具体实施方式Detailed ways
为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的技术方案进行清楚、完整的描述，显然，所描述的实施例是本发明的部分实施例，而不是全部实施例。基于本发明的实施例，本领域普通技术人员在没有付出创造性劳动的前提下所获得的所有其他实施例，都属于本发明 的保护范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, a clear and complete description will be made below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, and Not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without any creative effort fall within the protection scope of the present invention.
本发明较佳实施例如图1至图2所示，提供一种血栓弹力图仪混匀机构，包括：用于夹持试管6的夹持组件2、用于驱动夹持组件2向试管6方向移动的第一驱动组件1，以及用于驱动夹持组件2脱离第一驱动组件1的第二驱动组件3；混匀时，第一驱动组件1驱动夹持组件2夹紧试管6后，夹持组件2在第二驱动组件3的驱动下向远离第一驱动组件1的方向移动，并在到达指定位置时被第二驱动组件3带动翻转，使试管6被翻转，实现混匀。A preferred embodiment of the present invention, as shown in Figures 1 to 2, provides a thromboelastography apparatus mixing mechanism, including: a clamping assembly 2 for clamping a test tube 6, and for driving the clamping assembly 2 to the direction of the test tube 6 The moving first driving assembly 1, and the second driving assembly 3 used to drive the holding assembly 2 to break away from the first driving assembly 1; when mixing, the first driving assembly 1 drives the holding assembly 2 to clamp the test tube 6, and then clamps The holding assembly 2 is driven by the second driving assembly 3 to move away from the first driving assembly 1, and when it reaches the specified position, it is turned over by the second driving assembly 3, so that the test tube 6 is turned over to achieve mixing.
第一驱动组件1驱动夹持组件2进行水平方向的运动，第二驱动组件3驱动夹持组件2进行竖直方向的运动。摇匀时，第一驱动组件1驱动夹持组件2向试管6方向移动并将试管架7上的试管6卡入夹持组件2中。夹紧试管6后，第二驱动组件3驱动夹持组件2向远离第一驱动组件1的方向移动(即上升)，使得夹持组件2脱离第一驱动组件1的控制，在此过程中，试管6随夹持组件2上升而脱离试管架7。在夹持组件2带动试管6继续上升至指定高度时，夹持组件2会被第二驱动组件3带动旋转，进而使得试管6被翻转，多次重复旋转过程，使得夹持组件2上的试管6被多次翻转，实现混匀。The first driving assembly 1 drives the clamping assembly 2 to move horizontally, and the second driving assembly 3 drives the clamping assembly 2 to move vertically. When shaking well, the first driving assembly 1 drives the clamping assembly 2 to move toward the test tube 6 and snaps the test tube 6 on the test tube rack 7 into the clamping assembly 2 . After clamping the test tube 6, the second driving assembly 3 drives the clamping assembly 2 to move (i.e. rise) away from the first driving assembly 1, so that the clamping assembly 2 breaks away from the control of the first driving assembly 1. In the process, The test tube 6 is separated from the test tube rack 7 as the clamping assembly 2 rises. When the clamping assembly 2 drives the test tube 6 to continue to rise to the specified height, the clamping assembly 2 will be rotated by the second driving assembly 3, and then the test tube 6 will be turned over, and the rotation process will be repeated many times, so that the test tube on the clamping assembly 2 6 was turned over several times to achieve mixing.
在一定高度范围内，夹持组件2受第一驱动组件1的驱动进行往复运动，以夹持或松开试管6。当夹持组件2受第二驱动组件3的驱动上升至更高的高度时，夹持组件2脱离第一驱动组件1的控制，并在到达指定高度时实现旋转，整个过程中第一驱动组件1不随夹持组件2旋转，因此混匀机构中电缆没有被反复弯折，可靠性高。第一驱动组件1、第二驱动组件3与夹持组件2之间紧密配合，结构紧凑且分布合理，体积小，节省了混匀机构的安装空间，动力源数量少，结构简单，成本低。Within a certain height range, the clamping assembly 2 is driven by the first driving assembly 1 to reciprocate, so as to clamp or release the test tube 6 . When the clamping assembly 2 is driven by the second drive assembly 3 to rise to a higher height, the clamping assembly 2 breaks away from the control of the first drive assembly 1, and realizes rotation when reaching a specified height, and the first drive assembly during the whole process 1 does not rotate with the clamping assembly 2, so the cables in the mixing mechanism are not repeatedly bent, and the reliability is high. The first driving assembly 1 , the second driving assembly 3 and the clamping assembly 2 are closely matched, the structure is compact and the distribution is reasonable, the volume is small, the installation space of the mixing mechanism is saved, the number of power sources is small, the structure is simple, and the cost is low.
在进一步的实施例中，血栓弹力图仪混匀机构还包括底座4；第一驱动组 件1包括：设置在底座4一端的第一动力件11、与第一动力件11连接的第一滑动座12，以及用于连接底座4与第一滑动座12的第一滑行件。In a further embodiment, the thromboelastography apparatus mixing mechanism also includes a base 4; the first drive assembly 1 includes: a first power member 11 arranged at one end of the base 4, and a first sliding seat connected to the first power member 11 12, and the first sliding member for connecting the base 4 and the first sliding seat 12.
第一滑行件为设置在底座4上的第一导轨14，以及设置在第一导轨14上且与第一滑动座12连接的第一滑块13。The first sliding member is a first guide rail 14 arranged on the base 4 , and a first slider 13 arranged on the first guide rail 14 and connected to the first sliding seat 12 .
第一滑动座12与第一滑块13之间机械连接，当第一滑动座12受到第一动力件11的驱动时，第一滑动座12带动第一滑块13沿第一导轨14进行直线滑行。The mechanical connection between the first sliding seat 12 and the first sliding block 13, when the first sliding seat 12 is driven by the first power member 11, the first sliding seat 12 drives the first sliding block 13 to move along the first guide rail 14 in a straight line slide.
在进一步的实施例中，第一滑动座12上设有凹槽121；夹持组件2包括第二滑动座21，以及设置在第二滑动座21侧边的第一从动件22；第一从动件22可分离的设置在凹槽121中。其中，第一从动件22为轴承。In a further embodiment, a groove 121 is provided on the first sliding seat 12; the clamping assembly 2 includes a second sliding seat 21, and a first follower 22 arranged on the side of the second sliding seat 21; the first The follower 22 is detachably disposed in the groove 121 . Wherein, the first follower 22 is a bearing.
在进一步的实施例中，夹持组件2还包括夹爪23，以及用于对夹爪23施加夹持力的施力件；夹爪23首端铰接在第二滑动座21上；夹爪23末端可受迫打开，并在施力件的驱动下自动合拢，以夹持试管6。其中，施力件为弹簧24。In a further embodiment, the clamping assembly 2 also includes a clamping jaw 23, and a force applying member for applying a clamping force to the clamping jaw 23; the head end of the clamping jaw 23 is hinged on the second sliding seat 21; the clamping jaw 23 The end can be forced to open, and automatically closes under the drive of the force applying member to clamp the test tube 6 . Wherein, the forcing member is a spring 24 .
待机状态下，第一从动件22处于凹槽121中，凹槽121顶部设有开口。通过凹槽121与第一从动件22配合，使得第一滑动座12对第二滑动座21形成约束，用于带动第二滑动座21随其共同进行往复移动。In the standby state, the first follower 22 is located in the groove 121 , and the top of the groove 121 is provided with an opening. The groove 121 cooperates with the first follower 22 , so that the first sliding seat 12 constrains the second sliding seat 21 , and is used to drive the second sliding seat 21 to reciprocate together with it.
在待机状态转变为夹紧试管状态过程中，在第一动力件11的驱动下，第一滑动座12与第一滑块13沿第一导轨14向靠近试管6的方向移动，第二滑动座21被第一滑动座12带动共同向靠近试管6的方向移动。在夹爪23末端接触到试管架7上的试管6时，第一动力件11持续驱动第一滑动座12，进而使得夹爪23获得一个持续向试管6移动的推力。由于夹爪23末端受迫会打开，试管架7的位置完全固定，试管6被强行卡入夹爪23中，而夹爪23自身又受 弹簧24的作用被拉回合拢，弹簧24对试管6施加夹持力，夹紧试管6。此时第一滑块13到达第一导轨14末端，第一动力件11停止驱动第一滑动座12。During the transition from the standby state to the state of clamping the test tube, under the drive of the first power member 11, the first sliding seat 12 and the first sliding block 13 move along the first guide rail 14 toward the direction close to the test tube 6, and the second sliding seat 21 is driven by the first sliding seat 12 to move towards the direction close to the test tube 6 together. When the end of the jaw 23 touches the test tube 6 on the test tube rack 7 , the first power member 11 continuously drives the first sliding seat 12 , so that the jaw 23 obtains a thrust to continuously move towards the test tube 6 . Because the ends of the jaws 23 are forced to open, the position of the test tube rack 7 is completely fixed, and the test tube 6 is forcibly snapped into the jaws 23, and the jaws 23 themselves are pulled back by the action of the spring 24. Apply clamping force to clamp the test tube 6. At this time, the first sliding block 13 reaches the end of the first guide rail 14 , and the first power member 11 stops driving the first sliding seat 12 .
其中，夹爪23由两个铰接在第二滑动座21上且对称设置的夹片构成，夹片靠近试管6的一端均设有倒角，夹片通过铰链转轴铰接在第二滑动座21上。弹簧24两端分别连接两侧的夹片，且夹片上下均设有上述弹簧24。当夹爪23末端受迫时，两侧的夹片会以不同的转动方向转动，即打开，此时弹簧24被拉伸产生弹力，会将打开的夹爪23拉回合拢。通过设置倒角，夹爪23末端形成一个开口，使得试管6更容易被卡入夹爪23中。Wherein, the jaws 23 are composed of two symmetrically arranged clips hinged on the second sliding seat 21. The ends of the clips near the test tube 6 are provided with chamfers, and the clips are hinged on the second sliding seat 21 through the hinge shaft. . The two ends of the spring 24 are respectively connected to the clips on both sides, and the above-mentioned springs 24 are arranged above and below the clip. When the ends of the jaws 23 are forced, the clips on both sides will rotate in different directions, that is, they will be opened. At this time, the spring 24 will be stretched to generate elastic force, which will pull the opened jaws 23 together. By setting the chamfer, an opening is formed at the end of the clamping jaw 23 , so that the test tube 6 is more easily snapped into the clamping jaw 23 .
当试管6放回试管架7上时，通过第一动力件11反向驱动第一滑动座12滑动，进而带动第二滑动座21与夹爪23反方向移动，夹爪23末端受到第一动力件11的反向推力并在试管架7的作用下，受迫打开，使得夹持在夹爪23上的试管6脱离夹爪23。When the test tube 6 is put back on the test tube rack 7, the first sliding seat 12 is reversely driven to slide by the first power part 11, and then the second sliding seat 21 is driven to move in the opposite direction with the clamping jaw 23, and the end of the clamping jaw 23 is subjected to the first power 11 and under the action of the test tube rack 7, it is forced to open, so that the test tube 6 clamped on the jaws 23 breaks away from the jaws 23.
在另一实施例中，轴承与凹槽121的配合也可以替换为其它能对第二滑动座21及夹爪23构成约束的部件，该部件能够实现在一定高度范围内带动第二滑动座21及夹爪23相对于试管6进行往复运动，以及在上升至一定高度范围时能够使第二滑动座21与第一滑动座12分离即可。In another embodiment, the cooperation between the bearing and the groove 121 can also be replaced by other components that can constrain the second sliding seat 21 and the jaws 23, and this component can drive the second sliding seat 21 within a certain height range. And the jaws 23 reciprocate relative to the test tube 6, and the second sliding seat 21 can be separated from the first sliding seat 12 when it rises to a certain height range.
在另一实施例中，施力件可以使用其它能够储存能量的结构代替，例如磁铁，气囊等。In another embodiment, the force applying member can be replaced by other structures capable of storing energy, such as magnets, air bags and the like.
在另一实施例中，夹爪可以采用类似于簧片的结构，采用该结构无需设置施力件与铰接转轴也可以实现受迫打开和自动合拢的过程。In another embodiment, the jaws may adopt a structure similar to that of a reed, and the process of forced opening and automatic closing can also be realized without setting a force applying member and a hinged shaft by using this structure.
在进一步的实施例中，血栓弹力图仪混匀机构还包括设置在底座4上的机架5；第二驱动组件3包括：设置在机架5一端的第二动力件31、与第二动力件31连接的第三滑动座32，以及用于连接第三滑动座32与机架5的第二滑 行件。第二滑行件为设置在机架5上的第二导轨34，以及设置在第二导轨34上且与第三滑动座32连接的第二滑块33。In a further embodiment, the thromboelastography apparatus mixing mechanism also includes a frame 5 arranged on the base 4; the second drive assembly 3 includes: a second power member 31 arranged at one end of the frame 5, and a second power The third sliding seat 32 connected with the member 31, and the second sliding member for connecting the third sliding seat 32 and the frame 5. The second sliding member is a second guide rail 34 arranged on the frame 5 , and a second slider 33 arranged on the second guide rail 34 and connected to the third sliding seat 32 .
第三滑动座32在第二动力件31的驱动下，通过第二滑块33沿第二导轨34直线上升或下降。Driven by the second power member 31 , the third slide seat 32 rises or falls linearly along the second guide rail 34 through the second slide block 33 .
在进一步的实施例中，第三滑动座32上设有转轴321；第二驱动组件3还包括设置在转轴321上的旋转座35；旋转座35与第二滑动座21之间通过第三滑行件连接。第三滑行件为设置在第二滑动座21上的第三导轨25；旋转座35通过滑块连接在第三导轨25上。In a further embodiment, a rotating shaft 321 is provided on the third sliding seat 32; the second drive assembly 3 also includes a rotating seat 35 arranged on the rotating shaft 321; file connection. The third sliding member is the third guide rail 25 arranged on the second sliding seat 21 ; the rotating seat 35 is connected to the third guide rail 25 through the slider.
旋转座35可绕转轴321转动，其径向移动被限制。第二滑动座21通过第三导轨25与旋转座35连接，在第一动力件11的驱动下，第二滑动座21与第三导轨25可在旋转座35上水平滑动。The rotating seat 35 can rotate around the rotating shaft 321, and its radial movement is restricted. The second sliding base 21 is connected to the rotating base 35 through the third guide rail 25 , driven by the first power member 11 , the second sliding base 21 and the third guiding rail 25 can slide horizontally on the rotating base 35 .
在进一步的实施例中，机架5上设有滑行槽51；滑行槽51远离底座4一端向一侧弯曲扩展；旋转座35上设有连接块36，以及设置在连接块36上的第二从动件37；第二从动件37末端***在滑行槽51中。其中，第二从动件37在滑行槽51内的部分安装有轴承。In a further embodiment, the frame 5 is provided with a sliding groove 51; the sliding groove 51 is bent and expanded to one side away from the end of the base 4; the rotating base 35 is provided with a connecting block 36, and a second The follower 37 ; the end of the second follower 37 is inserted in the sliding groove 51 . Wherein, the part of the second follower 37 inside the sliding groove 51 is installed with a bearing.
滑行槽51可以分为直线段与弯曲段，其中，弯曲段与第二从动件37构成直线凸轮机构。当第二从动件37处于直线段时，由于凹槽121与第一从动件22的配合，旋转座35受到第二从动件37与第二滑动座21的限制，不发生旋转。当第二从动件37从弯曲段的起点移动弯曲段的终点时，凹槽121与第一从动件22已经脱离，旋转座35在第三滑动座32与弯曲段轨迹的共同作用下发生旋转，进而带动第二滑动座21共同旋转，使得第二滑动座21上夹爪23夹持的试管6被翻转。在第二动力件31的驱动下，第二从动件37在弯曲段起点与终点之间进行重复移动，夹爪23上夹持的试管6被多次翻转，实现混匀。The sliding groove 51 can be divided into a straight section and a curved section, wherein the curved section and the second follower 37 form a linear cam mechanism. When the second follower 37 is in the straight line, due to the cooperation between the groove 121 and the first follower 22 , the rotating seat 35 is restricted by the second follower 37 and the second sliding seat 21 , and does not rotate. When the second follower 37 moves from the starting point of the curved section to the end point of the curved section, the groove 121 and the first follower 22 have disengaged, and the rotating seat 35 is formed under the joint action of the third sliding seat 32 and the track of the curved section. Rotate, and then drive the second sliding seat 21 to rotate together, so that the test tube 6 clamped by the jaws 23 on the second sliding seat 21 is turned over. Driven by the second power member 31, the second follower 37 repeatedly moves between the starting point and the end point of the bending section, and the test tube 6 held by the jaws 23 is turned over several times to realize mixing.
在进一步的实施例中，第一动力件11与第二动力件31均为丝杆电机。第一动力件11与第二动力件31通过螺母分别与第一滑动座12以及第三滑动座32配合，用于驱动第一滑动座12与第三滑动座32分别进行往复运动。In a further embodiment, both the first power member 11 and the second power member 31 are screw motors. The first power member 11 and the second power member 31 cooperate with the first sliding seat 12 and the third sliding seat 32 respectively through nuts, and are used to drive the first sliding seat 12 and the third sliding seat 32 to reciprocate respectively.
在进一步的实施例中，旋转座35与第二滑动座21上分别设有位置相对应的磁铁。当夹爪23夹紧试管6时，两个磁铁相互吸引，对第二滑动座21的位置进行限制，防止后续旋转座35转动时，第二滑动座21在转动过程中出现随意移动的情况。In a further embodiment, the rotating base 35 and the second sliding base 21 are respectively provided with corresponding magnets. When the jaws 23 clamp the test tube 6, the two magnets attract each other to limit the position of the second sliding seat 21, preventing the second sliding seat 21 from moving arbitrarily during the rotation when the subsequent rotating seat 35 is rotated.
在本实施例中，如图3至图6所示，摇匀机构的运行过程如下：In this embodiment, as shown in Figures 3 to 6, the operation process of the shaking mechanism is as follows:
待机状态转变为夹紧试管状态时，第一动力件11驱动第一滑动座12带动第一滑块13沿第一导轨14向靠近试管6方向滑动，第二滑动座21在凹槽121与第一从动件22的作用下随第一滑动座12共同滑动，在夹爪23接触到试管6时，第一动力件11持续驱动，使得夹爪23末端被挤压打开，强行将试管6卡入夹爪23中，并且在弹簧24的作用下自动合拢，夹紧试管6。此时第一动力件11停止驱动。在夹紧试管6后，第二动力件31启动驱动第三滑动座32带动第二滑块33沿第二导轨34上升，第二从动件37沿滑行槽51直线段上升，在此过程中，第一从动件22脱离凹槽121，第二滑动座21不受第一滑动座12的控制。当第二从动件37到达滑行槽51弯曲段的起点时，混匀机构进入混匀状态，第二动力件31继续驱动第三滑动座32上升，第二从动件37从滑行槽51弯曲段的起点滑向终点，旋转座35在第二从动件37的带动下转动，使得第二滑动座21随旋转座35共同转动，夹爪23上的试管6被翻转。当第二从动件37到达滑行槽51弯曲段的终点时，第二动力件31反向驱动第三滑动座32，使得第二从动件37从滑行槽51弯曲段的终点滑行到起点，试管6恢复原朝向。在第二动力件31的驱动件，第二从动件37在滑行槽51弯曲段的起点、 终点两个状态间切换数次，使得试管6翻转数次，从而完成混匀。完成混匀后，混匀机构回到夹紧试管状态，第二动力件31反向驱动第三滑动座32下降，进而带动夹爪23与试管6下降，试管6被重新插回试管架7上，第一从动件22进入凹槽121中。第一动力件11反向驱动，使得夹爪23受迫打开，夹爪23上的试管6脱离夹爪23，混匀机构回到待机状态，混匀工作完成。When the standby state changes to the state of clamping the test tube, the first power member 11 drives the first sliding seat 12 to drive the first sliding block 13 to slide along the first guide rail 14 towards the test tube 6, and the second sliding seat 21 is in the groove 121 and the second sliding seat 21. Under the action of a follower 22, it slides together with the first sliding seat 12. When the jaw 23 touches the test tube 6, the first power member 11 continues to drive, so that the end of the jaw 23 is squeezed open, and the test tube 6 is forcibly clamped. into the jaws 23, and automatically closed under the action of the spring 24, to clamp the test tube 6. At this time, the first power member 11 stops driving. After clamping the test tube 6, the second power member 31 starts to drive the third sliding seat 32 to drive the second slider 33 to rise along the second guide rail 34, and the second follower 37 rises along the straight line of the sliding groove 51. During this process , the first follower 22 breaks away from the groove 121 , and the second sliding seat 21 is not controlled by the first sliding seat 12 . When the second follower 37 reaches the starting point of the curved section of the sliding groove 51, the mixing mechanism enters the mixing state, the second power member 31 continues to drive the third sliding seat 32 to rise, and the second follower 37 bends from the sliding groove 51 The starting point of the section slides to the end point, and the rotating seat 35 rotates under the drive of the second follower 37, so that the second sliding seat 21 rotates together with the rotating seat 35, and the test tube 6 on the jaws 23 is turned over. When the second follower 37 reaches the end point of the curved section of the sliding groove 51, the second power member 31 reversely drives the third sliding seat 32, so that the second follower 37 slides from the end point of the curved section of the sliding groove 51 to the starting point, Test tube 6 returns to its original orientation. In the driving part of the second power part 31, the second follower 37 switches several times between the start point and the end point of the curved section of the sliding groove 51, so that the test tube 6 turns over several times, thereby completing the mixing. After the mixing is completed, the mixing mechanism returns to the state of clamping the test tube, the second power part 31 reversely drives the third sliding seat 32 to descend, and then drives the jaw 23 and the test tube 6 to descend, and the test tube 6 is reinserted on the test tube rack 7 , the first follower 22 enters the groove 121 . The first power part 11 is reversely driven, so that the jaws 23 are forced to open, the test tube 6 on the jaws 23 breaks away from the jaws 23, the mixing mechanism returns to the standby state, and the mixing work is completed.
上述第一动力件11与第二动力件31在指定位置切换状态，可以通过控制丝杆电机的行程或在对应位置设置感应装置感应实现。The above-mentioned first power member 11 and the second power member 31 switch states at a specified position, which can be realized by controlling the stroke of the screw motor or installing an induction device at a corresponding position.
在本方案中，在待机状态转变为夹紧试管状态时，第二滑动座21与夹爪23受到第一驱动组件1的控制。在夹紧试管状态变为混匀状态时，第二滑动座21与夹爪23在第二动力件31的驱动下脱离第一驱动组件1的控制，也就是说，试管6在混匀过程中，第一动力件11与第二动力件31不会随旋转座35及第二滑动座21共同旋转，因此混匀机构中的电缆没有被反复弯折，可靠性高。在待机状态转变为混匀状态的过程中，各部件之间紧密配合，结构紧凑且分布合理，混匀机构的体积小，节省了其安装空间。且仅通过第一动力件11与第二动力件31两个动力源便可完成整个混匀过程，动力源数量少，成本低。In this solution, when the standby state changes to the clamping test tube state, the second sliding seat 21 and the clamping jaws 23 are controlled by the first driving assembly 1 . When the state of clamping the test tube changes to the state of mixing, the second sliding seat 21 and the jaw 23 are driven by the second power member 31 to break away from the control of the first drive assembly 1, that is to say, the test tube 6 is in the mixing process , the first power member 11 and the second power member 31 will not rotate together with the rotating seat 35 and the second sliding seat 21, so the cables in the mixing mechanism are not repeatedly bent, and the reliability is high. In the process of changing from the standby state to the mixing state, the components are closely matched, the structure is compact and the distribution is reasonable, and the volume of the mixing mechanism is small, which saves its installation space. And the whole mixing process can be completed only by the two power sources of the first power part 11 and the second power part 31 , the number of power sources is small, and the cost is low.
在另一实施例中，第一动力件11与第二动力件31也可以采用气缸代替。In another embodiment, the first power member 11 and the second power member 31 may also be replaced by air cylinders.
在另一实施例中，第二从动件37也可以是一根杆，能够与滑行槽51弯曲段构成直线凸轮机构。In another embodiment, the second follower 37 can also be a rod, which can form a linear cam mechanism with the curved section of the sliding groove 51 .
在另一实施例中，第二从动件37与滑行槽51弯曲段可以采用断续运作的连杆替代，即第二滑动座21与夹爪23在一定高度之下不被旋转座35带动旋转，当其上升至指定高度时会被旋转座35带动自动旋转。In another embodiment, the curved section of the second follower 37 and the sliding groove 51 can be replaced by an intermittently operating connecting rod, that is, the second sliding seat 21 and the clamping jaw 23 are not driven by the rotating seat 35 below a certain height Rotate, when it rises to the specified height, it will be driven by the swivel seat 35 to rotate automatically.
在另一实施例中，第一滑行件、第二滑行件与第三滑行件可以采用光轴与 轴套的结构替代。In another embodiment, the first sliding member, the second sliding member and the third sliding member may be replaced by a structure of an optical shaft and a shaft sleeve.
