After the inspection is completed, the safety box 4 can also be quickly installed.

[0030] Embodiment 2

[0031] The main difference from the first embodiment is:

[0032] A screw-type stepping linear motor, the heat dissipation mechanism 5 includes a cross plate 51 installed on the right side of the inner wall of the safety box 4, a driving motor 52 is installed on the left side of the cross plate 51, the driving motor 52 is connected to the external circuit through wires, one end of the output shaft of the driving motor 52 is fixedly connected to a fan 53, the inner wall of the safety box 4 is fixedly connected to multiple groups of buffer springs 7, one end of the buffer spring 7 is fixedly connected to a buffer plate 8, a heat dissipation mesh plate 9 is installed on the right side of the safety box 4, and the heat dissipation mesh plate 9 is installed on the right side of the safety box 4 through bolts, a limiting plate 10 is installed at the bottom of the safety box 4, a limiting groove 11 is provided on the right side of the top of the bottom plate 1, the limiting plate 10 and the limiting groove 11 are both convex, the inner surface of the limiting groove 11 is slidably connected to the surface of the limiting plate 10, one end of the output shaft of the stepping motor 3 is fixedly connected to a screw rod 12 through a coupling, and the surface of the screw rod 12 is threadedly connected to a nut mounting seat 13 through a sliding nut. The sliding nut is installed inside the nut mounting seat 13, the screw rod 12 is connected to the internal thread of the sliding nut, a slide rail 14 is installed on the top of the base plate 1, and the surface of the slide rail 14 is slidably connected to the bottom of the nut mounting seat 13, a pointer plate 15 is installed on one side of the nut mounting seat 13, and a scale plate 16 is installed on the left side of the support plate 2. The scale plate 16 and the pointer plate 15 are used to record the moving distance of the nut mounting seat 13, and the inside of the pointer plate 15 is slidably connected to the surface of the scale plate 16. By providing a heat dissipation mechanism 5, rapid heat dissipation inside the safety box 4 is achieved to avoid overheating and damage of the stepping motor 3 under long-term operation. By providing a buffer plate 8 and a buffer spring 7, when the safety box 4 is subjected to external impact, the external impact force can be buffered by the buffer plate 8 and the buffer spring 7. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When in use, the limiting plate 10 at the bottom of the safety box 4 is slid to the inner surface of the limiting groove 11, so that the left side of the safety box 4 slides to the inside of the notch on the right side of the support plate 2. At this time, the bottom of the clamping block 613 slides on the oblique groove surface at the top of the fixing block 621. When the clamping block 613 slides, the control rod 612 slides upward, and the installation spring 614 begins to contract. When the clamping block 613 slides to the inner surface of the clamping groove 622, the installation spring 614 is not affected by external forces, so that the clamping block 613 is clamped with the inner surface of the clamping groove 622, thereby realizing the rapid installation of the safety box 4. At the same time, during the installation of the safety box 4, the inclined surface of the bottom left side of the buffer plate 8 is attached to and slides with the surface of the stepping motor 3, and under the influence of the elasticity of the buffer spring 7 Under the impact, the buffer plate 8 fits the surface of the stepper motor 3. When the safety box 4 is subjected to external impact, the external impact force can be buffered by the buffer plate 8 and the buffer spring 7, so as to protect the internal stepper motor 3. When the stepper motor 3 is working, it drives the screw rod 12 to rotate. The rotation of the screw rod 12 makes the sliding nut and the nut mounting seat 13 slide synchronously. The nut mounting seat 13 slides on the surface of the slide rail 14, thereby driving the pointer plate 15 to slide on the surface of the scale plate 16, so as to observe the moving distance of the nut mounting seat 13. At the same time, when the stepper motor 3 is working, the fan 53 is driven to rotate by starting the drive motor 52. The fan 53 dissipates the heat inside the safety box 4 from the heat dissipation mesh plate 9 to avoid overheating and damage of the stepper motor 3 when it works for a long time.
