[0003] The prior art (authorization announcement number: CN118044929B) discloses a scoliosis traction bed with measurement function, belonging to the field of scoliosis traction bed technology. The patient lies on top of the supporting bed body, with the curved back resting on a transparent fixation plate, and the legs and head placed at the supporting bed body position. By activating the axillary positioning stretching part and the hip positioning stretching part, the axillary positioning stretching part is positioned under the patient's armpit, and the hip positioning stretching part is positioned on both sides of the patient's hips. The back detection camera detects the location of the patient's back curvature, and then the second horizontal movement part is activated to move the spinal curvature clamping part to both sides of the spinal curvature location. By activating the spinal curvature clamping part, the back is positioned on both sides, so that the spinal curvature position of the patient's back is positioned on top of the transparent fixation plate. By activating the first horizontal movement part, the adjustment frame is moved to move the patient's back in the opposite direction of the spinal curvature.

[0004] In this existing technology, only traction therapy can be performed on the patient. However, the patient's back muscles are not prevented from being loosened before traction therapy, which can easily lead to back muscle strain and reduce the user experience of the product.

[0014] The spinal traction device of the present invention has the following advantages compared with the prior art: 1. By moving the lifting plate up and down, the vibration mechanism and massage head assembly vibrate, aligning the positioning groove with the massage head assembly. This allows the massage head assembly to pass through the groove, enabling it to massage the patient lying on the support plate. This helps prevent relaxation of the patient's back muscles, reducing the risk of muscle strain during subsequent spinal traction and improving the user experience. Furthermore, by moving the headrest assembly via the first adjustment mechanism and the leg support assembly via the second adjustment mechanism, the distance between the headrest and leg support assemblies and the support plate can be adjusted to accommodate patients of different heights, further enhancing the user experience.

[0015] 2. By connecting the two first moving blocks to the bottom of the support plate and passing the first lead screw through the first threaded hole of the two first moving blocks, the first lead screw is simultaneously threadedly connected to the two first moving blocks, thereby rotating the first lead screw and causing the support plate to move, so as to adjust the position of the support plate.

[0016] 3. By placing two pusher blocks on the base plate and making the second inclined surfaces of the two pusher blocks fit into the first inclined surfaces on both sides of the lifting plate, the two pusher blocks push the lifting plate upward when they move relative to each other, thereby adjusting the height of the lifting plate; by installing four guide seats on the front and rear sides of the lifting plate respectively and making the four first guide rods pass through the four guide seats respectively, the lifting plate moves up and down along the first guide rods through the guide seats, thereby preventing the lifting plate from deviating when moving up and down and improving the stability of the lifting plate moving up and down.

[0017] 4. By mounting the first motor on the lifting plate and connecting the first motor to a rotating shaft, the first motor drives the rotating shaft to rotate; by connecting multiple sprockets to multiple rotating shafts respectively and simultaneously mounting chains on the outside of multiple sprockets, when one rotating shaft rotates, the rotating shaft drives the other rotating shafts to rotate through multiple sprockets and chains, thereby achieving synchronous rotation of multiple rotating shafts, which in turn drives multiple cams to rotate, thereby driving the massage head assembly to move up and down.

[0018] 5. When the lifting plate moves upward, the massage rod drives the massage rollers upward, causing the massage rollers to pass through the clearance groove and fit against the patient's back. Then, the first motor is activated, causing it to drive a rotating shaft to rotate. This rotating shaft, through multiple sprockets and chains, drives the remaining rotating shafts to rotate, thereby causing multiple rotating shafts to drive multiple cams to rotate. When the multiple cams rotate, the rotating cams will drive the massage rod to move up and down. When the massage rod moves upward, it stretches the first spring through the first limiting plate. Simultaneously, when the massage rod moves downward, the first spring resets and drives the massage rod downward, thus promoting the up and down movement of the first spring.

[0019] 6. By connecting the two second moving blocks to the bottom of the headrest assembly and passing the second lead screw through the second threaded holes of the two second moving blocks, the second lead screw is simultaneously threadedly connected to the two second moving blocks, thereby rotating the second lead screw and causing the headrest assembly to move, so as to adjust the position of the headrest assembly.

[0020] 7. By installing two third fixed plates on the top of the first support frame and rotatably connecting the two ends of the third screw to the two third fixed plates respectively, the two third fixed plates cooperate to support the third screw, thereby enabling the third screw to rotate between the two third fixed plates; by connecting two third moving blocks to the bottom of the leg support assembly and passing the third screw through the third threaded holes of the two third moving blocks, the third screw is simultaneously threadedly connected to the two third moving blocks, thereby enabling the rotation of the third screw to drive the leg support assembly to move, thereby adjusting the position of the leg support assembly.

[0021] 8. When preparing to activate the translation mechanism to move the support plate, pull the connecting plate downwards. This causes the connecting plate to move the positioning rod downwards, thus removing the positioning rod from the positioning hole. At this time, the connecting plate will move the second guide rod downwards, causing the second guide rod to press the second spring through the second limiting plate, thereby compressing the second spring. When the support plate is ready to reach its initial position, release the connecting plate. The second spring will then reset and move the second guide rod, connecting plate, and positioning rod upwards, bringing the positioning rod into contact with the bottom of the positioning seat. Then, continue moving the support plate, causing relative displacement between the positioning rod and the positioning seat. When the positioning rod aligns with the positioning hole, the second spring will reset and move the positioning rod upwards, embedding it into the positioning hole. This positions the positioning seat and support plate, ensuring that the clearance groove aligns with the massage head assembly.

[0022] 9. By connecting the contact plate to the connecting rod and positioning the contact plate above the connecting plate, the contact plate and the connecting rod can move up and down synchronously. This allows the connecting rod to move the connecting plate downwards via the contact plate when the second cylinder moves the connecting rod downwards, thus enabling the positioning rod to move out of the positioning hole and compressing the second spring. Simultaneously, when the second cylinder moves the connecting rod and the contact plate upwards, the contact plate disengages from the connecting plate, preventing interference between the contact plate and the connecting plate when the reset second spring moves the connecting plate upwards, thereby improving the user experience.

Detailed Implementation

[0024] The following are specific implementation cases and appendices. Figures 1 to 10 The present invention will be further described, but the present invention is not limited to these embodiments.

[0025] A spinal traction device, such as Figures 1 to 10As shown, the spinal traction device includes: a base plate 10, a first support frame 11, a translation mechanism 12, a support plate 13, a lifting mechanism 14, a lifting plate 15, a vibration mechanism 16, a massage head assembly 17, a relief groove 18, a first adjustment mechanism 19, a headrest assembly 20, a second adjustment mechanism 21, and a leg support assembly 22; the first support frame 11 is mounted on the base plate 10; the translation mechanism 12 is mounted on the first support frame 11; the support plate 13 is connected to the translation mechanism 12; the lifting mechanism 14 is mounted on the base plate 10 and is located within the first support frame 11; the lifting plate 15 is connected to the lifting mechanism 14; the vibration mechanism 16 is mounted on the lifting plate 15; multiple massage heads are included. The massage head assembly 17 is connected to the vibration mechanism 16. Multiple massage head assemblies 17 pass through the top of the first support frame 11 and are located below the support plate 13. Multiple clearance grooves 18 are disposed in the support plate 13 and are respectively opposite to the multiple massage head assemblies 17. The first adjustment mechanism 19 is installed on the top of the first support frame 11 and is located on one side of the support plate 13. The headrest assembly 20 is connected to the first adjustment mechanism 19. The second adjustment mechanism 21 is installed on the top of the first support frame 11 and is located on the other side of the support plate 13. The leg support assembly 22 is connected to the second adjustment mechanism 21.

[0026] By installing the first support frame 11 on the base plate 10, installing the translation mechanism 12 on the first support frame 11, and connecting the support plate 13 to the translation mechanism 12, the first support frame 11 supports the translation mechanism 12, thereby enabling the translation mechanism 12 to drive the support plate 13 to move and adjust the position of the support plate 13. By mounting the lifting mechanism 14 on the base plate 10 and connecting the lifting plate 15 to the lifting mechanism 14, the lifting mechanism 14 can drive the lifting plate 15 to move up and down, thereby adjusting the height of the lifting plate 15. By mounting the vibration mechanism 16 on the lifting plate 15 and connecting multiple massage head assemblies 17 to the vibration mechanism 16, and allowing the multiple massage head assemblies 17 to pass through the top of the first support frame 11, the lifting plate 15 can drive the vibration mechanism 16 and the massage head assemblies 17 to move up and down, thereby allowing the vibration mechanism 16 to drive the multiple massage head assemblies 17 to vibrate, and thus enabling the massage head assemblies 17 to massage the patient's back. By setting multiple clearance grooves 18 in the support plate 13 and having the multiple clearance grooves 18 respectively opposite to the multiple massage head assemblies 17, the massage head assemblies 17 can pass through the clearance grooves 18 and massage the patient lying on the support plate 13. By installing the first adjustment mechanism 19 on the top of the first support frame 11 and connecting the headrest assembly 20 to the first adjustment mechanism 19, the first adjustment mechanism 19 can drive the headrest assembly 20 to move, thereby adjusting the distance between the headrest assembly 20 and the support plate 13; by installing the second adjustment mechanism 21 on the top of the first support frame 11 and connecting the leg support assembly 22 to the second adjustment mechanism 21, the second adjustment mechanism 21 can drive the leg support assembly 22 to move, thereby adjusting the distance between the leg support assembly 22 and the support plate 13.

[0027] When using the product, first, have the patient lie on the support plate 13. Simultaneously, adjust the first adjustment mechanism 19 and the second adjustment mechanism 21 so that the patient's head can be placed on the headrest assembly 20 and the patient's legs on the leg support assembly 22. Then, activate the lifting mechanism 14, causing it to move the vibration mechanism 16 and the massage head assembly 17 upwards, allowing the massage head assembly 17 to pass through the relief groove 18. Next, activate the vibration mechanism 16, causing it to vibrate the massage head assembly 17, which then massages the patient's back, relaxing the patient's muscles. Then, stop the vibration mechanism 16 and activate the lifting mechanism 14, causing it to move the vibration mechanism 16 and the massage head assembly 17 downwards, allowing the massage head assembly 17 to move out of the relief groove 18. Finally, activate the translation mechanism 12, causing it to move the support plate 13 and the patient lying on it, thereby providing traction to the patient's spine.

[0028] With the above structure, by moving the lifting plate 15 up and down, the vibration mechanism 16 and the massage head assembly 17 move vertically. The vibration mechanism 16 then causes the massage head assembly 17 to vibrate, and the clearance groove 18 aligns with the massage head assembly 17, allowing the massage head assembly 17 to pass through it. This enables the massage head assembly 17 to massage the patient lying on the support plate 13, preventing relaxation of the patient's back muscles and reducing the risk of muscle strain during subsequent spinal traction, thus improving the user experience. By moving the headrest assembly 20 with the first adjustment mechanism 19 and the leg support assembly 22 with the second adjustment mechanism 21, the distance between the headrest assembly 20 and the leg support assembly 22 and the support plate 13 can be adjusted to accommodate patients of different heights, further enhancing the user experience.

[0029] Specifically, two clamps are installed on the support plate 13, and there is a gap between the two clamps; when the patient lies on the support plate 13, the patient is located between the two clamps, and the patient's arms are located on the outside of the two clamps, thereby avoiding relative displacement between the patient and the support plate 13 when the support plate 13 moves the patient, so as to improve the user experience of the product.

[0030] Specifically, the headrest assembly 20 is equipped with a first securing strap to secure the patient's shoulders to the headrest assembly 20; the leg support assembly 22 is equipped with a second securing strap to secure the patient's legs to the leg support assembly 22.

[0035] By placing two pusher blocks 141 on the base plate 10 and ensuring that the second inclined surfaces of the two pusher blocks 141 are respectively in contact with the first inclined surfaces on both sides of the lifting plate 15, the two pusher blocks 141 push the lifting plate 15 upward when they move relative to each other, thereby adjusting the height of the lifting plate 15. By installing two first cylinders 142 on the base plate 10 and connecting the two first cylinders 142 to the two pusher blocks 141 respectively, the first cylinders 142 drive the pusher blocks 141 to move, thereby adjusting the position of the pusher blocks 141. By setting two sliding grooves 143 on the top of the base plate 10 and connecting two sliders 144 to the bottom of the two pusher blocks 141 respectively, and embedding the two sliders 144 into the two sliding grooves 143 respectively, the pusher blocks 141 move along the sliding grooves 143 via the sliders 144, thereby preventing the pusher blocks 141 from deviating during movement and improving the stability of the pusher blocks 141's movement. By connecting one end of the four first guide rods 146 to the top of the base plate 10 and the other end of the four first guide rods 146 to the top of the first support frame 11, the base plate 10 and the first support frame 11 cooperate to support the four first guide rods 146, thereby improving the stability of the four first guide rods 146. By installing the four guide seats 145 on the front and rear sides of the lifting plate 15 respectively, and allowing the four first guide rods 146 to pass through the four guide seats 145 respectively, the lifting plate 15 can move up and down along the first guide rods 146 through the guide seats 145, thereby preventing the lifting plate 15 from deviating during up and down movement and improving the stability of the lifting plate 15 during up and down movement.

By mounting the first motor 164 on the lifting plate 15 and connecting the first motor 164 to a rotating shaft 162, the first motor 164 drives the rotating shaft 162 to rotate. By connecting multiple sprockets 165 to multiple rotating shafts 162 respectively, and simultaneously mounting chains 166 on the outside of multiple sprockets 165, when one rotating shaft 162 rotates, the rotating shaft 162 drives the other rotating shafts 162 to rotate through multiple sprockets 165 and chains 166, thereby enabling multiple rotating shafts 162 to rotate synchronously, which in turn drives multiple cams 163 to rotate, thereby driving the massage head assembly 17 to move up and down.

[0038] In embodiments of the present invention, such as Figure 3 and Figure 8 As shown, the massage head assembly 17 includes: a second support frame 171, a massage rod 172, a connecting groove, a massage wheel 173, a first limiting plate 174, and a first spring 175; the second support frame 171 is mounted on the lifting plate 15; the bottom of the massage rod 172 is in contact with the cam 163, and the massage rod 172 passes through the second support frame 171 and the first support frame 11 in sequence; the connecting groove is provided at the top of the massage rod 172; the massage wheel 173 is embedded in the connecting groove, the massage wheel 173 is rotatably connected to the massage rod 172, and the massage wheel 173 is opposite to the clearance groove 18; the first limiting plate 174 is fitted on the outside of the massage rod 172, and the first limiting plate 174 is located above the second support frame 171; the first spring 175 is fitted on the outside of the massage rod 172, one end of the first spring 175 is connected to the first limiting plate 174, and the other end of the first spring 175 is connected to the top of the second support frame 171.

[0039] By mounting the second support frame 171 on the lifting plate 15, and having the bottom of the massage rod 172 fit against the cam 163, the massage rod 172 passes sequentially through the second support frame 171 and the first support frame 11. This allows the lifting plate 15 to support the second support frame 171, thereby enabling the first and second support frames 171 to cooperate in guiding the massage rod 172. Consequently, the rotating cam 163 can drive the massage rod 172 to move up and down. By setting the connecting groove on the top of the massage rod 172, the massage wheel 173 is embedded in the connecting groove, allowing the massage wheel 173 to be rotatably connected to the massage rod 172. The massage wheel 173 is positioned opposite the relief groove 18, allowing the massage rod 172 to support the massage wheel 173, enabling the massage wheel 173 to rotate within the connecting groove. This allows the massage rod 172 to drive the massage wheel 173 through the relief groove 18, thus enabling the massage wheel 173 to massage the patient's back. By fitting the first limiting plate 174 onto the outside of the massage rod 172, the massage rod 172 and the first limiting plate 174 can move up and down synchronously. By fitting the first spring 175 onto the outside of the massage rod 172, connecting one end of the first spring 175 to the first limiting plate 174, and connecting the other end of the first spring 175 to the top of the second support frame 171, the second support frame 171 can support the first limiting plate 174 and the massage rod 172 through the first spring 175.

[0040] With the above structure, when the lifting plate 15 moves upward, the massage rod 172 drives the massage wheel 173 to move upward, so that the massage wheel 173 passes through the relief groove 18 and fits against the patient's back. Then, the first motor 164 is started, which drives a rotating shaft 162 to rotate. At the same time, the rotating shaft 162 drives the other rotating shafts 162 to rotate through multiple sprockets 165 and chains 166, so that the multiple rotating shafts 162 drive multiple cams 163 to rotate. When the multiple cams 163 rotate, the rotating cams 163 will drive the massage rod 172 to move up and down. When the massage rod 172 moves upward, the massage rod 172 stretches the first spring 175 through the first limiting plate 174. At the same time, when the massage rod 172 moves downward, the first spring 175 resets and drives the massage rod 172 to move downward, so as to promote the up and down movement of the first spring 175.

[0042] By installing two second fixed plates 191 on the top of the first support frame 11 and rotatably connecting the two ends of the second lead screw 192 to the two second fixed plates 191 respectively, the two second fixed plates 191 cooperate to support the second lead screw 192, thereby enabling the second lead screw 192 to rotate between the two second fixed plates 191; by connecting two second moving blocks 193 to the bottom of the headrest assembly 20 and passing the second lead screw 192 through the second threaded holes of the two second moving blocks 193, the second lead screw 192 is simultaneously threadedly connected to the two second moving blocks 193, thereby enabling the rotation of the second lead screw 192 to drive the headrest assembly 20 to move, thereby adjusting the position of the headrest assembly 20.

[0043] Specifically, two fifth movable blocks are installed at the bottom of the headrest assembly 20 and are located between two fifth fixed plates; the two ends of the second light bar are respectively connected to the two second fixed plates 191, and the second light bar passes through the two fifth movable blocks in sequence; the first handwheel is fitted on the outside of the second lead screw 192 so that the first handwheel can drive the second lead screw 192 to rotate, thereby reducing the difficulty of rotating the second lead screw 192.

[0044] In embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the second adjustment mechanism 21 includes: a third fixed plate 211, a third lead screw 212, and a third moving block 213; two third fixed plates 211 are installed on the top of the first support frame 11, and there is a gap between the two third fixed plates 211; a third external thread is provided on the outer wall of the third lead screw 212, and the two ends of the third lead screw 212 are rotatably connected to the two third fixed plates 211 respectively; a third threaded hole is provided in the third moving block 213, and a third internal thread is provided in the third threaded hole; the two third moving blocks 213 are connected to the bottom of the leg support assembly 22, and the third lead screw 212 passes through the third threaded hole of the two third moving blocks 213 in sequence; wherein, the third external thread and the third internal thread are adapted to each other.

[0045] By installing two third fixing plates 211 on the top of the first support frame 11 and rotatably connecting the two ends of the third screw 212 to the two third fixing plates 211 respectively, the two third fixing plates 211 cooperate to support the third screw 212, thereby enabling the third screw 212 to rotate between the two third fixing plates 211; by connecting two third moving blocks 213 to the bottom of the leg support assembly 22 and passing the third screw 212 through the third threaded holes of the two third moving blocks 213, the third screw 212 is simultaneously threadedly connected to the two third moving blocks 213, thereby enabling the rotation of the third screw 212 to drive the leg support assembly 22 to move, thereby adjusting the position of the leg support assembly 22.

[0046] Specifically, two sixth movable blocks are installed at the bottom of the leg support assembly 22 and are located between two sixth fixed plates; the two ends of the third optical bar are respectively connected to the two third fixed plates 211, and the third optical bar passes through the two sixth movable blocks in sequence; the second handwheel is fitted on the outside of the third lead screw 212 so that the second handwheel can drive the third lead screw 212 to rotate, thereby reducing the difficulty of rotating the third lead screw 212.

[0047] In embodiments of the present invention, such as Figures 7 to 10 As shown, the spinal traction device also includes: a positioning seat 23, a connecting plate 25, a positioning rod 26, a second mounting bracket 27, a second guide rod 28, a second limiting plate 29, and a second spring 30; the positioning seat 23 has two positioning holes 24, and the two positioning seats 23 are installed at the bottom of both sides of the support plate 13; the two connecting plates 25 are located above the first support frame 11, and the two connecting plates 25 are respectively located below the two positioning seats 23; the two positioning rods 26 are installed on the connecting plates 25, and the positioning rods 26 are opposite to the positioning holes 24; four second mounting brackets 27 are located inside the first support frame 11, and four... A second mounting bracket 27 is mounted on top of the first support bracket 11; four second guide rods 28 pass through the top of the four second mounting brackets 27 and the first support bracket 11 respectively, and the four second guide rods 28 are respectively connected to two connecting plates 25; four second limiting plates 29 are respectively located inside the four second mounting brackets 27, and the four second limiting plates 29 are respectively fitted on the outside of the four second guide rods 28; a second spring 30 is fitted on the outside of the second guide rods 28, one end of the second spring 30 is connected to the second limiting plate 29, and the other end of the second spring 30 is connected to the second mounting bracket 27.

[0048] By installing two positioning seats 23 on the bottom sides of the support plate 13, and placing two connecting plates 25 below the two positioning seats 23, and installing two positioning rods 26 on the connecting plates 25 with the positioning rods 26 facing the positioning holes 24, the connecting plates 25 can drive the two positioning rods 26 to move up and down. This allows the positioning rods 26 to be inserted into the positioning holes 24 when the connecting rods 32 drive the positioning rods 26 to move upwards, thus positioning the positioning seats 23 and the support plate 13. By installing four second mounting brackets 27 on the top of the first support frame 11, and passing four second guide rods 28 through the tops of the four second mounting brackets 27 and the first support frame 11, and connecting the four second guide rods 28 to the two connecting plates 25, the first support frame 11 supports the four second mounting brackets 27. This allows the second mounting brackets 27 and the first support frame 11 to guide the second guide rods 28, enabling the second guide rods 28 to drive the connecting plates 25 to move up and down. By fitting four second limiting plates 29 onto the outside of four second guide rods 28 respectively, fitting a second spring 30 onto the outside of the second guide rods 28, connecting one end of the second spring 30 to the second limiting plate 29, and connecting the other end of the second spring 30 to the second mounting bracket 27, the second mounting bracket 27 supports the second limiting plate 29 and the second guide rod 28 through the second spring 30.

[0049] With the above structure, when the translation mechanism 12 is about to be activated, causing the translation mechanism 12 to move the support plate 13, the connecting plate 25 is pulled down, causing the connecting plate 25 to move the positioning rod 26 downward, thereby causing the positioning rod 26 to move out of the positioning hole 24; at this time, the connecting plate 25 will drive the second guide rod 28 to move downward, thereby causing the second guide rod 28 to press the second spring 30 through the second limiting plate 29, thereby causing the second spring 30 to be in a compressed state. When the support plate 13 moves to its initial position, the connecting plate 25 is released. At this time, the second spring 30 returns to its original position and drives the second guide rod 28, the connecting plate 25, and the positioning rod 26 to move upward, so that the positioning rod 26 fits against the bottom of the positioning seat 23. Then, the support plate 13 continues to move, and the positioning rod 26 and the positioning seat 23 are relatively displaced. When the positioning rod 26 is aligned with the positioning hole 24, the second spring 30 returns to its original position and drives the positioning rod 26 to move upward, so that the positioning rod 26 is embedded in the positioning hole 24, thereby positioning the positioning seat 23 and the support plate 13 to ensure that the clearance groove 18 is aligned with the massage head assembly 17.

[0050] Specifically, a contact switch is installed in the positioning hole 24. The contact switch is electrically connected to the translation mechanism 12 so that when the positioning rod 26 is embedded in the positioning hole 24, the positioning rod 26 can trigger the contact switch, thereby triggering the translation mechanism 12 to stop working.

[0051] In embodiments of the present invention, such as Figures 7 to 10 As shown, the spinal traction device also includes: a second cylinder 31, a connecting rod 32, and a contact plate 33; the two second cylinders 31 are located inside the first support frame 11 and are mounted on the top of the first support frame 11; the connecting rod 32 is connected to the second cylinders 31 and passes through the connecting plate 25; the contact plate 33 is connected to the connecting rod 32 and is located above the connecting plate 25.

[0052] By mounting the second cylinder 31 on top of the first support frame 11, connecting the connecting rod 32 to the second cylinder 31, and allowing the connecting rod 32 to pass through the connecting plate 25, the first support frame 11 supports the second cylinder 31, thereby enabling the second cylinder 31 to drive the connecting rod 32 to move up and down within the connecting plate 25. By connecting the contact plate 33 to the connecting rod 32 and positioning the contact plate 33 above the connecting plate 25, the contact plate 33 and the connecting rod 32 move up and down synchronously, thereby enabling the second cylinder 31 to drive the connecting rod 32 to move up and down within the connecting plate 25. When the moving connecting rod 32 moves downward, it can drive the connecting plate 25 downward through the contact plate 33, thereby enabling the positioning rod 26 to move out of the positioning hole 24 and compressing the second spring 30. At the same time, when the second cylinder 31 drives the connecting rod 32 and the contact plate 33 to move upward, the contact plate 33 disengages from the connecting plate 25, thus avoiding interference between the contact plate 33 and the connecting plate 25 when the reset second spring 30 drives the connecting plate 25 to move upward, thereby improving the user experience of the product.
