[0011] The present invention is further described below in conjunction with an embodiment, but the present invention is not limited to the embodiment. Any similar structure and similar changes of the present invention should be included in the protection scope of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and is not a limitation on the technical solution of the present invention.

[0012] like Figure 1-Figure 3 As shown, a heat shrink furnace body device with a quick release mechanism of the utility model includes a bottom plate (not shown in the figure), two slide rails 14 are arranged in parallel on the bottom plate, a heat shrink furnace body 11 is arranged on the slide rails 14 through a slider, a driving device 12 is fixedly arranged on the bottom plate, a quick release mechanism 15 is arranged at the bottom of the heat shrink furnace body 11, and a power output shaft of the driving device 12 is connected to the quick release mechanism 15.

[0013] Further, the quick release mechanism 15 includes a fixed seat 21, the fixed seat 21 is fixed to the bottom of the heat shrink furnace body 11, a slide groove 25 is provided in the upper surface of the first side of the fixed seat 21, the upper end of the slide groove 25 is provided with an opening, and a locking piece 23 that can move up and down is provided in the slide groove 25. A first through hole 26 is provided on the side of the slide groove 25, that is, a side of the fixed seat 21, and a second through hole 27 coaxial with the first through hole 26 is provided in the locking piece 23. The power output shaft of the driving device 12 passes through the first through hole 26 and the second through hole 27. The power output shaft of the driving device 12 A groove 28 is provided on the output shaft, and the groove 28 is perpendicular to the axial direction of the power output shaft. A spring 24 is respectively connected between the two sides of the locking plate 23 and the bottom of the slide groove 25, and the spring 24 biases the locking plate 23 upward. A driving rod 13 is passed through the second side of the fixed seat 21, and the driving rod 13 and the fixed seat 21 form a rotating pair in the circumferential direction. A pressure plate 22 is provided above the fixed seat 21, and the driving rod 13 is fixedly connected to one side of the pressure plate 22, and the other side of the pressure plate 22 is pressed on the upper side of the locking plate 23, so that the locking plate 23 is stuck in the groove 28 and locked with the power output shaft of the driving device 12.

[0016] The working principle of this embodiment:

[0017] When the heat shrink furnace body 11 is operating normally, the power output shaft of the driving device 12 passes through the first through hole 26 and the second through hole 27, the pressure plate 22 is pressed on the locking plate 23, the locking plate 23 is inserted into the groove 28, the second through hole 27 deviates from the center of the first through hole 26, and the power output shaft of the driving device 12 is fixed to the locking plate 23 and the fixing seat 21. When the heating operation is performed, the power output shaft of the driving device 12 drives the heat shrink furnace body 11 to move forward along the slide rail 14, so that the wire rack enters the heat shrink furnace body 11. After the heating is completed, the power output shaft of the driving device 12 drives the heat shrink furnace body 11 to retreat, cool, and complete the operation.
