[0037] As shown in Figures 1 to 12 The utility model discloses a quick -wearing starting dial block structure can be quickly installed to the inside of C type card slot 200 (as shown in Figure 10 And Figure 12 The utility model discloses a quick -wearing starting dial block structure can be quickly installed to the inside of C type card slot 200 (as shown in

[0038] Among them, still include the pin shaft 60;Pin shaft 60 passes through pressure block 20 and eccentric dial wheel 40 in proper order;Pressure block 20 and eccentric dial wheel 40 realize relative rotation by pin shaft 60;Because the outer edge of eccentric dial wheel 40 adopts eccentric circle structure, therefore when eccentric dial wheel 40 is rotated, the distance of pin shaft 60 and the outer edge of eccentric dial wheel 40 will change, make pin shaft 60 can be relatively dial block main body 10 and move up and down, simultaneously because pressure block 20 and eccentric dial wheel 40 are connected by pin shaft 60, therefore can drive pressure block 20 and move up and down relative dial block main body 10.

[0039] Reset spring 50 is installed on dial block main body 10, reset spring 50 provides the elastic force of mutual approach of two locking blocks 30 to push pressure block 20 and drive eccentric dial wheel 40 and top the top of dial block main body 10;When eccentric dial wheel 40 rotates and drives pressure block 20 to move down, pressure block 20 pushes two locking blocks 30 and mutually away along the width direction of dial block main body 10, to realize locking;When eccentric dial wheel 40 rotates and drives pressure block 20 to move up, reset spring 50 drives two locking blocks 30 and mutually approach along the width direction of dial block main body 10.

[0040] When installing, as Figure 9As shown, this is the first usage state of the quick-release start-up lever structure of this utility model; the eccentric lever 40 is turned, causing it to rotate in direction A, and driving the pressure block 20 to move upward; at this time, the pressure block 20 does not press the locking block 30, so the locking blocks 30 on both sides are retracted into the lever body 10 under the elastic force of the reset spring 50; the overall width is reduced, at this time as... Figure 10 As shown, the main body 10 of the lever can extend into the C-shaped slot 200.

[0041] When locked, such as Figure 11 As shown, this is the second usage state of the quick-release start-up lever structure of this utility model; the eccentric lever 40 is turned, causing it to rotate in direction B, and driving the pressure block 20 to move downwards. At this time, the pressure block 20 pushes the locking block 30 to move outwards, protruding from the outer wall of the lever body 10; at this time, as... Figure 12 As shown, the locking block 30 abuts against the inner wall of the C-shaped slot 200, thus locking the start-up lever 100.

[0042] Please see Figure 5 and Figure 6 The main body 10 of the lever has a pin hole 12 extending along its width, and the pin hole 12 is connected to the movable groove 113. The bottom of the receiving cavity 11 has a slot 13 that is arranged opposite to the length of the main body 10, and an inverted buckle 14 that is arranged opposite to the length of the main body 10 on the inner side of the receiving cavity 11. The inverted buckle 14 is aligned vertically with the slot 13.

[0043] During assembly, firstly, the pressure block 20 is vertically installed into the vertical slot 111 from top to bottom, with the bottom of the pressure block 20 extending into the movable slot 113. Then, the eccentric dial wheel 40 is vertically installed into the movable slot 113 from bottom to top. Subsequently, the pin 60 is horizontally passed through the pin hole 12, and the pin 60 passes through the eccentric dial wheel 40 and the pressure block 20, completing the installation of the eccentric dial wheel 40, the pressure block 20, and the dial body 10. The two locking blocks 30 are then inserted into the receiving cavity 11 from the horizontal slots 112 on both sides. Next, the reset spring 50 is vertically inserted into the receiving cavity 11 through the vertical slot 111 and installed between the slot 13 and the inverted buckle 14. At this point, the reset spring 50 will connect with the two locking blocks 30, thus completing the installation of the locking blocks 30, the reset spring 50, and the dial body 10.

[0044] Furthermore, two limiting blocks 15 are provided inside the receiving cavity 11, extending along the width direction of the lever body 10 and arranged opposite to each other. The lower end of the limiting block 15 is provided with a positioning arc groove 151 for cooperating with the outer edge of the eccentric lever 40. After assembly, the outer edge of the eccentric lever 40 abuts against the positioning arc groove 151. When the eccentric lever 40 rotates, it can drive the pressure block 20 to move vertically relative to the lever body 10.

[0045] Furthermore, pre-installed protrusions 16 are provided on the outer side of the main body 10 of the lever, such as... Figure 9 As shown, when the main body 10 of the dial is inserted into the C-shaped slot 200, the pre-installed protrusion 16 can abut against the slot opening, playing a pre-installation role, preventing the main body 10 of the dial from falling off, and reducing the difficulty of installation. A storage slot 17 is provided at the bottom of the main body 10 of the dial. In this embodiment, two symmetrically distributed storage slots 17 are provided to store the eccentric dial 40, ensuring an aesthetically pleasing appearance.

A first through hole is provided in the connecting part 21 for connecting the pin.

[0048] Please see Figure 7 The locking block 30 has a sloping step 31 on the side facing the pressure block 20, which gradually slopes downwards towards the pressure block 20. When the pressure block 20 moves downwards, the wedge-shaped abutment surface 23 abuts against the sloping step 31. Due to the sloping design of the sloping step 31, the wedge-shaped abutment surface 23 pushes the sloping step 31, thereby causing the locking block 30 to move outwards along the width direction of the lever body 10. Slots 32 are provided on both sides of the locking block 30 for connecting with the reset spring 50. Meanwhile, teeth 33 are provided on the outer wall of the locking block 30. After the locking blocks 30 extend outwards on both sides, the teeth 33 can abut against the groove wall of the C-shaped slot 200, thus completing the locking connection between the starting lever 100 and the C-shaped slot 200.

[0049] Please see Figure 3 and Figure 4 The outer wall of the eccentric dial 40 extends a lever 41. When the eccentric dial 40 rotates to a certain angle, the lever 41 can be stored in the storage groove 17 at the bottom of the dial body 10.

[0050] Please see Figure 2 and Figure 3 The reset spring 50 includes a spring body 51, two elastic arms 52 perpendicular to the spring body 51, and a connector arm 53 located at the bottom of the spring body 51. When the reset spring 50 is installed into the receiving cavity 11, the connector arm 53 is inserted into the connector slot, and the inverted clip 14 abuts against the upper end of the spring body 51, thus installing the reset spring 50 into the receiving cavity 11. The two elastic arms 52 respectively overlap the slots 32 of the locking block 30, realizing the connection between the reset spring 50 and the locking block 30.
