[0038] Embodiment three

[0039] As shown in Figures 1-5 Compared with embodiment one, the embodiment further comprises that the inner part of the outer screw 7 is provided with a friction assembly 8, the friction assembly 8 is used for increasing the rotational friction between the screw cylinder 6 and the outer screw 7, the friction assembly 8 is composed of an inner screw 801, a sliding cavity 802, a friction block 803 and a tapered head 804, the sliding cavity 802 is arranged on the inner wall of the outer screw 7, the friction block 803 is slidably arranged on the sliding cavity 802 at equal intervals, the inner screw 801 is provided with threads in the sliding cavity 802, and the tapered head 804 is rotatably arranged at the bottom end of the inner screw 801, the taper surface of the tapered head 804 is matched with the inclined surface of each friction block 803, the inner screw 801 is fixed in the sliding cavity 802 through threaded connection, so as to ensure that the inner screw 801 and the outer screw 7 have precise threaded engagement, when the inner screw 801 rotates, it drives the tapered head 804 to move axially along the inner screw 801. The taper surface of the tapered head 804 and the inclined surface of each friction block 803 are matched, so that when the inner screw 801 rotates, the tapered head 804 gradually moves downwards, thereby forcing the friction block 803 to slide out and abut against the inner wall of the outer screw 7, and forming pressure on the inner wall of the screw cylinder 6.

[0040] Through the action of this mechanical device, the friction block 803 is quickly slipped out under the pressure of the cone head 804, tightly contacts and presses the inner wall of the screw cylinder 6, and further increases the friction force between the outer screw rod 7 and the screw cylinder 6. The increase of the friction force effectively avoids the self-rotation phenomenon of the outer screw rod 7 due to the rotational inertia or excessive pressure in the heavy load state, thereby ensuring the high efficiency and stability of the equipment.

[0041] In addition, the design of the friction assembly 8 also has a certain self-adjusting ability, and the friction force can be adjusted with the change of the load, thereby avoiding the wear or overheating caused by excessive friction, and further prolonging the service life of the equipment.

[0042] The positioning rod 9 is threadedly arranged on the foot disc 5, and the positioning rod 9 limits the movement trajectory of the moving assembly 4. Manual rotation of the positioning rod 9 makes the positioning rod 9 downwardly abut against the upper surface of the screw seat 401, and the positioning rod 9 limits the upward movement of the screw seat 401, thereby avoiding the self-rotation phenomenon of the screw seat 401 on the screw cylinder 6 under heavy pressure.

[0043] The friction assembly 8 not only enhances the working stability by increasing the friction force, but also has durability and self-adjusting ability, so as to ensure that the cooperation between the outer screw rod 7 and the screw cylinder 6 is always efficient and stable in a complex working environment, thereby improving the performance of the equipment, and avoiding premature component damage and excessive wear.

[0044] It should be noted that the structure of the electromagnet 14 adopts the current mature technology, and its working principle and internal structure are widely known in the technical field. As a common electrical driving element, the basic principle and design of the electromagnet 14 have been widely applied, so in the utility model, the specific structure and working mode of the electromagnet 14 do not involve any innovation or improvement. The utility model only uses the conventional function of the electromagnet 14 to achieve the required driving or control effect, without modifying or optimizing the internal structure.
