Body-size-adjustable dressmaker form

A body-size-adjustable dressmaker form, comprising a central-support adjusting system, a neck adjusting system, a chest adjusting system, a waist adjusting system, a hip adjusting system, an arm adjusting system, a base and an upper-body outer housing, wherein

• the chest adjusting system, the waist adjusting system and the hip adjusting system each comprises a multi-axis synchronous co-directional adjusting device and an adjusting knob;
• the central-support adjusting system comprises an upper-body support assembly and a lower-body support assembly, wherein the upper-body support assembly is provided with mounting positions adapted to the multi-axis synchronous co-directional adjusting devices;
• each of the multi-axis synchronous co-directional adjusting devices comprises a fixed frame and a plurality of adjusting components each mounted on the fixed frame, wherein each of the plurality of adjusting components comprises a bevel gear, a telescopic structural member and a transmission rod connecting the bevel gear with the telescopic structural member;
• the bevel gears are arranged to circle an outer wall of the upper-body support assembly in the fixed frame, and any two adjacent bevel gears are engaged with each other for transmission;
• the telescopic structural member comprises a first adjusting rod, a second adjusting rod and an adjusting shaft connected with the transmission rod, wherein the first adjusting rod and the second adjusting rod are arranged to oppose each other and be spaced apart in an up-down direction, and the adjusting shaft is arranged between the first adjusting rod and the second adjusting rod and is engaged with the first adjusting rod and the second adjusting rod respectively for transmission;
• the upper-body outer housing is formed by a plurality of housing units connected end to end in sequence, and one of any two adjacent housing units is connected with the first adjusting rod and the other is connected with the second adjusting rod;
• the adjusting knob is connected with one of the adjusting shafts, wherein when the adjusting knob is rotated in a first rotation direction, the corresponding adjusting shaft is driven to rotate forward, driving the first adjusting rod to move in a first horizontal direction and driving the second adjusting rod to move in a second horizontal direction, wherein the first horizontal direction is opposite to the second horizontal direction, so that a distance between the two housing units connected with the first adjusting rod and the second adjusting rod respectively is gradually increased;
• and when the adjusting knob is rotated in a second rotation direction, the adjusting shaft is driven to rotate reversely, driving the first adjusting rod to move in the second horizontal direction and driving the second adjusting rod to move in the first horizontal direction, so that the distance between two housing units connected with the first adjusting rod and the second adjusting rod respectively is gradually reduced.
