[0035] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0036] Reference Figure 1-3 The handle in this case consists of three main parts: housing 100, locking and ejection device, and bracket 600. Housing 100 is the external structure of the handle, and its panel is provided with guide groove 110 and opening, which provides installation space for the movement of bracket 600.

[0037] A locking and ejection device, as shown in the reference Figure 1 , 4 7. Includes: a guide rail 300; a slider 500 slidably mounted on the guide rail 300; an energy storage component 220 disposed at the insertion end of the guide rail 300, which is compressed and stores energy when inserted by the slider 500 to provide an ejection force; and a locking mechanism 400, including an operating component 420 and locking arms 410 movably disposed on both sides of the guide rail 300; wherein, the slider 500 has slots 510 on both sides, and the guide rail 300 has through holes 310 corresponding to the slots 510; in the locked state, the locking arms 410 pass through the through holes 310 and engage the slots 510, preventing the slider 500 from ejecting; pressing the operating component 420 drives the locking arms 410 to disengage from the slots 510 and exit the through holes 310, and after unlocking, the energy storage component 220 releases energy to eject the slider 500.

[0038] Understandably, the guide rail 300 provides a linear track along which the slider 500 can slide. When the slider 500 is inserted into the guide rail 300, the energy storage component 220 located at the insertion end of the guide rail 300 is compressed and stores energy, which provides the elastic force for the subsequent ejection of the slider 500. The locking mechanism 400 consists of an operating component 420 and a locking arm 410, wherein the locking arm 410 is movably disposed on both sides of the guide rail 300. Slots 510 are provided on both sides of the slider 500, and through holes 310 are provided on the guide rail 300 corresponding to the positions of these slots 510. When the device is in the locked state, the locking arm 410 passes through the through holes 310 on the guide rail 300 and engages in the slots 510 of the slider 500, thus effectively preventing the slider 500 from being ejected under the elastic force of the energy storage component 220. When the slider 500 needs to be removed, the user only needs to press the operating component 420. The operating component 420 will drive the locking arm 410 to disengage from the slot 510 and exit the through hole 310. At this time, the locking state is released, and the energy storage component 220 immediately releases the previously stored energy, thereby automatically ejecting the slider 500 from the guide rail 300.

[0039] In some embodiments, refer to Figure 1 , 2The locking and ejection devices described in sections 3 and 6 are fixedly installed inside the housing 100; the bracket 600 includes a bracket body 610, a connecting part 620, and a limiting protrusion 630. One end of the bracket body 610 is hinged to the sliding member 500 of the locking and ejection device, and the other end is connected to the limiting protrusion 630 through the connecting part 620; wherein, in the assembled state, the bracket body 610 is located outside the housing 100, and the limiting protrusion 630 extends into the inside of the housing 100 through the opening and moves along the guide groove 110; the bracket 600 and the sliding member 500 are configured to be inserted into the housing 100 and the guide rail 300 simultaneously. When the bracket 600 is fully inserted into the position, the sliding member 500 is locked and fixed by the locking arm 410 of the locking and ejection device. With the handle assembled, the bracket body 610 is located on the outside of the housing 100, while the limiting protrusion 630 extends into the inside of the housing 100 through the opening on the panel of the housing 100 and can move along the guide groove 110. When the user operates, the bracket 600 and the slider 500 are simultaneously inserted into the housing 100 and the guide rail 300. That is, when the user pushes the hinge end of the bracket 600 and the slider 500, the slider 500 enters the guide rail 300, and at the same time, the limiting protrusion 630 of the bracket 600 moves along the guide groove 110. When the bracket 600 is fully inserted, the slider 500 is locked and automatically clamped to the locking arm 410 in the ejection device, thereby achieving a stable installation of the bracket 600 on the housing 100. Similarly, when disassembly is required, simply press the operating part 420 on the handle, the locking arm 410 will release the slider 500, and the energy storage component 220 will then release energy and automatically eject a certain distance, causing the slider 500 and the bracket 600 to eject simultaneously.

[0040] The handles in this case include, but are not limited to, game controllers, as well as power tool handles, medical device handles, photographic equipment handles, sports equipment handles, and household appliance handles.

[0041] It should be further noted that the bracket body 610 is equipped with an external interface for connecting external devices, such as a cover plate. On the other side of the cover plate, an adhesive structure can also be installed, allowing the cover plate to connect to mobile devices such as phones and tablets. For example, after attaching the phone to the cover plate, refer to... Figure 6 By separating the hinged bracket body 610 from the slider 500, and since the bracket body 610 is fixedly connected to the cover plate through an external interface, the slider 500 can be moved to realize the function of a mobile phone stand supported by the slider 500, which greatly improves the versatility and ease of use of the handle.

[0042] Specifically, external interfaces can be snap-fit ​​connectors, magnetic connectors, threaded connectors, dovetail joints, quick-release interfaces, or standard electronic interfaces such as USB / Type-C, providing both mechanical connection functionality and electrical signal transmission. Adsorption structures can be vacuum suction cups, miniature powerful magnet arrays, reusable nano-adsorption material layers, electrostatic adsorption sheets, or physical clamping structures with elastic clips. These structures ensure a secure and detachable connection between the mobile device and the cover without damaging the device surface.

[0043] In some embodiments, referring to 1 and 4, a fixing frame 200 is further included, and the guide rail 300 is fixedly connected to the fixing frame 200; the energy storage component 220 includes a coil spring 221 and a flexible belt 222; a fixing seat 210 is provided on the side of the fixing frame 200 near the energy storage component 220, and the two ends of the coil spring 221 are fixedly installed through the fixing seat 210. The guide rail 300 and the fixing frame 200 can be fixedly connected by means of bonding, welding, etc., to form a stable overall structure, while the fixing frame 200 is fastened to the housing 100 by screws. This connection method facilitates assembly and disassembly, while ensuring the stability of the entire mechanism within the housing 100. The energy storage component 220 is specifically composed of two parts: the coil spring 221 and the flexible belt 222, where the coil spring 221 provides the necessary elastic potential energy, and the flexible belt 222 is responsible for force transmission. To ensure the stable operation of the coil spring 221, the fixing frame 200 is provided with a fixing seat 210 on the side near the energy storage component 220, and the two ends of the coil spring 221 are fixed by the fixing seat 210. When the sliding member 500 is inserted into the guide rail 300, the flexible belt 222 is driven and causes the coil spring 221 to deform and store energy; when the locking mechanism 400 is unlocked, the coil spring 221 releases energy and pushes the sliding member 500 out through the flexible belt 222.

[0044] To facilitate the engagement between the slider 500 and the energy storage component 220, the slider 500 has a concave structure on the side away from the energy storage component 220, and guide portions 520 extend on both sides of the concave structure, which slide in engagement with the guide rail 300; the slot 510 is formed on the guide portion 520. The concave structure mainly serves as a clearance area, allowing the flexible belt 222 to pass smoothly. Since the coil spring 221 is located on the side of the track away from the housing 100 and is slightly higher, while the flexible belt 222 is located on the side of the track closer to the housing 100, when the slider 500 is inserted, without the concave structure, the bottom of the slider 500 on the side closer to the housing 100 would directly contact the housing 100, thereby increasing the frictional resistance and wear risk of the flexible belt 222. The presence of the concave structure provides a dedicated, interference-free channel for the flexible belt 222, ensuring that it can freely expand and contract without obstruction during the movement of the slider 500. Based on this, guide portions 520 are formed by the outward extension of the concave structure on both sides of the slider 500. These guide portions 520 slide in conjunction with the guide rail 300 to ensure that the slider 500 moves smoothly along the predetermined track during insertion and ejection, preventing jamming or deviation. It is worth noting that the slots 510 are formed on these guide portions 520. When the slider 500 is fully inserted, the locking arm 410 can pass through the through hole 310 of the guide rail 300 and accurately engage with these slots 510, thereby achieving reliable locking of the slider 500.

[0045] In some embodiments, refer to Figure 1 , 4 7. The locking mechanism 400 includes: one end of the locking arm 410 is hinged to the fixing frame 200, and the other end passes through the through hole 310 and engages with the slot 510; the operating member 420 includes a pressing end 421, a transmission rod 422, and two connecting arms 423 hinged to the transmission rod 422, the free ends of the two connecting arms 423 being respectively hinged to the end of the corresponding locking arm 410 near the slot 510. It can be understood that the pressing end 421 is outside the housing 100 for user operation, the transmission rod 422 is responsible for transmitting the pressing force applied by the user to the connecting arms 423, and the free ends of the two connecting arms 423 are respectively hinged to the end of the corresponding locking arm 410 near the slot 510. When the user presses the pressing end 421 of the operating component 420, the transmission rod 422 will drive the two connecting arms 423 to move. The connecting arms 423 push the locking arm 410 to rotate around the hinge point with the fixed frame 200 through the hinge point, so that the locking end of the locking arm 410 disengages from the slot 510 and exits the through hole 310, thereby releasing the locking state of the sliding component 500. At the same time, the energy storage component 220 releases energy to push the sliding component 500 out.

[0046] In some embodiments, refer to Figure 7 The locking arm 410 includes an arc-shaped sliding portion 411 and an abutment portion 412 located at the end of the sliding portion 411. The sliding portion 411 is arc-shaped and faces the through hole 310, serving to guide the insertion of the sliding member 500. The abutment portion 412 is connected to the sliding portion 411 and serves to lock the sliding member 500. The slot 510 includes a beveled portion 511 corresponding to the sliding portion 411 and a locking surface 512 corresponding to the abutment portion 412. The beveled portion 511 guides the movement of the locking arm 410, and the locking surface 512 cooperates with the abutment portion 412 to form a locking structure. It can be understood that the sliding portion 411 is mainly used to guide the smooth transition when the sliding member 500 is inserted. When the sliding member 500 is inserted into the guide rail 300, the slot 510 on the sliding member 500 will first contact the arc-shaped sliding portion 411 of the locking arm 410. Correspondingly, the abutment portion 412 is connected to the sliding portion 411, and its main function is to lock the sliding member 500, preventing it from popping out under the elastic force of the energy storage component 220. The slot 510 includes two corresponding functional areas: a beveled surface 511 corresponding to the sliding portion 411 and a locking surface 512 corresponding to the abutment portion 412. The beveled surface 511 has a specific tilt angle to guide the sliding portion 411 of the locking arm 410 to slide smoothly along the bevel, while the locking surface 512 cooperates with the abutment portion 412 to form a solid locking structure, ensuring that the sliding member 500 will not pop out accidentally in the locked state.

[0047] In some embodiments, the abutment portion 412 is an arc-shaped surface, with the hinge point between the locking arm 410 and the fixing frame 200 as its center; the locking surface 512 is an arc-shaped surface that matches the abutment portion 412, allowing the two to fit tightly together in the locked state. It should be noted that the rotational trajectory of the locking arm 410 is arc-shaped. To ensure that the abutment portion 412 can contact the slot 510 along its natural movement path during locking, the abutment portion 412 is set as an arc-shaped surface. Correspondingly, the locking surface 512 is an arc-shaped surface that matches the abutment portion 412, thereby enabling the two to achieve maximum area contact in the locked state, improving the firmness and reliability of the locking. Since the arc center of the abutment portion 412 coincides with the rotation center of the locking arm 410, this means that in the locked state, no matter how much elastic force is applied by the energy storage component 220, the abutment portion 412 will stably abut against the locking surface 512, and will not generate any torque that would cause the locking arm 410 to rotate out, unless the connecting arm 423 is actively driven by the operating component 420 to push the locking arm 410 to rotate.

[0048] In some embodiments, refer to Figure 4A first elastic element 424 is connected between the two connecting arms 423. The first elastic element 424 is in a pre-tightened state, which provides the return force for the locking arm 410 to enter the slot 510 and enables the operating member 420 to automatically reset after the press is released. It can be understood that the first elastic element 424 mainly has two functions: First, it provides the return force for the locking arm 410 to enter the slot 510, ensuring that during the insertion of the sliding member 500, the locking arm 410 can automatically rebound under the guidance of the inclined surface 511 after being temporarily pushed away by the sliding member 500, and the abutment part 412 can be engaged with the locking surface 512 to achieve reliable locking; Second, the first elastic element 424 can also enable the operating member 420 to automatically reset to its original position after the user releases the press, preparing for the next operation. This elastic reset mechanism forms a complete automated cycle: when the user presses the operating element 420, the connecting arm 423 pushes the locking arm 410 out of the slot 510, and at the same time the first elastic element 424 is further compressed; when the user releases the press, the first elastic element 424 releases energy to push the connecting arm 423 and the operating element 420 back to the initial position, and at the same time pushes the locking arm 410 back to the locked state.

[0049] In some embodiments, the transmission rod 422 and the two connecting arms 423 are integrally formed and made of materials with good elastic properties, such as high-elasticity engineering plastics or special elastic alloys. This integrated design not only simplifies the manufacturing process and reduces assembly steps, but also provides a basic reset function through the elastic properties of the material itself. Specifically, when the user presses the operating component 420, the transmission rod 422 drives the two connecting arms 423 to separate outwards, and the connecting arms 423 push the locking arm 410 out of the slot 510; once the user releases the pressure, the connecting arms 423 can automatically return to their original position based on the elastic properties of the material itself, while simultaneously driving the locking arm 410 back to the locked state. Although the elasticity of the material itself can achieve the basic function, in order to further improve the performance and long-term reliability, it is preferable to add a first elastic element 424 between the two connecting arms 423, wherein the first elastic element 424 is preferably a spring. The spring not only provides a larger and more stable return force, ensuring that the locking arm 410 can quickly and accurately return to the locked position, but also reduces the fatigue pressure on the material itself, significantly extending the service life of the entire mechanism.

[0050] In some embodiments, refer to Figure 4The pressing end 421 has a rectangular structure, arranged around the coil spring 221, and has clearance slots 4211 on both sides of the rectangular structure. The two ends of the coil spring 221 are located in the clearance slots 4211, and the width of the clearance slots 4211 is greater than the diameter of the shaft to provide sufficient travel space to ensure that the locking arm 410 can completely disengage from the slot 510 when pressed. It should be noted that the pressing end 421 adopts a rectangular structure and is arranged around the coil spring 221. This method effectively utilizes space and makes the entire mechanism more compact. The width of the clearance slots 4211 is greater than the diameter of the shaft, providing sufficient travel space to ensure that when the user presses the operating component 420, the transmission rod 422 can drive the connecting arm 423 to move fully, thereby allowing the locking arm 410 to completely disengage from the slot 510 and achieve a reliable unlocking effect. If the clearance 4211 is too small, the locking arm 410 may not be able to completely disengage from the slot 510 when pressed, causing the slider 500 to fail to pop out smoothly; while if the clearance 4211 is too large, it may cause the structure to become loose or unnecessary material waste.

[0051] In addition, the coil spring 221 is positioned at the upper part of the handle, i.e., the upper part when in use. Integrating the pressing end 421 with the coil spring 221 makes the entire operation highly ergonomic. When the user holds the handle normally, the thumb or index finger can naturally fall on the pressing end 421. There is no need to deliberately adjust the grip posture. The unlocking operation can be completed with just a slight press, which greatly improves the convenience of use.

[0052] In some embodiments, refer to Figure 1 , 38. The handle also includes a stop assembly 700 located on the housing 100; the stop assembly 700 includes: a stop button 710, which is laterally slidably disposed on the housing 100; a stop plate 720, the middle of which is rotatably disposed on a pivot on the housing 100; a second elastic member 730, disposed on the stop plate 720 at a position between the pivot and the stop protrusion 721, one end of which is connected to the stop plate 720 and the other end of which is connected to the housing 100, and is in a compressed state; the first end of the stop plate 720 abuts against the stop button 710; the second end of the stop plate 720 forms the stop protrusion 721, which is located in the guide groove 110; in the non-operating state, the second elastic member 730... The stop plate 720 is driven to the first position, so that the stop protrusion 721 is located in the guide groove 110 and blocks the limiting protrusion 630 of the bracket 600 from moving out along the guide groove 110, and the stop button 710 abuts against the first end of the stop plate 720; when the stop button 710 is operated to slide laterally towards the stop plate 720, the stop button 710 pushes the first end of the stop plate 720, so that the stop plate 720 overcomes the elastic force of the second elastic member 730 and rotates around the pivot to the second position. The stop protrusion 721 then exits the guide groove 110, releasing the obstruction of the limiting protrusion 630, so that the bracket 600 can move out along the guide groove 110.

[0053] Understandably, referring to Figure 8 The first end of the stop plate 720 abuts against the stop button 710, while the second end has a stop protrusion 721 located within the guide groove 110, used to prevent the movement of the limiting protrusion 630 of the bracket 600. One end of the second elastic member 730 is connected to the stop plate 720, and the other end is connected to the housing 100, and it is in a compressed state. This pre-compression state ensures that the second elastic member 730 always generates a force to push the stop plate 720 back to its default position. In the non-operating state, the second elastic member 730 drives the stop plate 720 to the first position. At this time, the stop protrusion 721 is located within the guide groove 110 and effectively prevents the limiting protrusion 630 of the bracket 600 from moving out along the guide groove 110. Simultaneously, the stop button 710 and the first end of the stop plate 720 remain in contact, forming a stable locking structure. When the user needs to pop out the bracket 600, simply operate the stop button 710 and slide it laterally towards the stop plate 720. The stop button 710 will push the first end of the stop plate 720, causing the stop plate 720 to overcome the elastic force of the second elastic element 730 and rotate around the axis to the second position. This rotational action will cause the stop protrusion 721 to exit the guide groove 110, thereby releasing the obstruction of the limiting protrusion 630, allowing the bracket 600 to pop out smoothly along the guide groove 110 under the push of the internal mechanism.
