DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0054] It should also be noted here that in order to avoid obscuring the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, while other details that are not very relevant to the present application are omitted.

[0055] It should be emphasized that the term “include / comprises” when used herein refers to the presence of features, elements, steps or components, but does not exclude the presence or addition of one or more other features, elements, steps or components.

[0056] It should also be noted that, unless otherwise specified, the term “connection” herein may refer not only to a direct connection but also to an indirect connection involving an intermediate.

[0057] Hereinafter, embodiments of the present application will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0058] like Figures 1 to 12 As shown, one aspect of the present application provides an umbrella drying system, an umbrella drying module, wherein the umbrella drying module includes a traction rope, an umbrella drying device 200, a winch 100 and a fixed pulley assembly.

[0059] The fixed pulley assembly is used to be arranged above the umbrella drying device 200 and the hoist 100, the traction rope cooperates with the fixed pulley assembly, and the traction rope is connected to both the umbrella drying device 200 and the hoist 100.

[0060] The winch 100 is used to drive the umbrella drying device 200 to rise relative to the fixed pulley block via the traction rope, and the winch 100 is also used to drive the umbrella drying device 200 to descend relative to the fixed pulley block via the traction rope.

[0061] When the umbrella drying system provided by the present application is used, the parachute to be dried is hung on the umbrella drying unit, and the winch 100 is started. The winch 100 pulls the wire rope to raise the umbrella drying device. When the umbrella drying device rises to a preset height, the winch 100 is closed to achieve the purpose of drying the parachute.

[0062] The umbrella drying system provided in the embodiment of the present application comprises a plurality of the umbrella drying modules. The number of the umbrella drying modules may be 2-5, such as 2, 3, 4 or 5, and preferably, the number of the umbrella drying modules is 4.

[0063] like Figures 1 to 3 As shown, the umbrella drying device 200 includes a crossbeam 220 and an umbrella drying unit 210, and the umbrella drying unit 210 includes a driving member 211, a transmission assembly and an umbrella drying rack 218. The crossbeam 220 is preferably used to be arranged above the ground, and the transmission assembly includes a first swing rod 214, one end of the first swing rod 214 is pivoted to the crossbeam 220, and the other end of the first swing rod 214 is pivoted to the umbrella drying rack 218, and the driving member 211 is installed on the crossbeam 220, and the driving member 211 is connected to the first swing rod 214, so as to drive the first swing rod 214 through the driving member 211, and then drive the umbrella drying rack 218 to swing relative to the crossbeam 220.

[0064] The swinging of the umbrella rack 218 relative to the crossbeam 220 described in the embodiment of the present application means that the umbrella rack 218 can move back and forth between two positions relative to the crossbeam 220; the ground can be an outdoor ground or an indoor ground.

[0065] When the umbrella drying device 200 provided in the present application is in use, a parachute is set on the umbrella drying rack 218 so that the parachute moves with the umbrella drying rack 218, and the driving member 211 is started so that the driving member 211 drives the first swing rod 214, thereby driving the umbrella drying rack 218 to swing relative to the crossbeam 220. Since the parachute on the umbrella drying rack 218 swings together with the umbrella drying rack 218, on the one hand, it is easier for water droplets to drip from the parachute during the swinging process of the parachute, and on the other hand, it also increases the intensity of the interaction between the parachute and the surrounding air, and increases the flow rate of the airflow around the parachute, so that the parachute can be dried faster, thereby shortening the drying time required for the parachute and improving the parachute drying efficiency.

[0066] Optionally, the driving member 211 is installed on the top of the beam 220, the umbrella drying rack 218 is located below the beam 220, the top end of the first swing rod 214 is pivoted to the beam 220, and the bottom end of the first swing rod 214 is pivoted to the umbrella drying rack 218, so that the plane where the swing trajectory of the first swing rod 214 is located is parallel to the length direction of the beam 220. The driving member 211 is generally fixed to the cross beam 220 through a connecting member. The driving member 211 is installed on the top of the cross beam 220 to be supported by the cross beam 220. Then, the gravity of the driving member 211 is difficult to act on the connecting member, thereby reducing the risk of failure of the connecting member and improving the reliability of the umbrella drying device 200. The umbrella drying rack 218 is located below the cross beam 220. When the parachute is taken or placed, it is not easy to be hindered by other structures on the umbrella drying device 200, which facilitates the placement of the parachute on the umbrella drying rack 218 and the removal of the parachute from the umbrella drying rack 218. The plane where the swing trajectory of the first swing rod 214 is located is parallel to the length direction of the cross beam 220. Then, it is difficult for the first swing rod 214 to collide with the cross beam 220 when swinging, so that the first swing rod 214 can be arranged at any position in the length direction of the cross beam 220, thereby improving the flexibility of the arrangement of the umbrella drying unit 210 on the cross beam 220, and then making the umbrella drying device 200 suitable for more indoor or outdoor drying sites. Of course, the driving member 211 may be disposed below the crossbeam 220 , the umbrella drying rack 218 may be disposed on the side of the crossbeam 220 , and / or the first swinging rod 214 may be swung in a direction perpendicular to the crossbeam 220 .

[0067] Optionally, the transmission assembly further comprises a first connecting rod 212 and a second connecting rod 213, one end of the first connecting rod 212 is fixed to the rotating rod of the driving member 211, the driving member 211 is used to drive the first connecting rod 212 to rotate, the first connecting rod 212 is perpendicular to the transmission rod, the other end of the first connecting rod 212 is pivoted to one end of the second connecting rod 213, and the other end of the second connecting rod 213 is pivoted to the first swinging rod 214. When the driving member 211 is started, the transmission rod of the driving member 211 rotates, the first connecting rod 212 rotates with the transmission rod because it is fixedly connected to the transmission rod, and the end of the second connecting rod 213 connected to the first connecting rod 212 rotates with the first connecting rod 212. In this process, the end of the second connecting rod 213 connected to the umbrella rack 218 drives the umbrella rack 218 to swing, so that the rotation of the transmission rod of the driving member 211 can drive the umbrella rack 218 to swing continuously. Of course, the driving member 211 can also be a linear driving member, the transmission rod of the linear driving member is perpendicular to the first swing rod 214, and the transmission rod of the linear driving member is pivotally connected to the first swing rod 214. The transmission rod of the linear driving member moves back and forth, driving the first swing rod 214, and then driving the umbrella rack 218 to swing.

[0068] Optionally, the transmission assembly includes two first swinging rods 214, and the two first swinging rods 214 are located on opposite sides of the crossbeam 220. That is, the two first swinging rods 214 are both pivotally connected to the crossbeam 220, and the two first swinging rods 214 are both pivotally connected to the umbrella drying rack 218. The two first swinging rods 214 drive the umbrella drying rack 218 to swing as a whole, thereby improving the stability of the swing of the umbrella drying rack 218. In the embodiment of the present application, the second connecting rod 213 can be pivotally connected to one of the two first swinging rods 214, or the second connecting rod 213 can be pivotally connected to both of the first swinging rods 214.

[0069] Optionally, the transmission assembly also includes two second swing rods 217 that are arranged parallel to the first swing rod 214, one second swing rod 217 and one first swing rod 214 are located on one side of the beam 220, and the other second swing rod 217 and the other first swing rod 214 are located on the other side of the beam 220, the first swing rod 214 and the second swing rod 217 located on the same side of the beam 220 are arranged in the length direction of the beam 220, the top end of the second swing rod 217 is pivoted to the beam 220, and the bottom end of the second swing rod 217 is pivoted to the umbrella drying rack 218. That is to say, the second swing rod 217 will swing together with the first swing rod 214 and the umbrella rack 218. Since the second swing rod 217 is arranged parallel to the first swing rod 214, the second swing rod 217 plays a certain guiding role in the swinging of the umbrella rack 218 during the swinging process. The two second swing rods 217 jointly guide the swinging of the umbrella rack 218, and combined with the two first swing rods 214 to drive the umbrella rack 218, further improving the swinging stability of the umbrella rack 218.

[0070] Optionally, the transmission assembly further includes a first connecting shaft, a second connecting shaft, a first bearing, a second bearing, a first bearing seat 215 and a second bearing seat 216, the first bearing seat 215 and the second bearing seat 216 are both fixed to the top of the crossbeam 220, the first bearing is mounted on the first bearing seat 215, the first connecting shaft is mounted on the first bearing, the two ends of the first connecting shaft are connected to the top of the two first swinging rods 214 in a one-to-one correspondence, the second bearing is mounted on the second bearing seat 216, the second connecting shaft is mounted on the second bearing, and the two ends of the second connecting shaft are connected to the top of the two second swinging rods 217 in a one-to-one correspondence. In this way, it is not necessary to punch a hole in the crossbeam 220 so as to install the pivot shaft connected to the first connecting rod 212 in the hole, or to install the pivot shaft connected to the second connecting rod 213 in the hole, that is, when installing the transmission assembly and the umbrella drying rack 218, it is not necessary to destroy the structure of the crossbeam 220 itself, thereby making the crossbeam 220 have a good strength and maintaining a certain reliability. In the embodiment of the present application, the bottom end of the first swing arm 214 can be connected to the umbrella drying rack 218 through an axis, a bearing and a bearing seat, and the bottom end of the second swing arm 217 can also be connected to the umbrella drying rack 218 through an axis, a bearing and a bearing seat.

When the parachute is vertically hung upside down, each auxiliary hanging part 218b can hang two groups of parachute ropes on the edge of the parachute. It can be understood that the umbrella cloth ring 218a is an annular part, and the umbrella cloth ring 218a means that multiple parachutes can be distributed at different positions of the annular part.

[0078] The connecting component 150 described in the embodiment of the present application is separated from the first roller mounting gear 1a0, which means that there is no direct contact between the connecting component 150 and the first roller mounting gear 1a0; the driving shaft 190 is rotationally coordinated with the first base 160, and the first roller mounting gear 1a0 is rotationally coordinated with the driving shaft 190, and the rotational coordination is achieved through bearings.

[0079] The power switching device provided in the embodiment of the present application is applied to the winch 100 when in use, and the roller 110 of the winch 100 is installed on the power switching device, so that the roller 110 and the first roller mounting gear 1a0 are coaxially arranged and fixedly connected, and a traction rope (preferably a steel wire rope) for towing a parachute is wound around the roller 110, and the drive shaft 190 is connected to the motor (preferably a motor) for driving the rotation drive 180 device. When it is necessary to drive the roller 110 to rotate by the motor, the operating handle 140 is operated to drive the connecting assembly 150 so that the connecting assembly 150 is connected to the first roller mounting gear 1a0, so that the drive shaft 190 and the first roller mounting gear 1a0 are in transmission cooperation, and the motor drives the drive shaft 190, thereby driving the roller 110 to rotate; when it is necessary to manually drive the roller 110 to rotate, the operating handle 140 is operated to drive the connecting component 150 to separate the connecting component 150 from the first roller mounting gear 1a0, so that the first roller mounting gear 1a0 can rotate relative to the drive shaft 190, and the first roller mounting gear 1a0 is driven by the manual drive component 130.

[0080] When the power switching device provided in the present application is applied to the hoist 100, the roller 110 of the hoist 100 can be driven by the rotating drive member 180 connected to the drive shaft 190, or can be manually driven by the manual drive assembly 130, that is, the hoist 100 can be switched between electric drive and manual drive, so that when a power outage occurs, the hoist 100 can still perform the parachute drying work by manual drive. The rotating drive member 180 is preferably an electric motor.

[0081] Optionally, the power switching device provided in the embodiment of the present application further includes the connecting assembly 150 including a transmission gear 155 and an internal gear 151, the transmission gear 155 is fixed to the driving shaft 190, the first roller installation gear 1a0 and the transmission gear 155 are both used for transmission cooperation with the internal gear 151, and the operating handle 140 is used to drive the internal gear 151 to slide and cooperate with the first roller installation gear 1a0 and the transmission gear 155 in the axial direction of the driving shaft 190. When it is necessary to make the driving shaft 190 and the first roller installation gear 1a0 transmission cooperation, the operating handle 140 is operated to drive the internal gear 151 to move toward the first roller installation gear 1a0, and the internal gear 151 is meshed with the first roller installation gear 1a0 and the transmission gear 155 at the same time. When it is necessary to make the first roller installation gear 1a0 rotate relative to the driving shaft 190, the operating handle 140 is operated to drive the internal gear 151 to slide toward the transmission gear 155 until the internal gear 151 is separated from the first roller installation gear 1a0. Of course, holes can also be opened on the transmission gear 155 and the first roller mounting gear 1a0, and the connecting assembly 150 includes a connecting rod, which is driven by the operating handle 140. The transmission gear 155 and the first roller mounting gear 1a0 can be connected through the holes on the transmission gear 155 and the holes on the first roller mounting gear 1a0, so that the transmission gear 155 can drive the first roller mounting gear 1a0, and can also be separated from the first roller mounting gear 1a0 and / or the transmission gear 155, so that the first roller mounting gear 1a0 can rotate relative to the transmission gear 155 and the drive shaft 190.

[0082] Alternatively, if Figure 7 As shown, a groove 151a is formed on the outer wall of the inner gear 151, and the groove 151a extends in the circumferential direction of the inner gear 151. The connecting assembly 150 also includes a toggle member, and the toggle member cooperates with the groove 151a. The operating handle 140 is used to drive the toggle member, and then drive the inner gear 151 through the toggle member. When the operating handle 140 drives the toggle member, the toggle member cooperates with the groove 151a on the inner gear 151, so that the toggle member can drive the inner gear 151 to move. Of course, the toggle member can also be a slot body, and a part of the inner gear 151 is located in the slot body. The operating handle 140 drives the slot body to drive the inner gear 151 to move.

[0083] Optionally, the connecting assembly 150 also includes a connecting shaft 154 arranged parallel to the driving shaft 190, and the toggle member is a toggle bearing 152 that rotates with the connecting shaft 154, the toggle bearing 152 cooperates with the groove 151a, and the toggle bearing 152 is used to abut against the side wall of the groove 151a, and the operating handle 140 is used to drive the connecting shaft 154 and then drive the toggle bearing 152. When the operating handle 140 drives the connecting shaft 154 and then drives the toggle bearing 152, the toggle bearing 152 abuts against the side wall of the groove 151a, thereby driving the internal gear 151 to move. Since the toggle member adopts the toggle bearing 152 and the groove 151a extends in the circumferential direction of the internal gear 151, when the toggle bearing 152 cooperates with the groove 151a, the toggle bearing 152 will not interfere with the rotation of the internal gear 151, so that the power transmission between the transmission gear 155, the internal gear 151 and the first roller mounting gear 1a0 can be smoothly carried out. Of course, a toggle block can also be used to replace the toggle bearing 152. When the toggle block cooperates with the groove 151a, there is a gap between the toggle block and the side wall and bottom wall of the groove 151a to avoid interference with the rotation of the internal gear 151. When the internal gear 151 needs to be toggled, the toggle block abuts against the side wall of the groove 151a to drive the internal gear 151 to move.

[0084] Optionally, the connecting assembly 150 includes a plurality of connecting shafts 154 and a plurality of toggle bearings 152, each of the connecting shafts 154 is evenly distributed in the circumferential direction of the internal gear 151, and each of the toggle bearings 152 is matched with each of the connecting shafts 154 in a one-to-one correspondence. In other words, the plurality of toggle bearings 152 jointly participate in toggling the internal gear 151, so that the internal gear 151 can move smoothly and reliably in the axial direction of the drive shaft 190, thereby making it easier for the power of the winch 100 to switch between electric and manual.

If the inner gear 151 deflects during the movement, it is easy to form a large friction force between the inner gear 151 and the first roller mounting gear 1a0 and the transmission gear 155, which will hinder the movement of the inner gear 151 to a certain extent. In the embodiment of the present application, each guide shaft 153 is installed on the sliding member 156, so that each guide shaft 153 and each toggle member can move together with the sliding member 156, so that the movement of each toggle member has good synchronization and consistency, and then the inner gear 151 can move relatively smoothly relative to the first roller mounting gear 1a0 and the transmission gear 155. Preferably, a through groove is formed on the sliding member 156 to avoid the driving shaft 190. Of course, the operating handle 140 can also drive each toggle member to move separately; the guide shaft 153 can also be installed on the sliding member 156, and a hole is opened on the first base 160 so that the guide shaft 153 slides with the hole.

In this way, under the guiding action of the plurality of guide shafts 153, the sliding member 156 is not easy to deflect during the movement, and thus the internal gear 151 driven by each of the driving bearings 152 is not easy to deflect during the movement, and further the internal gear 151 can move relatively smoothly relative to the first roller mounting gear 1a0 and the transmission gear 155. In the embodiment of the present application, the number of through holes on the guide shaft 153 and the sliding member 156 is preferably two.

In this way, the operating handle 140 can be rotated by rotating the toggle shaft 157 and the toggle fork 158, thereby sequentially driving the sliding member 156, the connecting shaft 154, the toggle member and the internal gear 151 to move in the axial direction of the driving shaft 190. In the embodiment of the present application, the shifting shaft 157 can be on the inner side of the U-shaped structure or on the outer side of the U-shaped structure.

[0088] Optionally, the shift fork 158 further includes a shift protrusion 158c, which protrudes from the first shift part 158b on the side facing the second shift part 158d, and is used to abut against the sliding member 156. When the operating handle 140 drives the shift fork 158 to shift the sliding member 156 in the direction close to the second shift part 158d, the shift protrusion 158c abuts against the sliding member 156 to drive the sliding member 156 to move. In the embodiment of the present application, preferably, a transmission shaft 190 avoidance notch for cooperating with the drive shaft 190 is formed on both the first shift part 158b and the second shift part 158d. Of course, the shift protrusion 158c can also be provided on the second shift part 158d.

During operation, the operating handle 140 is operated to drive the toggle shaft 157 to rotate, and then the internal gear 151 is driven to move in the axial direction of the drive shaft 190 until the internal gear 151 cooperates with the first roller mounting gear 1a0 and the transmission gear 155, and the locking pin 172 is operated to make the locking pin 172 cooperate with the locking hole, so that the toggle shaft 157 cannot rotate, and the internal gear 151 remains in a state of cooperating with the first roller mounting gear 1a0 and the transmission gear 155. When the operating handle 140 needs to be operated again and the toggle shaft 157 needs to be rotated, the locking pin 172 can be pulled out of the locking hole. In this way, when the rotating drive member 180 is used to drive the roller 110 of the winch 100, the internal gear 151 and the first roller mounting gear 1a0 are not easily separated, thereby improving the safety and reliability of the use of the winch 100.

In this way, when the locking pin 172 is matched with the locking hole, the bayonet 174a on the pin cap 174 is matched with the slot on the pin seat 173. When the locking pin 172 needs to be separated from the locking hole, the tension of the tension spring is overcome, the pin cap 174 is pulled to pull the locking pin out of the locking hole, and at the same time, the bayonet 174a is also pulled out of the slot, and the pin cap 174 is rotated so that the bayonet 174a and the end of the slot are abutted under the tension of the tension spring. When the locking pin 172 needs to be matched with the locking hole again, the pin cap 174 is rotated so that the position of the bayonet 174a corresponds to the slot, and under the tension of the tension spring, the bayonet 174a is matched with the slot, thereby making the locking pin 172 match with the locking hole. Of course, the bayonet 174a can also be located on the pin seat 173, and the slot can be located on the pin cap 174.

[0091] Optionally, the power switching device provided in the embodiment of the present application further includes a second roller mounting gear 120 coaxially arranged with the first roller mounting gear 1a0, the second roller mounting gear 120 is rotationally matched with the driving shaft 190, the first roller mounting gear 1a0 is fixed to the second roller mounting gear 120, the diameter of the second roller mounting gear 120 is larger than the diameter of the first roller mounting gear 1a0, and the second roller mounting gear 120 is transmission matched with the manual driving component 130. In this way, the gears matched with the manual driving component 130 and the gears matched with the internal gear 151 are distinguished, so that the manual driving component 130 is not easy to interfere with the movement of the internal gear 151, thereby improving the safety of use.

[0092] In one embodiment of the present application, the winch 100 includes a roller 110, a rotating drive member 180 and a power switching device provided in an embodiment of the present application, the rotating drive member 180 is transmission-connected to the drive shaft 190, the roller 110 is coaxially arranged with the drive shaft 190, and the roller 110 is fixed to the first roller mounting gear 1a0.

[0093] The winch 100 provided in the embodiment of the present application adopts the power switching device provided in the embodiment of the present application.

The pawl 138 is used to cooperate with the ratchet assembly 134. The first sleeve 133 is threadedly connected with the manual drive shaft 135. The first sleeve 133 is used to abut against the ratchet assembly 134 to drive the manual drive shaft 135 to rotate by rotating the first sleeve 133.

[0097] The limiting member 13 f cooperates with both the first shaft sleeve 133 and the manual drive shaft 135 to limit the relative position between the first shaft sleeve 133 and the manual drive shaft 135 .

[0098] The rotational fit described in the embodiments of the present application is preferably a rotational fit achieved through a bearing.

[0099] The manual drive assembly 130 provided in the embodiment of the present application, when in use, the manual drive shaft 135 is matched with the roller 110 of the winch 100, the first sleeve 133 is threadedly connected with the manual drive shaft 135, and the first sleeve 133 is rotated to make the first sleeve 133 abut against the ratchet assembly 134, and then the first sleeve 133 is continued to be rotated to rotate the manual drive shaft 135, thereby driving the roller 110 to rotate. In the process of the ratchet assembly 134 rotating with the manual drive shaft 135, the pawl 138 cooperates with the ratchet assembly 134 to limit the ratchet assembly 134, and then limits the manual drive shaft 135. When the roller 110 is rotated by electric drive, the manual drive shaft 135 will rotate with the roller 110. Before the electric drive is started, the first sleeve 133 is rotated first to move the first sleeve 133 away from the ratchet assembly 134, so that the ratchet assembly 134 can rotate freely relative to the manual drive shaft 135. However, in the process of the manual drive shaft 135 rotating with the electric drive, the first sleeve 133 will produce a certain vibration, and the threaded connection between the first sleeve 133 and the manual drive shaft 135 may be loosened, causing the first sleeve 133 to move toward the ratchet assembly 134, causing the first sleeve 133 to abut against the ratchet assembly 134, and the cooperation between the ratchet assembly 134 and the pawl 138 will work again, hindering the normal operation of the electric drive.

[0100] The manual drive assembly 130 provided in the present application cooperates with both the first sleeve 133 and the manual drive shaft 135 after the first sleeve 133 and the ratchet assembly 134 are separated in the axial direction of the manual drive shaft 135, and limits the relative position between the first sleeve 133 and the manual drive shaft 135, so that even if vibration occurs during the rotation of the manual drive shaft 135, it is not easy for the first sleeve 133 to overcome the limitation and move toward the ratchet assembly 134 and abut against the ratchet assembly 134, thereby making it difficult for the cooperation between the ratchet assembly 134 and the pawl 138 to take effect during the electric drive of the winch 100, so that the winch 100 can proceed smoothly under the electric drive.

[0101] Optionally, the manual drive assembly 130 provided in the embodiment of the present application further includes a second bushing 132, which is coaxially arranged with the first bushing 133, and the second bushing 132 is fixedly connected with the first bushing 133, and an axis end groove 13g is formed on the second bushing 132, and the axis end groove 13g is formed at one end of the second bushing 132 which is close to the first bushing 133, and one end of the manual drive shaft 135 is an abutting end located in the axis end groove 13g, and the limiting member 13f is used to abut against both the abutting end and the bottom of the axis end groove 13g. In this way, the limiting member 13f is respectively in contact with the abutting end and the bottom of the shaft end groove 13g, so that the abutting end and the bottom of the shaft end groove 13g are not easy to get close to each other, and the distance between the abutting end and the bottom of the shaft end groove 13g is limited, thereby limiting the relative position of the second sleeve 132 and the manual drive shaft 135. Since the first sleeve 133 is fixedly connected to the second sleeve 132, the relative position between the first sleeve 133 and the manual drive shaft 135 is limited, so that the first sleeve 133 is not easy to move in the direction close to the ratchet assembly 134. In the embodiment of the present application, the limiting member 13f can be an elastic member or a rigid member. Of course, a hole can also be drilled on the first sleeve 133 and the manual drive shaft 135 so that the positioning pin cooperates with the pin hole to limit the relative position between the first sleeve 133 and the manual drive shaft 135.

In this way, one end of the threaded rod 13e is screwed into the shaft end groove 13g through the threaded hole 13h, and the end of the threaded rod 13e is abutted against the abutting end of the manual drive shaft 135, thereby limiting the position between the manual drive shaft 135 and the second sleeve 132. Of course, the extending direction of the threaded hole 13h can also be tilted relative to the axial direction of the manual drive shaft 135, or the through hole can be a pin hole extending in the radial direction of the second sleeve 132, and a pin hole is also provided at the corresponding position of the manual drive shaft 135, and the stopper 13f is a pin, which defines the relative position of the manual drive shaft 135 and the second sleeve 132 by cooperating with the pin hole on the manual drive shaft 135 and the pin hole on the second sleeve 132.

The star-shaped handle 13d is provided to facilitate the staff to hold and rotate the threaded rod 13e, thereby facilitating the threaded rod 13e to be screwed into the threaded hole 13h and abut against the abutting end.

[0105] Optionally, the stopper 13f is an elastic member, and the elastic member is located in the shaft end groove 13g.

[0106] Optionally, the first shaft sleeve 133 is detachably connected to the second shaft sleeve 132, and the stopper 13f is detachably connected to the second shaft sleeve 132. In this way, when the stopper 13f is needed to limit the position between the manual drive shaft 135 and the first shaft sleeve 133, the stopper 13f can be put into the shaft end receiving groove 13g, and when the stopper 13f is not needed to limit the position between the manual drive shaft 135 and the first shaft sleeve 133, the stopper 13f can be taken out.
