple products, which correspond to different sliding strokes of the movable bracket 300. Since the spacing between the front stop block 230 and the stop portion 340 will change as the movable bracket 300 slides relative to the fixed bracket 200, the minimum value of the spacing can be the length value of the limit rod 400, and the maximum value of the spacing can be the spacing value between the front stop block 230 and the stop portion 340 when the stop portion 340 is blocked by the rear stop block 240.

[0088] It is understandable that the limit assembly can also be a structure of other forms, and the limit rod can be omitted, which can be achieved by setting an intermediate slider between the front block and the rear block in the inner slide groove, or by directly using the stopper as the intermediate slider. In this case, the distance between the front block and the rear block needs to be adjusted, and specifically, the distance between the front block and the rear block can be reduced to adapt to the change of omitting the limit rod. Obviously, the setting of the limit rod can more flexibly adjust the stroke of the movable bracket or formulate products of various specifications according to different needs.

[0089] For the expansion of the basic implementation example, refer to Figure 3 and Figure 8 A limiting recess 320 is provided at the rear end of the movable bracket 300, and the button 220 can be set in the limiting recess 320. Under this setting, it is convenient to limit the relative position of the movable bracket 300 and the fixed bracket 200 in the circumferential direction with the front-rear direction as the axis; the shape of the limiting recess 320 can correspond to the shape of the button 220, and the surfaces of the two can fit together; the limiting recess 320 can be located at the rear end of the movable bracket 300.

[0090] It can be understood that the side portion in the technical solution of the present invention is based on the radial direction in the front-rear direction, which corresponds to the lateral direction, that is, the lateral direction in the front-rear direction, and the opening direction of the installation groove can be from the lateral direction from the outside to the inside.

[0091] It can be understood that the inner slide groove and the mounting groove can be connected, and the inner slide groove can be arranged on the inner wall of the mounting groove corresponding to one end of the pressing portion.

[0092] For the expansion of the basic implementation example, refer to Figure 1-Figure 3The handle housing 100 is provided with a guide groove 150 extending forward and backward, the guide groove 150 extends to the front end of the handle housing 100 and communicates with the front opening 120, the guide groove 150 communicates with the inner cavity 110, and the movable bracket 300 includes a slider portion 350, and the slider portion 350 can slide in the guide groove 150. Under this setting, the handle housing 100 can slide forward and backward according to the set path, and the movable bracket 300 can only set the slider portion 350 in the guide groove 150, and the other parts are all arranged in the handle housing 100. Combined with the setting method of the fixed bracket 200 and the rotating member 600, the handle housing 100 has fewer openings, and the appearance of the entire product can be mainly based on the shape of the handle housing 100, which can be made very beautiful.

[0093] For the expansion of the basic implementation example, refer to Figure 1-Figure 3 The movable bracket 300 further includes a pressing portion 360 protruding from the slider portion 350. The pressing portion 360 is located outside the handle housing 100. The pressing portion 360 is provided with a resistance-increasing protrusion 370. Under this arrangement, the user can more conveniently slide the movable bracket 300 by pressing the pressing portion 360. The direction mark on the slider portion 350 may include an opening mark and a closing mark. The closing mark is located in front of the pressing portion 360, and the opening mark is located behind the pressing portion 360.

[0094] For the expansion of the basic implementation example, refer to Figure 1-Figure 7 The rotating stone extraction basket also includes:

[0095] The mounting sleeve 710 is located in front of the movable bracket 300. The front end of the movable bracket 300 includes a threaded sleeve 380. The mounting sleeve 710 is connected to the threaded sleeve 380 by threaded connection. The rear end of the front guide tube 720 passes through the mounting sleeve 710 and is fixedly connected to the threaded sleeve 380.

[0096] The rear guide tube 730 is located behind the threaded sleeve 380 and is sleeved outside the core wire. The front end of the rear guide tube 730 is fixedly connected to the threaded sleeve 380.

[0097] The protective sleeve 740 is located in front of the threaded sleeve 380 and is sleeved outside the front guide tube 720 . The rear end of the protective sleeve 740 passes through the installation sleeve 710 and is fixed between the installation sleeve 710 and the threaded sleeve 380 .

[0098] Under this setting, the movable bracket 300 can drive the front guide tube 720 to move forward and gradually retract the basket part 510, and move backward to gradually release the basket part 510.
