[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. The quick-insert mandrel fixing structure is provided with a fixing block, a slide groove, a first spring, a first pillar and a stopper, and the mandrel is placed at the relative center of several fixing blocks. The mandrel is pressed downward, and the mandrel moves downward to squeeze the fixing block, so that the fixing block moves in the slide groove. During the movement of the fixing block, the stopper is driven by the first pillar to move on the outer wall of the placement disk. During the movement of the first pillar, the fixing block cooperates with the inner wall of the placement disk to squeeze the first spring. The first spring is squeezed and rebounds to squeeze the fixing block in the opposite direction, so that several fixing blocks are simultaneously contracted in the slide groove to fix the mandrel, and the traditional fixing structure usually uses a complex mechanical structure. There is no need to operate multiple parts at the same time during fixing, which is convenient to operate and ensures work efficiency.

When the core shaft is placed above the disk, the protruding part of the core shaft is located between the two clamping plates. The core shaft squeezes the clamping plate, and the clamping plate drives the baffle to move through the second pillar. During the movement, the clamping plate and the bracket cooperate to squeeze the second spring. After being squeezed, the second spring rebounds and drives the two clamping plates to move closer to each other to clamp the core shaft, which plays an auxiliary supporting role in the fixation of the core shaft. In this way, the core shaft is more stable when fixed, and the stability of the fixing structure is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a quick-insert core shaft fixing structure, including a bracket 1, one side of the bracket 1 is threadedly connected with a plurality of bolts 18, the number of the bolts 18 is four, the bracket 1 can be fixed to a certain place for use by the bolts 18, and the number of the bolts 18 is four, and the stability of the fixing structure during use is ensured by fixing with the bolts 18 during fixation, one side of the bracket 1 is threadedly connected with a threaded rod 2, the threaded rod 2 penetrates the bracket 1, one end of the threaded rod 2 is fixedly connected with a chassis 3, the end of the threaded rod 2 away from the chassis 3 is fixedly connected with a top plate 4, the top of the top plate 4 is fixedly connected with a limiting block 5, the top of the top plate 4 is fixedly connected with a rotating shaft 6, the top of the top plate 4 is rotatably connected with a placement plate 7 through the rotating shaft 6, a limiting groove 13 is provided on one side of the placement plate 7, the position of the limiting groove 13 corresponds to the position of the limiting block 5, through the limiting groove 13 and the limiting block 5 The cooperation between them makes the placing plate 7 rotate above the top plate through the rotating shaft 6, and the limiting effect of the limiting block 5 on the limiting groove 13 makes the placing plate 7 more stable when rotating above the top plate, and there will be no displacement. A plurality of sliding grooves 8 are provided on one side of the placing plate 7, and a fixing block 9 is slidably connected in the sliding groove 8. A first pillar 10 is fixedly connected to one side of the fixing block 9. The first pillar 10 passes through the placing plate 7, and a first spring 11 is connected to the outer sleeve of the first pillar 10. A stopper 12 is fixedly connected to one end of the first pillar 10 away from the fixing block 9. Because the first spring 11 is provided, when the mandrel is placed at the relative center of the plurality of fixing blocks 9, the mandrel squeezes the fixing block 9 so that the fixing block 9 moves in the sliding groove 8. The first spring 11 is squeezed during the movement of the fixing block 9. The first spring 11 rebounds quickly after being squeezed, so that the plurality of fixing blocks 9 clamp and fix the mandrel, and there is no need for excessive operation, which is convenient to use.
[0019] A plurality of second pillars 14 are provided on one side of the bracket 1, and one end of the corresponding two second pillars 14 is fixedly connected with a baffle 15, and a second spring 16 is connected to the outer sleeve of the second pillar 14. Due to the second spring 16, the clamping plate 17 is squeezed and moves on one side of the bracket 1 through the second pillar 14, so that the second spring 16 is squeezed. After being squeezed, the second spring 16 rebounds and drives the clamping plate 17 to assist in clamping the mandrel, so that the mandrel is more stable when fixed. The end of the second pillar 14 away from the baffle 15 is fixedly connected with a clamping plate 17, and the clamping plate 17 is concave in design. There are two clamping plates 17, and the position of the clamping plate 17 corresponds to the position of the fixing block 9. Due to the provision of the clamping plate 17, and the clamping plate 17 is concave in design, when the mandrel is fixed, the protruding part is clamped by the recessed part of the clamping plate 17, and the clamping plate 17 plays a role of auxiliary fixing of the mandrel when fixed, so that the mandrel is more stable when fixed.
[0020] The working principle of the utility model is as follows: the bracket 1 is fixed at a certain place by a bolt 18, and the threaded rod 2 is screwed. Since the threaded rod 2 and the bracket 1 are threadedly connected, the threaded rod 2 is rotated to adjust the height of the placement disk 7, and then the core shaft is placed at the center corresponding to a plurality of fixed blocks 9 and pressed downward, and the outer wall of the core shaft moves downward to squeeze the fixed block 9, so that the fixed block 9 moves in the slide groove 8. During the movement of the fixed block 9, the stopper 12 is driven to move by the first pillar 10, and the fixed block 9 cooperates with the inner wall of the placement disk 7 so that the first spring 11 is squeezed, and the first spring 11 is squeezed and rebounds to squeeze the fixed block 9. Through the cooperation between the first spring 11 and the fixed block 9, the fixed block 9 fixes the core shaft, and the placement disk 7 is rotated by the rotating shaft 6. The placement disk 7 is rotated above the top disk 4 to adjust the angle. The protruding part of the core shaft is between the two clamping plates 17, and the clamping plate 17 is squeezed and then squeezes the second spring 16. The second spring 16 rebounds and drives the two clamping plates 17 to approach each other, so that the two clamping plates 17 assist in fixing the core shaft.
