[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1

[0021] like Figures 1 to 3As shown, a clutch switching mechanism for manual control between a motor and a lead screw in the first aspect embodiment of this utility model includes a side plate 2, a motor 1 mounted on the side plate 2 with its output shaft passing through the side plate 2 and connected to a drive wheel 3, a lead screw 16 passing through the side plate 2 with a driven wheel 4 mounted at its end, a gap between the drive wheel 3 and the driven wheel 4 for accommodating an intermediate transmission wheel 5, a clutch housing 10 also mounted on the side plate 2, the clutch housing 10 having a U-shaped accommodating cavity, an intermediate transmission shaft 11 transversely passing through the clutch housing 10, a bushing 12 slidably connected to the intermediate transmission shaft 11, an intermediate transmission wheel 5 sleeved and mounted on the outer periphery of the bushing 12, a shift fork 6 passing through and hinged in the top plate of the clutch housing 10, the lower end of the shift fork 6 hinged to the bushing 12, a spring 13 sleeved on the outside of the intermediate transmission shaft 11, one end of the spring 13 abutting against the end face of the bushing 12, and the other end abutting against the inner side of the vertical plate of the clutch housing 10.

[0022] In the above embodiments, it should be noted that, during use, the end of the shift fork 6 is connected to the waist-shaped hole on the bushing 12 through a cylindrical pin, which can move the bushing 12 to slide along the intermediate transmission shaft 11; the spring 13 is used to provide a transmission dimension to cut into the space between the driving wheel 3 and the driven wheel 4 when the teeth switch from disengagement to engagement. Since the intermediate transmission wheel 5 is difficult to cut into smoothly, the lead screw 16 is turned slightly to drive the driven wheel 4 to rotate, and under the action of the spring 13, it can cut into smoothly.

[0023] The technical effect achieved by the above embodiment is as follows: the clutch switching mechanism for manual control between motor lead screw and motor 16 solves the clutch switching problem of gear transmission between motor 1 and lead screw 16. By designing a manually controlled clutch switching mechanism, the separation and engagement of gears between motor 1 and lead screw 16 can be realized more conveniently. After the gears are separated, lead screw 16 can be disengaged from motor resistance, and the position of lead screw 16 can be easily adjusted manually.

[0024] Example 2

[0025] like Figures 1 to 3 As shown, a clutch switching mechanism for manual control between motor leadscrews includes all the contents of Embodiment 1, except that the drive wheel 3 and the output shaft of the motor 1 are connected by a flat key.

[0026] Optionally, the driven wheel 4 and the lead screw 16 are connected by a flat key.

[0027] Optionally, the intermediate drive wheel 5 connecting the bearing is mounted on the outer periphery of the bushing 12.

[0028] The technical effects achieved by the above embodiments are as follows: by adopting a flat key connection, it is convenient to install the drive wheel 3 and the output shaft of the motor 1; at the same time, it is convenient to install the driven wheel 4 and the lead screw 16; by setting bearings, stable rotation of the intermediate transmission wheel 5 on the outer circumference of the bushing 12 is achieved.

[0029] Example 3

[0030] like Figures 1 to 3 As shown, a clutch switching mechanism for manual control between motor leadscrews includes all the contents of Embodiment 2, except that the two ends of the intermediate drive shaft 11 are fixedly connected to the clutch housing 10 by bolts.

[0031] Optionally, it also includes a knob seat 7 fixed to the upper surface of the top plate of the clutch housing 10. A knob plunger 8 is mounted on the side of the knob seat 7. The end of the knob plunger 8 is provided with a pin 9 that passes through the knob seat 7. The pin 9 is used to pass through and fix the position of the shift fork 6.

[0032] Optionally, the shift fork 6 has a pin hole 15 for inserting the pin 9.

[0033] The technical effect achieved by the above embodiment is as follows: the knob plunger 8 is installed on the upper clutch housing 10. When the knob plunger 8 is pulled up, the fork 6 can be moved by hand. When the knob plunger 8 is released, the knob plunger 8 blocks the fork 6. At this time, the intermediate transmission wheel 5 and the bushing 12 cannot slide along the shaft, keeping the intermediate transmission wheel 5 in a disengaged or engaged state.

[0034] Example 4

[0035] like Figures 1 to 3 As shown, a clutch switching mechanism for manual control between motor leadscrews includes all the contents of Embodiment 3, except that the shift fork 6 is mounted in the top plate of the clutch housing 10 via a hinge shaft 14.

[0036] The technical effect achieved by the above embodiment is that by setting the hinge shaft 14, the stable swing of the fork 6 is realized.

[0037] Example 5

[0038] like Figures 1 to 3 As shown, a clutch switching mechanism for manual control between motor leadscrews includes all the contents of Embodiment 4, except that spring 13 is a compression spring.

[0039] Optionally, the driving wheel 3, the driven wheel 4, and the intermediate transmission wheel 5 have the same module.

[0040] The technical effect achieved by the above embodiments is that the above settings ensure the stable operation of the device.

[0041] The working principle of the above embodiments is as follows:

[0042] Switching from disengaged to engaged state: Pull up the knob plunger 8. At this time, the shift fork 6 is released, the spring 13 presses the bushing 12 to the left, and the bushing 12 drives the intermediate transmission wheel 5 to slide to the left along the intermediate transmission shaft 11. Gently rotate the lead screw 16 to drive the driven wheel 4 to rotate. When the intermediate transmission wheel 5 is rotated to a suitable angle, the knob plunger 8 is released, and the pin 9 is inserted into the pin hole 15 in the middle of the shift fork 6 to restrict the position of the shift fork 6, thereby restricting the position of the intermediate transmission wheel 5, realizing the power transmission between the motor 1 and the lead screw 16.

[0043] Switching from engaged to disengaged state: Pull up the knob plunger 8, at which point the shift fork 6 is released. Pull the shift fork 6 by hand from the top to the left, causing the shift fork 6 to drive the intermediate transmission wheel 5 to slide to the right along the intermediate transmission shaft 11. The gears are disengaged. At this point, release the knob plunger 8, and the shift fork 6 is fixed in position. With the gears in the disengaged state, power transmission is cut off, allowing the lead screw 16 to be easily adjusted.
