Description

Technical Field

[0001] The present invention belongs to the technical field of support hangers, and particularly relates to an adjustable-angle support hanger for power equipment. Background Art

[0002] Support hangers are the collective name of brackets and hangers, which play functions such as bearing the weight of each fitting and its medium, restricting and limiting the unreasonable displacement of building components, and controlling the vibration of components in each construction link, and play an extremely important role in the safe operation of building facilities. Support hangers are mainly used in electromechanical engineering facilities such as building water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, communication, etc. During the ceiling installation process of indoor power equipment, support hangers need to be used in cooperation with the installation of power equipment, so as to install the power equipment at the corresponding position through the support hangers;

[0003] At the same time, after retrieving existing public documents, a patent document with the patent number CN209762665U discloses a projector hanger for adjusting the angle by rotating the bracket. The first bracket is relatively fixed to the boom device. The first bracket is provided with a first side plate, and the second bracket is provided with a second side plate. A first hinge point is provided between the first side plate and the second side plate. The first side plate and the second side plate are hinged to each other through the first hinge point. A first long circular hole is provided on the first side plate or the second side plate. The first side plate and the second side plate can rotate relative to each other, and the threaded connecting piece can pass through the first long circular hole and fix the relative positions of the first side plate and the second side plate at any position within the first long circular hole. Beneficial effects: The first bracket and the second bracket are hinged to each other to realize the angle adjustment of the projector, and the projection angle of the projector is locked through the first long circular hole, so that the projector hanger can realize rapid angle adjustment. The structure of the rotating bracket in this technical solution is simple and compact, and the appearance is concise. The present invention relates to a suspended projector hanger.

[0004] However, when the existing support hangers are in use, since they are installed on the wall top surface, after installing with electronic equipment, due to the different weights of different electronic equipment, after installing the electronic equipment and the support hanger, adjusting its angle will affect the adjustment efficiency. Therefore, the angle adjustment of the support hanger is mostly carried out before installation. The existing adjustment method is to implement horizontal adjustment and vertical adjustment separately. Thus, different limiting structures will be used to limit this adjustment method, and this method will cause the horizontal adjustment and vertical adjustment work to not be positioned immediately, and there will be a situation where the adjustment angle is self-deviated due to too many operating procedures. Summary of the Invention

[0005] The object of the present invention is to provide an adjustable-angle support hanger for electrical equipment. By moving the sleeve to synchronously drive the positioning tooth plate and the limit rack to move upward, the adjustment operation of the front and back processes of the flat cylinder or the semi-circular rack can be directly controlled, solving the problem that the flat adjustment and longitudinal adjustment work cannot be positioned immediately, and there will be too many operation processes resulting in self-deviation of the adjustment angle.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] An adjustable-angle support hanger for electrical equipment includes a locking assembly, including a locking plate bolted to the wall top surface; a suspension assembly, including an installation cylinder fixed to the lower end surface of the locking plate; a flat adjustment assembly, including a flat cylinder coaxially docked with the lower end of the installation cylinder and a rotating cylinder fixed to the upper end surface of the flat cylinder and rotating in the inner cavity of the installation cylinder; a three-dimensional adjustment assembly, including a semi-circular rack arranged inside the flat cylinder; a hoisting assembly, including a hoisting plate located directly below the flat cylinder and L-shaped plates located at the four diagonal positions of the hoisting plate; an extended installation assembly for telescoping the L-shaped plates is arranged inside a groove opened at the lower end of the hoisting plate; a linkage positioning assembly, including a moving sleeve sleeved on the installation cylinder and located at the annular groove position; a rotating assembly, including a linkage bevel gear block arranged in a linkage groove on the inner wall of the flat cylinder.

[0008] Further, an angle tooth plate meshing with the semi-circular rack is arranged in the middle inside the semi-circular rack, a positioning tooth plate with clearance fit is arranged inside the installation cylinder, an annular groove is opened on the outer wall of the installation cylinder, the inside of the rotating cylinder and the flat cylinder are connected, a conical ring gear block fixed to the upper end surface of the rotating cylinder meshes with the linkage bevel gear block, a limit rack inside the flat cylinder meshes with the outside of the semi-circular rack, the extended installation assembly includes an extension plate located in the middle of the upper end of the hoisting plate and a linkage plate located inside the groove, and the lower end surface of the linkage plate is flush with the lower end surface of the hoisting plate. Four linkage bars are fixedly arranged in a circumferential and uniformly distributed manner along the axial direction on the circumferential wall surface of the linkage plate, and a bidirectional shaft bar flush with the lower end surface of the linkage plate is arranged on the lower surface of each linkage bar.

[0009] Further, square openings communicating with the inside of the groove are opened at the four corner parts of the extension plate, a travel bar fixed to the vertical end surface of the L-shaped plate slides through the inside of the square opening, and the lower end surface of the travel bar is flush with the lower end surface of the hoisting plate. The shaft bar fixed to the end surface of the travel bar away from the L-shaped plate and the shaft bar fixed to the end surface of the linkage bar away from the linkage plate are rotationally matched with the two ends of the adjacent bidirectional shaft bar at the shaft hole positions. The shaft bar fixed between the extension plate and the linkage plate is rotationally matched with the hoisting plate through a bearing. Through the cooperation of the extension plate and the linkage plate, the travel bar is pushed to expand and contract, synchronously driving multiple L-shaped plates to perform expansion and contraction work.

[0010] Further, two groups of guide cylinders arranged in a circumferential and annular pattern are fixed to the circumferential wall of the planar cylinder along the axial direction. Both ends of the semi-circular rack passing through the corresponding guide cylinder positions are bolted to the upper end surface of the lifting plate. Both ends of the semi-circular rack pass through the inside of the guide cylinder, and the guide cylinder limits the semi-circular rack, enabling the semi-circular rack to slide along the internal path of the guide cylinder when being driven to rotate.

[0011] Further, a plurality of vertical ports communicating with the inside of the annular groove are provided on the surface of the installation cylinder. A sliding plate is arranged inside the installation cylinder directly above the positioning tooth plate. The shaft rod fixed between the sliding plate and the moving sleeve passes through the inside of the vertical port. The shaft rod between the sliding plate and the moving sleeve is located in the vertical port, which can limit the moving sleeve and the sliding plate, ensuring that the moving sleeve and the sliding plate do not rotate and can move synchronously.

[0012] Further, the spring fixed to the upper end surface of the sliding plate abuts against the inner top surface of the installation cylinder. The sliding plate, the positioning tooth plate, and the limiting rack are sequentially fixed from top to bottom through the provided connecting rod. When the sliding plate moves, it will drive the positioning tooth plate and the limiting rack to move synchronously through the connecting rod, making the moving distances of the positioning tooth plate and the limiting rack the same. Thus, when the sliding plate is released, the positioning tooth plate and the limiting rack can reset to their initial positions at the same time.

[0013] Further, a positioning tooth opening meshing with the positioning tooth plate is provided in the middle position of the upper end surface of the conical ring gear block. A central plate connected to the inner bottom surface of the installation cylinder is fixed to the outer wall of the rotating cylinder. An annular rail groove is provided on the inner bottom surface of the installation cylinder. A plurality of ball openings provided on the lower end surface of the central plate are each internally embedded with a ball block cooperating with the annular rail groove. Through the setting of the central plate, the central plate is used to support the conical ring gear block, enabling the conical ring gear block to stably cooperate and mesh with the linkage bevel gear block. By the annular rail groove absorbing the ball blocks, the central plate will not rotate and shift in the installation cylinder.

[0014] Further, a rotating block is fixed to the end face of the shaft rod of the linkage bevel gear block rotatably fitted with the installation cylinder through a bearing. A longitudinal plate is fixed to the end face of the shaft rod of the angle tooth plate rotatably fitted with the planar cylinder through a bearing. By using the rotating block and the longitudinal plate, the rotation of the linkage bevel gear block and the angle tooth plate can be facilitated.

[0015] Further, four adjustment ports respectively communicating with the inside of the square port are provided on the upper end surface of the lifting plate. A T-shaped block slidably fitted with the adjustment port is fixed to the upper surface of the travel bar away from the end of the L-shaped plate. Since the T-shaped block slides in the adjustment port and the horizontal part of the T-shaped block is located above the lifting plate, the T-shaped block cannot pass completely through the adjustment port.

[0016] Furthermore, calibration shafts are fixed at positions on two opposite inner faces of each square opening near the L-shaped plate. Travel ports are provided on the sides of the travel bar corresponding to the calibration shafts, and each calibration shaft slides in the travel port. By inserting the calibration shaft into the travel port, the calibration shaft can limit the travel bar, enabling the travel bar to slide stably in the travel port.

[0017] The present invention has the following beneficial effects:

[0018] In the present invention, by setting the moving sleeve to synchronously drive the positioning tooth plate and the limit rack to move upward, the operation of the front and back processes of the flat cylinder or the semi-circular rack can be directly controlled. After the angle adjustment is completed, the moving sleeve can be loosened, and then the positioning tooth plate and the limit rack can limit the flat cylinder and the semi-circular rack in the first time. When the work can be adjusted comprehensively at multiple angles, the stability between the structures can be ensured in the first time, avoiding the situation of angle deviation caused by too many operation processes. By controlling the moving sleeve to move upward inside the annular groove along the position of the mounting cylinder, the moving sleeve will drive the positioning tooth plate and the limit rack to move upward accordingly, so that the positioning tooth plate is disengaged from the meshing relationship with the conical ring gear block, and the limit rack is disengaged from the meshing relationship with the semi-circular rack. At this time, the flat cylinder can be controlled to rotate. Therefore, the flat cylinder will drive the lifting plate to rotate in a plane through the semi-circular rack. At the same time, the angle tooth plate is controlled to rotate. Thus, the angle tooth plate will drive the semi-circular rack to rotate inside the flat cylinder, and drive the lifting plate to tilt at an angle with respect to the flat cylinder.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 9 . The present invention is an adjustable-angle power equipment support hanger. By synchronously driving the positioning tooth plate 702 and the limit rack 704 to move upward through the moving sleeve 701, the operation of the front and back processes of the flat cylinder 301 or the semi-circular rack 401 can be directly controlled. After the angle adjustment is completed, the moving sleeve 701 can be loosened, and then the positioning tooth plate 702 and the limit rack 704 can limit the flat cylinder 301 and the semi-circular rack 401 immediately. While realizing multi-angle comprehensive adjustment work, it can also ensure the stability between structures in a timely manner and avoid the situation of angle deviation caused by too many operation processes.

[0041] Specifically, the locking assembly 1 includes a locking plate 101 bolted to the wall top surface. The suspension assembly 2 includes an installation cylinder 201 fixed to the lower end surface of the locking plate 101. The planar adjustment assembly 3 includes a flat cylinder 301 coaxially connected to the lower end of the installation cylinder 201 and a rotating cylinder 302 fixed to the upper end surface of the flat cylinder 301 and rotating in the inner cavity of the installation cylinder 201. The three-dimensional adjustment assembly 4 includes a semi-circular rack 401 arranged inside the flat cylinder 301 and an angle tooth plate 402 located in the middle position inside the semi-circular rack 401 and meshing with it. The linkage positioning assembly 7 includes a moving sleeve 701 sleeved on the installation cylinder 201 and located at the position of the annular groove 2011, a positioning tooth plate 702 located inside the installation cylinder 201, and a limit rack 704 located inside the flat cylinder 301 and meshing with the outer side of the semi-circular rack 401. The rotating assembly 8 includes a linkage bevel gear block 801 arranged in the linkage groove 2012 on the inner wall of the flat cylinder 301. The number of teeth on the used semi-circular rack 401 and the positioning tooth plate 702 can meet the required adjustment work, so that the rotation amplitude of the flat cylinder 301 and the rotation amplitude of the semi-circular rack 401 can be more accurate;

[0042] When the above structure is set and used, when performing angular rotation, the moving sleeve 701 is controlled to move upward inside the annular groove 2011 along the position of the mounting cylinder 201. Thus, the moving sleeve 701 will drive the positioning tooth plate 702 and the limit rack 704 to move upward accordingly, so as to disengage the positioning tooth plate 702 from the tapered ring gear block 304 and the limit rack 704 from the semi-circular rack 401. At this time, the planar cylinder 301 can be controlled to rotate. Therefore, the planar cylinder 301 will drive the hoisting plate 501 to perform planar rotation through the semi-circular rack 401. At the same time, the angular tooth plate 402 is controlled to rotate. Thus, the angular tooth plate 402 will drive the semi-circular rack 401 to rotate inside the planar cylinder 301, and thereby drive the hoisting plate 501 to be angularly inclined with respect to the planar cylinder 301. Through the above operations, the work of comprehensively adjusting the hoisting plate 501 at multiple angles can be realized.

[0043] Further, according to Figure 7 and Figure 8 it can be known that an annular groove 2011 is formed on the outer wall of the mounting cylinder 201, the rotary cylinder 302 is communicated with the inside of the planar cylinder 301, and the tapered ring gear block 304 fixed on the upper end surface of the rotary cylinder 302 is engaged with the linkage bevel gear block 801. Through controlling the meshing cooperation between the tapered ring gear block 304 and the linkage bevel gear block 801, when the linkage bevel gear block 801 rotates, it can directly drive the tapered ring gear block 304 to rotate. At the same time, the linkage bevel gear block 801 will rotate in the annular groove 2011, so as to reduce the excessive occupation of the inner cavity space of the mounting cylinder 201 by the linkage bevel gear block 801 and make the tapered ring gear block 304 coaxial with the inner cavity of the mounting cylinder 201.

[0044] Further, according to Figure 8 and Figure 9 it can be known that two groups of annularly and evenly distributed guide cylinders 3011 are fixed on the circumferential wall surface of the planar cylinder 301 along the axial direction. Both ends of the semi-circular rack 401 passing through the corresponding guide cylinders 3011 are bolted to the upper end surface of the hoisting plate 501. The guide cylinders 3011 are communicated with the inside of the planar cylinder 301. Therefore, when the semi-circular rack 401 is driven to rotate, the semi-circular rack 401 will slide inside the guide cylinders 3011. Through the guide cylinders 3011 to limit the rotation direction of the semi-circular rack 401, the rotation path of the semi-circular rack 401 is ensured to be stable. At the same time, both ends of the semi-circular rack 401 are bolted to the hoisting plate 501 to realize the detachable assembly between the semi-circular rack 401 and the hoisting plate 501.

[0045] Further, according to Figure 2 、 Figure 8 and Figure 9It can be seen that a rotating block 802 is fixed to the end face of the shaft rod of the linkage bevel gear block 801 that is rotationally fitted with the bearing and the mounting cylinder 201, and a longitudinal plate 4021 is fixed to the end face of the shaft rod of the angle tooth plate 402 that is rotationally fitted with the flat cylinder 301 through the bearing. When it is necessary to control the rotation of the linkage bevel gear block 801, the rotating block 802 can be directly controlled to rotate. Furthermore, the rotating block 802 will drive the linkage bevel gear block 801 to rotate, and thereby drive the conical ring gear block 304 meshing with the linkage bevel gear block 801 to rotate and move accordingly. At the same time, the angle tooth plate 402 is controlled to rotate. Thus, the angle tooth plate 402 will drive the semi-circular rack 401 to rotate and move in the flat cylinder 301, ensuring the adjustment of the semi-circular rack 401 in the counterclockwise or clockwise direction.

[0046] Embodiment 2: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 , on the basis of the specific Embodiment 1, the extension plate 601, the linkage plate 602, the bidirectional shaft bar 603 and multiple travel bars 5021 cooperate to work, so as to be able to drive the multiple travel bars 5021 to perform synchronous telescopic activities, thereby realizing rapid adjustment according to the size of the electronic device and improving the working efficiency of the adjustment.

[0047] Specifically, the hoisting assembly 5 includes a hoisting plate 501 located directly below the flat cylinder 301 and L-shaped plates 502 located at the four diagonal positions of the hoisting plate 501. An extended installation assembly 6 for telescoping the L-shaped plates 502 is arranged inside the groove 5011 opened at the lower end of the hoisting plate 501. The extended installation assembly 6 includes an extension plate 601 located at the middle position of the upper end of the hoisting plate 501 and a linkage plate 602 located inside the groove 5011. Four linkage bars 6021 arranged in a circumferential and uniformly distributed manner along the axial direction are fixed to the circumferential wall surface of the linkage plate 602. A bidirectional shaft bar 603 flush with the lower end surface of the linkage plate 602 is arranged on the lower surface of each linkage bar 6021. Square openings 5013 communicating with the inside of the groove 5011 are opened at the four corner parts of the extension plate 601. The travel bars 5021 fixed to the vertical end surfaces of the L-shaped plates 502 slide through the inside of the square openings 5013;

[0048] Since the sizes of each electronic device are different, it is necessary to adjust the installation structure according to the size of the electronic device. However, mostly the method of adjusting the installation structure one by one is adopted. By using the above structure, when it is necessary to adjust the L-shaped plate 502 uniformly, the extension plate 601 can be directly controlled to rotate forward. Thus, the extension plate 601 will drive the linkage plate 602 to rotate in the groove 5011, and the linkage plate 602 will push the bidirectional shaft bar 603 towards the corresponding stroke bar 5021 through the linkage bar 6021, so as to push the stroke bar 5021 out of the inner position of the square opening 5013. When the linkage bar 6021, the bidirectional shaft bar 603 and the stroke bar 5021 are in the same straight line, at this time, the distance that the stroke bar 5021 is pushed out from the inside of the square opening 5013 is the largest. Therefore, when continuing to rotate forward, the subsequent rotation will drive the stroke bar 5021 to contract, so as to control the L-shaped plate 502 to reconnect with the end angle position of the hoisting plate 501, which will cause the extension plate 601 to be unable to continue rotating. Therefore, when performing the telescopic operation again, the extension plate 601 can be controlled to rotate reversely to ensure that the L-shaped plate 502 can continue to perform the telescopic operation.

[0049] Embodiment Three: Please refer to Figure 5 and Figure 6 , on the basis of the specific Embodiment Two, by using the stroke adjustment, the linkage plate 602 and the bidirectional shaft bar 603, it is ensured that the three will not exceed the lower end surface of the L-shaped plate 502, and it is ensured that the L-shaped plate 502 and the electronic device can be stably installed.

[0050] Specifically, the lower end surface of the linkage plate 602 is flush with the lower end surface of the hoisting plate 501, the lower end surface of the stroke bar 5021 is flush with the lower end surface of the hoisting plate 501. The shaft rods fixed to the end surfaces of the stroke bar 5021 away from the L-shaped plate 502 and the shaft rods fixed to the end surfaces of the linkage bar 6021 away from the linkage plate 602 are all rotationally matched with the shaft hole positions at both ends of the adjacent bidirectional shaft bar 603. The shaft rod fixed between the extension plate 601 and the linkage plate 602 is rotationally matched with the hoisting plate 501 through a bearing;

[0051] By using the above structure, since the stroke bar 5021, the linkage plate 602 and the bidirectional shaft bar 603 are all flush with the lower end surface of the hoisting plate 501, when assembling the electronic device and the L-shaped plate 502 with bolts, the situation that the installation cannot be carried out due to the excessive protrusion of the stroke bar 5021, the linkage plate 602 and the bidirectional shaft bar 603 will not occur;

[0052] It should be noted that the shaft holes at both ends of the bidirectional shaft bar 603 are directly sleeved on the shaft rods at the ends of the linkage bar 6021 and the stroke bar 5021, so as to ensure that the connection positions of the bidirectional shaft bar 603 with the linkage bar 6021 and the stroke bar 5021 can rotate and will not fall off.

[0053] Embodiment 4: Please refer to Figure 2 、 Figure 3 and Figure 7 . On the basis of the specific Embodiment 1, through the pushing of the sliding plate 7011 by the spring 7012, it is ensured that the positioning tooth plate 702 and the limit rack 704 will not easily disengage from the meshing state. At the same time, the sliding plate 7011 and the moving sleeve 701 are limited through the vertical port 2013, so that the positioning tooth plate 702 and the limit rack 704 can only move up and down.

[0054] Specifically, a plurality of vertical ports 2013 communicating with the inside of the annular groove 2011 are opened on the outer wall of the mounting cylinder 201. A sliding plate 7011 is arranged inside the mounting cylinder 201 directly above the positioning tooth plate 702. The shaft rod fixed between the sliding plate 7011 and the moving sleeve 701 passes through the inside of the vertical port 2013. The spring 7012 fixed on the upper end surface of the sliding plate 7011 abuts against the inner top surface of the mounting cylinder 201. The sliding plate 7011, the positioning tooth plate 702 and the limit rack 704 are sequentially fixed from top to bottom through the arranged connecting rod 703. The used connecting rod 703 will pass through the connecting part of the conical ring gear block 304, the rotating cylinder 302 and the flat cylinder 301;

[0055] Through the setting and use of the above structure, when the moving sleeve 701 is controlled to move upward inside the annular groove 2011, the moving sleeve 701 will drive the sliding plate 7011 to slide in the mounting cylinder 201, and will drive the positioning tooth plate 702 and the limit rack 704 to move upward through the connecting rod 703. Thus, it can be ensured that the upward moving distances of the positioning tooth plate 702 and the limit rack 704 are the same. Therefore, after the moving sleeve 701 is released, the positioning tooth plate 702 and the limit rack 704 will move downward and can be reset to the initial position consistently. At the same time, the spring 7012 will be compressed during the upward movement of the sliding plate 7011. When the sliding plate 7011 is released, the spring 7012 at this time will also push the sliding plate 7011 downward, thereby improving the moving efficiency of the positioning tooth plate 702 and the limit rack 704 and the reset efficiency of the positioning tooth plate 702 and the limit rack 704. And through the pushing of the sliding plate 7011 by the spring 7012, when the sliding plate 7011 is not affected by external forces, the sliding plate 7011 will not easily move upward inside the mounting cylinder 201, so as to ensure that the positioning tooth plate 702 and the limit rack 704 will not easily disengage from the meshing state. At the same time, the shaft rod fixed between the moving sleeve 701 and the sliding plate 7011 passes through the position of the vertical port 2013, and the vertical port 2013 will limit the moving sleeve 701 and the sliding plate 7011, making the two unable to rotate, so that the positioning tooth plate 702 and the limit rack 704 can only move up and down.

[0056] Embodiment 5: Please refer to Figure 7 andFigure 8 , on the basis of the first specific embodiment, by the positions of the spherical blocks 3021 in the annular rail grooves 2014 and the spherical ports 3031, the friction received by the middle plate 303 can be reduced. By positioning the toothed plate 702 in the positioning toothed opening 3041, the planar cylinder 301 can be limited.

[0057] Specifically, a positioning toothed opening 3041 meshing with the positioning toothed plate 702 is provided at the middle position of the upper end surface of the conical ring toothed block 304. A middle plate 303 connected to the inner bottom surface of the installation cylinder 201 is fixed to the outer wall of the rotating cylinder 302. An annular rail groove 2014 is provided on the inner bottom surface of the installation cylinder 201. A plurality of spherical ports 3031 provided on the lower end surface of the middle plate 303 are each internally embedded with a spherical block 3021 cooperating with the annular rail groove 2014;

[0058] Through the setting and use of the above structure, when controlling the rotation of the planar cylinder 301, the conical ring toothed block 304 will drive the rotating cylinder 302 to rotate inside the installation cylinder 201, thereby driving the middle plate 303 to rotate accordingly. Thus, the middle plate 303 will drive the spherical block 3021 to rotate in the annular rail groove 2014. The annular rail groove 2014 limits the spherical block 3021 to position the middle plate 303, the rotating cylinder 302, and the conical ring toothed block 304, ensuring the stable meshing of the conical ring toothed block 304 and the linkage conical tooth block 801. At the same time, through the rotation of the spherical block 3021 in the annular rail groove 2014 and the self-rotation of the spherical block 3021 inside the spherical port 3031, the friction received by the middle plate 303 can be reduced. After inserting the positioning toothed plate 702 into the positioning toothed opening 3041, the positioning toothed plate 702 meshes with the positioning toothed opening 3041. Therefore, the positioning toothed plate 702 limits the conical ring toothed block 304, thereby limiting the planar cylinder 301.

[0059] Embodiment Six: Please refer to Figure 6 and Figure 10 , on the basis of the second specific embodiment, the stroke bar 5021 is limited at two points by the calibration shaft and the T-shaped block 5022 to ensure that the stroke bar 5021 is stably located in the square opening 5013.

[0060] Specifically, four adjustment openings 5012 respectively communicating with the inside of the square opening 5013 are provided on the upper end surface of the hoisting plate 501. A T-shaped block 5022 slidingly fitted with the adjustment opening 5012 is fixed to the upper surface of the stroke bar 5021 far from the end of the L-shaped plate 502. A calibration shaft 5014 is fixed at a position close to the L-shaped plate 502 on two opposite surfaces inside each square opening 5013. Stroke openings 5023 are provided on the side surfaces of the stroke bar 5021 corresponding to the calibration shafts 5014. Each calibration shaft 5014 slidably resides in the stroke opening 5023;

[0061] When the stroke bar 5021 expands and contracts inside the square opening 5013, the calibration shaft 5014 will slide along the inner position of the stroke opening 5023 at this time, and will drive the T-shaped block 5022 to slide along the inside of the adjustment opening 5012. Through the two-point limit of the stroke bar 5021 by the T-shaped block 5022 and the calibration shaft, it is ensured that the stroke bar 5021 is stably located in the square opening 5013. At the same time, since the stroke bar 5021 is located in the square opening 5013, the stroke bar 5021 is limited by the square opening 5013, so that the stroke bar 5021 can only slide along the path of the square opening 5013 during the pushing process.
