Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary components for the life test of air fryers, and specifically to an energy efficiency test device and test method for air fryers. Background Art

[0002] An air fryer is a small household kitchen appliance that uses rapidly circulating hot air to cook food, achieving a frying-like effect with far less oil consumption than traditional frying methods.

[0003] The patent with the patent announcement number CN217111438U relates to an air fryer life test device, including a frame body and a fryer body. The fryer bodies are respectively placed on both sides of the top surface of the frame body. The frame body is fixed with limiting components for pressing and limiting at the rear and both sides of the fryer body. The frame body is vertically fixed with vertical cylindrical tracks on the front side parts of the fryer body. The beneficial effects are as follows: This patent sets two workstations on the top surface of the frame body, and two types of button test components are tightly fitted on the horizontal cylindrical tracks of the two workstations, namely a micro-cylinder directly pushing a piston push rod to test an electronic button and a stepping motor driving a pressing plate to reciprocate and rotate a mechanical button. In this way, the life stability tests of products with mechanical buttons and electronic buttons can be carried out simultaneously, improving the general application range of the device, reducing the equipment investment cost, and being conducive to large-scale promotion and use.

[0004] In the above patent, it has the function of simultaneously testing air fryers with mechanical buttons and air fryers with electronic buttons. By setting two types of button test components on the horizontal cylindrical track, it is beneficial to improve the general application range of the device. However, when conducting button tests, for air fryers of different brands and models, the operator needs to adjust the positions of the micro-cylinder directly pushing the piston push rod and the pressing plate. The direct movement of the micro-cylinder directly pushing the piston push rod and the pressing plate on the vertical cylindrical track will result in too large frictional force, and too large frictional force will cause jamming. This situation becomes inefficient when testing air fryers of multiple models and is not conducive to adjusting the positions of the micro-cylinder directly pushing the piston push rod and the pressing plate. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an energy efficiency test device and test method for air fryers, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An air fryer energy efficiency testing device and testing method, including an operating table, on the top of which a circular groove and a rectangular groove are provided, and further including an adjusting device and a clamping device; wherein, the adjusting device includes a bottom tube, a U-shaped rod, a micro-cylinder push rod, a knob, an L-shaped plate, a baffle, a short plate, a roller and a T-shaped plate. When adjusting the position of the U-shaped rod, manually rotate the knob. The rotation of the knob drives the rotation of the L-shaped plate. Manually move the knob away from the bottom tube, and the movement of the knob drives the L-shaped plate to move away from the bottom tube. The bottom tube is fixedly installed on the top of the operating table. The U-shaped rod is slidably installed on the top of the bottom tube. The micro-cylinder push rod is slidably installed on the surface of the U-shaped rod. The knob slidably penetrates through the inner and outer walls of the bottom tube. The L-shaped plate is fixedly installed on the surface of the knob. The baffle is fixedly installed on the surface of the bottom tube. The short plate is fixedly installed on the surface of the micro-cylinder push rod. The roller is rotatably installed on the surface of the short plate. The T-shaped plate slidably penetrates through the surface of the micro-cylinder push rod. A circular hole is provided on the surface of the U-shaped rod, and the surface of the knob is in contact with the inner wall of the circular hole. During the movement of the knob, it separates from the circular hole on the U-shaped rod, so that the vertical limit of the knob on the U-shaped rod is released. A chute is provided on the top of the U-shaped rod, and the surface of the roller is in contact with the inner wall of the chute.

[0007] According to the above technical solution, a first volute spring is provided between the knob and the bottom tube. Manually rotate the knob, and during the rotation of the knob, the first volute spring is compressed. A card slot is provided on the surface of the roller, and the bottom of the T-shaped plate is in contact with the inner wall of the card slot. Manually move the T-shaped plate upward, and the movement of the T-shaped plate separates from the card slot on the surface of the roller, so that the rotational limit of the T-shaped plate on the roller is released. A first spring is provided between the T-shaped plate and the micro-cylinder push rod.

[0008] According to the above technical solution, the clamping device includes a driving motor, a mounting plate, a sliding rod, a bent plate, a rotating shaft, a clamping plate and a contact piece. Start the driving motor, and the output end of the driving motor moves to drive the mounting plate to move away from the driving motor. The movement of the mounting plate drives the sliding rod to move away from the driving motor. The driving motor is fixedly installed on the top of the operating table. The mounting plate is fixedly installed on the output end of the driving motor. The sliding rod slidably penetrates through the inside of the mounting plate. The bent plate is fixedly installed on the surface of the sliding rod. The rotating shaft is rotatably installed in the inside of the mounting plate. The clamping plate is fixedly installed on the surface of the rotating shaft. When the mounting plate moves towards the bent plate, it drives the rotating shaft to move towards the bent plate, and the movement of the rotating shaft drives the clamping plate to move towards the bent plate. The contact piece is fixedly installed on the surface of the clamping plate. A first tooth block is fixedly installed on the surface of the sliding rod, and a second tooth block is fixedly installed on the surface of the clamping plate.

[0009] According to the above technical solution, a second spring is arranged between the sliding rod and the carrying plate. When the carrying plate moves towards the bent plate, the second spring is compressed, and the deformed second spring exerts a reaction force on the sliding rod. A second scroll spring is arranged between the rotating shaft and the carrying plate, and a first corrugation is formed on the surface of the contact piece.

[0010] According to the above technical solution, the energizing device includes a power supply box, a sliding tube, a plug, a linkage rod, a Z-shaped piece, a short block and a pressing piece. During the rotation of the clamping plate, it contacts the surface of the linkage rod, so that the rotation of the clamping plate drives the linkage rod to move, and the movement of the linkage rod drives the sliding tube to move. The power supply box is fixedly installed on the top of the operating table. The sliding tube is slidably installed in the rectangular groove of the operating table. The plug slidably penetrates through the inner and outer walls of the sliding tube. The linkage rod is fixedly installed on the top of the sliding tube. The Z-shaped piece is fixedly installed on the surface of the plug. The short block is fixedly installed on the surface of the sliding tube. The pressing piece is fixedly installed inside the rectangular groove. The movement of the sliding tube drives the short block to move. During the movement of the short block, it contacts the surface of the pressing piece, so that the movement of the short block exerts a thrust on the pressing piece. The power supply box is connected to the plug through an electric wire. One end of the Z-shaped piece away from the plug is fixedly installed on the inner wall of the sliding tube.

[0011] According to the above technical solution, a third spring is arranged between the sliding tube and the operating table. During the movement of the sliding tube, the third spring is compressed, so that the deformed third spring exerts a reaction force on the sliding tube. The Z-shaped piece is elastic. When the sliding tube moves, it compresses the Z-shaped piece, and the deformed Z-shaped piece exerts a reaction force on the sliding tube under the influence of its own elasticity. The pressing piece is elastic.

[0012] According to the above technical solution, the protection device includes a bending piece, a mounting frame, a rotating rod, a fixing plate, a supporting plate and a protruding piece. During the movement of the bottom of the U-shaped rod, it contacts the top of the supporting plate, so that the movement of the U-shaped rod drives the supporting plate to move downward, and the movement of the supporting plate drives the fixing plate to move downward. The bending piece is fixedly installed at the bottom of the inner wall of the bottom tube. The mounting frame is fixedly installed on the top of the bending piece. The rotating rod is fixedly installed on the surface of the mounting frame. The fixing plate is rotatably installed on the surface of the rotating rod. The movement of the fixing plate drives the rotating rod to move downward, and the movement of the rotating rod drives the mounting frame to move downward. The supporting plate is fixedly installed on the surface of the fixing plate. The protruding piece slidably penetrates through the inner wall of the bottom tube.

[0013] According to the above technical solution, the bending piece is elastic. When the mounting frame moves downward, it compresses the bending piece, and the bending piece exerts a reaction force on the mounting frame during the deformation process. The surface of the supporting plate contacts the inner wall of the bottom tube. A first inclined surface is formed on the surface of the protruding piece. The bottom of the fixing plate contacts the first inclined surface of the protruding piece, so that the downward movement of the fixing plate drives the protruding piece to move. A fourth spring is arranged between the protruding piece and the bottom tube.

[0014] A test method for an air fryer energy efficiency test device includes:

[0015] Step 1: Place the air fryer on the top of the operating table, manually rotate the air fryer so that the side of the air fryer with the button faces the micro cylinder push rod, and finally power on the air fryer;

[0016] Step 2: Manually turn the knob to drive the L-shaped plate to rotate, and then move the knob in a direction away from the bottom tube. The movement of the knob drives the L-shaped plate to move in a direction away from the bottom tube;

[0017] Step 3: Manually move the door-shaped rod downward, and the movement of the door-shaped rod drives the micro-cylinder push rod to move downward. The micro-cylinder push rod moves to the top of the air fryer button and then stops moving;

[0018] Step 4: Start the micro cylinder push rod. The output end of the micro cylinder push rod contacts the button during the movement, so that the air fryer is started by the micro cylinder push rod.

[0019] The present invention provides an air fryer energy efficiency testing device, which has the following beneficial effects:

[0020] (1) In the air fryer energy efficiency test device, when the knob moves, it separates from the circular hole on the door-shaped rod, so that the limit of the door-shaped rod is released. By installing an L-shaped plate on the surface of the knob, the operator can adjust the position of the door-shaped rod only after correct operation, thereby reducing the occurrence of incorrect operation. The movement of the micro-cylinder push rod drives the movement of the short plate, and the movement of the short plate drives the movement of the roller. The roller rotates in the slide groove, so that the micro-cylinder push rod can move smoothly, avoiding instability or jamming caused by friction.

[0021] (2) In the air fryer energy efficiency testing device, the deformed spring 2 applies a reaction force to the sliding rod, and the bent plate clamps the air fryer under the influence of the reaction force. The spring 2 applies a reaction force to the bent plate, so that the bent plate can fit tightly with the air fryer, which helps to improve the clamping stability. The corrugation 1 of the contact piece contacts the surface of the air fryer during movement, and increases the clamping contact area to avoid the bent plate being unable to effectively clamp the round air fryer, thereby improving the versatility of clamping.

[0022] (3) In the air fryer energy efficiency test device, the sliding tube moves to squeeze the Z-shaped piece, and the squeezed Z-shaped piece exerts a reaction force on the sliding tube. By installing an elastic Z-shaped piece between the sliding tube and the plug, the sliding tube is prevented from continuing to move after the plug is misaligned, thereby improving the service life of the plug. The short block moves to exert a thrust on the retaining piece, and the retaining piece is deformed under the influence of the thrust. The intermittent contact between the short block and the retaining piece produces a slight shake, which can reduce the friction during plugging and unplugging, thereby making the plug plugging and unplugging smoother.

[0023] (4)In this air fryer energy efficiency test device, when the bending piece deforms, it exerts a reaction force on the mounting bracket, affecting the moving speed of the mounting bracket. By applying the reaction force to the mounting bracket through the bending piece, the deceleration effect acts on the bottom of the U-shaped rod, which helps to improve the buffering effect. After the tab moves to a predetermined position and stops moving, the fixed plate cannot continue to move downward. The range of the fixed plate's descent is restricted by the tab, preventing the bending piece from being overly squeezed and causing it to break, thereby enhancing the safety during operation.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-6 , an embodiment of the present invention is: an air fryer energy efficiency test device, including an operating table 1. A circular groove is opened at the top of the operating table 1, and a rectangular groove is opened at the top of the operating table 1. It also includes an adjusting device and a clamping device; wherein, the adjusting device includes a bottom pipe 2, a U-shaped rod 3, a micro-cylinder push rod 4, a knob 5, an L-shaped plate 6, a baffle 7, a short plate 8, a roller 9 and a T-shaped plate 10. The bottom pipe 2 is fixedly installed at the top of the operating table 1. The U-shaped rod 3 is slidably installed at the top of the bottom pipe 2. The micro-cylinder push rod 4 is slidably installed on the surface of the U-shaped rod 3. The knob 5 slidably penetrates through the inner and outer walls of the bottom pipe 2. The L-shaped plate 6 is fixedly installed on the surface of the knob 5. The baffle 7 is fixedly installed on the surface of the bottom pipe 2. The short plate 8 is fixedly installed on the surface of the micro-cylinder push rod 4. The roller 9 is rotatably installed on the surface of the short plate 8. The T-shaped plate 10 slidably penetrates through the surface of the micro-cylinder push rod 4. A circular hole is opened on the surface of the U-shaped rod 3. The surface of the knob 5 is in contact with the inner wall of the circular hole. A chute is opened at the top of the U-shaped rod 3. The surface of the roller 9 is in contact with the inner wall of the chute. By installing the L-shaped plate 6 on the surface of the knob 5, only after the operator operates correctly can the position of the U-shaped rod 3 be adjusted, reducing the occurrence of accidental touches and helping to improve the safety during work.

[0037] A first scroll spring is arranged between the knob 5 and the bottom pipe 2. A card slot is opened on the surface of the roller 9. The bottom of the T-shaped plate 10 is in contact with the inner wall of the card slot. A first spring is arranged between the T-shaped plate 10 and the micro-cylinder push rod 4. By installing the short plate 8 and the roller 9 at the bottom of the moving micro-cylinder push rod 4, the stability of the micro-cylinder push rod 4 during movement is improved, avoiding instability or jamming caused by friction.

[0038] The clamping device includes a driving motor 111, a mounting plate 112, a sliding rod 113, a bent plate 114, a rotating shaft 115, a clamping plate 116 and a contact piece 117. The driving motor 111 is fixedly installed on the top of the operating table 1. The mounting plate 112 is fixedly installed on the output end of the driving motor 111. The sliding rod 113 slidably penetrates through the inside of the mounting plate 112. The bent plate 114 is fixedly installed on the surface of the sliding rod 113. The rotating shaft 115 is rotatably installed in the inside of the mounting plate 112. The clamping plate 116 is fixedly installed on the surface of the rotating shaft 115. The contact piece 117 is fixedly installed on the surface of the clamping plate 116. A first tooth block is fixedly installed on the surface of the sliding rod 113. A second tooth block is fixedly installed on the surface of the clamping plate 116. By contacting the air fryer through the contact piece 117, it is avoided that the bent plate 114 cannot effectively clamp the circular air fryer, which helps to improve the clamping stability.

[0039] A second spring is arranged between the sliding rod 113 and the mounting plate 112. A second volute spring is arranged between the rotating shaft 115 and the mounting plate 112. A first corrugation is formed on the surface of the contact piece 117. By squeezing the second spring, a reaction force is applied to the bent plate 114, so that the bent plate 114 is in close contact with the air fryer under the influence of the reaction force, ensuring that the air fryer will not shake during the test and affect the test results.

[0040] When this embodiment works, manually place the air fryer on the top of the operating table 1. When adjusting the position of the portal rod 3, manually rotate the knob 5 by ninety degrees. During the rotation of the knob 5, the first volute spring is squeezed. At the same time, the rotation of the knob 5 drives the L-shaped plate 6 to rotate by ninety degrees. Manually move the knob 5 in the direction away from the bottom tube 2. The movement of the knob 5 drives the L-shaped plate 6 to move in the direction away from the bottom tube 2. During the movement of the knob 5, it separates from the circular hole on the portal rod 3, so that the vertical limit of the knob 5 on the portal rod 3 is released. After moving the portal rod 3 downward to the specified position, manually move the knob 5 in the direction of the bottom tube 2. The movement of the knob 5 drives the portal rod 3 to move. During the movement of the knob 5, it contacts the circular hole on the portal rod 3, so that the knob 5 vertically limits the portal rod 3. By installing the L-shaped plate 6 on the surface of the knob 5, the occurrence of accidental touch is reduced, which helps to improve the safety during work. When adjusting the position of the micro cylinder push rod 4, manually move the T-shaped plate 10 upward. During the movement of the T-shaped plate 10, the first spring is squeezed. At the same time, the movement of the T-shaped plate 10 separates from the card slot on the surface of the roller 9, so that the rotational limit of the T-shaped plate 10 on the roller 9 is released. Manually move the micro cylinder push rod 4 to the specified position. The movement of the micro cylinder push rod 4 drives the short plate 8 to move. The movement of the short plate 8 drives the roller 9 to move. The surface of the roller 9 generates friction with the chute during the movement, so that the roller 9 rotates under the action of the friction force. By installing the short plate 8 and the roller 9 at the bottom of the micro cylinder push rod 4, the micro cylinder push rod 4 can move smoothly;

[0041] The driving motor 111 is started, and the output end of the driving motor 111 moves to drive the carrying plate 112 to move in a direction away from the driving motor 111. The carrying plate 112 moves to drive the sliding rod 113 to move in a direction away from the driving motor 111. The sliding rod 113 moves to drive the bent plate 114 to move in a direction away from the driving motor 111. The surface of the bent plate 114 contacts the surface of the air fryer during the movement, so that the carrying plate 112 squeezes the spring 2 when moving in the direction of the bent plate 114. The spring 2 is manually squeezed and deformed. The deformed spring 2 applies a reaction force to the sliding rod 113, so that the bent plate 114 clamps the air fryer under the influence of the reaction force. The reaction force is applied to the bent plate 114 by squeezing the spring 2, so that the bent plate 114 is tightly fitted with the air fryer under the influence of the reaction force, ensuring that the bent plate 114 can stably clamp the air fryer. When the mounting plate 112 moves toward the bent plate 114, it drives the rotating shaft 115 to move toward the bent plate 114. The movement of the rotating shaft 115 drives the clamping plate 116 to move toward the bent plate 114. The movement of the clamping plate 116 drives the contact piece 117 to move toward the bent plate 114. The tooth block 2 of the clamping plate 116 contacts the tooth block 1 of the sliding rod 113 during the movement. The tooth block 1 and the tooth block 2 are engaged, so that the clamping plate 116 rotates toward the air fryer during the movement. The rotation of the clamping plate 116 drives the rotating shaft 115 to rotate. The rotation of the rotating shaft 115 squeezes the second scroll spring. At the same time, the clamping plate 116 rotates toward the air fryer and drives the contact piece 117 to move toward the air fryer. The corrugation 1 of the contact piece 117 contacts the surface of the air fryer during the movement. The contact piece 117 increases the contact area with the air fryer, which helps to improve the stability of the clamping.

[0042] See also Figures 1-10 On the basis of the above embodiment, another embodiment of the present invention further includes a power supply device and a protective device; the power supply device includes a power supply box 121, a slide tube 122, a plug 123, a linkage rod 124, a Z-shaped piece 125, a short block 126 and a stopper 127, the power supply box 121 is fixedly mounted on the top of the operating table 1, the slide tube 122 is slidably mounted in the rectangular groove of the operating table 1, the plug 123 slides through the inner and outer walls of the slide tube 122, the linkage rod 124 is fixedly mounted on the top of the slide tube 122 The Z-shaped piece 125 is fixedly mounted on the surface of the plug 123, the short block 126 is fixedly mounted on the surface of the slide tube 122, and the retaining piece 127 is fixedly mounted inside the rectangular groove. The power supply box 121 is connected to the plug 123 through electric wires, and one end of the Z-shaped piece 125 away from the plug 123 is fixedly mounted on the inner wall of the slide tube 122. Slight shaking is generated by intermittent contact between the short block 126 and the retaining piece 127, so that the plug 123 shakes slightly when plugging and unplugging, which helps the plug 123 to be plugged and unplugged more smoothly.

[0043] A spring three is arranged between the sliding tube 122 and the operating platform 1. The Z-shaped piece 125 is elastic, and the abutting piece 127 is elastic. The Z-shaped piece 125 applies a reaction force to the sliding tube 122 to prevent the sliding tube 122 from continuing to move when the plug 123 is misaligned, which may cause damage to the plug 123, and helps to extend the service life of the plug 123.

[0044] The protection device includes a bending piece 131, a mounting bracket 132, a rotating rod 133, a fixing plate 134, a support plate 135 and a tab 136. The bending piece 131 is fixedly installed at the bottom of the inner wall of the bottom tube 2. The mounting bracket 132 is fixedly installed on the top of the bending piece 131. The rotating rod 133 is fixedly installed on the surface of the mounting bracket 132. The fixing plate 134 is rotatably installed on the surface of the rotating rod 133. The support plate 135 is fixedly installed on the surface of the fixing plate 134. The tab 136 slidably penetrates through the inner wall of the bottom tube 2. The range of downward movement of the fixing plate 134 is limited by the tab 136 to prevent the bending piece 131 from being directly broken due to excessive extrusion during the protection process, which helps to improve the safety during operation.

[0045] The bending piece 131 is elastic. The surface of the support plate 135 contacts the inner wall of the bottom tube 2. A first inclined surface is provided on the surface of the tab 136. A spring four is arranged between the tab 136 and the bottom tube 2. By applying a reaction force to the mounting bracket 132 by the bending piece 131, the function of slowing down the speed directly acts on the bottom of the portal rod 3, which helps to improve the buffering effect.

[0046] A test method for an air fryer energy efficiency test device includes:

[0047] Step 1: Place the air fryer on the top of the operating platform 1, manually rotate the air fryer so that the side of the air fryer with the button faces the micro cylinder push rod 4, and finally power on the air fryer.

[0048] Step 2: Manually rotate the knob 5 to drive the L-shaped plate 6 to rotate, and then move the knob 5 in a direction away from the bottom tube 2. The movement of the knob 5 drives the L-shaped plate 6 to move in a direction away from the bottom tube 2.

[0049] Step 3: Manually move the portal rod 3 downward. The movement of the portal rod 3 drives the micro cylinder push rod 4 downward. The micro cylinder push rod 4 stops moving after moving above the air fryer button.

[0050] Step 4: Start the micro cylinder push rod 4. The output end of the micro cylinder push rod 4 contacts the button during the movement process, so that the air fryer is started by the micro cylinder push rod 4.

[0051] When the present embodiment is working, the clamping plate 116 rotates toward the air fryer and contacts the surface of the linkage rod 124 away from the sliding tube 122, so that the clamping plate 116 rotates to drive the linkage rod 124 to move toward the air fryer, and the linkage rod 124 moves to drive the sliding tube 122 to move toward the air fryer. The sliding tube 122 squeezes the spring 3 during the movement, and the sliding tube 122 moves to drive the plug 123 to move toward the air fryer. The plug 123 moves to drive the Z-shaped piece 125 to move toward the air fryer. When the plug 123 is aligned with the socket of the air fryer, the plug 123 contacts the socket during the movement to complete the power-on of the air fryer. When the plug 123 is not aligned with the socket of the air fryer, the plug 123 contacts the surface of the air fryer during the movement, so that the sliding tube 122 continues to move. The Z-shaped piece 125 is moved and squeezed. The deformed Z-shaped piece 125 applies a reaction force to the slide tube 122 under the influence of its own elasticity. The reaction force applied to the slide tube 122 by the Z-shaped piece 125 prevents the plug 123 from being damaged when it is not aligned. The slide tube 122 moves and drives the short block 126 to move toward the abutment piece 127. The short block 126 contacts the surface of the abutment piece 127 during the movement, so that the short block 126 moves and applies a thrust to the abutment piece 127. The abutment piece 127 is deformed under the influence of the thrust. The short block 126 continues to move and separates from the contact surface of the abutment piece 127, so that the abutment piece 127 recovers under the influence of its own elasticity. The intermittent contact between the short block 126 and the abutment piece 127 produces a slight shake, which can make the plug 123 smoother when plugging and unplugging.

[0052] When an accident occurs during the adjustment of the position of the portal rod 3, the portal rod 3 moves downward under the influence of gravity. The bottom of the portal rod 3 contacts the top of the support plate 135 during the movement, causing the portal rod 3 to drive the support plate 135 to move downward. The movement of the support plate 135 drives the fixed plate 134 to move downward. The movement of the fixed plate 134 drives the rotating rod 133 to move downward. The movement of the rotating rod 133 drives the mounting bracket 132 to move downward. The downward movement of the mounting bracket 132 squeezes the bending piece 131, and the bending piece 131 deforms under the squeeze. During the deformation process, the bending piece 131 exerts a reaction force on the mounting bracket 132, causing the downward movement speed of the mounting bracket 132 to slow down under the influence of the reaction force. By the bending piece 131 exerting a reaction force on the mounting bracket 132, the function of slowing down the speed directly acts on the bottom of the portal rod 3. While the fixed plate 134 moves downward, the bottom of the fixed plate 134 contacts the inclined surface of the tab 136, causing the fixed plate 134 to drive the tab 136 to move away from the fixed plate 134. When the tab 136 moves, it squeezes the fourth spring. The fourth spring is squeezed and exerts a reaction force on the tab 136. The downward movement speed of the fixed plate 134 slows down under the influence of the reaction force. After the tab 136 moves to a predetermined position, it stops moving away from the fixed plate 134, preventing the fixed plate 134 from continuing to move downward. The range of the downward movement of the fixed plate 134 is limited by the tab 136, preventing the bending piece 131 from being directly broken due to excessive squeezing during the protection process.
