Description

Technical Field

[0001] The invention belongs to the technical field of battery detection, and in particular relates to a battery clamp fixing device. Background Art

[0002] As a device for fixing batteries and applying a certain pressure to the batteries, battery clamps are widely used in the battery testing process. Existing battery clamps clamp the batteries from both sides and apply stable pressure to the batteries from both sides through a series of methods.

[0003] Among them, the more conventional pressurizing fixture includes a fixture body, a clamping screw and a nut that cooperate with each other, and a pressurizing structure. The clamping screw runs through the fixture body, and the nut cooperates with the clamping screw from the other side of the fixture body. A pressurizing structure such as a spring is arranged between the head of the clamping screw and the fixture body. The battery is compressed by adjusting the distance between the head of the clamping screw and the fixture body to compress the pressurizing structure. In order to achieve precise control of the pressure, the clamping screw needs to be tightened with a torque wrench during manual pressurization. This results in the pressurization process being unable to be completed by one person alone. In actual operation, one person is often required to hold the fixture to prevent the fixture from moving, and the other person turns the torque wrench to tighten the clamping screw; this increases the labor cost required for battery testing and unnecessarily increases the manpower requirements of the testing process.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to solve one of the problems in the above-mentioned prior art and to provide a battery clamp fixing device, by which the clamp is fixed on the operating platform, without the need to specially assign one person to fix the battery clamp, thereby reducing the manpower requirements for battery testing and improving battery testing efficiency.

[0006] In order to achieve the above-mentioned object, the present invention provides a battery clamp fixing device, which is fixed on an operating platform, and includes a bottom wall, and a first limiting portion and a second limiting portion arranged perpendicular to the bottom wall, the first limiting portion and the second limiting portion are connected to the bottom wall, and the first limiting portion and the second limiting portion are arranged opposite to each other, and are used to limit the battery clamp from opposite sides;

[0007] It also includes a supporting portion arranged between the first limiting portion and the second limiting portion. The supporting portion avoids the clamping screw and is used to support the clamp body from the bottom so that the battery clamp is suspended on the bottom wall. The plane where the supporting portion is located intersects with the plane where the first limiting portion and the second limiting portion are located.

[0008] In the above scheme, the distance between the first limiting part and the second limiting part is adapted to the clamp body, and the battery clamp is fixed from both sides, thereby avoiding displacement of the battery clamp when tightening the clamping screw, so that the clamp pressurization process only requires one person to operate the torque wrench to tighten the clamping screw; the supporting part supports the clamp body, so that the battery clamp is suspended in the air, reserving space for the displacement of the clamp during the rotation of the clamp screw, and the clamp body will not be lifted up and tilted or offset, thereby improving the clamping effect.

[0009] Further, the supporting part is respectively arranged on the first limiting part and the second limiting part; or,

[0010] The supporting portion connects the first limiting portion and the second limiting portion.

[0011] Furthermore, the supporting portion divides the area between the first limiting portion and the second limiting portion into a first area and a second area located on both sides of the supporting portion, the clamp body is completely accommodated in the first area, and the second area is located between the supporting portion and the bottom wall.

[0012] In the above scheme, the first limiting part and the second limiting part can limit the clamp body as a whole, avoiding the situation where the part of the clamp body located below the battery remains stationary during partial limiting, while the part of the clamp body located above the battery is offset due to the inclination of the clamping screw, further improving the clamping effect and simplifying the pressurizing operation.

[0013] Furthermore, the battery clamp fixing device also includes a third limiting portion, which is respectively connected to the first limiting portion and the second limiting portion, and is arranged perpendicular to the first limiting portion, the second limiting portion and the bottom wall, and the third limiting portion is at least partially located in the first area.

[0014] In the above solution, the first limiting part, the second limiting part and the third limiting part block the battery clamp from three different directions respectively. When inserting the battery clamp, the technician does not need to deliberately align the clamp body with the first limiting part and the second limiting part, which improves the technician's usage experience.

[0015] Furthermore, the supporting portion is formed as a cantilever connected to the third limiting portion, and an escape area for escaping the clamping screw is formed between the first limiting portion and the second limiting portion.

[0016] When the supporting part is connected to the first limiting part and / or the second limiting part, the battery clamp can only be placed between the first limiting part and the second limiting part from above. On the one hand, it is not easy to align, and on the other hand, it is easy to cause harm to the technician when the battery clamp is not stable. In the above scheme, an avoidance area is formed between the supporting part and the first limiting part and the second limiting part, so that the battery clamp can be pushed between the first limiting part and the second limiting part from the direction opposite to the third limiting part, which further improves the user experience of the technician.

[0017] Furthermore, it also includes a first connecting part and a second connecting part, which are connected to the bottom wall and are arranged on the same side as the first limiting part and the second limiting part, and are respectively fitted with the first limiting part and the second limiting part from the side opposite to the first limiting part and the second limiting part, and the first limiting part and the second limiting part are detachably connected to the bottom wall through the first connecting part and the second connecting part, respectively.

[0018] In the above scheme, the detachable connection method makes it easy for technicians to maintain and replace the battery clamp fixing device, and the battery clamp fixing device can be adjusted according to the actual shape and structure of the battery clamp, thereby improving the user experience.

[0019] Furthermore, the first limiting portion and the second limiting portion have a first connecting hole extending therethrough, and the first connecting portion and the second connecting portion have a corresponding second connecting hole;

[0020] The battery clamp fixing device also includes a connecting piece, and when the first connecting portion is aligned with the first limiting portion and / or the second connecting portion is aligned with the second limiting portion, the first connecting hole is aligned with the second connecting hole, and the connecting piece passes through the first connecting hole and the second connecting hole.

[0021] Furthermore, the battery clamp fixing device also includes a locking member for adjusting the friction between the first connecting portion and the first limiting portion and / or between the second connecting portion and the second limiting portion.

[0022] In the above scheme, technicians can selectively adjust the matching angles of the first limiting part, the second limiting part, the first connecting part and the second connecting part according to operating habits or the size of the operating space, and then adjust the operating angle for pressurizing the battery clamp, further improving the technician's user experience.

[0023] Furthermore, the first connecting hole is located on the midline of the first limiting portion and / or the second limiting portion perpendicular to the third limiting portion, and the distance from the axis of the first connecting hole to the side of the third limiting portion away from the supporting portion is the same as half of the width of the first limiting portion and / or the second limiting portion in the direction perpendicular to the midline.

[0024] In the above scheme, by adjusting the position of the first connecting hole, the battery clamp fixing device not only has a first state in which the first limiting portion, the second limiting portion and the third limiting portion are perpendicular to the bottom wall, but also has a second state in which the third limiting portion is parallel to the bottom wall. In the second state, the third limiting portion is in contact with the bottom wall, so that the second state has higher stability.

[0025] Furthermore, the second connecting hole is configured as a strip-shaped through hole extending in a direction perpendicular to the bottom wall, and the connecting member is slidably disposed relative to the strip-shaped through hole along the extending direction of the strip-shaped through hole.

[0026] In the above scheme, when the technician adjusts the matching angle between the first limiting part, the second limiting part and the first connecting part and the second connecting part, there is no need to disassemble and reinstall. It is only necessary to adjust the locking part to reduce the friction between the limiting part and the connecting part, and then increase the friction between the two through the locking part after adjusting to the required angle to achieve locking. This further simplifies the adjustment process and improves the user experience of the technician.

[0027] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0028] 1. The first limiting part and the second limiting part limit the movement of the battery clamp from both sides. At this time, only one person is needed to complete the pressurization operation of the clamp; the battery clamp is lifted up by the supporting part so that it is in a suspended state, and a gap is formed between the end of the clamping screw and the bottom wall, which reserves space for the displacement of the clamping screw, avoids the clamping screw from abutting against the bottom wall and lifting the clamp body during the clamping process, thereby improving the pressurization stability.

[0029] 2. The third limiting portion is connected to the first limiting portion and the second limiting portion to limit the installation of the battery clamp. The supporting portion is connected to the third limiting portion and forms an avoidance area between the first limiting portion and the second limiting portion, so that the battery clamp can be horizontally placed in the battery clamp fixing device under the guidance of the supporting portion, thereby improving the user experience of the technicians.

[0030] 3. The first limiting part is detachably connected to the first connecting part, and the second limiting part is detachably connected to the second connecting part. The technicians can not only replace the parts where the first limiting part and the second limiting part are located according to actual needs, but also connect the first limiting part and the second limiting part to the first connecting part and the second connecting part at different angles according to operational needs, thereby adjusting the angle between the supporting part and the horizontal plane, thereby improving the use flexibility of the battery clamp fixing device.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0040] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In the description of the present invention, unless otherwise specified, the term "A and / or B" is generally understood, and its meaning includes: only A, only B, and the existence of A and B at the same time.

[0043] The present invention provides a battery clamp fixing device, which is fixed on an operating platform. Figures 1 to 7As shown, it includes a bottom wall 3, and a first limiting portion 1 and a second limiting portion 2 arranged perpendicular to the bottom wall 3. The first limiting portion 1 and the second limiting portion 2 are connected to the bottom wall 3 and are arranged opposite to each other, and are used to limit the battery clamp from opposite sides;

[0044] It also includes a supporting portion 4 arranged between the first limiting portion 1 and the second limiting portion 2. The supporting portion 4 is arranged to avoid the clamping screw 7 and is used to support the clamp body 6 from the bottom so that the battery clamp is suspended on the bottom wall 3. The plane where the supporting portion 4 is located intersects with the plane where the first limiting portion 1 and the second limiting portion 2 are located.

[0045] When the battery clamp clamps the battery 9, the clamp body 6 clamps the battery 9 from both sides of the battery 9 respectively, the clamp body 6 passes through the edge of the clamp body 6, the pressurizing structure 8 is elastic and is located between the head of the pressurizing screw 7 and the clamp body 6, and the nut cooperates with the pressurizing screw 7 from the other side of the clamp body 6; the compression degree of the pressurizing structure 8 is controlled by adjusting the distance between the head of the pressurizing screw 7 and the clamp body 6, and the rebound force provided by the pressurizing structure 8 acts on the clamp body 6 to achieve pressurization of the battery 9.

[0046] The battery clamp fixing device and the operating platform 10 remain relatively still. When the battery clamp needs to be pressurized, the technician first places the clamp between the first limiting portion 1 and the second limiting portion 2. At this time, the bottom of the clamp body 6 is against the supporting portion 4, so that the entire battery clamp is suspended, that is, the clamp body 6 and the clamping screw 7 are not in contact with the bottom wall 3; then, the clamping screw 7 is tightened by a torque wrench to achieve pressurization; in the process of tightening the clamping screw 7, the first limiting portion 1 and the second limiting portion 2 limit the clamp body 6 from both sides of the clamp body 6 respectively, avoiding the movement of the clamp, and then only one person is needed to complete the clamp pressurization operation. The state of the battery clamp fixed in the battery clamp fixing device is shown in FIG. Figure 1 As shown, in Figure 1 In the figure, a nut (not shown) cooperating with the clamping screw 7 is hidden inside the lower part of the clamp body 6. In other embodiments, the nut can also be set independently of the clamp body 6.

[0047] Since the clamp body 6 and the clamping screw 7 are both in a suspended state, a space is reserved between the bottom wall 3 and the clamping screw 7 for the clamping screw 7 to extend out, thereby preventing the clamp body 6 from tilting and misaligning due to the clamping screw 7 abutting against the bottom wall 3 during tightening.

[0048] As an embodiment of the present invention, the battery clamp fixing device is fixedly connected to the operating platform 10 through the bottom wall 3, such as Figure 2 and Figure 3As shown, the lower surface of the operating platform 10 is a plane, and the bottom wall 3 also includes a first extension portion 301 extending downward from one end close to the edge of the operating platform 10, and a second extension portion 302 bent from the end of the first extension portion 301 in a direction parallel to the bottom wall 3, forming a "U"-shaped bending structure that accommodates the edge of the platform, and a first retractable fixing member 303 perpendicular to the operating platform 10 and arranged on the second extension portion 302 is used to lock the battery clamp fixing device with the operating platform 10 from the lower surface of the operating platform 10, so that the bottom wall 3 is close to the upper surface of the operating platform 10, thereby fixing the battery clamp fixing device; technical personnel in this field can also adjust the fixing method according to the shape of the operating platform 10.

[0049] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0050] Embodiment 1

[0051] As an embodiment of the present invention, this embodiment provides a battery clamp fixing device. In this embodiment, the first limiting portion 1 and the second limiting portion 2 have the same shape and size, are arranged perpendicular to the bottom wall 3, and the first limiting portion 1 and the second limiting portion 2 are parallel to each other. The supporting portion 4 is respectively arranged on the opposite sides of the first limiting portion 1 and the second limiting portion 2, and extends outward to form.

[0052] Specifically, Figure 5 As shown, the first limiting portion 1 and the second limiting portion 2 are fixedly connected to the bottom wall 3, and the spacing between the first limiting portion 1 and the second limiting portion 2 matches the size of the clamp body 6, so that after the battery clamp is placed, the two sides of the clamp body 6 are respectively abutted against the first limiting portion 1 and the second limiting portion 2, and then the battery clamp is limited by the first limiting portion 1 and the second limiting portion 2; the supporting portion 4 includes: the first limiting portion 1 extends toward one side of the second limiting portion 2 in a direction close to the second limiting portion 2 to form two first supporting portions arranged at intervals, and the first supporting portion is perpendicular to the first limiting portion 1; the second limiting portion 2 has two second supporting portions protruding in a direction close to the first limiting portion 1, and the projection shape of the first supporting portion and the second supporting portion on the first limiting portion 1 and the second limiting portion 2 is a rectangle, forming a cantilever obtained by horizontally extending the projection shape, and the second supporting portion is opposite to the first supporting portion and is located in the same horizontal plane, forming a supporting surface for horizontally supporting the clamp body 6, so as to achieve stable support for the battery clamp.

[0053] In other embodiments, the supporting portion 4 may not be arranged horizontally, and only needs to intersect with the plane where the first limiting portion 1 and the second limiting portion 2 are located, and can be adjusted according to actual usage requirements.

[0054] Furthermore, the distance between the two first supporting parts on the first limiting part 1 is smaller than the distance between the two clamping screws 7 on the side of the clamp body 6 close to the first limiting part 1. Correspondingly, the distance between the two second supporting parts on the second limiting part 2 is smaller than the distance between the two clamping screws 7 on the side of the clamp body 6 close to the second limiting part 2, thereby achieving stable support for the clamp body 6; improving the fixing effect of the battery clamp fixing device on the battery clamp; and by fully fixing the battery clamp, pressurization of the battery clamp can be achieved by only one person.

[0055] The plane where the supporting portion 4 is located divides the area between the first limiting portion 1 and the second limiting portion 2 into a first area away from the bottom wall 3 and a second area close to the bottom wall 3. After the battery clamp is placed in the battery clamp fixing device, the clamp body 6 is located in the first area, and the clamp body 6 is vertically penetrated by the clamp body 6, so that the head of the clamping screw 7 protrudes from the upper surface of the clamp body 6; the distance between the supporting portion 4 and the bottom wall 3 is greater than the length of the clamping screw 7 that extends outward from the bottom of the clamp body 6 in the battery clamp, so that the battery clamp as a whole is suspended above the bottom wall 3 in the supporting state.

[0056] In order to further improve the limiting effect on the clamp body 6, the height of the first limiting portion 1 and the second limiting portion 2 in the first area is greater than or equal to the thickness of the clamp body 6 in the clamping state, effectively avoiding the misalignment of the clamp body 6.

[0057] In other embodiments, the number of the first supporting part and the second supporting part can be independently increased or decreased according to actual needs, and the height of the supporting part 4 and the angle with the horizontal plane can be adjusted according to actual operation requirements; the cross-sectional shape of the first supporting part and the second supporting part can also be adjusted according to actual usage requirements.

[0058] Embodiment 2

[0059] As another embodiment of the present invention, this embodiment differs from the first embodiment in that the structure of the supporting portion 4 is different.

[0060] In this embodiment, if Figure 6 As shown, the supporting portion 4 is horizontally arranged, and its two ends are respectively connected to the first limiting portion 1 and the second limiting portion 2, that is, the first limiting portion 1, the second limiting portion 2 and the supporting portion 4 form an I-shaped structure, which further improves the structural stability and supporting stability of the battery clamp fixing device.

[0061] Furthermore, the width of the supporting portion 4 in a direction parallel to the first limiting portion 1 and the second limiting portion 2 is smaller than the distance between two adjacent clamping screws 7 in the battery clamp, thereby achieving avoidance of the clamping screws 7; in other embodiments, the supporting portion 4 is the same width as the first limiting portion 1 and the second limiting portion 2, and a plurality of avoidance holes are provided on the supporting portion 4. When the battery clamp is installed in place, the clamping screw 7 is aligned with the avoidance hole and passes through the avoidance hole. At this time, the avoidance hole not only has an avoidance function, but also achieves the limitation of the clamping screw 7, which is more conducive to the stable implementation of the clamp pressurization operation.

[0062] Embodiment 3

[0063] As another embodiment of the present invention, this embodiment provides a battery clamp fixing device. In this embodiment, in addition to the first limiting portion 1 and the second limiting portion 2, it also includes a third limiting portion 5. The third limiting portion 5 is perpendicular to the first limiting portion 1 and the second limiting portion 2, and its two ends are respectively connected to the first limiting portion 1 and the second limiting portion 2, and the first limiting portion 1, the second limiting portion 2 and the third limiting portion 5 are all perpendicular to the bottom wall 3, and the supporting portion 4 is connected to the third limiting portion 5.

[0064] Specifically, Figure 7 As shown, the first limiting portion 1, the second limiting portion 2 and the third limiting portion 5 are all fixedly connected to the bottom wall 3, and the supporting portion 4 is horizontally extended outward from the surface of the third limiting portion 5, and is arranged perpendicular to the first limiting portion 1, the second limiting portion 2 and the third limiting portion 5 to form a supporting surface for horizontally supporting the battery clamp; and a gap is formed between the supporting portion 4 and the first limiting portion 1 and the second limiting portion 2, which serves as an avoidance area for avoiding the tightening screws 7 on the battery clamp.

[0065] Compared with the first embodiment, this scheme further enriches the way for technicians to place the battery clamp into the battery clamp fixing device. In the first and second embodiments, due to the obstruction of the supporting portion 4, the battery clamp can only be placed into the battery clamp fixing device from top to bottom. Since the size adaptability of the battery clamp fixing device and the battery clamp is relatively high, this placement method is not easy to align, and the battery clamp may slip out of the hand due to unstable grip, causing harm to the technician. In the present embodiment, an avoidance structure is formed between the supporting portion 4 and the first limit portion 1 and the second limit portion 2. The technician can push the battery clamp horizontally into the battery clamp fixing device along the extension direction of the supporting portion 4. The supporting portion 4 can guide the installation of the battery clamp, and the battery clamp and the battery clamp fixing device are easier to align. In the process of placing the battery clamp into the battery clamp fixing device, the clamp body 6 is placed on the supporting portion 4 to share the weight of the battery clamp, avoid the occurrence of unstable grip, and improve operational safety.

[0066] Furthermore, the supporting portion 4 divides the area between the first limiting portion 1 and the second limiting portion 2 into a first area away from the bottom wall 3 and a second area close to the bottom wall 3, and the third limiting portion 5 is formed as a side wall of the first area and is flush with the height of the first limiting portion 1 and the second limiting portion 2; when the battery clamp is placed in the battery clamp fixing device, the clamp body 6 enters the first area under the guidance of the first limiting portion 1, the second limiting portion 2 and the supporting portion 4, and is installed in place when abutting against the third limiting portion 5, without the need for alignment operation; the distance between the supporting portion 4 and the bottom wall 3 is greater than the length of the clamping screw 7 extending outward from the bottom of the clamp body 6 in the battery clamp, so that the battery clamp as a whole is suspended above the bottom wall 3 in the supporting state; when the technician performs the pressurization operation independently, the clamping screw 7 can be conveniently tightened from the top, and since there is a gap between the end of the clamping screw 7 and the bottom wall 3, the clamp body 6 will not be lifted up due to the tightening of the clamping screw 7.

[0067] In order to further improve the limiting effect on the clamp body 6, the height of the first limiting portion 1 and the second limiting portion 2 in the first area is greater than or equal to the thickness of the clamp body 6 in the clamping state, effectively avoiding the misalignment of the clamp body 6.

[0068] In other embodiments, the cross-sectional shape of the supporting portion 4 can be adjusted according to actual use requirements. For battery clamps of different shapes, the shape of the projection of the supporting portion 4 on the bottom wall 3 can also be set to a "Y" shape, an "O" shape, etc. Conventional replacements and improvements to the morphology of the supporting portion 4 also fall within the protection scope of the present invention.

[0069] Embodiment 4

[0070] As another embodiment of the present invention, this embodiment further makes the following improvements on the basis of the third embodiment.

[0071] In this embodiment, if Figure 7 As shown, a first connection portion 304 and a second connection portion 305 are further provided on the bottom wall 3, and the first connection portion 304 and the second connection portion 305 are fixedly connected to the bottom wall 3, and are extended outwardly from the connection point in a direction perpendicular to the bottom wall 3, and the first connection portion 304 and the second connection portion 305 are respectively fitted with the first limiting portion 1 and the second limiting portion 2 from the side opposite to the first limiting portion 1 and the second limiting portion 2, and the first limiting portion 1 and the second limiting portion 2 are respectively detachably connected to the first connection portion 304 and the second connection portion 305; specifically, a first connection hole is provided on the first limiting portion 1 and the second limiting portion 2, and a second connection hole is correspondingly provided on the first connecting portion 304 and the second connecting portion 305, and after the first connecting hole and the second connecting hole are aligned, the first connecting hole and the second connecting hole are penetrated by a connecting member to realize the connection between the first limiting portion 1 and the first connecting portion 304, and the second limiting portion 2 and the second connecting portion 305.

[0072] In the above scheme, the first limiting portion 1, the second limiting portion 2, the third limiting portion 5 and the supporting portion 4 are regarded as a whole to achieve a detachable connection with the bottom wall 3, so that technicians can adapt the corresponding battery clamp fixing device according to different battery clamps, and can more easily maintain and repair the battery clamp fixing device, further improving the user experience; in addition, technicians can adjust and fix the angle between the supporting portion 4 and the horizontal plane by disassembly and reconnection as needed, so as to clamp the battery clamp at different angles.

[0073] In order to achieve the parking between the first limiting part 1 and the first connecting part 304, and between the second limiting part 2 and the second connecting part 305, the battery clamp fixing device also includes a locking piece. In this embodiment, a connecting screw and a nut cooperating with the connecting screw are used as a connecting piece, which also has the function of a locking piece. On the one hand, the fixation can be better achieved through the cooperation of the connecting screw and the nut. On the other hand, by adjusting the position of the nut on the connecting screw, the friction between the first connecting part 304 and the first limiting part 1 and between the second limiting part 2 and the second connecting part 305 is increased or decreased, so that the parking can be achieved more easily.

[0074] In other embodiments, the connecting member and the locking member may also be provided as two independent parts to respectively realize the connecting and locking functions.

[0075] In order to facilitate operation and avoid obstruction to the battery clamp, the head of the connecting screw is located between the first limiting portion 1 and the second limiting portion 2, and the nut cooperates with the connecting screw from the side opposite to the first connecting portion 304 and the second connecting portion 305.

[0076] In other embodiments, the locking member may also be provided as a protrusion and a groove on the side opposite to the first connection portion 304 and the first limiting portion 1 and / or on the side opposite to the second connection portion 305 and the second limiting portion 2 .

[0077] Normally, the supporting portion 4 is arranged horizontally or vertically for the convenience of operation by technicians, but in the vertical state, stable parking cannot be achieved only by the locking member. For this reason, the technician adjusts the position of the first connecting hole, and the first limiting portion 1 and the second limiting portion 2 have a center line perpendicular to the third limiting portion 5, the first connecting hole is located on the center line, and the distance from the first connecting hole to the side of the third limiting portion 5 away from the supporting portion 4 is the same as half of the width of the first limiting portion 1 and the second limiting portion 2 in the perpendicular direction of the center line; when the supporting portion 4 is vertical, the third limiting portion 5 abuts against the bottom wall 3, which can cooperate with the locking member to achieve more stable parking.

[0078] Furthermore, since the connecting member is configured as a connecting screw and a nut, and taking into account possible damage caused by repeated disassembly, the second connecting hole on the first connecting portion 304 and the second connecting portion 305 is configured as a strip through hole, that is, the connecting member is slidably arranged relative to the first connecting portion 304 and the second connecting portion 305 along the length direction of the strip through hole. When adjusting the angle between the supporting portion 4 and the bottom wall 3, there is no need to repeatedly disassemble the connecting screw and the nut, but only the position of the nut on the connecting screw needs to be adjusted.

[0079] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form.
