Description

Technical Field

[0001] The present invention belongs to the technical field of smoke detection, and specifically relates to a convenient installation device for a smoke detector. Background Technique

[0002] A smoke detector realizes fire prevention by monitoring the concentration of smoke. Inside the smoke detector, an ionization smoke sensor is adopted. The ionization smoke sensor is a sensor with advanced technology and stable and reliable operation, and is widely used in various fire alarm systems, with performance far superior to that of gas-sensitive resistor-based fire alarms. Smoke detectors are widely used in various indoor places. Since smoke rises when it occurs, most smoke detectors are mainly installed at high places, that is, on the ceiling. The common smoke detector is mainly composed of a smoke detector body and a base. During the actual installation process, the base needs to be installed first, and then the smoke detector body.

[0003] Since smoke detectors are mainly installed on the ceiling for use, and the common ceiling height of indoor buildings is more than two and a half meters, ordinary people cannot directly install them. Tools such as ladders are often used to climb to a high place before installing the smoke detector. During the actual installation process, multiple smoke detectors are often installed, and these smoke detectors are generally separated by a certain distance, resulting in the need for construction workers to frequently climb up and down the ladder to complete the installation, which will obviously reduce the installation efficiency. At the same time, some smoke detectors are installed in narrow channels where ladders are difficult to enter, and at this time, the operator cannot use the ladder for installation, and the use limitation is relatively large.

[0004] During the actual installation process of the smoke detector, the base needs to be installed first, and then the smoke detector is fixed. The common base is generally fixed to the ceiling with bolts. After the base is fixed, the smoke detector is rotated and clamped after being aligned with the base. Obviously, during installation, the operator needs to hold a screwdriver to first install the base and then install the smoke detector. Not only does the operator need to work at a height, but also needs to hold devices such as an electric screwdriver for operation, which will obviously increase the operation difficulty and the risk factor. Summary of the Invention

[0005] The purpose of the present invention is to provide a convenient installation device for a smoke detector to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: a convenient installation device for a smoke detector, including a main rod, wherein a secondary rod is provided inside the main rod. Limiting grooves are opened at both the left and right ends of the inner cavity of the main rod. Linear motors are fixedly installed at the bottom ends of the inner cavities of the limiting grooves. The secondary rod is movably sleeved between the main rods. The top ends of the linear motors are fixedly connected to the bottom end of the secondary rod. A storage sleeve is fixedly installed at the top end of the secondary rod. A fixing frame is provided in the middle of the inner cavity of the storage sleeve. Activity grooves that completely penetrate are equiangularly opened at the top end of the fixing frame. A clamping assembly is provided inside the activity grooves. One end of the clamping assembly is fixedly installed with a tightening and positioning assembly. A movable plate is provided directly below the middle of the bottom end of the fixing frame. The bottom end of the movable plate is fixedly connected with an extension rod. The bottom end of the extension rod penetrates through the bottom ends of the secondary rod and the main rod.

[0007] Before using the device, it is first necessary to prepare the base to be installed, the smoke detector, and the bolts for installation, and the number of bolts should not exceed four. Determine the installation position of the smoke detector. At the same time, it is necessary to determine the installation height according to the storey height of the room. At the same time, use an external battery to connect to the power supply of the device to continuously supply power to the device. At the same time, it is necessary to ensure that the hydraulic oil inside the device is in the initial position to complete the preparation work.

[0008] As a further technical solution of the present invention, a handle is fixedly installed at the bottom end of the extension rod. A fixing plate is fixedly installed at a position near the bottom end of the inner cavity of the main rod. The fixing plate is movably sleeved with the extension rod. An activity seat is provided between the fixing plate and the handle.

[0009] As a further technical solution of the present invention, the activity seat is fixedly sleeved with the extension rod. A return spring is movably sleeved on the outer side of the extension rod. The upper and lower ends of the return spring are fixedly connected to the bottom end of the fixing plate and the top end of the activity seat respectively.

[0010] When the position of the smoke detector is determined, first place the base or the smoke detector to be installed inside the clamping assembly, and turn on the power supply of the linear motor to drive the extension of the linear motor. At this time, the displacement of the secondary rod relative to the main rod can be driven, thereby adjusting the overall height of the device until the clamping assembly inside the storage sleeve carries the base or the smoke detector up until it is directly below the position to be installed for installation operations.

[0011] As a further technical solution of the present invention, the clamping assembly includes a connecting rod. Grooves are equiangularly opened on the outer side of the movable plate. The connecting rod is movably connected to the groove through a rotating shaft. The other end of the connecting rod is movably connected to a fixing seat through a rotating shaft. An activity block is fixedly installed at the top end of the fixing seat.

[0012] As a further technical solution of the present invention, the movable block is movably clamped with the movable slot, clamping jaws are fixedly installed at the top ends of the movable blocks, anti-slip grooves are formed on the inner sides of the clamping jaws, and the number of the clamping jaws is four and they are evenly distributed above the fixing frame.

[0013] As a further technical solution of the present invention, mounting plates are fixedly installed at equal distances on the backs of the clamping jaws, positioning holes that completely penetrate are formed at the top ends of the mounting plates, and one ends of the backs of the clamping jaws are fixedly connected to the tightening and positioning assembly.

[0014] When installing the smoke detector body, an upward pressure can be applied to the handle. At this time, the return spring is compressed, and at the same time, the movable seat and the extension rod move upward, and the movable plate follows to move upward. When the movable plate follows to move upward, since the outer side of the movable plate is connected to a connecting rod, and the connecting rod is connected to the fixed seat and the movable block, and the movable block can only displace relative to the movable slot, when the movable plate moves upward, the other end of the connecting rod deflects outward accordingly, and drives the movable block to displace outward relative to the movable slot. At this time, the four movable blocks will move relatively away from each other. At this time, the bottom end of the smoke detector is placed between the four clamping jaws, and the handle is released. At this time, the return spring automatically drives the extension rod, the movable seat and the movable plate to reset, and the four clamping jaws move relatively closer to complete the reset and clamp the bottom end of the smoke detector. At this time, the device can be lifted to make the smoke detector correspond to the already installed base, and it is inserted into the base and the installation of the smoke detector is completed by rotating the device. After the installation is completed, the fixation between the device and the smoke detector can be released by continuing to apply an upward pressure to the handle, and the device is pushed out to complete the installation of the smoke detector body.

[0015] By using the lifting action, the opening of the clamping assembly can be directly completed to place the smoke detector, and when released, the clamping and fixing of the smoke detector can be directly completed by using the reset action. At the same time, the height of the smoke detector can be increased by using the length of the device. The fixing of the smoke detector can be completed by using the lifting and releasing actions, avoiding the problems that traditional devices require operators to use ladders to climb heights for installation or that installation cannot be carried out at heights due to the operating space. This enables the operator to hold the device on the ground and complete the rapid installation of the smoke detector, significantly improving the installation efficiency.

[0016] As a further technical solution of the present invention, the tightening and positioning assembly includes a fixed sleeve, a power tank is fixedly connected to the bottom end of the fixed sleeve, an oil storage tank is fixedly communicated with the left end of the power tank, hydraulic oil is stored inside the oil storage tank, and the left end of the oil storage tank is fixedly connected to the back of the clamping jaw.

[0017] As a further technical solution of the present invention, the right end of the power tank is fixedly communicated with an oil pipeline, the other end of the oil pipeline is fixedly communicated with the right side near the bottom end of the fixed sleeve, a telescopic rod is movably installed inside the power tank, and an impeller located inside the power tank is fixedly sleeved on the outer side of the telescopic rod.

[0018] As a further technical solution of the present invention, the top end of the telescopic rod sequentially penetrates through the top end of the power tank and the bottom end of the fixed sleeve. A base located inside the fixed sleeve is fixedly installed at the top end of the telescopic rod. A screw head is fixedly installed at the top end of the base. The screw head is movably clamped with the fixed sleeve. Extension frames are fixedly installed on both the left and right sides at the bottom end of the screw head. A piston plate is fixedly connected to the bottom end of the extension frame. The inner side of the piston plate is movably sleeved with the telescopic rod, and the outer side of the piston plate is movably sleeved with the fixed sleeve.

[0019] As a further technical solution of the present invention, a through hole is provided in the middle of the top end of the screw head, and a marking pen is movably installed inside the through hole. A connecting rod located inside the through hole is fixedly installed at the bottom end of the marking pen. A limiting spring is movably sleeved on the outer side of the connecting rod. The upper and lower ends of the limiting spring are respectively fixedly connected to the bottom end of the marking pen and the top end of the base.

[0020] When it is necessary to install the base of the smoke detector, the screw to be installed can be first passed through the two positioning holes and placed upside down above the screw head. At the same time, the handle is lifted upward, which can drive the four clamping jaws to move relatively away from each other. At the same time, the base is placed between the four clamping jaws, and the installation hole at the bottom end of the base corresponds to the positioning hole. At the same time, the handle is released, and at this time, the four clamping jaws move relatively closer to clamp the base. At this time, the device is held high to correspond to the predetermined installation position, and the oil pumps inside the four oil storage tanks are turned on. At this time, the hydraulic oil located inside the oil storage tank enters the inside of the power tank and impacts the impeller. At this time, the impeller can be driven to rotate and drive the telescopic rod to rotate. At this time, the entire screw head rotates accordingly. At the same time, the hydraulic oil can enter the bottom end of the fixed sleeve through the oil pipeline and apply an upward pressure to the piston plate. At this time, the overall screw head can be driven to move upward. At this time, the screw head can rotate and move upward, driving the screw at its top end to rotate and move upward until the screw is driven into the ceiling, and the fixation of the base can be completed.

[0021] By using the lifting action, the placement of the base can be completed, and by using the reset action, the clamping and fixing of the base can be completed. At the same time, after the base reaches the predetermined position, the automatic screwing of the screw can be realized, avoiding the need for operators to climb high and hold tools to fix the base screws in the traditional device, reducing the danger of operators climbing high and the convenience during installation. This makes the device not only capable of quickly installing the base and automatically screwing the screw, but also assisting in the quick clamping and fixing of the detector body, improving the safety and portability during installation, and is suitable for popularization and use.

[0022] Third Embodiment:

[0023] Before installing the base and the detector body, the pre-installation position can be selected first. At the same time, by applying an upward pressure to the handle, the extension rod and the movable plate move upward, and when one end of the connecting rod deflects, it can drive the four jaws to approach relatively. When the handle is released, it can drive the jaws to move away relatively. At this time, the screw head at one end of the jaw moves accordingly. By selecting a suitable position as the installation hole position and applying an overall upward pressure to the device, the marking pen inside the screw head comes into contact with the top of the ceiling. At the same time, the limiting spring is compressed, and the pressure acting on the marking pen increases. The marking pen can then apply pressure to the ceiling until an imprint is left on the ceiling to complete the marking of the installation position.

[0024] By using the lifting and releasing actions, the position of the marking pen can be changed. At the same time, in cooperation with the height-adjustable main rod and sub-rod, the marking of the ceiling can be realized, enabling the marking of the installation position before installing the smoke detector to assist the normal progress of subsequent installation. This makes the device not only capable of pre-marking the installation position before installation, quickly installing the base and automatically screwing the screw, but also capable of quickly installing the smoke detector body, and is suitable for use during large-scale installation.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. By using the lifting action, the present invention can directly open the clamping component to place the smoke detector, and when released, use the reset action to directly complete the clamping and fixing of the smoke detector. At the same time, use the length of the device to raise the smoke detector. By using the lifting and releasing actions, the fixing of the smoke detector can be completed, avoiding the problems that traditional devices require operators to use ladders to climb high for installation or that installation cannot be carried out due to lack of operating space for climbing. This enables operators to hold the device on the ground to quickly install the smoke detector, significantly improving the installation efficiency.

[0027] 2. The present invention can complete the placement of the base by using the lifting action, and can complete the clamping and fixing of the base by using the reset action. At the same time, it can automatically drive the screw after the base reaches the predetermined position, avoiding the need for operators to climb high and hold tools to fix the base screws in the traditional device, reducing the danger of operators climbing high and the convenience during installation. The device can not only achieve the rapid installation of the base and the self-driving of screws, but also assist in the rapid clamping and fixing of the detector body, improving the safety and portability during installation, and is suitable for popularization and use.

[0028] 3. The present invention can change the position of the marker pen by using the lifting and loosening actions. At the same time, with the main rod and the auxiliary rod with adjustable heights, the marking of the ceiling can be achieved, enabling the marking of the installation position before the installation of the smoke detector to assist the normal progress of subsequent installation. The device can not only achieve the pre-marking of the installation position before installation, the rapid installation of the base and the automatic driving of screws, but also achieve the rapid installation of the smoke detector body, and is suitable for use during large-scale installation.

The bottom end of the extension rod 7 penetrates through the bottom ends of the auxiliary rod 2 and the main rod 1.

[0041] Before using the device, first, it is necessary to prepare the base to be installed, the smoke detector, and bolts for installation, and the number of bolts cannot exceed four. Determine the installation position of the smoke detector. At the same time, it is necessary to determine the installation height according to the floor height of the room. At the same time, connect an external battery to the power supply of the device to continuously supply power to the device. At the same time, it is necessary to ensure that the hydraulic oil inside the device is in the initial position to complete the preparation work.

[0042] As Figure 2 and Figure 3As shown in the figure, a handle 10 is fixedly installed at the bottom end of the extension rod 7. A fixing plate 6 is fixedly installed at a position near the bottom end inside the main rod 1. The fixing plate 6 is movably sleeved with the extension rod 7. An activity seat 8 is arranged between the fixing plate 6 and the handle 10. The activity seat 8 is fixedly sleeved with the extension rod 7. A return spring 9 is movably sleeved on the outer side surface of the extension rod 7. The upper and lower ends of the return spring 9 are fixedly connected between the bottom end of the fixing plate 6 and the top end of the activity seat 8.

[0043] When the position of the smoke detector is determined, first, the base or the smoke detector to be installed needs to be placed inside the clamping assembly 14, and the power supply of the linear motor 4 is turned on, which can drive the elongation of the linear motor 4. At this time, it can drive the displacement of the secondary rod 2 relative to the main rod 1, and then adjust the overall height of the device until the clamping assembly 14 inside the receiving sleeve 5 carries the base or the smoke detector up until it is directly below the position to be installed for installation operations.

[0044] As Figures 4 to 6 As shown in the figure, the clamping assembly 14 includes a connecting rod 141. Grooves are equiangularly formed on the outer side surface of the movable plate 13.

One end of the back surface of the claw finger 144 is fixedly connected to the tightening and positioning assembly 15.

[0045] First Embodiment:

[0046] When installing the smoke detector body, an upward pressure can be applied to the handle 10. At this time, the return spring 9 is compressed, and at the same time, the movable seat 8 and the extension rod 7 move upward accordingly, and the movable plate 13 follows and moves upward. When the movable plate 13 moves upward, since the outer side of the movable plate 13 is connected to the connecting rod 141, and the connecting rod 141 is connected between the fixed seat 142 and the movable block 143, and the movable block 143 can only displace relative to the movable groove 12, when the movable plate 13 moves upward, the other end of the connecting rod 141 deflects outward accordingly, and drives the movable block 143 to displace outward relative to the movable groove 12. At this time, the four movable blocks 143 will move relatively away from each other. At this time, the bottom end of the smoke detector is placed at the position between the four clamping jaws 144, and the handle 10 is released. At this time, the return spring 9 automatically drives the extension rod 7, the movable seat 8 and the movable plate 13 to reset. The four clamping jaws 144 then move relatively closer to complete the reset and clamp the bottom end of the smoke detector. At this time, the device can be lifted so that the smoke detector corresponds to the installed base, and it is inserted into the base and the installation of the smoke detector is completed by rotating the device. After the installation is completed, the fixation between the device and the smoke detector can be released by continuing to apply an upward pressure to the handle 10, and the device is pushed out to complete the installation of the smoke detector body.

[0047] By using the lifting action, the opening of the clamping assembly 14 can be directly completed to realize the placement of the smoke detector, and when released, the clamping and fixing of the smoke detector can be directly completed by using the reset action. At the same time, the height of the smoke detector can be completed by using the length of the device. The fixing of the smoke detector can be completed by using the lifting and releasing actions, avoiding the problems that traditional devices require operators to use ladders to climb heights for installation or there is no space for climbing installation, so that the operator can hold the device on the ground to complete the rapid installation of the smoke detector, significantly improving the installation efficiency.

[0048] Such as Figures 6 to 9As shown in the figure, the tightening and positioning assembly 15 includes a fixing sleeve 151. The bottom end of the fixing sleeve 151 is fixedly connected to a power tank 152. The left end of the power tank 152 is fixedly communicated with an oil storage tank 153. The oil storage tank 153 stores hydraulic oil inside. The left end of the oil storage tank 153 is fixedly connected to the back of the jaw 144. The right end of the power tank 152 is fixedly communicated with an oil delivery pipe 154. The other end of the oil delivery pipe 154 is fixedly communicated with the right side of the fixing sleeve 151 near the bottom end. An expansion rod 156 is movably installed inside the power tank 152. An impeller 155 located inside the power tank 152 is fixedly sleeved on the outer side of the expansion rod 156. The top end of the expansion rod 156 sequentially penetrates through the top end of the power tank 152 and the bottom end of the fixing sleeve 151. The top end of the expansion rod 156 is fixedly installed with a base 1510 located inside the fixing sleeve 151. A screw head 159 is fixedly installed at the top end of the base 1510. The screw head 159 is movably clamped with the fixing sleeve 151. Extension frames 158 are fixedly installed on both the left and right sides of the bottom end of the screw head 159. The bottom end of the extension frame 158 is fixedly connected to a piston plate 157. The inner side of the piston plate 157 is movably sleeved with the expansion rod 156. The outer side of the piston plate 157 is movably sleeved with the fixing sleeve 151. A through hole is opened in the middle of the top end of the screw head 159 and a marker pen 1513 is movably installed inside the through hole. A connecting rod 1512 located inside the through hole is fixedly installed at the bottom end of the marker pen 1513. A limiting spring 1511 is movably sleeved on the outer side of the connecting rod 1512. The upper and lower ends of the limiting spring 1511 are respectively fixedly connected to the bottom end of the marker pen 1513 and the top end of the base 1510. A micro oil pump is installed inside the oil storage tank 153.

[0049] Second Embodiment:

[0050] When the base of the smoke detector needs to be installed, the screw to be installed can be passed through the two positioning holes 146 and placed upside down above the screw head 159. At the same time, lift the handle 10 upward, which can drive the four jaws 144 to move relatively away from each other. At the same time, place the base between the four jaws 144 and make the installation holes at the bottom end of the base correspond to the positioning holes 146. Then release the handle 10. At this time, the four jaws 144 will move relatively closer to clamp the base. At this time, hold the device high to correspond it to the predetermined installation position and turn on the oil pumps inside the four oil storage tanks 153. At this time, the hydraulic oil located inside the oil storage tank 153 will immediately enter the inside of the power tank 152 and impact the impeller 155. At this time, the impeller 155 can be driven to rotate and drive the expansion rod 156 to rotate. At this time, the entire screw head 159 will rotate accordingly. At the same time, the hydraulic oil can enter the bottom end of the fixing sleeve 151 through the oil delivery pipe 154 and exert an upward pressure on the piston plate 157. At this time, the overall screw head 159 can be driven to move upward. At this time, the screw head 159 can rotate and move upward, driving the screw at its top to rotate and move upward until the screw is driven into the ceiling, and the fixation of the base can be completed.

[0051] By utilizing the lifting action, the placement of the base can be completed, and by using the reset action, the clamping and fixing of the base can be achieved. At the same time, after the base reaches the predetermined position, the automatic screwing of the screw can be realized, avoiding the need for the operator to climb high and hold tools to fix the base screws during the installation of the traditional device, reducing the danger of the operator climbing high and the convenience during installation. This enables the device to not only achieve the rapid installation of the base and the self-screwing of the screw, but also assist in the rapid clamping and fixing of the detector body, improving the safety and portability during installation, and is suitable for popularization and use.

[0052] Third Embodiment:

[0053] Before installing the base and the detector body, the pre-installation position can be selected first. At the same time, by applying an upward pressure to the handle 10, the extension rod 7 and the movable plate 13 move upward, and one end of the connecting rod 141 deflects, which can drive the four jaws 144 to approach relatively. When the handle 10 is released, the jaws 144 can be driven to move away relatively. At this time, the screw head 159 at one end of the jaws 144 moves accordingly. By selecting a suitable position as the installation hole position and applying an overall upward pressure to the device, the marking pen 1513 inside the screw head 159 comes into contact with the top of the ceiling at the same time, and the limit spring 1511 is compressed. The pressure acting on the marking pen 1513 increases, and the marking pen 1513 can apply pressure to the ceiling until an imprint is left on the ceiling to complete the marking of the installation position.

[0054] By utilizing the lifting and releasing actions, the position change of the marking pen 1513 can be realized. At the same time, in cooperation with the height-adjustable main rod 1 and sub-rod 2, the marking function of the ceiling can be achieved, enabling the marking of the installation position before the installation of the smoke detector to assist the normal progress of subsequent installation. This enables the device to not only achieve the pre-marking of the installation position before installation, the rapid installation of the base and the automatic screwing of the screw, but also achieve the rapid installation of the smoke detector body, and is suitable for use during large-scale installation.

[0055] Working Principle and Usage Process:

[0056] Before using the device, it is first necessary to prepare the base to be installed, the smoke detector, and the bolts for installation, and the number of bolts cannot exceed four. Determine the installation position of the smoke detector. At the same time, according to the storey height of the room, determine the installation height. At the same time, connect an external battery to the power supply of the device to continuously supply power to the device. At the same time, it is necessary to ensure that the hydraulic oil inside the device is in the initial position to complete the preparation work;

[0057] When the position of the smoke detector is determined, first place the base or smoke detector to be installed inside the clamping assembly 14 and turn on the power of the linear motor 4 to drive the extension of the linear motor 4. At this time, the displacement of the secondary rod 2 relative to the main rod 1 can be driven, thereby adjusting the overall height of the device until the clamping assembly 14 inside the receiving sleeve 5 carries the base or smoke detector up until it is directly below the installation position to perform the installation operation;

[0058] Before installing the base and the detector body, the pre-installation position can be selected first. At the same time, by applying an upward pressure to the handle 10, the extension rod 7 and the movable plate 13 move upward, and one end of the connecting rod 141 deflects to drive the four jaws 144 to move closer to each other. When the handle 10 is released, the jaws 144 can be driven to move away from each other. At this time, the screw head 159 at one end of the jaw 144 moves accordingly. By selecting a suitable position as the installation hole position and applying an overall upward pressure to the device, the marking pen 1513 inside the screw head 159 comes into contact with the top of the ceiling at this time, and the limiting spring 1511 is compressed. The pressure acting on the marking pen 1513 increases, and the marking pen 1513 can apply pressure to the ceiling until a mark is left on the ceiling to complete the marking of the installation position;

[0059] When installing the base of the smoke detector, first place the screw to be installed through the two positioning holes 146 and place it upside down above the screw head 159. At the same time, lift the handle 10 upward, which can drive the four jaws 144 to move away from each other. At the same time, place the base between the four jaws 144 and make the installation holes at the bottom of the base correspond to the positioning holes 146. Then release the handle 10. At this time, the four jaws 144 move closer to each other to clamp the base. At this time, hold the device high to correspond it to the predetermined installation position, and turn on the oil pumps inside the four oil storage tanks 153. At this time, the hydraulic oil inside the oil storage tank 153 immediately enters the inside of the power tank 152 and impacts the impeller 155. At this time, the impeller 155 can be driven to rotate and drive the telescopic rod 156 to rotate. At this time, the entire screw head 159 rotates accordingly. At the same time, the hydraulic oil can enter the bottom end of the fixed sleeve 151 through the oil delivery pipe 154 and apply an upward pressure to the piston plate 157. At this time, the overall upward movement of the screw head 159 can be driven. At this time, the screw head 159 can rotate and move upward, driving the screw at its top to rotate and move upward until the screw is driven into the inside of the ceiling to complete the fixation of the base;

[0060] When installing the smoke detector body, an upward pressure can be applied to the handle 10. At this time, the return spring 9 is compressed, and at the same time, the movable seat 8 and the extension rod 7 move upward accordingly, and the movable plate 13 follows and moves upward. When the movable plate 13 moves upward, since the outer side of the movable plate 13 is connected to the connecting rod 141, and the connecting rod 141 is connected between the fixed seat 142 and the movable block 143, and the movable block 143 can only displace relative to the movable groove 12, when the movable plate 13 moves upward, the other end of the connecting rod 141 deflects outward accordingly, and drives the movable block 143 to displace outward relative to the movable groove 12. At this time, the four movable blocks 143 will move relatively away from each other. At this time, place the bottom end of the smoke detector between the four clamping jaws 144, and release the handle 10. At this time, the return spring 9 automatically drives the extension rod 7, the movable seat 8 and the movable plate 13 to reset. The four clamping jaws 144 then move relatively closer to complete the reset and clamp the bottom end of the smoke detector. At this time, the device can be lifted so that the smoke detector corresponds to the already installed base, and it is inserted into the base and the installation of the smoke detector is completed by rotating the device. After the installation is completed, by continuing to apply an upward pressure to the handle 10, the fixation between the device and the smoke detector can be released, and the device can be pushed out to complete the installation of the smoke detector body.
