an elastic wire protecting sleeve (25) is arranged on one side, away from the end part of the flat cable (2), of the mounting seat (23), and the wire protecting sleeve (25) is used for reducing excessive deformation of the part, close to the end part, of the flat cable (2) and reducing the probability of breakage of the part, close to the end part, of the flat cable (2) when the flat cable (2) is repeatedly bent; the thickness of the wire protecting sleeve (25) is gradually reduced along the direction far away from the mounting seat (23), so that the moving space is reduced when the flat cable (2) is bent;
a group of air holes (26) are uniformly formed in the protecting sleeve (21), one end of each air hole (26) is communicated with the flat cable (2), the other end of each air hole (26) is communicated with a group of lubricating cavities (27), talcum powder is filled in each lubricating cavity (27), and the lubricating cavities (27) overflow the talcum powder to reduce abrasion between the flat cable (2) and the protecting sleeve (21) and further prolong the service life of the flat cable (2); an elastic air blowing chamber (28) is arranged at one end of the air hole (26) far away from the flat cable (2), air is sprayed out through the air blowing chamber (28) to drive the talcum powder to be uniformly dispersed on the surface of the flat cable (2), and abrasion between the flat cable (2) and the protective sleeve (21) is further reduced;
when the air valve is controlled to work, the air cylinder (14) is inflated or deflated, and when a rodless cavity of the air cylinder (14) is inflated, the hanging column (16) and the hook (17) are fixed on the support frame (11) and are not moved, so that a piston rod of the air cylinder (14) stretches out and then pushes the moving rod (13) to slide in the guide cylinder (12), and further the machine body (1) is driven to move downwards and then reduce the height; when a rod cavity of the air cylinder (14) is inflated, a piston rod of the air cylinder (14) contracts towards the inside of the air cylinder (14) and further pulls the moving rod (13), so that the guide cylinder (12) is communicated with the machine body (1) to move upwards, the height of the machine body (1) is finally increased, and the quick adjustment of the height of the machine body (1) is further realized through the air cylinder (14); the elasticity of the flat cable (2) can be further increased through the protective sleeve (21) nested on the periphery of the flat cable (2), so that when the machine body (1) is prevented from sliding up and down relative to the support frame (11), because the two ends of the flat cable (2) are respectively electrically connected with the machine body (1) and the buckle on the support frame (11), the elasticity of the protective sleeve (21) can be further increased through the elastic steel wire (22) axially arranged along the protective sleeve, the protective sleeve (21) is prevented from being excessively bent, the flat cable (2) is further bent and deformed within the elastic range, and the bending and breaking of the flat cable (2) are reduced; because the body (1) has relative displacement relative to the support frame (11) when adjusting the height, the two ends of the protective sleeve (21) need to use the pressing sheets to fix the flat cable (2), the flat cable (2) is prevented from loosening with the buckle when moving along with the body (1), and further poor contact is caused, the flat cable (2) is reliably fixed and cannot be crushed by the pressing sheets through the support of the steel bar (24) matching with the mounting seat (23), because the two ends of the flat cable (2) are respectively electrically connected with the buckle on the body (1) and the support frame (11), the partial bending degree of the flat cable (2) close to the buckle is maximum when the body (1) moves up and down, at the moment, the partial bending radius of the flat cable (2) close to the buckle can be increased through the elastic wire protective sleeve (25), the flat cable (2) is ensured not to be broken due to excessive bending, and simultaneously, the thickness of the wire protective sleeve (25) is gradually reduced along the direction far away from the mounting seat, so that the flat cable (2) can not encroach on the inner space of the machine body (1) too much under the action of the wire sheath (25) when being bent; when the flat cable (2) drives the protecting sleeve (21) to be continuously bent, the talcum powder in the lubricating cavity (27) enters a gap between the protecting sleeve (21) and the flat cable (2) from the air hole (26), so that the abrasion of the flat cable (2) by the protecting sleeve (21) is reduced, meanwhile, the wire protecting sleeve (25) is bent, so that the air blowing chamber (28) is compressed, and after the generated compressed air is blown out from the air hole (26), the diffusion area and the diffusion uniformity of the talcum powder in the gap between the protecting sleeve (21) and the flat cable (2) are further increased, and the friction between the flat cable (2) and the protecting sleeve (21) is further reduced.
