[0010] In some embodiments, the frame includes a connecting portion, the transmission member passes through the connecting portion, and the transmission member includes a first end portion and a second end portion located at both ends of the connecting portion;

[0011] Wherein, the locking member is connected to the first end portion, a driving structure is provided at the second end portion, and the driving structure is adapted to receive a driving force.

[0012] In some embodiments, an installation groove is recessed on one side of the connecting portion facing the second end portion, the second end portion passes through the installation groove, an elastic member is disposed in the installation groove, one end of the elastic member is connected to the second end portion, and the other end of the elastic member is connected to the bottom wall of the installation groove.

[0013] In some embodiments, the frame includes a gear position portion extending in a direction parallel to the rotation axis. When the transmission member is in the first position, the gear position portion is within the movement path of the locking member rotating around the rotation axis, thereby restricting the locking member from rotating from the unlocking position to the locking position or from the locking position to the unlocking position around the rotation axis. When the transmission member is in the second position, the gear position portion is outside the movement path of the locking member rotating around the rotation axis.

[0014] In some embodiments, the gear position portion has a first side wall and a second side wall arranged oppositely in the circumferential direction of the rotation axis.

[0020] Correspondingly, the utility model also proposes a signal box installation device, including the installation bracket described in any one of the above embodiments.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] In the technical solution of the present utility model, an installation bracket that is convenient for installation and disassembly is provided. When the installation bracket is not installed, that is, when the installation bracket is in a natural placement state, the elastic member is neither under pressure nor under tension. The transmission member will be in the first position under the drive of the elastic member, and the locking member will be in the unlocked position. When installing the installation bracket, first, an external force needs to be applied to the transmission member (exemplarily, for example, a pressure can be applied to the transmission member). Under the action of the external force, the transmission member will move from the first position to the second position. At the same time, the elastic member will be in a compressed state after being stressed, and the locking member will move from the first position to the second position together with the transmission member. After driving the transmission member to move to the second position, a forward screwing external force is applied to the transmission member. Under the action of the external force, the transmission member will perform a forward locking rotation relative to the frame. At the same time, the locking member will rotate from the unlocked position to the locked position along with the transmission member. In the locked position state, the locking member will abut against the base to fix the frame on the base, realizing the installation of the frame on the base. In addition, after the locking member rotates to the locked position, the external force applied to the transmission member will be removed. When the external force disappears, the elastic member will automatically reset, and the locking member will move from the second position to the first position along with the transmission member. This is beneficial to increasing the pressing force of the locking member on the base, thereby being beneficial to improving the installation stability of the frame on the base. When disassembling the installation bracket, first, an external force needs to be applied to the transmission member (exemplarily, for example, a pressure can be applied to the transmission member). Under the action of the external force, the transmission member will move from the first position to the second position. At the same time, the elastic member will be in a compressed state after being stressed, and the locking member will move from the first position to the second position together with the transmission member. After driving the transmission member to move to the second position, a reverse screwing external force is applied to the transmission member. Under the action of the external force, the transmission member will perform a reverse unlocking rotation relative to the frame. At the same time, the locking member will rotate from the locked position to the unlocked position along with the transmission member. In the unlocked position state, the locking member will disengage from the base, facilitating the removal of the frame from the base, realizing the disassembly of the frame from the base. In addition, after the locking member rotates to the unlocked position, the external force applied to the transmission member will be removed. When the external force disappears, the elastic member will automatically reset, and the locking member will move from the second position to the first position along with the transmission member.

[0023] The operation method of the installation bracket provided by the present utility model is simple, time-saving and labor-saving. Users do not need to use the method of screwing to fix the frame on the base. Only by screwing the transmission member can the frame be detachably connected to the base. Moreover, through the installation bracket provided by the present utility model, a damage-free connection between the frame and the base can be realized, avoiding punching damage to the frame or the base.

[0024] The signal box installation device applying the above installation bracket is convenient for installation and disassembly, time-saving and labor-saving. Description of the Drawings

[0055] The signal box is used to install electronic devices and manage cables. Sockets, small set-top boxes, power supplies, cables, etc. can be installed inside it. The existing embedded signal boxes on the market are usually fixed to the wall panel by screws. Users need to spend a lot of time reading the installation instructions and driving screws during the installation process of the signal box. Moreover, a signal box is equipped with various different types of screws, that is, a signal box needs to be fixed to the wall panel through various different types of screws. The above installation and fixing method of the signal box is not only time-consuming and laborious, but also prone to errors during installation.

[0056] To solve the technical problems that the existing installation and fixing method of the signal box is time-consuming and laborious and prone to errors during the installation process, with reference to Figures 1 to 6, an embodiment of the present utility model provides a mounting bracket, which is used to be assembled on a base 200. The base 200 can be a wall panel, a floor panel, a table panel, a cabinet panel, etc. An installation hole is provided on the base 200, and the mounting bracket can be embedded in the installation hole. For example, when the base 200 is a wall panel, that is, the mounting bracket can be assembled on the wall panel. The mounting bracket includes a frame 100, a transmission member 300, an elastic member 400, and a locking member 500. The frame 100 can be a signal box or a cable bracket. When the frame 100 is a signal box, electronic devices, cables and other structures can be installed inside the signal box to realize the storage of electronic devices, cables and other structures. When the frame 100 is a cable through-wall support bracket, cables can be placed on the cable bracket to realize the support of the cables. It can be understood that the frame 100 can also be other structural products, such as an in-wall power socket frame, etc., which will not be elaborated here one by one. The transmission member 300 can be a screw structure. Exemplarily, for example, the transmission member 300 can be an M6 type screw structure. The transmission member 300 is rotatably connected to the frame 100. The transmission member 300 is configured to rotate relative to the frame 100 about the rotation axis, and the transmission member 300 is further configured to move relative to the frame 100 in a direction parallel to the rotation axis to a first position 600 and a second position 700. The elastic member 400 can be a spring or a spring sheet. The elastic member 400 is connected to the frame 100 and the transmission member 300 to make the transmission member 300 relative to the frame 100 in the first position 600. The locking member 500 can be a fixed iron sheet, or the locking member 500 can also be a fixed stainless steel sheet. The locking member 500 is connected to the transmission member 300 and is configured to be driven by the transmission member 300 to rotate relative to the frame 100 to a locking position 900 or an unlocking position 800, and the locking member 500 can move along a direction parallel to the rotation axis with the transmission member 300 during the process of rotating from the unlocking position 800 to the locking position 900, or from the locking position 900 to the unlocking position 800. Among them, when the locking member 500 is in the locking position 900, it is adapted to abut against the base 200 to position the frame 100 on the base 200. When the locking member 500 is in the unlocking position 800, it is adapted to be separated from the base 200 to enable the frame 100 to be detached from the base 200.

[0057] Specifically, to solve the above problems, in this embodiment, an installation bracket that is convenient for installation and disassembly is provided. When the installation bracket is not installed, that is, when the installation bracket is in a natural placement state, the elastic member 400 is neither under pressure nor under tension. The transmission member 300 will be in the first position 600 under the drive of the elastic member 400, and the locking member 500 will be in the unlocked position 800. When installing the installation bracket, first, an external force needs to be applied to the transmission member 300 (in this embodiment, taking applying pressure to the transmission member 300 as an example). Under the action of the external force, the transmission member 300 will move from the first position 600 to the second position 700. At the same time, the elastic member 400 will be in a compressed state after being stressed, and the locking member 500 will move from the first position 600 to the second position 700 together with the transmission member 300. After driving the transmission member 300 to move to the second position 700, a positive screwing external force is applied to the transmission member 300. Under the action of the external force, the transmission member 300 will perform a positive locking rotation relative to the frame 100. At the same time, the locking member 500 will rotate from the unlocked position 800 to the locked position 900 along with the transmission member 300. In the state of the locked position 900, the locking member 500 will abut against the base 200 to fix the frame 100 on the base 200, realizing the installation of the frame 100 on the base 200. In addition, after the locking member 500 rotates to the locked position 900, the external force applied to the transmission member 300 will be removed. When the external force disappears, the elastic member 400 will automatically reset, and the locking member 500 will move from the second position 700 to the first position 600 along with the transmission member 300. This is beneficial to increasing the pressing force of the locking member 500 on the base 200, thereby being beneficial to improving the installation stability of the frame 100 on the base 200. When disassembling the installation bracket, first, an external force needs to be applied to the transmission member 300 (in this embodiment, taking applying pressure to the transmission member 300 as an example). Under the action of the external force, the transmission member 300 will move from the first position 600 to the second position 700. At the same time, the elastic member 400 will be in a compressed state after being stressed, and the locking member 500 will move from the first position 600 to the second position 700 together with the transmission member 300. After driving the transmission member 300 to move to the second position 700, a reverse screwing external force is applied to the transmission member 300. Under the action of the external force, the transmission member 300 will perform a reverse unlocking rotation relative to the frame 100. At the same time, the locking member 500 will rotate from the locked position 900 to the unlocked position 800 along with the transmission member 300. In the state of the unlocked position 800, the locking member 500 will disengage from the base 200, facilitating the removal of the frame 100 from the base 200, realizing the disassembly of the frame 100 from the base 200. In addition, after the locking member 500 rotates to the unlocked position 800, the external force applied to the transmission member 300 will be removed. When the external force disappears, the elastic member 400 will automatically reset, and the locking member 500 will move from the second position 700 to the first position 600 along with the transmission member 300.

[0058] The operation mode of the mounting bracket provided in this embodiment is simple, time-saving and labor-saving. The user does not need to use screws to fix the frame 100 on the base 200. Only by screwing the transmission member 300 can the frame 100 be detachably connected to the base 200. Moreover, the mounting bracket provided in this embodiment can achieve a lossless connection between the frame 100 and the base 200, avoiding punching damage to the frame 100 or the base 200.

[0059] In some embodiments, referring to Figures 2 to 6 , the frame 100 includes a connecting portion 110, and the transmission member 300 passes through the connecting portion 110. The transmission member 300 includes a first end portion 310 and a second end portion 320 located at both ends of the connecting portion 110. Among them, the locking member 500 is connected to the first end portion 310, and the second end portion 320 is provided with a driving structure 321, and the driving structure 321 is adapted to receive a driving force.

[0060] Specifically, in this embodiment, by way of example, for example, the driving structure 321 may be provided with a cross-shaped slot, and correspondingly, a cross screwdriver can be used to provide a driving force for the driving structure 321. In actual application, the cross screwdriver can be inserted into the cross-shaped slot of the driving structure 321, and then by screwing the cross screwdriver, the screwing operation of the transmission member 300 can be realized.

[0061] Or, in some other embodiments, by way of example, for example, the driving structure 321 may further include an operating handle, and the operating handle can be directly connected to the second end portion 320 of the transmission member 300. The operating handle can drive the transmission member 300 to rotate, and the volume of the operating handle can be designed to be very small to reduce the space volume occupied by the operating handle. In actual application, by screwing the operating handle, the screwing operation of the transmission member 300 can be realized.

[0062] Furthermore, compared with the operation mode of screwing the transmission member 300 with a cross screwdriver, the operation mode of screwing the transmission member 300 with an operating handle does not need to rely on a screwdriver to realize the screwing operation of the transmission member 300, which is beneficial to saving installation time and improving installation efficiency.

[0063] In some embodiments, referring to Figure 6 , a mounting groove 111 is recessed on one side of the connecting portion 110 facing the second end portion 320. The second end portion 320 passes through the mounting groove 111, and the elastic member 400 is disposed in the mounting groove 111. One end of the elastic member 400 is connected to the second end portion 320, and the other end of the elastic member 400 is connected to the bottom wall of the mounting groove 111. Among them, the size of the elastic member 400 is smaller than the size of the second end portion 320 to ensure that the elastic member 400 can be sleeved on the transmission member 300.

[0064] Specifically, in this embodiment, the connecting portion 110 is equivalent to providing a mounting housing for the transmission member 300 and the elastic member 400, and the transmission member 300 and the elastic member 400 are both arranged in the mounting groove 111, which is conducive to improving the integration level of the mounting bracket. When installing or removing the mounting bracket, it is necessary to apply an external force to the second end 320 of the transmission member 300. Under the action of the external force, the transmission member 300 will move from the first position 600 to the second position 700 in the mounting groove 111. At the same time, the elastic member 400 will be in a compressed state in the mounting groove 111 after being subjected to the force. The mounting groove 111 can limit the elastic member 400 to ensure that the elastic member 400 will not detach from the mounting bracket. After the external force disappears, the elastic member 400 has a tendency to restore elastic deformation, which will drive the transmission member 300 to move from the second position 700 to the first position 600 in the mounting groove 111.

[0065] In some embodiments, reference Figures 1 to 6 The frame 100 includes a shifting portion 120 extending in a direction parallel to the rotation axis. When the transmission member 300 is located at the first position 600, the shifting portion 120 is located within the movement path of the locking member 500 rotating around the rotation axis, thereby limiting the locking member 500 from rotating around the rotation axis from the unlocking position 800 to the locking position 900, or from the locking position 900 to the unlocking position 800. When the transmission member 300 is located at the second position 700, the shifting portion 120 is located outside the movement path of the locking member 500 rotating around the rotation axis.

[0066] Specifically, in order to ensure the installation stability of the frame 100 on the base 200 and prevent the frame 100 from being prone to shaking after being installed on the base 200, in this embodiment, a blocking portion 120 is protrudingly provided on the frame 100 (further, referring to the above embodiment, the blocking portion 120 can be provided on the connecting portion 110). When the transmission member 300 is located at the first position 600, that is, when the locking member 500 is also located at the first position 600, the blocking portion 120 will be within the movement path of the locking member 500 rotating around the rotation axis, that is, the blocking portion 120 can prevent the locking member 500 from rotating circumferentially around the rotation axis. At this time, even if the transmission member 300 is screwed, the locking member 500 will not rotate from the unlocking position 800 to the locking position 900, or from the locking position 900 to the unlocking position 800, thereby ensuring the installation stability of the frame 100 on the base 200. When the transmission member 300 is located at the second position 700, that is, when the locking member 500 is also located at the second position 700, the blocking portion 120 will be outside the movement path of the locking member 500 rotating around the rotation axis, that is, the blocking portion 120 cannot prevent the locking member 500 from rotating circumferentially around the rotation axis. At this time, when the transmission member 300 is screwed, the locking member 500 can rotate from the unlocking position 800 to the locking position 900, or from the locking position 900 to the unlocking position 800 outside the blocking portion 120 (exemplarily, for example, the locking member 500 can be above the blocking portion 120), thereby facilitating the installation or disassembly operation of the frame 100 on the base 200.

[0067] Further, by providing the blocking portion 120 on the frame 100, even if the transmission member 300 is accidentally touched, the locking member 500 will not rotate and shift, thus not affecting the fixing stability of the frame 100 on the base 200.

[0068] In some embodiments, referring to Figures 1 to 6 , the blocking portion 120 has a first side wall 121 and a second side wall 122 that are circumferentially arranged relative to each other along the rotation axis. When the locking member 500 abuts against the first side wall 121 and the transmission member 300 is at the first position 600, the locking member 500 is at the unlocking position 800. When the locking member 500 abuts against the second side wall 122 and the transmission member 300 is at the first position 600, the locking member 500 is at the locking position 900. Whether it is at the unlocking position 800 or at the locking position 900, under the drive of the elastic member 400, the transmission member 300 will be at the first position 600, and the locking member 500 will contact the side wall of the blocking portion 120. Only when installing or disassembling the frame 100, under the drive of an external force, the transmission member 300 will be at the second position 700, and the locking member 500 will not contact the side wall of the blocking portion 120.

[0069] In some embodiments, referring to Figures 1 to 6, a first side wall 121 is provided with a first guiding surface 1211, and a second side wall 122 is provided with a second guiding surface 1221. Along the direction from the first position 600 to the second position 700, the first guiding surface 1211 and the second guiding surface 1221 gradually approach each other.

[0070] Specifically, in order to prevent the locking member 500 from getting stuck on the gear position portion 120 during the process of rotating from the unlocking position 800 to the locking position 900 or from the locking position 900 to the unlocking position 800, in this embodiment, a first guiding surface 1211 is provided on the first side wall 121 that is in direct contact with the locking member 500, and a second guiding surface 1221 is provided on the second side wall 122 that is in direct contact with the locking member 500. The first guiding surface 1211 and the second guiding surface 1221 are inclined surfaces, and the first guiding surface 1211 and the second guiding surface 1221 play a guiding role when the locking member 500 moves between the first position 600 and the second position 700. When an external force is applied to the transmission member 300 to cause the locking member 500 to rotate from the unlocking position 800 to the locking position 900, the transmission member 300 will drive the locking member 500 to move from the first position 600 to the second position 700. During the above movement of the locking member 500, it will first slide along the first guiding surface 1211. Then, after the locking member 500 reaches the second position 700 (it can be sensed whether the locking member 500 has reached the second position 700 through the frictional resistance between the locking member 500 and the first guiding surface 1211), the transmission member 300 is screwed, so that the transmission member 300 drives the locking member 500 to rotate. The locking member 500 will rotate and gradually come into contact with the second guiding surface 1221. At this time, the external force is removed, and under the drive of the elastic member 400, the locking member 500 will slide along the second guiding surface 1221 and finally slide to the first position 600, realizing the abutment between the locking member 500 and the base 200. By providing the first guiding surface 1211 and the second guiding surface 1221, even if the transmission member 300 is screwed to a relatively small angle (exemplarily, for example, the transmission member 300 is screwed 90 degrees), the locking member 500 can still smoothly rotate from the unlocking position 800 to the locking position 900 without getting stuck on the gear position portion 120 during the rotation process.

[0071] Similarly, when an external force is applied to the transmission member 300 to cause the locking member 500 to rotate from the locking position 900 to the unlocking position 800, the transmission member 300 will drive the locking member 500 to move from the first position 600 to the second position 700. During the above movement of the locking member 500, it will first slide along the second guiding surface 1221, and then after the locking member 500 reaches the second position 700 (it can be sensed whether the locking member 500 has reached the second position 700 through the frictional resistance between the locking member 500 and the second guiding surface 1221), the transmission member 300 is screwed, so that the transmission member 300 drives the locking member 500 to rotate. The locking member 500 will rotate and gradually contact the first guiding surface 1211. At this time, the external force is removed, and under the drive of the elastic member 400, the locking member 500 will slide along the first guiding surface 1211 and finally slide to the first position 600, realizing the separation between the locking member 500 and the base 200. By providing the first guiding surface 1211 and the second guiding surface 1221, even if the transmission member 300 is screwed to a relatively small angle (exemplarily, for example, the transmission member 300 is screwed 90 degrees), the locking member 500 can still smoothly rotate from the locking position 900 to the unlocking position 800 without getting stuck on the gear position portion 120 during the rotation process.

[0072] In some embodiments, referring to Figures 1 to 6 , the transmission member 300 is provided with a limiting portion 330, and the frame 100 is provided with a guiding groove 130. The guiding groove 130 matches the movement track of the locking member 500. The limiting portion 330 is located in the guiding groove 130, and the limiting portion 330 can move along the guiding groove 130. Wherein, a limiting protrusion 131 is provided on one side of the guiding groove 130 close to the locking position 900, and the limiting portion 330 can be clamped on the limiting protrusion 131 to position the transmission member 300 at the locking position 900.

[0073] Specifically, after the frame 100 is installed on the base 200, due to the elastic force of the elastic member 400 acting on the locking member 500, the frame 100 will be clamped on the base 200. When the frame 100 is subjected to a pulling force, the elastic member 400 will be compressed or elongated, so that the locking member 500 can no longer clamp the frame 100 on the base 200, resulting in unstable installation of the frame 100. In this embodiment, as the locking member 500 rotates between the unlocking position 800 and the locking position 900, the limiting portion 330 can slide synchronously in the guiding groove 130. When the locking member 500 is located at the locking position 900, the limiting portion 330 will be clamped and fixed on the limiting protrusion 131, thereby solving the problem that the frame 100 will move outwards as a whole when subjected to a pulling force, resulting in unstable installation of the frame 100 on the base 200.

[0074] Further, the guiding groove 130 may include a first slideway 132, a second slideway 133, and a third slideway 134. The first slideway 132 is arranged along a direction parallel to the rotation axis, or the first slideway 132 may also extend along the first guiding surface 1211. The second slideway 133 is arranged along a direction perpendicular to the rotation axis. The third slideway 134 is arranged along a direction parallel to the rotation axis, or the third slideway 134 may also extend along the second guiding surface 1221. The second slideway 133 is connected to one end of the first slideway 132 close to the second position 700. The third slideway 134 is connected to the end of the second slideway 133 facing away from the first slideway 132, and the third slideway 134 and the first slideway 132 are arranged oppositely. During the process of the locking member 500 rotating from the unlocking position 800 to the locking position 900, the limiting portion 330 will first slide within the first slideway 132 (this process is the stage where the locking member 500 moves from the first position 600 to the second position 700), then slide within the second slideway 133 (this process is the stage where the locking member 500 rotates), and then slide within the third slideway 134 (this process is the stage where the locking member 500 moves from the second position 700 to the first position 600), and finally snap onto the limiting bump 131 to achieve stable positioning of the locking member 500. Similarly, during the process of the locking member 500 rotating from the locking position 900 to the unlocking position 800, the limiting portion 330 will first disengage from the limiting bump 131, then slide within the third slideway 134 (this process is the stage where the locking member 500 moves from the first position 600 to the second position 700), then slide within the second slideway 133 (this process is the stage where the locking member 500 rotates), and finally slide within the first slideway 132 (this process is the stage where the locking member 500 moves from the second position 700 to the first position 600).

[0075] In some embodiments, with reference to Figures 1 to 6 , the limiting bump 131 at least includes a first bump 1311 and a second bump 1312. The first bump 1311 and the second bump 1312 are arranged at intervals along a direction parallel to the rotation axis. The first bump 1311 and the second bump 1312 form three limiting grooves within the guiding groove 130. The limiting portion 330 is configured to be able to snap into the corresponding limiting groove according to the thickness of the base 200.

[0076] Specifically, in this embodiment, the first bump 1311 and the second bump 1312 will form three limiting grooves within the guiding groove 130. When the external force applied to the transmission member 300 disappears, under the drive of the elastic member 400 and according to the thickness of the base 200, the limiting portion 330 will snap into the corresponding limiting groove, enabling the locking member 500 to clamp bases 200 of different thicknesses and improving the versatility of the mounting bracket.

[0077] It should be noted that the spacing distance between the first bump 1311 and the second bump 1312 is designed in accordance with the thickness of the base 200. Therefore, the limiting portion 330 will be snapped into the corresponding limiting groove according to the thickness of the base 200.

[0078] In some embodiments, referring to Figures 1 to 6 , the first bump 1311 is disposed on the side of the second bump 1312 away from the gear portion 120. Along the direction from the locking position 900 to the unlocking position 800, the first bump 1311 protrudes beyond the second bump 1312, and the first bump 1311 is provided with a third guiding surface 1313, and the second bump 1312 is provided with a fourth guiding surface 1314. Among them, along the direction from the gear portion 120 to the guiding groove 130, the third guiding surface 1313 gradually approaches the guiding groove 130, and the fourth guiding surface 1314 gradually approaches the guiding groove 130.

[0079] Specifically, in order to facilitate the automatic engagement of the limiting portion 330 in the limiting groove, in this embodiment, when the limiting portion 330 moves to the limiting bump 131, it will contact the third guiding surface 1313 or the fourth guiding surface 1314. Since the third guiding surface 1313 and the fourth guiding surface 1314 are inclined, the end of the limiting bump 131 will provide a horizontal force for the limiting portion 330. Driven by the elastic member 400 and under the horizontal force, the limiting portion 330 will be more likely to be snapped into the limiting groove.

[0080] Furthermore, by way of example, for instance, when the thickness of the base 200 is relatively thin, driven by the elastic member 400, the limiting portion 330 will continuously slide in the third slideway 134 and finally be snapped into the relatively lower limiting groove. Since the limiting bump 131 is provided with a guiding surface, when the limiting portion 330 contacts the limiting bump 131, the guiding surface will provide a horizontal force, enabling the limiting portion 330 to be smoothly snapped into the corresponding limiting groove under the drive of the horizontal force, thereby realizing the positioning of the locking member 500. Similarly, when the thickness of the base 200 is relatively thick, driven by the elastic member 400, the limiting portion 330 will slide in the third slideway 134 and finally be snapped into the relatively upper limiting groove. Since the limiting bump 131 is provided with a guiding surface, when the limiting portion 330 contacts the limiting bump 131, the guiding surface will provide a horizontal force, enabling the limiting portion 330 to be smoothly snapped into the corresponding limiting groove under the drive of the horizontal force, thereby realizing the positioning of the locking member 500.

[0081] In some embodiments, referring to Figures 1 to 6The locking member 500 includes a first connection portion 510 and a second connection portion 520. The first connection portion 510 extends toward the transmission member 300 in a direction perpendicular to the rotation axis, and the second connection portion 520 is located at one end of the first connection portion 510 away from the transmission member 300 and extends toward the base in a direction parallel to the rotation axis. In other words, the overall structure of the locking member 500 is "L"-shaped, which is conducive to connecting the locking member 500 to the transmission member 300 and to facilitate the locking member 500 to abut against the base 200 as the transmission member 300 rotates.

[0082] In some embodiments, the locking member 500 is connected to the transmission member 300 by screws. Alternatively, the locking member 500 and the transmission member 300 are an integrally formed structure. Alternatively, the locking member 500 is welded to the transmission member 300.

[0083] Specifically, in this embodiment, the locking member 500 and the transmission member 300 are connected by screws, which is conducive to the installation, removal and replacement of the locking member 500. The locking member 500 and the transmission member 300 are connected by integral molding or welding, which is conducive to improving the connection stability between the locking member 500 and the transmission member 300.
